Quantifying narrative ability in autism spectrum disorder : a computational linguistic analysis of narrative coherence . Autism is a neurodevelopmental disorder characterized by serious difficulties with the social use of language , along with impaired social functioning and ritualistic/repetitive behaviors ( American Psychiatric Association in Diagnostic and statistical manual of mental disorders : DSM-5 , 5th edn . American Psychiatric Association , Arlington , 2013 ) . While substantial heterogeneity exists in symptom expression , impairments in language discourse skills , including narrative ( or storytelling ) , are universally observed in autism ( Tager-Flusberg et al . in Handbook on autism and pervasive developmental disorders , 3rd edn . Wiley , New York , pp 335-364 , 2005 ) . This study applied a computational linguistic tool , Latent Semantic Analysis ( LSA ) , to objectively characterize narrative performance in high-functioning individuals with autism and typically-developing controls , across two different narrative contexts that differ in the interpersonal and cognitive demands placed on the narrator . Results indicated that high-functioning individuals with autism produced narratives comparable in semantic content to those produced by controls when narrating from a picture book , but produced narratives diminished in semantic quality in a more demanding narrative recall task . This pattern is similar to that detected from analyses of hand-coded picture book narratives in prior research , and extends findings to an additional narrative context that proves particularly challenging for individuals with autism . Results are discussed in terms of the utility of LSA as a quantitative , objective , and efficient measure of narrative ability .
