Explaining Variance in Social Symptoms of Children with Autism Spectrum Disorder.

Abstract

The social symptoms of autism spectrum disorder are likely influenced by multiple psychological processes, yet most previous studies have focused on a single social domain. In school-aged autistic children (n = 49), we compared the amount of variance in social symptoms uniquely explained by theory of mind (ToM), biological motion perception, empathy, social reward, and social anxiety. Parent-reported emotional contagion-the aspect of empathy in which one shares another's emotion-emerged as the most important predictor, explaining 11-14% of the variance in social symptoms, with higher levels of emotional contagion predicting lower social symptom severity. Our findings highlight the role of mutual emotional experiences in social-interactive success, as well as the limitations of standard measures of ToM and social processing in general.
