Exploring the valence-framing effect: Gain frame enhances behavioral and brain sensitivity to the failure of decision-making under uncertainty

摘要

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.
