This study defines Theory-of-Mind as the ability to experience one's own mind and understand the minds of others to the extent necessary to make sense of human behaviour and the world.

Since the concept of Theory-of-Mind was first applied to people with ASD, lack of Theory-of-Mind has been used to explain their cognitive difficulties, along with social, communicative and imaginative impairments. Previous studies have tended to think of Theory-of-Mind in terms of a simple binary of deficit or credit; to exclude the voices of people with ASD; to emphasise the cognitive aspects of Theory-of-Mind over its affective aspects; and to emphasise understanding the minds of others over experiencing one's own mind. This study aims to address these issues by investigating Theory-of-Mind as subjectively experienced by students with ASD and objectively understood by their teachers. It is the first attempt in the study of Theory-of-Mind to include the voices of individuals with ASD along with the professional views of their teachers.

This study takes an interdisciplinary approach, supported by philosophy of mind and special education. A grounded theory approach and a mixed methods research design combine to build and strengthen a theory of Theory-of-Mind. For Theory-of-Mind as subjectively experienced, 20 senior secondary and post secondary school students with ASD from Republic of Korea were interviewed and student-produced documents were reviewed to draw out their inner experiences. The Korean Wechsler Adult Intelligence Scale and the Korean Vineland Social Maturity Scale were employed to assess IQ and social competence. For Theory-of-Mind as objectively understood, their teachers' beliefs regarding their students with ASD were sought through in-depth interviews, a review of teacher-produced documents and administration of a newly developed Teacher Questionnaire.

This study reports differences between Theory-of-Mind as subjectively experienced and objectively observed, and variations within the components of Theory-of-Mind. The role of imagination in Theory-of-Mind and the relationships between Theory-of-Mind Components, IQ and social competence are discussed. As a result, a Theory-of-Mind continuum model and Theory-of-Mind Typology is proposed.
