The Role of Phonotactic Frequency in Sentence Repetition by Children With Specific Language Impairment
Conclusion: Children with SLI repeated CVC target words less accurately overall but showed similar sensitivity to PPF as typical controls, suggesting that PPF affects repetition of real words embedded in sentential contexts by both children with SLI and typically developing peers.
An On-Line Imitative Test of Speech-Pattern Contrast Perception (OlimSpac): Developmental Effects in Normally Hearing Children
Conclusions: When evaluated on a pass/fail basis, normally hearing children 3 years of age or older are likely to demonstrate auditory perception of most phonemic contrasts using this imitative test. Phonological development and other task-related factors have only a modest effect on performance by normally hearing children after 3 years of age. The effects of hearing loss, hearing age, sensory assistance, and listening experience in children with hearing loss remain to be determined.
Conclusion: Overall, the studies indicate that SSL is a reliable measure that increases as children develop. Children with language impairment exhibit lower SSL scores than children with typical language skills. Further, a lower than expected MBL is predictive of a lack of meaningful speech at 24 months of age.
