Fig. 1: Group differences in cognitive and motor functioning.

Higher scores indicate better cognitive performance for all domains, except attention, impulsivity, and reaction time. Full Scale IQ and processing speed are reported on a standard score scale (M = 100, SD = 15), attention, impulsivity, and reaction time are reported on a t-score scale (M = 50, SD = 10), and motor is reported as a raw score. The measures used to assess the noted cognitive domains are outlined in Supplementary Table 1. ASD, autism spectrum disorder
