The article by L. Rowell Huesmann and Nancy G. Guerra explores the relationship between children's normative beliefs about aggression and their aggressive behavior. Normative beliefs are self-regulating beliefs about the appropriateness of social behaviors. The authors revised a scale to assess these beliefs in elementary school children and found that it was reliable and valid. They investigated the longitudinal relationship between normative beliefs about aggression and aggressive behavior in a large sample of children from poor urban neighborhoods. The results showed that children's approval of aggression increased as they grew older, and this increase was correlated with an increase in aggressive behavior. Importantly, individual differences in aggressive behavior predicted subsequent differences in normative beliefs in younger children, while individual differences in normative beliefs predicted subsequent aggressive behavior in older children. The study highlights the importance of early socialization processes in shaping children's normative beliefs about aggression and their subsequent behavior.The article by L.
