TL;DRAbstract

This research extends prior work on von Grünau and Anston's (1995) stare-in-the-crowd effect whereby direct gaze relative to averted gaze is detected faster in visual search tasks. No research has yet explicitly investigated the effect of varying the identity of the facial stimuli presented to participants. To enhance this paradigm's ecological validity, the present study varied facial identity over three experiments. Sixty-eight non-clinical adults detected front-facing target faces with both direct and averted gaze from among variable array sizes. Two groups were formed according to high or low scores on the Autism Quotient (AQ) and their reaction times were compared in each experiment. Instead of the expected advantage for direct-gaze detection, between-subjects and within-trials manipulations of facial identity produced a tendency for participants to detect averted gaze more quickly. However, AQ score moderated this tendency: Low-AQ participants detected direct gaze faster, while H
