Abstract: | 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.
