Abstract

The purpose of this study was to investigate the differences among children with developmental apraxia of speech (DAS Group), children with functional articulation disorders (FAD Group), and children with normal articulation (NA Group) on a receptive test of phonological rules.

Twenty-eight six- and seven-year-old male children, eight with developmental apraxia, ten with functional articulation disorders, and ten with normal articulation skills were selected for this study, All children had normal intelligence, normal hearing, normal auditory discrimination, and no neurological dysfunction or gross structural deviations of the oral speech mechanism. Three additional measures were utilized to place the subjects into the DAS, FAD, and NA Groups. Each subject was administered the Templin-Darley Screening Test of Articulation, the Isolated Volitional Oral Movements test, and selected items from The Fletcher Time-by-Count Test of Diadocho-kinetic Syllable Rate.

Following the selection procedures, all subjects were administered the test of Implicit Phonology, test consisted of paired items that contained phoneme combinations with either one or two consonant clusters "possible" in English words and its "impossible" alternative. From these pairs of meaningless phoneme combinations, the subjects were instructed to choose the combination that sounded more like a real “word.” The results of this study indicated that children alternative with developmental apraxia of speech performed like children with normal articulation skills and significantly better than did children with functional articulation disorders on the test of Implicit Phonology. Implications for therapy and future research are discussed.
