Previous research has shown that children's intergroup similarity judgements are based not only on ethnicity but also on other dimensions such as sports interest. The present research investigates the role of personality in perceived similarity between ingroup children and refugee outgroup children. A study was conducted among 9- to 12-year-old children (N = 124) at two elementary schools in the Netherlands. It was predicted and found that children take into account ethnicity as well as personality (whether a child is introverted or extraverted) when judging similarity of ingroup (Dutch) and outgroup (refugee) children. Furthermore, we predicted and found that greater perceived similarity between Dutch children and refugee children was associated with more positive attitudes towards refugee children. Finally, children felt lower levels of anxiety towards an extraverted compared to an introverted refugee child. Lower anxiety, in turn, was associated with more positive attitudes towards refugee children. Theoretical and practical implications are discussed. Statement of contribution What is already known? McGlothlin et al. (2005, British Journal of Developmental Psychology, 23, 227) found that similarity ratings are based not only on ethnicity but also on sports interest. Studies among adults show that extraversion is negatively related to anxiety and positively to cross-group friendships. What does this study add? The present study shows that children also base similarity ratings on the personality trait extraversion. Higher similarity between self/ingroup and refugee children is related to positive outgroup attitudes. This study shows that extraverted children feel less anxiety to an extraverted refugee child. Lower anxiety in children is related to more positive attitudes to refugee children in general. © 2019 The Authors.
