Data for: Ego Depletion Decreases Risk-Taking on the Columbia Card Task: The Moderating Role of Task Features

Previous exertions of self-control can affect subsequent risk preferences usually resulting in risk-seeking tendencies. A few studies, however, have found that reductions in self-control resources (i.e., “ego depletion”) can decrease risk-taking resulting in relative risk-aversion compared to non-depleted controls. Using the Columbia Card Task (CCT), we found that the ego depleted risked less than their non-depleted counterparts when task features promoted feelings of perceived control. Manipulations aimed at reducing perceived control eliminated this depletion effect and descriptively reversed the trend so that the ego depleted were risking more than the controls. We replicated the observed decrease in risk-taking among depleted individuals and showed that the results were not due to depletion increasing passivity or task disengagement.

先前的自我控制投入会影响后续的风险偏好，通常会引发风险寻求倾向。不过已有少数研究发现，自我控制资源的损耗（即自我损耗（ego depletion））会降低风险行为，与未被损耗的对照组相比，表现出相对的风险规避倾向。本研究采用哥伦比亚卡片任务（Columbia Card Task, CCT），发现在任务特征能够提升个体感知控制感的情境下，经历自我损耗的被试比未被损耗的对照组被试的冒险意愿更低。而旨在降低感知控制感的实验操纵则消除了这一自我损耗效应，且在描述层面反转了该趋势：此时经历自我损耗的被试的冒险意愿高于对照组。本研究重复验证了损耗个体风险行为降低的观测结果，并证明该结果并非由自我损耗提升被动性或任务脱离所致。本研究附带了数据与语法脚本文件。若需了解更多关于本数据集的信息，请联系Ryan Corser，邮箱：[e-mail]
