In this study, intergroup bias is investigated among Dutch and Turkish children (10 -13 years of age) living in the Netherlands. Children indicated their general attitudinal orientations towards boys and girls as well as towards Dutch and Turkish contemporaries. The role of social context was examined in terms of cultural and status differences between ethnic and gender categories, and also in terms of the school situation. Compared to Dutch children, the Turkish children showed less ethnic bias but more gender bias. In addition, boys showed more ethnic bias than girls, with girls indicating more gender bias. Furthermore, Turkish children had higher ethnic identification than did Dutch children, and girls had higher gender identification than boys. Key words: gender bias; group bias; interethnic Intergroup bias about gender and ethnicity are commonly found among children. In general, children have a more positive attitude towards their own gender and towards their ethnic in-group as compared to out-groups (see for reviews Milner, 1983;Aboud, 1988;Maccoby, 1988;Brown, 1995;Fishbein, 1996). Theoretically, most of the research has used cognitive development theory as a theoretical framework for examining these attitudes. These theories have extended Piaget's and Kohlberg's constructivist work on intellectual and moral development to the study of intergroup attitudes. For instance, Aboud (1988) uses a Piagetian framework for explaining the development of prejudice in children. An age-related progression in the ability to perceive and interpret ethnic stimuli and interethnic behaviours is assumed (Doyle and Aboud, 1995). Stereotyping and intergroup attitudes are seen as information-processing errors
