The Impact Of Feedback And Psychological Distance On Self-Other Risk Decisions

Self-other risk decision making difference has been controversial,to examine and confirm the previous self-other differences in risk decision making,and to explore the impact of monetary feedback and social feedback on self-other risk decision making,help to promote people decision making level.Experiment 1 investigated the difference between self-other risk decision making when using the behavior experiment cups task,found that compared to decision for strangers,self decision and decision for friends are more conservative,but self decision making is more risk than for friend;compared with no feedback condition and error feedback condition,the individual is more adventurous in the correct feedback condition.it was more risky to make decisions for strangers than to make decisions for friends and self.In experiment 2,the study of the influence of monetary feedback on the self-others risk decision was investigated by using the EEG experiment of the cups task.The results were found that(1)compared with the money feedback of positive and zero feedback,individual under the condition of negative feedback decision is more risk;(2)decision making stage:the positive and negative feedback of money induced greater P2 and N2 amplitude.(3)the outcome evaluation stage:in the negative feedback of money,compared with the decision for the stranger,the self decision and decision for friends evoked the P300 amplitude were larger.Experiment 3 used EEG experiment of the cups task.The task investigates social feedback effects on self-other risk decision making,the results found(1)individual decision making for strangers was more risky than decision for friends;(2)decision making stage:Positive emotional feedback evoked a larger N1 amplitude,and negative emotional feedback evoked a larger amplitude of P2,N2,and P300.In the negative emotional feedback,compared with the decision for the stranger,self decision and decision for friends evoked greater P2 and P300 amplitude.(3)the outcome evaluation stage:The decision for strangers induces a greater N1 amplitude.Negative emotional feedback induces greater amplitudes of FRN and P300.Among them,in the negative emotion feedback,compared to the decision for stranger,self decision evoked the P300 amplitude were larger.These results show that the psychological distance and feedback are important factors affecting self-other risk decision making,the decision which to strangers more risky than self decision and decision for friends,and social feedback is more influence on individuals than money feedback.Therefore,this study can use its advantages and disadvantages to help individual decision making by understanding the role of feedback in decision making,and it can further investigate the role of feedback in different decision making areas to optimize decision-making.
