中文摘要：

主观群体动力学模型（subjective group dynamics,SGD）探讨群际背景中个体的群体评价与群体成员评价的关系,针对群际偏见、分化评估和分化接纳意识（awareness of differential inclusion,ADI）三个核心变量间的关系及其影响因素,提出并验证了一系列理论假设。SGD的理论基础包括社会认同理论、复杂性-极端性假设和态度极化模型、＂白乌鸦效应＂和个体对人知觉的发展。SGD模型的研究结果深化了群内偏好研究,支持了社会领域理论,并从群体机制角度为同伴拒斥研究提供了新思路,解释了群体同质性效应并修正了认知发展理论。该领域的发展需要从跨文化检验模型、完善模型结构、研究它与其他变量的关系等方面进行进一步探索。

英文摘要：

The subjective group dynamics model（SGD） explores the relation between evaluations of groups and group members in an intergroup context. It proposes and tests a series of theoretical hypotheses about the relations among intergroup bias,differential evaluation and awareness of differential inclusion which are the three core variables and other related factors. SGD is based on theories such as social identity theory,the complexity-extremity hypothesis and the attitude polarization model,the black sheep effect and the development of person perception. This model deepens our understanding of the ingroup favoritism effect,gives support to social cognitive domain theory,and opens a new path to the research of peer rejection from the perspective of group processes,and it also explains the group homogeneity effect and modifies the cognitive developmental theory. Further exploration is needed on topics such as testing the model in different cultural contexts,improving its structure,and studying its relations with other related variables.
