摘　　要：研究从金钱补偿的视角考察社会排斥对不确定性决策的影响以及金钱激励的调节作用。实验发现,有金钱激励时,被排斥者在爱荷华赌博任务(Iowa gambling task,IGT)中的行为分数(组块2和3的选牌净分数和总的盈利分数)显著高于社会接纳者,表现为风险规避;在无金钱激励时,被排斥者在IGT任务中的行为分数(组块4和5的选牌净分数和总的盈利分数)显著低于被接纳者,表现为风险寻求。实验结果表明社会排斥对不确定性决策的影响受到金钱激励的调制。Inthe current study,we conducted a behavioral experiment with an Iowa gambling task to test the effects of social exclusion ondecision-making under uncertainty,as well as how money regulated the relationship between them.The results revealed that the excluded participants preferred the safety choice(blocks 2 and 3)compared tothe included and got higher net scores and total earnings when they were motivated by monetary reward.However,when there was no financial incentive,the excluded participants obtained significantly lower net scores(blocks 4 and 5)and total earnings relative to the included participants.In conclusion,this study demonstrated that the monetary rewards regulated the effects of social exclusion on decision-making under uncertainty in the Iowa gambling task.
