Intergroup bias

Racial biases, facial trustworthiness, and resting heart rate variability: unravelling complexities in pain recognition

The study explores whether racial identity and appearance-based trustworthiness judgments can affect recognition of pain in medical students differing in levels of resting heart rate variability (HRV), a measure of parasympathetic control of the heart. After undergoing HRV assessment, 68 medical students (37 females) participated in a dynamic pain recognition task, viewing video clips of White and Black faces, which differed in perceived trustworthiness based on facial appearance, transitioning from neutral to intense pain expressions. Response time, pain intensity attribution and treatment recommendations were analyzed. Pain was recognized slower and estimated as less intense in Black compared to White faces, leading to a lower likelihood of recommending therapy. Pain recognition was faster for untrustworthy-looking White faces compared to trustworthy ones, while perceived trustworthiness had a minimal impact on the speed of pain recognition in Black faces. However, untrustworthy-looking faces were estimated to express more pain, particularly for Black faces. Notably, these biases were more pronounced in individuals with low, rather than high, resting HRV. Considering that therapeutic decisions mirrored pain intensity attribution, it would be important to increase awareness of these biases during medical training in order to promote equity in future pain assessment and treatment.

Does Mindfulness Improve Intergroup Bias, Internalized Bias, and Anti-Bias Outcomes?: A Meta-Analysis of the Evidence and Agenda for Future Research

Whereas mindfulness has been shown to enhance personal well-being, studies suggest it may also benefit intergroup dynamics. Using an integrative conceptual model, this meta-analysis examined associations between mindfulness and (a) different manifestations of bias (implicit/explicit attitudes, affect, behavior) directed toward (b) different bias targets (outgroup or ingroup, e.g., internalized bias), by (c) intergroup orientation (toward bias or anti-bias). Of 70 samples, 42 (N = 3,229) assessed mindfulness-based interventions (MBIs) and 30 (N = 6,002) were correlational studies. Results showed a medium-sized negative effect of MBIs on bias outcomes, g = -0.56, 95% confidence interval [-0.72, -0.40]; I(2;3)2: 0.39; 0.48, and a small-to-medium negative effect between mindfulness and bias for correlational studies, r = -0.17 [-0.27, -0.03]; I(2;3)2: 0.11; 0.83. Effects were comparable for intergroup bias and internalized bias. We conclude by identifying gaps in the evidence base to guide future research.

The impact of group membership on punishment versus partner rejection

People often display ingroup bias in punishment, punishing outgroup members more harshly than ingroup members. However, the impact of group membership may be less pronounced when people are choosing whether to stop interacting with someone (i.e., partner rejection). In two studies (N = 1667), we investigate the impact of group membership on both response types. Participants were assigned to groups based on a "minimal" groups paradigm (Study 1) or their self-reported political positions (Study 2) and played an incentivized economic game with other players. In this game, participants (Responders) responded to other players (Deciders). In the Punishment condition, participants could decrease the Decider's bonus pay. In the Partner Rejection condition, participants could reject future interactions with the Decider. Participants played once with an ingroup member and once with an outgroup member. To control for the effects of intent and outcome, scenarios also differed based on the Decider's Intent (selfish versus fair) and the Outcome (equal versus unequal distribution of resources). Participants punished outgroup members more than ingroup members, however group membership did not influence decisions to reject partners. These results highlight partner rejection as a boundary condition for the impact of group on responses to transgressions.

Bias intervention messaging in student evaluations of teaching: The role of gendered perceptions of bias

Many studies have documented discrepancies in student evaluation of teaching ratings between male and female instructors and between ethnic majority and minority instructors. Given the importance of such ratings to academic careers and the likelihood of potential intergroup bias, it is crucial that institutions consider approaches to mitigate such biases. Several recent studies have found that simple bias mitigation messaging can be effective in reducing gender and other biases. In the present research, students enrolled in several large Faculty of Science undergraduate courses at an Australian university were recruited on a volunteer basis via the course learning management system. Half of the participants were randomly assigned an intervention message highlighting potential biases relating to gender and language background. Data from 185 respondents were analysed using Bayesian ordinal regression models assessing the impact of message exposure on evaluation scores. Reading a bias intervention message caused students to significantly adjust their scores, with the nature of that change dependent on student and instructor characteristics. Among male students, the bias intervention message significantly increased scores for all except male instructors with English speaking backgrounds, for whom there was no significant impact of the message. In contrast, among female students, the bias intervention message significantly decreased scores for male instructors with English speaking backgrounds only. The sample showed an overall decrease in scores in the intervention group relative to the control group. This is the first study to detect a negative impact of bias intervention messaging on SET scores. Our results suggest students may not acknowledge their own potential bias towards instructors with whom they share similar demographic backgrounds. In conclusion, bias intervention messaging may be a simple method of mitigating bias, but it may lead to consequences in which one or more groups receive lower ratings as a result of the correction.

Empathy arousal and emotional reactions to victims of the gender pay gap

Men and women are well aware of the gender pay gap. The present study involved four experiments (N = 341, student sample, N = 203 general population sample) in which we indirectly measured empathy by asking participants to rate the non-complex and complex emotions they felt when reading a scenario in which a woman described her pay situation. Experiments 1 (equal pay vs. unequal pay) and 2, 3 & 4 (angry vs. depressed reaction to pay inequality) investigate differences in empathy arousal between men and women by assessing their emotions. Globally, both men and women identified correctly emotions expressed by the women victim of pay inequity. On complex emotions, women express more other suffering emotions than men, only in Experiment 4. Coupled with expression of guilt/shame for men only, these results are discussed in the perspective of future research.

Psych Unit Gangs: An Autoethnography

The stigma against people with mental illness is a well-worn subject; however, stigma between groups of people with different mental illnesses is rarely discussed. Within the context of a psychiatric hospital, hierarchies form among patients based on symptomatology and diagnosis. In this perspectives piece, I explore, how, in my experiences with being on the bottom of this hierarchy as a person with a schizophrenia-spectrum psychotic illness in a psychiatric hospital. I, and my fellow "psychotics," were stigmatized and outcasted by other groups of individuals who were diagnosed with mental illnesses that are considered less serious than psychosis. I explore how one stigmatized, outcasted group (people with substance use and mood disorders) construct power relationships over an even more highly stigmatized, marginalized group (people with psychotic disorders). Utilizing Goffmanian and Tajfel theories, the perspective explores stigma within a total institution, and the formation of in-groups and out-groups. I explore how people, upon entering the psychiatric hospital unit, know almost immediately whether they belong to the dominant group or the subordinate group, and I conclude with recommendations to reduce the stigma of psychotic disorders within popular culture.

