The purpose of this study was threefold. It attempted to develop an attitude scale to measure prejudice in elementary school-aged children. It then compared these children's self perceptions with the perceptions of members of other race-sex groups using the Scale of Children's Attitudes toward Race and Gender. In addition, it investigated differential teacher/student interactions as a potential source of influence on children's attitudes. Approximately 250 third and fourth grade students participated in the study. Modifications made to the Scale of Children's Attitudes toward Race and Gender were found to have satisfactory psychometric properties. Analyses of the children's attitude data support an interaction effect between race and sex with regard to children's prejudice. The study did not support a link between teacher differential treatment of and children's attitudes toward out-groups. Several possibilities are given for the results. (Contains 23 references.) (JDM)
