Disentangling syntactic, semantic and pragmatic impairments in ASD: Elicited production of passives

Abstract

Children with ASD and an IQ-matched control group of typically developing (TD) children completed an elicited-production task which encouraged the production of reversible passive sentences (e.g., Bob was hit by Wendy). Although the two groups showed similar levels of correct production, the ASD group produced a significantly greater number of reversal errors (e.g., Wendy was hit by Bob, when, in fact Wendy hit Bob) than the TD group (who, when they did not produce correct passives, instead generally produced semantically appropriate actives; e.g., Wendy hit Bob). These findings suggest that the more formal elements of syntax are spared relative to more semantic/pragmatic/narrative aspects (e.g., manipulating thematic roles) in at least high-functioning children with ASD.
