Working memory: a developmental study of phonological recoding.
Palmer, S
A cross-sectional study using children aged 3 to 7 years and a cross-sequential study using children aged between 5 and 8 years showed that the development of phonological recoding in working memory was more complex than the simple dichotomous picture portrayed in the current literature. It appears that initially children use no strategy in recall, which is proposed to represent the level of automatic activation of representations in long-term memory and the storage capacity of the central executive. This is followed by a period in which a visual strategy prevails, followed by a period of dual visual-verbal coding before the adult-like strategy of verbal coding finally emerges. The results are discussed in terms of three working memory models (Baddeley, 1990; Engle, 1996; Logie, 1996) where strategy use is seen as the development of attentional processes and phonological recoding as the development of inhibitory mechanisms in the central executive to suppress the habitual response set of visual coding.
Does phonological recoding occur during silent reading and is it necessary for orthographic learning?
de Jong, P.F.; Bitter, D.J.L.; van Setten, M.; Marinus, E.
Two studies were conducted to test the central claim of the self-teaching hypothesis (i.e., phonological recoding is necessary for orthographic learning) in silent reading. The first study aimed to demonstrate the use of phonological recoding during silent reading. Texts containing pseudowords were
Developmental delays in phonological recoding among children and adolescents with Down syndrome and Williams syndrome.
Danielsson, Henrik; Henry, Lucy; Messer, David; Carney, Daniel P J; Rönnberg, Jerker
This study examined the development of phonological recoding in short-term memory (STM) span tasks among two clinical groups with contrasting STM and language profiles: those with Down syndrome (DS) and Williams syndrome (WS). Phonological recoding was assessed by comparing: (1) performance on phonologically similar and dissimilar items (phonological similarity effects, PSE); and (2) items with short and long names (word length effects, WLE). Participant groups included children and adolescents with DS (n=29), WS (n=25) and typical development (n=51), all with average mental ages around 6 years. The group with WS, contrary to predictions based on their relatively strong verbal STM and language abilities, showed no evidence for phonological recoding. Those in the group with DS, with weaker verbal STM and language abilities, showed positive evidence for phonological recoding (PSE), but to a lesser degree than the typical group (who showed PSE and WLE). These findings provide new information about the memory systems of these groups of children and adolescents, and suggest that STM processes involving phonological recoding do not fit with the usual expectations of the abilities of children and adolescents with WS and DS.

Probabilistic sensory recoding.
Jazayeri, Mehrdad
A hallmark of higher brain functions is the ability to contemplate the world rather than to respond reflexively to it. To do so, the nervous system makes use of a modular architecture in which sensory representations are dissociated from areas that control actions. This flexibility however necessitates a recoding scheme that would put sensory information to use in the control of behavior. Sensory recoding faces two important challenges. First, recoding must take into account the inherent variability of sensory responses. Second, it must be flexible enough to satisfy the requirements of different perceptual goals. Recent progress in theory, psychophysics, and neurophysiology indicate that cortical circuitry might meet these challenges by evaluating sensory signals probabilistically.
Phonological coding during reading.
Leinenger, Mallorie
The exact role that phonological coding (the recoding of written, orthographic information into a sound based code) plays during silent reading has been extensively studied for more than a century. Despite the large body of research surrounding the topic, varying theories as to the time course and function of this recoding still exist. The present review synthesizes this body of research, addressing the topics of time course and function in tandem. The varying theories surrounding the function of phonological coding (e.g., that phonological codes aid lexical access, that phonological codes aid comprehension and bolster short-term memory, or that phonological codes are largely epiphenomenal in skilled readers) are first outlined, and the time courses that each maps onto (e.g., that phonological codes come online early [prelexical] or that phonological codes come online late [postlexical]) are discussed. Next the research relevant to each of these proposed functions is reviewed, discussing the varying methodologies that have been used to investigate phonological coding (e.g., response time methods, reading while eye-tracking or recording EEG and MEG, concurrent articulation) and highlighting the advantages and limitations of each with respect to the study of phonological coding. In response to the view that phonological coding is largely epiphenomenal in skilled readers, research on the use of phonological codes in prelingually, profoundly deaf readers is reviewed. Finally, implications for current models of word identification (activation-verification model, Van Orden, 1987; dual-route model, e.g., M. Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001; parallel distributed processing model, Seidenberg & McClelland, 1989) are discussed. (PsycINFO Database Record (c) 2014 APA, all rights reserved).
Examining the Relationship between Immediate Serial Recall and Immediate Free Recall: Common Effects of Phonological Loop Variables but Only Limited Evidence for the Phonological Loop

A test of the orthographic recoding hypothesis
Gaygen, Daniel E.
The Orthographic Recoding Hypothesis [D. E. Gaygen and P. A. Luce, Percept. Psychophys. 60, 465-483 (1998)] was tested. According to this hypothesis, listeners recognize spoken words heard for the first time by mapping them onto stored representations of the orthographic forms of the words. Listeners have a stable orthographic representation of words, but no phonological representation, when those words have been read frequently but never heard or spoken. Such may be the case for low frequency words such as jargon. Three experiments using visually and auditorily presented nonword stimuli tested this hypothesis. The first two experiments were explicit tests of memory (old-new tests) for words presented visually. In the first experiment, the recognition of auditorily presented nonwords was facilitated when they previously appeared on a visually presented list. The second experiment was similar, but included a concurrent articulation task during a visual word list presentation, thus preventing covert rehearsal of the nonwords. The results were similar to the first experiment. The third experiment was an indirect test of memory (auditory lexical decision task) for visually presented nonwords. Auditorily presented nonwords were identified as nonwords significantly more slowly if they had previously appeared on the visually presented list accompanied by a concurrent articulation task.
Recall of short word lists presented visually at fast rates: effects of phonological similarity and word length.
Coltheart, V; Langdon, R
Phonological similarity of visually presented list items impairs short-term serial recall. Lists of long words are also recalled less accurately than are lists of short words. These results have been attributed to phonological recoding and rehearsal. If subjects articulate irrelevant words during list presentation, both phonological similarity and word length effects are abolished. Experiments 1 and 2 examined effects of phonological similarity and recall instructions on recall of lists shown at fast rates (from one item per 0.114-0.50 sec), which might not permit phonological encoding and rehearsal. In Experiment 3, recall instructions and word length were manipulated using fast presentation rates. Both phonological similarity and word length effects were observed, and they were not dependent on recall instructions. Experiments 4 and 5 investigated the effects of irrelevant concurrent articulation on lists shown at fast rates. Both phonological similarity and word length effects were removed by concurrent articulation, as they were with slow presentation rates.
Examining the relationship between immediate serial recall and immediate free recall: common effects of phonological loop variables but only limited evidence for the phonological loop.
Spurgeon, Jessica; Ward, Geoff; Matthews, William J
We examined the contribution of the phonological loop to immediate free recall (IFR) and immediate serial recall (ISR) of lists of between one and 15 words. Following Baddeley (1986, 2000, 2007, 2012), we assumed that visual words could be recoded into the phonological store when presented silently but that recoding would be prevented by concurrent articulation (CA; Experiment 1). We further assumed that the use of the phonological loop would be evidenced by greater serial recall for lists of phonologically dissimilar words relative to lists of phonologically similar words (Experiments 2A and 2B). We found that in both tasks, (a) CA reduced recall; (b) participants recalled short lists from the start of the list, leading to enhanced forward-ordered recall; (c) participants were increasingly likely to recall longer lists from the end of the list, leading to extended recency effects; (d) there were significant phonological similarity effects in ISR and IFR when both were analyzed using serial recall scoring; (e) these were reduced by free recall scoring and eliminated by CA; and (f) CA but not phonological similarity affected the tendency to initiate recall with the first list item. We conclude that similar mechanisms underpin ISR and IFR. Critically, the phonological loop is not strictly necessary for the forward-ordered recall of short lists on both tasks but may augment recall by increasing the accessibility of the list items (relative to CA), and in so doing, the order of later items is preserved better in phonologically dissimilar than in phonologically similar lists.

Reevaluating Key Evidence for the Development of Rehearsal: Phonological Similarity Effects in Children Are Subject to Proportional Scaling Artifacts
Jarrold, Christopher; Citroen, Rebecca
The size of an individual's phonological similarity effect for visually presented material is assumed to reflect his or her ability to recode, and by implication rehearse, information in verbal short-term memory. Many studies have shown that under these conditions, the size of this effect interacts with age, tending to be nonsignificant in…
Recode-2: new design, new search tools, and many more genes.
LENUS (Irish Health Repository)
Bekaert, Michaël
\\'Recoding\\' is a term used to describe non-standard read-out of the genetic code, and encompasses such phenomena as programmed ribosomal frameshifting, stop codon readthrough, selenocysteine insertion and translational bypassing. Although only a small proportion of genes utilize recoding in protein synthesis, accurate annotation of \\'recoded\\' genes lags far behind annotation of \\'standard\\' genes. In order to address this issue, provide a service to researchers in the field, and offer training data for developers of gene-annotation software, we have gathered together known cases of recoding within the Recode database. Recode-2 is an improved and updated version of the database. It provides access to detailed information on genes known to utilize translational recoding and allows complex search queries, browsing of recoding data and enhanced visualization of annotated sequence elements. At present, the Recode-2 database stores information on approximately 1500 genes that are known to utilize recoding in their expression--a factor of approximately three increase over the previous version of the database. Recode-2 is available at http:\\/\\/recode.ucc.ie.
Relationship between phonological awareness and spelling proficiency in first-grade students
Directory of Open Access Journals (Sweden)
Nasibe Soltaninejad
Full Text Available Background and Aim: Phonological awareness (consisting of phoneme, syllable and intra-syllable awareness is an important part of receptive and expressive language; it facilitates reading and writing skills through phonological re-coding. Multiple studies in several languages have studied the relationship between phonological awareness and dictation. This research is based on a study of the relationship between phonological skill and spelling score in first-grade Persian students.Methods: Four hundred first-grade students participated in the study, including 209 girls and 191 boys. A phonological awareness test was individually administered for each student and then a spelling exam was administered in groups. The correlation between the two tests was studied using a simple regression model. The comparison of mean scores of girls and boys was evaluated employing an independent t-test.Results: A correlation coefficient of 0.82 was obtained between phonological awareness and spelling proficiency (p<0.001. Phonological skill sub-tests also showed a significant correlation with spelling proficiency (highest for phoneme awareness r=0.34 and lowest for rhyme awareness r=0.12. The mean scores of girls and boys differed significantly (p<0.05.Conclusion: There is a strong positive association between phonological awareness and spelling proficiency. Therefore, if phonological skill is improved, spelling score can be enhanced.
Visual short-term store can compensate for a defective phonological short-term store in patients with apraxia of speech.
Silveri, Maria Caterina; Baldonero, Eleonora
The aim of the study was to investigate whether, within the phonological short-term memory (STM) system, speech articulation disorders primarily due to cortical damage are associated with deficits in the phonological recoding of visual-verbal material, and whether the visual short-term store (STS) can compensate for inefficient access to the phonological STS, as suggested in previous reports. Two patients (AE and TM) with apraxia of speech due to atrophic cerebral damage were administered a battery of tasks devised to explore the organization of the phonological STM. AE's span was normal and TM's span was markedly reduced. Phonological similarity and word-length effects: Both patients showed the effects in visual presentation; the effect was less evident in verbal presentation. This suggests a phonological STS disorder and preserved rehearsal/phonological recoding, consistently with involvement of the left parietal regions, which was documented by the MRI in both patients. Unexpectedly, TM had a longer span for similar than for dissimilar words in visually presented stimuli. Silent phonology (on written material): At variance with controls, stress assignment improved during unattended speech both in AE and TM, while in both patients and controls a detrimental effect of unattended speech was documented in the initial sound task. To account for this unusual pattern of results, we hypothesized that whenever possible, AE and TM adopt the strategy that takes advantage of the visual STM store to compensate for a defective phonological STS.

The phonological loop unmasked? A comment on the evidence for a "perceptual-gestural" alternative.
Baddeley, Alan D; Larsen, Janet D
Jones et al. (Jones, Hughes, & Macken, 2006; Jones, Macken, & Nicholls, 2004) identify the interaction between phonological similarity, articulatory suppression, and stimulus presentation mode in verbal short-term memory as potentially providing important support for the phonological loop hypothesis. They find such an interaction but attribute it to "perceptual organization masquerading as phonological storage". We present data using shorter letter sequences and find clear evidence of the interaction predicted by the phonological loop hypothesis, which, unlike the evidence of Jones et al., is not limited to recency, and which provides continued support for the phonological loop hypothesis.

The role of the phonological loop in English word learning: a comparison of Chinese ESL learners and native speakers.
Hamada, Megumi; Koda, Keiko
Although the role of the phonological loop in word-retention is well documented, research in Chinese character retention suggests the involvement of non-phonological encoding. This study investigated whether the extent to which the phonological loop contributes to learning and remembering visually introduced words varies between college-level Chinese ESL learners (N = 20) and native speakers of English (N = 20). The groups performed a paired associative learning task under two conditions (control versus articulatory suppression) with two word types (regularly spelled versus irregularly spelled words) differing in degree of phonological accessibility. The results demonstrated that both groups' recall declined when the phonological loop was made less available (with irregularly spelled words and in the articulatory suppression condition), but the decline was greater for the native group. These results suggest that word learning entails phonological encoding uniformly across learners, but the contribution of phonology varies among learners with diverse linguistic backgrounds.

Phonology without universal grammar.
Archangeli, Diana; Pulleyblank, Douglas
The question of identifying the properties of language that are specific human linguistic abilities, i.e., Universal Grammar, lies at the center of linguistic research. This paper argues for a largely Emergent Grammar in phonology, taking as the starting point that memory, categorization, attention to frequency, and the creation of symbolic systems are all nonlinguistic characteristics of the human mind. The articulation patterns of American English rhotics illustrate categorization and systems; the distribution of vowels in Bantu vowel harmony uses frequencies of particular sequences to argue against Universal Grammar and in favor of Emergent Grammar; prefix allomorphy in Esimbi illustrates the Emergent symbolic system integrating phonological and morphological generalizations. The Esimbi case has been treated as an example of phonological opacity in a Universal Grammar account; the Emergent analysis resolves the pattern without opacity concerns.

Recoded and nonrecoded trinary signed-digit adders and multipliers with redundant-bit representations
Cherri, Abdallah K.; Alam, Mohammed S.
Highly-efficient two-step recoded and one-step nonrecoded trinary signed-digit (TSD) carry-free adders subtracters are presented on the basis of redundant-bit representation for the operands digits. It has been shown that only 24 (30) minterms are needed to implement the two-step recoded (the one-step nonrecoded) TSD addition for any operand length. Optical implementation of the proposed arithmetic can be carried out by use of correlation- or matrix-multiplication-based schemes, saving 50% of the system memory. Furthermore, we present four different multiplication designs based on our proposed recoded and nonrecoded TSD adders. Our multiplication designs require a small number of reduced minterms to generate the multiplication partial products. Finally, a recently proposed pipelined iterative-tree algorithm can be used in the TSD adders multipliers; consequently, efficient use of all available adders can be made.

Phonological similarity effect in complex span task.
Camos, Valérie; Mora, Gérôme; Barrouillet, Pierre
The aim of our study was to test the hypothesis that two systems are involved in verbal working memory; one is specifically dedicated to the maintenance of phonological representations through verbal rehearsal while the other would maintain multimodal representations through attentional refreshing. This theoretical framework predicts that phonologically related phenomena such as the phonological similarity effect (PSE) should occur when the domain-specific system is involved in maintenance, but should disappear when concurrent articulation hinders its use. Impeding maintenance in the domain-general system by a concurrent attentional demand should impair recall performance without affecting PSE. In three experiments, we manipulated the concurrent articulation and the attentional demand induced by the processing component of complex span tasks in which participants had to maintain lists of either similar or dissimilar words. Confirming our predictions, PSE affected recall performance in complex span tasks. Although both the attentional demand and the articulatory requirement of the concurrent task impaired recall, only the induction of an articulatory suppression during maintenance made the PSE disappear. These results suggest a duality in the systems devoted to verbal maintenance in the short term, constraining models of working memory.

Full Text Available This article attempts to investigate how much of phonology can be explained by properties of general cognition and the Sensorimotor system — in other words, third-factor principles, in support of the evolutionary scenario posed by Hauser et al. (2002a. It argues against Pinker & Jackendoff's (2005: 212 claim that "major characteristics of phonology are specific to language (or to language & music, [and] uniquely human," and their conclusion that "phonology represents a major counterexample to the recursion-only hypothesis." Contrary to the statements by Anderson (2004 and Yip (2006a, 2006b to the effect that phonology has not been tested in animals, it is shown that virtually all the abilities that underlie phonological competence have been shown in other species.
Phonological learning in semantic dementia.
Jefferies, Elizabeth; Bott, Samantha; Ehsan, Sheeba; Lambon Ralph, Matthew A
Patients with semantic dementia (SD) have anterior temporal lobe (ATL) atrophy that gives rise to a highly selective deterioration of semantic knowledge. Despite pronounced anomia and poor comprehension of words and pictures, SD patients have well-formed, fluent speech and normal digit span. Given the intimate connection between phonological STM and word learning revealed by both neuropsychological and developmental studies, SD patients might be expected to show good acquisition of new phonological forms, even though their ability to map these onto meanings is impaired. In contradiction of these predictions, a limited amount of previous research has found poor learning of new phonological forms in SD. In a series of experiments, we examined whether SD patient, GE, could learn novel phonological sequences and, if so, under which circumstances. GE showed normal benefits of phonological knowledge in STM (i.e., normal phonotactic frequency and phonological similarity effects) but reduced support from semantic memory (i.e., poor immediate serial recall for semantically degraded words, characterised by frequent item errors). Next, we demonstrated normal learning of serial order information for repeated lists of single-digit number words using the Hebb paradigm: these items were well-understood allowing them to be repeated without frequent item errors. In contrast, patient GE showed little learning of nonsense syllable sequences using the same Hebb paradigm. Detailed analysis revealed that both GE and the controls showed a tendency to learn their own errors as opposed to the target items. Finally, we showed normal learning of phonological sequences for GE when he was prevented from repeating his errors. These findings confirm that the ATL atrophy in SD disrupts phonological processing for semantically degraded words but leaves the phonological architecture intact. Consequently, when item errors are minimised, phonological STM can support the acquisition of new phoneme
Phonological Concept Learning.
Moreton, Elliott; Pater, Joe; Pertsova, Katya
Linguistic and non-linguistic pattern learning have been studied separately, but we argue for a comparative approach. Analogous inductive problems arise in phonological and visual pattern learning. Evidence from three experiments shows that human learners can solve them in analogous ways, and that human performance in both cases can be captured by the same models. We test GMECCS (Gradual Maximum Entropy with a Conjunctive Constraint Schema), an implementation of the Configural Cue Model (Gluck & Bower, ) in a Maximum Entropy phonotactic-learning framework (Goldwater & Johnson, ; Hayes & Wilson, ) with a single free parameter, against the alternative hypothesis that learners seek featurally simple algebraic rules ("rule-seeking"). We study the full typology of patterns introduced by Shepard, Hovland, and Jenkins () ("SHJ"), instantiated as both phonotactic patterns and visual analogs, using unsupervised training. Unlike SHJ, Experiments 1 and 2 found that both phonotactic and visual patterns that depended on fewer features could be more difficult than those that depended on more features, as predicted by GMECCS but not by rule-seeking. GMECCS also correctly predicted performance differences between stimulus subclasses within each pattern. A third experiment tried supervised training (which can facilitate rule-seeking in visual learning) to elicit simple rule-seeking phonotactic learning, but cue-based behavior persisted. We conclude that similar cue-based cognitive processes are available for phonological and visual concept learning, and hence that studying either kind of learning can lead to significant insights about the other.

Full Text Available The article discusses a new approach to upgrade the software for SCADA-systems. A distinctive feature of this method is the ability to support more than ten most popular programming languages. By applying this method it's possible to automate the process of recoding software components and, by doing so, it saves time programmers have to spend to rewrite the code and reduce the likelihood of structural errors inherited from the previous system.
Recoding between two types of STM representation revealed by the dynamics of memory search.
Leszczyński, Marcin; Myers, Nicholas E; Akyürek, Elkan G; Schubö, Anna
Visual STM (VSTM) is thought to be related to visual attention in several ways. Attention controls access to VSTM during memory encoding and plays a role in the maintenance of stored information by strengthening memorized content. We investigated the involvement of visual attention in recall from VSTM. In two experiments, we measured electrophysiological markers of attention in a memory search task with varying intervals between VSTM encoding and recall, and so we were able to track recoding of representations in memory. Results confirmed the involvement of attention in VSTM recall. However, the amplitude of the N2pc and N3rs components, which mark orienting of attention and search within VSTM, decreased as a function of delay. Conversely, the amplitude of the P3 and sustained posterior contralateral negativity components increased as a function of delay, effectively the opposite of the N2pc and N3rs modulations. These effects were only observed when verbal memory was not taxed. Thus, the results suggested that gradual recoding from visuospatial orienting of attention into verbal recall mechanisms takes place from short to long retention intervals. Interestingly, recall at longer delays was faster than at short delays, indicating that verbal representation is coupled with faster responses. These results extend the orienting-of-attention hypothesis by including an account of representational recoding during short-term consolidation and its consequences for recall from VSTM.

A recoding method to improve the humoral immune response to an HIV DNA vaccine.
Directory of Open Access Journals (Sweden)
Yaoxing Huang
Full Text Available This manuscript describes a novel strategy to improve HIV DNA vaccine design. Employing a new information theory based bioinformatic algorithm, we identify a set of nucleotide motifs which are common in the coding region of HIV, but are under-represented in genes that are highly expressed in the human genome. We hypothesize that these motifs contribute to the poor protein expression of gag, pol, and env genes from the c-DNAs of HIV clinical isolates. Using this approach and beginning with a codon optimized consensus gag gene, we recode the nucleotide sequence so as to remove these motifs without modifying the amino acid sequence. Transfecting the recoded DNA sequence into a human kidney cell line results in doubling the gag protein expression level compared to the codon optimized version. We then turn both sequences into DNA vaccines and compare induced antibody response in a murine model. Our sequence, which has the motifs removed, induces a five-fold increase in gag antibody response compared to the codon optimized vaccine.

Auto-Regulatory RNA Editing Fine-Tunes mRNA Re-Coding and Complex Behaviour in Drosophila
Savva, Yiannis A.; Jepson, James E.C; Sahin, Asli; Sugden, Arthur U.; Dorsky, Jacquelyn S.; Alpert, Lauren; Lawrence, Charles; Reenan, Robert A.
Auto-regulatory feedback loops are a common molecular strategy used to optimize protein function. In Drosophila many mRNAs involved in neuro-transmission are re-coded at the RNA level by the RNA editing enzyme dADAR, leading to the incorporation of amino acids that are not directly encoded by the genome. dADAR also re-codes its own transcript, but the consequences of this auto-regulation in vivo are unclear. Here we show that hard-wiring or abolishing endogenous dADAR auto-regulation dramatically remodels the landscape of re-coding events in a site-specific manner. These molecular phenotypes correlate with altered localization of dADAR within the nuclear compartment. Furthermore, auto-editing exhibits sexually dimorphic patterns of spatial regulation and can be modified by abiotic environmental factors. Finally, we demonstrate that modifying dAdar auto-editing affects adaptive complex behaviors. Our results reveal the in vivo relevance of auto-regulatory control over post-transcriptional mRNA re-coding events in fine-tuning brain function and organismal behavior. PMID:22531175

Computer design and chemical synthesis generated viable variants of poliovirus type 1 (PV1), whose ORF (6,189 nucleotides) carried up to 1,297 "Max" mutations (excess of overrepresented synonymous codon pairs) or up to 2,104 "SD" mutations (randomly scrambled synonymous codons). "Min" variants (excess of underrepresented synonymous codon pairs) are nonviable except for P2 Min , a variant temperature-sensitive at 33 and 39.5 °C. Compared with WT PV1, P2 Min displayed a vastly reduced specific infectivity (si) (WT, 1 PFU/118 particles vs. P2 Min , 1 PFU/35,000 particles), a phenotype that will be discussed broadly. Si of haploid PV presents cellular infectivity of a single genotype. We performed a comprehensive analysis of sequence and structures of the PV genome to determine if evolutionary conserved cis-acting packaging signal(s) were preserved after recoding. We showed that conserved synonymous sites and/or local secondary structures that might play a role in determining packaging specificity do not survive codon pair recoding. This makes it unlikely that numerous "cryptic, sequence-degenerate, dispersed RNA packaging signals mapping along the entire viral genome" [Patel N, et al. (2017) Nat Microbiol 2:17098] play the critical role in poliovirus packaging specificity. Considering all available evidence, we propose a two-step assembly strategy for +ssRNA viruses: step I, acquisition of packaging specificity, either ( a ) by specific recognition between capsid protein(s) and replication proteins (poliovirus), or ( b ) by the high affinity interaction of a single RNA packaging signal (PS) with capsid protein(s) (most +ssRNA viruses so far studied); step II, cocondensation of genome/capsid precursors in which an array of hairpin structures plays a role in virion formation.
Gradient phonological inconsistency affects vocabulary learning.
Muench, Kristin L; Creel, Sarah C
Learners frequently experience phonologically inconsistent input, such as exposure to multiple accents. Yet, little is known about the consequences of phonological inconsistency for language learning. The current study examines vocabulary acquisition with different degrees of phonological inconsistency, ranging from no inconsistency (e.g., both talkers call a picture /vig/) to mild but detectable inconsistency (e.g., one talker calls a picture a /vig/, and the other calls it a /vIg/), up to extreme inconsistency (e.g., the same picture is both a /vig/ and a /dIdʒ/). Previous studies suggest that learners readily extract consistent phonological patterns, given variable input. However, in Experiment 1, adults acquired phonologically inconsistent vocabularies more slowly than phonologically consistent ones. Experiment 2 examined whether word-form inconsistency alone, without phonological competition, was a source of learning difficulty. Even without phonological competition, listeners learned faster in 1 accent than in 2 accents, but they also learned faster in 2 accents (/vig/ = /vIg/) than with completely different labels (/vig/ = /dIdʒ/). Overall, results suggest that learners exposed to multiple accents may experience difficulty learning when 2 forms mismatch by more than 1 phonological feature, plus increased phonological competition due to a greater number of word forms. Implications for learning from variable input are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.
Phonological awareness and sinusoidal amplitude modulation in phonological dislexia.
Peñaloza-López, Yolanda; Herrera-Rangel, Aline; Pérez-Ruiz, Santiago J; Poblano, Adrián
Dyslexia is the difficulty of children in learning to read and write as results of neurological deficiencies. The objective was to test the Phonological awareness (PA) and Sinusoidal amplitude modulation (SAM) threshold in children with Phonological dyslexia (PD). We performed a case-control, analytic, cross sectional study. We studied 14 children with PD and 14 control children from 7 to 11 years of age, by means of PA measurement and by SAM test. The mean age of dyslexic children was 8.39 years and in the control group was 8.15. Children with PD exhibited inadequate skills in PA, and SAM. We found significant correlations between PA and SAM at 4 Hertz frequency, and calculated regression equations that predicts between one-fourth and one-third of variance of measurements. Alterations in PA and SAM found can help to explain basis of deficient language processing exhibited by children with PD.
The contribution of phonological short-term memory to artificial grammar learning.
Andrade, Jackie; Baddeley, Alan
Three experiments investigated the contribution of phonological short-term memory (STM) to grammar learning by manipulating rehearsal during study of an auditory artificial grammar made up from a vocabulary of spoken Mandarin syllables. Experiment 1 showed that concurrent, irrelevant articulation impaired grammar learning compared with a nonverbal control task. Experiment 2 replicated and extended this finding, showing that repeating the grammatical strings at study improved grammar learning compared with suppressing rehearsal or remaining silent during learning. Experiment 3 found no effects of rehearsal on grammar learning once participants had learned the component syllables. The findings suggest that phonological STM aids artificial grammar learning via effects on vocabulary learning.
Incremental phonological encoding during unscripted sentence production
Directory of Open Access Journals (Sweden)
Florian T Jaeger
Full Text Available We investigate phonological encoding during unscripted sentence production, focusing on the effect of phonological overlap on phonological encoding. Previous work on this question has almost exclusively employed isolated word production or highly scripted multiword production. These studies have led to conflicting results: some studies found that phonological overlap between two words facilitates phonological encoding, while others found inhibitory effects. One worry with many of these paradigms is that they involve processes that are not typical to everyday language use, which calls into question to what extent their findings speak to the architectures and mechanisms underlying language production. We present a paradigm to investigate the consequences of phonological overlap between words in a sentence while leaving speakers much of the lexical and structural choices typical in everyday language use. Adult native speakers of English described events in short video clips. We annotated the presence of disfluencies and the speech rate at various points throughout the sentence, as well as the constituent order. We find that phonological overlap has an inhibitory effect on phonological encoding. Specifically, if adjacent content words share their phonological onset (e.g., hand the hammer, they are preceded by production difficulty, as reflected in fluency and speech rate. We also find that this production difficulty affects speakers' constituent order preferences during grammatical encoding. We discuss our results and previous works to isolate the properties of other paradigms that resulted in facilitatory or inhibitory results. The data from our paradigm also speak to questions about the scope of phonological planning in unscripted speech and as to whether phonological and grammatical encoding interact.

Adult word recognition is influenced by prior exposure to phonologically or semantically related words ("cup" primes "cat" or "plate") compared to unrelated words ("door"), suggesting that words are organised in the adult lexicon based on their phonological and semantic properties and that word recognition implicates not just the heard word, but…

Can a bird brain do phonology?
Directory of Open Access Journals (Sweden)
Bridget D. Samuels
Full Text Available A number of recent studies have revealed correspondences between song- and language-related neural structures, pathways, and gene expression in humans and songbirds. Analyses of vocal learning, song structure, and the distribution of song elements have similarly revealed a remarkable number of shared characteristics with human speech. This article reviews recent developments in the understanding of these issues with reference to the phonological phenomena observed in human language. This investigation suggests that birds possess a host of abilities necessary for human phonological computation, as evidenced by behavioral, neuroanatomical, and molecular genetic studies. Vocal-learning birds therefore present an excellent model for studying some areas of human phonology, though differences in the primitives of song and language as well as the absence of a human-like morphosyntax make human phonology differ from birdsong phonology in crucial ways.

Zahra Soleymani
Full Text Available Objective: To determine phonological processing in elemantery children with Down syndrome Materials and Methods: Phonetic test is used to extract phonological processing in 40 child with Down syndrome .They were normal in hearing and oral structure. Results: There was significant difference between girls and boys in some subgroups of phonological processing. In assimilation, voiceless assimilation in boys and complete assimilation in girls were the most. Nasal assimilation in girls and fricative assimilation in boys were the least. In substitution, the least mean belonged to liquid and nasal substitution in girls and voice ness substitution in boys. In general there was no significant difference between age and phonological awareness; however, there was direct correlation between syllable structure and age and reverse correlation between age and stop assimilation. Conclusion: In addition to 3 groups of phonological processing including: syllable structure, assimilation, and substitution, omission was seen. The difference between girls and boys indicates they are impressed by the phonetic structure of words in different ways. Correlation between age and phonological processing shows phonological errors may be resulted from deviation.
[Working memory, phonological awareness and spelling hypothesis].
Gindri, Gigiane; Keske-Soares, Márcia; Mota, Helena Bolli
Working memory, phonological awareness and spelling hypothesis. To verify the relationship between working memory, phonological awareness and spelling hypothesis in pre-school children and first graders. Participants of this study were 90 students, belonging to state schools, who presented typical linguistic development. Forty students were preschoolers, with the average age of six and 50 students were first graders, with the average age of seven. Participants were submitted to an evaluation of the working memory abilities based on the Working Memory Model (Baddeley, 2000), involving phonological loop. Phonological loop was evaluated using the Auditory Sequential Test, subtest 5 of Illinois Test of Psycholinguistic Abilities (ITPA), Brazilian version (Bogossian & Santos, 1977), and the Meaningless Words Memory Test (Kessler, 1997). Phonological awareness abilities were investigated using the Phonological Awareness: Instrument of Sequential Assessment (CONFIAS - Moojen et al., 2003), involving syllabic and phonemic awareness tasks. Writing was characterized according to Ferreiro & Teberosky (1999). Preschoolers presented the ability of repeating sequences of 4.80 digits and 4.30 syllables. Regarding phonological awareness, the performance in the syllabic level was of 19.68 and in the phonemic level was of 8.58. Most of the preschoolers demonstrated to have a pre-syllabic writing hypothesis. First graders repeated, in average, sequences of 5.06 digits and 4.56 syllables. These children presented a phonological awareness of 31.12 in the syllabic level and of 16.18 in the phonemic level, and demonstrated to have an alphabetic writing hypothesis. The performance of working memory, phonological awareness and spelling level are inter-related, as well as being related to chronological age, development and scholarity.
Recoding of Information as a Component of Cognitive Training Technologies in the Course "Engineering Graphics"

I. N. Lunina
Full Text Available The efficiency to understand scientific and technical information is a relevant problem for a modern type of students. It is particularly acute for the freshmen learning the course of engineering graphics, which is one of the basic disciplines in engineering education.This problem, generally, arises from the information blow-up and cognitive students' deficiency. The students need to perceive, understand, take in, and apply a huge amount of information to acquire obligatory professional competencies. The cognitive deficiency is because of the poor school knowledge in geometry and graphics, underdeveloped spatial and logical thinking, lack of skills to work with educational and reference books, clip thinking.The modern engineering graphics teaches a technology for the visual presentation of information, graphical illustration, and interpretation of scientific and technical texts. The text is considered to be a completed piece of information that is described in any way – verbal, graphical, symbolic. Graphical language is a professionally oriented language of engineers.One of the components of cognitive learning technologies aimed at understanding the meaning of the studied texts is the development the skills for recoding some information, because a criterion of understanding the meaning of the text is the independent student's ability to represent the verbal texts in the form of drawings, blueprints, charts, diagrams, tables, formulae, and numeric entries.The article explores some examples of transcoding texts used in the course of engineering graphics (in lectures, seminars, homework, tests. It is emphasized that integrated presentation (verbal + graphical + symbolic that creates the cohesion of the verbal and figurative components of thinking allows students to gain the most thorough understanding the meaning of educational information. This enables students to minimize their cognitive deficiency, elevate scientific mind, and promote

Full Text Available Spanish articulatory phonetics, the classification of sounds and the physiological mechanism used in the production of phonemes are discussed in this article. The process of learning a language consists of classifying sounds within the target language. Since the learner may be hearing the utterance in a different way than the native speaker some objective criteria are needed to classify sounds. If these distinctions are not mastered, he may be perceived as sounding awkward. Other phonological processes are applied in informal situations due to socio-linguistic factors such as age, social class, and education. Sound deletion in particular phonological environments are not done randomly by the speaker, but by necessity to retain semantic comprehension. Allophonic choices within phonemes make up the dialect for a particular area.
What Models of Verbal Working Memory Can Learn from Phonological Theory: Decomposing the Phonological Similarity Effect
Schweppe, Judith; Grice, Martine; Rummer, Ralf
Despite developments in phonology over the last few decades, models of verbal working memory make reference to phoneme-sized phonological units, rather than to the features of which they are composed. This study investigates the influence on short-term retention of such features by comparing the serial recall of lists of syllables with varying…
Suppression effects on musical and verbal memory.
Schendel, Zachary A; Palmer, Caroline
Three experiments contrasted the effects of articulatory suppression on recognition memory for musical and verbal sequences. In Experiment 1, a standard/comparison task was employed, with digit or note sequences presented visually or auditorily while participants remained silent or produced intermittent verbal suppression (saying "the") or musical suppression (singing "la"). Both suppression types decreased performance by equivalent amounts, as compared with no suppression. Recognition accuracy was lower during suppression for visually presented digits than during that for auditorily presented digits (consistent with phonological loop predictions), whereas accuracy was equivalent for visually presented notes and auditory tones. When visual interference filled the retention interval in Experiment 2, performance with visually presented notes but not digits was impaired. Experiment 3 forced participants to translate visually presented music sequences by presenting comparison sequences auditorily. Suppression effects for visually presented music resembled those for digits only when the recognition task required sensory translation of cues.
Phonological complexity and prosodic structure in assessment of Serbian phonological development
Directory of Open Access Journals (Sweden)
Nevena Buđevac
Full Text Available In this research we investigate the relevance of phonological parameters in acquisition of Serbian language. Implementation of British Test of Phonological Screeing (TOPhS, van der Lely and Harris, 1999 has revealed that phonological complexity (syllabic and metrical structure influences accuracy in non-word repetition task and could be used in assessment of phonological development of typically developing children, as well as of children with Grammatical Specific Language Impairment (G-SLI (van der Lely and Harris, 1999; Gallon, Harris & van der Lely, 2007. Having in mind phonological properties of Serbian language (Zec, 2000, 2007, we hypothesized that several parameters can be used in assessment of phonological development in Serbian: a. onset (consonants cluster at the beginning of syllable; b. rime (consonant at the end of syllable. c. word of three syllables, and d. placement of stressed syllable in a word. Combination of these parameters gave us a list of 96 pseudo words of different levels of complexity. Participants were 14 adults and 30 children from kindergarten divided into three age groups (3, 4 and 5 years. Task for the participants was to loudly repeat every pseudo-word, and their reproduction was recorded. Transcription of their answers and coding of errors allowed us to analyze impact of different parameters on accuracy of phonological reproduction in children of different ages. The results indicate that the ability for reproduction of Serbian phonological properties develops in early preschool period. The most difficult is cluster of consonants at the beginning of syllable, and consonant at the end of syllable. These two parameters are even more difficult for reproduction in three-syllable words or in words that have more then one parameter marked. Placement of stress in a word is acquired even before 3 years. In other words, the results have shown that investigated features could be good indicators in assessment of early
Vocabulary knowledge, phonological representations and phonological sensitivity in Spanish-speaking low-and middle-SES preschoolers
Directory of Open Access Journals (Sweden)
Beatriz Diuk
Full Text Available The aim of this study was to examine the relationships among vocabulary knowledge, phonological representations and phonological sensitivity in 80 Spanish-speaking preschool children from middle- and low-SES families. Significant social class differences were obtained on all tasks except syllable matching. Regression analyses were carried out to test the predictive power of vocabulary knowledge and accuracy of phonological representations on the phonological sensitivity measures. Receptive vocabulary predicted rhyme identification. Syllable matching was predicted by a task tapping accuracy of phonological representations. The fact that rhyme identification was predicted by vocabulary knowledge but syllable matching was predicted by a measure tapping accuracy of phonological representations in both groups suggests that early lexical development sets the stage for the development of the lower levels of phonological sensitivity but identification of smaller units requires more accurate and segmented phonological representations.

