The Influence Of Interpersonal Trust On Cooperative Behavior And Expectation During Economic Decision-making

The problem of interpersonal trust has been paid close attention to by sociology,economics,psychology and so on.Even though the research on the relationship between interpersonal trust and cooperation has been going on since 1750 s,it was still not unified and there were still some contradictory results.For example,some researchers believed that interpersonal trust can positively predict cooperation,and other believed that interpersonal trust and cooperation were not related.Some studies had pointed out that the reason for this phenomenon might be the inconsistency of interpersonal trust in definition and classification,and few studies had distinguished interpersonal trust into trait trust and state trust.According to the development theory of trust,there was state trust that can change dynamically.According to the mandatory norm theory,there was a stable trust characteristic that exceeded the probability level.In addition,for the cooperative interaction objects,the cooperation of the behavior sender and the cooperative expectation of the receiver were the important study contents of the cooperation.This paper explored the influence of trait trust and state trust on cooperative behavior and expectation under the economic decision-making task of trust game and ultimatum game,and attempted to establish a "environment-individual-behavior" ternary interaction system model of trait trust,state trust,cooperative behavior and expectation to refine the relationship between them.There were three studies in total.Study 1 explored the relationship between trait trust and cooperative behavior and expectation through experiments.Study 2 explored the relationship between state trust and cooperative behavior and expectation through experiments.Study 3 explored the real-time interaction between the trait trust,state trust,cooperative behavior and expectation of the two interacting parties in a simulated situation.Study 1 showed that trait trust predicted cooperative behavior and expectation positively.Study 2 showed that state trust predicted cooperative behavior and expectation positively.Study 3 showed that the main effect of state trust on cooperative behavior was significant,the main effect of trait trust and the interaction between them were not significant;the main effect of trait trust on cooperative expectation was significant,the main effect of state trust was not significant,and the interaction between them was marginal significant.The above results showed that the individual's trait trust in the first interaction was the premise of expecting others to cooperate and also the condition of producing cooperative behavior during the economic decision-making task.The state trust of experienced in others in the second interaction was an important influencing factor for the individual to make cooperative behavior decisions and expect others to cooperate.However,in the simulated situation,the individual's cooperative behavior is only affected by state trust,while the cooperative expectation is affected by both trait trust and state trust.
