It has been suggested that affective states can guide higher level cognitive processes and that such affective guidance may be particularly important when real-life decisions are made under uncertainty. We ask whether affect guides decisions in a laboratory task that models real-life decisions under uncertainty. In the Iowa gambling task (IGT), participants search for monetary payoffs in an uncertain environment. Recent evidence against an affective guidance interpretation of the IGT indicates a need to set a standard for what counts as evidence of affective guidance. We present a novel analysis of IGT, and our results show that participants' galvanic skin response (GSR) reflects an affective process that precedes and guides cognition. Specifically, prior to participants' knowledge of the optimal strategy, their GSRs are significantly higher when they are about to select from a bad deck, relative to a good deck, and this difference in GSR is correlated with a behavioral preference for the good deck.
有人认为，情感状态可以引导更高层次的认知过程，并且当在不确定性条件下做出现实生活中的决策时，这种情感引导可能尤为重要。我们研究在一个模拟不确定性条件下现实生活决策的实验室任务中，情感是否会引导决策。在爱荷华赌博任务（IGT）中，参与者在不确定的环境中寻找金钱回报。最近反对对IGT进行情感引导解释的证据表明，需要为构成情感引导证据的标准设定一个标准。我们对IGT进行了一项新颖的分析，结果表明参与者的皮肤电反应（GSR）反映了一个先于并引导认知的情感过程。具体而言，在参与者了解最优策略之前，当他们即将从差牌组中选择时，相对于好牌组，他们的GSR显著更高，并且GSR的这种差异与对好牌组的行为偏好相关。
