In this chapter, we review the sometimes-subtle traces of social psychological insights in the current sociological studies of children and youth and use this review to argue that a more explicit connection between the sociology of children and youth and sociological social psychology will advance both our understandings of this population and social psychological research. To make this case, we first discuss how children and youth are a uniquely interesting developmental stage. Then we briefly discuss core social psychological concepts relevant to children and youth’s life chances: role, self and identity, socialization, status, and emotion. Finally, we use three important topics in the studies of children and youth—peer cultures, risky behaviors, and life transitions—to illustrate how applying social psychology can deepen our understandings of children and youth’s development. By doing so, we demonstrate the inevitable and lively connection between the social lives of children and youth and social psychology. We conclude with a call for further engagement with the field of social psychology in future research on children and youth.
