A basic issue reflecting precisely these two perspectives is that of the formation of the social psychology mechanism of individual-group relations, namely the formation of the concept of ＂us＂ in Chinese society and culture, as well as the possibility and conditions for the transformation of this mechanism. Exploring this issue will not only help us to understand social cohesion and the logic of group behavior and to discuss the relationship between the state and the individual, society and the individual, and the category and the individual; it will also help cultivate social psychology resources and support systems at a time of social transition, and thus promote social cooperation.. Unlike previous analytical studies that focused on a unitary mechanism, this study uses the discussion of two cases to put forward a new framework for analysis： that is, the Chinese concept of ＂us＂ comes into being through the mingling of ＂guanxilization＂ and ＂categorization＂ under the influence of social context priming, value orientation and other factors.展开更多
