Theory of mind refers to the ability to attribute mental states to self and others, and predict actions in terms of mental states. It is still unclear how certain kinds of processing occur in theory of mind operation. The present study compared neural activities elicited by desire reasoning for self and for others under consistent or inconsistent conditions using the event-related potential method. The results showed that the late positive component (LPC) associated with desire reasoning was larger during the 450-550 ms time period in the condition of reasoning for self than that for others when desires were inconsistent. A left hemisphere effect on the scalp distribution was observed for the LPC component. The present study showed that a left frontal LPC component might reflect the subjective categorization process in desire reasoning.
心理理论是指将心理状态归因于自我和他人，并根据心理状态预测行为的能力。目前尚不清楚在心理理论操作中某些类型的加工是如何发生的。本研究采用事件相关电位方法，比较了在一致或不一致条件下，自我和他人欲望推理所引发的神经活动。结果表明，在欲望不一致时，自我推理条件下450-550毫秒时间段内与欲望推理相关的晚期正成分（LPC）大于他人推理条件下的。在头皮分布上观察到LPC成分存在左半球效应。本研究表明，左侧前额叶LPC成分可能反映了欲望推理中的主观分类过程。