Morality, Social Inclusion, and In-Group Superiority: The Differential Role of Individualizing and Binding Foundations in Perceptions of the Social Identity of In-Group and Out-Group Members

Research into social identity and morality judgments typically focuses on how the former influences the latter. We approach this theme from the opposite direction, establishing the influence of morality on perceptions of social identity. In three studies, conducted in two cultures, we show that in-group members acting immorally are excluded from the group. Extending this investigation to the overlooked study of out-group-on-out-group behavior, in Studies 2 and 3, we compare perceptions of social inclusion for in-group members following (im)moral behavior toward the in-group with perceptions of out-group members following (im)moral behavior toward the out-group. We show that people treat in-group and out-group members alike with respect to binding morals, which concern preservation and protection of the group, but not individualizing morals, which concern preservation and protection of individual rights. Finally, in Study 3, we confirm the underlying motivating mechanism of reasserting in-group superiority by affirming the positive distinctiveness of one's own group.

Impacts of Racial and Gender Identities on Individuals' Intentions to Seek a Counselor

To understand the theoretical impact of racial and gender identities on counselor selection, an online experiment was conducted with 527 participants in which both the race and gender of a perspective counselor's online profile were manipulated. Results showed that participants had a higher intention to seek counseling when the counselor was from the same racial and/or gender group. These preferences existed above and beyond other identity-based evaluative metrics, such as those tied to group stereotypes (e.g., warmth and competence). The results advocate for the development and evaluation of culturally tailored digital health interventions and underscore the importance of further formative research in this area to enhance the accessibility and effectiveness of healthcare resources for all.

Exemplary Self-Discipline, Leniency towards Others: Competitive Contexts Amplify the "Black Sheep Effect" in Restoring Ingroup Trust

Intergroup interaction, a pivotal aspect of social interaction, encompasses both cooperation and competition. Group identity significantly impacts individual behaviors and decision-making processes. This influence manifests in two contrasting ways when addressing rule-breaking by interaction partners: in-group favoritism, where individuals are more lenient towards infractions committed by in-group members, and the black sheep effect, where in-group members are penalized for their rule-breaking. Although trust is crucial in intergroup interactions, the precise impact of group identity on trust restoration and the potential moderating role of intergroup interaction types remain to be elucidated. This study presents two experiments designed to explore these dynamics. In Study 1, the manipulation of group identity through a point estimation task was utilized to evaluate its impact on intergroup trust restoration via a series of repeated trust games. Study 2 aimed to explore the moderating role of intergroup interaction on intergroup trust restoration by contrasting cooperation and competition situations. The results uncovered a "black sheep effect", where participants demonstrated a greater propensity for trust restoration with out-group members than with in-group members. This effect, however, was only evident in competitive contexts. Conversely, in cooperative contexts, the individual's trust in the in-group and out-group members is effectively repaired. These findings contribute to a deeper comprehension of trust dynamics in intergroup interactions, promoting trust establishment and repair between diverse groups, thereby boosting team collaboration efficiency and mitigating conflicts.

The cross-cultural adaptation of Chinese international students: an empirical study on sequential-mediated effects

Using convenience sampling and snowball sampling methods, data from 432 Chinese international students in 10 countries, including the United Kingdom, South Korea, and the United States, were collected to construct a multivariate sequential-mediated mixed model for cross-cultural adaptation. SPSS 23.0 and AMOS 23.0 were employed for aggregated validity, discriminant validity, and sequential-mediated effects analysis. The study found that: Cultural adaptation stress is negatively correlated with positive coping and positively correlated with negative coping, with negative coping having a significant negative impact during the cross-cultural adaptation process. Positive coping is positively correlated with sports participation, while negative coping is negatively correlated with sports participation. Sports participation is positively associated with in-group identification and negatively associated with out-group bias. In-group identification has a positive impact on cross-cultural adaptation, whereas out-group bias cannot effectively predict cross-cultural adaptation.

Can't Live With Them, Can't Live Without Them: The Ambivalent Effects of Existential Outgroup Threat on Helping Behavior

Social comparison theories suggest that ingroups are strengthened whenever important outgroups are weakened (e.g., by losing status or power). It follows that ingroups have little reason to help outgroups facing an existential threat. We challenge this notion by showing that ingroups can also be weakened when relevant comparison outgroups are weakened, which can motivate ingroups to strategically offer help to ensure the outgroups' survival as a highly relevant comparison target. In three preregistered studies, we showed that an existential threat to an outgroup with high (vs. low) identity relevance affected strategic outgroup helping via two opposing mechanisms. The potential demise of a highly relevant outgroup increased participants' perceptions of ingroup identity threat, which was positively related to helping. At the same time, the outgroup's misery evoked schadenfreude, which was negatively related to helping. Our research exemplifies a group's secret desire for strong outgroups by underlining their importance for identity formation.

The Formation of Negative Attitudes Toward Novel Groups

People perceive out-groups, minorities, and novel groups more negatively than in-groups, majorities, and familiar groups. Previous research has argued that such intergroup biases may be caused by the order in which people typically encounter social groups. Groups that are relatively novel to perceivers (e.g., out-groups, minorities) are primarily associated with distinct attributes that differentiate them from familiar groups. Because distinct attributes are typically negative, attitudes toward novel groups are negatively biased. Five experiments (N = 2,615 adults) confirmed the generalizability of the novel groups' disadvantage to different aspects of attitude formation (i.e., evaluations, memory, stereotyping), to cases with more than two groups, and to cases in which groups were majority/minority or in-groups/out-groups. Our findings revealed a remarkably robust influence of learning order in the formation of group attitudes, and they imply that people often perceive novel groups more negatively than they actually are.

Electrophysiological indexes of ingroup bias in a group Stroop task: Evidence from an event-related potential study

Although cognitive system assigns higher attentional resources to ingroup information than outgroup information, but it is unclear whether the ingroup bias can be measured by the processes that are related to allocation of attentional resources to ingroup information. Thus, a group Stroop task was developed to study the issues combining with event-related potential (ERP) technique in this study. Specifically, 34 subjects (17 female, mean age = 20.76 ± 1.26) were firstly divided into blue or red group (17 subjects for each group); then they were asked to categorize four words of Stroop task into "our team" or "other team" based on the ink color (blue/red) of the words whose meaning were also red/blue. The behavioral results showed that outgroup ink color processing was interfered by ingroup word meaning, but the ingroup ink color processing was less/not interfered by outgroup word meaning. The ERP results showed that the amplitude of frontal N100 was enhanced when more attentional resources were automatically captured by ingroup information in early stage than outgroup information; P2/N2 amplitude was reduced or enhanced when outgroup information processing was interfered by ingroup information; enhanced P3b amplitude reflected that attention could be more easily allocated to ingroup information than outgroup information based on target. This study implied a novel direction to study the neural basis of ingroup bias by investigating the roles of ingroup bias in assigning attentional resources to group information.

