Study offers clues about eye avoidance in ASD

This artilce also appeared in the 2017, volume 3 issue of ARI's Autism Research Review International newsletter.

New research indicates that individuals with autism spectrum disorders (ASD) avoid eye contact not because they lack interest in interacting socially, but because making eye contact causes them to experience unpleasant arousal in the brain’s subcortical system.
Hadjikhani says, “The findings demonstrate that, contrary to what has been thought, the apparent lack of interpersonal interest among people with autism is not due to a lack of concern. Rather, our results show that this behavior is a way to decrease an unpleasant excessive arousal stemming from overactivation in a particular part of the brain.”
Based on the study’s findings, Hadjikhani says that forcing individuals with autism to focus on other people’s eyes may be misguided. Instead, she says, “An approach involving slow habituation to eye contact may help them overcome this overreaction and be able to handle eye contact in the long run, thereby avoiding the cascading effects that this eye-avoidance has on the development of the social brain.”
