Using an experimental design, native majority group children (8–13 years, N = 842) evaluated acculturation strategies (assimilation, integration, and separation) adopted by immigrant and emigrant peers. There were medium to large effects of the perceived acculturation strategies on children's peer evaluations. Overall, assimilation was valued most, followed by integration and separation. These effects were in part mediated by perceived national belonging. In addition, the effects were stronger for lower status compared to higher status immigrant groups, and for children with higher compared to lower national identification. For emigrants, separation was valued most, followed by integration and assimilation. This indicates that the intergroup processes rather than migration per se are important for children's acculturation perceptions and evaluations.