How Can Debiasing Research Aid Efforts to Reduce Discrimination?

PUBLIC ABSTRACT

Scientists studying intergroup biases are often concerned with lessening discrimination (unequal treatment of one social group versus another), but many interventions for reducing such biased behavior have weak or limited evidence. In this review article, we argue one productive avenue for reducing discrimination comes from adapting interventions in a separate field-judgment and decision-making-that has historically studied "debiasing": the ways people can lessen the unwanted influence of irrelevant information on decision-making. While debiasing research shares several commonalities with research on reducing intergroup discrimination, many debiasing interventions have relied on methods that differ from those deployed in the intergroup bias literature. We review several instances where debiasing principles have been successfully applied toward reducing intergroup biases in behavior and introduce other debiasing techniques that may be well-suited for future efforts in lessening discrimination.

Reading of ingroup politicians' smiles triggers smiling in the corner of one's eyes

Spontaneous smiles in response to politicians can serve as an implicit barometer for gauging electorate preferences. However, it is unclear whether a subtle Duchenne smile-an authentic expression involving the coactivation of the zygomaticus major (ZM) and orbicularis oculi (OO) muscles-would be elicited while reading about a favored politician smiling, indicating a more positive disposition and political endorsement. From an embodied simulation perspective, we investigated whether written descriptions of a politician's smile would trigger morphologically different smiles in readers depending on shared or opposing political orientation. In a controlled reading task in the laboratory, participants were presented with subject-verb phrases describing left and right-wing politicians smiling or frowning. Concurrently, their facial muscular reactions were measured via electromyography (EMG) recording at three facial muscles: the ZM and OO, coactive during Duchenne smiles, and the corrugator supercilii (CS) involved in frowning. We found that participants responded with a Duchenne smile detected at the ZM and OO facial muscles when exposed to portrayals of smiling politicians of same political orientation and reported more positive emotions towards these latter. In contrast, when reading about outgroup politicians smiling, there was a weaker activation of the ZM muscle and no activation of the OO muscle, suggesting a weak non-Duchenne smile, while emotions reported towards outgroup politicians were significantly more negative. Also, a more enhanced frown response in the CS was found for ingroup compared to outgroup politicians' frown expressions. Present findings suggest that a politician's smile may go a long way to influence electorates through both non-verbal and verbal pathways. They add another layer to our understanding of how language and social information shape embodied effects in a highly nuanced manner. Implications for verbal communication in the political context are discussed.

A psycholinguistic study of intergroup bias and its cultural propagation

Intergroup bias is the tendency for people to inflate positive regard for their in-group and derogate the out-group. Across two online experiments (N = 922) this study revisits the methodological premises of research on language as a window into intergroup bias. Experiment 1 examined (i) whether the valence (positivity) of language production differs when communicating about an in- vs. out-group, and (ii) whether the extent of this bias is influenced by the positivity of input descriptors that were initially presented to participants as examples of how an in-group or out-group characterize themselves. Experiment 2 used the linear diffusion chain method to examine how biases are transmitted through cultural generations. Valence of verbal descriptions were quantified using ratings obtained from a large-scale psycholinguistic database. The findings from Experiment 1 indicated a bias towards employing positive language in describing the in-group (exhibiting in-group favoritism), particularly in cases where the input descriptors were negative. However, there was weak evidence for increased negativity aimed at the out-group (i.e., out-group derogation). The findings from Experiment 2 demonstrated that in-group positivity bias propagated across cultural generations at a higher rate than out-group derogation. The results shed light on the formation and cultural transmission of intergroup bias.

How retributive motives shape the emergence of third-party punishment across intergroup contexts

This study examines how retributive motives-the desire to punish for the purpose of inflicting harm in the absence of future benefits-shape third-party punishment behavior across intergroup contexts. Six- to nine-year-olds (N = 151, Mage = 8.00, SDage = 1.15; 54% White, 18% mixed ethnicities, 17% Asian American; 46% female; from the USA) could punish ingroup, outgroup, or non-group transgressors by removing positive resources and allocating negative ones. Both punishments were described as retributive, yet allocating negative resources was perceived as more retributive than removing positive ones. We predicted that children would punish outgroups more so than ingroups and that this effect would be especially pronounced when punishment is perceived as particularly retributive. The results did not align with this prediction; instead, children similarly punished all agents.

Exaggerating differences back and forth: Two levels of intergroup accentuation

Social perceivers tend to exaggerate existing differences between groups, a phenomenon known as intergroup accentuation. In two preregistered experiments, we tested the hypothesis that accentuation originates in the initial learning of information about a novel group. In both experiments, perceivers exaggerated differences between two fictitious social groups that differed probabilistically in two dimensional traits. As hypothesized, accentuation was stronger for the group encountered second, confirming that accentuation originates partly in processes operating during the acquisition of group information. However, accentuation was also robust for the group encountered first, suggesting that it also occurs 'backward' even when group learning was unbiased. We discuss implications for stereotype formation generally and the perception of social minorities and out-groups specifically. As these groups are often encountered second in social reality, stereotypes of them might be particularly polarized.

The association between political identity centrality and cancelling proclivity

Augmented by the rise of social media, contemporary culture has increasingly witnessed the phenomenon of "cancellation" - that is, a brand's swift and public fall from grace, catalyzed through digital platforms like Twitter and, in turn, traditional media. We are the first to examine individual difference predictors of cancelling proclivity. We explore the relationship between a novel individual difference, political identity centrality (the extent to which one's political identity [e.g., liberal, conservative] is central to self-concept), and individuals' propensity to seek retribution from a moral transgressor online (i.e., their "cancelling proclivity"). Additionally, we test the mediating roles of individual differences in moral exporting (actively promoting and supporting the proliferation of one's own moral beliefs), social vigilantism (the tendency of individuals to impress and propagate their "superior" beliefs onto "ignorant" others), virtue signaling (signaling one's virtuousness for public respect or admiration), and self-efficacy on the relationship between political identity centrality and cancelling proclivity. Using an online panel (n = 459), we uncover that political identity centrality is significantly and positively associated with cancelling proclivity operationalized as reaction strength to transgressions and calling-out (calling attention to a transgression) and piling-on a transgressor (mass public prolific addition of comments about the transgression and transgressor). Interestingly while both virtue signaling and social vigilantism were found to be significant mediators, they played distinct roles wherein virtue signaling mediates the relationship for strength of reaction to transgressions, and social vigilantism mediates the relationship for calling-out and piling-on. The current research illustrates that some individual behavior may be less about what someone believes and rather the importance of those beliefs to one's identity - a valuable insight not previously identified in the literature. We discuss theoretical contributions, implications for future research, and applied implications (e.g., how brands might recover from cancellations).

