Effects of minority status in the classroom on children's intergroup attitudes.

Three studies examined the effects of relative group size on the development of children's intergroup attitudes. The studies employed a novel group paradigm in which elementary school children attending a summer school program were assigned to larger (i.e., majority) or smaller (i.e., minority) novel groups in their classroom (denoted by colored tee-shirts). In each study, relative group size was situated within a different classroom context. Study 1 examined the effects of relative group size when teachers made functional use of the novel groups and were themselves members of the novel groups. Study 2 examined the effects of relative group size in the absence of functional use. Study 3 examined the effects of relative group size when the classroom environment contained implicit messages about group status. In each study, children's intergroup attitudes (e.g., trait ratings, group evaluations) were assessed following several weeks in the classroom. The effect of relative group size on in-group bias was complex, varying as a function of (a) the relative size and salience of groups, (b) the measure used to assess intergroup attitudes, (c) group status (higher or lower), and (d) children's age.
