We investigated whether experienced regret influences risky decision making in future dissimilar situations and whether this effect is affected by risky degree. Therefore, participants (N = 39 and 54 in Experiment 1 and 2, respectively) were asked to select one of the two options. In the experienced regret condition, the selected option was worse than the unselected option; in the control condition, the information about the unselected option was unknown to the participants. Subsequently, participants were required to either keep the selected option or to gamble. Additionally, Experiment 2 varied in risky degree of the gamble from low to high. Results showed that experienced regret enhanced possibilities of gamble under low risk (Experiment 1 and 2). Under high risk, however, the effect of experienced regret was reversed (Experiment 2). The findings might suggest that experienced regret affects risky decision making in future dissimilar situations dependently on risky degree.

经历后悔对风险决策的影响取决于风险程度

我们调查了经历的后悔是否会影响未来不同情况下的风险决策，以及这种影响是否受风险程度的影响。因此，参与者（N = 39 和 54 在实验 1 和 2，分别）被要求选择两个选项之一。在经历后悔的情况下，选择的选项比未选择的选项差；在控制条件下，参与者不知道有关未选择选项的信息。随后，参与者被要求要么保留所选选项，要么进行赌博。此外，实验2的赌博风险程度从低到高不等。结果表明，经历过的后悔增加了在低风险下赌博的可能性（实验 1 和 2）。然而，在高风险下，经历后悔的影响被逆转（实验 2）。研究结果可能表明，经历的后悔会影响未来不同情况下的风险决策，这取决于风险程度。
