Abstract
The psychological mechanisms that high and low altruists exhibit in different contexts remain unknown. This study examined the underlying mechanisms of the effect of altruistic personality, social observation, and interpersonal distance on prosocial behavior using event-related potentials (ERPs). Participants with high and low altruism were asked to make prosocial or non-prosocial choices toward different interpersonal distances (friends, acquaintances, or strangers) under the (non)observer condition. The electrophysiological responses to the choice stimuli were simultaneously recorded. The behavioral results demonstrated that high altruists had more prosocial choices, and these choices were unaffected by interpersonal distance and social observation. However, low altruists made more prosocial choices toward friends and acquaintances under the observer than nonobserver conditions, whereas their prosocial choices toward strangers showed no difference. The ERP results demonstrated that low altruists showed more negative N2 when the choice stimuli were toward strangers and acquaintances or under the nonobserver condition. Furthermore, low altruists showed larger P3 under the observer than nonobserver conditions when the choice stimuli were toward friends and acquaintances, while this difference was absent when the choice stimuli were toward strangers. However, for high altruists, no effect of interpersonal distance and social observation was observed in N2 and P3. These results suggest that the prosocial behavior of low altruists is mainly driven by reputational incentives, whereas high altruists are primarily motivated by concern about the well-being of others. Our findings provide insights into the prosocial behavior of high and low altruists in different contexts and support the empathy-altruism hypothesis.

Biol Psychol 2023; 178:108519.

Abstract
Pro-environmental behavior benefits the environment but is individually costly. Therefore, understanding the neural processes of pro-environmental behavior can advance our knowledge of its implicit cost-benefit calculations and mechanisms. Previous studies have focused separately on the effects of social distance and social observation on explicit pro-environmental behavior responses, yet the underlying neurophysiological mechanism remains unknown. Using the event-related potentials (ERPs), we investigated the neural responses to the effects of social distance and social observation on pro-environmental behavior. Participants were instructed to decide between self-interest and pro-environmental choices towards different social distance targets (family members, acquaintances, or strangers) under observable and non-observable conditions. The behavioral results demonstrated that the rate of pro-environmental choices towards acquaintances and strangers was higher under the observable condition than under the non-observable condition. Nonetheless, the rate of pro-environmental choices was higher-unaffected by social observation-towards family members than towards acquaintances and strangers. The ERP results showed that the P2 and P3 amplitudes were smaller under the observable than under the non-observable condition when the potential bearers of environmental decisions were acquaintances and strangers. However, this difference did not emerge when the potential bearers of environmental decisions were family members. The ERP findings of smaller P2 and P3 amplitudes suggest that social observation may reduce the deliberate calculation of personal costs, thereby promoting individuals' pro-environmental behaviors towards acquaintances and strangers.

Biol Psychol 2023; 177:108506.

Abstract
Previous work has demonstrated the interpersonal implications of advisees' decisions (acceptance or rejection) on advisors' advice-giving behavior in subsequent exchanges. Here, using an ERP technique, we investigated how advisees' facial feedback (smiling, neutral, or frowning) accompanying their decisions (acceptance or rejection) influenced advisors' feedback evaluation from advisees and their advice-giving in subsequent exchanges. Behaviorally, regardless of whether the advice was accepted or rejected, advisors who received smiling-expression feedback would show higher willingness rates in subsequent advice-giving decisions, while advisors who received frowning-expression feedback would show lower willingness rates. On the neural level, in the feedback evaluation stage, the FRN and P3 responses were not sensitive to facial feedback. In contrast, frowning-expression feedback elicited a larger LPC amplitude than neutral- and smiling-expression feedback, regardless of whether the advice was accepted or rejected. In the advice decision stage, advisors who received neutral-expression feedback showed a larger N2 in making decisions than advisors who received frowning-expression feedback only after the advice was rejected. Additionally, Advisors who received smiling- and neutral-expression feedback showed a larger P3 in making decisions than advisors who received frowning-expression feedback only after the advice was accepted. In sum, the current findings extended previous research findings by showing that the effect of advisees' facial expressions on the advisors' advice-giving existed in multiple stages, including both the feedback evaluation stage and the advice decision stage.

Abstract
Recent research suggests that exposure to monetary cues strengthens an individual's motivation to pursue monetary rewards by inducing the 'market mode' (i.e. thinking and behaving in accordance with market principles). Here, we examined the effect of market mode on social reward processes by means of event-related potentials (ERPs). Participants primed with monetary images or neutral images acted as advisors who selected one of two options for a putative advisee. Subsequently, all participants passively observed the advisee accepting or rejecting their advice and receiving a gain or loss outcome. After money priming, the feedback-related negativity (FRN) to the advisee's gain/loss outcome was larger following incorrect as compared to correct advice irrespective of whether the advice had been accepted or rejected. A smaller P3 following incorrect advice showed only when the advice was rejected. After neutral priming, the FRN was larger for incorrect relative to correct advice only when the advice had been rejected. However, the P3 was larger for correct relative to incorrect advice irrespective of the advisee's final choice. These findings suggest that the market mode facilitates early and automatic feedback processing but reduces later and controlled responding to outcomes that had been accepted.
