Exposure to monetary cues might affect charitable donations, but little is known about how monetary cues affect charitable donations from the neural perspective. The present study examined the effect of monetary cues on charitable donations by means of event-related potentials (ERPs). Participants primed with monetary or neutral images decided whether to accept donation offers with the high, moderate, and low costs. The behavioural results showed that in the money-primed condition, participants took more time to decide for the high-cost than for the moderate and low-cost donation offers. The ERP results showed that the P2 and P3 were larger in the money-primed condition relative to the neutral images condition. Notably, participants primed with money demonstrated larger P3 for the high-cost donation offers than for the moderate and low-cost offers, but this difference was not observed in the control condition. These findings indicate that people primed with money may pay more attention to the cost-relevant information related to their self-interests when conducting prosocial behaviours.
金钱线索的暴露可能会影响慈善捐赠，但从神经科学的角度来看，人们对金钱线索如何影响慈善捐赠知之甚少。本研究通过事件相关电位（ERP）技术考察了金钱线索对慈善捐赠的影响。参与者被呈现金钱或中性图片，然后决定是否接受高、中、低三种成本的捐赠。行为结果表明，在金钱启动条件下，参与者需要更多的时间来决定高成本的捐赠，而不是中、低成本的捐赠。ERP 结果显示，与中性图片条件相比，金钱启动条件下的 P2 和 P3 更大。值得注意的是，与中、低成本的捐赠相比，被金钱启动的参与者对高成本的捐赠表现出更大的 P3，但在控制条件下没有观察到这种差异。这些发现表明，当人们进行亲社会行为时，被金钱启动的人可能会更加关注与自身利益相关的成本相关信息。
