Attention to live eye contact in adolescents with autism spectrum disorder.
Live eye contact triggers typical heart-rate orienting in autistic teens, so real faces—not photos—should be used when assessing social attention.
01Research in Context
What this study did
Kikuchi et al. (2022) watched autistic and typical teens during real face-to-face eye contact. They measured heart-rate slowdown, a quiet sign the brain is locking on.
The team used live video chat, not still photos. They wanted to know if autistic teens orient to human eyes the same way other teens do.
What they found
The autistic teens’ hearts slowed the same amount as typical peers when eyes met. This means their first-step attention to live gaze is intact.
Static pictures had missed this skill in earlier work. Real faces told a different story.
How this fits with other research
Walley et al. (2005) saw no special orienting to eye-direction cues in autistic adults. The new study flips that result, but the gap makes sense: adults used arrow-like gaze symbols; teens here saw a live partner. Method and age changed the outcome.
Kleinert et al. (2007) already warned that moving social scenes reveal gaze problems that still photos hide. Yukiko’s team extends that idea into live conversation and adds a heart-rate marker.
Laposa et al. (2017) showed conversation boosts eye contact in younger kids. The teen heart-rate data now line up: when the social set-up feels real, attention looks more typical across ages.
Why it matters
If you test social attention with only still pictures, you may underestimate your client’s skill. Try short live video chats or in-person eye contact trials and watch for calm body signs like slower breathing or a relaxed face. These real moments can go into your assessment report as evidence of intact orienting, helping you build goals around maintaining—rather than teaching—initial joint attention.

03Original abstract
A number of studies have reported diminished attention to the eyes in individuals with autism spectrum disorder (ASD). These studies predominantly used static images of faces as stimuli. Recent studies, however, have shown enhanced response to eye contact in typically developing (TD) individuals when they observe a person in a live interaction. We investigated physiological orienting to perceived eye contact in adolescents with ASD and TD adolescents when they observed a person in live interaction or viewed a photograph of the same person's face. We measured heart rate (HR) deceleration as an index of attentional orienting. Adolescents with ASD, as well as TD adolescents, showed significant HR deceleration for the direct gaze compared to an averted gaze in the live condition, but not in the photographic condition. The results suggest an intact response to perceived eye contact in individuals with ASD during a live face-to-face interaction. LAY SUMMARY: Individuals with autism spectrum disorder (ASD) have a different eye gaze pattern when observing photographic faces. However, little is known about how individuals with ASD process a real person's face. We measured heart rate (HR) and found that adolescents with ASD showed the typical decline in HR when they made eye contact with a real person, which suggests that both groups of individuals directed their attention to eye contact in a live face-to-face interaction.
