“…For example, Chen et al (2008) explored the temporal features of self-referential processing evoked by handwriting; significant ERP differences were found between own and other handwriting conditions in the time windows 200-500 ms (N2 and P3 components) and 1000-2000 ms (LPC). Similarly, Su et al (2010) observed that own hand elicited more positive components than did other hand in the time window 350-600 ms (P3 and LPC).…”

“…As a result, four components (P2, N2, P3 and the positive slow wave) showed different amplitudes across task conditions and/or groups. In this study we analyzed the four ERP components across different sets of electrodes according to both the ERP topographies and relevant literature (Chen et al 2008;Silva et al 2008;Su et al 2010). The peak amplitude and the peak latency of the P2 component were calculated at F5 and F6 electrode sites (peak detection window 160-260 ms).…”

“…Self-relevant effects indexed by enhanced P3 amplitudes also have been found in autobiographical self-relevant stimuli (e.g. the subject's phone number, the name of the subject's pet, and the name of the subject's hometown), pictures of the subject's hand, and images of the subject's handwriting [2], [7], [8].…”

The present study investigated neural correlations underlying the psychological processing of stimuli with various degrees of self-relevance. Event-related potentials were recorded for names that differ in their extent of relevance to the study participant. Participants performed a three-stimulus oddball task. ERP results showed larger P2 averaged amplitudes for highly self-relevant names than for moderately self-relevant, minimally self-relevant, and non-self-relevant names. N2 averaged amplitudes were larger for the highly self-relevant names than for the moderately self-relevant, minimally self-relevant, and non-self-relevant names. Highly self-relevant names elicited larger P3 averaged amplitudes than the moderately self-relevant names which, in turn, had larger P3 values than for minimally self-relevant names. Minimally self-relevant stimuli elicited larger P3 averaged amplitudes than non-self-relevant stimuli. These results demonstrate a degree effect of self-reference, which was indexed using electrophysiological activity.

“…However, Tacikowski et al (2014) found that no significant differences were present on P2 amplitudes between participants' own names and the names of their friends (Tacikowski et al, 2014). Su et al (2010) also found that the hand of the participant and the hand of a stranger elicited equivalent P2 amplitudes and latencies (Su et al, 2010). The inconsistent results observed in these studies may be attributed to the different experimental stimuli and paradigm used; the effects of stimulus familiarity and taskrelevance should be considered in future studies regarding selfprocessing (Su et al, 2010;Tacikowski et al, 2014).…”

Previous studies have widely shown that self-esteem modulates the attention bias towards social rejection or emotion-related information. However, little is known about the influences of self-esteem on attention bias towards self-relevant stimuli. We aimed to investigate neural correlates that underlie the modulation effect of self-esteem on self-relevant processing. Event-related potentials (ERP) were recorded for subjects' own names and close others' names (the names of their friends) while subjects performed a three-stimulus oddball task. The results showed larger P2 amplitudes for one's own name than for close-other's name in the low self-esteem group, whereas this P2 effect were not observed in the high self-esteem group. In addition, one's own name elicited equivalent N250 amplitudes and larger P3 amplitudes compared with close-other's name in both high and low self-esteem groups. However, no interaction effects were observed between self-esteem and self-relevant processing in the N250 and P3 components. Thus, we found that the modulation effects of self-esteem on self-relevant processing occurred at the early P2 stage, but not at the later N250 and P3 stages. These findings reflect that individuals with low self-esteem demonstrate automatic attention towards their own names.
