Abstract
In deciding when to help, individuals reason about whether prosocial acts are impermissible, suberogatory, obligatory, or supererogatory. This research examined judgments and reasoning about prosocial actions at three to five years of age, when explicit moral judgments and reasoning are emerging. Three-to five-year-olds (N = 52) were interviewed about prosocial actions that varied in costs/benefits to agents/recipients, agent-recipient relationship, and recipient goal valence. Children were also interviewed about their own prosocial acts. Adults (N = 56) were interviewed for comparison. Children commonly judged prosocial actions as obligatory. Overall, children were more likely than adults to say that agents should help. Children's judgments and reasoning reflected concerns with welfare as well as agent and recipient intent. The findings indicate that 3-to 5-year-olds make distinct moral judgments about prosocial actions, and that judgments and reasoning about prosocial acts subsequently undergo major developments.