Full Text Available The usage-based conception of language is a major tenet in Cognitive Linguistics, but cognitive phonology has not yet been developed sufficiently in this direction. Often, phonemic analysis is carried out at the high level of abstraction of `a language´, disregarding rich patterns of languageinternal variation. This paper first argues that cognitive phonology must aim at a higher degree of descriptive refinement, especially in the direction of social variation. Then it goes on to examine the implications of a usage-based and multi-faceted model for a theoretical discussion of the phoneme as a prototype category.
High-performers use the phonological loop less to process mental arithmetic during working memory tasks.
Otsuka, Yuki; Osaka, Naoyuki
This study investigated the effects of three working memory components-the central executive, phonological loop, and visuospatial sketchpad-on performance differences in complex mental arithmetic between individuals. Using the dual-task method, we examined how performance during two-digit addition was affected by load on the central executive (random tapping condition), phonological loop (articulatory suppression condition), and visuospatial sketchpad (spatial tapping condition) compared to that under no load (control condition) in high- and low-performers of complex mental arithmetic in Experiment 1. Low-performers showed an increase in errors under the random tapping and articulatory suppression conditions, whereas high-performers showed an increase of errors only under the random tapping condition. In Experiment 2, we conducted similar experiments on only the high-performers but used a shorter presentation time of each number. We found the same pattern for performing complex mental arithmetic as seen in Experiment 1. These results indicate that high-performers might reduce their dependence on the phonological loop, because the central executive enables them to choose a strategy in which they use less working memory capacity.
Brain activity during auditory and visual phonological, spatial and simple discrimination tasks.
Salo, Emma; Rinne, Teemu; Salonen, Oili; Alho, Kimmo
We used functional magnetic resonance imaging to measure human brain activity during tasks demanding selective attention to auditory or visual stimuli delivered in concurrent streams. Auditory stimuli were syllables spoken by different voices and occurring in central or peripheral space. Visual stimuli were centrally or more peripherally presented letters in darker or lighter fonts. The participants performed a phonological, spatial or "simple" (speaker-gender or font-shade) discrimination task in either modality. Within each modality, we expected a clear distinction between brain activations related to nonspatial and spatial processing, as reported in previous studies. However, within each modality, different tasks activated largely overlapping areas in modality-specific (auditory and visual) cortices, as well as in the parietal and frontal brain regions. These overlaps may be due to effects of attention common for all three tasks within each modality or interaction of processing task-relevant features and varying task-irrelevant features in the attended-modality stimuli. Nevertheless, brain activations caused by auditory and visual phonological tasks overlapped in the left mid-lateral prefrontal cortex, while those caused by the auditory and visual spatial tasks overlapped in the inferior parietal cortex. These overlapping activations reveal areas of multimodal phonological and spatial processing. There was also some evidence for intermodal attention-related interaction. Most importantly, activity in the superior temporal sulcus elicited by unattended speech sounds was attenuated during the visual phonological task in comparison with the other visual tasks. This effect might be related to suppression of processing irrelevant speech presumably distracting the phonological task involving the letters. Copyright © 2012 Elsevier B.V. All rights reserved.
Phonology in English language teaching an international approach

Phonology in English Language Teaching is an introductory text, specifically directed at the needs of language teachers internationally. Combining an overview of English phonology with structured practical guidance, this text shows how phonology can be applied in the classroom.An introductory chapter provides the philosophical framework, followed by separate chapters on the phonology of consonants, vowels and prosody. As well as presenting core material on English phonology, the book explores the relationship of orthography to the English sound system from a historical and a pre
Phonological Planning during Sentence Production: Beyond the Verb.
Schnur, Tatiana T
The current study addresses the extent of phonological planning during spontaneous sentence production. Previous work shows that at articulation, phonological encoding occurs for entire phrases, but encoding beyond the initial phrase may be due to the syntactic relevance of the verb in planning the utterance. I conducted three experiments to investigate whether phonological planning crosses multiple grammatical phrase boundaries (as defined by the number of lexical heads of phrase) within a single phonological phrase. Using the picture-word interference paradigm, I found in two separate experiments a significant phonological facilitation effect to both the verb and noun of sentences like "He opens the gate." I also altered the frequency of the direct object and found longer utterance initiation times for sentences ending with a low-frequency vs. high-frequency object offering further support that the direct object was phonologically encoded at the time of utterance initiation. That phonological information for post-verbal elements was activated suggests that the grammatical importance of the verb does not restrict the extent of phonological planning. These results suggest that the phonological phrase is unit of planning, where all elements within a phonological phrase are encoded before articulation. Thus, consistent with other action sequencing behavior, there is significant phonological planning ahead in sentence production.
Grammatical constraints on phonological encoding in speech production.
Heller, Jordana R; Goldrick, Matthew
To better understand the influence of grammatical encoding on the retrieval and encoding of phonological word-form information during speech production, we examine how grammatical class constraints influence the activation of phonological neighbors (words phonologically related to the target--e.g., MOON, TWO for target TUNE). Specifically, we compare how neighbors that share a target's grammatical category (here, nouns) influence its planning and retrieval, assessed by picture naming latencies, and phonetic encoding, assessed by word productions in picture names, when grammatical constraints are strong (in sentence contexts) versus weak (bare naming). Within-category (noun) neighbors influenced planning time and phonetic encoding more strongly in sentence contexts. This suggests that grammatical encoding constrains phonological processing; the influence of phonological neighbors is grammatically dependent. Moreover, effects on planning times could not fully account for phonetic effects, suggesting that phonological interaction affects articulation after speech onset. These results support production theories integrating grammatical, phonological, and phonetic processes.

Modulation of Brain Activity during Phonological Familiarization
Majerus, S.; Van der Linden, M.; Collette, F.; Laureys, S.; Poncelet, M.; Degueldre, C.; Delfiore, G.; Luxen, A.; Salmon, E.
We measured brain activity in 12 adults for the repetition of auditorily presented words and nonwords, before and after repeated exposure to their phonological form. The nonword phoneme combinations were either of high (HF) or low (LF) phonotactic frequency. After familiarization, we observed, for both word and nonword conditions, decreased…
Phonological and conceptual activation in speech comprehension

[Intervention in dyslexic disorders: phonological awareness training].
Etchepareborda, M C
Taking into account the systems for the treatment of brain information when drawing up a work plan allows us to recreate processing routines that go from multisensory perception to motor, oral and cognitive production, which is the step prior to executive levels of thought, bottom-up and top-down processing systems. In recent years, the use of phonological methods to prevent or resolve reading disorders has become the fundamental mainstay in the treatment of dyslexia. The work is mainly based on phonological proficiency, which enables the patient to detect phonemes (input), to think about them (performance) and to use them to build words (output). Daily work with rhymes, the capacity to listen, the identification of phrases and words, and handling syllables and phonemes allows us to perform a preventive intervention that enhances the capacity to identify letters, phonological analysis and the reading of single words. We present the different therapeutic models that are most frequently employed. Fast For Word (FFW) training helps make progress in phonematic awareness and other linguistic skills, such as phonological awareness, semantics, syntax, grammar, working memory and event sequencing. With Deco-Fon, a programme for training phonological decoding, work is carried out on the auditory discrimination of pure tones, letters and consonant clusters, auditory processing speed, auditory and phonematic memory, and graphophonological processing, which is fundamental for speech, language and reading writing disorders. Hamlet is a programme based on categorisation activities for working on phonological conceptualisation. It attempts to encourage the analysis of the segments of words, syllables or phonemes, and the classification of a certain segment as belonging or not to a particular phonological or orthographical category. Therapeutic approaches in the early phases of reading are oriented towards two poles based on the basic mechanisms underlying the process of learning
Time course analyses of orthographic and phonological priming effects during word recognition in a transparent orthography.
Zeguers, M H T; Snellings, P; Huizenga, H M; van der Molen, M W
In opaque orthographies, the activation of orthographic and phonological codes follows distinct time courses during visual word recognition. However, it is unclear how orthography and phonology are accessed in more transparent orthographies. Therefore, we conducted time course analyses of masked priming effects in the transparent Dutch orthography. The first study used targets with small phonological differences between phonological and orthographic primes, which are typical in transparent orthographies. Results showed consistent orthographic priming effects, yet phonological priming effects were absent. The second study explicitly manipulated the strength of the phonological difference and revealed that both orthographic and phonological priming effects became identifiable when phonological differences were strong enough. This suggests that, similar to opaque orthographies, strong phonological differences are a prerequisite to separate orthographic and phonological priming effects in transparent orthographies. Orthographic and phonological priming appeared to follow distinct time courses, with orthographic codes being quickly translated into phonological codes and phonology dominating the remainder of the lexical access phase.
Pitch discrimination associated with phonological awareness: Evidence from congenital amusia.
Sun, Yanan; Lu, Xuejing; Ho, Hao Tam; Thompson, William Forde
Research suggests that musical skills are associated with phonological abilities. To further investigate this association, we examined whether phonological impairments are evident in individuals with poor music abilities. Twenty individuals with congenital amusia and 20 matched controls were assessed on a pure-tone pitch discrimination task, a rhythm discrimination task, and four phonological tests. Amusic participants showed deficits in discriminating pitch and discriminating rhythmic patterns that involve a regular beat. At a group level, these individuals performed similarly to controls on all phonological tests. However, eight amusics with severe pitch impairment, as identified by the pitch discrimination task, exhibited significantly worse performance than all other participants in phonological awareness. A hierarchical regression analysis indicated that pitch discrimination thresholds predicted phonological awareness beyond that predicted by phonological short-term memory and rhythm discrimination. In contrast, our rhythm discrimination task did not predict phonological awareness beyond that predicted by pitch discrimination thresholds. These findings suggest that accurate pitch discrimination is critical for phonological processing. We propose that deficits in early-stage pitch discrimination may be associated with impaired phonological awareness and we discuss the shared role of pitch discrimination for processing music and speech.

Full Text Available Introduction: Treatment of phonological disorders considering extra-linguistic and linguistic variables are important to ensure that the alteration is resolved promptly and in the best manner as possible. Aim: To analyze therapeutic advances (phonetic inventory, phonological system, and distinctive features in children with phonological disorders by considering the therapeutic approach used, the severity of the phonological disorder, age, and the number of therapeutic sessions. Methods: We conducted a case series study of 94 children aged 3 years, 9 months through 8 years, 5 months. The children were divided into groups based on the therapeutic approach used (Modified Cycles, Maximal Oppositions, ABAB-Withdrawal, and Multiple Probes, the severity of their phonological disorder, age, and the number of therapy sessions with each individual. Phonetic inventory, the phonological system, and the number of altered distinctive features were analyzed. Results: The greater the number of therapy sessions, the greater the number of sounds acquired. The number of sounds present in the phonetic inventory and phonological system increased and the severity of the phonological disorder decreased with all of the therapeutic approaches studied. There was also a reduction in the incidence of altered distinctive features. Conclusion: There was a favorable evolution in phonetic inventory and phonological system acquisitions as well as a reduction in the number of altered distinctive features for all 3 therapeutic models regardless of the severity of the phonological disorder, age, or number of sessions.
A consumer guide to phonological evidence

Full Text Available Modern phonological theory is confronted with a wealth of new data from many different sources. This paper gives a summary and taxonomy of the kinds of evidence we currently have at our disposal. For each type it briefly discusses how it has been used, and gives some of the advantages and disadvantages. The main distinction made is between 'existing' data and 'invented' data, even though it is shown that such distinctions should be considered very carefully. I argue that each type of data can have a function in phonological argumentation, but also that each type of data has some very specific problems. The best evidence is converging evidence from different sources.
Phonological similarity in working memory span tasks.
Chow, Michael; Macnamara, Brooke N; Conway, Andrew R A
In a series of four experiments, we explored what conditions are sufficient to produce a phonological similarity facilitation effect in working memory span tasks. By using the same set of memoranda, but differing the secondary-task requirements across experiments, we showed that a phonological similarity facilitation effect is dependent upon the semantic relationship between the memoranda and the secondary-task stimuli, and is robust to changes in the representation, ordering, and pool size of the secondary-task stimuli. These findings are consistent with interference accounts of memory (Brown, Neath, & Chater, Psychological Review, 114, 539-576, 2007; Oberauer, Lewandowsky, Farrell, Jarrold, & Greaves, Psychonomic Bulletin & Review, 19, 779-819, 2012), whereby rhyming stimuli provide a form of categorical similarity that allows distractors to be excluded from retrieval at recall.
Breaking a habit: a further role of the phonological loop in action control.
Saeki, Erina; Baddeley, Alan D; Hitch, Graham J; Saito, Satoru
Recent research has suggested that keeping track of a task goal in rapid task switching may depend on the phonological loop component of working memory. In this study, we investigated whether the phonological loop plays a similar role when a single switch extending over several trials is required after many trials on which one has performed a competing task. Participants were shown pairs of digits varying in numerical and physical size, and they were required to decide which digit was numerically or physically larger. An experimental cycle consisted of four blocks of 24 trials. In Experiment 1, participants in the task change groups performed the numerical-size judgment task during the first three blocks, and then changed to the physical-size judgment task in the fourth. Participants in the continuation groups performed only the physical-size judgment task throughout all four blocks. We found negative effects of articulatory suppression on the fourth block, but only in the task change groups. Experiment 2 was a replication, with the modification that both groups received identical instructions and practice. Experiment 3 was a further replication using numerical-size judgment as the target task. The results showed a pattern similar to that from Experiment 1, with negative effects of articulatory suppression found only in the task change group. The congruity of numerical and physical size had a reliable effect on performance in all three experiments, but unlike the task change, it did not reliably interact with articulatory suppression. The results suggest that in addition to its well-established role in rapid task switching, the phonological loop also contributes to active goal maintenance in longer-term action control.
Phonological similarity and orthographic similarity affect probed serial recall of Chinese characters.
Lin, Yi-Chen; Chen, Hsiang-Yu; Lai, Yvonne C; Wu, Denise H
The previous literature on working memory (WM) has indicated that verbal materials are dominantly retained in phonological representations, whereas other linguistic information (e.g., orthography, semantics) only contributes to verbal WM minimally, if not negligibly. Although accumulating evidence has suggested that multiple linguistic components jointly support verbal WM, the visual/orthographic contribution has rarely been addressed in alphabetic languages, possibly due to the difficulty of dissociating the effects of word forms from the effects of their pronunciations in relatively shallow orthography. In the present study, we examined whether the orthographic representations of Chinese characters support the retention of verbal materials in this language of deep orthography. In Experiments 1a and 2, we independently manipulated the phonological and orthographic similarity of horizontal and vertical characters, respectively, and found that participants' accuracy of probed serial recall was reduced by both similar pronunciations and shared phonetic radicals in the to-be-remembered stimuli. Moreover, Experiment 1b showed that only the effect of phonological, but not that of orthographic, similarity was affected by concurrent articulatory suppression. Taken together, the present results indicate the indispensable contribution of orthographic representations to verbal WM of Chinese characters, and suggest that the linguistic characteristics of a specific language not only determine long-term linguistic-processing mechanisms, but also delineate the organization of verbal WM for that language.
The phonological mistake and 5D paradigm

Piero Crispiani
Full Text Available In the first part of this article I present a background in scientific studies on dyslexia, from cognitive science to the neuropedagogical perspective. In this investigation the analysis of mental processes is the most important thanks to comparison with genetic research. In the second part, the dyslexic condition is seen from the perspective of the neuro-motor approach, named the Praxic Motor Theory, which improves neural circuits and inter-hemispherical exchange, electrical transmission and evoked potentials. In this perspective, the dyslexia condition is a disorder related to lack of coordination, including disorganization in space-time and lateral dominance. The phonological hypothesis referring to a lack of sign-sound association in dyslexia is inappropriate, as the term phonology has been intended in English literature as a more complex process and not simply an association between phoneme and grapheme. It is related to access to the word, groups of sounds, rather than single sounds. In this sense the dyslexic reader does not make a phonological mistake in terms of association, but a kinetic-motor one, in space-time from left to right.
A phonology-free mobile communication app.
Kondapalli, Ananya; Zhang, Lee R; Patel, Shreya; Han, Xiao; Kim, Hee Jin; Li, Xintong; Altschuler, Eric L
Aphasia - loss of comprehension or expression of language - is a devastating functional sequela of stroke. There are as yet no effective methods for rehabilitation of aphasia. An assistive device that allows aphasia patients to communicate and interact at speeds approaching real time is urgently needed. Behavioral and linguistic studies of aphasia patients show that they retain normal thinking processes and most aspects of language. They lack only phonology: the ability to translate (input) and/or output sounds (or written words) such as "ta-ble" into the image of a four-legged object with a top at which one works or eats. We have made a phonology-free communication mobile app that may be useful for patients with aphasia and other communication disorders. Particular innovations of our app include calling Google Images as a "subroutine" to allow a near-infinite number of choices (e.g. food or clothing items) for patients without having to make countless images, and by the use of animation for words, phrases or concepts that cannot be represented by a single image. We have tested our app successfully in one patient. The app may be of great benefit to patients with aphasia and other communication disorders. Implications for Rehabilitation We have made a phonology-free mobile communication app. This app may facilitate communication for patients with aphasia and other communication disorders.
Phonological reduplication in sign language: rules rule
Directory of Open Access Journals (Sweden)
Iris eBerent
Full Text Available Productivity—the hallmark of linguistic competence—is typically attributed to algebraic rules that support broad generalizations. Past research on spoken language has documented such generalizations in both adults and infants. But whether algebraic rules form part of the linguistic competence of signers remains unknown. To address this question, here we gauge the generalization afforded by American Sign Language (ASL. As a case study, we examine reduplication (X→XX—a rule that, inter alia, generates ASL nouns from verbs. If signers encode this rule, then they should freely extend it to novel syllables, including ones with features that are unattested in ASL. And since reduplicated disyllables are preferred in ASL, such rule should favor novel reduplicated signs. Novel reduplicated signs should thus be preferred to nonreduplicative controls (in rating, and consequently, such stimuli should also be harder to classify as nonsigns (in the lexical decision task. The results of four experiments support this prediction. These findings suggest that the phonological knowledge of signers includes powerful algebraic rules. The convergence between these conclusions and previous evidence for phonological rules in spoken language suggests that the architecture of the phonological mind is partly amodal.

Full Text Available Experimental work has established that when subjects judge the phonological wellformedness of nonsense forms, they are strongly affected by the frequency of the phonological elements of the form and by the number of actual words that such a form is similar to. These results challenge phonological theory by suggesting a central role for frequency and the lexicon. In this paper, I review these results and show how they can be easily modelled with Probabilistic Optimality Theory. The payoff is that from very few phonological assumptions we can derive virtually the whole panoply of experimental effects. We can also derive various Local Conjunction effects as well.

Gift Mheta
Full Text Available Abstract: This article analyses the phonological characteristics of Shona musical terms borrowed from English. It discusses the phonological processes that take place when words are borrowed directly or indi-rectly from English. Essentially, the article analyses the adoption and adaptation of Shona loan-words at phonological level. It draws examples from the dictionary of Shona musical terms Duramazwi reMimhanzi (2005. This exploration of loan-word adaptation enhances the understanding of the phonological changes that the musical terms undergo during the borrowing process.
Expressive vocabulary of children with normal and deviant phonological development.
Athayde, Marcia de Lima; Mota, Helena Bolli; Mezzomo, Carolina Lisbôa
expressive vocabulary of children with normal and deviant phonological development. to determine whether alterations presented by children with phonological disorders occur only at the phonological level or if there are any impacts on lexical acquisition; to compare the vocabulary performance of children with phonological disorders to reference values presented by the used test. participants of the study were 36 children of both genders, 14 with phonological disorders (Study group) and 22 with typical language development (Control Group). The ABFW - Vocabulary Test (Befi-Lopes, 2000) was used for assessing the expressive vocabulary of children and later to compare the performance of both groups. the performance of children with phonological disorder in the expressive vocabulary test is similar to that of children with normal phonological development. Most of the children of both groups reached the benchmarks proposed by the test for the different semantic fields. The semantic field Places demonstrated to be the most complex for both groups. the alterations presented by children with phonological disorder area limited to the phonological level, having no impact on the lexical aspect of language.
Phonetic and phonological imitation of intonation in two varieties of Italian
Directory of Open Access Journals (Sweden)
Mariapaola eD'Imperio
Full Text Available The aim of this study was to test whether both phonetic and phonological representations of intonation can be rapidly modified when imitating utterances belonging to a different regional variety of the same language. Our main hypothesis was that tonal alignment, just as other phonetic features of speech, would be rapidly modified by Italian speakers when imitating pitch accents of a different (Southern variety of Italian. In particular, we tested whether Bari Italian speakers would produce later peaks for their native rising L+H* (question pitch accent in the process of imitating Neapolitan Italian rising L*+H accents. Also, we tested whether BI speakers are able to modify other phonetic properties (pitch level as well as phonological characteristics (changes in tonal composition of the same contour. In a follow-up study, we tested if the reverse was also true, i.e. whether NI speakers would produce earlier peaks within the L*+H accent in the process of imitating the L+H* of BI questions, despite the presence of a contrast between two rising accents in this variety. Our results show that phonetic detail of tonal alignment can be successfully modified by both BI and NI speakers when imitating a model speaker of the other variety. The hypothesis of a selective imitation process preventing alignment modifications in NI was hence not supported. Moreover the effect was significantly stronger for low frequency words. Participants were also able to imitate other phonetic cues, in that they modified global utterance pitch level. Concerning phonological convergence, speakers modified the tonal specification of the edge tones in order to resemble that of the other variety by either suppressing or increasing the presence of a final H%. Hence, our data show that intonation imitation leads to fast modification of both phonetic and phonological intonation representations including detail of tonal alignment and pitch scaling.
Phonological short-term store impairment after cerebellar lesion: a single case study.
Chiricozzi, Francesca R; Clausi, Silvia; Molinari, Marco; Leggio, Maria G
The cerebellum is a recent addition to the growing list of cerebral areas involved in the multifaceted structural system that sustains verbal working memory (vWM), but its contribution is still a matter of debate. Here, we present a patient with a selective deficit of vWM resulting from a bilateral cerebellar ischemic lesion. After this acute event, the patient had impaired immediate and delayed word-serial recall and auditory-verbal delayed recognition. The digit span, however, was completely preserved. To investigate the cerebellar contribution to vWM, four experiments addressing the function of different vWM phonological loop components were performed 18 months after the lesion, and results were compared with normative data or, when needed, with a small group of matched controls. In Experiment 1, digit span was assessed with different presentation and response modalities using lists of digits of varying lengths. In Experiment 2, the articulatory rehearsal system was analyzed by measurement of word length and articulatory suppression effects. Experiment 3 was devoted to analyzing the phonological short-term store (ph-STS) by the recency effect, the phonological similarity effect, short-term forgetting, and unattended speech. Data suggested a possible key role of the semantic component of the processed material, which was tested in Experiment 4, in which word and nonword-serial recall with or without interpolating activity were analyzed. The patient showed noticeably reduced scores in the tasks that primarily or exclusively engaged activity of the ph-STS, namely those of Experiment 3, and good performance in the tests that investigated the recirculation of verbal information. This pattern of results implicates the ph-STS as the cognitive locus of the patient's deficit. This report demonstrates a cerebellar role in encoding and/or strengthening the phonological traces in vWM.
Local and global recoding methods for anonymizing set-valued data
Terrovitis, Manolis
In this paper, we study the problem of protecting privacy in the publication of set-valued data. Consider a collection of supermarket transactions that contains detailed information about items bought together by individuals. Even after removing all personal characteristics of the buyer, which can serve as links to his identity, the publication of such data is still subject to privacy attacks from adversaries who have partial knowledge about the set. Unlike most previous works, we do not distinguish data as sensitive and non-sensitive, but we consider them both as potential quasi-identifiers and potential sensitive data, depending on the knowledge of the adversary. We define a new version of the k-anonymity guarantee, the k m-anonymity, to limit the effects of the data dimensionality, and we propose efficient algorithms to transform the database. Our anonymization model relies on generalization instead of suppression, which is the most common practice in related works on such data. We develop an algorithm that finds the optimal solution, however, at a high cost that makes it inapplicable for large, realistic problems. Then, we propose a greedy heuristic, which performs generalizations in an Apriori, level-wise fashion. The heuristic scales much better and in most of the cases finds a solution close to the optimal. Finally, we investigate the application of techniques that partition the database and perform anonymization locally, aiming at the reduction of the memory consumption and further scalability. A thorough experimental evaluation with real datasets shows that a vertical partitioning approach achieves excellent results in practice. © 2010 Springer-Verlag.
[Processing acoustically presented time intervals of seconds duration: an expression of the phonological loop of the working memory?].
Grube, D
Working memory has been proposed to contribute to the processing of time, rhythm and music; the question which component of working memory is involved is under discussion. The present study tests the hypothesis that the phonological loop component (Baddeley, 1986) is involved in the processing of auditorily presented time intervals of a few seconds' duration. Typical effects well known with short-term retention of verbal material could be replicated with short-term retention of temporal intervals: The immediate reproduction of time intervals was impaired under conditions of background music and articulatory suppression. Neither the accuracy nor the speed of responses in a (non-phonological) mental rotation task were diminished under these conditions. Processing of auditorily presented time intervals seems to be constrained by the capacity of the phonological loop: The immediate serial recall of sequences of time intervals was shown to be related to the immediate serial recall of words (memory span). The results confirm the notion that working memory resources, and especially the phonological loop component, underlie the processing of auditorily presented temporal information with a duration of a few seconds.

Phonological decisions require both the left and right supramarginal gyri.
Hartwigsen, Gesa; Baumgaertner, Annette; Price, Cathy J; Koehnke, Maria; Ulmer, Stephan; Siebner, Hartwig R
Recent functional imaging studies demonstrated that both the left and right supramarginal gyri (SMG) are activated when healthy right-handed subjects make phonological word decisions. However, lesion studies typically report difficulties with phonological processing after left rather than right hemisphere damage. Here, we used a unique dual-site transcranial magnetic stimulation (TMS) approach to test whether the SMG in the right hemisphere contributes to modality-independent (i.e., auditory and visual) phonological decisions. To test task-specificity, we compared the effect of real or sham TMS during phonological, semantic, and perceptual decisions. To test laterality and anatomical specificity, we compared the effect of TMS over the left, right, or bilateral SMG and angular gyri. The accuracy and reaction times of phonological decisions were selectively disrupted relative to semantic and perceptual decisions when real TMS was applied over the left, right, or bilateral SMG. These effects were not observed for TMS over the angular gyri. A follow-up experiment indicated that the threshold-intensity for inducing a disruptive effect on phonological decisions was identical for unilateral TMS over the right or left SMG. Taken together, these findings provide converging evidence that the right SMG contributes to accurate and efficient phonological decisions in the healthy brain, with no evidence that the left and right SMG can compensate for one another during TMS. Our findings motivate detailed studies of phonological processing in patients with acute or long-term damage of the right SMG.
Enhancement of Phonological Memory Following Transcranial Magnetic Stimulation (TMS
Directory of Open Access Journals (Sweden)
Matthew P. Kirschen
Full Text Available Phonologically similar items (mell, rell, gell are more difficult to remember than dissimilar items (shen, floy, stap, likely because of mutual interference of the items in the phonological store. Low-frequency transcranial magnetic stimulation (TMS, guided by functional magnetic resonance imaging (fMRI was used to disrupt this phonological confusion by stimulation of the left inferior parietal (LIP lobule. Subjects received TMS or placebo stimulation while remembering sets of phonologically similar or dissimilar pseudo-words. Consistent with behavioral performance of patients with neurological damage, memory for phonologically similar, but not dissimilar, items was enhanced following TMS relative to placebo stimulation. Stimulation of a control region of the brain did not produce any changes in memory performance. These results provide new insights into how the brain processes verbal information by establishing the necessity of the inferior parietal region for optimal phonological storage. A mechanism is proposed for how TMS reduces phonological confusion and leads to facilitation of phonological memory.

Phonological and semantic processing during comprehension in Wernicke's aphasia: An N400 and Phonological Mapping Negativity Study.
Robson, Holly; Pilkington, Emma; Evans, Louise; DeLuca, Vincent; Keidel, James L
Comprehension impairments in Wernicke's aphasia are thought to result from a combination of impaired phonological and semantic processes. However, the relationship between these cognitive processes and language comprehension has only been inferred through offline neuropsychological tasks. This study used ERPs to investigate phonological and semantic processing during online single word comprehension. EEG was recorded in a group of Wernicke's aphasia n=8 and control participants n=10 while performing a word-picture verification task. The N400 and Phonological Mapping Negativity/Phonological Mismatch Negativity (PMN) event-related potential components were investigated as an index of semantic and phonological processing, respectively. Individuals with Wernicke's aphasia displayed reduced and inconsistent N400 and PMN effects in comparison to control participants. Reduced N400 effects in the WA group were simulated in the control group by artificially degrading speech perception. Correlation analyses in the Wernicke's aphasia group found that PMN but not N400 amplitude was associated with behavioural word-picture verification performance. The results confirm impairments at both phonological and semantic stages of comprehension in Wernicke's aphasia. However, reduced N400 responses in Wernicke's aphasia are at least partially attributable to earlier phonological processing impairments. The results provide further support for the traditional model of Wernicke's aphasia which claims a causative link between phonological processing and language comprehension impairments.

Type-specific proactive interference in patients with semantic and phonological STM deficits.
Harris, Lara; Olson, Andrew; Humphreys, Glyn
Prior neuropsychological evidence suggests that semantic and phonological components of short-term memory (STM) are functionally and neurologically distinct. The current paper examines proactive interference (PI) from semantic and phonological information in two STM-impaired patients, DS (semantic STM deficit) and AK (phonological STM deficit). In Experiment 1 probe recognition tasks with open and closed sets of stimuli were used. Phonological PI was assessed using nonword items, and semantic and phonological PI was assessed using words. In Experiment 2 phonological and semantic PI was elicited by an item recognition probe test with stimuli that bore phonological and semantic relations to the probes. The data suggested heightened phonological PI for the semantic STM patient, and exaggerated effects of semantic PI in the phonological STM case. The findings are consistent with an account of extremely rapid decay of activated type-specific representations in cases of severely impaired phonological and semantic STM.
Lexical and metaphonological abilities in preschoolers with phonological disorders.
Costa, Ranilde Cristiane Cavalcante; Avila, Clara Regina Brandão de
lexical and metaphonological abilities of phonologically disordered preschoolers. to investigate the influence of Phonological Disorder on the lexical and metaphonological abilities of a group of preschoolers and the correlation between them. participants were 56 preschoolers - 32 boys and 24 girls - with ages between 4 years and 6 months and 6 years and 11 months, divided into two different groups: the Research Group, composed of 28 preschoolers with Phonological Disorder, and the Control Group, composed of 28 preschoolers with normal speech and no oral speech-related complaints, paired to the research group by gender and age. All of the participants were initially assessed by the ABFW Test - Phonology. After that, they were assessed on their lexical and metaphonological abilities by the ABFW Test - Vocabulary and phonological awareness test: sequential assessment instrument, CONFIAS - identification tasks and, rhyme and alliteration production, respectively. regarding lexical ability, the preschoolers from both groups presented similar behavior. The disordered preschoolers presented the worst performance on the overall analysis of the metaphonological ability. Age had an influence on the performance of lexical ability for both groups and the metaphonological abilities only for the Control Group. Correlations were identified, mostly positive, good to moderate between lexical and metaphonological abilities. the influence of Phonological Disorder may only be observed on the metaphonological performance. Phonological Disorder did not interfere with the development of the lexical ability of this group of preschoolers. Positive correlations were identified between both abilities in the studied age group.
Lateralized frontal activity for Japanese phonological processing during child development
Directory of Open Access Journals (Sweden)
Takaaki eGoto
Full Text Available Phonological awareness is essential for reading, and is common to all language systems, including alphabetic languages and Japanese. This cognitive factor develops during childhood, and is thought to be associated with shifts in brain activity. However, the nature of this neurobiological developmental shift is unclear for speakers of Japanese, which is not an alphabetical language. The present study aimed to reveal a shift in brain functions for processing phonological information in native-born Japanese children. We conducted a phonological awareness task and examined hemodynamic activity in 103 children aged 7 to 12 years. While younger children made mistakes and needed more time to sort phonological information in reverse order, older children completed the task quickly and accurately. Additionally, younger children exhibited increased activity in the bilateral dorsolateral prefrontal cortex, which may be evidence of immature phonological processing skills. Older children exhibited dominant activity in the left compared with the right dorsolateral prefrontal cortex, suggesting that they had already acquired phonological processing skills. We also found significant effects of age and lateralized activity on behavioral performance. During earlier stages of development, the degree of left lateralization appears to have a smaller effect on behavioral performance. Conversely, in later stages of development, the degree of left lateralization appears to have a stronger influence on behavioral performance. These initial findings regarding a neurobiological developmental shift in Japanese speakers suggest that common brain regions play a critical role in the development of phonological processing skills among different languages systems, such as Japanese and alphabetical languages.
Is phonology bypassed in normal or dyslexic development?
Pennington, B F; Lefly, D L; Van Orden, G C; Bookman, M O; Smith, S D
A pervasive assumption in most accounts of normal reading and spelling development is that phonological coding is important early in development but is subsequently superseded by faster, orthographic coding which bypasses phonology. We call this assumption, which derives from dual process theory, the developmental bypass hypothesis. The present study tests four specific predictions of the developmental bypass hypothesis by comparing dyslexics and nondyslexics from the same families in a cross-sectional design. The four predictions are: 1) That phonological coding skill develops early in normal readers and soon reaches asymptote, whereas orthographic coding skill has a protracted course of development; 2) that the correlation of adult reading or spelling performance with phonological coding skill is considerably less than the correlation with orthographic coding skill; 3) that dyslexics who are mainly deficient in phonological coding skill should be able to bypass this deficit and eventually close the gap in reading and spelling performance; and 4) that the greatest differences between dyslexics and developmental controls on measures of phonological coding skill should be observed early rather than late in development.None of the four predictions of the developmental bypass hypothesis were upheld. Phonological coding skill continued to develop in nondyslexics until adulthood. It accounted for a substantial (32-53 percent) portion of the variance in reading and spelling performance in adult nondyslexics, whereas orthographic coding skill did not account for a statistically reliable portion of this variance. The dyslexics differed little across age in phonological coding skill, but made linear progress in orthographic coding skill, surpassing spelling-age (SA) controls by adulthood. Nonetheless, they didnot close the gap in reading and spelling performance. Finally, dyslexics were significantly worse than SA (and Reading Age [RA]) controls in phonological coding skill
An Evaluation of Universal Grammar and the Phonological Mind.
Everett, Daniel L
This paper argues against the hypothesis of a "phonological mind" advanced by Berent. It establishes that there is no evidence that phonology is innate and that, in fact, the simplest hypothesis seems to be that phonology is learned like other human abilities. Moreover, the paper fleshes out the original claim of Philip Lieberman that Universal Grammar predicts that not everyone should be able to learn every language, i.e., the opposite of what UG is normally thought to predict. The paper also underscores the problem that the absence of recursion in Pirahã represents for Universal Grammar proposals.
Phonological working memory and FOXP2.
Schulze, Katrin; Vargha-Khadem, Faraneh; Mishkin, Mortimer
The discovery and description of the affected members of the KE family (aKE) initiated research on how genes enable the unique human trait of speech and language. Many aspects of this genetic influence on speech-related cognitive mechanisms are still elusive, e.g. if and how cognitive processes not directly involved in speech production are affected. In the current study we investigated the effect of the FOXP2 mutation on Working Memory (WM). Half the members of the multigenerational KE family have an inherited speech-language disorder, characterised as a verbal and orofacial dyspraxia caused by a mutation of the FOXP2 gene. The core phenotype of the affected KE members (aKE) is a deficiency in repeating words, especially complex non-words, and in coordinating oromotor sequences generally. Execution of oromotor sequences and repetition of phonological sequences both require WM, but to date the aKE's memory ability in this domain has not been examined in detail. To do so we used a test series based on the Baddeley and Hitch WM model, which posits that the central executive (CE), important for planning and manipulating information, works in conjunction with two modality-specific components: The phonological loop (PL), specialized for processing speech-based information; and the visuospatial sketchpad (VSSP), dedicated to processing visual and spatial information. We compared WM performance related to CE, PL, and VSSP function in five aKE and 15 healthy controls (including three unaffected members of the KE family who do not have the FOXP2 mutation). The aKE scored significantly below this control group on the PL component, but not on the VSSP or CE components. Further, the aKE were impaired relative to the controls not only in motor (i.e. articulatory) output but also on the recognition-based PL subtest (word-list matching), which does not require speech production. These results suggest that the aKE's impaired phonological WM may be due to a defect in subvocal
Phonological Processes in Complex and Compound Words

Full Text Available Abstract This research at making a comparison between phonological processes in complex and compound Persian words. Data are gathered from a 40,000-word Persian dictionary. To catch some results, 4,034 complex words and 1,464 compound ones are chosen. To count the data, "excel" software is used. Some results of the research are: 1- "Insertion" is the usual phonological process in complex words. More than half of different insertions belongs to the consonant /g/. Then /y/ and // are in the second and the third order. The consonant /v/ has the least percentage of all. The most percentage of vowel insertion belongs to /e/. The vowels /a/ and /o/ are in the second and third order. Deletion in complex words can only be seen in consonant /t/ and vowel /e/. 2- The most frequent phonological processes in compounds is consonant deletion. In this process, seven different consonants including /t/, //, /m/, /r/, / ǰ/, /d, and /c/. The only deleted vowel is /e/. In both groups of complex and compound, /t/ deletion can be observed. A sequence of three consonants paves the way for the deletion of one of the consonants, if one of the sequences is a sonorant one like /n/, the deletion process rarely happens. 3- In complex words, consonant deletion causes a lighter syllable weight, whereas vowel deletion causes a heavier syllable weight. So, both of the processes lead to bi-moraic weight. 4- The production of bi-moraic syllable in Persian is preferable to Syllable Contact Law. So, Specific Rules have precedence to Universals. 5- Vowel insertion can be seen in both groups of complex and compound words. In complex words, /e/ insertion has the most fundamental part. The vowels /a/ and /o/ are in the second and third place. Whenever there are two sequences of ultra-heavy syllables. By vowel insertion, the first syllable is broken into two light syllables. The compounds that are influenced by vowel insertion, can be and are pronounced without any insertion
Phonological Analysis of University Students' Spoken Discourse

Clara Herlina
Full Text Available The study of discourse is the study of using language in actual use. In this article, the writer is trying to investigate the phonological features, either segmental or supra-segmental, in the spoken discourse of Indonesian university students. The data were taken from the recordings of 15 conversations by 30 students of Bina Nusantara University who are taking English Entrant subject (TOEFL –IBT. Finally, the writer is in opinion that the students are still influenced by their first language in their spoken discourse. This results in English with Indonesian accent. Even though it does not cause misunderstanding at the moment, this may become problematic if they have to communicate in the real world.
Correspondence Theory and Phonological Blending in French
Directory of Open Access Journals (Sweden)
Lee Scott
Full Text Available Though less productive than rival word-formation processes like compounding and affixation, blending is still a rich source of neologisms in French. Despite this productivity, however, blends are often seen by scholars as unpredictable, uninteresting, or both. This analysis picks up where recent studies of blending have left off, using Correspondence Theory and a bundle of segmental constraints to deal with this phenomenon as it pertains to French. More specifically, it shows that blending is the result of a single output standing in correspondence with two or more other outputs, and that we do not need to refer to prosodic information, which is crucial in accounts of blending in languages with lexical stress like English, to account for the process in French. The analysis also differs from previous studies in that it locates blending exclusively within the phonology, leaving its morphological and semantic characteristics to be handled by other processes in the grammar.

Learning general phonological rules from distributional information: a computational model.
Calamaro, Shira; Jarosz, Gaja
Phonological rules create alternations in the phonetic realizations of related words. These rules must be learned by infants in order to identify the phonological inventory, the morphological structure, and the lexicon of a language. Recent work proposes a computational model for the learning of one kind of phonological alternation, allophony (Peperkamp, Le Calvez, Nadal, & Dupoux, 2006). This paper extends the model to account for learning of a broader set of phonological alternations and the formalization of these alternations as general rules. In Experiment 1, we apply the original model to new data in Dutch and demonstrate its limitations in learning nonallophonic rules. In Experiment 2, we extend the model to allow it to learn general rules for alternations that apply to a class of segments. In Experiment 3, the model is further extended to allow for generalization by context; we argue that this generalization must be constrained by linguistic principles.

