最后通牒博弈中提议者情绪预测偏差对公平决策的影响:公平感知的作用

The Influence of Proposers’Affective Forecasting Bias on Fairness Decision in Ultimatum Game:The Mediating Effect of Fairness Perception

为探讨提议者情绪预测偏差对公平决策的影响以及其中介机制,采用了两轮最后通牒博弈提议者实验任务,第一轮测量分配方案被接受和拒绝的情绪预测偏差,第二轮测量提议者的分配方案。研究结果表明:(1)提议者情绪预测偏差影响公平决策;(2)公平感知在提议者情绪预测偏差与公平决策间起部分中介作用。研究认为,提议者对积极结果的情绪预测偏差,会降低其公平感知,进而降低其分配方案公平性;提议者对消极结果的情绪预测偏差,会提高其公平感知,进而增加其分配方案公平性。

To examine the influence of proposers’affective forecasting bias on fairness decision and its mediating mechanism,a two-round ultimatum game proposer experiment task was used.The first round measured the affective forecasting bias both in the forecasting of positive and negative outcome,and the second round measured the allocation offers.The results showed that:(1)Proposers’affective forecasting bias influenced fairness decision directly;(2)Fairness perception has a partial mediating effect between proposers’affective forecasting bias and fairness decision.Conclusion:Proposers’affective forecasting bias about positive outcome decreased the fairness perception,which in turn decreased the fairness of allocation decision;Proposers’affective forecasting bias about negative outcome increased the fairness perception,which in turn increased the fairness of allocation decision.