The Wisdom of the Crowd is not a Forgone Conclusion. Effects of Self-Selection on (Collaborative) Knowledge Construction

Web 2.0 has elevated the possibilities of collaboration to unprecedented levels. Therein lies great potential, as the aptly coined phenomenon "Wisdom of the Crowd" implies. When it comes to controversial topics, however, there is no safety in numbers alone. On the contrary, collaboration among only like-minded people may even exacerbate biases (e.g., Echo Chambers). Yet, it is human nature to seek out like-minded others. Consequently, the process of self-selection is crucial if the heterogeneity of opinions serves as a safeguard against undesirable effects of group processes (e.g., attitude polarization). Accordingly, online environments that invite more heterogeneous (vs. homogeneous) users should produce less biased content. We tested this hypothesis in a field study, comparing articles on the same 20 controversial topics from the online encyclopedias Conservapedia and RationalWiki with Wikipedia (and Britannica serving as a gold standard) and exploring the opinions of discussants in the three online encyclopedias. As expected, articles from Conservapedia and RationalWiki were significantly less balanced than articles from Wikipedia and Britannica. We replicated this finding in a lab study with 257 participants who self-selected to one of three online wikis (Vegan Love, Nutrition, Meat & Fish) and individually as well as collaboratively wrote an encyclopedia-like article about "Diets." As expected, Wikis with a specific focus (Vegan Love, Meat & Fish) predominantly attracted authors with a positive attitude toward this focus and, as a consequence, resulted in more biased content than in the Nutrition Wiki. Overall, our results suggest that crowds alone do not guarantee wisdom-self-selection is a crucial process that needs to be taken into account.

Determinants of automatic age and race bias: ingroup-outgroup distinction salience moderates automatic evaluations of social groups

Introduction

The present research investigates whether ingroup-outgroup distinction salience moderates automatic intergroup bias (i.e., more positive evaluations of ingroup targets relative to outgroup targets) toward multiply categorizable social targets.

Methods

In two experiments, we manipulated the salience of participants' social identity based on age vs. race, respectively. Afterwards, we measured automatic evaluations of social targets varying in age and race.

Results

Young White participants exhibited higher automatic race bias when their racial identity (i.e., White in contrast to Black) was salient. Conversely, they exhibited higher automatic age bias when their age identity (i.e., young in contrast to old) was salient.

Discussion

Going beyond previous research, we show that it is sufficient to direct participants' attention to their ingroup-identity in contrast to the respective outgroup to cause changes in automatic intergroup bias. This is important because it provides a strong test of the hypothesis that ingroup-outgroup distinction salience moderates automatic intergroup bias.

Facial trustworthiness dampens own-gender bias in emotion recognition

Previous research suggests that emotion recognition is influenced by social categories derived by invariant facial features such as gender and inferences of trustworthiness from facial appearance. The current study sought to replicate and extend these findings by examining the intersection of these social categories on recognition of emotional facial expressions. We used a dynamic emotion recognition task to assess accuracy and response times in the happiness and anger categorization displayed by female and male faces that differed in the degree of facial trustworthiness (i.e., trustworthy- vs. untrustworthy-looking faces). We found that facial trustworthiness was able to modulate the own-gender bias on emotion recognition, as responses to untrustworthy-looking faces revealed a bias towards ingroup members. Conversely, when faces look trustworthy, no differences on emotion recognition between female and male faces were found. In addition, positive inferences of trustworthiness lead to faster recognition of happiness in females and anger in males, showing that facial appearance was able to influence also the intersection between social categories and specific emotional expressions. Together, these results suggest that facial appearance, probably due to the activation of approach or avoidance motivational systems, is able to modulate the own-gender bias on emotion recognition.

Focusing attention on others' negative emotions reduces the effect of social relationships on children's distributive behaviors

The present study investigates whether directing five- to six-year-old children's attention to hypothetical resource recipients that included familiar and non-familiar people would affect their favoritism toward a familiar person, as reflected in how they allocated resources. In Experiment 1, we instructed participants to give one of several stickers to another person or keep all the stickers for themselves. Under the control conditions, participants more frequently gave stickers to friends than to non-friends. However, when asked about others' emotions, they distributed stickers equally among friends and non-friends. Therefore, focusing on others' thoughts reduced participants' favoritism toward friends. Experiment 2 tested whether focusing on both emotional valences would affect favoritism toward a familiar person, as reflected in children's resource distribution choices. Experiment 2 was identical to Experiment 1, except we asked participants about the other person's emotional valence. When asked about others' negative emotions, participants distributed the stickers equally between themselves and others. However, when asked about others' positive emotions, they distributed more stickers to friends than to non-friends. Neither others' emotional valence nor group status affected the perceived intensity of their emotion or the participant's emotional state. These results suggest that children's favoritism toward friends can be reduced by encouraging them to think about others' negative emotional states.

The Effect of Group Identity on Chinese College Students' Social Mindfulness: Testing a Moderated Mediation Model

Purpose

The current study examined the effect of group identity on social mindfulness, how awe mediates this effect, and lastly how empathy may moderate the various indirect pathway.

Methods

A total of 2041 Chinese college students were recruited from different universities or colleges to complete the questionnaire including group identity scale, awe scale, empathy scale and social mindfulness scale. This study was conducted using random and convenient sampling, as well as SPSS and its plugin PROCESS as a statistical tool.

Results

The present study showed that group identity was positively associated with awe and social mindfulness. Awe was positively associated with social mindfulness. Empathy further moderated the relationship between group identity and awe, awe and social mindfulness, as well as group identity and social mindfulness.

Conclusion

The findings of this study shed light on a correlation between group identity and social mindfulness. Furthermore, this study emphasizes the practical importance of intervening in the empathy level of students who have poor empathy in order to increase their social mindfulness.

Knowledge Transfer Within Organizations: Mechanisms, Motivation, and Consideration

Knowledge transfer-the extent to which one unit learns from or is affected by the experience of another-has the potential to improve the performance of organizations. Through knowledge transfer, developments made in one unit of an organization can benefit others. Studies have found, however, considerable variation in the extent to which knowledge transfers across organizational units. In some cases, knowledge transfers seamlessly, whereas in others, knowledge transfer is far from complete. This article reviews research with the aim of explaining the variation observed in knowledge transfer. Key factors identified as explaining the variation include knowledge transfer opportunities, knowledge characteristics, mechanisms for knowledge transfer, motivation for transfer, and the depth of consideration of knowledge. These factors are integrated into a theoretical framework that predicts when knowledge transfer will be successful. The article concludes with a discussion of directions for future research to increase our understanding of knowledge transfer in organizations.

