Although the role of emotional processing is central to contemporary models of risky decision making, to date the role of trait emotional understanding has not been explored experimentally in this context. The current experiment (N=326) explores the role of alexithymia with respect to performance on the standard Iowa Gambling Task (IGT) and a version where cumulative financial feedback is obscured. Standard learning on the IGT was observed for those low in alexithymia. Those high in alexithymia learned to avoid disadvantageous decks over the first half of the task. However, over the later trials they showed a change in performance, shifting from advantageous to disadvantageous and back to advantageous decks again (termed an "explore-learn-change-return" strategy). It is argued that this is due to an inability to fully consolidate earlier learning and reduced sensitivity to losses. The absence of cumulative feedback independently resulted in reduced performance.
尽管情绪处理在当代风险决策模型中起着核心作用，但迄今为止，特质情绪理解在这方面的作用尚未在实验中得到探索。本实验（N=326）探讨了述情障碍在标准爱荷华赌博任务（IGT）和一个累积财务反馈被隐藏的版本上的表现中的作用。对于那些述情障碍程度较低的人来说，他们在 IGT 上的标准学习表现是可以观察到的。那些述情障碍程度较高的人在任务的前半段学会了避免不利的牌组。然而，在后来的试验中，他们的表现发生了变化，从有利的牌组转向不利的牌组，然后又回到有利的牌组（称为“探索-学习-改变-返回”策略）。这是因为他们无法完全整合早期的学习，并且对损失的敏感性降低。而没有累积反馈则会导致表现下降。