Phonological competence development in Italian as second/foreign language
Directory of Open Access Journals (Sweden)
Anja Zorman
Full Text Available In language courses and teaching materials for Italian as a second or foreign language little attention is generally paid to the development of phonological competence and of speaking ability. The present study involved 140 pupils of elementary schools with Slovene as the language of instruction in the bilingual area of the Slovene Coastal area where Italian is taught as a second language. The research investigated the impact of phonology teaching and the development of phonological awareness on auditory perception abilities. The findings show that programs for the development of discriminatory listening and phonological segmentation of linguistic input critically influence the pupils' ability of auditory perception, provided such programs are long-term, systematic, intensive, and carried out through direct interaction between the pupils and speakers of the target language. Consequently, such programs also enhance enhance the development of listening comprehension and communicative competence in the target language.
Manipulating stored phonological input during verbal working memory
Cogan, Gregory B.; Iyer, Asha; Melloni, Lucia; Thesen, Thomas; Friedman, Daniel; Doyle, Werner; Devinsky, Orrin; Pesaran, Bijan
Verbal working memory (vWM), involves storing and manipulating information in phonological sensory input. An influential theory of vWM proposes that manipulation is carried out by a central executive while storage is performed by two interacting systems: A phonological input buffer that captures sound-based information and an articulatory rehearsal system that controls speech motor output. Whether, when, and how neural activity in the brain encodes these components remains unknown. Here, we read-out the contents of vWM from neural activity in human subjects as they manipulate stored speech sounds. As predicted, we identify storage systems that contain both phonological sensory and articulatory motor representations. Surprisingly however, we find that manipulation does not involve a single central executive but rather involves two systems with distinct contributions to successful manipulation. We propose, therefore, that multiple subsystems comprise the central executive needed to manipulate stored phonological input for articulatory motor output in vWM. PMID:27941789
Phonological decisions require both the left and right supramarginal gyri
DEFF Research Database (Denmark)
Hartwigsen, Gesa; Baumgaertner, Annette; Price, Cathy J
Recent functional imaging studies demonstrated that both the left and right supramarginal gyri (SMG) are activated when healthy right-handed subjects make phonological word decisions. However, lesion studies typically report difficulties with phonological processing after left rather than right...... the right or left SMG. Taken together, these findings provide converging evidence that the right SMG contributes to accurate and efficient phonological decisions in the healthy brain, with no evidence that the left and right SMG can compensate for one another during TMS. Our findings motivate detailed...... hemisphere damage. Here, we used a unique dual-site transcranial magnetic stimulation (TMS) approach to test whether the SMG in the right hemisphere contributes to modality-independent (i.e., auditory and visual) phonological decisions. To test task-specificity, we compared the effect of real or sham TMS...

Electrophysiological signatures of phonological and semantic maintenance in sentence repetition.
Meltzer, Jed A; Kielar, Aneta; Panamsky, Lilia; Links, Kira A; Deschamps, Tiffany; Leigh, Rosie C
Verbal short-term memory comprises resources for phonological rehearsal, which have been characterized anatomically, and for maintenance of semantic information, which are less understood. Sentence repetition tasks tap both processes interactively. To distinguish brain activity involved in phonological vs. semantic maintenance, we recorded magnetoencephalography during a sentence repetition task, incorporating three manipulations emphasizing one mechanism over the other. Participants heard sentences or word lists and attempted to repeat them verbatim after a 5-second delay. After MEG, participants completed a cued recall task testing how much they remembered of each sentence. Greater semantic engagement relative to phonological rehearsal was hypothesized for 1) sentences vs. word lists, 2) concrete vs. abstract sentences, and 3) well recalled vs. poorly recalled sentences. During auditory perception and the memory delay period, we found highly left-lateralized activation in the form of 8-30 Hz event-related desynchronization. Compared to abstract sentences, concrete sentences recruited posterior temporal cortex bilaterally, demonstrating a neural signature for the engagement of visual imagery in sentence maintenance. Maintenance of arbitrary word lists recruited right hemisphere dorsal regions, reflecting increased demands on phonological rehearsal. Sentences that were ultimately poorly recalled in the post-test also elicited extra right hemisphere activation when they were held in short-term memory, suggesting increased demands on phonological resources. Frontal midline theta oscillations also reflected phonological rather than semantic demand, being increased for word lists and poorly recalled sentences. These findings highlight distinct neural resources for phonological and semantic maintenance, with phonological maintenance associated with stronger oscillatory modulations.

Levels of Phonological Awareness, Working Memory, and Lexical Knowledge in Elementary School Children
Directory of Open Access Journals (Sweden)
Heloisa Helena Motta Bandini
Full Text Available Relationships between oral language, phonological awareness, and working memory have been empirically demonstrated, however, phonological awareness encompasses different abilities, assessed at different levels. The present study investigated the possible associations between specific phonological awareness abilities and phonological working memory in first-grade students. In the initial phase ( n = 254, the study evaluated the abilities of phonological awareness and phonological working memory and found a high positive correlation between these abilities, thus confirming the findings of previous studies. The second phase ( n = 12 evaluated the vocabulary of individuals who, in the initial phase, showed low or high working memory and phonological awareness scores. Students with low working memory and low phonological awareness capacities had low scores in expressive language abilities, suggesting that phonological working memory may have direct effects on lexical knowledge. These results contribute to the understanding of the relationships investigated in this study and have important implications for planning teaching strategies.
Auditory phonological priming in children and adults during word repetition
Cleary, Miranda; Schwartz, Richard G.
Short-term auditory phonological priming effects involve changes in the speed with which words are processed by a listener as a function of recent exposure to other similar-sounding words. Activation of phonological/lexical representations appears to persist beyond the immediate offset of a word, influencing subsequent processing. Priming effects are commonly cited as demonstrating concurrent activation of word/phonological candidates during word identification. Phonological priming is controversial, the direction of effects (facilitating versus slowing) varying with the prime-target relationship. In adults, it has repeatedly been demonstrated, however, that hearing a prime word that rhymes with the following target word (ISI=50 ms) decreases the time necessary to initiate repetition of the target, relative to when the prime and target have no phonemic overlap. Activation of phonological representations in children has not typically been studied using this paradigm, auditory-word + picture-naming tasks being used instead. The present study employed an auditory phonological priming paradigm being developed for use with normal-hearing and hearing-impaired children. Initial results from normal-hearing adults replicate previous reports of faster naming times for targets following a rhyming prime word than for targets following a prime having no phonemes in common. Results from normal-hearing children will also be reported. [Work supported by NIH-NIDCD T32DC000039.
Musical plus phonological input for young foreign language readers.
Fonseca-Mora, M C; Jara-Jiménez, Pilar; Gómez-Domínguez, María
Based on previous studies showing that phonological awareness is related to reading abilities and that music training improves phonological processing, the aim of the present study was to test for the efficiency of a new method for teaching to read in a foreign language. Specifically, we tested the efficacy of a phonological training program, with and without musical support that aimed at improving early reading skills in 7-8-year-old Spanish children (n = 63) learning English as a foreign language. Of interest was also to explore the impact of this training program on working memory and decoding skills. To achieve these goals we tested three groups of children before and after training: a control group, an experimental group with phonological non-musical intervention (active control), and an experimental group with musical intervention. Results clearly point to the beneficial effects of the phonological teaching approach but the further impact of the music support was not demonstrated. Moreover, while children in the music group showed low musical aptitudes before training, they nevertheless performed better than the control group. Therefore, the phonological training program with and without music support seem to have significant effects on early reading skills.
Developmental dyslexia and phonological processing in European Portuguese orthography.
Moura, Octávio; Moreno, Joana; Pereira, Marcelino; Simões, Mário R
This study analysed the performance of phonological processing, the diagnostic accuracy and the influence on reading in children who were native speakers of an orthography of intermediate depth. Portuguese children with developmental dyslexia (DD; N=24; aged 10-12 years), chronological age (CA)-matched controls (N=24; aged 10-12 years) and reading level (RL)-matched controls (N=24; aged 7-9 years) were tested on measures of phonological processing (phonological awareness, naming speed and verbal short-term memory) and reading. The results indicated that the children with DD performed significantly poorer in all measures compared with the CA and RL. Phonological awareness and naming speed showed a high accuracy (receiver operating characteristics curve analysis) for discriminating the children with DD from the CA and RL, whereas the presence of abnormally low scores in phonological awareness and naming speed was more frequent in the DD group than in the controls and the normative population. Hierarchical linear regression analyses revealed that phonological awareness was the most important predictor of all reading accuracy measures, whereas naming speed was particularly related to text reading fluency.

Delivering phonological and phonics training within whole-class teaching.
Shapiro, Laura R; Solity, Jonathan
Early, intensive phonological awareness and phonics training is widely held to be beneficial for children with poor phonological awareness. However, most studies have delivered this training separately from children's normal whole-class reading lessons. We examined whether integrating this training into whole class, mixed-ability reading lessons could impact on children with poor phonological awareness, whilst also benefiting normally developing readers. Teachers delivered the training within a broad reading programme to whole classes of children from Reception to the end of Year 1 (N=251). A comparison group of children received standard teaching methods (N=213). Children's literacy was assessed at the beginning of Reception, and then at the end of each year until 1 year post-intervention. The strategy significantly impacted on reading performance for normally developing readers and those with poor phonological awareness, vastly reducing the incidence of reading difficulties from 20% in comparison schools to 5% in intervention schools. Phonological and phonics training is highly effective for children with poor phonological awareness, even when incorporated into whole-class teaching.
The role of phonology and phonologically related skills in reading instruction for students who are deaf or hard of hearing.
Wang, Ye; Trezek, Beverly J; Luckner, John L; Paul, Peter V
The article challenges educators to rethink reading instruction practices for students who are deaf or hard of hearing. The authors begin with a discussion of the role of phonology in reading, then summarize the evidence of phonological coding among skilled deaf readers and investigate alternative routes for acquiring phonologically related skills such as the use of speechreading, articulatory feedback, Visual Phonics, and Cued Speech. Finally, they present recent intervention studies and proposed procedures to employ phonics-based instruction with students who are deaf or hard of hearing. The authors conclude with the assertion that the teaching of phonologically related skills by means of instructional tools such as Visual Phonics and Cued Speech can and should be incorporated into reading instruction for students who are deaf or hard of hearing. The authors recommend additional research in this important area.
Speech monitoring and phonologically-mediated eye gaze in language perception and production: a comparison using printed word eye-tracking
Gauvin, Hanna S.; Hartsuiker, Robert J.; Huettig, Falk
The Perceptual Loop Theory of speech monitoring assumes that speakers routinely inspect their inner speech. In contrast, Huettig and Hartsuiker (2010) observed that listening to one's own speech during language production drives eye-movements to phonologically related printed words with a similar time-course as listening to someone else's speech does in speech perception experiments. This suggests that speakers use their speech perception system to listen to their own overt speech, but not to their inner speech. However, a direct comparison between production and perception with the same stimuli and participants is lacking so far. The current printed word eye-tracking experiment therefore used a within-subjects design, combining production and perception. Displays showed four words, of which one, the target, either had to be named or was presented auditorily. Accompanying words were phonologically related, semantically related, or unrelated to the target. There were small increases in looks to phonological competitors with a similar time-course in both production and perception. Phonological effects in perception however lasted longer and had a much larger magnitude. We conjecture that this difference is related to a difference in predictability of one's own and someone else's speech, which in turn has consequences for lexical competition in other-perception and possibly suppression of activation in self-perception.

Brain basis of phonological awareness for spoken language in children and its disruption in dyslexia.
Kovelman, Ioulia; Norton, Elizabeth S; Christodoulou, Joanna A; Gaab, Nadine; Lieberman, Daniel A; Triantafyllou, Christina; Wolf, Maryanne; Whitfield-Gabrieli, Susan; Gabrieli, John D E
Phonological awareness, knowledge that speech is composed of syllables and phonemes, is critical for learning to read. Phonological awareness precedes and predicts successful transition from language to literacy, and weakness in phonological awareness is a leading cause of dyslexia, but the brain basis of phonological awareness for spoken language in children is unknown. We used functional magnetic resonance imaging to identify the neural correlates of phonological awareness using an auditory word-rhyming task in children who were typical readers or who had dyslexia (ages 7-13) and a younger group of kindergarteners (ages 5-6). Typically developing children, but not children with dyslexia, recruited left dorsolateral prefrontal cortex (DLPFC) when making explicit phonological judgments. Kindergarteners, who were matched to the older children with dyslexia on standardized tests of phonological awareness, also recruited left DLPFC. Left DLPFC may play a critical role in the development of phonological awareness for spoken language critical for reading and in the etiology of dyslexia.
Individual differences in phonological learning and verbal STM span.
Service, Elisabet; Maury, Sini; Luotoniemi, Emilia
A relationship between phonological short-term memory tasks (e.g., nonword repetition, digit span) and vocabulary learning in both experimental and real-life conditions has been reported in numerous studies. A mechanism that would explain this correlation is, however, not known. The present study explores the possibility that it is the quality of phonological representations that affects both short-term recall and long-term learning of novel wordlike items. In Experiment 1, groups with relatively good and poor span for pseudowords were established. The good group was found to perform better at explicit memory tasks tapping the incidental learning of a limited stimulus pool used in an auditory immediate serial pseudoword recall task. In Experiment 2, the results of Experiment 1 were replicated when experience of correct recall was controlled. In Experiment 3, the immediate recall performance of the good group was found to benefit more than that of the poor group from syllable repetition within stimulus pools. It is concluded that the efficiency of a process that creates phonological representations is related both to short-term capacity for verbal items, and to long-term phonological learning of the structure of novel phonological items.
Morphological processing with deficient phonological short-term memory.
Kavé, Gitit; Ze'ev, Hagit Bar; Lev, Anita
This paper investigates the processing of Hebrew derivational morphology in an individual (S.E.) with deficient phonological short-term memory. In comparison to 10 age- and education-matched men, S.E. was impaired on digit span tasks and demonstrated no recency effect in word list recall. S.E. had low word retention span, but he exhibited phonological similarity and word length effects. His ability to make lexical decisions was intact. In a paired-associate test S.E. successfully learned semantically and morphologically related pairs but not phonologically related pairs, and his learning of nonwords was facilitated by the presence of Hebrew consonant roots. Semantic and morphological similarity enhanced immediate word recall. Results show that S.E. is capable of conducting morphological decomposition of Hebrew-derived words despite his phonological deficit, suggesting that transient maintenance of morphological constituents is independent of temporary storage and rehearsal of phonological codes, and that each is processed separately within short-term memory.
Exploring the variation in implementation of a COPD disease management programme and its impact on health outcomes: a post hoc analysis of the RECODE cluster randomised trial.

This study aims to (1) examine the variation in implementation of a 2-year chronic obstructive pulmonary disease (COPD) management programme called RECODE, (2) analyse the facilitators and barriers to implementation and (3) investigate the influence of this variation on health outcomes. Implementation variation among the 20 primary-care teams was measured directly using a self-developed scale and indirectly through the level of care integration as measured with the Patient Assessment of Chronic Illness Care (PACIC) and the Assessment of Chronic Illness Care (ACIC). Interviews were held to obtain detailed information regarding the facilitators and barriers to implementation. Multilevel models were used to investigate the association between variation in implementation and change in outcomes. The teams implemented, on average, eight of the 19 interventions, and the specific package of interventions varied widely. Important barriers and facilitators of implementation were (in)sufficient motivation of healthcare provider and patient, the high starting level of COPD care, the small size of the COPD population per team, the mild COPD population, practicalities of the information and communication technology (ICT) system, and hurdles in reimbursement. Level of implementation as measured with our own scale and the ACIC was not associated with health outcomes. A higher level of implementation measured with the PACIC was positively associated with improved self-management capabilities, but this association was not found for other outcomes. There was a wide variety in the implementation of RECODE, associated with barriers at individual, social, organisational and societal level. There was little association between extent of implementation and health outcomes.

The objective of this work is to quantify the suppressive imbalance, based on the manipulation of ocular luminance, between a group of subjects with normal binocular vision and a group of subjects with amblyopia. The result reveals that there are statistically significant differences in interocular dominance between two groups, evidencing a greater suppressive imbalance in amblyopic subjects. The technique used, proved to be a simple, easy to apply and economic method, for quantified ocular dominance. It is presented as a technique with the potential to accompany subjects with a marked dominance in one of the eyes that makes fusion difficult.
Semantic and phonological contributions to short-term repetition and long-term cued sentence recall.
Meltzer, Jed A; Rose, Nathan S; Deschamps, Tiffany; Leigh, Rosie C; Panamsky, Lilia; Silberberg, Alexandra; Madani, Noushin; Links, Kira A
The function of verbal short-term memory is supported not only by the phonological loop, but also by semantic resources that may operate on both short and long time scales. Elucidation of the neural underpinnings of these mechanisms requires effective behavioral manipulations that can selectively engage them. We developed a novel cued sentence recall paradigm to assess the effects of two factors on sentence recall accuracy at short-term and long-term stages. Participants initially repeated auditory sentences immediately following a 14-s retention period. After this task was complete, long-term memory for each sentence was probed by a two-word recall cue. The sentences were either concrete (high imageability) or abstract (low imageability), and the initial 14-s retention period was filled with either an undemanding finger-tapping task or a more engaging articulatory suppression task (Exp. 1, counting backward by threes; Exp. 2, repeating a four-syllable nonword). Recall was always better for the concrete sentences. Articulatory suppression reduced accuracy in short-term recall, especially for abstract sentences, but the sentences initially recalled following articulatory suppression were retained better at the subsequent cued-recall test, suggesting that the engagement of semantic mechanisms for short-term retention promoted encoding of the sentence meaning into long-term memory. These results provide a basis for using sentence imageability and subsequent memory performance as probes of semantic engagement in short-term memory for sentences.

All participants improved written language abilities in response to treatment, but one subgroup was limited in their ability to regain phonological skills. Both anterior and posterior components of the perisylvian phonological network were damaged in that group. These findings are consistent with fMRI activation when healthy adults write nonwords, and provide insight regarding neural support necessary for phonological rehabilitation.

This chapter assesses the relationship between phonology and literacy by comparing children at family risk of dyslexia, children with SLI, and typically developing children on preschool phonological measures and literacy and phonological skills at eight years of age. As expected, 37% of the
Phonological Memory and the Acquisition of Grammar in Child L2 Learners
Verhagen, Josje; Leseman, Paul; Messer, Marielle
Previous studies show that second language (L2) learners with large phonological memory spans outperform learners with smaller memory spans on tests of L2 grammar. The current study investigated the relationship between phonological memory and L2 grammar in more detail than has been done earlier. Specifically, we asked how phonological memory…
Phonological Process and Accuracy Measures in Typically Developing Punjabi Speaking Children between 3-5 Years
Kaur, Simran; John, Sunila; Veena, K. D.; Rajashekhar, B.
Phonology is an area of linguistics that is concerned with the sounds of language. Since each language has its own unique system of sound patterns, there is a need to study phonological development in different languages. However, lack of published data necessitates the present study on phonological developmental pattern in Punjabi language…

A case study follows the development of phonologic abilities in a child with Prader-Willi syndrome, during her enrollment in language and phonologic remediation from age 2:7 to 6:1. Changes in her phonetic inventory, in the set of phonemes used correctly, and in phonologic processes are described. (Author/JDD)
Commentary on Baddeley and Larsen (2007). The phonological store abandoned.
Jones, Dylan M; Hughes, Robert W; Macken, William J
Baddeley and Larsen (2007) argue that a number of key findings reported by Jones, Macken, and Nicholls (2004) and Jones, Hughes, and Macken (2006) pointing to shortcomings of the phonological store construct arise from the store being abandoned with long lists. In our rejoinder we point out that Baddeley and Larsen use a procedure in which retrieval from the supposed phonological storage would not--according to their own theory--have been possible, and we present theoretical, empirical, and logical problems with their "store abandonment" argument and highlight a number of difficulties associated with the interpretation of suffix and prefix effects. We conclude that our data are still problematic for the phonological store construct and suggest that a reformulation of short-term memory theory needs to embody (or indeed focus exclusively upon) perceptual and effector systems rather than bespoke storage modules.
Phonology, reading, and Chomsky and Halle's optimal orthography.
Steinberg, D D
Chomsky and Halle claim that an orthography based on their underlying phonological representations (UPR) of lexical items would be optimal for English. This paper challenges three of C & H's basic phonological assumptions, that their vowel shift rule is valid, that the UPR is the only sound representation to be listed in the lexicon, and that derived words do not appear as wholes in the lexicon. A less abstract phonological representation level based on the conscious perceptions of speakers, the surface phonemic (SPR), is proposed. An SPR-based orthography has advantages which a UPR-based orthography would not: it is easy to learn and teach, it can be learned at an early age, and it permits rapid detection of rhyme. It is concluded that an orthography based on SPRs, and not UPRs, would be optimal.
The Basis of the Syllable Hierarchy: Articulatory Pressures or Universal Phonological Constraints?
Zhao, Xu; Berent, Iris
Across languages, certain syllable types are systematically preferred to others (e.g., [Formula: see text] lbif, where [Formula: see text] indicates a preference). Previous research has shown that these preferences are active in the brains of individual speakers, they are evident even when none of these syllable types exists in participants' language, and even when the stimuli are presented in print. These results suggest that the syllable hierarchy cannot be reduced to either lexical or auditory/phonetic pressures. Here, we examine whether the syllable hierarchy is due to articulatory pressures. According to the motor embodiment view, the perception of a linguistic stimulus requires simulating its production; dispreferred syllables (e.g., lbif) are universally disliked because their production is harder to simulate. To address this possibility, we assessed syllable preferences while articulation was mechanically suppressed. Our four experiments each found significant effects of suppression. Remarkably, people remained sensitive to the syllable hierarchy regardless of suppression. Specifically, results with auditory materials (Experiments 1-2) showed strong effects of syllable structure irrespective of suppression. Moreover, syllable structure uniquely accounted for listeners' behavior even when controlling for several phonetic characteristics of our auditory materials. Results with printed stimuli (Experiments 3-4) were more complex, as participants in these experiments relied on both phonological and graphemic information. Nonetheless, readers were sensitive to most of the syllable hierarchy (e.g., [Formula: see text]), and these preferences emerged when articulation was suppressed, and even when the statistical properties of our materials were controlled via a regression analysis. Together, these findings indicate that speakers possess broad grammatical preferences that are irreducible to either sensory or motor factors.

Nathan Badenoch
Full Text Available This paper describes the phonology of the Sida language, a Tibeto-Burman language spoken by approximately 3,900 people in Laos and Vietnam. The data presented here are the variety spoken in Luang Namtha province of northwestern Laos, and focuses on a synchronic description of the fundamentals of the Sida phonological systems. Several issues of diachronic interest are also discussed in the context of the diversity of the Southern Loloish group of languages, many of which are spoken in Laos and have not yet been described in detail.
Rapid extraction of lexical tone phonology in Chinese characters: a visual mismatch negativity study.
Directory of Open Access Journals (Sweden)
Xiao-Dong Wang
Full Text Available BACKGROUND: In alphabetic languages, emerging evidence from behavioral and neuroimaging studies shows the rapid and automatic activation of phonological information in visual word recognition. In the mapping from orthography to phonology, unlike most alphabetic languages in which there is a natural correspondence between the visual and phonological forms, in logographic Chinese, the mapping between visual and phonological forms is rather arbitrary and depends on learning and experience. The issue of whether the phonological information is rapidly and automatically extracted in Chinese characters by the brain has not yet been thoroughly addressed. METHODOLOGY/PRINCIPAL FINDINGS: We continuously presented Chinese characters differing in orthography and meaning to adult native Mandarin Chinese speakers to construct a constant varying visual stream. In the stream, most stimuli were homophones of Chinese characters: The phonological features embedded in these visual characters were the same, including consonants, vowels and the lexical tone. Occasionally, the rule of phonology was randomly violated by characters whose phonological features differed in the lexical tone. CONCLUSIONS/SIGNIFICANCE: We showed that the violation of the lexical tone phonology evoked an early, robust visual response, as revealed by whole-head electrical recordings of the visual mismatch negativity (vMMN, indicating the rapid extraction of phonological information embedded in Chinese characters. Source analysis revealed that the vMMN was involved in neural activations of the visual cortex, suggesting that the visual sensory memory is sensitive to phonological information embedded in visual words at an early processing stage.

English-French bilingual children's phonological awareness and vocabulary skills
Directory of Open Access Journals (Sweden)
PiYu Chiang
Full Text Available Abstract This study examined the relationship between English-speaking children's vocabulary skills in English and in French and their phonological awareness skills in both languages. Forty-four kindergarten-aged children attending French immersion programs were administered a receptive vocabulary test, an expressive vocabulary test and a phonological awareness test in English and French. Results showed that French phonological awareness was largely explained by English phonological awareness, consistent with previous findings that phonological awareness skills transfer across languages. However, there was a small unique contribution from French expressive vocabulary size to French phonological awareness. The importance of vocabulary skills to the development of phonological awareness is discussed.
The role of phonological awareness in reading comprehension
Directory of Open Access Journals (Sweden)
Maria Silvia Cárnio
Full Text Available ABSTRACT Purpose: to characterize the performance of 4th grade-Elementary School students with and without signs of reading and writing disorders as for phonological awareness and reading comprehension, and also verify possible correlations between them. Methods: 60 children enrolled in the 4th grade of Elementary School from two public schools, whose parents signed the Informed Consent Form, participated in the present study. They were selected and organized in groups, with and without signs of reading and writing disorders. All students were individually assessed regarding their phonological awareness and reading comprehension of sentences and texts through standardized tests. The data underwent statistical analysis. Results: those with signs of reading and writing disorders showed the lowest performance in the reading comprehension of sentences and texts. A correlation was found between phonological awareness and reading comprehension of sentences and texts in both groups. Conclusion: students with no signs of reading and writing disorders had a higher performance in the skills assessed. The correlation found between phonological awareness and reading comprehension of sentences and texts shows not only the importance of metaphonological skills for a proficient reading, but also for a comprehensive one.

Finley, Sara
Nonadjacent dependencies are an important part of the structure of language. While the majority of syntactic and phonological processes occur at a local domain, there are several processes that appear to apply at a distance, posing a challenge for theories of linguistic structure. This article addresses one of the most common nonadjacent phenomena in phonology: transparent vowels in vowel harmony. Vowel harmony occurs when adjacent vowels are required to share the same phonological feature value (e.g. V +F C V +F ). However, transparent vowels create a second-order nonadjacent pattern because agreement between two vowels can 'skip' the transparent neutral vowel in addition to consonants (e.g. V +F C V T -F C V +F ). Adults are shown to display initial learning biases against second-order nonadjacency in experiments that use an artificial grammar learning paradigm. Experiments 1-3 show that adult learners fail to learn the second-order long-distance dependency created by the transparent vowel (as compared to a control condition). In experiments 4-5, training in terms of overall exposure as well as the frequency of relevant transparent items was increased. With adequate exposure, learners reliably generalize to novel words containing transparent vowels. The experiments suggest that learners are sensitive to the structure of phonological representations, even when learning occurs at a relatively rapid pace.
Phonological and semantic strategies in immediate serial recall.
Campoy, Guillermo; Baddeley, Alan
It has been suggested that certain theoretically important anomalous results in the area of verbal short-term memory could be attributable to differences in strategy. However there are relatively few studies that investigate strategy directly. We describe four experiments, each involving the immediate serial recall of word sequences under baseline control conditions, or preceded by instruction to use a phonological or semantic strategy. Two experiments varied phonological similarity at a presentation rate of one item every 1 or 2 seconds. Both the control and the phonologically instructed group showed clear effects of similarity at both presentation rates, whereas these were largely absent under semantic encoding conditions. Two further experiments manipulated word length at the same two rates. The phonologically instructed groups showed clear effects at both rates, the control group showed a clear effect at the rapid rate which diminished with the slower presentation, while the semantically instructed group showed a relatively weak effect at the rate of one item per second, and a significant reverse effect with slower presentation. The latter finding is interpreted in terms of fortuitous differences in inter-item rated associability between the two otherwise matched word pools, reinforcing our conclusion that the semantically instructed group were indeed encoding semantically. Implications for controlling strategy by instruction are discussed.

A Brief Critique of Chomsky's Challenge to Classical Phonemic Phonology.
Liu, Ngar-Fun
Phonemic phonology became important because it provided a descriptive account of dialects and languages that had never been transcribed before, and it derives its greatest strength from its practical orientation, which has proved beneficial to language teaching and learning. Noam Chomsky's criticisms of it are largely unjust because he has not…
Songs as Ambient Language Input in Phonology Acquisition
Au, Terry Kit-fong
Children cannot learn to speak a language simply from occasional noninteractive exposure to native speakers' input (e.g., by hearing television dialogues), but can they learn something about its phonology? To answer this question, the present study varied ambient hearing experience for 126 5- to 7-year-old native Cantonese-Chinese speakers…

Cross-linguistic transfer of phonological skills: a Malaysian perspective.
Gomez, Caroline; Reason, Rea
This study examined the phonological and reading performance in English of Malaysian children whose home language was Bahasa Malaysia (BM). A sample of 69 Malaysian Standard Two pupils (aged 7-8 years) was selected for the study. Since commencing school at the age of 6 years, the children had been learning to read in BM and had subsequently also been learning to read in English for some 12 months. The study was part of a larger scale research programme that fully recognized the limitations of tests that had not been developed and standardized in Malaysia. Nevertheless, as a first step to developing such tests, a comparison with existing norms for the Phonological Assessment Battery (PhAB) and the Wechsler Objective Reading Dimension (WORD) was undertaken in relation to information about the children's L1 and L2 language competencies. Results showed that the children's performance on PhAB was at least comparable to the UK norms while, not surprisingly, they fared less well on WORD. The results are discussed in terms of L1 and L2 transfer, whereby the transparency of written BM and the structured way in which reading is taught in BM facilitates performance on phonological tasks in English. This has implications for identifying children with phonologically based reading difficulties.

Automatic activation of word phonology from print in deep dyslexia.
Katz, R B; Lanzoni, S M
The performance of deep dyslexics in oral reading and other tasks suggests that they are poor at activating the phonology of words and non-words from printed stimuli. As the tasks ordinarily used to test deep dyslexics require controlled processing, it is possible that the phonology of printed words can be better activated on an automatic basis. This study investigated this possibility by testing a deep dyslexic patient on a lexical decision task with pairs of stimuli presented simultaneously. In Experiment 1, which used content words as stimuli, the deep dyslexic, like normal subjects, showed faster reaction times on trials with rhyming, similarly spelled stimuli (e.g. bribe-tribe) than on control trials (consisting of non-rhyming, dissimilarly spelled words), but slower reaction times on trials with non-rhyming, similarly spelled stimuli (e.g. couch-touch). When the experiment was repeated using function words as stimuli, the patient no longer showed a phonological effect. Therefore, the phonological activation of printed content words by deep dyslexics may be better than would be expected on the basis of their oral reading performance.

Learner-generated drawing for phonological and orthographic dyslexic readers.
Wang, Li-Chih; Yang, Hsien-Ming; Tasi, Hung-Ju; Chan, Shih-Yi
This study presents an examination of learner-generated drawing for different reading comprehension subtypes of dyslexic students and control students. The participants were 22 phonological dyslexic students, 20 orthographic dyslexic students, 21 double-deficit dyslexic students, and 45 age-, gender-, and IQ-matched control students. The major evaluation tools included word recognition task, orthographic task, phonological awareness task, and scenery texts and questions. Comparisons of the four groups of students showed differences among phonological dyslexia, orthographic dyslexia, double-deficit dyslexia, and the chronological age control groups in pre- and posttest performance of scenery texts. Differences also existed in relevant questions and the effect of the learner-generated drawing method. The pretest performance showed problems in the dyslexic samples in reading the scenery texts and answering relevant questions. The posttest performance revealed certain differences among phonological dyslexia, orthographic dyslexia, double-deficit dyslexia, and the chronological age control group. Finally, all dyslexic groups obtained a great effect from using the learner-generated drawing, particularly orthographic dyslexia. These results suggest that the learner-generated drawing was also useful for dyslexic students, with the potential for use in the classroom for teaching text reading to dyslexic students.

Early phonology revealed by international adoptees' birth language retention.
Choi, Jiyoun; Broersma, Mirjam; Cutler, Anne
Until at least 6 mo of age, infants show good discrimination for familiar phonetic contrasts (i.e., those heard in the environmental language) and contrasts that are unfamiliar. Adult-like discrimination (significantly worse for nonnative than for native contrasts) appears only later, by 9-10 mo. This has been interpreted as indicating that infants have no knowledge of phonology until vocabulary development begins, after 6 mo of age. Recently, however, word recognition has been observed before age 6 mo, apparently decoupling the vocabulary and phonology acquisition processes. Here we show that phonological acquisition is also in progress before 6 mo of age. The evidence comes from retention of birth-language knowledge in international adoptees. In the largest ever such study, we recruited 29 adult Dutch speakers who had been adopted from Korea when young and had no conscious knowledge of Korean language at all. Half were adopted at age 3-5 mo (before native-specific discrimination develops) and half at 17 mo or older (after word learning has begun). In a short intensive training program, we observe that adoptees (compared with 29 matched controls) more rapidly learn tripartite Korean consonant distinctions without counterparts in their later-acquired Dutch, suggesting that the adoptees retained phonological knowledge about the Korean distinction. The advantage is equivalent for the younger-adopted and the older-adopted groups, and both groups not only acquire the tripartite distinction for the trained consonants but also generalize it to untrained consonants. Although infants younger than 6 mo can still discriminate unfamiliar phonetic distinctions, this finding indicates that native-language phonological knowledge is nonetheless being acquired at that age.

Visual attention shift to printed words during spoken word recognition in Chinese: The role of phonological information.
Shen, Wei; Qu, Qingqing; Tong, Xiuhong
The aim of this study was to investigate the extent to which phonological information mediates the visual attention shift to printed Chinese words in spoken word recognition by using an eye-movement technique with a printed-word paradigm. In this paradigm, participants are visually presented with four printed words on a computer screen, which include a target word, a phonological competitor, and two distractors. Participants are then required to select the target word using a computer mouse, and the eye movements are recorded. In Experiment 1, phonological information was manipulated at the full-phonological overlap; in Experiment 2, phonological information at the partial-phonological overlap was manipulated; and in Experiment 3, the phonological competitors were manipulated to share either fulloverlap or partial-overlap with targets directly. Results of the three experiments showed that the phonological competitor effects were observed at both the full-phonological overlap and partial-phonological overlap conditions. That is, phonological competitors attracted more fixations than distractors, which suggested that phonological information mediates the visual attention shift during spoken word recognition. More importantly, we found that the mediating role of phonological information varies as a function of the phonological similarity between target words and phonological competitors.

Talieh Zarifian
Full Text Available Background and Aim: Speech and language pathologists (SLP often refer to phonological data as part of their assessment protocols in evaluating the communication skills of children. The aim of this study was to develop the Persian version of the phonological test in evaluating and diagnosing communication skills in Persian speaking children and to evaluate its validity and reliability.Methods: The Persian phonological test (PPT was conducted on 387 monolingual Persian speaking boys and girls (3-6 years of age who were selected from 12 nurseries in the northwest region of Tehran. Content validity ratio (CVR and content validity index (CVI were assessed by speechtherapists and linguists. Correlation between speech and language pathologists experts' opinions and Persian phonological test results in children with and without phonological disorders was evaluated to investigate the Persian phonological test validity. In addition, the Persian phonological test test-retest reliability was investigated.Results: Both content validity ratio and content validity index were found to be acceptable (CVR≥94.71 and CVI=97.35. The PPT validity was confirmed by finding a good correlation between s peech and language pathologists experts' opinions and Persian phonological test results ( r Kappa =0.73 and r Spearman =0.76. The percent of agreement between transcription and analyzing error patterns in test-retest (ranging from 86.27%-100% and score-rescore (ranging from 94.28%-100% showed that Persian phonological test had a very high reliability.Conclusion: The results of this study show that the Persian phonological test seems to be a suitable tool in evaluating phonological skills of Persian speaking children in clinical settings and research projects.
Speech and non-speech processing in children with phonological disorders: an electrophysiological study
Directory of Open Access Journals (Sweden)
Isabela Crivellaro Gonçalves
Full Text Available OBJECTIVE: To determine whether neurophysiological auditory brainstem responses to clicks and repeated speech stimuli differ between typically developing children and children with phonological disorders. INTRODUCTION: Phonological disorders are language impairments resulting from inadequate use of adult phonological language rules and are among the most common speech and language disorders in children (prevalence: 8 - 9%. Our hypothesis is that children with phonological disorders have basic differences in the way that their brains encode acoustic signals at brainstem level when compared to normal counterparts. METHODS: We recorded click and speech evoked auditory brainstem responses in 18 typically developing children (control group and in 18 children who were clinically diagnosed with phonological disorders (research group. The age range of the children was from 7-11 years. RESULTS: The research group exhibited significantly longer latency responses to click stimuli (waves I, III and V and speech stimuli (waves V and A when compared to the control group. DISCUSSION: These results suggest that the abnormal encoding of speech sounds may be a biological marker of phonological disorders. However, these results cannot define the biological origins of phonological problems. We also observed that speech-evoked auditory brainstem responses had a higher specificity/sensitivity for identifying phonological disorders than click-evoked auditory brainstem responses. CONCLUSIONS: Early stages of the auditory pathway processing of an acoustic stimulus are not similar in typically developing children and those with phonological disorders. These findings suggest that there are brainstem auditory pathway abnormalities in children with phonological disorders.

A recoding scheme for X-linked and pseudoautosomal loci to be used with computer programs for autosomal LOD-score analysis.
Strauch, Konstantin; Baur, Max P; Wienker, Thomas F
We present a recoding scheme that allows for a parametric multipoint X-chromosomal linkage analysis of dichotomous traits in the context of a computer program for autosomes that can use trait models with imprinting. Furthermore, with this scheme, it is possible to perform a joint multipoint analysis of X-linked and pseudoautosomal loci. It is required that (1) the marker genotypes of all female nonfounders are available and that (2) there are no male nonfounders who have daughters in the pedigree. The second requirement does not apply if the trait locus is pseudoautosomal. The X-linked marker loci are recorded by adding a dummy allele to the males' hemizygous genotypes. For modelling an X-linked trait locus, five different liability classes are defined, in conjunction with a paternal imprinting model for male nonfounders. The formulation aims at the mapping of a diallelic trait locus relative to an arbitrary number of codominant markers with known genetic distances, in cases where a program for a genuine X-chromosomal analysis is not available. 2004 S.

