目前的研究检查了心率和皮肤电导变化的模式之前的风险选择和以下的结果为坏，中等，和良好的表现在爱荷华州赌博任务的模拟（Bechara，Damasio，Damasio，&安德森，1994）。该任务需要在四个选项中进行选择，其中两个选项后面是高奖励，并且不可预测地，损失更高（不利选项），另外两个选项后面是小奖励，但不可预测的损失也很小（有利选项）。预期心率减慢和皮肤电导水平较高，相对于有利的选择，但只有良好的表演者。相比之下，心率减慢和皮肤电导水平增加损失相对于奖励的结果，这些变化是相似的所有性能组。这些发现被解释为表明，表现不佳者的决策障碍是由次级诱导物（即，躯体标记），而不是由奖励和惩罚的主要诱导物产生的弱躯体反应。
The current study examined the pattern of heart rate and skin conductance changes preceding risky choices and following outcome for bad, moderate, and good performers on an analogue of the Iowa gambling task (Bechara, Damasio, Damasio, & Anderson, 1994). The task required a choice between four options, two options were followed by a high reward and, unpredictably, an even higher loss (disadvantageous options) and two other options were followed by a small reward but the unpredictable loss was also small (advantageous options). Anticipatory heart rate slowing and skin conductance level were higher preceding disadvantageous relative to advantageous options, but only for good performers. In contrast, heart rate slowed and skin conductance level increased following loss relative to reward outcomes, and these changes were similar for all performance groups. These findings were interpreted to suggest that decision-making impairments in bad performers arise from a weak somatic response generated by secondary inducers (i.e., somatic markers), rather than a weak somatic response generated by primary inducers of reward and punishment.
