• 摘要： 心理账户是个体在心理上对经济行为的编码、分类及评估的过程。心理账户的运算机制有其特定的区别于经济学的运算规则。本研究在现有的心理账户理论基础上，在对心理账户的运算机制充分验证后，运用事件相关电位(ERP)的方法对心理账户运算机制的神经机制进行了实验研究并得出了相关结论，为心理账户运算机制的相关理论提供了认知神经科学证据。结果显示：在反应时水平上，主效应不显著，商品种类×商品差额的交互作用显著[F(1,12)=7.042，p=0.021<0.05]；在正确率水平上，主效应不显著，商品种类×商品差额的交互作用显著[F(1,12)=14.897，p=0.002<0.05]。个体在进行心理账户运算时激活了前额叶脑区，对小商品出现差额时投入更多的认知加工资源。无论是商品差额的不同还是商品种类的不同均会对个体心理账户的认知加工产生影响。
• The psychological account is the process of the individual's psychological coding, classification and evaluation of economic behavior. The mechanism of calculating the mental account has its specific rules of economics. On the basis of the existing psychological account theory, this paper uses the event-related potential (ERP) method to study the neural mechanism of the mental account calculation mechanism after the full verification of the mental account mechanism, and draws the conclusion for the theory of computing mechanism in the mental account provides cognitive neurological evidence. The results show that at the level of response, the main effect is not significant, but the commodity category × commodity balance interaction significantly[F(1,12)=7.042，p=0.021<0.05]; at the correct rate level, the main effect is not significant, but the commodity category × commodity balance interaction significantly[F(1,12)=14.897，p=0.002<0.05]. Individuals in the psychological account operation to activate the refrontal brain area, the difference is more sensitive to small commodities. Whether it is the difference between the different goods or the different types of goods will have an impact on the individual mental accounts of cognitive processing.