Neural signatures of phonological deficits in Chinese developmental dyslexia.
Cao, Fan; Yan, Xin; Wang, Zhao; Liu, Yanni; Wang, Jin; Spray, Gregory J; Deng, Yuan
There has been debate on whether phonological deficits explain reading difficulty in Chinese, since Chinese is a logographic language which does not employ grapheme-phoneme-correspondence rules and remote memorization seems to be the main method to acquire reading. In the current study, we present neuroimaging evidence that the phonological deficit is also a signature of Chinese dyslexia. Specifically, we found that Chinese children with dyslexia (DD) showed reduced brain activation in the left dorsal inferior frontal gyrus (dIFG) when compared to both age-matched controls (AC) and reading-matched controls (RC) during an auditory rhyming judgment task. This suggests that the phonological processing deficit in this region may be a signature of dyslexia in Chinese, rather than a difference due to task performance or reading ability, which was matched on DD and RC. At exactly the same region of the left dIFG, we found a positive correlation between brain activation and reading skill in DD, suggesting that the phonological deficit is associated with the severity of dyslexia. We also found increased brain activation in the right precentral gyrus in DD than both AC and RC, suggesting a compensation of reliance on articulation. Functional connectivity analyses revealed that DD had a weaker connection between the left superior temporal gyrus (STG) and fusiform gyrus (FG) than the two control groups, suggesting that the reduced connection between phonology and orthography is another neural signature of dyslexia. In contrast, DD showed greater connectivity between the left dIFG and the left inferior parietal lobule (IPL) than both control groups, suggesting a reduced segregation between the language network and default mode network in dyslexic children. We also found that connectivity between the left STG and the left dIFG was sensitive to task performance and/or reading skill rather than being dyslexic or not, because AC was greater than both RC and DD, while the

Full Text Available Phonological awareness is the ability of phonological processing of words. Children with developmental dysphasia manifest interference in the development of phonological abilities vital for the development of other language skills. The aim of this study is to investigate phonological awareness in children with typical language development and children with developmental dysphasia at preschool age. Phonological awareness is tested in 60 preschool children by a part of the ELLA test (Emerging Literacy & Language Assessment. The results showed a statistically significant difference in the tested elements of phonological awareness among children with typical language development and children with developmental dysphasia. The most significant differences are deletion of phonemes (p≤0.000, replacement of phonemes, as well as segmentation at the level of whole words (p≤0.000.
The right posterior inferior frontal gyrus contributes to phonological word decisions in the healthy brain
DEFF Research Database (Denmark)
Hartwigsen, Gesa; Price, Cathy J; Baumgaertner, Annette
There is consensus that the left hemisphere plays a dominant role in language processing, but functional imaging studies have shown that the right as well as the left posterior inferior frontal gyri (pIFG) are activated when healthy right-handed individuals make phonological word decisions. Here we...... used online transcranial magnetic stimulation (TMS) to examine the functional relevance of the right pIFG for auditory and visual phonological decisions. Healthy right-handed individuals made phonological or semantic word judgements on the same set of auditorily and visually presented words while......IFG impaired reaction times and accuracy of phonological but not semantic decisions for visually and auditorily presented words. TMS over left, right or bilateral pIFG disrupted phonological processing to a similar degree. In a follow-up experiment, the intensity threshold for delaying phonological judgements...
Top-Down Historical Phonology of Rote-Meto
Directory of Open Access Journals (Sweden)
Owen Edwards
Full Text Available This paper examines the historical phonology of the Rote-Meto languages through a top-down perspective. It describes the sound changes which have taken place between Proto-Malayo-Polynesian and the present-day languages. This reveals a number of shared innovations between Meto and the languages of west Rote, as well as changes shared by the other languages of Rote. Thus, a West Rote-Meto subgroup is identified, as well as a Nuclear Rote subgroup. Within Austronesian, there are phonological innovations shared between Rote-Meto and a number of languages of Timor and surrounding islands. This provides evidence for a Timor-Wetar-Babar subgroup, though this group does not include all languages of Timor.

Full Text Available The aim of the experiment described here was to attempt to measure adult learners' percetual interlanguage in phonology. The implementation of a methodology involving context-less lists of English words selected for their potential phonological problems is described, and the way in which learners process words they are listening to is discussed. The results of 13 Korean adults' perceptions and misperceptions are analysed: the most misperceived vowels were ID:/ and the short vowels /u, A, I, E, D, z/;c onsonants were mainly misperceived in word-final position, but 18, v, b, p, rl were misperceived to some extent in any position, and /S, j/ before the vowel /i:/; consonant clusters involving /f, 1, r/ were particularly subject to misperception. These findings have implications for the design of English pronunciation teaching materials for Koreans.

Full Text Available Purpose: To investigate parameters related to fluency, reading comprehension and phonological processing (operational and short-term memory and identify potential correlation between the variables in Dyslexia and in the absence of reading difficulties. Method: One hundred and fifteen students from the third to eighth grade of elementary school were grouped into a Control Group (CG and Group with Dyslexia (GDys. Reading of words, pseudowords and text (decoding; listening and reading comprehension; phonological short-term and working memory (repetition of pseudowords and Digit Span were evaluated. Results: The comparison of the groups showed significant differences in decoding, phonological short-term memory (repetition of pseudowords and answers to text-connecting questions (TC on reading comprehension, with the worst performances identified for GDys. In this group there were negative correlations between pseudowords repetition and TC answers and total score, both on listening comprehension. No correlations were found between operational and short-term memory (Digit Span and parameters of fluency and reading comprehension in dyslexia. For the sample without complaint, there were positive correlations between some parameters of reading fluency and repetition of pseudowords and also between answering literal questions in listening comprehension and repetition of digits on the direct and reverse order. There was no correlation with the parameters of reading comprehension. Conclusion: GDys and CG showed similar performance in listening comprehension and in understanding of explicit information and gap-filling inference on reading comprehension. Students of GDys showed worst performance in reading decoding, phonological short-term memory (pseudowords and on inferences that depends on textual cohesion understanding in reading. There were negative correlations between pseudowords repetition and TC answers and total score, both in listening comprehension.
Early lexical and phonological acquisition and its relationships.
Wiethan, Fernanda Marafiga; Nóro, Letícia Arruda; Mota, Helena Bolli
Verifying likely relationships between lexical and phonological development of children aged between 1 year to 1 year, 11 months and 29 days, who were enrolled in public kindergarten schools of Santa Maria (RS). The sample consisted of 18 children of both genders, with typical language development and aged between 1 year to 1 year, 11 months and 29 days, separated in three age subgroups. Visual recordings of spontaneous speech of each child were collected and then lexical analysis regarding the types of the said lexical items and phonological assessment were performed. The number of sounds acquired and partially acquired were counted together, and the 19 sounds and two all phones of Brazilian Portuguese were considered. To the statistical analysis, the tests of Kruskal-Wallis and Wilcoxon were used, with significance level of prelace_LT0.05. When compared the means relating to the acquired sounds and mean of the acquired and partially acquired sounds percentages, there was difference between the first and the second age subgroup, and between the first and the third subgroup. In the comparison of the said lexical items means among the age subgroups, there was difference between the first and the second subgroup, and between the first and the third subgroup again. In the comparison between the said lexical items and acquired and partially acquired sounds in each age subgroup, there was difference only in the age subgroup of 1 year and 8 months to 1 year, 11 months and 29 days, in which the sounds highlighted. The phonological and lexical domains develop as a growing process and influence each other. The Phonology has a little advantage.
Semantic and phonological coding in poor and normal readers.
Vellutino, F R; Scanlon, D M; Spearing, D
Three studies were conducted evaluating semantic and phonological coding deficits as alternative explanations of reading disability. In the first study, poor and normal readers in second and sixth grade were compared on various tests evaluating semantic development as well as on tests evaluating rapid naming and pseudoword decoding as independent measures of phonological coding ability. In a second study, the same subjects were given verbal memory and visual-verbal learning tasks using high and low meaning words as verbal stimuli and Chinese ideographs as visual stimuli. On the semantic tasks, poor readers performed below the level of the normal readers only at the sixth grade level, but, on the rapid naming and pseudoword learning tasks, they performed below the normal readers at the second as well as at the sixth grade level. On both the verbal memory and visual-verbal learning tasks, performance in poor readers approximated that of normal readers when the word stimuli were high in meaning but not when they were low in meaning. These patterns were essentially replicated in a third study that used some of the same semantic and phonological measures used in the first experiment, and verbal memory and visual-verbal learning tasks that employed word lists and visual stimuli (novel alphabetic characters) that more closely approximated those used in learning to read. It was concluded that semantic coding deficits are an unlikely cause of reading difficulties in most poor readers at the beginning stages of reading skills acquisition, but accrue as a consequence of prolonged reading difficulties in older readers. It was also concluded that phonological coding deficits are a probable cause of reading difficulties in most poor readers.
Semantic, phonologic, and verb fluency in Huntington's disease
Directory of Open Access Journals (Sweden)
Mariana Jardim Azambuja
Full Text Available Abstract Verbal fluency tasks have been identified as important indicators of executive functioning impairment in patients with frontal lobe dysfunction. Although the usual evaluation of this ability considers phonologic and semantic criteria, there is some evidence that fluency of verbs would be more sensitive in disclosing frontostriatal physiopathology since frontal regions primarily mediate retrieval of verbs. Huntington's disease usually affects these circuitries. Objective: To compare three types of verbal fluency task in the assessment of frontal-striatal dysfunction in HD subjects. Methods: We studied 26 Huntington's disease subjects, divided into two subgroups: mild (11 and moderate (15 along with 26 normal volunteers matched for age, gender and schooling, for three types of verbal fluency: phonologic fluency (F-A-S, semantic fluency and fluency of verbs. Results: Huntington's disease subjects showed a significant reduction in the number of words correctly generated in the three tasks when compared to the normal group. Both controls and Huntington's disease subjects showed a similar pattern of decreasing task performance with the greatest number of words being generated by semantic elicitation followed by verbs and lastly phonologic criteria. We did not find greater production of verbs compared with F-A-S and semantic conditions. Moreover, the fluency of verbs distinguished only the moderate group from controls. Conclusion: Our results indicated that phonologic and semantic fluency can be used to evaluate executive functioning, proving more sensitive than verb fluency. However, it is important to point out that the diverse presentations of Huntington's disease means that an extended sample is necessary for more consistent analysis of this issue.

To investigate parameters related to fluency, reading comprehension and phonological processing (operational and short-term memory) and identify potential correlation between the variables in Dyslexia and in the absence of reading difficulties. One hundred and fifteen students from the third to eighth grade of elementary school were grouped into a Control Group (CG) and Group with Dyslexia (GDys). Reading of words, pseudowords and text (decoding); listening and reading comprehension; phonological short-term and working memory (repetition of pseudowords and Digit Span) were evaluated. The comparison of the groups showed significant differences in decoding, phonological short-term memory (repetition of pseudowords) and answers to text-connecting questions (TC) on reading comprehension, with the worst performances identified for GDys. In this group there were negative correlations between pseudowords repetition and TC answers and total score, both on listening comprehension. No correlations were found between operational and short-term memory (Digit Span) and parameters of fluency and reading comprehension in dyslexia. For the sample without complaint, there were positive correlations between some parameters of reading fluency and repetition of pseudowords and also between answering literal questions in listening comprehension and repetition of digits on the direct and reverse order.

Phonological processing in Mandarin speakers with congenital amusia.
Wang, Xiao; Peng, Gang
Although there is an emerging consensus that both musical and linguistic pitch processing can be problematic for individuals with a developmental disorder termed congenital amusia, the nature of such a pitch-processing deficit, especially that demonstrated in a speech setting, remains unclear. Therefore, this study tested the performance of native Mandarin speakers, both with and without amusia, on discrimination and imitation tasks for Cantonese level tones, aiming to shed light on this issue. Results suggest that the impact of the phonological deficit, coupled with that of the domain-general pitch deficit, could provide a more comprehensive interpretation of Mandarin amusics' speech impairment. Specifically, when there was a high demand for pitch sensitivity, as in fine-grained pitch discriminations, the operation of the pitch-processing deficit played the more predominant role in modulating amusics' speech performance. But when the demand was low, as in discriminating naturally produced Cantonese level tones, the impact of the phonological deficit was more pronounced compared to that of the pitch-processing deficit. However, despite their perceptual deficits, Mandarin amusics' imitation abilities were comparable to controls'. Such selective impairment in tonal perception suggests that the phonological deficit more severely implicates amusics' input pathways.
Synchronization and phonological skills: precise auditory timing hypothesis (PATH
Directory of Open Access Journals (Sweden)
Adam eTierney
Full Text Available Phonological skills are enhanced by music training, but the mechanisms enabling this cross-domain enhancement remain unknown. To explain this cross-domain transfer, we propose a precise auditory timing hypothesis (PATH whereby entrainment practice is the core mechanism underlying enhanced phonological abilities in musicians. Both rhythmic synchronization and language skills such as consonant discrimination, detection of word and phrase boundaries, and conversational turn-taking rely on the perception of extremely fine-grained timing details in sound. Auditory-motor timing is an acoustic feature which meets all five of the pre-conditions necessary for cross-domain enhancement to occur (Patel 2011, 2012, 2014. There is overlap between the neural networks that process timing in the context of both music and language. Entrainment to music demands more precise timing sensitivity than does language processing. Moreover, auditory-motor timing integration captures the emotion of the trainee, is repeatedly practiced, and demands focused attention. The precise auditory timing hypothesis predicts that musical training emphasizing entrainment will be particularly effective in enhancing phonological skills.
The temporal courses of phonological and orthographic encoding in handwritten production in Chinese: An ERP study
Directory of Open Access Journals (Sweden)
Qingfang Zhang
Full Text Available A central issue in written production concerns how phonological codes influence the output of orthographic codes. We used a picture-word interference paradigm combined with the event-related potential technique to investigate the temporal courses of phonological and orthographic activation and their interplay in Chinese writing. Distractors were orthographically related, phonologically related, orthographically plus phonologically related, or unrelated to picture names. The behavioral results replicated the classic facilitation effect for all three types of relatedness. The ERP results indicated an orthographic effect in the time window of 370 to 500 ms (onset latency: 370 ms, a phonological effect in the time window of 460 to 500 ms (onset latency: 464 ms, and an additive pattern of both effects in both time windows, thus indicating that orthographic codes were accessed earlier than, and independent of, phonological codes in written production. The orthographic activation originates from the semantic system, whereas the phonological effect results from the activation spreading from the orthographic lexicon to the phonological lexicon. These findings substantially strengthen the existing evidence that shows that access to orthographic codes is not mediated by phonological information, and they provide important support for the orthographic autonomy hypothesis.
Children with speech sound disorder: Comparing a non-linguistic auditory approach with a phonological intervention approach to improve phonological skills
Directory of Open Access Journals (Sweden)
Cristina eMurphy
Full Text Available This study aimed to compare the effects of a non-linguistic auditory intervention approach with a phonological intervention approach on the phonological skills of children with speech sound disorder. A total of 17 children, aged 7-12 years, with speech sound disorder were randomly allocated to either the non-linguistic auditory temporal intervention group (n = 10, average age 7.7 ± 1.2 or phonological intervention group (n = 7, average age 8.6 ± 1.2. The intervention outcomes included auditory-sensory measures (auditory temporal processing skills and cognitive measures (attention, short-term memory, speech production and phonological awareness skills. The auditory approach focused on non-linguistic auditory training (eg. backward masking and frequency discrimination, whereas the phonological approach focused on speech sound training (eg. phonological organisation and awareness. Both interventions consisted of twelve 45-minute sessions delivered twice per week, for a total of nine hours. Intra-group analysis demonstrated that the auditory intervention group showed significant gains in both auditory and cognitive measures, whereas no significant gain was observed in the phonological intervention group. No significant improvement on phonological skills was observed in any of the groups. Inter-group analysis demonstrated significant differences between the improvement following training for both groups, with a more pronounced gain for the non-linguistic auditory temporal intervention in one of the visual attention measures and both auditory measures. Therefore, both analyses suggest that although the non-linguistic auditory intervention approach appeared to be the most effective intervention approach, it was not sufficient to promote the enhancement of phonological skills.

The Locus of Serial Processing in Reading Aloud: Orthography-to-Phonology Computation or Speech Planning?
Mousikou, Petroula; Rastle, Kathleen; Besner, Derek; Coltheart, Max
Dual-route theories of reading posit that a sublexical reading mechanism that operates serially and from left to right is involved in the orthography-to-phonology computation. These theories attribute the masked onset priming effect (MOPE) and the phonological Stroop effect (PSE) to the serial left-to-right operation of this mechanism. However,…

Processing of acoustic and phonological information of lexical tones in Mandarin Chinese revealed by mismatch negativity.
Yu, Keke; Wang, Ruiming; Li, Li; Li, Ping
The accurate perception of lexical tones in tonal languages involves the processing of both acoustic information and phonological information carried by the tonal signal. In this study we evaluated the relative role of the two types of information in native Chinese speaker's processing of tones at a preattentive stage with event-related potentials (ERPs), particularly the mismatch negativity (MNN). Specifically, we distinguished the acoustic from the phonological information by manipulating phonological category and acoustic interval of the stimulus materials. We found a significant main effect of phonological category for the peak latency of MMN, but a main effect of both phonological category and acoustic interval for the mean amplitude of MMN. The results indicated that the two types of information, acoustic and phonological, play different roles in the processing of Chinese lexical tones: acoustic information only impacts the extent of tonal processing, while phonological information affects both the extent and the time course of tonal processing. Implications of these findings are discussed in light of neurocognitive processes of phonological processing.

What Does a Cue Do? Comparing Phonological and Semantic Cues for Picture Naming in Aphasia
Meteyard, Lotte; Bose, Arpita
Purpose: Impaired naming is one of the most common symptoms in aphasia, often treated with cued picture naming paradigms. It has been argued that semantic cues facilitate the reliable categorization of the picture, and phonological cues facilitate the retrieval of target phonology. To test these hypotheses, we compared the effectiveness of…

Correlations between vocabulary and phonological acquisition: number of words produced versus acquired consonants.
Wiethan, Fernanda Marafiga; Mota, Helena Bolli; Moraes, Anaelena Bragança de
To verify the probable correlations between the number of word types and the number of consonants in the general phonological system in children with typical language development. Study participants were 186 children aged one year and six months to five years, 11 months and 29 days who were monolingual Brazilian Portuguese speakers with typical language development. Data collection involved speech, language and hearing assessments and spontaneous speech recordings. Phonology was assessed with regard to the number of acquired consonants in the general phonological system, in each syllable structure and in Implicational Model of Feature Complexity (IMFC) levels. Vocabulary was assessed with regard to number of word types produced. These data were compared across age groups. After that, correlations between the word types produced and the variables established for the phonological system were analyzed. The significance level adopted was 5%. All phonological aspects evaluated presented gradual growth. Word types produced showed a similar behavior, though with a small regression at the age of five years. Different positive correlations occurred between the spoken word types and the variables analyzed in the phonological system. Only one negative correlation occurred with respect to the production of complex onset in the last age group analyzed. The phonology and vocabulary of the study participants present similar behaviors. There are many positive correlations between the word types produced and the different aspects of phonology, except regarding complex onset.
Study the left prefrontal cortex activity of Chinese children with dyslexia in phonological processing by NIRS
Zhang, Zhili; Li, Ting; Zheng, Yi; Luo, Qingming; Song, Ranran; Gong, Hui
Developmental dyslexia, a kind of prevalent psychological disease, represents that dyslexic children have unexpected difficulties in phonological processing and recognition test of Chinese characters. Some functional imaging technologies, such as fMRI and PET, have been used to study the brain activities of the children with dyslexia whose first language is English. In this paper, a portable, 16-channel, continuous-wave (CW) NIRS instrument was used to monitor the concentration changes of each hemoglobin species when Chinese children did the task of phonological processing and recognition test. The NIRS recorded the hemodynamic changes in the left prefrontal cortex of the children. 20 dyslexia-reading children (10~12 years old) and 20 normal-reading children took part in the phonological processing of Chinese characters including the phonological awareness section and the phonological decoding section. During the phonological awareness section, the changed concentration of deoxy-hemoglobin in dyslexia-reading children were significantly higher (p<0.05) than normal-reading children in the left ventrolateral prefrontal cortex (VLPFC). While in the phonological decoding section, both normal and dyslexic reading children had more activity in the left VLPFC, but only normal-reading children had activity in the left middorsal prefrontal cortex. In conclusion, both dyslexic and normal-reading children have activity in the left prefrontal cortex, but the degree and the areas of the prefrontal cortex activity are different between them when they did phonological processing.

Implicit Phonological and Semantic Processing in Children with Developmental Dyslexia: Evidence from Event-Related Potentials
Jednorog, K.; Marchewka, A.; Tacikowski, P.; Grabowska, A.
Dyslexia is characterized by a core phonological deficit, although recent studies indicate that semantic impairment also contributes to this condition. In this study, event-related potentials (ERP) were used to examine whether the N400 wave in dyslexic children is modulated by phonological or semantic priming, similarly to age-matched controls.…
Neural Correlates of Phonological Processing in Speech Sound Disorder: A Functional Magnetic Resonance Imaging Study
Tkach, Jean A.; Chen, Xu; Freebairn, Lisa A.; Schmithorst, Vincent J.; Holland, Scott K.; Lewis, Barbara A.
Speech sound disorders (SSD) are the largest group of communication disorders observed in children. One explanation for these disorders is that children with SSD fail to form stable phonological representations when acquiring the speech sound system of their language due to poor phonological memory (PM). The goal of this study was to examine PM in…

Developmental surface and phonological dyslexia in both Greek and English.
Sotiropoulos, Andreas; Hanley, J Richard
The hallmark of developmental surface dyslexia in English and French is inaccurate reading of words with atypical spelling-sound correspondences. According to Douklias, Masterson and Hanley (2009), surface dyslexia can also be observed in Greek (a transparent orthography for reading that does not contain words of this kind). Their findings suggested that surface dyslexia in Greek can be characterized by slow reading of familiar words, and by inaccurate spelling of words with atypical sound-spelling correspondences (Greek is less transparent for spelling than for reading). In this study, we report seven adult cases whose slow reading and impaired spelling accuracy satisfied these criteria for Greek surface dyslexia. When asked to read words with atypical grapheme-phoneme correspondences in English (their second language), their accuracy was severely impaired. A co-occurrence was also observed between impaired spelling of words with atypical phoneme-grapheme correspondences in English and Greek. These co-occurrences provide strong evidence that surface dyslexia genuinely exists in Greek and that slow reading of real words in Greek reflects the same underlying impairment as that which produces inaccurate reading of atypical words in English. Two further individuals were observed with impaired reading and spelling of nonwords in both languages, consistent with developmental phonological dyslexia. Neither of the phonological dyslexics read words slowly. In terms of computational models of reading aloud, these findings suggest that slow reading by dyslexics in transparent orthographies is the consequence of a developmental impairment of the lexical (Coltheart, Rastle, Perry, Langdon, & Zeigler, 2001; Perry, Ziegler, & Zorzi, 2010) or semantic reading route (Plaut, McClelland, Seidenberg, & Patterson, 1996). This outcome provides evidence that the neurophysiological substrate(s) that support the lexical/semantic and the phonological pathways that are involved in reading
Phonological recovery in Spanish developmental dyslexics through the tip-of-the-tongue paradigm.
Suárez-Coalla, Paz; Collazo Alonso, Aida; González-Nosti, María
Developmental dyslexics have difficulties accessing and retrieving the phonological form of words, in the absence of a deficit at the semantic level. The aim of this work was to study, through the Tip-of-the-tongue (TOT) paradigm, the problems of lexical access in Spanish-speaking developmental dyslexics and the relationship with their phonological awareness. A group of developmental dyslexics (14) and other children without reading difficulties (14), aged 7 to 12, performed a picture naming task of medium and low frequency and a task of phonological awareness. The results indicated that dyslexic children generally show a greater number of TOT phenomena than the control group. Despite being able to provide semantic information of the drawing, they had difficulties retrieving partial phonological information. These results indicate that developmental dyslexic children have particular difficulty in accessing the phonological form of words, which may be interesting for the development of intervention programs for these children.

Selective attention to phonology dynamically modulates initial encoding of auditory words within the left hemisphere.
Yoncheva, Yuliya; Maurer, Urs; Zevin, Jason D; McCandliss, Bruce D
Selective attention to phonology, i.e., the ability to attend to sub-syllabic units within spoken words, is a critical precursor to literacy acquisition. Recent functional magnetic resonance imaging evidence has demonstrated that a left-lateralized network of frontal, temporal, and posterior language regions, including the visual word form area, supports this skill. The current event-related potential (ERP) study investigated the temporal dynamics of selective attention to phonology during spoken word perception. We tested the hypothesis that selective attention to phonology dynamically modulates stimulus encoding by recruiting left-lateralized processes specifically while the information critical for performance is unfolding. Selective attention to phonology was captured by manipulating listening goals: skilled adult readers attended to either rhyme or melody within auditory stimulus pairs. Each pair superimposed rhyming and melodic information ensuring identical sensory stimulation. Selective attention to phonology produced distinct early and late topographic ERP effects during stimulus encoding. Data-driven source localization analyses revealed that selective attention to phonology led to significantly greater recruitment of left-lateralized posterior and extensive temporal regions, which was notably concurrent with the rhyme-relevant information within the word. Furthermore, selective attention effects were specific to auditory stimulus encoding and not observed in response to cues, arguing against the notion that they reflect sustained task setting. Collectively, these results demonstrate that selective attention to phonology dynamically engages a left-lateralized network during the critical time-period of perception for achieving phonological analysis goals. These findings suggest a key role for selective attention in on-line phonological computations. Furthermore, these findings motivate future research on the role that neural mechanisms of attention may

Phonologically-based biomarkers for major depressive disorder
Trevino, Andrea Carolina; Quatieri, Thomas Francis; Malyska, Nicolas
Of increasing importance in the civilian and military population is the recognition of major depressive disorder at its earliest stages and intervention before the onset of severe symptoms. Toward the goal of more effective monitoring of depression severity, we introduce vocal biomarkers that are derived automatically from phonologically-based measures of speech rate. To assess our measures, we use a 35-speaker free-response speech database of subjects treated for depression over a 6-week duration. We find that dissecting average measures of speech rate into phone-specific characteristics and, in particular, combined phone-duration measures uncovers stronger relationships between speech rate and depression severity than global measures previously reported for a speech-rate biomarker. Results of this study are supported by correlation of our measures with depression severity and classification of depression state with these vocal measures. Our approach provides a general framework for analyzing individual symptom categories through phonological units, and supports the premise that speaking rate can be an indicator of psychomotor retardation severity.
On the role of perception in shaping phonological assimilation rules.
Hura, S L; Lindblom, B; Diehl, R L
Assimilation of nasals to the place of articulation of following consonants is a common and natural process among the world's languages. Recent phonological theory attributes this naturalness to the postulated geometry of articulatory features and the notion of spreading (McCarthy, 1988). Others view assimilation as a result of perception (Ohala, 1990), or as perceptually tolerated articulatory simplification (Kohler, 1990). Kohler notes that certain consonant classes (such as nasals and stops) are more likely than other classes (such as fricatives) to undergo place assimilation to a following consonant. To explain this pattern, he proposes that assimilation tends not to occur when the members of a consonant class are relatively distinctive perceptually, such that their articulatory reduction would be particularly salient. This explanation, of course, presupposes that the stops and nasals which undergo place assimilation are less distinctive than fricatives, which tend not to assimilate. We report experimental results that confirm Kohler's perceptual assumption: In the context of a following word initial stop, fricatives were less confusable than nasals or unreleased stops. We conclude, in agreement with Ohala and Kohler, that perceptual factors are likely to shape phonological assimilation rules.
Effects of a phonological awareness program on English reading and spelling among Hong Kong Chinese ESL children.
Yeung, Susanna S S; Siegel, Linda S; Chan, Carol K K
This study investigated the effects of a 12-week language-enriched phonological awareness instruction on 76 Hong Kong young children who were learning English as a second language. The children were assigned randomly to receive the instruction on phonological awareness skills embedded in vocabulary learning activities or comparison instruction which consisted of vocabulary learning and writing tasks but no direct instruction in phonological awareness skills. They were tested on receptive and expressive vocabulary, phonological awareness at the syllable, rhyme and phoneme levels, reading, and spelling in English before and after the program implementation. The results indicated that children who received the phonological awareness instruction performed significantly better than the comparison group on English word reading, spelling, phonological awareness at all levels and expressive vocabulary on the posttest when age, general intelligence and the pretest scores were controlled statistically. The findings suggest that phonological awareness instruction embedded in vocabulary learning activities might be beneficial to kindergarteners learning English as a second language.
Phonological, visual, and semantic coding strategies and children's short-term picture memory span.
Henry, Lucy A; Messer, David; Luger-Klein, Scarlett; Crane, Laura
Three experiments addressed controversies in the previous literature on the development of phonological and other forms of short-term memory coding in children, using assessments of picture memory span that ruled out potentially confounding effects of verbal input and output. Picture materials were varied in terms of phonological similarity, visual similarity, semantic similarity, and word length. Older children (6/8-year-olds), but not younger children (4/5-year-olds), demonstrated robust and consistent phonological similarity and word length effects, indicating that they were using phonological coding strategies. This confirmed findings initially reported by Conrad (1971), but subsequently questioned by other authors. However, in contrast to some previous research, little evidence was found for a distinct visual coding stage at 4 years, casting doubt on assumptions that this is a developmental stage that consistently precedes phonological coding. There was some evidence for a dual visual and phonological coding stage prior to exclusive use of phonological coding at around 5-6 years. Evidence for semantic similarity effects was limited, suggesting that semantic coding is not a key method by which young children recall lists of pictures.
Phonological working memory and its relationship with language abilities in children with cochlear implants

Fatemeh Haresabadi
Full Text Available Background and Aim: Many studies have demonstrated a close relationship between phonological working memory and language abilities in normal children and children with language developmental disorders, such as those with cochlear implants. A review of these studies would clarify communication and learning in such children and provide more comprehensive information regarding their education and treatment. In this study, the characteristics of phonological working memory and its relationship with language abilities in children with cochlear implants was examined.Recent Findings: In this study, the authors studied the characteristics of phonological working memory and its relationship with language abilities of children with cochlear implants. These studies showed that in addition to demographic variables, phonological working memory is a factor that affects language development in children with cochlear implants. Children with cochlear implants typically have a shorter memory span.Conclusion: It is thought that the deficiency in primary auditory sensory input and language stimulation caused by difficulties in the processing and rehearsal of auditory information in phonological working memory is the main cause of the short memory span in such children. Conversely, phonological working memory problems may have adverse effects on the language abilities in such children. Therefore, to provide comprehensive and appropriate treatment for children with cochlear implants, the reciprocal relationship between language abilities and phonological working memory should be considered.
The effect of Phonological Encoding Complexity on Speech Fluency of Stuttering and Non-Stuttering Children

Sara Ramezani
Full Text Available Objective: Stuttering is a fairly common speech disorder. However, the etiology is poorly understood and is likely to be heterogeneous. The aim of this research is to investigate phonological encoding complexity on speech fluency in 6-9 year old stuttering children in comparison with non-stutterers in Tehran. Materials & Methods: This cross-sectional, descriptive analytic research was done on 18 stuttering children with profound and severe level and 18 non-stuttering children. The stuttering subjects were selected by convenience and normal subjects were matched to stuttering subjects by gender, age and geographics. A non-word test comprising 87 non-words was used to investigate phonological encoding and phonological complexity effects on speech fluency. Stimuli were presented in random order with approximately 5 seconds between items, using a computer via external Toshiba SOMIC SM-818 headphone and requested subject was asked to repeat them. Results: The results indicated that speech fluency decreased significantly (P<0.05 by increasing phonological complexity comparing to controls. Conclusion: The findings of the present research seem to suggest that, stuttering children may have deficits in phonological encoding. The deficit has been increased with phonological encoding complexity. Based on covert repair hypothesis, phonological difficulty may cause covert self- repair and leads to different patterns of stuttering.
The phonological and visual basis of developmental dyslexia in Brazilian Portuguese reading children.
Directory of Open Access Journals (Sweden)
Giseli Donadon Germano
Full Text Available Evidence from opaque languages suggests that visual attention processing abilities in addition to phonological skills may act as cognitive underpinnings of developmental dyslexia. We explored the role of these two cognitive abilities on reading fluency in Brazilian Portuguese, a more transparent orthography than French or English. Sixty-six dyslexic and normal Brazilian Portuguese children participated. They were administered three tasks of phonological skills (phoneme identification, phoneme and syllable blending and three visual tasks (a letter global report task and two non-verbal tasks of visual closure and visual constancy. Results show that Brazilian Portuguese dyslexic children are impaired not only in phonological processing but further in visual processing. The phonological and visual processing abilities significantly and independently contribute to reading fluency in the whole population. Last, different cognitively homogeneous subtypes can be identified in the Brazilian Portuguese dyslexic population. Two subsets of dyslexic children were identified as having a single cognitive disorder, phonological or visual; another group exhibited a double deficit and a few children showed no visual or phonological disorder. Thus the current findings extend previous data from more opaque orthographies as French and English, in showing the importance of investigating visual processing skills in addition to phonological skills in dyslexic children whatever their language orthography transparency.
Topographical gradients of semantics and phonology revealed by temporal lobe stimulation.
Miozzo, Michele; Williams, Alicia C; McKhann, Guy M; Hamberger, Marla J
Word retrieval is a fundamental component of oral communication, and it is well established that this function is supported by left temporal cortex. Nevertheless, the specific temporal areas mediating word retrieval and the particular linguistic processes these regions support have not been well delineated. Toward this end, we analyzed over 1000 naming errors induced by left temporal cortical stimulation in epilepsy surgery patients. Errors were primarily semantic (lemon → "pear"), phonological (horn → "corn"), non-responses, and delayed responses (correct responses after a delay), and each error type appeared predominantly in a specific region: semantic errors in mid-middle temporal gyrus (TG), phonological errors and delayed responses in middle and posterior superior TG, and non-responses in anterior inferior TG. To the extent that semantic errors, phonological errors and delayed responses reflect disruptions in different processes, our results imply topographical specialization of semantic and phonological processing. Specifically, results revealed an inferior-to-superior gradient, with more superior regions associated with phonological processing. Further, errors were increasingly semantically related to targets toward posterior temporal cortex. We speculate that detailed semantic input is needed to support phonological retrieval, and thus, the specificity of semantic input increases progressively toward posterior temporal regions implicated in phonological processing.

Phonological deficits in specific language impairment and developmental dyslexia: towards a multidimensional model
Ramus, Franck; Marshall, Chloe R.; Rosen, Stuart
An on-going debate surrounds the relationship between specific language impairment and developmental dyslexia, in particular with respect to their phonological abilities. Are these distinct disorders? To what extent do they overlap? Which cognitive and linguistic profiles correspond to specific language impairment, dyslexia and comorbid cases? At least three different models have been proposed: the severity model, the additional deficit model and the component model. We address this issue by comparing children with specific language impairment only, those with dyslexia-only, those with specific language impairment and dyslexia and those with no impairment, using a broad test battery of language skills. We find that specific language impairment and dyslexia do not always co-occur, and that some children with specific language impairment do not have a phonological deficit. Using factor analysis, we find that language abilities across the four groups of children have at least three independent sources of variance: one for non-phonological language skills and two for distinct sets of phonological abilities (which we term phonological skills versus phonological representations). Furthermore, children with specific language impairment and dyslexia show partly distinct profiles of phonological deficit along these two dimensions. We conclude that a multiple-component model of language abilities best explains the relationship between specific language impairment and dyslexia and the different profiles of impairment that are observed.

Inter-subject variability modulates phonological advance planning in the production of adjective-noun phrases.
Michel Lange, Violaine; Laganaro, Marina
The literature on advance phonological planning in adjective-noun phrases (NPs) presents diverging results: while many experimental studies suggest that the entire NP is encoded before articulation, other results favor a span of encoding limited to the first word. Although cross-linguistic differences in the structure of adjective-NPs may account for some of these contrasting results, divergences have been reported even among similar languages and syntactic structures. Here we examined whether inter-individual differences account for variability in the span of phonological planning in the production of French NPs, where previous results indicated encoding limited to the first word. The span of phonological encoding is tested with the picture-word interference (PWI) paradigm using phonological distractors related to the noun or to the adjective of the NPs. In Experiment 1, phonological priming effects were limited to the first word in adjective NPs whichever the position of the adjective (pre-nominal or post-nominal). Crucially, phonological priming effects on the second word interacted with speakers' production speed suggesting different encoding strategies for participants. In Experiment 2, we tested this hypothesis further with a larger group of participants. Results clearly showed that slow and fast initializing participants presented different phonological priming patterns on the last element of adjective-NPs: while the first word was primed by a distractor for all speakers, only the slow speaker group presented a priming effect on the second element of the NP. These results show that the span of phonological encoding is modulated by inter-individual strategies: in experimental paradigms some speakers plan word by word whereas others encode beyond the initial word. We suggest that the diverging results reported in the literature on advance phonological planning may partly be reconciled in light of the present results.
Phonological errors predominate in Arabic spelling across grades 1-9.
Abu-Rabia, Salim; Taha, Haitham
Most of the spelling error analysis has been conducted in Latin orthographies and rarely conducted in other orthographies like Arabic. Two hundred and eighty-eight students in grades 1-9 participated in the study. They were presented nine lists of words to test their spelling skills. Their spelling errors were analyzed by error categories. The most frequent errors were phonological. The results did not indicate any significant differences in the percentages of phonological errors across grades one to nine.Thus, phonology probably presents the greatest challenge to students developing spelling skills in Arabic.
Neural correlates of sublexical processing in phonological working memory.
McGettigan, Carolyn; Warren, Jane E; Eisner, Frank; Marshall, Chloe R; Shanmugalingam, Pradheep; Scott, Sophie K
This study investigated links between working memory and speech processing systems. We used delayed pseudoword repetition in fMRI to investigate the neural correlates of sublexical structure in phonological working memory (pWM). We orthogonally varied the number of syllables and consonant clusters in auditory pseudowords and measured the neural responses to these manipulations under conditions of covert rehearsal (Experiment 1). A left-dominant network of temporal and motor cortex showed increased activity for longer items, with motor cortex only showing greater activity concomitant with adding consonant clusters. An individual-differences analysis revealed a significant positive relationship between activity in the angular gyrus and the hippocampus, and accuracy on pseudoword repetition. As models of pWM stipulate that its neural correlates should be activated during both perception and production/rehearsal [Buchsbaum, B. R., & D'Esposito, M.

Bower (Ed.), The psychology of learning and motivation: Advances in research and theory (Vol. 8, pp. 47-89). New York: Academic Press, 1974], we further assessed the effects of the two factors in a separate passive listening experiment (Experiment 2). In this experiment, the effect of the number of syllables was concentrated in posterior-medial regions of the supratemporal plane bilaterally, although there was no evidence of a significant response to added clusters. Taken together, the results identify the planum temporale as a key region in pWM; within this region, representations are likely to take the form of auditory or audiomotor "templates" or "chunks" at the level of the syllable

Deconstructing continuous flash suppression
Yang, Eunice; Blake, Randolph
In this paper, we asked to what extent the depth of interocular suppression engendered by continuous flash suppression (CFS) varies depending on spatiotemporal properties of the suppressed stimulus and CFS suppressor. An answer to this question could have implications for interpreting the results in which CFS influences the processing of different categories of stimuli to different extents. In a series of experiments, we measured the selectivity and depth of suppression (i.e., elevation in co...
Some Problems of American Students in Mastering Persian Phonology.
Ghadessy, Esmael
An adult learning to speak a foreign language normally retains an "accent" which may affect the intelligibility of certain sounds, but more often simply conveys the fact that the speaker is a non-native speaker. Various scholars have experimented and discussed the elements involved in a foreign accent. However, in Iran very few researchers have attempted to verify scientifically what are the phonetic and phonological aspects of an "accent." This author tried to determine whether or not a selected group of words, emphasizing stop voicing, produced by native speakers of Persian had significant phonetic and phonemic differences from those achieved by the American students. Subjects for the experiments were three groups of students, one Iranian, two American. A contrastive analysis of the Persian and the English stop consonants was made. An identical measurement test for all three groups was administered. Utilized was a Kay Sona-graph for acoustic analysis, and all spoken data from the Iranian group were compared with those of the American groups. An examination of acoustic correlates of Tehran stops produced by American students shows that the phonetically different but similar feature of /voice/ found in Tehran, Persian and English stops is intuitive to the Americans, and that the language learner cannot readily disassociate a phonological feature from habits of articulation. The results of this research support using the phonetic method for adult learners who want to improve their pronunciation ability. Further research and experimentation is necessary on the effect of the suprasegmental elements on a foreign accent and the most effective teaching materials and methods and to explore other possible techniques in the teaching process.
The ontogeny of phonological categories and the primacy of lexical learning in linguistic development.

