Two experiments examined whether the correlation between advances on theory-of-mind and executive function tasks results from the tasks posing the same executive demands among 3- to 6- year-olds. Findings indicated that performance on the dimensional change card-sorting task (a measure of executive function) was correlated with performance on the false-belief prediction task and false-belief explanation task (measures of theory-of-mind). However, the correlation cannot be due to executive demands. (JPB)
