Autistic adults and adults with sub-clinical autistic traits differ from non-autistic adults in social-pragmatic inferencing and narrative discourse

Abstract

<div lang="en" class="abs"><p class="abs_header">Abstract</p><p>Since prior research has mostly focused on children, less is known about how autistic adults and adults with sub-clinical autistic traits interpret pragmatically complex social situations and the kind of narrative discourse they produce. 32 autistic young adults, 18 young adults with sub-clinical autistic traits and 34 non-autistic young adults participated this study. They were shown videos of social interactions which required complex pragmatic processing and were asked to freely narrate what they thought was occurring in each video. Their narratives were coded for aspects of social-pragmatic and narrative discourse. The results indicate that the autistic and sub-clinical groups differed from the comparison group in what they inferred as relevant video content. The narratives of the autistic group also differed from the comparison group in meaning, focus and emphasis on details. In addition, the comparison group produced more holistic narratives whereas the autistic and sub-clinical groups produced more atomistic narratives. Correlational findings indicated that perceptual reasoning has stronger associations with pragmatic inferencing in the autistic and sub-clinical groups than in the comparison group. This study suggests that autistic adults and adults with sub-clinical autistic traits differ from non-autistic adults in what they perceive to be relevant in their social world.</p></div>
