ABSTRACT

Much of our everyday cognition is social. We allocate substantial intellectual resources to predicting and interpreting human action and interaction in terms of underlying mental states. The acquisition of a ``theory of mind'' (ToM) is thus a cornerstone developmental achievement. Moreover, ToM de®cits have been increasingly linked to clinical disorders such as autism (Baron-Cohen, Tager-Flusberg, & Cohen, 2000) and schizophrenia (Langdon, 2005). Hence, it is vital to determine when such a theory is acquired, what governs its emergence and expression, how it changes with development, and what disrupts its functioning.
