Research suggests that discrepant cognitive abilities are more common in children with autism spectrum disorder (ASD) and may indicate an important ASD endophenotype. The current study examined the frequency of IQ discrepancy profiles (nonverbal IQ greater than verbal IQ [NVIQ greater than VIQ], verbal IQ greater than nonverbal IQ [VIQ greater than NVIQ], and no split) and the relationship of gender, age, and ASD symptomatology to IQ discrepancy profile in a large sample of children with ASD. The NVIQ greater than VIQ profile occurred at a higher frequency than expected, had more young males, and showed more autism symptoms than the other groups. Results suggest that the NVIQ greater than VIQ profile may be less likely to represent a subtype of ASD, but rather a common developmental pathway for children with ASD and other disorders.
