How do children coordinate information about mental states with social norms?

We investigated how 3–7-year-olds weigh and coordinate information about specific mental states with social norms in the domain of contextually conventional rules. With increasing age, participants increasingly took into account an actor's mental state to predict that actor's behavior. In a criticism judgment task, 7-year-olds could assign criticism conditional on mental state, with response patterns similar to those of adults; 5-year-olds assigned criticism regardless of the actor's mental state. Three-year-olds tended not to assign criticism at all, irrespective of the actor's mental state. Results indicated that the ability to weigh and coordinate information about mental states with understanding of norms depends on age and on the particular type of judgment being made. To some extent, our results may also reflect the influence of culture and parenting.
