Theory of mind: is training contagious?

In this study, preschool children were successfully trained in theory of mind tasks, namely false belief inference and appearance–reality distinction. Results show that both types of training had a direct effect, as measured by the improvement of performance on the FB and AR delayed post-tests. Both types of training also had an indirect effect, as measured by transfer of the benefits of the training to the task that was not in the training. Finally, both types of training were effective even when the children were trained in a task they had already mastered.
