RESUMEN
Cooperation and competition are the most common forms of social interaction in various social relationships. Intergroup relationships have been posited to influence individuals' interpersonal interactions significantly. Using electroencephalography hyperscanning, this study aimed to establish whether intergroup relationships influence interpersonal cooperation and competition and the underlying neural mechanisms. According to the results, the in-group Coop-index is better than the out-group, whereas the out-group Comp-index is stronger than the in-group. The in-group functional connectivity between the frontal-central region and the right temporoparietal junction in the ß band was stronger in competition than cooperation. The out-group functional connectivity between the frontal-central region and the left temporoparietal junction in the α band was stronger in cooperation than competition. In both cooperation and competition, the in-group exhibited higher interbrain synchronization between the prefrontal cortex and parietal region in the θ band, as well as between the frontal-central region and frontal-central region in the α band, compared to the out-group. The intrabrain phase-locking value in both the α and ß bands can effectively predict performance in competition tasks. Interbrain phase-locking value in both the α and θ bands can be effectively predicted in a performance cooperation task. This study offers neuroscientific evidence for in-group favoritism and out-group bias at an interpersonal level.

Existing literature has extensively explored attitudes toward refugees; however, to the best of our knowledge, no study has specifically examined the relationship between the sense of global social responsibility and attitudes toward refugees. Therefore, this study investigated the mediating role of outgroup perspective-taking in the relationship of the sense of global social responsibility with negative stereotypes and intergroup anxiety. The data for this study were collected from a sample of 325 participants, with 53.5% males, aged between 18 and 47 years (Mage = 28.90 ± 7.08). The findings revealed that the sense of global social responsibility was positively related to outgroup perspective-taking and inversely related to negative stereotypes and intergroup anxiety. Also, perspective-taking exhibited negative relationships with negative stereotypes and intergroup anxiety. Mediation analyses showed that the sense of global social responsibility not only directly influenced the reduction of negative stereotypes and intergroup anxiety but also indirectly affected these attitudes through increased outgroup perspective-taking. These findings contribute to a deeper understanding of the underlying mechanisms that can effectively mitigate negative attitudes toward refugees. Findings also highlighted the potential of the sense of global social responsibility and outgroup perspective-taking in designing intervention programs aimed at reducing negative attitudes toward outgroup members, including refugees.
RESUMEN
While some species have affiliative and even cooperative interactions between individuals of different social groups, humans are alone in having durable, positive-sum, interdependent relationships across unrelated social groups. Our capacity to have harmonious relationships that cross group boundaries is an important aspect of our species' success, allowing for the exchange of ideas, materials, and ultimately enabling cumulative cultural evolution. Knowledge about the conditions required for peaceful intergroup relationships is critical for understanding the success of our species and building a more peaceful world. How do humans create harmonious relationships across group boundaries and when did this capacity emerge in the human lineage? Answering these questions involves considering the costs and benefits of intergroup cooperation and aggression, for oneself, one's group, and one's neighbor. Taking a game theoretical perspective provides new insights into the difficulties of removing the threat of war and reveals an ironic logic to peace-the factors that enable peace also facilitate the increased scale and destructiveness of conflict. In what follows, I explore the conditions required for peace, why they are so difficult to achieve, and when we expect peace to have emerged in the human lineage. I argue that intergroup cooperation was an important component of human relationships and a selective force in our species history in the past 300 thousand years. But the preconditions for peace only emerged in the past 100 thousand years and likely coexisted with intermittent intergroup violence which would have also been an important and selective force in our species' history.
RESUMEN
Decades of research have led to a solid understanding of the social systems of gregarious apes: chimpanzees, bonobos, gorillas, and gibbons. As field studies have increasingly collected data from multiple neighboring habituated groups, genetic and social interconnections have been revealed. These findings provide a more nuanced picture of intergroup relations in apes, and have led to claims in the literature that some ape taxa have multilevel societies. A multilevel society is defined as a nested collection of social entities comprising at least two discernible levels of social integration between the individual and the population. We argue that the evidence for multilevel sociality sensu stricto in apes is currently inconclusive and that it is premature to abandon the traditional classification of ape social systems. However, available findings appear to be consistent with the existence of some degree of higher social grouping patterns. We propose the term supra-group organization which may adequately capture ape social systems when viewed from a top-down perspective.

The natural resource management literature documents many reasons for pursuing collaborative processes, offering useful insights on how to manage conflict and facilitate productive deliberation in complex multistakeholder collaborative efforts. Moral foundations theory and self-affirmation theory can further help collaborative efforts mitigate conflicts caused by identity threats and the identity-protective reasoning these threats provoke. Moral foundations theory suggests an approach to increase collaboration by minimizing triggering language and helping people appreciate opposing viewpoints. Self-affirmation theory suggests a practical intervention that could be used to increase collaboration by desensitizing people to identity threats and reducing defensiveness. Taken together, these theories can contribute substantially to the understanding and practice of collaboration and conflict management for conservation.
Consideración de las Barreras Relacionadas con la Identidad que Enfrenta la Colaboración para la Conservación a través de la Teoría de Autoafirmación y la Teoría de Fundamentos Morales Resumen La literatura sobre el manejo de recursos naturales documenta muchas razones por las que es necesario buscar procesos colaborativos, los cuales ofrecen conocimiento útil sobre cómo manejar el conflicto. Estos procesos también facilitan la deliberación productiva dentro de los esfuerzos colaborativos complejos en los cuales participan múltiples actores. La teoría de fundamentos morales puede ayudar a que los esfuerzos colaborativos mitiguen los conflictos causados por las amenazas a la identidad y el razonamiento de protección de identidad que estas amenazas provocan. La teoría de fundamentos morales propone una estrategia para incrementar la colaboración al minimizar el lenguaje detonante y ayudar a que las personas aprecien los puntos de vista contrarios. La teoría de autoafirmación sugiere una intervención práctica que podría usarse para incrementar la colaboración al desensibilizar a las personas a tal grado que identifiquen amenazas y reduzcan la actitud defensiva. En conjunto, estas teorías pueden contribuir sustancialmente al entendimiento y la práctica de la colaboración y el manejo de conflictos para la conservación.

