情绪在复杂决策中的作用可以通过爱荷华州赌博任务(IGT)来评估，IGT是一种广泛使用的神经心理测量工具，可能会从不同于传统测量方法评估的执行功能方面进行评估。最值得注意的是，关于牌面好坏的“感觉”，通常与IGT的表现有关，这似乎让人想起基于直觉的决策--这与长期以来对问题解决的“直觉”和“推理”风格进行对比的决策研究有关。为了验证IGT的表现更多地依赖于基于情绪的学习而不是传统的执行资源来实现正常表现的说法，一组参与者同时完成了IGT，并完成了两个次要任务中的一个，其中一个(随机数生成)已知会加载执行资源。第三组在没有次级任务的情况下进行IGT。如果IGT上的表现需要与直觉操作相关的特性，那么参与者在完成次要任务时不应该表现出干扰，或者至少在加载执行功能的次要任务上不应该表现出选择性中断。三组的学习速度没有显著差异。这表明，在认知架构中，随机数生成等传统执行任务所承载的认知资源种类与爱荷华州赌博任务绩效所需的基于情绪的学习技能并不重叠。目前的研究结果也与爱荷华州研究小组之前的说法一致，即基于情绪的学习和工作记忆资源是双重分离的。(C)2004 Elsevier Inc.保留所有权利。
The role of emotion in complex decision-making can be assessed on the Iowa Gambling Task (IGT), a widely used neuropsychological measure that may tap a different aspect of executive function than that assessed by conventional measures. Most notably, the 'feeling' about which decks are good or bad, often described in relation to IGT performance, seems reminiscent of decision-making based on intuition-linked to a long history of research in decision-making contrasting the 'intuition' versus 'reasoning' styles of problem solving. To test the claim that the performance on the IGT relies more on emotion-based learning than conventional executive resources for normal performance, a group of participants completed the IGT simultaneously with one of two secondary-tasks, one of which (random number generation) is known to load executive resources. A third group performed the IGT with no secondary-task. If performance on the IGT requires the properties associated with intuitive operations, then participants should either show no disruption when completing a secondary-task, or at least show no selective disruption on a secondary-task that loads for executive function. The rate of learning in the three groups was not significantly different. This suggests that the sorts of cognitive resources loaded by traditional executive tasks such as random number generation do not overlap, in the cognitive architecture, with the emotion-based learning skills that are required for Iowa Gambling Task performance. The findings of the present study are also consistent with a previous claim of the Iowa group that emotion-based learning and working memory resources are doubly dissociable. (C) 2004 Elsevier Inc.
