Typical Emotion Processing for Cartoon but not for Real Faces in Children with Autistic Spectrum Disorders

摘要

This study evaluated whether atypical face processing in autism extends from human to cartoon faces for which they show a greater interest. Twenty children with autistic spectrum disorders (ASD) were compared to two groups of typically developing children, matched on chronological and mental age. They processed the emotional expressions of real faces, human cartoon and non-human cartoon faces. Children with ASD were as capable as controls in processing emotional expressions, but strategies differed according to the type of face. Controls relied on a configural strategy with all faces. By contrast, ASD children exploited this typical configural strategy with cartoons but used a local strategy with real faces. This atypical visual processing style is discussed in the context of face expertise.
