Social psychology and research on intergroup relations has long been dominated by an approach that favoured comparisons between one ingroup and one outgroup, ignoring the possible membership of the same person in multiple social categories. Research on multiple categorical membership and intersectionality is so far absent in Czech and Slovak social psychology. The main objective of this review is to present the theories, approaches and models through which international social psychologists have approached the investigation of the aforementioned concepts. The paper discusses their strengths and weaknesses and then formulates recommendations for further research in this area, with particular emphasis on intergroup relations in the Slovak context.