In this paper, we draw on recent developments in several areas of cognitive science that suggest that the lexicon is at the core of grammatical generalizations at several different levels of representation. Evidence comes from many sources, including recent studies on language processing in adults and on language acquisition in children. Phonological behavior is influenced very early by pattern frequency in the lexicon of the ambient language, and we propose that phonological acquisition might provide the initial bootstrapping into grammatical generalization in general. The phonological categories over which pattern frequencies are calculated, however, are neither transparently available in the audiovisual signal nor deterministically fixed by the physiological and perceptual capacities of the species. Therefore, we need several age-appropriate models of how the lexicon can influence a child's interactions with the ambient language over the course of phonological acquisition.
Symbolic Numerical Magnitude Processing Is as Important to Arithmetic as Phonological Awareness Is to Reading.

Full Text Available In this article, we tested, using a 1-year longitudinal design, whether symbolic numerical magnitude processing or children's numerical representation of Arabic digits, is as important to arithmetic as phonological awareness is to reading. Children completed measures of symbolic comparison, phonological awareness, arithmetic, reading at the start of third grade and the latter two were retested at the start of fourth grade. Cross-sectional and longitudinal correlations indicated that symbolic comparison was a powerful domain-specific predictor of arithmetic and that phonological awareness was a unique predictor of reading. Crucially, the strength of these independent associations was not significantly different. This indicates that symbolic numerical magnitude processing is as important to arithmetic development as phonological awareness is to reading and suggests that symbolic numerical magnitude processing is a good candidate for screening children at risk for developing mathematical difficulties.
Phonological experience modulates voice discrimination: Evidence from functional brain networks analysis.
Hu, Xueping; Wang, Xiangpeng; Gu, Yan; Luo, Pei; Yin, Shouhang; Wang, Lijun; Fu, Chao; Qiao, Lei; Du, Yi; Chen, Antao
Numerous behavioral studies have found a modulation effect of phonological experience on voice discrimination. However, the neural substrates underpinning this phenomenon are poorly understood. Here we manipulated language familiarity to test the hypothesis that phonological experience affects voice discrimination via mediating the engagement of multiple perceptual and cognitive resources. The results showed that during voice discrimination, the activation of several prefrontal regions was modulated by language familiarity. More importantly, the same effect was observed concerning the functional connectivity from the fronto-parietal network to the voice-identity network (VIN), and from the default mode network to the VIN. Our findings indicate that phonological experience could bias the recruitment of cognitive control and information retrieval/comparison processes during voice discrimination. Therefore, the study unravels the neural substrates subserving the modulation effect of phonological experience on voice discrimination, and provides new insights into studying voice discrimination from the perspective of network interactions.

Phonological awareness: explicit instruction for young deaf and hard-of-hearing children.
Miller, Elizabeth M; Lederberg, Amy R; Easterbrooks, Susan R
The goal of this study was to explore the development of spoken phonological awareness for deaf and hard-of-hearing children (DHH) with functional hearing (i.e., the ability to access spoken language through hearing). Teachers explicitly taught five preschoolers the phonological awareness skills of syllable segmentation, initial phoneme isolation, and rhyme discrimination in the context of a multifaceted emergent literacy intervention. Instruction occurred in settings where teachers used simultaneous communication or spoken language only. A multiple-baseline across skills design documented a functional relation between instruction and skill acquisition for those children who did not have the skills at baseline with one exception; one child did not meet criteria for syllable segmentation. These results were confirmed by changes on phonological awareness tests that were administered at the beginning and end of the school year. We found that DHH children who varied in primary communication mode, chronological age, and language ability all benefited from explicit instruction in phonological awareness.
The Selective Impairment of the Phonological Output Buffer: Evidence From a Chinese Patient
Directory of Open Access Journals (Sweden)
Hua Shu
Full Text Available We present a Chinese-speaking patient, SJ, who makes phonological errors across all tasks involving oral production. Detailed analyses of the errors across different tasks reveal that the patterns are very similar for reading, oral picture naming, and repetition tasks, which are also comparable to the error patterns of the phonological buffer deficit cases reported in the literature. The nature of the errors invites us to conclude that the patient's phonological output buffer is selectively impaired. Different from previously reported cases, SJ's deficits in oral production tasks are not accompanied by a similar impairment of writing performance. We argue that this dissociation is evidence that the phonological output buffer is not involved in writing Chinese words. Furthermore, the majority of SJ's errors occur at the onset of a syllable, indicating that the buffer has a structure that makes the onset more prone to impairment.

Phonological complexity in school-aged children who stutter and exhibit a language disorder.
Wolk, Lesley; LaSalle, Lisa R
The Index of Phonological Complexity and the Word Complexity Measure are two measures of the phonological complexity of a word. Other phonological measures such as phonological neighborhood density have been used to compare stuttered versus fluent words. It appears that in preschoolers who stutter, the length and complexity of the utterance is more influential than the phonetic features of the stuttered word. The present hypothesis was that in school-age children who stutter, stuttered words would be more phonologically complex than fluent words, when the length and complexity of the utterance containing them is comparable. School-age speakers who stutter were hypothesized to differ from those with a concomitant language disorder. Sixteen speakers, six females and ten males (M age=12;3; Range=7;7 to 19;5) available from an online database, were divided into eight who had a concomitant language disorder (S+LD) and eight age- and sex-matched speakers who did not (S-Only). When all stuttered content words were identified, S+LD speakers produced more repetitions, and S-Only speakers produced more inaudible sound prolongations. When stuttered content words were matched to fluent content words and when talker groups were combined, stuttered words were significantly (p≤0.01) higher in both the Index of Phonological Complexity and the Word Complexity Measure and lower in density ("sparser") than fluent words. Results corroborate those of previous researchers. Future research directions are suggested, such as cross-sectional designs to evaluate developmental patterns of phonological complexity and stuttering plus language disordered connections. The reader will be able to: (a) Define and describe phonological complexity; (b) Define phonological neighborhood density and summarize the literature on the topic; (c) Describe the Index of Phonological Complexity (IPC) for a given word; (d) Describe the Word Complexity Measure (WCM) for a given word; (e) Summarize two findings

Phonetic radicals, not phonological coding systems, support orthographic learning via self-teaching in Chinese.
Li, Luan; Wang, Hua-Chen; Castles, Anne; Hsieh, Miao-Ling; Marinus, Eva
According to the self-teaching hypothesis (Share, 1995), phonological decoding is fundamental to acquiring orthographic representations of novel written words. However, phonological decoding is not straightforward in non-alphabetic scripts such as Chinese, where words are presented as characters. Here, we present the first study investigating the role of phonological decoding in orthographic learning in Chinese. We examined two possible types of phonological decoding: the use of phonetic radicals, an internal phonological aid, andthe use of Zhuyin, an external phonological coding system. Seventy-three Grade 2 children were taught the pronunciations and meanings of twelve novel compound characters over four days. They were then exposed to the written characters in short stories, and were assessed on their reading accuracy and on their subsequent orthographic learning via orthographic choice and spelling tasks. The novel characters were assigned three different types of pronunciation in relation to its phonetic radical - (1) a pronunciation that is identical to the phonetic radical in isolation; (2) a common alternative pronunciation associated with the phonetic radical when it appears in other characters; and (3) a pronunciation that is unrelated to the phonetic radical. The presence of Zhuyin was also manipulated. The children read the novel characters more accurately when phonological cues from the phonetic radicals were available and in the presence of Zhuyin. However, only the phonetic radicals facilitated orthographic learning. The findings provide the first empirical evidence of orthographic learning via self-teaching in Chinese, and reveal how phonological decoding functions to support learning in non-alphabetic writing systems.

Phonological, visual, and semantic coding strategies and children's short-term picture memory span
Henry, L.; Messer, D. J.; Luger-Klein, S.; Crane, L.
Three experiments addressed controversies in the previous literature on the development of phonological and other forms of short-term memory coding in children, using assessments of picture memory span that ruled out potentially confounding effects of verbal input and output. Picture materials were varied in terms of phonological similarity, visual similarity, semantic similarity, and word length. Older children (6/8-year-olds), but not younger children (4/5-year-olds), demonstrated robust an...
The role of consciousness in the phonological loop: hidden in plain sight
Buchsbaum, Bradley R.
We know from everyday experience that when we need to keep a small amount of verbal information "in mind" for a short period, an effective cognitive strategy is to silently rehearse the words. This basic cognitive strategy has been elegantly codified in Baddeley and colleagues model of verbal working memory, the phonological loop. Here we explore how the intuitive appeal of the phonological loop is grounded in the phenomenological experience of subvocal rehearsal as consisting of an interacti...
The relationship of phonological ability, speech perception and auditory perception in adults with dyslexia.
Directory of Open Access Journals (Sweden)
Jeremy eLaw
Full Text Available This study investigated whether auditory, speech perception and phonological skills are tightly interrelated or independently contributing to reading. We assessed each of these three skills in 36 adults with a past diagnosis of dyslexia and 54 matched normal reading adults. Phonological skills were tested by the typical threefold tasks, i.e. rapid automatic naming, verbal short term memory and phonological awareness. Dynamic auditory processing skills were assessed by means of a frequency modulation (FM and an amplitude rise time (RT; an intensity discrimination task (ID was included as a non-dynamic control task. Speech perception was assessed by means of sentences and words in noise tasks. Group analysis revealed significant group differences in auditory tasks (i.e. RT and ID and in phonological processing measures, yet no differences were found for speech perception. In addition, performance on RT discrimination correlated with reading but this relation was mediated by phonological processing and not by speech in noise. Finally, inspection of the individual scores revealed that the dyslexic readers showed an increased proportion of deviant subjects on the slow-dynamic auditory and phonological tasks, yet each individual dyslexic reader does not display a clear pattern of deficiencies across the levels of processing skills. Although our results support phonological and slow-rate dynamic auditory deficits which relate to literacy, they suggest that at the individual level, problems in reading and writing cannot be explained by the cascading auditory theory. Instead, dyslexic adults seem to vary considerably in the extent to which each of the auditory and phonological factors are expressed and interact with environmental and higher-order cognitive influences.

Full Text Available This paper presents preliminary study of R&D on Teaching Materials Model of English Phonology for EF2L. The preliminary study aims at finding out the phonological fossilization of adult learners of English in Javanese context and figuring out the factors influencing them. 25 fourth-semester Javanese students of English Departement from 5 universities in Semarang municipality were selected as respondents. The data were collected from observation, interview and documentation. The results show that phonological fossilizations occur on vowel (/e/ instead of /i/ in ‗english' /ˈɪŋ.glɪʃ/, /a/ instead of /æ/ in ‗aspect' /ˈæs.pekt/, it also occurs in /Ʌ,e, ǝ/ mostly in initial sound , consonant (/nð/ instead of /ð/ in ‗the' /ðǝ/, /ŋ/ instead of /ʤ/ in ‗change' /tʃeɪndʒ/, also in /tʃ, ϴ,ð,ʃ,v,Ʒ,z,j,k,g, suffix –ed and –es, and silent letter, and diphthong (/o/ instead of /ǝu/ in ‗over' /ǝuvǝr/ and in ‗power' /paʊər /, also in/ei,au/ . Factors affecting the occurrence of phonological fossilization are 1 the interference of respondents' mother tongue, such as Javanese tends to add sound /n/ in /nðǝlɔk/ ‗ndelok' and it interferes in pronouncing ‗the' to /nðǝ/ instead of /ðǝ/; 2 the learning materials of English Phonology course does not yet accommodate the learner's errors and or learner's fossilizations. These findings can be used as recommendation to develop teaching materials of English Phonology for EF2L.

Full Text Available Background and Aim: Reading is one of the human's communicative skills. Phonological awareness and rapid automatized naming are parts of the person's linguistic knowledge. Research in different languages and communities suggest that there is a relation between phonological awareness, rapid automatized naming and reading. To survey these relations in Persian language is the aim of this study.Methods: In this study 130 male students from the first grade were selected at random. They were normal in IQ, visual and hearing status. Language development was also normal in these children. This study was a cross-sectional one. Pearson correlation coefficient and linear regression test were used to analyze data.Results: The relation between phonological awareness and automatized rapid naming was significant (p<0.0001. Pearson correlation coefficient between phonological awareness and reading was direct (0.86. Pearson correlation coefficient between rapid automatized naming and reading was indirect that equals -0.87. In investigating the relation of two variables simultaneously with reading we concluded that the relation between phonological awareness, rapid automatized naming and reading is statistically significant (p<0.0001.Conclusion: The results of this research revealed that in Persian language like other languages there is a relation between phonological awareness, rapid automatized naming, and reading. Reading skills of children could be improved with this exercises.
The Relationship Between Speech, Language, and Phonological Awareness in Preschool-Age Children With Developmental Disabilities.
Barton-Hulsey, Andrea; Sevcik, Rose A; Romski, MaryAnn
A number of intrinsic factors, including expressive speech skills, have been suggested to place children with developmental disabilities at risk for limited development of reading skills. This study examines the relationship between these factors, speech ability, and children's phonological awareness skills. A nonexperimental study design was used to examine the relationship between intrinsic skills of speech, language, print, and letter-sound knowledge to phonological awareness in 42 children with developmental disabilities between the ages of 48 and 69 months. Hierarchical multiple regression was done to determine if speech ability accounted for a unique amount of variance in phonological awareness skill beyond what would be expected by developmental skills inclusive of receptive language and print and letter-sound knowledge. A range of skill in all areas of direct assessment was found. Children with limited speech were found to have emerging skills in print knowledge, letter-sound knowledge, and phonological awareness. Speech ability did not predict a significant amount of variance in phonological awareness beyond what would be expected by developmental skills of receptive language and print and letter-sound knowledge. Children with limited speech ability were found to have receptive language and letter-sound knowledge that supported the development of phonological awareness skills. This study provides implications for practitioners and researchers concerning the factors related to early reading development in children with limited speech ability and developmental disabilities.
[Validity assessment of a low level phonological processing test material in preschool children].
Ptok, M; Altwein, F
The BISC (Bielefelder Screening) is a German test to evaluate phonological skills believed to be a prerequisite for future reading and writing skills. BISC results may indicate an elevated risk for dyslexia. Our research group has put forward test material in order to specifically examine low-level phonological processing LLPP. In this study we analysed whether BISC and low-level phonological processing correlate. A retrospective correlation analysis was carried out on primary school children's test results of the BISC and the newly developed low-level phonological processing test material. Spearman's rho was 0.52 between total LLPP and total BISC. The subscales correlated with a rho below 0.5. Results indicate that a low level phonological processing and higher level phonological processing can be differentiated. Future studies will have to clarify whether these results can be used to construct specifically targeting therapy strategies and whether the LLPP test material can be used to assess the risk of subsequent dyslexia also. © Georg Thieme Verlag KG Stuttgart · New York.
Behavioral and electrophysiological evidence for early and automatic detection of phonological equivalence in variable speech inputs.
Kharlamov, Viktor; Campbell, Kenneth; Kazanina, Nina
Speech sounds are not always perceived in accordance with their acoustic-phonetic content. For example, an early and automatic process of perceptual repair, which ensures conformity of speech inputs to the listener's native language phonology, applies to individual input segments that do not exist in the native inventory or to sound sequences that are illicit according to the native phonotactic restrictions on sound co-occurrences. The present study with Russian and Canadian English speakers shows that listeners may perceive phonetically distinct and licit sound sequences as equivalent when the native language system provides robust evidence for mapping multiple phonetic forms onto a single phonological representation. In Russian, due to an optional but productive t-deletion process that affects /stn/ clusters, the surface forms [sn] and [stn] may be phonologically equivalent and map to a single phonological form /stn/. In contrast, [sn] and [stn] clusters are usually phonologically distinct in (Canadian) English. Behavioral data from identification and discrimination tasks indicated that [sn] and [stn] clusters were more confusable for Russian than for English speakers. The EEG experiment employed an oddball paradigm with nonwords [asna] and [astna] used as the standard and deviant stimuli. A reliable mismatch negativity response was elicited approximately 100 msec postchange in the English group but not in the Russian group. These findings point to a perceptual repair mechanism that is engaged automatically at a prelexical level to ensure immediate encoding of speech inputs in phonological terms, which in turn enables efficient access to the meaning of a spoken utterance.
Reading speed and phonological awareness deficits among Arabic-speaking children with dyslexia.
Layes, Smail; Lalonde, Robert; Rebaï, Mohamed
Although reading accuracy of isolated words and phonological awareness represent the main criteria of subtyping developmental dyslexia, there is increasing evidence that reduced reading speed also represents a defining characteristic. In the present study, reading speed and accuracy were measured in Arabic-speaking phonological and mixed dyslexic children matched with controls of the same age. Participants in third and fourth grades, aged from 9-10 to 9-8 years, were given single frequent and infrequent word and pseudo-word reading and phonological awareness tasks. Results showed that the group with dyslexia scored significantly lower than controls in accuracy and speed in reading tasks. Phonological and mixed dyslexic subgroups differed in infrequent and frequent word reading accuracy, the latter being worse. In contrast, the subgroups were comparable in pseudo-word identification and phonological awareness. Delayed phonological and recognition processes of infrequent and frequent words, respectively, were placed in the context of the dual route model of reading and the specific orthographic features of the Arabic language.

Word learning in adults with second language experience: Effects of phonological and referent familiarity
Kaushanskaya, Margarita; Yoo, Jeewon; Van Hecke, Stephanie
Purpose The goal of this research was to examine whether phonological familiarity exerts different effects on novel word learning for familiar vs. unfamiliar referents, and whether successful word-learning is associated with increased second-language experience. Method Eighty-one adult native English speakers with various levels of Spanish knowledge learned phonologically-familiar novel words (constructed using English sounds) or phonologically-unfamiliar novel words (constructed using non-English and non-Spanish sounds) in association with either familiar or unfamiliar referents. Retention was tested via a forced-choice recognition-task. A median-split procedure identified high-ability and low-ability word-learners in each condition, and the two groups were compared on measures of second-language experience. Results Findings suggest that the ability to accurately match newly-learned novel names to their appropriate referents is facilitated by phonological familiarity only for familiar referents but not for unfamiliar referents. Moreover, more extensive second-language learning experience characterized superior learners primarily in one word-learning condition: Where phonologically-unfamiliar novel words were paired with familiar referents. Conclusions Together, these findings indicate that phonological familiarity facilitates novel word learning only for familiar referents, and that experience with learning a second language may have a specific impact on novel vocabulary learning in adults.

Impaired reading comprehension in schizophrenia: evidence for underlying phonological processing deficits.
Arnott, Wendy; Sali, Lauren; Copland, David
The present study examined reading ability in high functioning people with schizophrenia. To this end, 16 people with schizophrenia who were living in the community and 12 matched controls completed tests of passage reading (comprehension, accuracy, and rate), word recognition, and phonological processing (phonological awareness, phonological memory and rapid naming) and ratings of reading self-concept and practices. Performance of the participants with schizophrenia was impaired relative to control participants on reading comprehension and rapid naming and relative to the population norms on phonological awareness, and rapid naming. In addition, self-rating data revealed that participants with schizophrenia had poorer perceptions of their reading ability and engaged in reading activities less frequently than their control counterparts. Consistent with earlier research, significant correlations were found between phonological awareness and reading comprehension. These findings expand on previous research in the area to suggest that community-based individuals with schizophrenia experience problems with reading comprehension that may have a phonological basis.

Training early literacy related skills: To which degree does a musical training contribute to phonological awareness development?
Directory of Open Access Journals (Sweden)
Sebastian Kempert
Full Text Available Well-developed phonological awareness skills are a core prerequisite for early literacy development. Although effective phonological awareness training programs exist, children at risk often do not reach similar levels of phonological awareness after the intervention as children with normally developed skills. Based on theoretical considerations and first promising results the present study explores effects of an early musical training in combination with a conventional phonological training in children with weak phonological awareness skills. Using a quasi-experimental pretest-posttest control group design and measurements across a period of two years, we tested the effects of two interventions: a consecutive combination of a musical and a phonological training and a phonological training alone. The design made it possible to disentangle effects of the musical training alone as well the effects of its combination with the phonological training. The outcome measures of these groups were compared with the control group with multivariate analyses, controlling for a number of background variables. The sample included N = 424 German-speaking children aged 4 to 5 years at the beginning of the study. We found a positive relationship between musical abilities and phonological awareness. Yet, whereas the well-established phonological training produced the expected effects, adding a musical training did not contribute significantly to phonological awareness development. Training effects were partly dependent on the initial level of phonological awareness. Possible reasons for the lack of training effects in the musical part of the combination condition as well as practical implications for early literacy education are discussed.
Improving Phonological Awareness in Parents of Children at Risk of Literacy Difficulties: A Preliminary Evaluation of the Boost Program
Boyes, Mark E.; Leitão, Suze; Claessen, Mary; Dzidic, Peta; Boyle, Gemma; Perry, Alison; Nayton, Mandy
Background Phonological awareness is an important skill underpinning the development of early literacy. Given the central role of parents in supporting the development of children's early literacy skills, and that poor parental phonological awareness is associated with poorer child literacy outcomes, it is possible that improving parent phonological awareness may aid literacy development for at-risk children. This study is a preliminary evaluation of a program aiming to improve phonologica...
Acoustic-Emergent Phonology in the Amplitude Envelope of Child-Directed Speech.
Directory of Open Access Journals (Sweden)
Victoria Leong
Full Text Available When acquiring language, young children may use acoustic spectro-temporal patterns in speech to derive phonological units in spoken language (e.g., prosodic stress patterns, syllables, phonemes. Children appear to learn acoustic-phonological mappings rapidly, without direct instruction, yet the underlying developmental mechanisms remain unclear. Across different languages, a relationship between amplitude envelope sensitivity and phonological development has been found, suggesting that children may make use of amplitude modulation (AM patterns within the envelope to develop a phonological system. Here we present the Spectral Amplitude Modulation Phase Hierarchy (S-AMPH model, a set of algorithms for deriving the dominant AM patterns in child-directed speech (CDS. Using Principal Components Analysis, we show that rhythmic CDS contains an AM hierarchy comprising 3 core modulation timescales. These timescales correspond to key phonological units: prosodic stress (Stress AM, ~2 Hz, syllables (Syllable AM, ~5 Hz and onset-rime units (Phoneme AM, ~20 Hz. We argue that these AM patterns could in principle be used by naïve listeners to compute acoustic-phonological mappings without lexical knowledge. We then demonstrate that the modulation statistics within this AM hierarchy indeed parse the speech signal into a primitive hierarchically-organised phonological system comprising stress feet (proto-words, syllables and onset-rime units. We apply the S-AMPH model to two other CDS corpora, one spontaneous and one deliberately-timed. The model accurately identified 72-82% (freely-read CDS and 90-98% (rhythmically-regular CDS stress patterns, syllables and onset-rime units. This in-principle demonstration that primitive phonology can be extracted from speech AMs is termed Acoustic-Emergent Phonology (AEP theory. AEP theory provides a set of methods for examining how early phonological development is shaped by the temporal modulation structure of speech across
Towards an Artificial Phonological Loop: An Assistive Device for Working Memory and Attentional Control
Directory of Open Access Journals (Sweden)
D. Bogen
Full Text Available We describe the initial development of an artificial phonological loop (APL, a new technology to assist individuals with impairment of the working memory system. The phonological loop, along with the visuospatial sketchpad, is one of the two slave short-term memory subsystems that comprise working memory, a cognitive function closely associated with the control of attention. In the phonological loop, phonological (speech information lasting for 1–2 second is maintained active by repetitive, subvocal (silent speech rehearsal. Deficits in working memory, specifically in the phonological loop, occur in many disorders, including attention-deficit disorder and Alzheimer's disease. In these disorders, it appears that the ability for phonological rehearsal is intact, but the regulation or triggering of the rehearsal process is inadequate, thus causing the contents of working memory to be lost. The purpose, then, of the APL is to facilitate the phonological loop by artificially extending the duration of phonological rehearsals. The APL mimics the natural phonological loop by providing audible vocal echoes to take the place of subvocal rehearsals. In this system, the user talks to him/herself in short (1–2 second phrases; the device records these phrases, stores them in electronic memory, and then repeats— i.e., echoes—the phrases multiple times over an extended period. Two versions of this device have been developed: the Echo-APL and the Rearticulation-APL. In the Echo-APL, only echoing is involved. In the Rearticulation-APL, however, the user re-vocalizes (rearticulates the phrase in response to an audible cue. The device repeats the cue until it detects (hears the re-vocalization. Future research and development of the APL will require extensive testing and careful evaluation of possible echo-schedules: the predefined program controlling inter-echo time intervals and echo-amplitude (echo loudness. The APL essentially exteriorizes the silent
How phonological awareness mediates the relation between working memory and word reading efficiency in children with dyslexia.
Knoop-van Campen, Carolien A N; Segers, Eliane; Verhoeven, Ludo
This study examined the relation between working memory, phonological awareness, and word reading efficiency in fourth-grade children with dyslexia. To test whether the relation between phonological awareness and word reading efficiency differed for children with dyslexia versus typically developing children, we assessed phonological awareness and word reading efficiency in 50 children with dyslexia (aged 9;10, 35 boys) and 613 typically developing children (aged 9;5, 279 boys). Phonological awareness was found to be associated with word reading efficiency, similar for children with dyslexia and typically developing children. To find out whether the relation between working memory and word reading efficiency in the group with dyslexia could be explained by phonological awareness, the children with dyslexia were also tested on working memory. Results of a mediation analysis showed a significant indirect effect of working memory on word reading efficiency via phonological awareness. Working memory predicted reading efficiency, via its relation with phonological awareness in children with dyslexia. This indicates that working memory is necessary for word reading efficiency via its impact on phonological awareness and that phonological awareness continues to be important for word reading efficiency in older children with dyslexia. © 2018 The Authors Dyslexia Published by John Wiley & Sons Ltd.
Deconstructing continuous flash suppression.
Yang, Eunice; Blake, Randolph
In this paper, we asked to what extent the depth of interocular suppression engendered by continuous flash suppression (CFS) varies depending on spatiotemporal properties of the suppressed stimulus and CFS suppressor. An answer to this question could have implications for interpreting the results in which CFS influences the processing of different categories of stimuli to different extents. In a series of experiments, we measured the selectivity and depth of suppression (i.e., elevation in contrast detection thresholds) as a function of the visual features of the stimulus being suppressed and the stimulus evoking suppression, namely, the popular "Mondrian" CFS stimulus (N. Tsuchiya & C. Koch, 2005). First, we found that CFS differentially suppresses the spatial components of the suppressed stimulus: Observers' sensitivity for stimuli of relatively low spatial frequency or cardinally oriented features was more strongly impaired in comparison to high spatial frequency or obliquely oriented stimuli. Second, we discovered that this feature-selective bias primarily arises from the spatiotemporal structure of the CFS stimulus, particularly within information residing in the low spatial frequency range and within the smooth rather than abrupt luminance changes over time. These results imply that this CFS stimulus operates by selectively attenuating certain classes of low-level signals while leaving others to be potentially encoded during suppression. These findings underscore the importance of considering the contribution of low-level features in stimulus-driven effects that are reported under CFS.
Preschool Phonological and Morphological Awareness As Longitudinal Predictors of Early Reading and Spelling Development in Greek.
Diamanti, Vassiliki; Mouzaki, Angeliki; Ralli, Asimina; Antoniou, Faye; Papaioannou, Sofia; Protopapas, Athanassios
Different language skills are considered fundamental for successful reading and spelling acquisition. Extensive evidence has highlighted the central role of phonological awareness in early literacy experiences. However, many orthographic systems also require the contribution of morphological awareness. The goal of this study was to examine the morphological and phonological awareness skills of preschool children as longitudinal predictors of reading and spelling ability by the end of first grade, controlling for the effects of receptive and expressive vocabulary skills. At Time 1 preschool children from kindergartens in the Greek regions of Attika, Crete, Macedonia, and Thessaly were assessed on tasks tapping receptive and expressive vocabulary, phonological awareness (syllable and phoneme), and morphological awareness (inflectional and derivational). Tasks were administered through an Android application for mobile devices (tablets) featuring automatic application of ceiling rules. At Time 2 one year later the same children attending first grade were assessed on measures of word and pseudoword reading, text reading fluency, text reading comprehension, and spelling. Complete data from 104 children are available. Hierarchical linear regression and commonality analyses were conducted for each outcome variable. Reading accuracy for both words and pseudowords was predicted not only by phonological awareness, as expected, but also by morphological awareness, suggesting that understanding the functional role of word parts supports the developing phonology-orthography mappings. However, only phonological awareness predicted text reading fluency at this age. Longitudinal prediction of reading comprehension by both receptive vocabulary and morphological awareness was already evident at this age, as expected. Finally, spelling was predicted by preschool phonological awareness, as expected, as well as by morphological awareness, the contribution of which is expected to
Fronto-parietal contributions to phonological processes in successful artificial grammar learning

Full Text Available Sensitivity to regularities plays a crucial role in the acquisition of various linguistic features from spoken language input. Artificial grammar (AG learning paradigms explore pattern recognition abilities in a set of structured sequences (i.e. of syllables or letters. In the present study, we investigated the functional underpinnings of learning phonological regularities in auditorily presented syllable sequences. While previous neuroimaging studies either focused on functional differences between the processing of correct vs. incorrect sequences or between different levels of sequence complexity, here the focus is on the neural foundation of the actual learning success. During functional magnetic resonance imaging (fMRI, participants were exposed to a set of syllable sequences with an underlying phonological rule system, known to ensure performance differences between participants. We expected that successful learning and rule application would require phonological segmentation and phoneme comparison. As an outcome of four alternating learning and test fMRI sessions, participants split into successful learners and non-learners. Relative to non-learners, successful learners showed increased task-related activity in a fronto-parietal network of brain areas encompassing the left lateral premotor cortex as well as bilateral superior and inferior parietal cortices during both learning and rule application. These areas were previously associated with phonological segmentation, phoneme comparison and verbal working memory. Based on these activity patterns and the phonological strategies for rule acquisition and application, we argue that successful learning and processing of complex phonological rules in our paradigm is mediated via a fronto-parietal network for phonological processes.
The contribution of phonological knowledge, memory, and language background to reading comprehension in deaf populations
Hirshorn, Elizabeth A.; Dye, Matthew W. G.; Hauser, Peter; Supalla, Ted R.; Bavelier, Daphne
While reading is challenging for many deaf individuals, some become proficient readers. Little is known about the component processes that support reading comprehension in these individuals. Speech-based phonological knowledge is one of the strongest predictors of reading comprehension in hearing individuals, yet its role in deaf readers is controversial. This could reflect the highly varied language backgrounds among deaf readers as well as the difficulty of disentangling the relative contribution of phonological versus orthographic knowledge of spoken language, in our case 'English,' in this population. Here we assessed the impact of language experience on reading comprehension in deaf readers by recruiting oral deaf individuals, who use spoken English as their primary mode of communication, and deaf native signers of American Sign Language. First, to address the contribution of spoken English phonological knowledge in deaf readers, we present novel tasks that evaluate phonological versus orthographic knowledge. Second, the impact of this knowledge, as well as memory measures that rely differentially on phonological (serial recall) and semantic (free recall) processing, on reading comprehension was evaluated. The best predictor of reading comprehension differed as a function of language experience, with free recall being a better predictor in deaf native signers than in oral deaf. In contrast, the measures of English phonological knowledge, independent of orthographic knowledge, best predicted reading comprehension in oral deaf individuals. These results suggest successful reading strategies differ across deaf readers as a function of their language experience, and highlight a possible alternative route to literacy in deaf native signers. Highlights: 1. Deaf individuals vary in their orthographic and phonological knowledge of English as a function of their language experience. 2. Reading comprehension was best predicted by different factors in oral deaf and

Automated Intelligibility Assessment of Pathological Speech Using Phonological Features
Directory of Open Access Journals (Sweden)
Catherine Middag
Full Text Available It is commonly acknowledged that word or phoneme intelligibility is an important criterion in the assessment of the communication efficiency of a pathological speaker. People have therefore put a lot of effort in the design of perceptual intelligibility rating tests. These tests usually have the drawback that they employ unnatural speech material (e.g., nonsense words and that they cannot fully exclude errors due to listener bias. Therefore, there is a growing interest in the application of objective automatic speech recognition technology to automate the intelligibility assessment. Current research is headed towards the design of automated methods which can be shown to produce ratings that correspond well with those emerging from a well-designed and well-performed perceptual test. In this paper, a novel methodology that is built on previous work (Middag et al., 2008 is presented. It utilizes phonological features, automatic speech alignment based on acoustic models that were trained on normal speech, context-dependent speaker feature extraction, and intelligibility prediction based on a small model that can be trained on pathological speech samples. The experimental evaluation of the new system reveals that the root mean squared error of the discrepancies between perceived and computed intelligibilities can be as low as 8 on a scale of 0 to 100.
English Language Teaching: phonetics, phonology and auditory processing contributions.
Araújo, Letícia Maria Martins; Feniman, Mariza Ribeiro; Carvalho, Fernanda Ribeiro Pinto de; Lopes-Herrera, Simone Aparecida
interrelation of phonetics, phonology and auditory processing in English Language Teaching. to determine whether prior contact with English phonetics favors general learning of this language (L2), i.e. second language, in Portuguese speakers; to verify performance of these individuals in an auditory processing test prior to and after being taught L2. participants of the study were eight college students who had only studied English in high school. These participants were divided into two groups: control group - were only enrolled in English classes; experimental group - were enrolled in English phonetic classes prior to their enrollment in English classes. Participants were submitted to an auditory processing test and to an oral test in English (Oral Test) prior to and after the classes. Data were analyzed in the same way, i.e. prior to and after the classes. these were expressed statistically by T-Student's test. Analyses indicated no difference in performance between groups. Scores indicated better performance of the control group for answering questions in English in the Oral Test. The experimental group had better performance in the auditory processing test after being enrolled to English phonetic classes and English course. prior basic knowledge of English did not enhance general learning (improvement in pronunciation) of the second language, however, it improved the ability of temporal processing in the used test.
Speech rate and fluency in children with phonological disorder.
Novaes, Priscila Maronezi; Nicolielo-Carrilho, Ana Paola; Lopes-Herrera, Simone Aparecida
To identify and describe the speech rate and fluency of children with phonological disorder (PD) with and without speech-language therapy. Thirty children, aged 5-8 years old, both genders, were divided into three groups: experimental group 1 (G1) — 10 children with PD in intervention; experimental group 2 (G2) — 10 children with PD without intervention; and control group (CG) — 10 children with typical development. Speech samples were collected and analyzed according to parameters of specific protocol. The children in CG had higher number of words per minute compared to those in G1, which, in turn, performed better in this aspect compared to children in G2. Regarding the number of syllables per minute, the CG showed the best result. In this aspect, the children in G1 showed better results than those in G2. Comparing children's performance in the assessed groups regarding the tests, those with PD in intervention had higher time of speech sample and adequate speech rate, which may be indicative of greater auditory monitoring of their own speech as a result of the intervention.
Music Training Increases Phonological Awareness and Reading Skills in Developmental Dyslexia: A Randomized Control Trial.
Flaugnacco, Elena; Lopez, Luisa; Terribili, Chiara; Montico, Marcella; Zoia, Stefania; Schön, Daniele
There is some evidence for a role of music training in boosting phonological awareness, word segmentation, working memory, as well as reading abilities in children with typical development. Poor performance in tasks requiring temporal processing, rhythm perception and sensorimotor synchronization seems to be a crucial factor underlying dyslexia in children. Interestingly, children with dyslexia show deficits in temporal processing, both in language and in music. Within this framework, we test the hypothesis that music training, by improving temporal processing and rhythm abilities, improves phonological awareness and reading skills in children with dyslexia. The study is a prospective, multicenter, open randomized controlled trial, consisting of test, rehabilitation and re-test (ID NCT02316873). After rehabilitation, the music group (N = 24) performed better than the control group (N = 22) in tasks assessing rhythmic abilities, phonological awareness and reading skills. This is the first randomized control trial testing the effect of music training in enhancing phonological and reading abilities in children with dyslexia. The findings show that music training can modify reading and phonological abilities even when these skills are severely impaired. Through the enhancement of temporal processing and rhythmic skills, music might become an important tool in both remediation and early intervention programs.Trial Registration: ClinicalTrials.gov NCT02316873

Speech Recognition in Adults With Cochlear Implants: The Effects of Working Memory, Phonological Sensitivity, and Aging.
Moberly, Aaron C; Harris, Michael S; Boyce, Lauren; Nittrouer, Susan
Models of speech recognition suggest that "top-down" linguistic and cognitive functions, such as use of phonotactic constraints and working memory, facilitate recognition under conditions of degradation, such as in noise. The question addressed in this study was what happens to these functions when a listener who has experienced years of hearing loss obtains a cochlear implant. Thirty adults with cochlear implants and 30 age-matched controls with age-normal hearing underwent testing of verbal working memory using digit span and serial recall of words. Phonological capacities were assessed using a lexical decision task and nonword repetition. Recognition of words in sentences in speech-shaped noise was measured. Implant users had only slightly poorer working memory accuracy than did controls and only on serial recall of words; however, phonological sensitivity was highly impaired. Working memory did not facilitate speech recognition in noise for either group. Phonological sensitivity predicted sentence recognition for implant users but not for listeners with normal hearing. Clinical speech recognition outcomes for adult implant users relate to the ability of these users to process phonological information. Results suggest that phonological capacities may serve as potential clinical targets through rehabilitative training. Such novel interventions may be particularly helpful for older adult implant users.
Spelling Errors in French-speaking Children with Dyslexia: Phonology May Not Provide the Best Evidence.
Daigle, Daniel; Costerg, Agnès; Plisson, Anne; Ruberto, Noémia; Varin, Joëlle
For children with dyslexia, learning to write constitutes a great challenge. There has been consensus that the explanation for these learners' delay is related to a phonological deficit. Results from studies designed to describe dyslexic children's spelling errors are not always as clear concerning the role of phonological processes as those found in reading studies. In irregular languages like French, spelling abilities involve other processes than phonological processes. The main goal of this study was to describe the relative contribution of these other processes in dyslexic children's spelling ability. In total, 32 francophone dyslexic children with a mean age of 11.4 years were compared with 24 reading-age matched controls (RA) and 24 chronological-age matched controls (CA). All had to write a text that was analysed at the graphemic level. All errors were classified as either phonological, morphological, visual-orthographic or lexical. Results indicated that dyslexic children's spelling ability lagged behind not only that of the CA group but also of the RA group. Because the majority of errors, in all groups, could not be explained by inefficiency of phonological processing, the importance of visual knowledge/processes will be discussed as a complementary explanation of dyslexic children's delay in writing.

Phonological working memory and auditory processing speed in children with specific language impairment
Directory of Open Access Journals (Sweden)
Fatemeh Haresabadi
Full Text Available Background and Aim: Specific language impairment (SLI, one variety of developmental language disorder, has attracted much interest in recent decades. Much research has been conducted to discover why some children have a specific language impairment. So far, research has failed to identify a reason for this linguistic deficiency. Some researchers believe language disorder causes defects in phonological working memory and affects auditory processing speed. Therefore, this study reviews the results of research investigating these two factors in children with specific language impairment.Recent Findings: Studies have shown that children with specific language impairment face constraints in phonological working memory capacity. Memory deficit is one possible cause of linguistic disorder in children with specific language impairment. However, in these children, disorder in information processing speed is observed, especially regarding the auditory aspect.Conclusion: Much more research is required to adequately explain the relationship between phonological working memory and auditory processing speed with language. However, given the role of phonological working memory and auditory processing speed in language acquisition, a focus should be placed on phonological working memory capacity and auditory processing speed in the assessment and treatment of children with a specific language impairment.

