A Study of the Acquisition of Fricatives By Three-Year-Old Children Learning Mexican Spanish

Spontaneous picture naming and imitated-sentence responses of six three-year-old monolingual Spanish speaking Mexican children were examined for their sound patterns in the acquisition of the fricatives /x/, /f/ and /s/. The data tend to support the position that children learning the phonology of a particular language may produce forms exemplifying a) constraints by a geographical dialect, b) examples of general developmental processes across languages, and c) variability across children both in their stage of development and individual patterns for dealing with the adult forms of the language being learned.
