A growing body of research has largely confirmed and supported the idea that experimental sleep loss, such as sleep deprivation or sleep restriction, could affect individuals' risk-taking behavior and brain activity. However, whether self-reported sleep quality resulting from daily life modulates how feedback is evaluated during decision-making is still unclear. In this study, we used event-related potentials (ERPs) with a Balloon Analogue Risk Task (BART) to investigate how self-reported daily sleep quality modulates the brain's response to feedback from decision-making in the gain and loss frames. Behavioral data showed an increased aversion to uncertainty in the gain frame relative to the loss frame for individuals with higher sleep quality. However, this was not true for individuals with lower voluntary sleep quality. Similarly, the ERP data demonstrated that individuals with lower self-reported daily sleep quality displayed no changes in feedback-related negativity (FRN) in response to outcomes from decision-making in the gain and loss frames; however, individuals with higher self-reported daily sleep quality showed a greater FRN in response to decision-making in the gain frame than that in the loss frame. A Pearson correlation analysis showed that self-reported daily sleep quality was positively related to the variance of the FRN amplitude in response to the gain and loss frames. These findings suggest that framing effects on decision-making under uncertainty may depend on self-reported daily sleep quality and that the effects disappear when the sleep quality declines.
越来越多的研究在很大程度上证实并支持了这样一种观点，即实验性睡眠缺失，如睡眠剥夺或睡眠限制，可能会影响个体的冒险行为和大脑活动。然而，日常生活中自我报告的睡眠质量是否会调节决策过程中对反馈的评估仍不清楚。在本研究中，我们使用事件相关电位（ERP）结合气球模拟风险任务（BART）来探究自我报告的日常睡眠质量如何调节大脑在收益和损失框架下对决策反馈的反应。行为数据显示，睡眠质量较高的个体在收益框架下相对于损失框架对不确定性的厌恶增加。然而，对于自愿睡眠质量较低的个体来说并非如此。同样，ERP数据表明，自我报告的日常睡眠质量较低的个体在收益和损失框架下对决策结果的反馈相关负波（FRN）没有变化；然而，自我报告的日常睡眠质量较高的个体在收益框架下对决策的FRN大于损失框架下的FRN。Pearson相关分析表明，自我报告的日常睡眠质量与收益和损失框架下FRN振幅的方差呈正相关。这些发现表明，不确定性下决策的框架效应可能取决于自我报告的日常睡眠质量，并且当睡眠质量下降时这些效应会消失。
