ASD measures are from the diagnostic procedure at the Autism Center, which typically includes the following: full-scale IQ using the Wechsler Scales of Intelligence (WISC-IV) [47] or Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III) [48] (four of the five missing IQ scores reflect large gaps across the IQ subscales that prevented derivation of a final score; note that the subscale data implied average IQ for these children); Vineland Adaptive Behavior Scales (VABS) [16]; Autism Diagnosis Observation Schedule (ADOS; a semi-structured, interactive schedule designed to assess social and communicative functioning [49]; to assess autism symptom severity, we used the standardized ADOS severity score [14]); and Autism Diagnostic Interview-Revised (ADI-R; a semi-structured interview administered to parents [50]). Values of severity range between 1 and 10, with a cutoff of 3 for inclusion in ASDs. All TD participants were screened for ASD using the Social Communication Questionnaire (SCQ) [46], a 40-item parent-report questionnaire for brief screening. A dash (“–“) indicates that the test was not preformed or could not be evaluated.
