Feature Retention and Phonological Knowledge across Children with Suspected Developmental Apraxia of Speech, Phonological Impairment, and Typically Developing Speech.

<p>The purpose of this research effort was to examine whether the feature retention patterns and phonological knowledge of children with suspected apraxia of speech (AOSc) in comparison to those of children with phonological impairment (PI). A second purpose was to determine if a relationship exists between phonological knowledge and feature retention.</p><p>The study consisted of three groups of children: PI, AOSc, and typically developing (TD), ages four to seven. A 245-item speech sample was collected from each group. Feature retention percentages and phonological knowledge, represented by percent correct underlying representations (PCUR) were calculated for each child.</p><p>All groups retained place the least, followed by manner, with voicing being retained most. The null hypothesis was confirmed, with PI and AOSc groups exhibiting no significant differences across feature retention percentages or phonological knowledge. The positive correlation of voicing retention and PCUR of the AOSc group was the only significant relationship found.</p>
