"John thinks that Mary feels. . ." False belief in children across affective and physical domains

Children aged 5-8 years (N = 64) were given 3 first- and 3 second-order tasks testing their ability to represent false beliefs about physical facts, positive emotions, and negative emotions. The children were also asked to justify their responses to the test questions. Older children were more successful than younger children at both answering the test questions correctly and justifying their responses. On the first-order problems, performance was better on the physical fact task than on the emotions tasks; the reverse was true for the second-order problems. Children primarily used situational explanations to explain correct judgments on the physical problems, whereas mentalistic explanations were more common than situational explanations on 3 of the 4 emotions tasks. The results extend knowledge of false belief beyond the simple forms studied at the preschool level.
