Recording event-related potentials in the meanwhile of processing the subjects' body pictures,the paper discusses the difference of early processing between the self-body and others' body.The result presents that there are three early components(N60,P100 and N170) evoked by self-body and others;body.The analysis on N60 presents nothing;P100 has the interactive effects on body picture genre and cognitive task genre,in the condition of the initiative body direction cognitive task,the P100 wave resulted from self body is higher that resulted from others' body;the analysis on N170 presents body style main effect,and N170 evoked by self body is higher than by others'.This result shows us: 170ms shall be the break point of processing of self body and others'.
