Previous studies have reported that when people self-reflect--they typically judge the self as more positive (or less negative) compared to others on a range of dimensions (such as health, social skills, or achievement). In the present study, we investigated whether viewing the self through the eyes of other people reduces this egocentric (self-centered) bias. Event-related brain potentials (ERPs) were examined in 17 subjects who performed judgments of adjectives in positive or negative valences from either self-perspective or other-perspective. Reaction times revealed an interaction between the factors perspective and emotional valence. Faster responses occurred after positive words in the self-perspective condition. A similar interaction was observed in the ERP waveforms in the time range of the N400 component: smaller N400 amplitudes were elicited by positive stimuli compared to negative stimuli in the self-perspective condition, but not in the other-perspective condition. Similarly, a reversed pattern was found in the late positive component (LPC) at 415-815 ms. The present study suggests that shifts in perspectives between self and others can change self-appraisal, which in turn reduces egocentric biases of the self. On a neural level, this modulation may be associated with an increase in self-monitoring processes.

A growing number of studies have demonstrated preferential processing of self-related information. However, previous research has been limited in examining the distinction between processes related to the self and those related to the non-self, it remains unclear how self-related information with differing levels of importance is processed within the self. The present study examined how the importance of self-related content affects the neural activity involved in self-referential processing. The behavioral results showed that the participants had faster responses to more important self-related content. The event-related potential (ERP) results showed that early attention resources were diverted to the identification of highly important self-related content compared with minimally important self-related content, as reflected by the enhanced P200. Furthermore, the N200 amplitude for highly important self-related content was smaller than for moderately important self-related content which, in turn, were smaller than minimally important self-related content. Moreover, the P300 amplitudes were modulated by the degree of importance of self-related content, whereby a higher importance of self-related content led to larger P300 amplitudes. Taken together, these findings demonstrate an effect of the degree of importance of the self-related content at both behavioral and neurophysiological levels.

Previous research about group perception in terms of warmth and competence focused on the effects of social structural factors but overlooked the role of the fundamental group characteristic (i.e., entitativity or groupiness). Three studies were conducted to examine people’s perception of high/low entitativity groups under various functional relations. In Study 1, we experimentally created the target group (i.e., Group X) and manipulated entitativity and functional relation. In Studies 2 and 3, we chose a real group (i.e., Uyghurs) as the target group and measured cues to entitativity (Study 2) or entitativity itself (Study 3) and interethnic relations. In all studies, participants rated the target group on warmth and competence dimensions. The results suggested that, under cooperative functional relation, the group with higher entitativity was perceived as more competent and warmer, thereby more beneficial. Conversely, when the functional relation was conflictive, the group with higher entitativity was perceived as more competent but colder, and thus more harmful.

Findings on the effect of power on corruption are mixed. To make sense of these mixed results, three studies were conducted to examine the moderating role of status on this effect. In Study 1, corrupt intent was measured using a corruption scenario that contained manipulations of power and status. In Study 2, corrupt behaviour was measured in a corruption game that contained manipulations of power and status. Study 3 was conducted in real organisational settings, and aimed to expand the external validity of Studies 1 and 2. The results of all three studies consistently indicated that the effect of power was moderated by status. Specifically, power increased corruption when status was low, whereas this effect disappeared when status was high. The implications of reducing the facilitating effect of power on corruption by considering status from the perspective of social hierarchy are discussed.
