Social tension or conflict between household cats is common but, because it often manifests as subtle behavioral changes, it can go unnoticed; it is precisely because most signs are subtle and unrecognized that the term \'tension\' is used. Where associated tension-related chronic fear-anxiety leads to more overt behavioral concerns and stress-associated disease, cats may face relinquishment by caregivers or even euthanasia if the tension is not relieved. The \'2024 AAFP intercat tension guidelines: recognition, prevention and management\' have been authored by a Task Force of board-certified veterinary and applied behaviorists and clinical experts in feline medicine and behavior convened by the American Association of Feline Practitioners. The aim is to support veterinary professionals in understanding social behavior between cats and, more specifically, in recognizing intercat tension, preventing or minimizing its occurrence and managing the stressors. In developing the Guidelines, the Task Force has modified the five pillars of a healthy feline environment to provide a framework to assist the prevention or management of intercat tension in households with two or more cats. Because feline social behavior is often misunderstood, the Guidelines debunk 10 common myths that have the potential to negatively impact the wellbeing of companion cats. Extensively illustrated with visual examples of intercat tension and an Appendix detailing a number of case studies, the Guidelines also include a comprehensive table of psychotherapeutic medications, and a detailed algorithm that outlines a systematic approach to preventing, recognizing and resolving intercat tension. A step-by-step approach to introducing a new cat into a household with one or more resident cats is included to further support veterinarians, and a range of management tools to promote client education accompany the Guidelines.

Primates exhibit diverse social systems that are intricately linked to their biology, behavior, and evolution, all of which influence the acquisition and maintenance of their gut microbiomes (GMs). However, most studies of wild primate populations focus on taxa with relatively large group sizes, and few consider pair-living species. To address this gap, we investigate how a primate\'s social system interacts with key environmental, social, and genetic variables to shape the GM in pair-living, red-bellied lemurs (Eulemur rubriventer). Previous research on this species suggests that social interactions within groups influence interindividual microbiome similarity; however, the impacts of other nonsocial variables and their relative contributions to gut microbial variation remain unclear. We sequenced the 16S ribosomal RNA hypervariable V4-V5 region to characterize the GM from 26 genotyped individuals across 11 social groups residing in Ranomafana National Park, Madagascar. We estimated the degree to which sex, social group identity, genetic relatedness, dietary diversity, and home range proximity were associated with variation in the gut microbial communities residing in red-bellied lemurs. All variables except sex played a significant role in predicting GM composition. Our model had high levels of variance inflation, inhibiting our ability to determine which variables were most predictive of gut microbial composition. This inflation is likely due to red-bellied lemurs\' pair-living, pair-bonded social system that leads to covariation among environmental, social, and genetic variables. Our findings highlight some of the factors that predict GM composition in a tightly bonded, pair-living species and identify variables that require further study. We propose that future primate microbiome studies should simultaneously consider environmental, social, and genetic factors to improve our understanding of the relationships among sociality, the microbiome, and primate ecology and evolution.

This study evaluated the ability of the Explicit Discrimination Scale (EDS) to produce comparable estimates among respondents according to gender, color/race, and socioeconomic status. Analysis was based on data from two studies with students from Brazilian public universities. An abridged version of the EDS with eight items was evaluated by the alignment method. Findings indicated violation of invariance between color/race and gender groups. Reports of discriminatory experiences had better comparability between socioeconomic status strata. This study showed that EDS should be used with caution, especially to compare discrimination estimates between respondents of different colors/races and genders. The observed violation of invariance reinforces the need for additional research examining whether such a scenario persists in larger and more diverse samples from Brazil.
O objetivo foi avaliar a capacidade da Escala de Discriminação Explícita (EDE) de produzir estimativas comparáveis entre grupos de gênero, cor/raça e posição socioeconômica. A análise se baseou em dados de dois estudos, realizados com estudantes de universidades públicas brasileiras. Uma versão abreviada da EDE com oito itens foi avaliada, utilizando o método alignment (alinhamento). Nossos achados indicaram violação de invariância entre grupos de cor/raça e gênero. Os relatos de experiências discriminatórias tiveram melhor comparabilidade entre estratos de posição socioeconômica. Este estudo demonstrou que a EDE deve ser utilizada com cautela, especialmente para fazer comparações de estimativas de discriminação entre respondentes de cor/raça e gênero distintos. A violação de invariância observada reforça a necessidade de pesquisas adicionais, examinando se tal cenário se mantém em amostras mais amplas e diversas do país.

The tendency for people to consider themselves morally good while behaving selfishly is known as moral hypocrisy. Influential work by Valdesolo and DeSteno (2007) found evidence for intergroup moral hypocrisy such that people were more forgiving of transgressions when they were committed by an in-group member than an out-group member. We conducted two experiments to examine moral hypocrisy and group membership in an online paradigm with Prolific workers from the United States: a direct replication of the original work with minimal groups (N = 610; nationally representative) and a conceptual replication with political groups (N = 606; 50% Democrats and 50% Republicans). Although the results did not replicate the original findings, we observed evidence of in-group favoritism in minimal groups and out-group derogation in political groups. The current research finds mixed evidence of intergroup moral hypocrisy and has implications for understanding the contextual dependencies of intergroup bias and partisanship.

