One mechanism is reduced attention to the eyes, but the reasons behind this atypical behavior remain debated. This study investigated whether reduced attention to the eyes associated with autistic traits stems from aversion or indifference. One hundred and twenty-seven adolescents and young adults with varying levels of autistic traits completed a gaze direction task while their eye position and pupil size were recorded. Higher levels of autistic traits were associated with reduced dwell time on the eye region after, but not before, gaze direction judgments, indicating reduced attention when it was not task-relevant. Autistic traits were associated with more frequent exits and re-entries from/to the eye region after judgments, indicating less stable social engagement. Additionally, autistic traits were not associated with enlarged pupillary responses, indicating no heightened arousal expected with aversion. These findings demonstrate reduced sustained engagement with the eyes among individuals with higher levels of autistic traits, consistent with indifference rather than aversion. The temporal specificity—emerging primarily after task completion—helps reconcile contradictory literature findings. Results suggest interventions should focus on enhancing sustained social engagement rather than addressing aversion.
