  1. Note. Mean age, gender, autism-spectrum quotient (AQ), 20-item Toronto Alexithymia Scale (TAS-20), (state (SA) and trait (TA)) anxiety scores, and IQ scores for the autism spectrum disorder (ASD) group and the matched neurotypical controls. Autism Diagnostic Observational Schedule (ADOS) score and classification details for the ASD group: A higher score represents greater autism severity. Standard deviations are shown in brackets. The IQ score for one control participant was unavailable and therefore not reflected in the group mean
