Investigating the Grammatical and Pragmatic Origins of Wh-Questions in Children with Autism Spectrum Disorders.

Compared to typically developing children, children with autism (ASD) show delayed production of wh-questions. It is currently controversial the degree to which such deficits derive from social-pragmatic requirements and/or because these are complex grammatical structures. The current study employed the intermodal preferential looking (IPL) paradigm, which reduces social-pragmatic demands.

"Didn't I just say that?" Comparing parent report and spontaneous speech as indicators of grammatical development.

Background: The Vineland Adaptive Behavior Scales use parental report to examine communication and social skills in children with typical and atypical development, and exhibit high reliability when compared against overall direct testing. However, findings are mixed comparing Vineland communication/language scores with experimenter-administered tests of language.

Methods: The current study breaks new ground in comparing Vineland reports with direct observation of children's speech by (a) individual items and (b) level of child functioning, focusing on usage of wh-questions, verb tenses, negation, pronouns and noun-verb combinations.
