Popis: 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.
