Describe the relationship between social psychology and developmental psychology.

Developmental psychology is the study of how people change across their lives, from conception and birth to old age and death. In practice, most developmental psychologists study children. Developmental psychology has borrowed much from social psychology and built on it, such as by studying at what age children begin to show various patterns of social behavior. Developmental psychology also has often borrowed social psychology theories. Until now, social psychology has not taken much from developmental psychology, though this may be changing. Social psychologists interested in self-regulation, emotion, gender differences, moral reasoning, prosocial behavior, and antisocial behavior sometimes look to the research on child development to see how these patterns get started.
