The present study investigated the electrophysiological correlates of the psychological processing of the collective self-relevant stimulus using a three-stimulus oddball paradigm. The results showed that P300 amplitude elicited by the collective self-relevant stimulus was larger than those elicited by familiar and unfamiliar stimuli. In addition, N250 and P300 amplitudes elicited by subjects' own names were larger than those elicited by other name stimuli. In terms of lateralization of P300, the collective self-relevant effect was largest in the left region sites and the individual self-relevant effect was largest in the right region sites. Therefore, the present study extended previous findings by showing that the collective self, similar to the famous individual self, was psychologically important to humans.

    • "Therefore a conclusion could not be drawn here. Previous ERP studies focusing on self-relevant effect have revealed that the P200 (Hu et al., 2011; Mu & Han, 2010; Tacikowski, Cygan, & Nowicka, 2014), N250 (Tacikowski et al., 2014; Zhao et al., 2009), and P300 (Berlad & Pratt, 1995; Fan et al., 2011; Gray, Ambady, Lowenthal, & Deldin, 2004; Ninomiya et al., 1998; Tacikowski & Nowicka, 2010; Zhu et al., 2007), but not early components during the visual perception stage, are sensitive to self-related processing.

    ABSTRACT: Attachment is critical to each individual. It affects the cognitive-affective processing of social information. The present study examines how attachment affects the processing of social information, specifically maternal information. We assessed the behavioral and electrophysiological responses to maternal information (compared to non-specific others) in a Go/No-go Association Task with twenty-two participants. The results illustrated that attachment affected maternal information processing during three sequential stages of information processing. First, attachment affected visual perception, reflected by enhanced P100 and N170 elicited by maternal information as compared to others information. Second, compared to others, mother obtained more attentional resources, reflected by faster behavioral response to maternal information and larger P200 and P300. Finally, mother was evaluated positively, reflected by shorter P300 latency in a mother + good condition as compared to a mother + bad condition. These findings indicated that the processing of attachment-relevant information is neurologically differentiated from other types of social information from an early stage of perceptual processing to late high-level processing.

    • "Thus, the own hands' internal representation would sustain a higher perceptual enrichment than others hands, which would allow participants to prepare efficiently in advance for its presentation (see Tong and Nakayama 1999). Extensive evidence has highlighted the fact that selfreferential information is processed differently than nonself-related information (Craik et al. 1999; Fischler et al. 1987; Gilboa 2004; Graham et al. 2003; Kelley et al. 2002; Miyakoshi et al. 2007; Zhao et al. 2009). These findings have led to the idea that the representation of the self might be special, that is, that " it emerges from systems that are physically and functionally distinct from those used for more general purpose cognitive processing " (in Gillihan and Farah 2005).

    ABSTRACT: High-density electroencephalographic recordings were used to investigate the level of analysis at which attentional expectations modulate the processing of specific stimuli from the same perceptual category but differentiated in terms of a particular non-perceptual feature: body ownership. We used a task in which colour cues predicted whether a picture of a hand stimulus belonged to the participant or to somebody else. Participants were instructed to respond whether the target was a left or a right hand. Results revealed that the ERP pattern depended on stimulus ownership and attention orienting, which influenced the visual processing of own and someone else's hands differentially. Larger amplitude for others' than for own hands was shown at the N1 deflection (at the right hemisphere). Attentional effects were found at the P2 and P3 potentials. The P2 reflected an interaction between stimulus ownership and attentional orienting, due to a larger validity effect for others' hands. At the P3 level, the data showed a significant validity effect only for self-hand stimuli. In sum, our results suggest that (1) differences as a function of stimulus ownership can be detected at early levels of stimulus processing; (2) endogenous attention can be directed to exemplars within the same category, hand stimuli in this case; (3) the effects of attention are modulated by ownership.

    • "The number of epochs used to compute ERPs did not differ significantly between name categories. We analyzed ERP components that are commonly observed in person-recognition studies, i.e., P100, N170, N250 and P300 (Berlad and Pratt, 1995; Müller and Kutas, 1996; Folmer and Yingling, 1997; Schweinberger et al., 2002b, 2006; Gray et al., 2004; Perrin et al., 2005; Herzmann and Sommer, 2007; Zhao et al., 2009; Tacikowski and Nowicka, 2010; Tacikowski et al., 2011a; Cygan et al., 2014). Our analysis also included the P200 as some previous studies showed a selfpreference for this component (Mu and Han, 2010; Hu et al., 2011; Fan et al., 2013). "

    ABSTRACT: One's own name seems to have a special status in the processing of incoming information. In event-related potential (ERP) studies this preferential status has mainly been associated with higher P300 to one's own name than to other names. Some studies showed preferential responses to own name even for earlier ERP components. However, instead of just being self-specific, these effects could be related to the processing of any highly relevant and/or frequently encountered stimuli. If this is the case: (1) processing of other highly relevant and highly familiar names (e.g., names of friends, partners, siblings, etc.) should be associated with similar ERP responses as processing of one's own name and (2) processing of own and close others' names should result in larger amplitudes of early and late ERP components than processing of less relevant and less familiar names (e.g., names of famous people, names of strangers, etc.). To test this hypothesis we measured and analyzed ERPs from 62 scalp electrodes in 22 subjects. Subjects performed a speeded two-choice recognition task-familiar vs. unfamiliar-with one's own name being treated as one of the familiar names. All stimuli were presented visually. We found that amplitudes of P200, N250 and P300 did not differ between one's own and close-other's names. Crucially, they were significantly larger to own and close-other's names than to other names (unknown and famous for P300 and unknown for P200 and N250). Our findings suggest that preferential processing of one's own name is due to its personal-relevance and/or familiarity factors. This pattern of results speaks for a common preference in processing of different kinds of socially relevant stimuli.
