This questionnaire study examined elementary school student's knowledge of a number of gender norms as well as some moral and social norms. Participating in the study were 111 first, third, and fifth graders, the majority of whom were white, with a small number of Hispanic and Asian children. The gender roles related to children's play, hair length, occupations, and clothing. Moral norms included stealing money versus asking for it and pinching versus saying hello when meeting someone. Social norms included eating ice cream with fingers versus a spoon. The children's beliefs about the possibility of violating these norms and their attitudes about other children who violated them were also measured. Findings indicated that children displayed strong knowledge of the norms, although older children had somewhat greater knowledge of the gender norms. Beliefs about whether it was possible to violate the norms increased with age. There were few age differences in the evaluation of norm violations, but moral norm violations were seen as the most serious, followed by social, and least serious were gender role violations. There were notable differences in evaluations of various gender norms. (KB)
