Phonological awareness and phonemic perception in 4-year-old children with delayed expressive phonology skills.
The purpose of this study was to compare the phonological awareness abilities of 2 groups of 4-year-old children: one with normally developing speech and language skills and the other with moderately or severely delayed expressive phonological skills but age-appropriate receptive vocabulary skills. Each group received tests of articulation, receptive vocabulary, phonemic perception, early literacy, and phonological awareness skills. The groups were matched for receptive language skills, age, socioeconomic status, and emergent literacy knowledge. The children with expressive phonological delays demonstrated significantly poorer phonemic perception and phonological awareness skills than their normally developing peers. The results suggest that preschool children with delayed expressive phonological abilities should be screened for their phonological awareness skills even when their language skills are otherwise normally developing.
