The framing effect, which is one of the cognitive biases, can play a major role in changing preferences and the decision-making process. However, whether the gain and loss frames modulate the evaluation of feedback during decision-making is still unclear. In this study, we used event-related potentials (ERPs) with a Balloon Analogue Risk Task (BART) paradigm to examine the effects of a gain and loss frame on the evaluation of feedback during the decision-making process of the brain. Behavioral data showed an increased uncertainty-aversion, especially after receiving negative feedback (balloon explosion) during the completion of the BART in the gain frame relative to the loss frame. The ERP data demonstrated a more negative feedback-related negativity (FRN) after receiving negative feedback in the gain frame relative to the loss frame. Additionally, the FRN amplitude elicited by the negative feedback correlated with the future decision-making behavior in both the gain and loss frames. These findings demonstrated that, in comparison to the loss frame, the gain frame increased behavior and brain sensitivity to the failure of decision-making under uncertainty.
框架效应是认知偏差之一，它在改变偏好和决策过程中起着重要作用。然而，收益和损失框架是否调节决策过程中反馈的评估尚不清楚。在这项研究中，我们使用与气球模拟风险任务（BART）范式相关的事件相关电位（ERP）来检查收益和损失框架对大脑在 BART 完成过程中反馈评估的影响。行为数据显示，在收益框架下，特别是在完成 BART 时收到负面反馈（气球爆炸）后，不确定性规避增加。ERP 数据表明，在收益框架下收到负面反馈时，反馈相关负性波（FRN）更负。此外，收益和损失框架中负面反馈引起的 FRN 幅度与未来的决策行为相关。这些发现表明，与损失框架相比，收益框架增加了对不确定性下决策失败的行为和大脑敏感性。
