Understanding others mind and interpersonal interaction are the cognitive basis of successful social interactions. People's mental states and behaviors rely on their holding beliefs for self and others. To investigate the neural substrates of false belief reasoning, the 32 channels event-related potentials (ERP) of 14 normal adults were measured while they understood false-belief and true belief used deceptive appearance task. After onset of the false-belief or true-belief questions, N100, P200 and late negative component (LNC) were elicited at centro-frontal sites. Compared with true belief, false belief reasoning elicited significant declined LNC in the time window from 400 to 800 ms. The source analysis of difference wave (False minus True) showed a dipole located in the middle cingulated cortex. These findings show that false belief reasoning probably included inhibitive process.
理解他人的心智和人际互动是成功社交互动的认知基础。人们的心理状态和行为依赖于他们对自己和他人所持有的信念。为了研究错误信念推理的神经基础，在14名正常成年人通过欺骗性外表任务理解错误信念和真实信念时，测量了他们32通道的事件相关电位（ERP）。在错误信念或真实信念问题出现后，在额中央部位引出了N100、P200和晚期负成分（LNC）。与真实信念相比，错误信念推理在400至800毫秒的时间窗口内引发了显著下降的LNC。差异波（错误减去真实）的源分析显示一个偶极子位于扣带中部皮质。这些发现表明，错误信念推理可能包括抑制过程。
