ABSTRACT

The present study investigated the development of second-order theory of mind and interpretive theory of mind in Korean 6-year-olds and also examined whether these two abilities are related to evidential reasoning abilities. The results showed that, overall, Korean 6-year-olds performed lower than chance level on the second-order false-belief task, suggesting it is still developing at this age. In the interpretive theory of mind task, performance was relatively good, although children still had difficulty explicitly explaining their reasons behind their choices. Individual differences in the second-order theory of mind scores showed a positive association with the differences in evidential reasoning abilities. Individual differences in interpretive theory of mind abilities also showed a positive association. These results suggest that skills that require representing and computing diverse and complex mental states develop in parallel, or perhaps the second-order theory of mind and interpretive theory of mind abilities might underlie the development of the abilities to reason about the certainty of information obtained and reported from different sources.
