不同决策任务对后续的爱荷华博弈成绩的影响

Effect of Different Decision-making Tasks on Subsequent Performance of the Iowa Gambling Task

该文考察了难度不同的决策任务对其后的风险决策成绩的影响。实验中被试随机分为两组,分别完成充满个人情感的道德(Moral-personal)决策情境任务和与道德无关的(Non-moral)选择决策情境任务。接下来被试完成了相同的考察风险决策能力的爱荷华博弈任务。研究结果显示,相比Non-moral选择决策组,Moral-personal选择决策组的被试在后续的爱荷华博弈任务中成绩表现更差,做出了更多的不利选择。实验结果支持资源损耗的假说,越困难的决策任务调用和消耗了更多的资源,导致后续发生的任务资源不足而引起越差的成绩表现。

The experiment tried to investigate the influence of initial efforts at decision -making on a subsequent risk decision -making task, and revealed that the degree of difficulty in the prior decision - making task would have some effects on subsequent performance of decision - making task. Participants were randomly divided into two groups, some made moral - personal judgments, whereas the others faced to non -moral ones, and then they all finished the Iowa Gambling Task （IGT）. Behavioral results showed a worse performance in the subsequent IGT for people making moral - personal judgments than those making non - moral ones. Relative to non - moral group, moral - personal group tended to lose more money and was more likely to prefer the disadvantageous decks. These results support the theoretical hypothesis that decision - making process may deplete the resource and affect subsequent performance of risk decision - making. And moral - personal judgments often involving serious bodily harm or death to another person or people could be more exhaus- ted than non -moral ones, which suggest that more difficult decisions may lead to worse performance in a subsequent task.