Impediments to peace

While effective institutional practices are critical for the evolution of peace certain factors deter their effectiveness. In-group and out-group dynamics may make peace difficult between culturally distinct groups. Critical ecological conditions often lead to intractable conflict over resources. And within group conflicts of interest most prominently between generations may inhibit effective peace making.

Less Negative Implicit Attitudes Toward Autism Spectrum Disorder in University Students: A Comparison with Physical Disabilities

People with autism spectrum disorder (ASD) experience stigmatization rooted in negative attitudes or prejudice toward them due to social awkwardness. However, little is known about implicit attitudes toward ASD, especially differences in attitudes compared to those of more visible conditions; physical disabilities. In this study, we implemented implicit association tests (IATs) to assess implicit attitudes. Sixty-three university students participated in IATs and answered questionnaires that measured explicit attitudes, social desirability, knowledge about-and familiarity with-disorders. The results demonstrated that implicit attitude toward ASD was significantly less negative than toward physical disabilities. Regarding the discrepancy, not socially awkward behavior but appearance of people with ASD can be evaluated as 'in-group' members and lead to less negative attitude compared with physical disabilities.

Sadism in the context of intergroup aggression

People more readily harm members of outgroups than ingroups, often enjoying the inflicted agony. Yet it remains unclear how these malevolent tendencies towards outgroups relate to sadism. Sadists often harm others, driven by a desire to feel pleasure from their suffering. In attempt to bridge these two lines of research, this work examined relationships between sadism and aggression against ingroup and outgroup members in three studies (total N = 755) that focused on two groups with a history of conflict (i.e., the United Kingdom and the Republic of Ireland). Across all studies, British participants' sadistic tendencies were just as strongly linked to their aggression against ingroup members (i.e., British partners) as to their aggression against outgroup members (i.e., Irish partners). Despite this lack of a preference for greater outgroup aggression, they tended to enjoy outgroup aggression more than ingroup aggression, especially at its extreme levels. These findings extend works linking sadism to aggression into the domain of intergroup relations and bind together research on sadism and intergroup schadenfreude.

Joint action with human and robotic co-actors: Self-other integration is immune to the perceived humanness of the interacting partner

When performing a joint action task, we automatically represent the action and/or task constraints of the co-actor with whom we are interacting. Current models suggest that, not only physical similarity, but also abstract, conceptual features shared between self and the interacting partner play a key role in the emergence of joint action effects. Across two experiments, we investigated the influence of the perceived humanness of a robotic agent on the extent to which we integrate the action of that agent into our own action/task representation, as indexed by the Joint Simon Effect (JSE). The presence (vs. absence) of a prior verbal interaction was used to manipulate robot's perceived humanness. In Experiment 1, using a within-participant design, we had participants perform the joint Go/No-go Simon task with two different robots. Before performing the joint task, one robot engaged in a verbal interaction with the participant and the other robot did not. In Experiment 2, we employed a between-participants design to contrast these two robot conditions as well as a human partner condition. In both experiments, a significant Simon effect emerged during joint action and its amplitude was not modulated by the humanness of the interacting partner. Experiment 2 further showed that the JSE obtained in robot conditions did not differ from that measured in the human partner condition. These findings contradict current theories of joint action mechanisms according to which perceived self-other similarity is a crucial determinant of self-other integration in shared task settings.

A research agenda for understanding how social inequality is linked to brain structure and function

Consistent evidence documents powerful effects of social inequality on health, well-being and academic achievement. Yet research on whether social inequality may also be linked to brain structure and function has, until recently, been rare. Here we describe three methodological approaches that can be used to study this question-single site, single study; multi-site, single study; and spatial meta-analysis. We review empirical work that, using these approaches, has observed associations between neural outcomes and structural measures of social inequality-including structural stigma, community-level prejudice, gender inequality, neighbourhood disadvantage and the generosity of the social safety net for low-income families. We evaluate the relative strengths and limitations of these approaches, discuss ethical considerations and outline directions for future research. In doing so, we advocate for a paradigm shift in cognitive neuroscience that explicitly incorporates upstream structural and contextual factors, which we argue holds promise for uncovering the neural correlates of social inequality.

Social identity bias and communication network clustering interact to shape patterns of opinion dynamics

Social influence aligns people's opinions, but social identities and related in-group biases interfere with this alignment. For instance, the recent rise of young climate activists (e.g. 'Fridays for Future' or 'Last Generation') has highlighted the importance of generational identities in the climate change debate. It is unclear how social identities affect the emergence of opinion patterns, such as consensus or disagreement, in a society. Here, we present an agent-based model to explore this question. Agents communicate in a network and form opinions through social influence. The agents have fixed social identities which involve homophily in their interaction preferences and in-group bias in their perception of others. We find that the in-group bias has opposing effects depending on the network topology. The bias impedes consensus in highly random networks by promoting the formation of echo chambers within social identity groups. By contrast, the bias facilitates consensus in highly clustered networks by aligning dispersed in-group agents across the network and, thereby, preventing the formation of isolated echo chambers. Our model uncovers the mechanisms underpinning these opposing effects of the in-group bias and highlights the importance of the communication network topology for shaping opinion dynamics.

Network Analysis of Sexual Sensation Seeking, Internalized Homophobia, and Social Norms Among Men Who Have Sex with Men with Different Sexual Partner Types

Men who have sex with men (MSM) are at disproportionate risk for developing sexually transmitted infections (STIs) such as HIV. Understanding the relationships among factors related to risky sexual behaviors, such as internalized homophobia, sexual sensation seeking, and individual and community norms, among MSM with different sexual partner types may contribute to designing targeted interventions for reducing risky sexual behaviors and STI transmission. We conducted a cross-sectional study recruiting 781 MSM in Sichuan Province, China. All participants were divided into groups with and without sexual partners, groups with regular and casual sexual partners, and groups with only male and both male and female partners in the past 6 months. Network analysis was used to analyze the relationships among dimensions of self-reported sexual sensation seeking, internalized homophobia, and social norms in different groups. Of 781 MSM, 606 (77.6%) had sexual partners in the past 6 months, and among these participants, 429 (70.8%) had casual sexual partners, and 103 (17.0%) had both male and female sexual partners. The complex and intensive relationships between dimensions were mainly observed in networks of MSM with any type of sexual partners, with individual norms (dimension of social norms) presenting strongly negative relationships with fresh feeling (dimension of sexual sensation seeking) and homosexuality morality (dimension of internalized homophobia). One dimension of sexual sensation seeking (i.e., fresh feeling) and two dimensions of internalized homophobia (i.e., homosexuality morality and self-identification) were relatively central variables in most groups, especially for those with casual sexual partners. Our study highlights the role of individual norms in restraining sensation seeking, internalized homophobia, especially among MSM with sexual partners. Intervention targeting these central variables may contribute to reduced risky sexual behaviors and further slow the spread of STIs in MSM.

