Summary: This study suggests that, under unstable social structure conditions, low-status group members' support for group-based hierarchy and inequality (i.e., social dominance orientation; SDO) may serve as an ideological strategy to ensure the legitimacy of future ingroup status-enhancement. SDO is positively related to motivating group members to engage in actions favoring the ingroup by increasing their willingness to compete with a relevant higher-status outgroup.

Summary: This study aims to investigate the impact of psychosocial stress on hormonal responses during social interactions, specifically in terms of courtship opportunities. Heterosexual men and women were divided into control and stress groups, and engaged in social interactions with members of the opposite sex. The expected increase of testosterone levels in the control group was not observed, and there were no significant changes in testosterone levels in the stress group. However, analyses showed that relationship status played a significant role in cortisol and testosterone levels, with single individuals exhibiting higher cortisol levels and individuals in relationships experiencing a decrease in testosterone following the social interaction. These findings suggest that relationship status and psychosocial stress are important factors influencing the physiological responses to potential courtship opportunities.

Summary: This study reveals the importance of the social environment in determining the consequences of chemical contaminant exposure. Exposure affected dominant and subordinate fish differently, exhibiting a U-shaped dose-response curve, emphasizing the significance of nonlinear, low-dose effects.

Summary: This study investigated the relationships between sociality, hormone concentrations, and gut microbiome in domestic cats. It was found that individuals with high cortisol and testosterone concentrations had less contact with others, while those with high oxytocin concentrations exhibited less affiliative behaviors than expected. The frequency of contact among individuals was related to the similarity in gut microbiome, which was also associated with behavioral patterns and cortisol secretion. Interestingly, individuals with low cortisol and testosterone concentrations were more tolerant, making high-density living easier.

Summary: The boundaries of psychological phenomena have been pushed to new domains recently, including areas like social personality and ecosystem learning. The ascription of individual-based concepts to the social level is being analyzed, but the direct transposition of concepts from the individual to the social level can be problematic in some cases.

Summary: Hair can be used as a useful matrix to examine the hormonal status of animals. In this study, seasonal changes in cortisol and testosterone levels were evaluated in four feline species with different breeding strategies. Both hormones showed annual dynamic fluctuations, coinciding with the reproductive seasonality of the species. Sexual differences in testosterone levels were only found during the mating season, with higher levels in males. Cortisol levels increased during the mating period, and in caracal, increased cortisol was associated with animal transfer to smaller cages.

Summary: Living in a group can bring benefits to individuals, but also exposes them to intense competition. Individual behavior can directly and indirectly influence the behavior of others, as well as affect group characteristics. Dominant males in stable communities have higher testosterone levels compared to subordinate males.

Summary: Proper housing conditions are important for fish welfare. This study found that environmentally enriched housing conditions had minor effects on zebrafish behavior, but no significant influence on body length and stress hormone levels. It suggests that housing conditions should be considered in future research.

Summary: Using genetic variants associated with testosterone, Mendelian randomization analysis found little evidence that testosterone significantly affects socioeconomic position, health, or risk-taking behavior in men or women. This suggests that previously reported associations with socioeconomic position and health may be due to residual confounding or reverse causation.

Summary: The study found that an intensified training period in soccer led to neuromuscular fatigue, muscle damage, and changes in biochemical markers. Training load was correlated with recovery state and well-being among professional soccer players.

Summary: The study evaluated the supplementation effects of Acacia mearnsii tannin extract (TE) and encapsulated tannin extract (ETE) on the reproductive performance and oxidative status of South African Mutton Merino rams. It was found that encapsulation of TE provided the maximum benefit on sperm quality, and the seasonal effect had a significant impact on testicular measurements.

Summary: The study conducted a metabolomic analysis of serum samples from 253 subjects to classify them into Low, High or Normal endocrine classes based on hormone concentrations. An original processing algorithm was developed to distinguish these classes, and the minimal sample sizes were estimated for cortisol, IGF1, and testosterone to achieve a global prediction rate higher than 99.9% in larger size cohorts.

Summary: Through a study of 243 adolescents, it was found that basal testosterone and basal cortisol do not interact in decision-making and aggressive behavior, but under low CAR condition, the association of testosterone with cToM only occurred in female adolescents.

Summary: This study found that providing negative feedback resulted in temporary decreases in testosterone and increases in cortisol, but testosterone responses were attenuated when feedback providers were instructed to use cognitive reappraisal or affect utilization strategies.

Summary: This study demonstrates the use of social network analysis in improving learning outcomes by matching peers for peer learning and cultivating social cohesion in the classroom. The findings suggest that the distance between peers in the social network affects their tendency to use social information, and this effect is mediated by subjective closeness. Additionally, the results show that the use of social information is influenced by the peer's social status and perceived smartness.
