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 de-ceptive 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.

In order to detect cross-sectional age characteristics of cognitive neural mechanisms in audio-visual modal interference inhibition,event-related potentials(ERP) of 14 10-year-old children were recorded while performing the words interference task.In incongruent conditions,the participants were required to inhibit the audio interference words of the same category.The present findings provided the preliminary evidence of brain mechanism for the children's inhibition development in the specific childhood stage.
