Ethnic categorization of immigrants:The role of prejudice, perceived acculturation strategies and group size

People usually perceive immigrants from different national origins as similar to each other, and thus as belonging to a limited number of ethnic out-groups [Sporer, S. L. (2001a). Recognizing faces of other ethnic groups: An integration of theories. Psychology, Public and Law, 7, 36–97, Sporer, S. L. (2001b). The cross-race effect: Beyond recognition of faces in the laboratory. Psychology, Public Policy and Law, 7, 170–200.]. In this study, we examine how host nationals (i.e., Italians) categorize immigrants and how prejudice and perceived acculturation strategies influence this process. In our research, photographs of male faces of members of 16 immigrant groups were shown to the participants (N ¼ 305). They were asked to identify the national origin of each person on the photographs. In line with the expected over-inclusion into more numerous and more devalued outgroups, the researchers found that (a) participants who perceived Albanians or Moroccans to be the most numerous, were most likely to categorize immigrants as belonging to these groups; and (b) this over-inclusion effect was most pronounced when participants were prejudiced toward these groups and when they perceived them as wanting to maintain their cultures of origin
