This study addressed the impact of perceived familial and peer norms, gender, and intergroup anxiety on the relationship between the quality of inter-ethnic contact and blatant and subtle ethnic attitudes of adolescents. With regard to the main focus of the study—the moderating effect of perceived norms—familial norms had a gender-specific impact on the relationship between contact quality and subtle attitudes. Further, both familial and peer norms predicted the blatant and subtle attitudes of youth. Contact quantity had no effect, but contact quality had strong effects on both attitudes. Intergroup anxiety had direct and mediating effects on both kinds of attitudes. The results are discussed in relation to social-contextual and developmental factors affecting the formation of ethnic attitudes.
