In the present study we explored the cerebral mechanisms underlying self processing relative to one’s own name by recording event-related potentials (ERPS). In the experiment, pictures of big circles, small circles, and names were presented to subjects randomly, and subjects were asked to discriminate small and big circle, while names were task-irrelevant stimulus. The results showed that subject’s own name (SON) elicited larger P2 and P3 amplitudes than did famous name (FN) and unfamiliar name (UFN). While different from previous studies, present study discovered the “self name effect” on P2 amplitude, that is, self processing relative to one’s own name could occurred at not only later P3 stage but also earlier P2 stage. Therefore, self processing relative to one’s own name maybe involve early and late two different stages, and the early one maybe automatic process , while the late one maybe conscious process.
