Why are some people relatively easily accepted in our group, and others not? How is it influenced by the quality of relations in the group? In what ways expectations towards newcomers determine the rules of ingroup membership? Those and similar questions referring to intra-, and intergroup relations have been raised for a long time in social sciences, including social psychology. However, most of the offered explanations focus on the objects involved (persons, groups), and not on the relations themselves. Our project aims at the analysis of national attitudes and their implications for intra-, and intergroup relations, with the use of Relational Models Theory (RMT, Fiske, 1991). The RMT models – communal sharing (CS), authority ranking (AR), equality matching (EM) and market pricing (MP) – determine the structure of the relations, their motivational aspect, coordinate the rules of resources exchange and distribution, social influence, work organization, and decision making. The main goal of the project is to examine how different models of intragroup relations facilitate tolerance towards newcomers, and which of those models reinforce the existing divisions. Moreover, we plan to test experimentally the relationship between the different models of intragroup relations, group identity, and tolerance towards others.
