Abstract
While it is widely recognized that autism undercuts conversational ability, there has been little systematic examination of the involvement of children with autism in informal conversational interaction. This study compares the behaviour of 15 children with autism and 15 children with developmental delays matched on language ability within the context of a semi-structured conversation. Children with autism more often failed to respond to questions and comments, less often offered new, relevant contributions, and produced fewer narratives of personal experience. In contrast to prior research findings, groups did not differ with respect to use of gesture: several children with autism enhanced their communication through dramatization and pointing. Discussion focuses on the nature of pragmatic impairment in autism; factors underlying the development of conversational ability, including theory of mind; and practices that may promote communicative competence.
