Face processing in children with autism

Recent eye tracking studies of face processing have produced differing accounts of how and whether children with autism differ from their typically developing peers. The two groups' gaze patterns appear to differ for dynamic videos of social scenes, but not for static photos of isolated individuals. The present study replicated and extended previous research by comparing the gaze patterns of individuals with and without autism for four types of stimuli: social dynamic, social static, isolated dynamic, and isolated static. Participants with autism differed from their typically developing peers only for social-dynamic stimuli; fixation durations were decreased for eye regions and increased for body regions. Further, these fixation durations predicted scores on a measure of social responsiveness. These findings reconcile differences in previous reports by identifying the specific social and dynamic task components associated with autism-related face processing impairments.