Resource scarcity aggravates ingroup bias: Neural mechanisms and cross-scenario validation

Previous studies examining the relationship between ingroup bias and resource scarcity have produced heterogeneous findings, possibly due to their focus on the allocation of positive resources (e.g. money). This study aims to investigate whether ingroup bias would be amplified or eliminated when perceived survival resources for counteracting negative stimuli are scarce. For this purpose, we exposed the participants and another confederate of the experimenters (ingroup/outgroup member) to a potential threat of unpleasant noise. Participants received some 'relieving resources' to counteract noise administration, the amount of which may or may not be enough for them and the confederate in different conditions (i.e. abundance vs. scarcity). First, a behavioural experiment demonstrated that intergroup discrimination manifested only in the scarcity condition; in contrast, the participants allocated similar amounts of resource to ingroup and outgroup members in the abundance condition, indicating a context-dependent allocation strategy. This behavioural pattern was replicated in a follow-up neuroimaging experiment, which further revealed that when contrasting scarcity with abundance, there was higher activation in the anterior cingulate cortex (ACC) as well as stronger functional connectivity of the ACC with the empathy network (including the temporoparietal junction and medial prefrontal cortex) for ingroup compared to outgroup members. We suggest that ACC activation reflects the mentalizing process toward ingroup over outgroup members in the scarcity condition. Finally, the ACC activation level significantly predicted the influence of resource scarcity on ingroup bias in hypothetical real-life situations according to a follow-up examination.

Toward Parsimony in Bias Research: A Proposed Common Framework of Belief-Consistent Information Processing for a Set of Biases

One of the essential insights from psychological research is that people's information processing is often biased. By now, a number of different biases have been identified and empirically demonstrated. Unfortunately, however, these biases have often been examined in separate lines of research, thereby precluding the recognition of shared principles. Here we argue that several-so far mostly unrelated-biases (e.g., bias blind spot, hostile media bias, egocentric/ethnocentric bias, outcome bias) can be traced back to the combination of a fundamental prior belief and humans' tendency toward belief-consistent information processing. What varies between different biases is essentially the specific belief that guides information processing. More importantly, we propose that different biases even share the same underlying belief and differ only in the specific outcome of information processing that is assessed (i.e., the dependent variable), thus tapping into different manifestations of the same latent information processing. In other words, we propose for discussion a model that suffices to explain several different biases. We thereby suggest a more parsimonious approach compared with current theoretical explanations of these biases. We also generate novel hypotheses that follow directly from the integrative nature of our perspective.

Neural mechanisms underlying interindividual differences in intergenerational sustainable behavior

Intergenerational sustainability is a pressing challenge, which is exacerbated by the fact that the current generation must make sacrifices today to ensure the well-being of future generations. There are large interindividual differences in intergenerational sustainable behavior. However, the neural mechanisms underlying these interindividual differences have remained unexplored. Here, we combined fMRI with a consequential intergenerational sustainability paradigm in a sample of 72 healthy students. Specifically, we analyzed task-dependent functional activity and connectivity during intergenerational sustainable decision-making, focusing on the state-like neurophysiological processes giving rise to behavioral heterogeneity in sustainability. We found that differences in neural communication within and between the mentalizing (TPJ/DMPFC) and cognitive control (ACC/DLPFC) network are related to interindividual differences in intergenerational sustainable behavior. Specifically, the stronger the functional connectivity within and between these networks during decision-making, the more individuals behaved intergenerationally sustainably. Corroborated by mediation analyses, these findings suggest that differences in the engagement of perspective-taking and self-control processes underly interindividual differences in intergenerational sustainable behavior. By answering recent calls for leveraging behavioral and neuroscience for sustainability research, we hope to contribute to interdisciplinary efforts to advance the understanding of interindividual differences in intergenerational sustainability.

Political orientation, trust and discriminatory beliefs during the COVID-19 pandemic: Longitudinal evidence from the United Kingdom

The COVID-19 pandemic has impacted the world in many ways; for example, evidence from the United Kingdom indicates that higher rates of discriminatory behaviours against immigrants have been recorded during this period. Prior research suggests that political orientation and trust are instrumental in discriminatory beliefs against immigrants. A longitudinal study (six waves and a follow-up) was conducted in the United Kingdom during the COVID-19 pandemic (September 2020-August 2021) using convenience sampling (N = 383). The hypotheses enquired about whether political orientation predicts trust in government, trust in science and discriminatory beliefs. Multilevel regression and mediation analyses were conducted, using repeated measures nested within individuals. It was found that conservative views are associated with higher discriminatory beliefs, lower trust in science and higher trust in government. Furthermore, trust in science promotes reduction of discrimination, whereas trust in government, increases discriminatory beliefs. However, a nuance revealed by an interaction effect, shows that a positive alignment between political and scientific authorities may be required to reduce prejudice against immigrants. Exploratory multilevel mediation showed that trust is a mediator between political orientation and discriminatory beliefs.

Partner similarity and social cognitive traits predict social interaction success among strangers

Social interactions are a ubiquitous part of engaging in the world around us, and determining what makes an interaction successful is necessary for social well-being. This study examined the separate contributions of individual social cognitive ability and partner similarity to social interaction success among strangers, measured by a cooperative communication task and self-reported interaction quality. Sixty participants engaged in a 1-h virtual social interaction with an unfamiliar partner (a laboratory confederate) including a 30-min cooperative 'mind-reading' game and then completed several individual tasks and surveys. They then underwent a separate functional MRI session in which they passively viewed video clips that varied in content. The neural responses to these videos were correlated with those of their confederate interaction partners to yield a measure of pairwise neural similarity. We found that trait empathy (assessed by the interpersonal reactivity index) and neural similarity to partner both predicted communication success in the mind-reading game. In contrast, perceived similarity to partner and (to a much lesser extent) trait mind-reading motivation predicted self-reported interaction quality. These results highlight the importance of sharing perspectives in successful communication as well as differences between neurobiological similarity and perceived similarity in supporting different types of interaction success.

