Abstract

We investigated manifestations of jealousy in preschoolers (n=32) with autism spectrum disorder (ASD) and in a group of typically developing children (n=18) matched on mental age, verbal mental age, nonverbal mental age, and mother’s education. Main results revealed explicit indices of jealousy in two thirds of the children with ASD compared with 94.5% in the typical group. In addition, different manifestations of this emotion emerged in the ASD group compared with the matched control group. Regarding mental and affective correlates of jealousy, expressions of jealousy correlated with IQ only for the children in the ASD group, and the ASD group revealed deficient emotional responsiveness (ER) capabilities. Significant correlations emerged between jealousy and ER in both the ASD and control groups. Discussion focuses on implications of these findings for understanding the core emotional deficit in autism.