People implicitly generalize the actions of known individuals in a social group to unknown members. However, actions have social goals and evaluative valences, and the extent to which actions with different valences (helpful and harmful) are implicitly generalized among group members remains unclear. We used computer animations to simulate social group actions, where helping and hindering actions were represented by aiding and obstructing another\'s climb up a hill. Study 1 found that helpful actions are implicitly expected to be shared among members of the same group but not among members of different groups, but no such effect was found for harmful actions. This suggests that helpful actions are more likely than harmful actions to be implicitly generalized to group members. This finding was replicated in Study 2 by increasing the group size from three to five. Study 3 found that the null effect for generalizing harmful actions among group members is not due to the difficulty of detecting action generalization, as both helpful and harmful actions are similarly generalized within particular individuals. Moreover, Study 4 demonstrated that weakening social group information resulted in the absence of implicit generalization for helpful actions, suggesting the specificity of group membership. Study 5 revealed that the generalization of helping actions occurred when actions were performed by multiple group members rather than being repeated by one group member, showing group-based inductive generalization. Overall, these findings support valence-dependent implicit action generalization among group members. This implies that people may possess different knowledge regarding valenced actions on category-based generalization.

Autoregressive language models, which use deep learning to produce human-like texts, have surged in prevalence. Despite advances in these models, concerns arise about their equity across diverse populations. While AI fairness is discussed widely, metrics to measure equity in dialogue systems are lacking. This paper presents a framework, rooted in deliberative democracy and science communication studies, to evaluate equity in human-AI communication. Using it, we conducted an algorithm auditing study to examine how GPT-3 responded to different populations who vary in sociodemographic backgrounds and viewpoints on crucial science and social issues: climate change and the Black Lives Matter (BLM) movement. We analyzed 20,000 dialogues with 3290 participants differing in gender, race, education, and opinions. We found a substantively worse user experience among the opinion minority groups (e.g., climate deniers, racists) and the education minority groups; however, these groups changed attitudes toward supporting BLM and climate change efforts much more compared to other social groups after the chat. GPT-3 used more negative expressions when responding to the education and opinion minority groups. We discuss the social-technological implications of our findings for a conversational AI system that centralizes diversity, equity, and inclusion.

When deciding what images we prefer, our brain must weigh many aesthetic variables, such as symmetry and complexity. To date, aesthetic research has mainly focused on investigating one variable at a time. In this article, we use symmetry and complexity to study the problem of multi aesthetic-variable interactions. For symmetry and complexity, there are two simple interaction hypotheses. The independence hypothesis proposes that the evaluation of aesthetic variables is mutually independent. Meanwhile, Birkhoff\'s aesthetic-measure hypothesis predicts that people prefer images high in symmetry and low in complexity, and dislike the opposite. To test these hypotheses, we generated images that systematically varied in levels of symmetry and complexity. We then compared the subjects\' preference maps to identify regions of likes and dislikes. Unlike the predictions from these hypotheses, we found that most, but not all subjects, formed two distinct natural clusters, termed \"islands,\" in terms of likes and dislikes. We also found that people with more art exposure were less likely to belong to an island. If someone did belong to an island, their gender influenced which cluster they belonged to. We discuss alternate hypotheses, possible mechanisms for the occurrence of islands, and their possible social implications.

Bevezetés: Az orvostanhallgatók marginalizált csoportokkal kapcsolatos ismeretei, előítéletei befolyásolhatják a betegekkel való kapcsolatukat. Célkitűzés: Az orvostanhallgatók véleményének vizsgálata abból a szempontból, hogy mely társadalmi csoportokat fogadnának el betegként kevésbé. Módszer: A Szegedi Tudományegyetem orvostanhallgatói önkéntes, anonim kérdőívet töltöttek ki 2021-ben (n = 410), mely több kérdéscsoportot tartalmazott (szociodemográfiai jellemzők, családi háttér, pályaválasztási motivációk, orvosi identitás alakulása, jövőbeli szakmai tervek, egyetem alatti munkavégzés, 19 társadalmi csoportra vonatkozóan kedvesség és kompetencia, társadalmi távolság mérése, saját tapasztalatok). Eredmények: A hallgatók a legkevésbé a bántalmazókkal, az oltásellenesekkel és a fogvatartottakkal szeretnének munkájuk során találkozni. Az orvostanhallgató-nők nagyobb arányban utasították el a bántalmazókat, míg férfi társaik inkább a hajléktalanokat, az alkoholistákat, az AIDS-betegeket, illetve a pszichiátriai betegségben szenvedőket, a felsőbb évesek pedig az oltásellenes és az AIDS-betegeket. A hallgatóknak a különböző társadalmi csoportokkal kapcsolatos tapasztalatai is nagyon eltérőek voltak. Személyesen a legtöbben romát, drogfogyasztót, pszichiátriai beteget, alkoholistát ismertek. A klinikai gyakorlatokon a leginkább romákkal, alkoholistákkal és pszichiátriai betegekkel találkoztak. Az oktatás során oltásellenesekről, alkoholistákról, romákról, hajléktalanokról, AIDS-betegekről hallottak a leggyakrabban. Megbeszélés: A hallgatók a különböző társadalmi csoportokba tartozó betegekkel kapcsolatban elfogadók voltak. Az előítéleteik mögött álló személyes, illetve az oktatás során szerzett tapasztalataik azonban nagyon szerteágazóak. Következtetés: Törekedni kell arra, hogy a hallgatók magatartás-tudományi, népegészségtani tanulmányaik alatt és klinikai munkájuk során is találkozzanak a különböző társadalmi csoportokkal, megismerhessék őket, így megtanulhassák a velük való megfelelő kommunikációt.
