Résumé :	Background Social interaction at its core entails allocating attention to relevant stimuli. As such, the perception of change requires attention, but studies have suggested that the social impairment in people with autism spectrum disorder (ASD) occurs at the attentual level of "on-line" social cognition. Method Forty-four young adults—22 with autism spectrum disorder (ASD) and 22 with typical development (TD)—participated in two experiments. The first used a change blindness (CB) paradigm where attention was investigated through the detection of changed items with central and marginal levels of interest when viewing images of everyday scenarios. Eye-tracking was used to compare response times, first fixations and total fixation time on changes. The second used social films with eye tracking of gaze fixations. Results Participants with ASD were slower in response time and first fixation than were participants with TD. Participants with TD showed longer fixation on items with marginal (compared to central) levels of interest. The social-film experiment showed that participants with ASD were slower to orient their gazes towards the characters’ faces and looked at speaking characters for less time than did the group with TD. This result correlates with less use of mental verbs in their narratives and less time spent looking at marginal items in the CB experiment. Conclusions Results suggest reduced processing speed in young adults with ASD, which is associated with enhanced processing of local details. Clinically, these results imply that teaching strategies (e.g., cognitive cues) to process social context efficiently could benefit individuals with ASD.
