Previous research demonstrates an uneven pattern of cognitive abilities in children with autism spectrum disorders (ASDs). This study examined whether this uneven pattern exists within the nonverbal domain in young children. We hypothesized relative strengths in perceptual abilities and weaknesses in nonverbal conceptual abilities in preschoolers with ASDs compared to groups with non-autism developmental delays and typical development. Profiles were examined using the Leiter International Performance Scale-Revised. The ASD group displayed clear relative strengths in visuospatial disembedding and detail-focused processing, with relative weaknesses in abstraction and concept formation. This contrasted with patterns of roughly equivalent abilities in both comparison groups. These findings have implications for subsequent development and may represent key features of the cognitive profile of autism.