Let Them Be the Judge of That: Bias Cascade in Elite Dressage Judging

Sport performances judged subjectively often suffer from systematic errors due to biases, with the sport of equestrian dressage being no exception. This study examines whether international dressage judges display systematic errors while evaluating elite horse-rider combinations. Data from seven 5* Grand Prix dressage events between May 2022 and April 2023 were analyzed (510 judges' scores) using Multivariable Linear Regression Analysis. Five predictor variables-Home, Same Nationality, Compatriot, FEI Ranking and Starting Order-were studied in relation to Total Dressage Score (TS). The model accounted for 44.1% of TS variance; FEI Ranking, Starting Order, Compatriot, Same Nationality, and Home were statistically significant (p < 0.001). Judges exhibited nationalistic and patriotism-by-proxy biases, awarding significantly higher scores to riders from their countries (p < 0.001). FEI Ranking and Starting Order also influenced scores significantly (p < 0.001). These biases, combined, created a cascade effect benefiting a specific group of riders. To address this, measures should be taken to develop a more objective judging system that is based on unequivocal, transparent and evidence-based criteria and supports the continuous development of a fair, sustainable, equine welfare orientated sport that fosters societal acceptance.

Research-Problem Validity in Primary Research: Precision and Transparency in Characterizing Past Knowledge

Four validity types evaluate the approximate truth of inferences communicated by primary research. However, current validity frameworks ignore the truthfulness of empirical inferences that are central to research-problem statements. Problem statements contrast a review of past research with other knowledge that extends, contradicts, or calls into question specific features of past research. Authors communicate empirical inferences, or quantitative judgments, about the frequency (e.g., "few," "most") and variability (e.g., "on the one hand," "on the other hand") in their reviews of existing theories, measures, samples, or results. We code a random sample of primary research articles and show that 83% of quantitative judgments in our sample are vague and do not have a transparent origin, making it difficult to assess their validity. We review validity threats of current practices. We propose that documenting the literature search, reporting how the search was coded, and quantifying the search results facilitates more precise judgments and makes their origin transparent. This practice enables research questions that are more closely tied to the existing body of knowledge and allows for more informed evaluations of the contribution of primary research articles, their design choices, and how they advance knowledge. We discuss potential limitations of our proposed framework.

Physicians Disclosing Religion in Online Biographies: Patient Perceptions and Decision-Making in the United States

The inclusion of personal information about a healthcare provider is becoming more prevalent within online biographies as a means to help patients make more informed decisions about their future care. While many physicians indicate they are religious, and that spiritual well-being is an important part of one's overall health, what is unclear is what impact this sort of disclosure within an online biography might have on a prospective patient's perceptions of that provider. The current study took the form of a 2 (gender of provider: man; woman) × 2 (religion disclosure: yes; no) × 2 (activity: singing in choir; playing on softball team) between-subjects experiment. Participants (n = 551) in the USA were randomly assigned to view one of the eight biography conditions and then asked to rate their perceptions of the physician, and whether they would choose to make a future appointment with that physician. While there were no differences in perceptions (e.g., liking, trustworthiness), more participants who viewed a biography with a religion disclosure indicated an unwillingness to make a future appointment with that physician. A moderated mediation analysis revealed that this effect is only significant for participants with low levels of religiosity and is explained by these participants feeling less similar to an explicitly religious physician. Open-ended responses justifying their decisions found that religion disclosure played a much larger role in not choosing the physician (20% of responses) than for choosing the physician (3% of responses). However, participants wanting a physician of a different gender was the most cited reason for not wanting to select the provider (27.5% of responses). Recommendations for physicians contemplating adding an item about religion within their online biographies are discussed.

Russian Troll Vaccine Misinformation Dissemination on Twitter: The Role of Political Partisanship

Although vaccine misinformation has been a longstanding problem, the growth of social media and divides based on political ideology have raised novel concerns. One noteworthy example involves the Russian Internet Research Agency's deployment of operatives on Twitter (i.e., trolls) working to sow discord among the American public. We examine 1,959 tweets made by trolls between 2015 and 2017 about vaccination to better understand their efforts to spread vaccine misinformation. Our results indicate that misinformation was more likely to be perpetuated by left and right trolls than nonpartisan trolls. There was, however, relatively little user engagement with vaccine tweets containing misinformation and no differences in engagement with misinformation shared by partisan and nonpartisan trolls. Trends in the psycholinguistic properties of language in trolls' vaccine tweets suggest that right and left trolls were more likely to include cognitive process words (i.e., insight, causation, discrepancy, certainty, differentiation, and tentativeness) than were nonpartisan trolls.

Understanding Cyber-Racism Perpetration within the Broader Context of Cyberbullying Theory: A Theoretical Integration

The purpose of the current theoretical review is to argue for the theoretical integration of cyber-racism perpetration into the broader cyberbullying context-making note of the similarities between both types of nefarious online behavior that make this integration appropriate and the differences that make the integration less clear. Cyber-racism and cyberbullying victimization have been shown to be prevalent in youth and is related to poor psychological outcomes. Understanding both types of antisocial online behaviors have implications for the understanding and subsequent reduction of cyber-racism. Our review focuses on a cyber-racism model that proposes the importance of anonymity perceptions afforded to the online user to cause cyber-racism via several routes that focus on (a) online disinhibition, (b) deindividuation and group polarization, and (c) stereotypes. We discuss the tenets of this theory and the overlap with the Barlett Gentile Cyberbullying Model-a learning-based model that focuses on how anonymity eventually predicts cyberbullying via the development of positive cyberbullying attitudes. We believe that theoretical integration is necessary; however, future work needs to test several theoretical underpinnings of these models first. We end with a discussion of theoretical and intervention implications before discussing limitations and future work. Overall, we hope this review sparks interesting future research to understand cyber-racism and broaden the existing research on cyberbullying.

Group bias under uncertain environment: A perspective of third-party punishment

Third-party punishment (TPP) effectively promotes social cooperation and maintains social norms in which equity plays a decisive role. When third-party and players are affiliated with different groups, there are two distinct phenomena-in-group favoritism (IGF) and black sheep effect (BSE)-in a certain environment. Equity loses its function as a benchmark when the environment is uncertain (de Kwaadsteniet et al., 2013). Thus, we hypothesized that individuals have a stronger IGF because there is more room for interpretations of their behaviors when an uncertain environment results in ambiguous social norms. We utilized a common resource dilemma (CRD) to manipulate the environmental uncertainty by varying the range of the resource size: a certain environment is represented by a resource size of fixed tokens (i.e., 500 tokens) and an uncertain one is represented by that of 300 to 700 tokens. Additionally, group affiliation is manipulated by the alumni relation between the third-party and players. The present study revealed that the uncertain environment led to stricter costly punishment. The experiment confirms the IGF rather than the BSE. We found boundary conditions between IGF and out-group derogation (OGD). When the players' harvest was not obviously violated, the size of TPP for a control group without group affiliation manipulation anchored those of the in-group and OGD occurred. Opposite, when the harvest was obviously violated, the size of TPP for the control group anchored those of the out-group and IGF occurred. The gender of the third-party affects its decision to punish, with men anchoring the control group's punishment to the in-group and showing OGD, whereas women anchoring the control group's punishment to the out-group and showing IGF.

