Abstract
This study investigated behavioral indicators of social fear in preschool boys with fragile X syndrome (FXS) with a low degree of autism spectrum disorder (ASD) symptoms (FXS-Low; n = 29), FXS with elevated ASD symptoms (FXS-High; n = 25), idiopathic ASD (iASD; n = 11), and typical development (TD; n = 36). Gaze avoidance, escape behaviors, and facial fear during a stranger approach were coded. Boys with elevated ASD symptoms displayed more avoidant gaze, looking less at the stranger and parent than those with low ASD symptoms across etiologies. The iASD group displayed more facial fear than the other groups. Results suggest etiologically distinct behavioral patterns of social fear in preschoolers with elevated ASD symptoms.
