  1. LVCP low verbal and cognitive performance with autism, HVCP high verbal and cognitive performance with autism, NT neurotypical. 1Original group of 22 less 4 with unsuccessful scans and 1 with excess motion. 2Original group of 20 less 1 with excess motion. 3 IQ composite is the Differential Ability Scales-II General Conceptual Ability or Wechsler Full-Scale IQ. 4Verbal scores reflect Vocabulary subtest or Verbal index scores. Two scores from LVCP group were not obtained (verbal level estimated by ADOS Module 1 for adolescent and another with overall composite score of 49). The verbal score was not obtained for one individual in the HVCP group, IQ composite score = 88). 5Verbal scores were highly correlated with overall IQ scores, r = .945, p < .001. 6Autism Diagnostic Observation Scale, Second Edition, Calibrated Severity Score (comparison score), which is from a 10-point scale, where 0 = minimal-to-no evidence of autism, 10 = high evidence of autism. For all comparisons, significant differences indicate p < .001 and no significant differences indicate p > .05
