Many individuals with autism spectrum disorder (ASD) have atypical sensory processing and behaviors including sensory sensitivity and low registration of sensory stimuli as well as sensory seeking and avoiding behaviors. Additionally, many individuals with ASD have clinically distressing levels of anxiety. Previous research suggests that there is a link between abnormal sensory processing, anxiety, and ASD. The purpose of this study was to experimentally observe auditory sensory processing using pupillometry methods, between ASD, control, and high-anxious control groups. While a difference in tonic pupil size was observed, there were no reactivity or habituation differences between the groups. There were no significant correlations between the pupillometry measures and behavioral measures of emotional distress and anxiety. These results do not indicate a relationship between anxiety and unimodal auditory response in ASD. Implications and directions for future research are discussed.