Outcome Evaluation in Social Comparison: When You Deviate from Others

Individuals often measure their performance through social comparison. With the increase in the deviation degree between the self and others, the outcome evaluation of individuals' abilities in the social comparison context is still unknown. In the current study, we used a two self-outcomes × three others' outcomes within-participant design to investigate the effect of the deviation degree of the self versus others in the social comparison context. Event-related potentials (ERPs) were measured while participants performed a three-person dot estimation task with two other people. When participants received positive results, the amplitudes of feedback-related negativity (FRN) and P300 showed a significant gradient change in the degree of deviation between the self and others (even win vs. better win vs. best win conditions). However, we did not find a similar progressive effect when participants received negative results (even loss vs. worse loss vs. worst loss conditions). These findings suggest that the deviation degree affects the primary and later processing stages of social comparison outcomes only when individuals received positive outcomes, which may reflect how people develop an empathic response to others. In contrast, people tended to avoid deeper social comparison that threatened their self-esteem when they received negative outcomes.

Should We Continue to Tell Autistic People that Their Brains are Different?

Autism is often considered to reflect categorically 'different brains'. Neuropsychological research on autism spectrum disorder (ASD) however, has struggled to define this difference, or derive clear-cut boundaries between autism and non-autism. Consequently, restructuring or disbanding the ASD diagnosis is becoming increasingly advocated within research. Nonetheless, autism now exists as a salient social construction, of which 'difference' is a key facet. Clinical and educational professionals must influence this cautiously, as changes to autism's social construction may counterproductively affect the quality of life of autistic people. This paper therefore reviews ASD's value as both neuropsychological and social constructs. Although lacking neuropsychological validity, the autism label may be beneficial for autistic self-identity, reduction of stigma, and administering support. Whilst a shift away from case-control ASD research is warranted, lay notions of 'different brains' may be preserved.

Strengthened social ties in disasters: Threat-awe encourages interdependent worldviews via powerlessness

Threat-awe, a negatively valenced variant of awe, is thought to strengthen social ties among community members. However, few empirical studies have examined the social functions of threat-awe. This study investigated whether threat-awe is linked to interdependent worldviews through feelings of powerlessness in comparison with positive awe. After remembering and describing their experiences of positive-or threat-awe, 486 Japanese participants reported on items regarding a small self, a sense of powerlessness, and interdependent worldviews. The results demonstrated that threat-awe encouraged interdependent worldviews via an increased sense of powerlessness, rather than the small self, compared to the positive awe condition. From textual perspectives, the semantic networks between awe-related and other words differed from the descriptions of threat-awe and positive awe experiences. These results provide a more nuanced understanding of the emotions of awe as well as new insights into human cooperation in the context of disasters.

The neurobiology of hatred: Tools of Dialogue© intervention for youth reared amidst intractable conflict impacts brain, behaviour, and peacebuilding attitudes

Myths, drama, and sacred texts have warned against the fragile nature of human love; the closer the affiliative bond, the quicker it can turn into hatred, suggesting similarities in the neurobiological underpinnings of love and hatred. Here, I offer a theoretical account on the neurobiology of hatred based on our model on the biology of human attachments and its three foundations; the oxytocin system, the "affiliative brain", comprising the neural network sustaining attachment, and biobehavioural synchrony, the process by which humans create a coupled biology through coordinated action. These systems mature in mammals in the context of the mother-infant bond and then transfer to support life within social groups. During this transition, they partition to support affiliation and solidarity to one's group and fear and hatred towards out-group based on minor variations in social behaviour. I present the Tools of Dialogue© intervention for outgroup members based on social synchrony. Applied to Israeli and Palestinian youth and implementing RCT, we measured social behaviour, attitudes, hormones, and social brain response before and after the 8-session intervention. Youth receiving the intervention increased reciprocity and reduced hostile behaviour towards outgroup, attenuated the neural marker of prejudice and increased neural empathic response, reduced cortisol and elevated oxytocin, and adapted attitudes of compromise. These neural changes predicted peacebuilding support 7 years later, when young adults can engage in civil responsibilities. Our intervention, the first to show long-term effects of inter-group intervention on brain and behaviour, demonstrates how social synchrony can tilt the neurobiology of hatred towards the pole of affiliation.

Not Next to You: Peer Rejection, Sociodemographic Characteristics and the Moderating Effects of Classroom Composition

While a range of sociodemographic characteristics are associated with a greater risk of peer rejection at school, it is currently unclear how key theoretical frameworks explaining rejection apply to such characteristics. This study examines how migration background, gender, household income, parental education and cognitive ability are linked to peer rejection. Building on person-group dissimilarity and social identity theory, the study assesses the moderating role of classroom composition and the extent to which students reject classmates who differ to themselves (i.e., outgroup derogation). Data is drawn from a nationally representative sample of 4215 Swedish eighth grade students (M_age = 14.7, SD_age = 0.39; 67% of Swedish origin; 51% girls) in 201 classes. While rejection based on migration background, gender, household income and cognitive ability was moderated by the school-class composition, only the rejection of immigrant background students, boys and girls was related to outgroup derogation. Furthermore, Swedish origin students' outgroup derogation increased as the share of immigrant background students decreased. Addressing social inequalities in rejection may require different strategies depending on sociodemographic characteristic.

Effect of Socioeconomic Status on Altruistic Behavior in Chinese Middle School Students: Mediating Role of Empathy

Previous studies have shown that socioeconomic status is correlated to altruistic behavior. The role of empathy as one of the motivations for altruistic behavior is gradually gaining attention among researchers. This study explores the role of empathy in the mechanisms of socioeconomic status and altruistic behavior in Chinese adolescents. A total of 253 middle school students from Northern China participated in this study, which included the dictator game and Interpersonal Relation Index. Results showed that (1) low-SES students behaved more generously than high-SES students; (2) the students were more generous to the low-SES recipients, as shown when offering them more money in the dictator game; (3) affective rather than cognitive empathy mediates the relationship between socioeconomic status and altruistic behavior. The findings provide evidence for the validation of the empathy-altruism hypothesis in a group of Chinese adolescents. Meanwhile, it reveals the path to improving altruistic behavior through the promotion of empathy, especially for individuals of high socioeconomic status.
