中文摘要：

群体情绪凝聚是指,随着时间推移,群体中群体成员的情绪体验趋于一致的现象。以往研究主要从群体规范、群体身份诱发、情绪渲染,以及情绪比较来对群体情绪凝聚现象进行解释。此外,研究表明,群体成员的个人特质、群体特质（例如群体成员间的关系、情绪表达倾向的组合、共同经历等）等因素均可能影响群体情绪的凝聚。未来的研究可以进一步探讨（1）情绪比较和情绪渲染各自在群体情绪凝聚中的作用;（2）不同规模,特别是大规模群体中的情绪凝聚;（3）不同强度及类型（基本情绪、社会性情绪）情绪的凝聚;（4）结合群体情绪凝聚和群体情绪强度变化两个方面系统地对群体情绪进行考察。

英文摘要：

Group emotional convergence refers to the phenomenon that group members come to consistent emotional experience in a group over the time. In the previous studies, group emotional convergence may be attributed to the following reasons： First, group norms dramatically allow group members to experience the consistent emotion; second, group members would consider questions from the perspective of a group rather than their own while group identity is induced, therefore experiencing consistent emotions; third, individuals in a group would simulate others＇ emotion automatically; and finally, group members may compare their own emotion with others＇ in the fuzzy situation to adjust their own emotion, trying to be consistent especially when being inconsistent with others. Such factors as individual traits, group characteristics, group tasks and initial emotional states are likely to affect the group emotional convergence. This research suggests that future research is needed to investigate the boundary conditions of the above-mentioned four mechanisms. It is also needed to explore the group emotional convergence in groups with larger size and in situations where members share strong emotional events.
