Love of money (LOM) is concerned with the attitude toward money, which can be measured by the LOM scale through affective, behavioral, and cognitive dimensions. Research has observed that monetary attitude was tightly related to reward processing and could affect economic behavior. This study examined how monetary attitude modulated risky behavior and the underlying neural mechanisms of reward processing using event-related potential (ERP) technique. We compared both the risk level and brain responses of a high-level LOM (HLOM) group to a low-level LOM (LLOM) group using a simple gambling task. The behavioral results showed that the HLOM group was more risky than the LLOM group, particularly after loss. The feedback-related negativity (FRN) was measured as the difference wave (gain-related ERP was subtracted from loss-related ERP). The FRN difference wave was larger in the HLOM group than that in the LLOM group. The P3 in the HLOM group was more positive than that in the LLOM group. These results suggest that monetary attitude can modulate both the underlying neural mechanisms and behavioral performance in a reward-related task. The HLOM participants are more sensitive to gain/loss than the LLOM participants.
对金钱的热爱（LOM）涉及到对金钱的态度，可以通过 LOM 量表从情感、行为和认知维度来衡量。研究表明，金钱态度与奖励处理密切相关，并可能影响经济行为。本研究使用事件相关电位（ERP）技术考察了金钱态度如何调节风险行为和奖励处理的神经机制。我们使用简单的赌博任务比较了高水平 LOM（HLOM）组和低水平 LOM（LLOM）组的风险水平和大脑反应。行为结果表明，HLOM 组比 LLOM 组更具冒险性，尤其是在损失之后。反馈相关负波（FRN）被测量为差异波（增益相关 ERP 减去损失相关 ERP）。与 LLOM 组相比，HLOM 组的 FRN 差异波更大。HLOM 组的 P3 比 LLOM 组更积极。这些结果表明，金钱态度可以调节奖励相关任务中的神经机制和行为表现。与 LLOM 参与者相比，HLOM 参与者对收益/损失更为敏感。
