Self-reported daily sleep quality modulates the impact of the framing effect on outcome evaluation in decision-making under uncertainty: An ERP study.

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.