Community psychology is central to understanding how immigrants and more established residents of their new settings join together to develop a shared sense of community and membership. In our present study, we explored how newer (i.e., first- and second-generation immigrants) and more established community members form multiple positive psychological sense of community (PSOC) with one another. We conducted a multinational, qualitative study of PSOC through interviews with 201 first- and second-generation immigrants and third generation or more "receiving community members" in three contexts (Baltimore-Washington corridor of the U.S.; Torino, Italy; Lecce, Italy). Results indicated numerous similarities among the ways in which participants constructed PSOC in shared and nonshared communities, regardless of immigration/citizenship status, length of community residence, city, country, age, or gender. Small, proximal, and salient communities were often particularly important to building positive PSOC, which was formed around diverse membership boundaries. As intersectional beings, members converged and diverged on many characteristics, providing multiple opportunities for members to bring diversity to their communities while sharing other characteristics deemed essential to membership. Nonetheless, findings point to significant, structural challenges rooted in power and privilege that must be confronted to bridge the community-diversity dialectic and build strong, shared sense of community.

Behavioral mechanisms of intergroup feeding competition remain unclear, despite its importance as a benefit of group living. Japanese macaques in the coastal and highland forests of Yakushima, Japan, are ideal study subjects because the intensity of intergroup feeding competition differs without phylogenetic effects. We aimed to test whether macaques modify home range use and food patch use in response to the location-specific risk of intergroup encounters. Using behavioral data from 3 groups, we examined the border avoidance and the effects of food patch location on food patch use. All 3 groups used the border less frequently than expected from its area. In the coastal forest characterized by frequent intergroup aggression, the smaller subordinate group, not the larger dominant group, increased the number of co-feeding individuals along the border. This response might reduce the potential costs of intergroup aggression. Feeding duration in one patch, visual scanning, and co-feeding with adult males did not depend on food patch location for the 2 groups. In contrast, the highland group did not modify food patch use along the border owing to the low risk of intergroup encounters. Our results highlight the importance of intergroup hostility as a social factor affecting animal behavior.

RESUMEN
The studies presented here apply the concept of entitativity in order to understand how belonging to a particular geographical area - neighborhood - can determine the way others organize information and form impressions about area's residents. In order to achieve this objective, three studies were carried out. The first study aims to verify if a neighborhood varies in terms of perceived entitativity, and identify the physical and social characteristics of the neighborhoods that are more strongly associated with the perception of entitativity. The Study 2 and 3 used an experimental paradigm to explore how people's perceptions of neighborhoods' entitativity influenced their impressions of residents. To activate stereotypes, Study 2 used the name of real neighborhoods, and Study 3 employed only a set of pictures of unknown neighborhoods. The results show that the neighborhoods vary significantly with the regard to the perception of entitativity, and a set of physical attributes of place were strongly related with entitativity. The results showed that, independent of stimuli, the neighborhoods perceived as highly entitative, the supposed residents were subject to more extreme and quicker trait judgments, supported by greater confidence on the part of perceivers. Study 3 also reported that in highly entitative neighborhoods, the perceivers transferred more traits from the group to individual members. These results provide strong evidence that physical structure of neighborhoods imply different entitatity judgments that influences the way in which residents are perceived.
RESUMEN
PURPOSE: Intergroup contact is an effective strategy to improve intergroup relationships. Although intergroup relationships have been studied extensively, the individual roles of quantity and quality of contact in relationships with cognition, emotion, and intention of behavior toward other ethnic minority groups are not fully understood. This study explores the situation via network analysis among Zhuang and Yao ethnic minorities in Southwest China. METHODS: We investigated the quantity and quality of intergroup contact and cognition, emotion, and intention of behavior among a sample of 543 Zhuang and 490 Yao ethnic group members. Data were analyzed using the R-package. Network structures were analyzed via the Qgraph package, and the accuracy and stability of the network were measured via the Bootnet package; communities were detected via the Igraph package; bridge analyses were conducted via the Networktools package; and the network difference was compared via the Network Comparison Test package. RESULTS: The results indicated perceived intimacy is the central node. Quantity of contact constructed a community with "perceived connection," "sense of community," "knowledge about out-group," and "perceived similarity." Meanwhile, quality of contact constructed a community with "intergroup attitude" and a "feeling thermometer." The remainder of the nodes constructed two additional communities. The network global connectivity and structure between the two ethnic groups were highly similar. CONCLUSION: The study examined the quantity and quality of intergroup contact via network analysis for two ethnic minority groups. It was shown that the two groups' global network structures of intergroup contact and their effects are highly similar. Specifically, quantity and quality of contact produce different effects on intergroup relations. Quantity of contact has proximal effects, including instant cognitive and emotional response without depth cognition, while quality of contact has proximal effects that may change deep-seated cognition and subsequently improve intergroup relations.
