Fostering theory of mind development. Short- and medium-term effects of training false belief understanding / Favorecer el desarrollo de la teoría de la mente. Efectos a corto y medio plazo de un entrenamiento en comprensión de la falsa creencia

This study examines the temporal effect of different trainings designed to favour the development of false belief understanding. A sample of 78 pre-school children aged between three years, five months and three years, 11 months was divided into three training conditions. After three training sessions, they were immediately evaluated in post-test 1 and again a month and a half later in post-test 2. The results showed that the efficiency of the training conditions depended both on the type of linguistic communication and on the use of deceptive objects. Also, the effect of the training was maintained for at least a month and a half after post-test 1 and it was transferred from the trained task to other false belief tasks. The results are commented according to the possibility of using language-based trainings to foster children’s theory of mind understanding in educational contexts.
