Constructing fictional stories: a study of story narratives by children with autistic spectrum disorder.

Children with autistic spectrum disorder (ASD) are reported to have difficulties with narrative language but little is known about how this affects their production of fictional stories. In this study, we aimed to establish whether fictional narratives of children with ASD differed from those of typically developing children and if performance was commensurate with levels of oral language. Fictional stories produced by 27 high functioning children with ASD, aged 11-14 yrs, were compared with those of language and age matched groups of typically developing children. Differences were found between the children with ASD and comparison groups in structural, evaluative and global features of their stories indicating specific difficulties with this form of narrative. Stories of the ASD group were shorter and contained fewer causal statements than those of both comparison groups and sentences were less grammatically complex than those of the age match but not the language match group. In global measures, the stories of the ASD group were impoverished relative to both comparison groups. The results are discussed in relation to cognitive theories of autism and language development.
