Electronic Theses and Dissertations

The purpose of the present study was to compare feature retention patterns between children developing speech typically (TD) and children with phonological impairment (PI) and to discuss these findings in terms of characteristics, severity, and implication for the identification of developmental apraxia of speech (DAS). A second purpose was to determine if a relationship exists between phonological knowledge and feature retention.

There were no significant differences …
