Although the influence of endogenous emotion on decision-making has been widely studied, the effect of interpersonal emotions on risk decision-making is less understood. To address this issue, participants were asked to perform an interpersonal gambling game after perceiving their cooperator's facial emotions. The results found that the cooperator's happy expressions increased individuals' risk-approaching choice compared with angry expressions. Moreover, happy expressions induced larger P300 potentials in the option assessment stage, and diminished the differences between losses and wins in feedback-related FRN/RewP in the outcome valuation stage. Additionally, single-trial analysis found that the neural response induced by interpersonal expressions and feedback could predict participants' subsequent decision-making. These findings suggest that interpersonal emotions shape individuals' risk preference through enhancing in-depth valuation in the option assessment stage and early motivational salience valuation in the outcome valuation stage.
尽管内源性情绪对决策的影响已得到广泛研究,但人际情绪对风险决策的影响却鲜为人知。为解决这一问题,研究人员要求参与者在感知到合作对象的面部情绪后进行一场人际赌博游戏。结果发现,与愤怒表情相比,合作对象的快乐表情会增加个体的风险趋近选择。此外,快乐表情在选项评估阶段诱发了更大的P300电位,并在结果评估阶段缩小了损失与收益在反馈相关FRN/RewP上的差异。此外,单次试验分析发现,人际表情和反馈诱发的神经反应可以预测参与者随后的决策。这些发现表明,人际情绪通过在选项评估阶段增强深度评估以及在结果评估阶段增强早期动机显著性评估来塑造个体的风险偏好。