Farzad Weisi
Full Text Available Introduction: Advanced phonological skills are important for the acquisition of reading skills. Children with hearing impairment have reading skills are weaker than others because of auditory inputs and due to the defect in phonological skills. The use of hearing aids and cochlear implants help to collect information on people who are hard of hearing.Material and Methods: This descriptive - analytic study was done on 12 children with cochlear implant and 12 children with hearing aids that was selected from second grades students of Tehran primary schools. Children's phonological performance was assessed by phonological subtests of Nama reading test and the data were analyzed using SPSS 16.Results: The results showed that the means of scores of children with cochlear implants in Rhyme task were significantly greater than the children with hearing aids (P=0.034. But in means of scores of Phone deletion and Nonword reading tasks were not significant different between two groups (P=0.919, P=0.670.Discussion: Cochlear implant with accessibility auditory inputs can facilitated the acquisition of phonological awareness skills in hearing loss children. But whereas the other language inputs such as sight and touch input helped to developing these skills, children with hearing aids too also can acquisition these skills.
Reconciling phonological neighborhood effects in speech production through single trial analysis.
Sadat, Jasmin; Martin, Clara D; Costa, Albert; Alario, F-Xavier
A crucial step for understanding how lexical knowledge is represented is to describe the relative similarity of lexical items, and how it influences language processing. Previous studies of the effects of form similarity on word production have reported conflicting results, notably within and across languages. The aim of the present study was to clarify this empirical issue to provide specific constraints for theoretical models of language production. We investigated the role of phonological neighborhood density in a large-scale picture naming experiment using fine-grained statistical models. The results showed that increasing phonological neighborhood density has a detrimental effect on naming latencies, and re-analyses of independently obtained data sets provide supplementary evidence for this effect. Finally, we reviewed a large body of evidence concerning phonological neighborhood density effects in word production, and discussed the occurrence of facilitatory and inhibitory effects in accuracy measures. The overall pattern shows that phonological neighborhood generates two opposite forces, one facilitatory and one inhibitory. In cases where speech production is disrupted (e.g. certain aphasic symptoms), the facilitatory component may emerge, but inhibitory processes dominate in efficient naming by healthy speakers. These findings are difficult to accommodate in terms of monitoring processes, but can be explained within interactive activation accounts combining phonological facilitation and lexical competition.

Immediate memory for pseudowords and phonological awareness are associated in adults and pre-reading children
Clark, Nathaniel B.; McRoberts, Gerald W.; Van Dyke, Julie A.; Shankweiler, Donald P.; Braze, David
This study investigated phonological components of reading skill at two ages, using a novel pseudoword repetition task for assessing phonological memory (PM). Pseudowords were designed to incorporate control over segmental, prosodic and lexical features. In experiment 1, the materials were administered to 3- and 4-year-old children together with a standardized test of phonological awareness (PA). PA and pseudoword repetition showed a moderate positive correlation, independent of age. Experiment 2, which targeted young adults, employed the same pseudoword materials, with a different administration protocol, together with standardized indices of PA, other memory measures, and decoding skill. The results showed moderate to strong positive correlations among our novel pseudoword repetition task, measures of PM and PA, and decoding. Together, the findings demonstrate the feasibility of assessing PM with the same carefully controlled materials at widely spaced points in age, adding to present resources for assessing phonological memory and better enabling future studies to map the development of relationships among phonological capabilities in both typically developing children and those with language-related impairments.

Zahra Ilkhani
Full Text Available Human immunodeficiency virus (HIV is a viral disease with immunodeficiency in human. So, it can involve different areas such as language, speech, motor and memory. The present research, as a case report, introducing the characteristics of phonological processes of a child who had Aids and lived in a nursery through referring and professional assessing in a speech therapy clinic. The child was a 4 year old boy who was in HIV base on blood test. Speech skills was assessed based on DEAP and language assessment was analyzed according to TOLD-P3. He talked with single word. He used two words sentences rarely. According to language assessment (TOLD-P3, semantic, syntax and phonology features were tested. So he was in emerging language stage. Also his expressive language was lower than his perceive language. In addition, based on DEAP-P test, phonological process of substitution type has been recognized most. Also, the most of the substitution phonological process which accrued have been velar fronting. This study showed that the most phonological process in a child with HIV was the process of substitution. It may be a risk factor for decreasing speech intelligibility. With regard to the results of the present research that showed that the subject had the disorder and there are limited researches in this area,
Influences of Phonological Context on Tense Marking in Spanish–English Dual Language Learners
Barlow, Jessica A.; Potapova, Irina; Pruitt-Lord, Sonja
Purpose The emergence of tense-morpheme marking during language acquisition is highly variable, which confounds the use of tense marking as a diagnostic indicator of language impairment in linguistically diverse populations. In this study, we seek to better understand tense-marking patterns in young bilingual children by comparing phonological influences on marking of 2 word-final tense morphemes. Method In spontaneous connected speech samples from 10 Spanish–English dual language learners aged 56–66 months (M = 61.7, SD = 3.4), we examined marking rates of past tense -ed and third person singular -s morphemes in different environments, using multiple measures of phonological context. Results Both morphemes were found to exhibit notably contrastive marking patterns in some contexts. Each was most sensitive to a different combination of phonological influences in the verb stem and the following word. Conclusions These findings extend existing evidence from monolingual speakers for the influence of word-final phonological context on morpheme production to a bilingual population. Further, novel findings not yet attested in previous research support an expanded consideration of phonological context in clinical decision making and future research related to word-final morphology.

The effect of working memory load on semantic illusions: what the phonological loop and central executive have to contribute.
Büttner, Anke Caroline
When asked how many animals of each kind Moses took on the Ark, most people respond with "two" despite the substituted name (Moses for Noah) in the question. Possible explanations for semantic illusions appear to be related to processing limitations such as those of working memory. Indeed, individual working memory capacity has an impact upon how sentences containing substitutions are processed. This experiment examined further the role of working memory in the occurrence of semantic illusions using a dual-task working memory load approach. Participants verified statements while engaging in either articulatory suppression or random number generation. Secondary task type had a significant effect on semantic illusion rate, but only when comparing the control condition to the two dual-task conditions. Furthermore, secondary task performance in the random number generation condition declined, suggesting a tradeoff between tasks. Response time analyses also showed a different pattern of processing across the conditions. The findings suggest that the phonological loop plays a role in representing semantic illusion sentences coherently and in monitoring for details, while the role of the central executive is to assist gist-processing of sentences. This usually efficient strategy leads to error in the case of semantic illusions.
Phonological skills as predictor of reading success: An investigation of emergent bilingual Northern Sotho/English learners
Directory of Open Access Journals (Sweden)
Wilsenach, Carien
Full Text Available The relationship between phonological skills and reading has not been studied extensively in the African languages spoken in South Africa. This study focuses on phonological skills and reading in emergent bilingual Northern Sotho/English learners. Fifty Grade 3 learners (all native speakers of Northern Sotho were tested on non-word repetition skills, syllable awareness, phonological working memory and reading. The learners fell into two groups: group 1 attended a school where English was the medium of instruction from the first grade, while group 2 attended a school where literacy instruction took place in Northern Sotho for the first three years of schooling. The results indicate that there is a significant correlation between phonological skills and reading in Northern Sotho. Furthermore, group 2 performed significantly better on all of the phonological measures (with the exception of phonological working memory and reading measures. The findings suggest that a complete lack of mother tongue instruction can influence phonological and literacy development negatively. The study also suggests that the absence of mother tongue literacy instruction causes stagnation in the development of phonological processing skills in the mother tongue.

The roles of long-term phonotactic and lexical prosodic knowledge in phonological short-term memory.
Tanida, Yuki; Ueno, Taiji; Lambon Ralph, Matthew A; Saito, Satoru
Many previous studies have explored and confirmed the influence of long-term phonological representations on phonological short-term memory. In most investigations, phonological effects have been explored with respect to phonotactic constraints or frequency. If interaction between long-term memory and phonological short-term memory is a generalized principle, then other phonological characteristics-that is, suprasegmental aspects of phonology-should also exert similar effects on phonological short-term memory. We explored this hypothesis through three immediate serial-recall experiments that manipulated Japanese nonwords with respect to lexical prosody (pitch-accent type, reflecting suprasegmental characteristics) as well as phonotactic frequency (reflecting segmental characteristics). The results showed that phonotactic frequency affected the retention not only of the phonemic sequences, but also of pitch-accent patterns, when participants were instructed to recall both the phoneme sequence and accent pattern of nonwords. In addition, accent pattern typicality influenced the retention of the accent pattern: Typical accent patterns were recalled more accurately than atypical ones. These results indicate that both long-term phonotactic and lexical prosodic knowledge contribute to phonological short-term memory performance.

Do children with dyslexia and/or specific language impairment compensate for place assimilation? Insight into phonological grammar and representations.
Marshall, Chloe R; Ramus, Franck; van der Lely, Heather
English speakers have to recognize, for example, that te[m] in te[m] pens is a form of ten, despite place assimilation of the nasal consonant. Children with dyslexia and specific language impairment (SLI) are commonly proposed to have a phonological deficit, and we investigate whether that deficit extends to place assimilation, as a way of probing phonological representations and phonological grammar. Children with SLI plus dyslexia, SLI only, and dyslexia only listened to sentences containing a target word in different assimilatory contexts-viable, unviable, and no change-and pressed a button to report hearing the target. The dyslexia-only group did not differ from age-matched controls, but the SLI groups showed more limited ability to accurately identify words within sentences. Once this factor was taken into account, the groups did not differ in their ability to compensate for assimilation. The results add to a growing body of evidence that phonological representations are not necessarily impaired in dyslexia. SLI children's results suggest that they too are sensitive to this aspect of phonological grammar, but are more liberal in their acceptance of alternative phonological forms of words. Furthermore, these children's ability to reject alternative phonological forms seems to be primarily limited by their vocabulary size and phonological awareness abilities.

The MSNH group showed…
Phonological abilities in literacy-impaired children: Brain potentials reveal deficient phoneme discrimination, but intact prosodic processing
Directory of Open Access Journals (Sweden)
Claudia Männel
Full Text Available Intact phonological processing is crucial for successful literacy acquisition. While individuals with difficulties in reading and spelling (i.e., developmental dyslexia are known to experience deficient phoneme discrimination (i.e., segmental phonology, findings concerning their prosodic processing (i.e., suprasegmental phonology are controversial. Because there are no behavior-independent studies on the underlying neural correlates of prosodic processing in dyslexia, these controversial findings might be explained by different task demands. To provide an objective behavior-independent picture of segmental and suprasegmental phonological processing in impaired literacy acquisition, we investigated event-related brain potentials during passive listening in typically and poor-spelling German school children. For segmental phonology, we analyzed the Mismatch Negativity (MMN during vowel length discrimination, capturing automatic auditory deviancy detection in repetitive contexts. For suprasegmental phonology, we analyzed the Closure Positive Shift (CPS that automatically occurs in response to prosodic boundaries. Our results revealed spelling group differences for the MMN, but not for the CPS, indicating deficient segmental, but intact suprasegmental phonological processing in poor spellers. The present findings point towards a differential role of segmental and suprasegmental phonology in literacy disorders and call for interventions that invigorate impaired literacy by utilizing intact prosody in addition to training deficient phonemic awareness.
The Role of Music Perception in Predicting Phonological Awareness in Five- and Six-Year-Old Children
Lathroum, Linda M.
The purpose of this study was to examine the role of music perception in predicting phonological awareness in five- and six-year-old children. This study was based on the hypothesis that music perception and phonological awareness appear to have parallel auditory perceptual mechanisms. Previous research investigating the relationship between these…

Children's phonological awareness was assessed at the beginning and end of preschool. Mothers reported the frequency with which they read books…
Emergence of the neural network underlying phonological processing from the prereading to the emergent reading stage: A longitudinal study.
Yu, Xi; Raney, Talia; Perdue, Meaghan V; Zuk, Jennifer; Ozernov-Palchik, Ola; Becker, Bryce L C; Raschle, Nora M; Gaab, Nadine
Numerous studies have shown that phonological skills are critical for successful reading acquisition. However, how the brain network supporting phonological processing evolves and how it supports the initial course of learning to read is largely unknown. Here, for the first time, we characterized the emergence of the phonological network in 28 children over three stages (prereading, beginning reading, and emergent reading) longitudinally. Across these three time points, decreases in neural activation in the left inferior parietal cortex (LIPC) were observed during an audiovisual phonological processing task, suggesting a specialization process in response to reading instruction/experience. Furthermore, using the LIPC as the seed, a functional network consisting of the left inferior frontal, left posterior occipitotemporal, and right angular gyri was identified. The connection strength in this network co-developed with the growth of phonological skills. Moreover, children with above-average gains in phonological processing showed a significant developmental increase in connection strength in this network longitudinally, while children with below-average gains in phonological processing exhibited the opposite trajectory. Finally, the connection strength between the LIPC and the left posterior occipitotemporal cortex at the prereading level significantly predicted reading performance at the emergent reading stage. Our findings highlight the importance of the early emerging phonological network for reading development, providing direct evidence for the Interactive Specialization Theory and neurodevelopmental models of reading. © 2018 Wiley Periodicals, Inc.
The Effect of Dual N-Back Task Training on Phonological Memory Expansion in Adult EFL Learners at the Beginner Level
Farvardin, Mohammad Taghi; Afghari, Akbar; Koosha, Mansour
One of the most influential models of working memory (WM) is the one developed by Baddeley (1986, 2000, 2003) which views WM comprising several components--a central executive, an episodic buffer, the visuo-spatial sketchpad, and the phonological loop. The phonological loop or phonological memory (PM) deals with the temporary storage of verbal and…
Phonological and orthographic influences in the bouba-kiki effect.
Cuskley, Christine; Simner, Julia; Kirby, Simon
We examine a high-profile phenomenon known as the bouba-kiki effect, in which non-word names are assigned to abstract shapes in systematic ways (e.g. rounded shapes are preferentially labelled bouba over kiki). In a detailed evaluation of the literature, we show that most accounts of the effect point to predominantly or entirely iconic cross-sensory mappings between acoustic or articulatory properties of sound and shape as the mechanism underlying the effect. However, these accounts have tended to confound the acoustic or articulatory properties of non-words with another fundamental property: their written form. We compare traditional accounts of direct audio or articulatory-visual mapping with an account in which the effect is heavily influenced by matching between the shapes of graphemes and the abstract shape targets. The results of our two studies suggest that the dominant mechanism underlying the effect for literate subjects is matching based on aligning letter curvature and shape roundedness (i.e. non-words with curved letters are matched to round shapes). We show that letter curvature is strong enough to significantly influence word-shape associations even in auditory tasks, where written word forms are never presented to participants. However, we also find an additional phonological influence in that voiced sounds are preferentially linked with rounded shapes, although this arises only in a purely auditory word-shape association task. We conclude that many previous investigations of the bouba-kiki effect may not have given appropriate consideration or weight to the influence of orthography among literate subjects.
Phonologic-graphemic transcodifier for Portuguese Language spoken in Brazil (PLB)
Fragadasilva, Francisco Jose; Saotome, Osamu; Deoliveira, Carlos Alberto
An automatic speech-to-text transformer system, suited to unlimited vocabulary, is presented. The basic acoustic unit considered are the allophones of the phonemes corresponding to the Portuguese language spoken in Brazil (PLB). The input to the system is a phonetic sequence, from a former step of isolated word recognition of slowly spoken speech. In a first stage, the system eliminates phonetic elements that don't belong to PLB. Using knowledge sources such as phonetics, phonology, orthography, and PLB specific lexicon, the output is a sequence of written words, ordered by probabilistic criterion that constitutes the set of graphemic possibilities to that input sequence. Pronunciation differences of some regions of Brazil are considered, but only those that cause differences in phonological transcription, because those of phonetic level are absorbed, during the transformation to phonological level. In the final stage, all possible written words are analyzed for orthography and grammar point of view, to eliminate the incorrect ones.
The role of phonology, morphology, and orthography in English and Russian spelling.
Boulware-Gooden, Regina; Joshi, R Malatesha; Grigorenko, Elena
The purpose of the present study was to explore the role of phonology, morphology and orthography in predicting the spelling performance in English-speaking and Russian-speaking children. Tests that tap phonology, morphology and orthography were administered to students in grades 4 and 6 in the USA and Russia. Multiple regression analyses showed that phonology and morphology contributed more for spelling of English words while orthography and morphology contributed more to the spelling of Russian words. The results are explained in terms of the orthographic nature of English and Russian languages as well as the instructional practices and the importance of morphology in spelling in both the languages.

The Role of Consciousness in the Phonological Loop: Hidden in Plain Sight
Directory of Open Access Journals (Sweden)
Bradley Russell Buchsbaum
Full Text Available We know from everyday experience that when we need to keep a small amount of verbal information in mind for a short period, an effective cognitive strategy is to silently rehearse the words. This basic cognitive strategy has been elegantly codified in Baddeley and colleagues model of verbal working memory, the phonological loop. Here we explore how the intuitive appeal of the phonological loop is grounded in the phenomenological experience of subvocal rehearsal as consisting of an interaction between an inner voice and an inner ear. We focus particularly on how our intuitions about the phenomenological experience of inner speech might constrain or otherwise inform the functional architecture of information processing models of verbal working memory such as the phonological loop; and how, indeed, how ideas about consciousness may offer alternative explanations for the dual nature of inner speech in verbal working memory.
Whole-Word Phonological Representations of Disyllabic Words in the Chinese Lexicon: Data From Acquired Dyslexia
Directory of Open Access Journals (Sweden)
Sam-Po Law
Full Text Available This study addresses the issue of the existence of whole-word phonological representations of disyllabic and multisyllabic words in the Chinese mental lexicon. A Cantonese brain-injured dyslexic individual with semantic deficits, YKM, was assessed on his abilities to read aloud and to comprehend disyllabic words containing homographic heterophonous characters, the pronunciation of which can only be disambiguated in word context. Superior performance on reading to comprehension was found. YKM could produce the target phonological forms without understanding the words. The dissociation is taken as evidence for whole-word representations for these words at the phonological level. The claim is consistent with previous account for discrepancy of the frequencies of tonal errors between reading aloud and object naming in Cantonese reported of another case study of similar deficits. Theoretical arguments for whole-word form representations for all multisyllabic Chinese words are also discussed.
The Stroop effect in English-Japanese bilinguals: the effect of phonological similarity.
Sumiya, Hiromi; Healy, Alice F
English-Japanese bilinguals performed a Stroop color-word interference task with both English and Japanese stimuli and responded in both English and Japanese. The Japanese stimuli were either the traditional color terms (TCTs) written in Hiragana or loanwords (LWs) from English written in Katakana. Both within-language and between-language interference were found for all combinations of stimuli and responses. The between-language interference was larger for Katakana LWs (phonologically similar to English) than for Hiragana TCTs, especially with Japanese responses. The magnitude of this phonological effect increased with self-rated reading fluency in Japanese. Overall responding was slower and the Stroop effect larger with English than with Japanese stimuli. These results suggest that unintentional lexical access elicits automatic phonological processing even with intermediate-level reading proficiency.

Maysa Luchesi Cera
Full Text Available Abstract The literature on apraxia of speech describes the types and characteristics of phonological errors in this disorder. In general, phonemes affected by errors are described, but the distinctive features involved have not yet been investigated. Objective: To analyze the features involved in substitution errors produced by Brazilian-Portuguese speakers with apraxia of speech. Methods: 20 adults with apraxia of speech were assessed. Phonological analysis of the distinctive features involved in substitution type errors was carried out using the protocol for the evaluation of verbal and non-verbal apraxia. Results: The most affected features were: voiced, continuant, high, anterior, coronal, posterior. Moreover, the mean of the substitutions of marked to markedness features was statistically greater than the markedness to marked features. Conclusions: This study contributes toward a better characterization of the phonological errors found in apraxia of speech, thereby helping to diagnose communication disorders and the selection criteria of phonemes for rehabilitation in these patients.
Schizophrenia as failure of left hemispheric dominance for the phonological component of language.
Angrilli, Alessandro; Spironelli, Chiara; Elbert, Thomas; Crow, Timothy J; Marano, Gianfranco; Stegagno, Luciano
T. J. Crow suggested that the genetic variance associated with the evolution in Homo sapiens of hemispheric dominance for language carries with it the hazard of the symptoms of schizophrenia. Individuals lacking the typical left hemisphere advantage for language, in particular for phonological components, would be at increased risk of the typical symptoms such as auditory hallucinations and delusions. Twelve schizophrenic patients treated with low levels of neuroleptics and twelve matched healthy controls participated in an event-related potential experiment. Subjects matched word-pairs in three tasks: rhyming/phonological, semantic judgment and word recognition. Slow evoked potentials were recorded from 26 scalp electrodes, and a laterality index was computed for anterior and posterior regions during the inter stimulus interval. During phonological processing individuals with schizophrenia failed to achieve the left hemispheric dominance consistently observed in healthy controls. The effect involved anterior (fronto-temporal) brain regions and was specific for the Phonological task; group differences were small or absent when subjects processed the same stimulus material in a Semantic task or during Word Recognition, i.e. during tasks that typically activate more widespread areas in both hemispheres. We show for the first time how the deficit of lateralization in the schizophrenic brain is specific for the phonological component of language. This loss of hemispheric dominance would explain typical symptoms, e.g. when an individual's own thoughts are perceived as an external intruding voice. The change can be interpreted as a consequence of "hemispheric indecision", a failure to segregate phonological engrams in one hemisphere.

Full Text Available The aim of this study was to determine characteristics of phonological awareness of stuttering children and children with fluent speech. The sample consisted of 64 children, between 56 and 83 months old (4 years and 8 months to 6 years and 11 months. Examinees were divided in two groups. The first group consisted of 32 stuttering children, 19 males, and 13 females. The control group consisted of 32 children with fluent speech, whose age and sex were equal to the age and sex of the children in the experimental group. The research was conducted in preschools and primary schools in Tuzla and Una-Sana Canton in Bosnia and Herzegovina. The subjects were examined with 7 subtests (syllable and phoneme blending abilities, ability to rhyme, phoneme segmentation, phoneme deletion, phoneme transposition and spoonerisms. Each of the subtest scores, which index a variety of phonological awareness abilities, was examined separately. Phonological awareness score is the total score which relates to a common result that the subjects achieved on these 7 individual subtests. The results showed that there were no statistically significant differences between stuttering children and their peers with fluent speech in relation to Phonological awareness score. The examination of differences between stuttering and non-stuttering children in individual variables, which describe phonological awareness, showed that there was statistically significant difference in the ability to rhyme between these two subjects groups. T-test was used for examination of the differences between the male stuttering children and their fluent peers, and also female stuttering children and their fluent peers for the phonological awareness variables. The results exhibited statistically significant differences in the variable Rhyme between the male stuttering children and their fluent peers. In addition, we examined the ability of phonemic analysis of children who stutter and children with fluent
Preschool Phonological and Morphological Awareness As Longitudinal Predictors of Early Reading and Spelling Development in Greek
Directory of Open Access Journals (Sweden)
Vassiliki Diamanti
Full Text Available Different language skills are considered fundamental for successful reading and spelling acquisition. Extensive evidence has highlighted the central role of phonological awareness in early literacy experiences. However, many orthographic systems also require the contribution of morphological awareness. The goal of this study was to examine the morphological and phonological awareness skills of preschool children as longitudinal predictors of reading and spelling ability by the end of first grade, controlling for the effects of receptive and expressive vocabulary skills. At Time 1 preschool children from kindergartens in the Greek regions of Attika, Crete, Macedonia, and Thessaly were assessed on tasks tapping receptive and expressive vocabulary, phonological awareness (syllable and phoneme, and morphological awareness (inflectional and derivational. Tasks were administered through an Android application for mobile devices (tablets featuring automatic application of ceiling rules. At Time 2 one year later the same children attending first grade were assessed on measures of word and pseudoword reading, text reading fluency, text reading comprehension, and spelling. Complete data from 104 children are available. Hierarchical linear regression and commonality analyses were conducted for each outcome variable. Reading accuracy for both words and pseudowords was predicted not only by phonological awareness, as expected, but also by morphological awareness, suggesting that understanding the functional role of word parts supports the developing phonology–orthography mappings. However, only phonological awareness predicted text reading fluency at this age. Longitudinal prediction of reading comprehension by both receptive vocabulary and morphological awareness was already evident at this age, as expected. Finally, spelling was predicted by preschool phonological awareness, as expected, as well as by morphological awareness, the contribution of which is
Comparative Analysis of Networks of Phonologically Similar Words in English and Spanish
Directory of Open Access Journals (Sweden)
Michael S. Vitevitch
Full Text Available Previous network analyses of several languages revealed a unique set of structural characteristics. One of these characteristics—the presence of many smaller components (referred to as islands—was further examined with a comparative analysis of the island constituents. The results showed that Spanish words in the islands tended to be phonologically and semantically similar to each other, but English words in the islands tended only to be phonologically similar to each other. The results of this analysis yielded hypotheses about language processing that can be tested with psycholinguistic experiments, and offer insight into cross-language differences in processing that have been previously observed.

Full Text Available Children are believed to employ universal processes in simplifying adult language words to match their developing phonology. The present paper is intended to describe the phonological processes used by three Indonesian children aged between 1;8 and 2;6. There is an indication that the utilization of the processes might be not only quantitatively but also qualitatively age-related, and that the processes might actually be of three types: universal (species-specific, local (language-specific, and idiosyncratic (individual-specific.
Phonological Working Memory limitations and Agrammatism: Is there a causal relationship between the two?
Directory of Open Access Journals (Sweden)
Maria Varkanitsa
These results are inconsistent with theories assuming a single WM capacity that deals with all types of linguistic information. Rather, this study provides evidence that syntactic parsing relies on different resources from what is typically measured in verbal WM tasks. The four patients with Broca's aphasia that participated in this study presented with similar phonological WM limitations with only quantitative differences in some tasks, despite the fact that only two of them also had sentence comprehension difficulties. The results also suggest that the agrammatic patients suffer from a specific WM deficit, linked to processing syntactic dependencies, which is not tapped by phonological WM tests.
Monitoring Different Phonological Parameters of Sign Language Engages the Same Cortical Language Network but Distinctive Perceptual Ones.
Cardin, Velia; Orfanidou, Eleni; Kästner, Lena; Rönnberg, Jerker; Woll, Bencie; Capek, Cheryl M; Rudner, Mary
The study of signed languages allows the dissociation of sensorimotor and cognitive neural components of the language signal. Here we investigated the neurocognitive processes underlying the monitoring of two phonological parameters of sign languages: handshape and location. Our goal was to determine if brain regions processing sensorimotor characteristics of different phonological parameters of sign languages were also involved in phonological processing, with their activity being modulated by the linguistic content of manual actions. We conducted an fMRI experiment using manual actions varying in phonological structure and semantics: (1) signs of a familiar sign language (British Sign Language), (2) signs of an unfamiliar sign language (Swedish Sign Language), and (3) invented nonsigns that violate the phonological rules of British Sign Language and Swedish Sign Language or consist of nonoccurring combinations of phonological parameters. Three groups of participants were tested: deaf native signers, deaf nonsigners, and hearing nonsigners. Results show that the linguistic processing of different phonological parameters of sign language is independent of the sensorimotor characteristics of the language signal. Handshape and location were processed by different perceptual and task-related brain networks but recruited the same language areas. The semantic content of the stimuli did not influence this process, but phonological structure did, with nonsigns being associated with longer RTs and stronger activations in an action observation network in all participants and in the supramarginal gyrus exclusively in deaf signers. These results suggest higher processing demands for stimuli that contravene the phonological rules of a signed language, independently of previous knowledge of signed languages. We suggest that the phonological characteristics of a language may arise as a consequence of more efficient neural processing for its perception and production.
Language and short-term memory: the role of perceptual-motor affordance.
Macken, Bill; Taylor, John C; Jones, Dylan M
The advantage for real words over nonwords in serial recall--the lexicality effect--is typically attributed to support for item-level phonology, either via redintegration, whereby partially degraded short-term traces are "cleaned up" via support from long-term representations of the phonological material or via the more robust temporary activation of long-term lexical phonological knowledge that derives from its combination with established lexical and semantic levels of representation. The much smaller effect of lexicality in serial recognition, where the items are re-presented in the recognition cue, is attributed either to the minimal role for redintegration from long-term memory or to the minimal role for item memory itself in such retrieval conditions. We show that the reduced lexicality effect in serial recognition is not a function of the retrieval conditions, but rather because previous demonstrations have used auditory presentation, and we demonstrate a robust lexicality effect for visual serial recognition in a setting where auditory presentation produces no such effect. Furthermore, this effect is abolished under conditions of articulatory suppression. We argue that linguistic knowledge affects the readiness with which verbal material is segmentally recoded via speech motor processes that support rehearsal and therefore affects tasks that involve recoding. On the other hand, auditory perceptual organization affords sequence matching in the absence of such a requirement for segmental recoding and therefore does not show such effects of linguistic knowledge.

Ignition and combustion studies have provided valuable data and guidelines for sodium fire suppression research. The primary necessity is to isolate the oxidant from the fuel, rather than to attempt to cool the sodium below its ignition temperature. Work along these lines has led to the development of smothering tank systems and a dry extinguishing powder. Based on the results obtained, the implementation of these techniques is discussed with regard to sodium fire suppression in the Super-Phenix reactor. (author)

The influence of orthographic experience on the development of phonological preparation in spoken word production.
Li, Chuchu; Wang, Min
Three sets of experiments using the picture naming tasks with the form preparation paradigm investigated the influence of orthographic experience on the development of phonological preparation unit in spoken word production in native Mandarin-speaking children. Participants included kindergarten children who have not received formal literacy instruction, Grade 1 children who are comparatively more exposed to the alphabetic pinyin system and have very limited Chinese character knowledge, Grades 2 and 4 children who have better character knowledge and more exposure to characters, and skilled adult readers who have the most advanced character knowledge and most exposure to characters. Only Grade 1 children showed the form preparation effect in the same initial consonant condition (i.e., when a list of target words shared the initial consonant). Both Grade 4 children and adults showed the preparation effect when the initial syllable (but not tone) among target words was shared. Kindergartners and Grade 2 children only showed the preparation effect when the initial syllable including tonal information was shared. These developmental changes in phonological preparation could be interpreted as a joint function of the modification of phonological representation and attentional shift. Extensive pinyin experience encourages speakers to attend to and select onset phoneme in phonological preparation, whereas extensive character experience encourages speakers to prepare spoken words in syllables.
The Phonological-Distributional Coherence Hypothesis: Cross-Linguistic Evidence in Language Acquisition

Full Text Available OBJECTIVES: This study investigated whether neurophysiologic responses (auditory evoked potentials differ between typically developed children and children with phonological disorders and whether these responses are modified in children with phonological disorders after speech therapy. METHODS: The participants included 24 typically developing children (Control Group, mean age: eight years and ten months and 23 children clinically diagnosed with phonological disorders (Study Group, mean age: eight years and eleven months. Additionally, 12 study group children were enrolled in speech therapy (Study Group 1, and 11 were not enrolled in speech therapy (Study Group 2. The subjects were submitted to the following procedures: conventional audiological, auditory brainstem response, auditory middle-latency response, and P300 assessments. All participants presented with normal hearing thresholds. The study group 1 subjects were reassessed after 12 speech therapy sessions, and the study group 2 subjects were reassessed 3 months after the initial assessment. Electrophysiological results were compared between the groups. RESULTS: Latency differences were observed between the groups (the control and study groups regarding the auditory brainstem response and the P300 tests. Additionally, the P300 responses improved in the study group 1 children after speech therapy. CONCLUSION: The findings suggest that children with phonological disorders have impaired auditory brainstem and cortical region pathways that may benefit from speech therapy.

Is handwriting constrained by phonology? Evidence from Stroop tasks with written responses and Chinese characters
Directory of Open Access Journals (Sweden)
Markus eDamian
Full Text Available To what extent is handwritten word production based on phonological codes? A few studies conducted in Western languages have recently provided evidence showing that phonology contributes to the retrieval of graphemic properties in written output tasks. Less is known about how orthographic production works in languages with non-alphabetic scripts such as written Chinese. We report a Stroop study in which Chinese participants wrote the colour of characters on a digital graphic tablet; characters were either neutral, or homophonic to the target (congruent, or homophonic to an alternative (incongruent. Facilitation was found from congruent homophonic distractors, but only when the homophone shared the same tone with the target. This finding suggests a contribution of phonology to written word production. A second experiment served as a control experiment to exclude the possibility that the effect in Experiment 1 had an exclusively semantic locus. Overall, the findings offer new insight into the relative contribution of phonology to handwriting, particularly in non-Western languages.

The form of a determiner is dependent on different contextual factors: in some languages grammatical number and grammatical gender determine the choice of a determiner variant. In other languages, the phonological onset of the element immediately following the determiner affects selection, too. Previous work has shown that the activation of…
The Role of Phonological versus Morphological Skills in the Development of Arabic Spelling: An Intervention Study.
Taha, Haitham; Saiegh-Haddad, Elinor
The current study investigated the contribution of two linguistic intervention programs, phonological and morphological to the development of word spelling among skilled and poor native Arabic readers, in three grades: second, fourth and sixth. The participants were assigned to three experimental groups: morphological intervention, phonological intervention and a non-intervention control group. Phonological awareness, morphological awareness, and spelling abilities were tested before and after the intervention. Participants from both linguistic intervention programs and in all grades made significant progress in linguistic awareness and spelling after the intervention. The results showed that both intervention programs were successful in promoting children's spelling skills in both groups. Also, older poor readers showed a stronger response to the morphological intervention than the older skilled readers. A transfer effect was found with the phonological training contributing to the morphological skills and vice versa. The results of the current study were discussed in the light of developmental and psycholinguistic views of spelling acquisition as well as the characteristics of Arabic language and orthography.
Phonological Working Memory in German Children with Poor Reading and Spelling Abilities
Steinbrink, Claudia; Klatte, Maria
Deficits in verbal short-term memory have been identified as one factor underlying reading and spelling disorders. However, the nature of this deficit is still unclear. It has been proposed that poor readers make less use of phonological coding, especially if the task can be solved through visual strategies. In the framework of Baddeley's…
Dense Neighborhoods and Mechanisms of Learning: Evidence from Children with Phonological Delay
Gierut, Judith A.; Morrisette, Michele L.
There is a noted advantage of dense neighborhoods in language acquisition, but the learning mechanism that drives the effect is not well understood. Two hypotheses--long-term auditory word priming and phonological working memory--have been advanced in the literature as viable accounts. These were evaluated in two treatment studies enrolling twelve…

Word Structures of Granada Spanish-Speaking Preschoolers with Typical versus Protracted Phonological Development
May Bernhardt, B.; Hanson, R.; Perez, D.; Ávila, C.; Lleó, C.; Stemberger, J. P.; Carballo, G.; Mendoza, E.; Fresneda, D.; Chávez-Peón, M.
Background: Research on children's word structure development is limited. Yet, phonological intervention aims to accelerate the acquisition of both speech-sounds and word structure, such as word length, stress or shapes in CV sequences. Until normative studies and meta-analyses provide in-depth information on this topic, smaller investigations can…

The Effect of Sonority on Word Segmentation: Evidence for the Use of a Phonological Universal
Ettlinger, Marc; Finn, Amy S.; Hudson Kam, Carla L.
It has been well documented how language-specific cues may be used for word segmentation. Here, we investigate what role a language-independent phonological universal, the sonority sequencing principle (SSP), may also play. Participants were presented with an unsegmented speech stream with non-English word onsets that juxtaposed adherence to the…
The Influence of the Phonological Neighborhood Clustering Coefficient on Spoken Word Recognition
Chan, Kit Ying; Vitevitch, Michael S.
Clustering coefficient--a measure derived from the new science of networks--refers to the proportion of phonological neighbors of a target word that are also neighbors of each other. Consider the words "bat", "hat", and "can", all of which are neighbors of the word "cat"; the words "bat" and…
The relation between musical abilities and the phonological awareness in pre-school children
Directory of Open Access Journals (Sweden)
Anja Božič
Full Text Available The pre-school period plays a very important role in the language development. One of the significant indicators of this development is the phonological awareness. Some of the previous studies reported the presence of the relation between the phonological awareness and musical abilities. Our main goal was to examine this relation with the Test of the phonological awareness and the Test of musical abilities on 67 Slovene preschool children, aged from 5 to 6. We also wanted to investigate the differences between boys (N = 36 and girls (N = 31 and the differences between two age groups (aged from 5 to 5.5 years, N = 32, and from 5.5 to 6 years, N = 35. The results confirmed the connection between musical abilities and the phonological awareness. They also indicated that the recognition of the first and the last phoneme is related to melodic awareness and that phoneme merging is mainly related to rhythm awareness. No significant differences were found between male and female children or between the groups of the children of different ages.
A programme for bidirectional phonology and phonetics and their acquisition and evolution
Boersma, P.; Benz, A.; Mattausch, J.
This paper summarizes an existing bidirectional six-level model of phonology and phonetics (and a bit of morphology). Bidirectionality in this case refers to the modelling of both the speaking process (production) and the listening process (comprehension). The elements of the grammar (the
Clinical Comparisons: Phonological Processes and Their Relationship to Traditional Phoneme Acquisition Norms.
Culbertson, William R.; Tanner, Dennis C.
This article compares and contrasts the two major psycholinguistic philosophies of speech development, the traditional and the phonological approaches. The traditional approach is seen as most useful for children whose speech is only mildly impaired or who need oral sensorimotor stimulation. For severely unintelligible speech, the phonological…

Functional Deficits in Phonological Working Memory in Children with Intellectual Disabilities
Schuchardt, Kirsten; Maehler, Claudia; Hasselhorn, Marcus
Recent studies indicate that children with intellectual disabilities have functional limitations primarily in the phonological loop of working memory (Baddeley, 1986). These findings are indicative of a specific structural deficit. Building on this research, the present study examines whether it is possible to identify specific phonological…
Deaf Children's Use of Phonological Coding: Evidence from Reading, Spelling, and Working Memory
Harris, Margaret; Moreno, Constanza
Two groups of deaf children, aged 8 and 14 years, were presented with a number of tasks designed to assess their reliance on phonological coding. Their performance was compared with that of hearing children of the same chronological age (CA) and reading age (RA).

