A broad assessment of theory of mind in adolescence: The complexity of mindreading

• We examined the Theory of Mind (ToM) of 80 preadolescents and adolescents.
• We tested 1st vs. 2nd order, 1st vs. 3rd person.
• We tested egocentric vs. allocentric perspective.
• Participants will perform better at first-person than at third-person.
• Girls will perform systematically better than boys.

The aim of this research was to provide an articulated assessment of several different ToM components, namely first- vs. third-person, egocentric vs. allocentric, and first- vs. second-order ToM, in preadolescence and adolescence. Our expectations for the sample of 80 juveniles that participated in the research were that: (1) ToM abilities would improve with age; (2) participants would perform better at first-person than at third-person tasks; (3) participants would perform better at first-order than at second-order tasks; (4) girls will perform systematically better than boys. We also explored possible differences in performance (5) in the allocentric vs. the egocentric perspectives as well as (6) in the comprehension of different types of mental states, namely desires, beliefs and positive and negative emotions. Overall our expectations were confirmed. Our data confirmed that all ToM aspects we investigated keep maturing during preadolescence and adolescence.
