| In reality,individuals may have multiple social identities at the same time,and the complex group nature of individuals’ multiple social identities will have different effects on the cooperation between groups.Based on the stability of the complexity of social identity,individuals face different payoff structures(collective incentive maximization game-cig and equal outcome game-eog),which have an impact on the participants and then affect inter-group cooperation.In addition,the situation is also an important factor in the decision-making process,people may judge the intention of the other party based on environmental information,and then influence the decision-making.Therefore,this study uses the inter-group parochial and universal cooperation(IPUC)game paradigm to explore the influence of social identity complexity on universal and narrow cooperation under different income structures and different frameworks.This study included a correlation study and two experiments,one to explore the relationship between social identity complexity and inter-group cooperation among Chinese college students,and the other to explore the relationship between social identity complexity and inter-group cooperation among Chinese college students,research 3 explores the impact of social identity complexity on universal and narrow cooperation under different frameworks.The results show that:(1)there is a positive correlation between social identity complexity and universal cooperation,and a negative correlation between social identity complexity and narrow cooperation.(2)the main effect of social identity complexity is significant.Compared with individuals with low social identity complexity,subjects with high social identity complexity have higher general level of cooperation,and the interaction between social identity complexity and income structure was significant.(3)the main effect of social identity complexity is significant.Compared with individuals with low social identity complexity,subjects with high social identity complexity have higher general level of cooperation.the main effect of different frame situations is significant,the subjects in the individual frame are more likely to choose general cooperation than those in the group frame,and the interaction between social identity complexity and different frame situations was significant. |