Modeling the length effect: Specifying the relation with visual and phonological correlates of reading
van den Boer, M.; de Jong, P.F.; Haentjens-van Meeteren, M.M.
Beginning readers' reading latencies increase as words become longer. This length effect is believed to be a marker of a serial reading process. We examined the effects of visual and phonological skills on the length effect. Participants were 184 second-grade children who read 3- to 5-letter words
Phonological fluency strategy of switching differentiates relapsing-remitting and secondary progressive multiple sclerosis patients.
Messinis, L; Kosmidis, M H; Vlahou, C; Malegiannaki, A C; Gatzounis, G; Dimisianos, N; Karra, A; Kiosseoglou, G; Gourzis, P; Papathanasopoulos, P
The strategies used to perform a verbal fluency task appear to be reflective of cognitive abilities necessary for successful daily functioning. In the present study, we explored potential differences in verbal fluency strategies (switching and clustering) used to maximize word production by patients with relapsing-remitting multiple sclerosis (RRMS) versus patients with secondary progressive multiple sclerosis (SPMS). We further assessed impairment rates and potential differences in the sensitivity and specificity of phonological versus semantic verbal fluency tasks in discriminating between those with a diagnosis of MS and healthy adults. We found that the overall rate of impaired verbal fluency in our MS sample was consistent with that in other studies. However, we found no differences between types of MS (SPMS, RRMS), on semantic or phonological fluency word production, or the strategies used to maximize semantic fluency. In contrast, we found that the number of switches differed significantly in the phonological fluency task between the SPMS and RRMS subtypes. The clinical utility of semantic versus phonological fluency in discriminating MS patients from healthy controls did not indicate any significant differences. Further, the strategies used to maximize performance did not differentiate MS subgroups or MS patients from healthy controls.
Does Kaniso activate CASINO?: input coding schemes and phonology in visual-word recognition.
Acha, Joana; Perea, Manuel
Most recent input coding schemes in visual-word recognition assume that letter position coding is orthographic rather than phonological in nature (e.g., SOLAR, open-bigram, SERIOL, and overlap). This assumption has been drawn - in part - by the fact that the transposed-letter effect (e.g., caniso activates CASINO) seems to be (mostly) insensitive to phonological manipulations (e.g., Perea & Carreiras, 2006, 2008; Perea & Pérez, 2009). However, one could argue that the lack of a phonological effect in prior research was due to the fact that the manipulation always occurred in internal letter positions - note that phonological effects tend to be stronger for the initial syllable (Carreiras, Ferrand, Grainger, & Perea, 2005). To reexamine this issue, we conducted a masked priming lexical decision experiment in which we compared the priming effect for transposed-letter pairs (e.g., caniso-CASINO vs. caviro-CASINO) and for pseudohomophone transposed-letter pairs (kaniso-CASINO vs. kaviro-CASINO). Results showed a transposed-letter priming effect for the correctly spelled pairs, but not for the pseudohomophone pairs. This is consistent with the view that letter position coding is (primarily) orthographic in nature.
Do maternal interaction and early language predict phonological awareness in 3- to 4-year-olds?
Silvén, M.; Niemi, P.; Voeten, M.J.M.
The present study reports longitudinal data on how phonological awareness is affected by mother-child interaction and the child's language development. Sixty-six Finnish children were videotaped at 12 and 24 months of age with their mother, during joint play episodes, to assess maternal sensitivity

Multisensory Spatial Attention Deficits Are Predictive of Phonological Decoding Skills in Developmental Dyslexia
Facoetti, Andrea; Trussardi, Anna Noemi; Ruffino, Milena; Lorusso, Maria Luisa; Cattaneo, Carmen; Galli, Raffaella; Molteni, Massimo; Zorzi, Marco
Although the dominant approach posits that developmental dyslexia arises from deficits in systems that are exclusively linguistic in nature (i.e., phonological deficit theory), dyslexics show a variety of lower level deficits in sensory and attentional processing. Although their link to the reading disorder remains contentious, recent empirical…
Understanding the Contributions of Prosodic Phonology to Morphological Development: Implications for Children with Specific Language Impairment
Demuth, Katherine; Tomas, Ekaterina
A growing body of research with typically developing children has begun to show that the acquisition of grammatical morphemes interacts not only with a developing knowledge of syntax, but also with developing abilities at the interface with prosodic phonology. In particular, a Prosodic Licensing approach to these issues provides a framework for…
Strong and long: effects of word length on phonological binding in verbal short-term memory.
Jefferies, Elizabeth; Frankish, Clive; Noble, Katie
This study examined the effects of item length on the contribution of linguistic knowledge to immediate serial recall (ISR). Long words are typically recalled more poorly than short words, reflecting the greater demands that they place on phonological encoding, rehearsal, and production. However, reverse word length effects--that is, better recall of long than short words--can also occur in situations in which phonological maintenance is difficult, suggesting that long words derive greater support from long-term lexical knowledge. In this study, long and short words and nonwords (containing one vs. three syllables) were presented for immediate serial recall in (a) pure lists and (b) unpredictable mixed lists of words and nonwords. The mixed-list paradigm is known to disrupt the phonological stability of words, encouraging their phonemes to recombine with the elements of other list items. In this situation, standard length effects were seen for nonwords, while length effects for words were absent or reversed. A detailed error analysis revealed that long words were more robust to the mixed-list manipulation than short words: Their phonemes were less likely to be omitted and to recombine with phonemes from other list items. These findings support an interactive view of short-term memory, in which long words derive greater benefits from lexical knowledge than short words-especially when their phonological integrity is challenged by the inclusion of nonwords in mixed lists.
Phonological Short-Term Memory, Working Memory and Foreign Language Performance in Intensive Language Learning

Kindergarten Prevention of Dyslexia: Does Training in Phonological Awareness Work for Everybody?
Schneider, Wolfgang; Ennemoser, Marco; Roth, Ellen; Kuspert, Petra
A study examined effects of phonological awareness training on 191 German kindergartners. Comparisons of children at risk with average and advanced children revealed that training gains were similar for all of these groups. Furthermore, training had comparable long-term effects on reading and spelling in grades 1 and 2 for each group. (Author/CR)
Effects of Rhyme and Spelling Patterns on Auditory Word ERPs Depend on Selective Attention to Phonology
Yoncheva, Yuliya N.; Maurer, Urs; Zevin, Jason D.; McCandliss, Bruce D.
ERP responses to spoken words are sensitive to both rhyming effects and effects of associated spelling patterns. Are such effects automatically elicited by spoken words or dependent on selectively attending to phonology? To address this question, ERP responses to spoken word pairs were investigated under two equally demanding listening tasks that…
Interfering with free recall of words: Detrimental effects of phonological competition.
Fernandes, Myra A; Wammes, Jeffrey D; Priselac, Sandra; Moscovitch, Morris
We examined the effect of different distracting tasks, performed concurrently during memory retrieval, on recall of a list of words. By manipulating the type of material and processing (semantic, orthographic, and phonological) required in the distracting task, and comparing the magnitude of memory interference produced, we aimed to infer the kind of representation upon which retrieval of words depends. In Experiment 1, identifying odd digits concurrently during free recall disrupted memory, relative to a full attention condition, when the numbers were presented orthographically (e.g. nineteen), but not numerically (e.g. 19). In Experiment 2, a distracting task that required phonological-based decisions to either word or picture material produced large, but equivalent effects on recall of words. In Experiment 3, phonological-based decisions to pictures in a distracting task disrupted recall more than when the same pictures required semantically-based size estimations. In Experiment 4, a distracting task that required syllable decisions to line drawings interfered significantly with recall, while an equally difficult semantically-based color-decision task about the same line drawings, did not. Together, these experiments demonstrate that the degree of memory interference experienced during recall of words depends primarily on whether the distracting task competes for phonological representations or processes, and less on competition for semantic or orthographic or material-specific representations or processes.

Neural correlates reveal sub-lexical orthography and phonology during reading aloud: A review
Directory of Open Access Journals (Sweden)
Kalinka eTimmer
Full Text Available The sub-lexical conversion of graphemes-to-phonemes (GPC during reading has been investigated extensively with behavioral measures, as well as event-related potentials (ERPs. Most research utilizes silent reading (e.g., lexical decision task for which phonological activation is not a necessity. However, recent research employed reading aloud to capture sub-lexical GPC. The masked priming paradigm avoids strategic processing and is therefore well suitable for capturing sub-lexical processing instead of lexical effects. By employing ERPs, the on-line time course of sub-lexical GPC can be observed before the overt response. ERPs have revealed that besides phonological activation, as revealed by behavioral studies, there is also early orthographic activation. This review describes studies in one's native language, in one's second language, and in a cross-language situation. We discuss the implications the ERP results have on different (computational models. First, the ERP results show that computational models should assume an early locus of the grapheme-to-phoneme-conversion (GPC. Second, cross-language studies reveal that the phonological representations from both languages of a bilingual become activated automatically and the phonology belonging to the context is selected rapidly. Therefore, it is important to extend the scope of computational models of reading (aloud to multiple lexicons.

[Investigating phonological planning processes in speech production through a speech-error induction technique].
Nakayama, Masataka; Saito, Satoru
The present study investigated principles of phonological planning, a common serial ordering mechanism for speech production and phonological short-term memory. Nakayama and Saito (2014) have investigated the principles by using a speech-error induction technique, in which participants were exposed to an auditory distracIor word immediately before an utterance of a target word. They demonstrated within-word adjacent mora exchanges and serial position effects on error rates. These findings support, respectively, the temporal distance and the edge principles at a within-word level. As this previous study induced errors using word distractors created by exchanging adjacent morae in the target words, it is possible that the speech errors are expressions of lexical intrusions reflecting interactive activation of phonological and lexical/semantic representations. To eliminate this possibility, the present study used nonword distractors that had no lexical or semantic representations. This approach successfully replicated the error patterns identified in the abovementioned study, further confirming that the temporal distance and edge principles are organizing precepts in phonological planning.

Can infants learn phonology in the lab? A meta-analytic answer.
Cristia, Alejandrina
Two of the key tasks facing the language-learning infant lie at the level of phonology: establishing which sounds are contrastive in the native inventory, and determining what their possible syllabic positions and permissible combinations (phonotactics) are. In 2002-2003, two theoretical proposals, one bearing on how infants can learn sounds (Maye, Werker, & Gerken, 2002) and the other on phonotactics (Chambers, Onishi, & Fisher, 2003), were put forward on the pages of Cognition, each supported by two laboratory experiments, wherein a group of infants was briefly exposed to a set of pseudo-words, and plausible phonological generalizations were tested subsequently. These two papers have received considerable attention from the general scientific community, and inspired a flurry of follow-up work. In the context of questions regarding the replicability of psychological science, the present work uses a meta-analytic approach to appraise extant empirical evidence for infant phonological learning in the laboratory. It is found that neither seminal finding (on learning sounds and learning phonotactics) holds up when close methodological replications are integrated, although less close methodological replications do provide some evidence in favor of the sound learning strand of work. Implications for authors and readers of this literature are drawn out. It would be desirable that additional mechanisms for phonological learning be explored, and that future infant laboratory work employ paradigms that rely on constrained and unambiguous links between experimental exposure and measured infant behavior.

Verbal working memory is related to the acquisition of cross-linguistic phonological regularities
Bosma, E.; Heeringa, W.; Hoekstra, E.; Versloot, A.; Blom, E.
Closely related languages share cross-linguistic phonological regularities, such as Frisian -âld [c:t] and Dutch -oud [hut], as in the cognate pairs kâld [kc:t] - koud [khut] 'cold' and wâld [wc:t] - woud [whut] 'forest'. Within Bybee's (1995, 2001, 2008, 2010) network model, these regularities are,
Patterns of cerebral activation during lexical and phonological reading in Portuguese
Directory of Open Access Journals (Sweden)
Senaha M.L.H.
Full Text Available According to the concepts of cognitive neuropsychology, there are two principal routes of reading processing: a lexical route, in which global reading of words occurs and a phonological route, responsible for the conversion of the graphemes into their respective phonemes. In the present study, functional magnetic resonance imaging (fMRI was used to investigate the patterns of cerebral activation in lexical and phonological reading by 13 healthy women with a formal educational level greater than 11 years. Participants were submitted to a silent reading task containing three types of stimuli: real words (irregular and foreign words, nonwords and illegitimate graphic stimuli. An increased number of activated voxels were identified by fMRI in the word reading (lexical processing than in the nonword reading (phonological processing task. In word reading, activation was greater than for nonwords in the following areas: superior, middle and inferior frontal gyri, and bilateral superior temporal gyrus, right cerebellum and the left precentral gyrus, as indicated by fMRI. In the reading of nonwords, the activation was predominant in the right cerebellum and in the left superior temporal gyrus. The results of the present study suggest the existence of differences in the patterns of cerebral activation during lexical and phonological reading, with greater involvement of the right hemisphere in reading words than nonwords.
The influence of visual and phonological features on the hemispheric processing of hierarchical Navon letters.
Aiello, Marilena; Merola, Sheila; Lasaponara, Stefano; Pinto, Mario; Tomaiuolo, Francesco; Doricchi, Fabrizio
The possibility of allocating attentional resources to the "global" shape or to the "local" details of pictorial stimuli helps visual processing. Investigations with hierarchical Navon letters, that are large "global" letters made up of small "local" ones, consistently demonstrate a right hemisphere advantage for global processing and a left hemisphere advantage for local processing. Here we investigated how the visual and phonological features of the global and local components of Navon letters influence these hemispheric advantages. In a first study in healthy participants, we contrasted the hemispheric processing of hierarchical letters with global and local items competing for response selection, to the processing of hierarchical letters in which a letter, a false-letter conveying no phonological information or a geometrical shape presented at the unattended level did not compete for response selection. In a second study, we investigated the hemispheric processing of hierarchical stimuli in which global and local letters were both visually and phonologically congruent (e.g. large uppercase G made of smaller uppercase G), visually incongruent and phonologically congruent (e.g. large uppercase G made of small lowercase g) or visually incongruent and phonologically incongruent (e.g. large uppercase G made of small lowercase or uppercase M). In a third study, we administered the same tasks to a right brain damaged patient with a lesion involving pre-striate areas engaged by global processing. The results of the first two experiments showed that the global abilities of the left hemisphere are limited because of its strong susceptibility to interference from local letters even when these are irrelevant to the task. Phonological features played a crucial role in this interference because the interference was entirely maintained also when letters at the global and local level were presented in different uppercase vs. lowercase formats. In contrast, when local features
Improving Phonological Awareness in Parents of Children at Risk of Literacy Difficulties: A Preliminary Evaluation of the Boost Program
Directory of Open Access Journals (Sweden)
Mark E. Boyes
Full Text Available BackgroundPhonological awareness is an important skill underpinning the development of early literacy. Given the central role of parents in supporting the development of children's early literacy skills, and that poor parental phonological awareness is associated with poorer child literacy outcomes, it is possible that improving parent phonological awareness may aid literacy development for at-risk children. This study is a preliminary evaluation of a program aiming to improve phonological awareness skills of parents in low socioeconomic status communities, and also provide these parents with strategies to support their child's literacy development.MethodsAfter completing the program, participants were asked if it had helped them learn about how to assist their child's reading and spelling, whether they planned on using the resources provided, and if they would be likely to attend a future workshop building on the Boost program. Phonological awareness measures (rhyme, syllable, and phoneme level, and measures of overall confidence in performance on the phonological awareness tasks, were administered both before and after attending the program.ResultsAlmost all parents indicated that the program helped with learning how to assist their child's reading and spelling, that they would use the resources provided, and would likely attend a future workshop. Significant increases in pre- to post-program phonological awareness scores were obtained at the rhyme and phoneme level.ConclusionThe program and associated resources appear acceptable to parents in communities with high rates of literacy problems and improved parents' phonological awareness skills. However, findings are preliminary and further evaluation using more rigorous methodologies and testing whether improvements in parents' phonological awareness translate into better literacy outcomes for children is needed.

Closely related languages share cross-linguistic phonological regularities, such as Frisian -âld [ͻ:t] and Dutch -oud [ʱut], as in the cognate pairs kâld [kͻ:t] - koud [kʱut] 'cold' and wâld [wͻ:t] - woud [wʱut] 'forest'. Within Bybee's (1995, 2001, 2008, 2010) network model, these regularities are, just like grammatical rules within a language, generalizations that emerge from schemas of phonologically and semantically related words. Previous research has shown that verbal working memory is related to the acquisition of grammar, but not vocabulary. This suggests that verbal working memory supports the acquisition of linguistic regularities. In order to test this hypothesis we investigated whether verbal working memory is also related to the acquisition of cross-linguistic phonological regularities. For three consecutive years, 5- to 8-year-old Frisian-Dutch bilingual children ( n = 120) were tested annually on verbal working memory and a Frisian receptive vocabulary task that comprised four cognate categories: (1) identical cognates, (2) non-identical cognates that either do or (3) do not exhibit a phonological regularity between Frisian and Dutch, and (4) non-cognates. The results showed that verbal working memory had a significantly stronger effect on cognate category (2) than on the other three cognate categories. This suggests that verbal working memory is related to the acquisition of cross-linguistic phonological regularities. More generally, it confirms the hypothesis that verbal working memory plays a role in the acquisition of linguistic regularities.

Full Text Available The aim of this study was to examine the phonological errors made by dyslexics and non-dyslexic children in Persian orthography which is transcribed with two distinct spelling: words spelled with long vowels (transparent and words spelled with short vowels (diacritics are called opaque words. The sample of the study consisted of Fifteen dyslexic students with the mean age of 9.6, (SD= 1.5 and fifteen unimpaired elementary students with the mean age of 9.6 (SD= 1.4 who were Persian residents of 6th district of Tehran. All the participants were controlled for IQ, social class and behavioral disorders. The instrument used in this research was a set of phonological awareness task (rhymed word detection, rhymed word production, first sound detection, final sound detection, blending syllables and syllable deletion. Participants were required to do each of these phonological awareness tasks in order to compare their error rates in transparent and opaque words. The performance of the two groups was examined according to the effect of transparency variable. Data analysis was done using SPSS software. Overall, the finding showed that dyslexic children encountered more problems in both transparent and opaque words than did unimpaired children and the difference was statistically significant (P<0/05. On the other hand, correlation analysis (Pearson showed a significant negative interaction between two variables (transparency and subjects (P< 0/001. This means that dyslexic children in compare to normal ones committed more errors in phonological awareness tasks. The results of this research show that the degree of the transparency of writing systems affects the phonological processing ability of individuals.
The contribution of phonological knowledge, memory, and language background to reading comprehension in deaf populations

Full Text Available While reading is challenging for many deaf individuals, some become proficient readers. Yet we do not know the component processes that support reading comprehension in these individuals. Speech-based phonological knowledge is one of the strongest predictors of reading comprehension in hearing individuals, yet its role in deaf readers is controversial. This could reflect the highly varied language backgrounds among deaf readers as well as the difficulty of disentangling the relative contribution of phonological versus orthographic knowledge of spoken language, in our case 'English', in this population. Here we assessed the impact of language experience on reading comprehension in deaf readers by recruiting oral deaf individuals, who use spoken English as their primary mode of communication, and deaf native signers of American Sign Language. First, to address the contribution of spoken English phonological knowledge in deaf readers, we present novel tasks that evaluate phonological versus orthographic knowledge. Second, the impact of this knowledge, as well as verbal short-term memory and long-term memory skills, on reading comprehension was evaluated. The best predictor of reading comprehension differed as a function of language experience, with long-term memory, as measured by free recall, being a better predictor in deaf native signers than in oral deaf. In contrast, the measures of English phonological knowledge, independent of orthographic knowledge, best predicted reading comprehension in oral deaf individuals. These results suggest successful reading strategies differ across deaf readers as a function of their language experience, and highlight a possible alternative route to literacy in deaf native signers.
Phonological awareness and short-term memory in hearing and deaf individuals of different communication backgrounds.
Koo, Daniel; Crain, Kelly; LaSasso, Carol; Eden, Guinevere F
Previous work in deaf populations on phonological coding and working memory, two skills thought to play an important role in the acquisition of written language skills, have focused primarily on signers or did not clearly identify the subjects' native language and communication mode. In the present study, we examined the effect of sensory experience, early language experience, and communication mode on the phonological awareness skills and serial recall of linguistic items in deaf and hearing individuals of different communicative and linguistic backgrounds: hearing nonsigning controls, hearing users of ASL, deaf users of ASL, deaf oral users of English, and deaf users of cued speech. Since many current measures of phonological awareness skills are inappropriate for deaf populations on account of the verbal demands in the stimuli or response, we devised a nonverbal phonological measure that addresses this limitation. The Phoneme Detection Test revealed that deaf cuers and oral users, but not deaf signers, performed as well as their hearing peers when detecting phonemes not transparent in the orthography. The second focus of the study examined short-term memory skills and found that in response to the traditional digit span as well as an experimental visual version, digit-span performance was similar across the three deaf groups, yet deaf subjects' retrieval was lower than that of hearing subjects. Our results support the claim (Bavelier et al., 2006) that lexical items processed in the visual-spatial modality are not as well retained as information processed in the auditory channel. Together these findings show that the relationship between working memory, phonological coding, and reading may not be as tightly interwoven in deaf students as would have been predicted from work conducted in hearing students.
Thyroxin hormone suppression treatment
International Nuclear Information System (INIS)
Samuel, A.M.
One of the important modalities of treatment of thyroid cancer (TC) after surgery is the administration of thyroxin as an adjuvant treatment. The analysis supports the theory that thyroid suppression plays an important role in patient management. 300 μg of thyroxin, as this is an adequate dose for suppression is given. Ideally the dose should be tailored by testing s-TSH levels. However, since a large number of the patients come from out station cities and villages this is impractical. We therefore depend on clinical criteria of hyperthyroid symptoms and adjust the dose. Very few patients need such adjustment
Contrasting contributions of phonological short-term memory and long-term knowledge to vocabulary learning in a foreign language.
Masoura, Elvira V; Gathercole, Susan E
The contributions of phonological short-term memory and existing foreign vocabulary knowledge to the learning of new words in a second language were compared in a sample of 40 Greek children studying English at school. The children's speed of learning new English words in a paired-associate learning task was strongly influenced by their current English vocabulary, but was independent of phonological memory skill, indexed by nonword repetition ability. However, phonological memory performance was closely linked to English vocabulary scores. The findings suggest that in learners with considerable familiarity with a second language, foreign vocabulary acquisition is mediated largely by use of existing knowledge representations.

Purpose: To prevent the pressure in the reactor container from excessively increasing even when vapor leaks from the dry well to a space of the suppression chamber, without passing though the suppression pool at the time of loss of coolant accident. Constitution: When vapor of a high temperature and a high pressure at the time of loss of coolant accident flows from the dry well to the suppression chamber without passing through suppression pool water, vapor dose not condense with pool water, and therefore the pressure within the chamber abnormally increases. For this reason, this abnormal pressure is detected by a pressure detector thereby to start the operations of a blower and a pump. By starting the blower, the pressure in the dry well becomes lower than the pressure in the chamber, and vapor entirely passes through the pool water and entirely condenses with the pool water. By starting the pump, the pool water is sprayed over the space of the chamber, and vapor in the space is condensed. (Yoshino, Y.)
Age of Bilingual Exposure Is Related to the Contribution of Phonological and Semantic Knowledge to Successful Reading Development.
Jasińska, Kaja K; Petitto, Laura-Ann
Bilingual children's reading as a function of age of first bilingual language exposure (AoE) was examined. Bilingual (varied AoE) and monolingual children (N = 421) were compared in their English language and reading abilities (6-10 years) using phonological awareness, semantic knowledge, and reading tasks. Structural equation modeling was applied to determine how bilingual AoE predicts reading outcomes. Early exposed bilinguals outperformed monolinguals on phonological awareness and word reading. Phonology and semantic (vocabulary) knowledge differentially predicted reading depending on the bilingual experience and AoE. Understanding how bilingual experiences impact phonological awareness and semantic knowledge, and in turn, impact reading outcomes is relevant for our understanding of what language and reading skills are best to focus on, and when, to promote optimal reading success. © 2017 The Authors.

Phonological processes in the speech of school-age children with hearing loss: Comparisons with children with normal hearing.
Asad, Areej Nimer; Purdy, Suzanne C; Ballard, Elaine; Fairgray, Liz; Bowen, Caroline
In this descriptive study, phonological processes were examined in the speech of children aged 5;0-7;6 (years; months) with mild to profound hearing loss using hearing aids (HAs) and cochlear implants (CIs), in comparison to their peers. A second aim was to compare phonological processes of HA and CI users. Children with hearing loss (CWHL, N = 25) were compared to children with normal hearing (CWNH, N = 30) with similar age, gender, linguistic, and socioeconomic backgrounds. Speech samples obtained from a list of 88 words, derived from three standardized speech tests, were analyzed using the CASALA (Computer Aided Speech and Language Analysis) program to evaluate participants' phonological systems, based on lax (a process appeared at least twice in the speech of at least two children) and strict (a process appeared at least five times in the speech of at least two children) counting criteria. Developmental phonological processes were eliminated in the speech of younger and older CWNH while eleven developmental phonological processes persisted in the speech of both age groups of CWHL. CWHL showed a similar trend of age of elimination to CWNH, but at a slower rate. Children with HAs and CIs produced similar phonological processes. Final consonant deletion, weak syllable deletion, backing, and glottal replacement were present in the speech of HA users, affecting their overall speech intelligibility. Developmental and non-developmental phonological processes persist in the speech of children with mild to profound hearing loss compared to their peers with typical hearing. The findings indicate that it is important for clinicians to consider phonological assessment in pre-school CWHL and the use of evidence-based speech therapy in order to reduce non-developmental and non-age-appropriate developmental processes, thereby enhancing their speech intelligibility.

Laterality of Temporoparietal Causal Connectivity during the Prestimulus Period Correlates with Phonological Decoding Task Performance in Dyslexic and Typical Readers
Frye, Richard E.; Liederman, Jacqueline; McGraw Fisher, Janet; Wu, Meng-Hung
We examined how effective connectivity into and out of the left and right temporoparietal areas (TPAs) to/from other key cortical areas affected phonological decoding in 7 dyslexic readers (DRs) and 10 typical readers (TRs) who were young adults. Granger causality was used to compute the effective connectivity of the preparatory network 500 ms prior to presentation of nonwords that required phonological decoding. Neuromagnetic activity was analyzed within the low, medium, and high beta and ga...
The Contribution of Numerical Magnitude Comparison and Phonological Processing to Individual Differences in Fourth Graders' Multiplication Fact Ability.
Directory of Open Access Journals (Sweden)
Tamara M J Schleepen
Full Text Available Although numerical magnitude processing has been related to individual differences in arithmetic, its role in children's multiplication performance remains largely unknown. On the other hand, studies have indicated that phonological awareness is an important correlate of individual differences in children's multiplication performance, but the involvement of phonological memory, another important phonological processing skill, has not been studied in much detail. Furthermore, knowledge about the relative contribution of above mentioned processes to the specific arithmetic operation of multiplication in children is lacking. The present study therefore investigated for the first time the unique contributions of numerical magnitude comparison and phonological processing in explaining individual differences in 63 fourth graders' multiplication fact ability (mean age = 9.6 years, SD = .67. The results showed that children's multiplication fact competency correlated significantly with symbolic and nonsymbolic magnitude comparison as well as with phonological short-term memory. A hierarchical regression analysis revealed that, after controlling for intellectual ability and general reaction time, both symbolic and nonsymbolic magnitude comparison and phonological short-term memory accounted for unique variance in multiplication fact performance. The ability to compare symbolic magnitudes was found to contribute the most, indicating that the access to numerical magnitudes by means of Arabic digits is a key factor in explaining individual differences in children's multiplication fact ability.
Physiologic discrimination of stop consonants relates to phonological skills in pre-readers: A biomarker for subsequent reading ability?
Directory of Open Access Journals (Sweden)
Travis eWhite-Schwoch
Full Text Available Reading development builds upon the accurate representation of the phonological structure of spoken language. This representation and its neural foundations have been studied extensively with respect to reading due to pervasive performance deficits on basic phonological tasks observed in children with dyslexia. The subcortical auditory system—a site of intersection for sensory and cognitive input—is exquisitely tuned to code fine timing differences between phonemes, and so likely plays a foundational role in the development of phonological processing and, eventually, reading. This temporal coding of speech varies systematically with reading ability in school age children. Little is known, however, about subcortical speech representation in pre-school age children. We measured auditory brainstem responses to the stop consonants [ba] and [ga] in a cohort of 4-year-old children and assessed their phonological skills. In a typical auditory system, brainstem responses to [ba] and [ga] are out of phase (i.e., differ in time due to formant frequency differences in the consonant-vowel transitions of the stimuli. We found that children who performed worst on the phonological awareness task insufficiently code this difference, revealing a physiologic link between early phonological skills and the neural representation of speech. We discuss this finding in light of existing theories of the role of the auditory system in developmental dyslexia, and argue for a systems-level perspective for understanding the importance of precise temporal coding for learning to read.
Effect of phonological and morphological awareness on reading comprehension in Hebrew-speaking adolescents with reading disabilities.
Schiff, Rachel; Schwartz-Nahshon, Sarit; Nagar, Revital
This research explored phonological and morphological awareness among Hebrew-speaking adolescents with reading disabilities (RD) and its effect on reading comprehension beyond phonological and word-reading abilities. Participants included 39 seventh graders with RD and two matched control groups of normal readers: 40 seventh graders matched for chronological age (CA) and 38 third graders matched for reading age (RA). We assessed phonological awareness, word reading, morphological awareness, and reading comprehension. Findings indicated that the RD group performed similarly to the RA group on phonological awareness but lower on phonological decoding. On the decontextualized morphological task, RD functioned on par with RA, whereas in a contextualized task RD performed above RA but lower than CA. In reading comprehension, RD performed as well as RA. Finally, results indicated that for normal readers contextual morphological awareness uniquely contributed to reading comprehension beyond phonological and word-reading abilities, whereas no such unique contribution emerged for the RD group. The absence of an effect of morphological awareness in predicting reading comprehension was suggested to be related to a different recognition process employed by RD readers which hinder the ability of these readers to use morphosemantic structures. The lexical quality hypothesis was proposed as further support to the findings, suggesting that a low quality of lexical representation in RD students leads to ineffective reading skills and comprehension. Lexical representation is thus critical for both lexical as well as comprehension abilities.

The cross section for J/Ψ production in Pb-Pb interactions at 158 GeV per nucleon is measured at the CERN SPS by the NA50 experiment. The final results from the 1995 run are presented here together with preliminary ones from the high-statistics 1996 run. An anomalous J/Ψ suppression is observed in Pb-Pb collisions as compared to extrapolations of the previous results obtained by the NA38 experiment with proton and lighter ion beams. The results of the two runs are in good agreement. The results from the 1996 run allow the study of the onset of the anomalous suppression within the same set of data, showing evidence of a sharp change of behaviour around a value of neutral transverse energy, as measured by our electromagnetic calorimeter, of about 50 GeV
Consequences of phonological ability for intelligibility of speech in youngsters with cleft palate
DEFF Research Database (Denmark)
Willadsen, Elisabeth; Poulsen, Mads
In a previous Randomized Clinical Trial (RCT) including children with unilateral cleft lip and palate, it was found that children who had the entire palate closed by 12 months of age had almost as good phonological abilities as a control group, whereas a group of children with a residual cleft...... groups. Based on a pilot study a difference between the groups was observed, suggesting that control children were most easily understood, followed by children with closed palates who were more easily understood than children with a residual cleft....... in the hard palate performed significantly worse at 3 years of age (Willadsen, in press). To investigate the influence of phonological ability on intelligibility of speech in 14 children from each of the 3 groups, an investigation including 84 lay listeners was conducted. The lay listeners were presented...
A markedness analysis of initial consonant clusters in Aphasic Phonological Impairment: A case study
Directory of Open Access Journals (Sweden)
Lesley Wolk
Full Text Available The purpose of this study was to assess both the theoretical and clinical value of markedness theory in phonological impairment in aphasia. A markedness analysis was carried out on initial consonant clusters in a single aphasic adult, at two points during the spontaneous recovery phase. Results revealed systematic, rule-governed behaviour, reflecting similar linguistic trends, in terms of natural segments and natural processes, on both testing occasions. Some inadequacies of the distinctive feature approach are discussed. The findings of this study suggest that a markedness analysis may be extremely useful for the analysis and treatment of phonological disorders in aphasia.
Using sound to solve syntactic problems: the role of phonology in grammatical category assignments.
Kelly, M H
One ubiquitous problem in language processing involves the assignment of words to the correct grammatical category, such as noun or verb. In general, semantic and syntactic cues have been cited as the principal information for grammatical category assignment, to the neglect of possible phonological cues. This neglect is unwarranted, and the following claims are made: (a) Numerous correlations between phonology and grammatical class exist, (b) some of these correlations are large and can pervade the entire lexicon of a language and hence can involve thousands of words, (c) experiments have repeatedly found that adults and children have learned these correlations, and (d) explanations for how these correlations arose can be proposed and evaluated. Implications of these phenomena for language representation and processing are discussed.
Effects of phonological awareness and naming speed on mathematics skills in children with mild intellectual disabilities.
Foster, Matthew E; Sevcik, Rose A; Romski, Maryann; Morris, Robin D
Both phonological awareness (PA) and naming speed have been identified as two skills related to the development of mathematics skills for children with and without learning disabilities. The purpose of the present study was to investigate the relationships between PA and colour naming speed for 265 elementary school students with mild intellectual disabilities (MID). Participants were assessed using the Comprehensive Test of Phonological Processes and the KeyMath Revised Diagnostic Inventory of Essential Mathematics. Hierarchical regression analyses accounting for the effects of age indicated that children with MID rely on both PA and naming speed when solving mathematics problems, although PA was the more robust indicator of the two. As a whole, these results suggest that children with intellectual disabilities evidence the same types of reading and math relationships as shown for other populations of children.
The (null impact of pseudohomophones in lexical decision: No phonological activation in semantic dementia?
Directory of Open Access Journals (Sweden)
Maximiliano A. Wilson
The results in controls reproduce those found in literature (Braun et al., 2009. The general impairment and the lack of lexicality effect are also in line with current literature on svPPA and are likely explained by semantic impairment (Rogers et al., 2004. Interestingly, the novel result here is the absence of PsH effect in svPPA. This suggests that phonology is not correctly activated and that O-P mappings are also impaired in svPPA.
Interference of spoken word recognition through phonological priming from visual objects and printed words
McQueen, J.; Huettig, F.
Three cross-modal priming experiments examined the influence of pre-exposure to pictures and printed words on the speed of spoken word recognition. Targets for auditory lexical decision were spoken Dutch words and nonwords, presented in isolation (Experiments 1 and 2) or after a short phrase (Experiment 3). Auditory stimuli were preceded by primes which were pictures (Experiments 1 and 3) or those pictures' printed names (Experiment 2). Prime-target pairs were phonologically onsetrelated (e.g...

The interaction of tone with voicing and foot structure: evidence from Kera phonetics and phonology
Pearce, Mary Dorothy
This thesis uses acoustic measurements as a basis for the phonological analysis of the interaction of tone with voicing and foot structure in Kera (a Chadic language). In both tone spreading and vowel harmony, the iambic foot acts as a domain for spreading. Further evidence for the foot comes from measurements of duration, intensity and vowel quality. Kera is unusual in combining a tone system with a partially independent metrical system based on iambs. In words containing more than one foot, the foot is the tone bearing unit (TBU), but in shorter words, the TBU is the syllable. In perception and production experiments, results show that Kera speakers, unlike English and French, use the fundamental frequency as the principle cue to 'Voicing" contrast. Voice onset time (VOT) has only a minor role. Historically, tones probably developed from voicing through a process of tonogenesis, but synchronically, the feature voice is no longer contrastive and VOT is used in an enhancing role. Some linguists have claimed that Kera is a key example for their controversial theory of long-distance voicing spread. But as voice is not part of Kera phonology, this thesis gives counter-evidence to the voice spreading claim. An important finding from the experiments is that the phonological grammars are different between village women, men moving to town and town men. These differences are attributed to French contact. The interaction between Kera tone and voicing and contact with French have produced changes from a 2-way voicing contrast, through a 3-way tonal contrast, to a 2-way voicing contrast plus another contrast with short VOT. These diachronic and synchronic tone/voicing facts are analysed using laryngeal features and Optimality Theory. This thesis provides a body of new data, detailed acoustic measurements, and an analysis incorporating current theoretical issues in phonology, which make it of interest to Africanists and theoreticians alike.
Reconciling phonological neighborhood effects in speech production through single trial analysis
Sadat Schaffai, Jasmin, 1982-; Martin, Clara D.; Costa Martínez, Albert, 1970-; Alario, F.-Xavier (François -Xavier),
A crucial step for understanding how lexical knowledge is represented is to describe the relative similarity of lexical items, and how it influences language processing. Previous studies of the effects of form similarity on word production have reported conflicting results, notably within and across languages. The aim of the present study was to clarify this empirical issue to provide specific constraints for theoretical models of language production. We investigated the role of phonological ...
Logographic Kanji versus phonographic Kana in literacy acquisition: how important are visual and phonological skills?
Koyama, Maki S; Hansen, Peter C; Stein, John F
It is well-established that phonological skills are important for literacy acquisition in all scripts. However, the role of visual skills is less well understood. For logographic scripts in which a symbol represents a whole word or a meaningful unit, the importance of visual memory in literacy acquisition might be expected to be high because of the visual complexity of logographic characters, but in fact its role remains poorly understood. The Japanese writing system uses both phonographic "Kana" and logographic "Kanji" scripts concurrently and thus allows for the assessment of the contribution of phonological and visual processing to literacy acquisition in these two different scripts in the same language. We tested 74 Japanese children (39 second graders and 35 fourth graders) on a range of literacy, sensory, and cognitive tasks. We found that Kana literacy performance was significantly predicted by low-level sensory processing (both auditory frequency modulation sensitivity and visual motion sensitivity) as well as phonological awareness, but not by visual memory. This result is largely consistent with previous studies in other phonographic scripts such as English. In contrast, Kanji literacy performance was strongly predicted by visual memory (particularly visual long-term memory), but not by either low-level sensory processing or phonological awareness. Our results show differences in the skills that predict literacy performance in phonographic Kana and logographic Kanji, as well as providing experimental evidence that visual memory is important when learning Kanji. Therefore, children's literacy problems and remediation programs should be considered in the context of the script in which children are learning to read and write.
Shared neuroanatomical substrates of impaired phonological working memory across reading disability and autism

Background Individuals with reading disability and individuals with autism spectrum disorder (ASD) are characterized, respectively, by their difficulties in reading and social communication, but both groups often have impaired phonological working memory (PWM). It is not known whether the impaired PWM reflects distinct or shared neuroanatomical abnormalities in these two diagnostic groups.

Phonologically-Based Priming in the Same-Different Task With L1 Readers.
Lupker, Stephen J; Nakayama, Mariko; Yoshihara, Masahiro
The present experiment provides an investigation of a promising new tool, the masked priming same-different task, for investigating the orthographic coding process. Orthographic coding is the process of establishing a mental representation of the letters and letter order in the word being read which is then used by readers to access higher-level (e.g., semantic) information about that word. Prior research (e.g., Norris & Kinoshita, 2008) had suggested that performance in this task may be based entirely on orthographic codes. As reported by Lupker, Nakayama, and Perea (2015a), however, in at least some circumstances, phonological codes also play a role. Specifically, even though their 2 languages are completely different orthographically, Lupker et al.'s Japanese-English bilinguals showed priming in this task when masked L1 primes were phonologically similar to L2 targets. An obvious follow-up question is whether Lupker et al.'s effect might have resulted from a strategy that was adopted by their bilinguals to aid in processing of, and memory for, the somewhat unfamiliar L2 targets. In the present experiment, Japanese readers responded to (Japanese) Kanji targets with phonologically identical primes (on "related" trials) being presented in a completely different but highly familiar Japanese script, Hiragana. Once again, significant priming effects were observed, indicating that, although performance in the masked priming same-different task may be mainly based on orthographic codes, phonological codes can play a role even when the stimuli being matched are familiar words from a reader's L1.

Inhibitory processes, working memory, phonological awareness, naming speed, and early arithmetic achievement.
Navarro, Jose I; Aguilar, Manuel; Alcalde, Concepcion; Ruiz, Gonzalo; Marchena, Esperanza; Menacho, Inmaculada
This study identified the cognitive processes that underlie the individual differences in early mathematical performance in elementary school children. Taking into account the Baddeley framework multicomponent model, the inhibitory processes, working memory, phonological awareness, and naming speed are considered to be related to early math learning. To examine this relationship, we compared the performance of a total of 424 typically developing middle-class children, aged between 4 and 7 years in a battery of cognitive and early numeric tests: The Utrecht Early Numeracy Test, the Rapid Automatized Naming Test, Spanish version of the Stroop task, the Numeracy Interference Test, Digit Span test, and Phonological Knowledge Test. The mean age of the participants was 72.21 months (sd = 14.8), and 48.6% were male and 51.4% were female. The results demonstrated that children performing worst on central executive, phonological processing, and inhibitory processes showed lower results in early mathematical tasks measured by The Utrecht Early Numeracy Test. Results supported the notion that the executive system is an important predictor of children's mathematical performance.

