Children With Specific Language Impairments Perceive Speech Most Categorically When Tokens Are Natural and Meaningful.
Purpose: To examine perceptual deficits as a potential underlying cause of specific language impairments (SLI). Method: Twenty-one children with SLI (8;7-11 ;11 [years; months]) and 21 age-matched controls participated in categorical perception tasks using four series of syllables for which perceive...

Method: Twenty-one children with SLI (8;7-11 ;11 [years; months]) and 21 age-matched controls participated in categorical perception tasks using four series of syllables for which perceived syllable-initial voicing varied. Series were either words or abstract nonword syllables and either synthesized or high-quality edited natural utterances. Children identified and discriminated (a) digitally edited tokens of naturally spoken “bowl”-“pole”, (b) synthesized renditions of “bowl”-“pole”, (c) natural “ba”-“pa”, and (d) synthetic “ba”-“pa”. Results: Identification crossover locations were the same for both groups of children, but there was modestly less accuracy on unambiguous endpoints for children with SLI. Planned comparisons revealed these effects to be limited to synthesized speech. Children with SLI showed overall reduced discrimination, but these effects were limited to abstract nonword syllables. Conclusion: Overall, children with SU perceived naturally spoken real words comparably to age-matched peers but showed impaired identification and discrimination of synthetic speech and of abstract syllables. Poor performance on speech perception tasks may result from task demands and stimulus properties, not perceptual deficits.
