考虑到使用爱荷华赌博任务（IGT）的研究结果，对自己行为预期结果的基于情绪的敏感性已被认为是做出有利决策的重要因素。执行IGT的假设检验对于学习正确的规则和引发自主反应是必不可少的。在这项研究中，参与者被要求专注于假设检验，以学习任务中与IGT相似的未公开规则，而不是最大化金钱奖励。在卡片选择之前和反馈之后，皮肤电导反应（SCRs）的振幅随着参与者对任务规则的准确理解而减弱。scr的衰减是由于继续假设检验的动机降低。我们的发现提供了一些证据，表明观察到的自主神经反应部分反映了与假设检验相关的情绪反应。
Given the results of studies using the Iowa Gambling Task (IGT), emotion-based sensitivity to an anticipated outcome of one’s own behavior has been suggested to be a significant factor in making advantageous decisions. Hypotheses-testing in performing IGT is essential for learning correct rules and elicits autonomic reactivity. In this study, participants were asked to concentrate on hypothesis-testing to learn undisclosed rules in the task which framework was similar to the IGT, rather than maximizing monetary reward. The amplitudes of skin conductance responses (SCRs) prior to card selection and following feedback were attenuated as participants came to accurately comprehend the task rules. The attenuation of SCRs resulted from reduced motivation to continue the hypotheses-testing. Our findings provide some evidence that observed autonomic responses partially reflect emotional reactions associated with the hypothesis-testing.
