Children often encounter events that bear on their moral and other evaluations, such as physical aggression and material disorder. Children's perceptions and evaluations are decisive for how they respond to and learn from these everyday events. Using a new method for investigating the development of social perceptions and evaluations, researchers interviewed 3- to 6-year-olds about naturalistic video recordings of "harm, disorder", and "joint play" events. Children distinguished between the situations in the perceived intent of the protagonists, evaluations, justifications, and what they thought the protagonist should do after. Age differences suggested that perceiving and evaluating simple everyday situations was challenging for younger children. This research highlights the importance of studying children's everyday social perceptions and evaluations and validates a new paradigm for doing so.
