Perceptual perspective-taking and seriation abilities in high-functioning children with autism

This study compared a group of 18 high-functioning children with autism (9–16 years of age) and a group of 14 normally developing children (9–14 years of age) on their abilities to take the perceptual perspective of someone else and to seriate objects based on length, size, weight, and color. Results indicated that the high-functioning children with autism were as able as the normally developing children to seriate the various objects. In contrast, significant differences emerged on the perceptual perspective-taking tasks with the high-functioning children with autism as a group performing less well than the normally developing children. However, the majority of autistic children showed good perspective-taking ability. The implications of these results to our understanding of autism are discussed.
