Young adults with High Functioning Autism and a matched comparison group told personal narratives using a standard conversational procedure. Longest narratives were determined (i.e., number of propositions included) and scored using an analysis that looks at the organization of a narrative around a highpoint. The group with Autism Spectrum Disorder produced narratives with significantly poorer HP macrostructure and introduced proportionately fewer propositions with conjunctions. Such impairments in the ability to make sense of personal experiences both reflect and contribute to difficulty in social-emotional functioning.
