Executive function and children's understanding of false belief: How specific is the relation?

The present study examined developmental relations among understanding false belief, understanding "false" photographs, performance on the Dimensional Change Card Sort (DCCS), and performance on a picture-sentence verification task in 69 3-5-year-old children. Results showed that performance on the DCCS predicted performance on false belief questions even after controlling for children's age and verbal ability. However, neither performance on the picture-sentence verification task, nor performance on the "false" photograph task predicted false belief understanding. Implications of these findings are discussed in the context of suggestions that understanding false belief reflects a general understanding of representation, propositional negation, and the ability to use higher order rules.
