Abstract
Autism and social anxiety (SA) share behavioral features like reduced eye contact, variable social attention, and differences in social interactions. However, the impact of the co-occurrence of these conditions (e.g., autism with co-occurring SA) on social attention remains unknown. Therefore, we evaluated whether the degree of SA characteristics in autistic youth modulated (e.g., amplified or lessened) a core hallmark feature of autism: social attention, or looking at faces. Fifty-four autistic and 35 non-autistic children and adolescents completed a gaze-contingent eye-tracking (ET) paradigm, in which faces dynamically expressed happy or fearful expressions contingent on participant eye contact. SA characteristics were assessed via standardized self- and parent-report measures. Social attention was measured by calculating the average percent looking time at the face and eye regions of each emotional expression. Autistic participants looked less at faces than non-autistic participants, and higher self-report SA was associated with less looking at eyes in both autistic and non-autistic participants. SA features affect social attention similarly in autistic and non-autistic youth, highlighting the importance of considering co-occurring psychiatric characteristics when assessing social attention and eye contact in autistic individuals.
