Behavioral and neuroimaging studies have demonstrated that people process preferentially self-related information such as an image of their own face.Furthermore, people rapidly incorporate stimuli into their self-representation even if these stimuli do not have an intrinsic relation to self.In the present study, we investigated the time course of the processes involved in preferential processing of self-related information.In two EEG experiments three Buffered C unfamiliar faces were identified with verbal labels as either the participant, a friend, or a stranger.

Afterwards, participants judged whether two stimuli presented in succession (ISI = 1500ms) matched.In experiment 1, faces were followed by verbal labels and in experiment 2, labels were followed by faces.Both experiments showed the same pattern of behavioral and electrophysiological results.If the 6 Piece Outdoor Sectional first stimulus (face or label) was associated with self, reaction times were faster and the late frontal positivity following the first stimulus was more pronounced.

The self-association of the second stimulus (label or face) did not affect response times.However, the central-parietal P3 following presentation of the second stimulus was more pronounced when the second stimulus was preceded by self-related first stimulus.These results indicate that even unfamiliar faces that are associated to self can activate a self-representation.Once the self-representation has been activated the processing of ensuing stimuli is facilitated, irrespective of whether they are associated with the self.
