New research from Marcus Autism Center investigators helps to resolve a question about the reduced attention to the eyes in children with autism spectrum disorders: is it because of aversion, or lack of perception of social cues?

A new study conducted by researchers at Marcus Autism Center, Children’s Healthcare of Atlanta, and Emory University School of Medicine helps put to rest a longstanding controversy and question about children with Autism Spectrum Disorder. Eye-tracking measures developed by the group demonstrate that young children with autism do not avoid eye contact on purpose; instead, they miss the significance of social information in others’ eyes.

While reduced eye contact is a well-known symptom of autism used in early screeners and diagnostic instruments, why children with autism look less at other people’s eyes has not been known. New research, reported today in The American Journal of Psychiatry, helps answer that question.

“This is important because we’re disentangling very different understandings of autism,” said Jennifer Moriuchi, a graduate student at Emory University. “Depending on why you think children with autism are making less eye contact, you might have different approaches to treatment and different ideas about the brain basis of autism. Drug treatments and behavioral interventions are already being developed and tested on the basis of these different explanations. By clarifying which explanation is correct, we can make sure that we’re addressing the correct underlying concern.”

Two explanations for reduced eye contact have been proposed. One explanation holds that children with autism avoid eye contact because they find it stressful and negative. The other explanation holds that children with autism look less at other people’s eyes because the social cues from the eyes are not perceived as particularly meaningful or important.

The new research, conducted on the day when children were first diagnosed, shows that young children with autism do not actively avoid eye contact, and it confirms that other people’s eyes are not aversive to young children with autism. Instead, young children with autism look less at the eyes because they appear to miss the social significance of eye contact.

Together with Drs. Ami Klin and Warren Jones, Moriuchi studied how 86 two-year-old children with and without autism paid attention to other people’s eyes. Children with autism watched a series of carefully made videos. “Before each video, we flashed a small picture to capture the child’s attention, and when they looked to where the picture had been, they found that they were either looking directly at another person’s eyes or looking away from the eyes,” said Moriuchi. “When we did this repeatedly, we found that young children with autism continued to look straight at the eyes. Like their peers without autism, they didn’t look away from the eyes or try to avoid the eyes in any way.”

However, when varying levels of socially meaningful eye contact were presented, children with autism looked less at other people’s eyes than their peers without autism. “These results go against the idea that young children with autism actively avoid eye contact,” said Warren Jones. “They’re looking less at the eyes not because of an aversion to making eye contact, but because they don’t appear to understand the social significance of eye contact.”

The researchers studied eye gaze responses in young children with autism at the time of their initial diagnosis in order to have clearer evidence about the initial underlying reasons for reduced eye contact. Some adults and older children with autism have reported feeling anxious in response to eye contact. “Our results aren’t meant to contradict these personal experiences,” emphasized Jones. “For children with autism, social signals can be confusing. And as children grow up to be adults, those signals can become even more challenging to understand. This research highlights the opportunity to target the right underlying concerns as early as possible.”

“Studies like this one help advance our understanding of autism and improve the way scientists and clinicians develop new treatments,” said Lisa Gilotty, Chief of the Research Program on Autism Spectrum Disorders at the National Institute of Mental Health, one of the agencies that funded the study. Additional support was given by the Autism Science Foundation, the Marcus Foundation, the Whitehead Foundation, and the Georgia Research Alliance.
