A meta-analysis was performed to examine differences in IQ profiles between individuals with Asperger’s disorder (AspD) and high-functioning autism (HFA). Fifty-two studies were included for this study. The results showed that (a) individuals with AspD had significantly higher full-scale IQ, verbal IQ (VIQ), and performance IQ (PIQ) than did individuals with HFA; (b) individuals with AspD had significantly higher VIQ than PIQ; and (c) VIQ was similar to PIQ in individuals with HFA. These findings seem to suggest that AspD and HFA are two different subtypes of Autism. The implications of the present findings to DSM-5 Autism Spectrum Disorder are discussed.