Memory and phonological awareness in children with Benign Rolandic Epilepsy compared to a matched control group.
Northcott, Ellen; Connolly, Anne M; Berroya, Anna; McIntyre, Jenny; Christie, Jane; Taylor, Alan; Bleasel, Andrew F; Lawson, John A; Bye, Ann M E
In a previous study we demonstrated children with Benign Rolandic Epilepsy have normal intelligence and language ability. However, difficulties in verbal and visual memory and aspects of phonological awareness were found compared to normative data. To address the methodological limitations related to the use of normative data, we compared the same cohort of children with Benign Rolandic Epilepsy to a matched control group. Controls (n=40) matched on age and gender to the Benign Rolandic Epilepsy cohort underwent neuropsychological assessment. The life functioning of the control group was assessed using a modified version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). The study confirmed the previous findings of memory and phonological awareness difficulties. In addition, the children with Benign Rolandic Epilepsy had significantly lower IQ scores than the matched control group. Paired sample t-tests showed that on 8 of 11 QOLCE scales, children with Benign Rolandic Epilepsy were rated by parents as having poorer life functioning compared to matched controls, including lower parental ratings on the subscales of memory and language. Benign Rolandic Epilepsy has an excellent seizure prognosis, but this study further emphasizes potential cognitive difficulties. Using an age and gender matched control group, the previous findings of memory and phonological awareness difficulties were validated. These problems in cognition were also identified by parents of children with Benign Rolandic Epilepsy as problematic and impacting upon the child's quality of life.
Keeping it together: Semantic coherence stabilizes phonological sequences in short-term memory.
Savill, Nicola; Ellis, Rachel; Brooke, Emma; Koa, Tiffany; Ferguson, Suzie; Rojas-Rodriguez, Elena; Arnold, Dominic; Smallwood, Jonathan; Jefferies, Elizabeth
Our ability to hold a sequence of speech sounds in mind, in the correct configuration, supports many aspects of communication, but the contribution of conceptual information to this basic phonological capacity remains controversial. Previous research has shown modest and inconsistent benefits of meaning on phonological stability in short-term memory, but these studies were based on sets of unrelated words. Using a novel design, we examined the immediate recall of sentence-like sequences with coherent meaning, alongside both standard word lists and mixed lists containing words and nonwords. We found, and replicated, substantial effects of coherent meaning on phoneme-level accuracy: The phonemes of both words and nonwords within conceptually coherent sequences were more likely to be produced together and in the correct order. Since nonwords do not exist as items in long-term memory, the semantic enhancement of phoneme-level recall for both item types cannot be explained by a lexically based item reconstruction process employed at the point of retrieval ("redintegration"). Instead, our data show, for naturalistic input, that when meaning emerges from the combination of words, the phonological traces that support language are reinforced by a semantic-binding process that has been largely overlooked by past short-term memory research.
The phonological memory profile of preschool children who make atypical speech sound errors.
Waring, Rebecca; Eadie, Patricia; Rickard Liow, Susan; Dodd, Barbara
Previous research indicates that children with speech sound disorders (SSD) have underlying phonological memory deficits. The SSD population, however, is diverse. While children who make consistent atypical speech errors (phonological disorder/PhDis) are known to have executive function deficits in rule abstraction and cognitive flexibility, little is known about their memory profile. Sixteen monolingual preschool children with atypical speech errors (PhDis) were matched individually to age-and-gender peers with typically developing speech (TDS). The two groups were compared on forward recall of familiar words (pointing response), reverse recall of familiar words (pointing response), and reverse recall of digits (spoken response) and a receptive vocabulary task. There were no differences between children with TDS and children with PhDis on forward recall or vocabulary tasks. However, children with TDS significantly outperformed children with PhDis on the two reverse recall tasks. Findings suggest that atypical speech errors are associated with impaired phonological working memory, implicating executive function impairment in specific subtypes of SSD.
[The phonological variant of primary progressive aphasia, a single case study].
Diesfeldt, H F A
Primary progressive aphasia (PPA) is a neurodegenerative syndrome characterized by an insidious onset and gradual progression of deficits that can involve any aspect of language, including word finding, object naming, fluency, syntax, phonology and word comprehension. The initial symptoms occur in the absence of major deficits in other cognitive domains, including episodic memory, visuospatial abilities and visuoconstruction. According to recent diagnostic guidelines, PPA is typically divided into three variants: nonfluent variant PPA (also termed progressive nonfluent aphasia), semantic variant PPA (also termed semantic dementia) and logopenic/phonological variant PPA (also termed logopenic progressive aphasia). The paper describes a 79-yr old man, who presented with normal motor speech and production rate, impaired single word retrieval and phonemic errors in spontaneous speech and confrontational naming. Confrontation naming was strongly affected by lexical frequency. He was impaired on repetition of sentences and phrases. Reading was intact for regularly spelled words but not for irregular words (surface dyslexia). Comprehension was spared at the single word level, but impaired for complex sentences. He performed within the normal range on the Dutch equivalent of the Pyramids and Palm Trees (PPT) Pictures Test, indicating that semantic processing was preserved. There was, however, a slight deficiency on the PPT Words Test, which appeals to semantic knowledge of verbal associations. His core deficit was interpreted as an inability to retrieve stored lexical-phonological information for spoken word production in spontaneous speech, confrontation naming, repetition and reading aloud.
Language specificity of lexical-phonological therapy in bilingual aphasia: A clinical and electrophysiological study.
Radman, Narges; Spierer, Lucas; Laganaro, Marina; Annoni, Jean-Marie; Colombo, Françoise
Based on findings for overlapping representations of bilingual people's first (L1) and second (L2) languages, unilingual therapies of bilingual aphasia have been proposed to benefit the untrained language. However, the generalisation patterns of intra- and cross-language and phonological therapy and their neural bases remain unclear. We tested whether the effects of an intensive lexical-phonological training (LPT) in L2 transferred to L1 word production in a Persian-French bilingual stroke patient with Broca's aphasia. Language performance was assessed using the Bilingual Aphasia Test, a 144-item picture naming (PN) task and a word-picture verification (WPV) task. Electroencephalography (EEG) was recorded during PN and WPV in both languages before and after an LPT in French on a wordlist from the PN task. After the therapy, naming improved only for the treated L2 items. The naming performance improved neither in the untrained L2 items nor in the corresponding items in L1. EEG analyses revealed a Language x Session topographic interaction at 540 ms post-stimulus, driven by a modification of the electrophysiological response to the treated L2 but not L1 items. These results indicate that LPT modified the brain networks engaged in the phonological-phonetic processing during naming only in the trained language for the trained items.

Maryam Sadat Momen Vaghefi
Full Text Available Background and Aim: Phonological processing skills include the abilities to restore, retrieve and use memorized phonological codes. The purpose of this research is to compare and evaluate phonological processing skills in 6-7 year old blind and sighted Persian speakers in Tehran, Iran.Methods: This research is an analysis-comparison study. The subjects were 24 blind and 24 sighted children. The evaluation test of reading and writing disorders in primary school students, linguistic and cognitive abilities test, and the naming subtest of the aphasia evaluation test were used as research tools.Results: Sighted children were found to perform better on phoneme recognition of nonwords and flower naming subtests; and the difference was significant (p<0.001. Blind children performed better in words and sentence memory; the difference was significant (p<0.001. There were no significant differences in other subtests.Conclusion: Blind children's better performance in memory tasks is due to the fact that they have powerful auditory memory.
Nonword Repetition and Vocabulary Knowledge as Predictors of Children's Phonological and Semantic Word Learning.
Adlof, Suzanne M; Patten, Hannah
This study examined the unique and shared variance that nonword repetition and vocabulary knowledge contribute to children's ability to learn new words. Multiple measures of word learning were used to assess recall and recognition of phonological and semantic information. Fifty children, with a mean age of 8 years (range 5-12 years), completed experimental assessments of word learning and norm-referenced assessments of receptive and expressive vocabulary knowledge and nonword repetition skills. Hierarchical multiple regression analyses examined the variance in word learning that was explained by vocabulary knowledge and nonword repetition after controlling for chronological age. Together with chronological age, nonword repetition and vocabulary knowledge explained up to 44% of the variance in children's word learning. Nonword repetition was the stronger predictor of phonological recall, phonological recognition, and semantic recognition, whereas vocabulary knowledge was the stronger predictor of verbal semantic recall. These findings extend the results of past studies indicating that both nonword repetition skill and existing vocabulary knowledge are important for new word learning, but the relative influence of each predictor depends on the way word learning is measured. Suggestions for further research involving typically developing children and children with language or reading impairments are discussed.

Full Text Available This study aims to evaluate the effect of phonological awareness training program in preschool performance of 256 children in Funchal, Portugal. This is a longitudinal study from preschool (2005 to 4th grade (2011. It has an experimental design. The sample includes an Experimental Group (132 children and a Control group (124 children. We pretend to answer the following research question: To what degree does training children in phonological awareness as early as preschool have short-term and long-term effects on the evolution of students' competencies and disciplinary knowledge? A first evaluation done in 2006 on the effects of this program at the end of preschool education revealed that the Experimental Group presented significant improvements when compared to the Control Group on the considered dimensions. In 2011, the Experimental Group presented Math National Test higher significant results when compared to the Control Group. The Experimental Group's Portuguese National Test presented better results than the Control Group one, but not significantly. This seems to indicate that Phonological Awareness Program can bring benefits and prevent long-term math school failure.
The pressure suppression system
International Nuclear Information System (INIS)
Aust, E.
Nuclear plants with boiling water reactors have a safety containment with a pressure suppression system (PSS). Proceeding on significant self-developments, today the three PSS-lines of General Electric Co. (GE), Kraftwerk Union AG (KWU) and ASEA-ATOM are predominant, which are currently represented by the MARK III type, the KWU type 72 and the BWR 75 containment. In addition, there are special developments for the nuclear ship propulsion and for the pressurized water reactors in the Soviet Union. Key design values of the PSS allow a first valuation of its loads during a hypothetical loss-of-coolant accident. (orig.) [de
Newly-acquired words are more phonologically robust in verbal short-term memory when they have associated semantic representations.
Savill, Nicola; Ellis, Andrew W; Jefferies, Elizabeth
Verbal short-term memory (STM) is a crucial cognitive function central to language learning, comprehension and reasoning, yet the processes that underlie this capacity are not fully understood. In particular, although STM primarily draws on a phonological code, interactions between long-term phonological and semantic representations might help to stabilise the phonological trace for words ("semantic binding hypothesis"). This idea was first proposed to explain the frequent phoneme recombination errors made by patients with semantic dementia when recalling words that are no longer fully understood. However, converging evidence in support of semantic binding is scant: it is unusual for studies of healthy participants to examine serial recall at the phoneme level and also it is difficult to separate the contribution of phonological-lexical knowledge from effects of word meaning. We used a new method to disentangle these influences in healthy individuals by training new 'words' with or without associated semantic information. We examined phonological coherence in immediate serial recall (ISR), both immediately and the day after training. Trained items were more likely to be recalled than novel nonwords, confirming the importance of phonological-lexical knowledge, and items with semantic associations were also produced more accurately than those with no meaning, at both time points. For semantically-trained items, there were fewer phoneme ordering and identity errors, and consequently more complete target items were produced in both correct and incorrect list positions. These data show that lexical-semantic knowledge improves the robustness of verbal STM at the sub-item level, even when the effect of phonological familiarity is taken into account.

In a radiation release suppression system upon accident, an electromotive valve, a pneumatic operation valve or a manual operation valve is disposed to gas ventilation pipelines which are extended from both of a dry well and a wet well of a reactor container to a stuck. In addition, a combination filter of a metal fiber filter made of stainless steel etc. and an activated carbon fiber filter is disposed in the midway of pipelines in a reactor building. With such a constitution, the inside of the container can be depressurized (prevention of ruptures) and the amount of radioactive substances released to circumstances is remarkably suppressed by the effect of radioactive substance capturing effect of the metal fiber filter made of stainless steel etc. disposed in the vent pipe in the container and a radioactive substance capturing effect by the combination filter of the metal fiber filter made of stainless steel, etc. and the activated carbon fiber filter disposed in the gas ventilation pipelines even upon occurrence of an accident exceeding design basis.

We show that the recent Planck limits on primordial non-Gaussianity impose strong constraints on light hidden sector fields coupled to the inflaton via operators suppressed by a high mass scale Λ. We study a simple effective field theory in which a hidden sector field is coupled to a shift-symmetric inflaton via arbitrary operators up to dimension five. Self-interactions in the hidden sector lead to non-Gaussianity in the curvature perturbations. To be consistent with the Planck limit on local non-Gaussianity, the coupling to any hidden sector with light fields and natural cubic couplings must be suppressed by a very high scale Λ > 10 5 H. Even if the hidden sector has Gaussian correlations, nonlinearities in the mixing with the inflaton still lead to non-Gaussian curvature perturbations. In this case, the non-Gaussianity is of the equilateral or orthogonal type, and the Planck data requires Λ > 10 2 H
An exploratory study of phonological awareness and working memory differences and literacy performance of people that use AAC.
Gómez Taibo, María Luisa; Vieiro Iglesias, Pilar; González Raposo, María del Salvador; Sotillo Méndez, María
Twelve cerebral palsied adolescents and young adults with complex communicative needs who used augmentative and alternative communication were studied. They were classified according to their working memory capacity (high vs. low) into two groups of 6 participants. They were also divided into two groups of 6 participants according to their high vs. low phonological skills. These groups were compared on their performance in reading tests -orthographic knowledge, a word test and a pseudoword reading test- and in the spelling of words, pseudowords and pictures' names. Statistical differences were found between high vs. low phonological skills groups, and between high and low working memory groups. High working memory capacity group scored significantly higher than low working memory group in the orthographic and word reading tests. The high phonological skills group outperformed the low phonological skills group in the word reading test and in the spelling of pseudowords and pictures' names. From a descriptive point of view, phonological skills and working memory, factors known to be highly predictive of literacy skills in people without disabilities, also hold as factors for the participants that used AAC in our study. Implications of the results are discussed.
Early Parallel Activation of Semantics and Phonology in Picture Naming: Evidence from a Multiple Linear Regression MEG Study.
Miozzo, Michele; Pulvermüller, Friedemann; Hauk, Olaf
The time course of brain activation during word production has become an area of increasingly intense investigation in cognitive neuroscience. The predominant view has been that semantic and phonological processes are activated sequentially, at about 150 and 200-400 ms after picture onset. Although evidence from prior studies has been interpreted as supporting this view, these studies were arguably not ideally suited to detect early brain activation of semantic and phonological processes. We here used a multiple linear regression approach to magnetoencephalography (MEG) analysis of picture naming in order to investigate early effects of variables specifically related to visual, semantic, and phonological processing. This was combined with distributed minimum-norm source estimation and region-of-interest analysis. Brain activation associated with visual image complexity appeared in occipital cortex at about 100 ms after picture presentation onset. At about 150 ms, semantic variables became physiologically manifest in left frontotemporal regions. In the same latency range, we found an effect of phonological variables in the left middle temporal gyrus. Our results demonstrate that multiple linear regression analysis is sensitive to early effects of multiple psycholinguistic variables in picture naming. Crucially, our results suggest that access to phonological information might begin in parallel with semantic processing around 150 ms after picture onset. © The Author 2014.

The role of semantic and phonological factors in word recognition: an ERP cross-modal priming study of derivational morphology.
Kielar, Aneta; Joanisse, Marc F
Theories of morphological processing differ on the issue of how lexical and grammatical information are stored and accessed. A key point of contention is whether complex forms are decomposed during recognition (e.g., establish+ment), compared to forms that cannot be analyzed into constituent morphemes (e.g., apartment). In the present study, we examined these issues with respect to English derivational morphology by measuring ERP responses during a cross-modal priming lexical decision task. ERP priming effects for semantically and phonologically transparent derived words (government-govern) were compared to those of semantically opaque derived words (apartment-apart) as well as "quasi-regular" items that represent intermediate cases of morphological transparency (dresser-dress). Additional conditions independently manipulated semantic and phonological relatedness in non-derived words (semantics: couch-sofa; phonology: panel-pan). The degree of N400 ERP priming to morphological forms varied depending on the amount of semantic and phonological overlap between word types, rather than respecting a bivariate distinction between derived and opaque forms. Moreover, these effects could not be accounted for by semantic or phonological relatedness alone. The findings support the theory that morphological relatedness is graded rather than absolute, and depend on the joint contribution of form and meaning overlap. Copyright © 2010 Elsevier Ltd.

Tap and trill clusters in typical and protracted phonological development: Challenging segments in complex phonological environments. Introduction to the special issue.
Stemberger, Joseph Paul; Bernhardt, Barbara May
The papers in this crosslinguistic issue address children's acquisition of word-initial rhotic clusters in languages with taps/trills, that is, the acquisition of challenging segments in complex environments. Several papers also include comparisons with singleton rhotics and/or /l/ as a singleton or in clusters. The studies are part of a larger investigation that uses similar methodologies across languages in order to enhance crosslinguistic comparability (Bernhardt and Stemberger, 2012, 2015). Participants for the current studies were monolingual preschoolers with typical or protracted phonological development who speak one of the following languages: Germanic (Icelandic/Swedish); Romance (Portuguese/Spanish); Slavic (Bulgarian/Slovenian) and Finno-Ugric (Hungarian). This introductory paper describes characteristics of taps/trills and general methodology across the studies, concluding with predicted patterns of acquisition. The seven papers that follow are in a sense the 'results' for this introduction. A concluding paper discusses major findings and their implications for theory, research and clinical practice.

Full Text Available This study measures letter naming, phonological awareness, and spelling knowledge in 2,100 kindergarten students attending 63 schools within a large, urban school district. Students were assessed across December, February, and May of the kindergarten year. Results found that, by May, 71.8% of students had attained full letter naming knowledge. Phonological awareness emerged more slowly with 48% of students able to reliably segment and blend phonemes in words. Spelling development, a measure of phonics knowledge, found that, by May, 71.8% of students were in the partial-alphabetic phase. A series of regression analyses revealed that by the end of kindergarten both letter naming and phonological awareness were significant predictors of spelling knowledge (b = .332 and .518 for LK and PA, resp., explaining 52.7% of the variance.
Auditory processing and phonological awareness skills of five-year-old children with and without musical experience.
Escalda, Júlia; Lemos, Stela Maris Aguiar; França, Cecília Cavalieri
To investigate the relations between musical experience, auditory processing and phonological awareness of groups of 5-year-old children with and without musical experience. Participants were 56 5-year-old subjects of both genders, 26 in the Study Group, consisting of children with musical experience, and 30 in the Control Group, consisting of children without musical experience. All participants were assessed with the Simplified Auditory Processing Assessment and Phonological Awareness Test and the data was statistically analyzed. There was a statistically significant difference between the results of the sequential memory test for verbal and non-verbal sounds with four stimuli, phonological awareness tasks of rhyme recognition, phonemic synthesis and phonemic deletion. Analysis of multiple binary logistic regression showed that, with exception of the sequential verbal memory with four syllables, the observed difference in subjects' performance was associated with their musical experience. Musical experience improves auditory and metalinguistic abilities of 5-year-old children.
Influence of timing of two-stage palate closure on early phonological and lexical development in children with cleft palate
DEFF Research Database (Denmark)
Willadsen, Elisabeth
BACKGROUND AND PURPOSE Numerous studies have indicated that early closure of the palatal cleft has a positive influence on the phonological development in children with cleft palate. So far, however, substantial evidence for this assumption has been lacking due to a variety of weaknesses...... of the studies conducted, including the lack of randomized clinical trials (RCT) (Peterson-Falzone 1996). A prospective RCT was conducted to add to the knowledge of the influence of timing of hard palate closure on early phonological and lexical development from 1 to 3 years. METHODS Fourty-one children...... were video-recorded during a play interaction with a parent, and the video-recordings were transcribed in IPA. At 36 months, a naming test was administered. RESULTS At 18 months, the phonological development in the early group was more similar to that of the control group, than that of the late group...
Orthographic familiarity, phonological legality and number of orthographic neighbours affect the onset of ERP lexical effects
Directory of Open Access Journals (Sweden)
Adorni Roberta
Full Text Available Abstract Background It has been suggested that the variability among studies in the onset of lexical effects may be due to a series of methodological differences. In this study we investigated the role of orthographic familiarity, phonological legality and number of orthographic neighbours of words in determining the onset of word/non-word discriminative responses. Methods ERPs were recorded from 128 sites in 16 Italian University students engaged in a lexical decision task. Stimuli were 100 words, 100 quasi-words (obtained by the replacement of a single letter, 100 pseudo-words (non-derived and 100 illegal letter strings. All stimuli were balanced for length; words and quasi-words were also balanced for frequency of use, domain of semantic category and imageability. SwLORETA source reconstruction was performed on ERP difference waves of interest. Results Overall, the data provided evidence that the latency of lexical effects (word/non-word discrimination varied as a function of the number of a word's orthographic neighbours, being shorter to non-derived than to derived pseudo-words. This suggests some caveats about the use in lexical decision paradigms of quasi-words obtained by transposing or replacing only 1 or 2 letters. Our findings also showed that the left-occipito/temporal area, reflecting the activity of the left fusiform gyrus (BA37 of the temporal lobe, was affected by the visual familiarity of words, thus explaining its lexical sensitivity (word vs. non-word discrimination. The temporo-parietal area was markedly sensitive to phonological legality exhibiting a clear-cut discriminative response between illegal and legal strings as early as 250 ms of latency. Conclusion The onset of lexical effects in a lexical decision paradigm depends on a series of factors, including orthographic familiarity, degree of global lexical activity, and phonologic legality of non-words.
Phonological ambiguity modulates resolution of semantic ambiguity during reading: An fMRI study of Hebrew.
Bitan, Tali; Kaftory, Asaf; Meiri-Leib, Adi; Eviatar, Zohar; Peleg, Orna
The current fMRI study examined the role of phonology in the extraction of meaning from print in each hemisphere by comparing homophonic and heterophonic homographs (ambiguous words in which both meanings have the same or different sounds respectively, e.g., bank or tear). The analysis distinguished between the first phase, in which participants read ambiguous words without context, and the second phase in which the context resolves the ambiguity. Native Hebrew readers were scanned during semantic relatedness judgments on pairs of words in which the first word was either a homophone or a heterophone and the second word was related to its dominant or subordinate meaning. In Phase 1 there was greater activation for heterophones in left inferior frontal gyrus (IFG), pars opercularis, and more activation for homophones in bilateral IFG pars orbitalis, suggesting that resolution of the conflict at the phonological level has abolished the semantic ambiguity for heterophones. Reduced activation for all ambiguous words in temporo-parietal regions suggests that although ambiguity enhances controlled lexical selection processes in frontal regions it reduces reliance on bottom-up mapping processes. After presentation of the context, a larger difference between the dominant and subordinate meaning was found for heterophones in all reading-related regions, suggesting a greater engagement for heterophones with the dominant meaning. Altogether these results are consistent with the prominent role of phonological processing in visual word recognition. Finally, despite differences in hemispheric asymmetry between homophones and heterophones, ambiguity resolution, even toward the subordinate meaning, is largely left lateralized.

Phonological Working Memory in 4-8 Year-Old Persian Children Who stutter
Directory of Open Access Journals (Sweden)
Maryam Vahab
Full Text Available Background: One language-related area that has recently received more attention from researchers working in the field of stuttering is phonological working memory. This article aimed to identify phonological skills of working memory in children with stuttering in comparison with normal children, and to obtain the relationship between the increase in the number of syllables in nonwords and the mean percentage of error in non-word repetition in both groups, then to compare them with each other. Methods: Thirty children participated in the study, 15 children who stutter and 15 normal children which were matched by age, gender and socio-economic status. Cases of this study were recruited by non random convenience sampling. The research data collection was based on non-word repetition test. The test included 40 non-words. Independent t-tests and linear regression were used for data analysis. Results: Results revealed that in all cases the mean percentage of error was higher in children who stutter than normal children, but the difference was not statistically significant (P>0.05. Also the mean percentage error did not show a regular increase by increasing the number of syllables in the non-words. So that, in both groups of the study the highest mean percentage of error was related to single-syllable non-words then three-syllable and two-syllable ones. Conclusion: The results of the present research from previous researches support the view that children with stuttering may have some degree of delay and slow in phonological working memory abilities when compared to normal children. It is proposed that in future more researches could be done in more samples, in different age groups of children and adults who stutter.
FMRI of past tense processing: the effects of phonological complexity and task difficulty.
Desai, Rutvik; Conant, Lisa L; Waldron, Eric; Binder, Jeffrey R
The generation of regular and irregular past tense verbs has been an important issue in cognitive science and has been used to advance different models of the organization of language in the brain. The dual-system view holds that the regular past tense forms are generated by a rule while irregular forms are retrieved from memory. The single-system view, on the other hand, holds that both forms are generated by a single integrated system and differ only in their reliance on factors such as phonology and semantics. We conducted an event-related fMRI study to examine the activation patterns associated with the generation and reading of regular and irregular past tense forms, in addition to the reading of their stems. Regular and irregular past tense generation activated similar brain regions compared to the reading of their respective stems. The areas activated more for irregular generation compared to regular generation included inferior frontal, precentral, and parietal regions bilaterally. This activation can be interpreted as reflecting the greater attentional and response selection demands of irregular generation. Compared to irregular generation, regular generation activated a small region in the left superior temporal gyrus when the regular and irregular past tense forms were mismatched on phonological complexity. No areas were more activated for regulars than irregulars when the past tense forms were matched on this variable. This suggests that the activation specific to regulars was related to the higher phonological complexity of their past tense forms rather than to their generation. A contrast of the reading of regular and irregular past tense forms was consistent with this hypothesis. These results support a single-system account of past tense generation.
Development of phonological constancy: 19-month-olds, but not 15-month-olds, identify words in a non-native regional accent.
Mulak, Karen E; Best, Catherine T; Tyler, Michael D; Kitamura, Christine; Irwin, Julia R
By 12 months, children grasp that a phonetic change to a word can change its identity (phonological distinctiveness). However, they must also grasp that some phonetic changes do not (phonological constancy). To test development of phonological constancy, sixteen 15-month-olds and sixteen 19-month-olds completed an eye-tracking task that tracked their gaze to named versus unnamed images for familiar words spoken in their native (Australian) and an unfamiliar non-native (Jamaican) regional accent of English. Both groups looked longer at named than unnamed images for Australian pronunciations, but only 19-month-olds did so for Jamaican pronunciations, indicating that phonological constancy emerges by 19 months. Vocabulary size predicted 15-month-olds' identifications for the Jamaican pronunciations, suggesting vocabulary growth is a viable predictor for phonological constancy development. © 2013 The Authors.

Phonological sketch and classification of Lawu, an undocumented Ngwi language of Yunnan
Directory of Open Access Journals (Sweden)
Cathryn Yang
Full Text Available Lawu is a severely endangered, undocumented Ngwi (Loloish language spoken in Yunnan, China. This paper presents a preliminary sketch of Lawu phonology based on lexico-phonetic data recorded from two speakers in 2008, with special attention to the tone splits and mergers that distinguish Lawu from other Ngwi languages. All tone categories except Proto-Ngwi Tone *3, a mid level pitch, have split, conditioned by the voicing of the initial segment. In the conditioning and effect of these tone splits, Lawu shows affinity with other Central Ngwi languages such as Lisu and Lahu and is provisionally classified as a Central Ngwi language.
Sensitivity to phonological context in L2 spelling: evidence from Russian ESL speakers
DEFF Research Database (Denmark)
Dich, Nadya
The study attempts to investigate factors underlying the development of spellers' sensitivity to phonological context in English. Native English speakers and Russian speakers of English as a second language (ESL) were tested on their ability to use information about the coda to predict the spelling...... on the information about the coda when spelling vowels in nonwords. In both native and non-native speakers, context sensitivity was predicted by English word spelling; in Russian ESL speakers this relationship was mediated by English proficiency. L1 spelling proficiency did not facilitate L2 context sensitivity...

Phonologically based assessment and intervention in Spastic Cerebral Palsy: A case analysis
Directory of Open Access Journals (Sweden)
Michael A. Crary
Full Text Available The articulation errors of one adult subject demonstrating a spastic variety of congenital cerebral palsy were evaluated via a phonological process analysis. This analysis indicated that a stopping process (replacement of fricatives with homorganic stops was the most detrimental to the subject's, intelligibility. Subsequent to this analysis a phonemic contrasting programme was initiated toward the goal of minimizing the influence of the stopping process. Results of spontaneous speech sample analyses indicated that this approach was successful in increasing the percentage of correctly produced fricative patterns. Success in this case suggests the applicability of a linguistically based intervention approach in structural/functional disturbances of speech articulation.

Full Text Available The paper describes, on the basis of original field research, the phonology of the local dialect of Šimljanik, which belongs to the iekavian north Moslavian (sjevernomoslavački kajkavian group of dialects. Since this is an area near the border between the kajkavian and štokavian groups of dialects, and whose original demographic structure has changed due to migration in the past, it is expected that many deviations from the typical kajkavian systems will be found. We will try to see whether (and in which way the štokavian elements have influenced the vowel, consonant and the accentuation systems.
Phonological inconsistency in word naming: Determinants of the interference effect between languages
Smits, E.M.G.; Sandra, D.M.J.; Martensen, H.E.; Dijkstra, A.F.J.
Dutch-English participants named words and nonwords having a between-language phonologically inconsistent rime, e.g., GREED and PREED, and control words with a language-typical rime, e.g., GROAN, in a monolingual stimulus list or in a mixed list containing Dutch words. Inconsistent items had longer latencies and more errors than typical items in the mixed lists but not in the pure list. The consistency effect depended on word frequency, but not on language membership, lexicality, or instructi...

Full Text Available Objective: Phonological Awareness (PA is a extra linguistic skill and defined as individual awareness of constituent's sounds of the word . This skill is a prerequisites of learning to Read. Many researchers suggested reciprocal relation between PA and Reading. This research determined level of PA-fundamental ability of reading-in normal first grade femal students of Isfahan & shahinshar to compare two current method of Reading that are used in educational system of Iran. Materials & Methods: The method used in this research is cross-sectional, descriptive-analytic and was done by 106 first grade female students who were normal and selected randomly in Isfahan & shahinshar cities. 51 students had teached by phonetic method and rest of them had teached by whole word method. The selection way of children was: this children had not any articulation, vision, reading, learning and cranial nerve disorders and this children investigated by Phonological Awareness test. scores of children by test calculated and this scores analyzed by t-test in Spss software. Results: The mean score of phonological awareness in phonetic method was 51.98 and in whole word method was 57.46. There was a significant differences between them in their scores (P=0.047. In addition,within subtests of phonological awareness task,mean score of first phoneme omission in whole word method was 4.84 and in phonetic method was 3.33. There was a significant difference between them in their scores (P=0.001. In the rest of subtests was no significant difference between them. Conclusion: Based on this study, a significant correlation could be found in Phonological Awareness between both group and in other hand, there was a significant correlation between scores of first phoneme omission in both groups (Whole word and Phonetic method.Based on importance of phonological awareness as a predictor of reading, we suggest more research in this outline must be done.
Reading, writing, and phonological processing skills of adolescents with 10 or more years of cochlear implant experience.
Geers, Ann E; Hayes, Heather
This study had three goals: (1) to document the literacy skills of deaf adolescents who received cochlear implants (CIs) as preschoolers; (2) to examine reading growth from elementary grades to high school; (3) to assess the contribution of early literacy levels and phonological processing skills, among other factors, to literacy levels in high school. A battery of reading, spelling, expository writing, and phonological processing assessments were administered to 112 high school (CI-HS) students, ages 15.5 to 18.5 yrs, who had participated in a reading assessment battery in early elementary grades (CI-E), ages 8.0 to 9.9 yrs. The CI-HS students' performance was compared with either a control group of hearing peers (N = 46) or hearing norms provided by the assessment developer. Many of the CI-HS students (47 to 66%) performed within or above the average range for hearing peers on reading tests. When compared with their CI-E performance, good early readers were also good readers in high school. Importantly, the majority of CI-HS students maintained their reading levels over time compared with hearing peers, indicating that the gap in performance was, at the very least, not widening for most students. Written expression and phonological processing tasks posed a great deal of difficulty for the CI-HS students. They were poorer spellers, poorer expository writers, and displayed poorer phonological knowledge than hearing age-mates. Phonological processing skills were a critical predictor of high school literacy skills (reading, spelling, and expository writing), accounting for 39% of variance remaining after controlling for child, family, and implant characteristics. Many children who receive CIs as preschoolers achieve age-appropriate literacy levels as adolescents. However, significant delays in spelling and written expression are evident compared with hearing peers. For children with CIs, the development of phonological processing skills is not just important for
Phonological, temporal and spectral processing in vowel length discrimination is impaired in German primary school children with developmental dyslexia.
Steinbrink, Claudia; Klatte, Maria; Lachmann, Thomas
It is still unclear whether phonological processing deficits are the underlying cause of developmental dyslexia, or rather a consequence of basic auditory processing impairments. To avoid methodological confounds, in the current study the same task and stimuli of comparable complexity were used to investigate both phonological and basic auditory (temporal and spectral) processing in dyslexia. German dyslexic children (Grades 3 and 4) were compared to age- and grade-matched controls in a vowel length discrimination task with three experimental conditions: In a phonological condition, natural vowels were used, differing both with respect to temporal and spectral information (in German, vowel length is phonemic, and vowel length differences are characterized by both temporal and spectral information). In a temporal condition, spectral information differentiating between the two vowels of a pair was eliminated, whereas in a spectral condition, temporal differences were removed. As performance measure, the sensitivity index d' was computed. At the group level, dyslexic children's performance was inferior to that of controls for phonological as well as temporal and spectral vowel length discrimination. At an individual level, nearly half of the dyslexic sample was characterized by deficits in all three conditions, but there were also some children showing no deficits at all. These results reveal on the one hand that phonological processing deficits in dyslexia may stem from impairments in processing temporal and spectral information in the speech signal. On the other hand they indicate, however, that not all dyslexic children might be characterized by phonological or auditory processing deficits. Copyright © 2014 Elsevier Ltd. All rights reserved.
Language structures used by kindergartners with cochlear implants: relationship to phonological awareness, lexical knowledge and hearing loss.
Nittrouer, Susan; Sansom, Emily; Low, Keri; Rice, Caitlin; Caldwell-Tarr, Amanda
Listeners use their knowledge of how language is structured to aid speech recognition in everyday communication. When it comes to children with congenital hearing loss severe enough to warrant cochlear implants (CIs), the question arises of whether these children can acquire the language knowledge needed to aid speech recognition, in spite of only having spectrally degraded signals available to them. That question was addressed in the present study. Specifically, there were three goals: (1) to compare the language structures used by children with CIs to those of children with normal hearing (NH); (2) to assess the amount of variance in the language measures explained by phonological awareness and lexical knowledge; and (3) to assess the amount of variance in the language measures explained by factors related to the hearing loss itself and subsequent treatment. Language samples were obtained and transcribed for 40 children who had just completed kindergarten: 19 with NH and 21 with CIs. Five measures were derived from Systematic Analysis of Language Transcripts: (1) mean length of utterance in morphemes, (2) number of conjunctions, excluding and, (3) number of personal pronouns, (4) number of bound morphemes, and (5) number of different words. Measures were also collected on phonological awareness and lexical knowledge. Statistics examined group differences, as well as the amount of variance in the language measures explained by phonological awareness, lexical knowledge, and factors related to hearing loss and its treatment for children with CIs. Mean scores of children with CIs were roughly one standard deviation below those of children with NH on all language measures, including lexical knowledge, matching outcomes of other studies. Mean scores of children with CIs were closer to two standard deviations below those of children with NH on two out of three measures of phonological awareness (specifically those related to phonemic structure).

Purpose: To provide a pressure suppression device for a gas cooled reactor wherein the coolant is discharged in a reactor building by a loss-of-coolant accident or the like, the increase in the pressure and temperature is controlled and thermal energy of the discharged coolant of high temperature and high pressure can be absorbed. Constitution: A low heat source unit is provided at the upper part in an inner space of a reactor building provided around the reactor, and at the upper part of the low heat source unit a stirring fan for mixing gas within the building, and a low heat source circulating the low heat source through a pipe is connected to the low heat source unit. The low heat source unit is provided with the pipe arranged in a spiral shape at the upper part of the space of the unit, and a large number of fins are provided at the outer surface of the pipe for increasing the transmission area and improve the heat exchange. When the coolant of high temperature and high pressure has been lost in the building, the thermal energy of the coolant is absorbed by the low heat source unit. (Aizawa, K.)
Using stochastic language models (SLM) to map lexical, syntactic, and phonological information processing in the brain.
Lopopolo, Alessandro; Frank, Stefan L; van den Bosch, Antal; Willems, Roel M
Language comprehension involves the simultaneous processing of information at the phonological, syntactic, and lexical level. We track these three distinct streams of information in the brain by using stochastic measures derived from computational language models to detect neural correlates of phoneme, part-of-speech, and word processing in an fMRI experiment. Probabilistic language models have proven to be useful tools for studying how language is processed as a sequence of symbols unfolding in time. Conditional probabilities between sequences of words are at the basis of probabilistic measures such as surprisal and perplexity which have been successfully used as predictors of several behavioural and neural correlates of sentence processing. Here we computed perplexity from sequences of words and their parts of speech, and their phonemic transcriptions. Brain activity time-locked to each word is regressed on the three model-derived measures. We observe that the brain keeps track of the statistical structure of lexical, syntactic and phonological information in distinct areas.
Treatment of Phonological Disorder: A Feasibility Study With Focus on Outcome Measures.
Smit, Ann Bosma; Brumbaugh, Klaire Mann; Weltsch, Barbara; Hilgers, Melanie
In a feasibility study for a randomized controlled trial of treatments for phonological disorders conducted over a period of 8 months, we examined 6 clinically relevant outcome measures. We took steps to reduce error variance and to maximize systematic variance. Six children received traditional treatment (Van Riper, 1939), and 7 received expansion points (Smit, 2000), a treatment program with both phonological and traditional elements. Outcome measures, which were applied to both word list and conversational samples, included percentage of consonants correct (PCC; Shriberg & Kwiatkowski, 1982), PCC for late and/or difficult (L/D) consonants and number of L/D consonants acquired. In repeated-measures analyses of variance, all measures showed significant differences from pretreatment to posttreatment, and the word list measures were associated with very high power values. In analyses of covariance for between-groups contrasts, the adjusted expansion points mean exceeded the adjusted traditional treatment mean for every measure; however, no differences reached significance. For the L/D PCC (conversation) measure, the contrast between groups was associated with a large effect size. We recommend that practitioners use outcome measures related to a word list. We recommend that researchers consider using L/D PCC on the basis of conversational samples to detect differences among treatment groups. https://doi.org/10.23641/asha.5872677.
Phonological processing of ignored distractor pictures, an fMRI investigation.
Bles, Mart; Jansma, Bernadette M
Neuroimaging studies of attention often focus on interactions between stimulus representations and top-down selection mechanisms in visual cortex. Less is known about the neural representation of distractor stimuli beyond visual areas, and the interactions between stimuli in linguistic processing areas. In the present study, participants viewed simultaneously presented line drawings at peripheral locations, while in the MRI scanner. The names of the objects depicted in these pictures were either phonologically related (i.e. shared the same consonant-vowel onset construction), or unrelated. Attention was directed either at the linguistic properties of one of these pictures, or at the fixation point (i.e. away from the pictures). Phonological representations of unattended pictures could be detected in the posterior superior temporal gyrus, the inferior frontal gyrus, and the insula. Under some circumstances, the name of ignored distractor pictures is retrieved by linguistic areas. This implies that selective attention to a specific location does not completely filter out the representations of distractor stimuli at early perceptual stages.
