Recent research suggests that exposure to monetary cues strengthens an individual's motivation to pursue monetary rewards by inducing the 'market mode' (i.e. thinking and behaving in accordance with market principles). Here, we examined the effect of market mode on social reward processes by means of event-related potentials (ERPs). Participants primed with monetary images or neutral images acted as advisors who selected one of two options for a putative advisee. Subsequently, all participants passively observed the advisee accepting or rejecting their advice and receiving a gain or loss outcome. After money priming, the feedback-related negativity (FRN) to the advisee's gain/loss outcome was larger following incorrect as compared to correct advice irrespective of whether the advice had been accepted or rejected. A smaller P3 following incorrect advice showed only when the advice was rejected. After neutral priming, the FRN was larger for incorrect relative to correct advice only when the advice had been rejected. However, the P3 was larger for correct relative to incorrect advice irrespective of the advisee's final choice. These findings suggest that the market mode facilitates early and automatic feedback processing but reduces later and controlled responding to outcomes that had been accepted.
最近的研究表明，金钱线索的暴露通过诱导“市场模式”（即根据市场原则进行思考和行为），增强了个体追求金钱奖励的动机。在这里，我们通过事件相关电位（ERP）来研究市场模式对社会奖励过程的影响。参与者被启动金钱图片或中性图片，作为顾问为假定的被顾问者选择两个选项之一。随后，所有参与者被动观察被顾问者接受或拒绝他们的建议以及获得收益或损失的结果。在金钱启动后，无论建议是否被接受，与正确建议相比，被顾问者的收益/损失结果的反馈相关负波（FRN）在错误建议后更大。只有当建议被拒绝时，较小的 P3 才会显示。在中性启动后，只有当建议被拒绝时，错误建议相对于正确建议的 FRN 更大。然而，无论被顾问者的最终选择如何，正确建议相对于错误建议的 P3 更大。这些发现表明，市场模式促进了早期和自动的反馈处理，但减少了对已被接受的结果的后期和控制反应。
