基于不确定认同与社会认同复杂性理论,通过两个实验探讨了自我不确定性与认同复杂性对群体认同的影响。实验-研究自我不确定性与群体重叠性对群体认同的影响,操作自我不确定,结果表明高自我不确定性情境下个体的群体认同感显著高于低自我不确定性情境下的群体认同感,但群体重叠性对群体认同影响不显著。实验二考察自我不确定性与群体数目对群体认同的影响,结果发现自我不确定性显著影响群体认同感,但是群体数目对群体认同没有显著影响。

英文摘要：

Based on uncertainty-identity theory and the concept of social identity complexity, we conducted two experiments to test the influence of self-uncertainty and social identity complexity on group identification. We tested the influence of self-uncertainty and the degree of overlap of identities on group identification in Experiment 1. We manipulated the self-uncertainty, the result suggested that compared with low self-uncertainty,participants＇ group identification was stronger under high self-uncertainty,but the influence of the overlap of group had no difference on group identification. Then we investigated the influence of self-uncertainty and the number of identities people had on group identity in Experiment 2. The result showed that self-uncertainty had significantly influence on the group identification, but the number of identities hadn＇t. The result of our study showed that the self-uncertainty affected the group identification.
