Numerous studies have explored the concept of social dominance and its implications for leadership within the behavioral and cognitive sciences in recent years. The current study aims to address the gap regarding the neural correlates of social dominance by investigating the associations between psychological measures of social dominance and neural features among a sample of leaders. Thirty healthy male volunteers engaged in a monetary gambling task while their resting-state and task-based electroencephalography data were recorded. The results revealed a positive association between social dominance and resting-state beta oscillations in central electrodes. Furthermore, a negative association was observed between social dominance and task-based reaction time as well as the amplitude of the feedback-related negativity component of the event-related potentials during the gain, but not the loss condition. These findings suggest that social dominance is associated with enhanced reward processing which has implications for social and interpersonal interactions.

The rapidly increasing number of elderly people in the world highlights the need for the development of innovative foods with modified textures that do not expose the elderly to the risks associated with food consumption (risk of aspiration, suffocation, and chocking). Providing specific food such as edible gel for the elderly population and the study of their properties is a challenge for the scientific community. There are some available gels in the supermarkets destined for the sports population, with specific texture and technological properties that could be used and extrapolated for senior people.

Scent marking through urine spraying is known to aid mate selection, territory marking and chemical communication in terrestrial, but not in aquatic mammals. We quantify an unusual aerial urination behaviour in botos (Inia geoffrensis) and discuss its potential functions. Between 2014 and 2018, we conducted land-based behavioural surveys on wild botos in central Brazil, recording the sequence, duration and social context of aerial urination.

Stereotypes are not only pervasive, they can also lead to discrimination against negatively-stereotyped groups. A gender-intelligence stereotype holds that men and boys are smarter than women and girls, despite no such evidence. Developmental research suggests that even children endorse this stereotype, and negative perceptions about self-worth in girls may be a consequence.

Most species of migrating birds use a combination of innate vector-based orientation programs and social information to facilitate accurate navigation during their life. A number of various interspecies hybridisations have been reported in birds. The traits of parents are expressed in hybrids in typical ways which are either intermediate, combined or heterotic.

Traditional gendered arrangements-norms, roles, prejudices, and hierarchies-shape every human life. Associated harms are primarily framed as women's issues due to more severe consequences women face. Yet, gendered arrangements also shape 's relationships, career paths, and health.
