In the past decades, an important area of research into autism psychology has been focused on explaining the theory of mind in autistic children.

A thesis that children and persons with autism have significant difficulties in the theory of mind area has been proven in many tests, the first of which was the one with Sally and Ann, reported 1985 (Simon Baron-Cohen, Alain Leslie and Uta Frith), subsequently confirmed by many other similar tests. Children with autism solved the test with much lower scores than typical children of the same mental age and those with Down's syndrome. Although the theory of mind explains a great part of symptoms in autism (social interactions, communication and imaginative play), it is not the only cognitive deficit. The other two deficits in cognitive processes are executive function and central coherence, which may explain other symptoms, primarily repetitive behavior and unusual perception. Increasing the level of ability in the theory of mind area in autistic children would have favorable impact on their social cognition.
