Systematic sound preference in phonological disorders: a case study.

Systematic sound preference, where a group of sounds with the same manner of articulation is represented by one or two sounds in the production, is one of the characteristics of children with phonological disorders. This article examines the hypotheses advanced by Weiner (1981) for the phenomenon in the light of the data from a 7-year old Portuguese speaking child. The findings support some of the hypotheses, while providing counter evidence for one of them. They also point to the importance of word position and stress patterns in the systematicity of systematic sound preference.
