Extrametricality and second language acquisition

This pilot study investigates the second language acquisition (SLA) of stress in Portuguese (L2) by native speakers of English (L1). In particular, it examines the interaction between extrametricality and default stress through two judgement tasks. Stress is suprasegmental, relative and involves a variety of phonetic correlates: Cross-linguistically, stressed syllables tend to be realized with higher pitch, longer duration and greater intensity—but languages differ as to which of these correlates is more or less signiﬁcant. Phonologically, stress presents some unique characteristics, such as the absence of a categorical feature [±stress]. Languages may also differ as to whether syllable shape affects stress (weight-sensitive) or not (weight-insensitive). Second language learners (L2ers) have to deal with such variability and, more importantly, have to acquire new stress patterns—some of which are often vastly different (even contradictory) when compared to the patterns (and phonetic cues) in their L1.
