We examined the differences between majority and minority children (i.e., group membership) on racial categorization and perceived cultural distance, among 4‐ to 6‐year‐old children, in low diversified schools. We used a spontaneous social categorization task using pictures of children from three different racial groups broadly represented in France (Europeans, Black‐, and North‐Africans), and an evaluation of the perceived cultural distance between participants' in‐group and the racial group represented in the picture, adapted to children and based on three factors (language, eating habits, and music). Results revealed an effect of age on racial categorization: the older the children, the more successful they are in this task. They showed a significant effect of the racial group represented in the photos on perceived cultural distance: members of minority groups (i.e., Black‐ and North‐Africans) were evaluated as more different compared to those of the majority group on each of the factors. Finally, we got an interaction between participants' in‐group and the racial group represented in the pictures, for the language factor: members of the majority group perceived as more different photographs representing minorities peers than those representing majority peers, while participants belonging to minority groups perceived no differences between photographs, according to the racial criteria.

Recent research has extensively investigated how the current COVID-19 pandemic can affect intergroup relations. Much less is known about the impact of COVID-19 on economic and trade decisions. Could the intergroup effects of this pandemic shape support for international economic policies? The aim of this study was to examine the support for restrictive economic policies towards countries with very high levels of COVID-19 contamination (China and Italy) during the first lockdown period (March - April 2020). The survey was conducted in Romania (N = 669) and included measures of COVID-19 vulnerability, prejudice, and support for economic restrictive policy (e.g., to reduce international trade; to set higher taxes). Results showed that higher support for restrictive policies toward China was associated with greater perceived vulnerability to COVID-19 and this link was partially mediated by prejudice toward China. In contrast, support for economic restrictive policies toward Italy was greater when perceived vulnerability to COVID-19 was high, but this relationship between variables was not explained by negative attitudes towards Italy. Practical and theoretical implications are discussed.

The aim of this review was to examine the effect of social and numerical group size on racial categorization and intergroup relations in children. We first described the development of racial categorization and the factors that increase the saliency of the race criterion in different contexts. Then, we examine the role of social status in intergroups relations and show that low status children express lower ingroup favoritism compared to their peers from high status groups. Few studies investigated the role of ingroup size on intergroup biases. Here, we look at this numerical variable through the proportion of children of different racial groups in the school environment. The results show that homogeneous environments contribute to the decrease of bias and negative attitudes. We discuss how identifying specific and interactive effects of the social and numerical group size would allow us to implement early and efficient intervention programs.
