最近的决策双过程模型表明，情绪在决策中起着重要作用；然而，偶然情绪（即与当前情况无关的情绪）对决策的影响仍未得到充分探讨。这个问题是通过诱导两种基本情绪状态（娱乐或悲伤）来调查的，并与中性情绪控制组进行比较。决策是通过一个经过充分研究的社会任务——最后通牒游戏来评估的。在这项任务中，参与者必须决定接受或拒绝来自其他参与者的金钱提议，这些提议的不公平程度各不相同。情感是由电影短片引起的。诱导的悲伤与公平相互作用，悲伤程度越高，接受不公平待遇的几率越低。诱导的娱乐与决策中的任何显著偏见无关。这些结果表明，即使是微妙的偶然情绪也会在偏见决策中发挥重要作用。这些结果在情感、认知神经科学和临床文献方面的意义进行了讨论。
Recent dual-process models of decision making have suggested that emotion plays an important role in decision making: however, the impact of incidental moods (i.e., emotions unrelated to the immediate situation) on decisions remains poorly explored. This question was investigated by inducing 2 basic emotional states (amusement or sadness) that were compared with a neutral-emotion control group. Decision making was assessed with a well-studied social task, the Ultimatum Game. In this task, participants had to make decisions to either accept or reject monetary offers from other players, offers that varied in their degree of unfairness. Emotion was induced with short movie clips. Induced sadness interacted with otter fairness, with higher sadness resulting in lower acceptance rates of unfair offers. Induced amusement was not associated with any significant biases in decision making. These results demonstrate that even subtle incidental moods can play an important role in biasing decision making. Implications of these results in regards to the emotion, cognitive neuroscience, and clinical literatures are discussed.
