Drawing impossible entities: a measure of the imagination in children with autism, children with learning disabilities, and normal 4-year-olds.

Contemporary findings suggest that the imagination of autistic children is not as limited as was once thought. In contrast, Scott and Baron-Cohen (1996) claim that children with autism are unable to draw pictures of impossible entities. An experiment showed that children with autism, children with moderate learning disabilities, and normal 4-year-olds were equally successful at identifying real and impossible pictures and at completing pictures to make them look either real or impossible. The previously reported inability to draw "impossible" pictures is unlikely to reflect an imaginative deficit and may instead result from a misunderstanding of the task or limitations in the executive abilities required to plan and draw an unusual picture for the first time.
