Evaluating the Theory-of-Mind Hypothesis of Autism

ABSTRACT— Two decades ago, the theory-of-mind hypothesis of autism was introduced by Baron-Cohen and his colleagues; this theory provided a unified cognitive explanation for the key social and communication symptoms in that disorder. I evaluate the theory-of-mind hypothesis in light of studies that have addressed several key questions: Do children with autism develop theory-of-mind concepts? How can we explain why some children with autism pass theory-of-mind tasks? Do deficits in theory of mind account for the major impairments that characterize autistic disorder? Current research supports the view that autism involves delays and deficits not only in the development of a theory of mind but also in additional aspects of social-affective information processing that extend beyond the traditional boundaries of theory of mind.
