Age-related changes in children's and adults' explanations of interpersonal actions

We investigated the content of children's and adults' explanations of interpersonal actions. Participants were 5-, 7-, and 9-year-old children, as well as adults, who were presented with 8 stories containing either prosocial or antisocial target actions, and asked to explain why each actor performed that action. In half of the stories, an interpersonal event preceded the action. Children and adults provided situational and mental-state explanations, but mental-state explanations were especially common for antisocial actions not preceded by an interpersonal event. With increasing age, participants explained prosocial actions by referring to the actor's goals, but referred to the actor's emotions and beliefs to explain antisocial actions. Finally, adults were most likely to mention psychological goals. These results suggest that (a) elementary school children provide a variety of explanations for interpersonal events; (b) children use different types of explanations flexibly, depending on the context and nature of the target action; (c) the frequency of different types of explanations for interpersonal actions changes during childhood; and (d) between middle childhood and adulthood, the recognition of psychological goals increases greatly.
