Serotonergic Function

Background: Central serotonin is an essential neuromodulator for mental disorders. It appears a promising transdiagnostic marker of distinct psychiatric disorders and a common modulator of some of their key behavioral symptoms. We aimed to identify the behavioral markers of serotonergic function in rats and compare them to human deficits. Methods: We applied a comprehensive profiling approach in adult male Tph2-/- rats constitutively lacking central serotonin. Under classical and ethological testing conditions, we tested each individual's cognitive, social and non-social abilities and characterized the group organization (i.e. social network, hierarchy). Using unsupervised machine learning, we identified the functions most dependent on central serotonin. Results: In classical procedures, Tph2-/- rats presented an unexpected normal cognitive profile. Under the complex and experimenter-free conditions of their home-cage, the same Tph2-/- rats presented drastic changes in their daily life. Brain serotonin depletion induced compulsive aggression and sexual behavior, hyperactive and hypervigilant stereotyped behavior, reduced self-care and body weight, and exacerbated corticosterone levels. Group-housed Tph2-/- rats showed strong social disorganization with disrupted social networks and hierarchical structure, which may arise from communication deficits and cognitive blunting. Conclusions: Serotonin depletion induced a profile reminiscent of the symptomatology of impulse control and anxiety disorders. Serotonin was necessary for behavioral adaptation to dynamic social environments. In classical testing conditions, our animal model challenged the concept of an essential role of serotonin in decision-making, flexibility, and impulsivity, although developmental compensations may have occurred. These contrasting findings highlight the need to generalize the evaluation of animal models' multidimensional functions within the complexity of the social living environment.

The Impact

Abstract Living environments profoundly influence the aging process. This symposium presents research on two main aspects of the living environment and their relationships with cognitive health. The living environment is broadly defined, including both physical and social aspects. The physical environment is the characteristics of the built environment, such as tripping hazard in the home, cleanness of the community streets, and presence of deserted buildings, etc. The social environment is the cohesiveness with other people living in the neighborhood. Living environments have multiple layers; the physical environments encompass both in-home and in-community domains, whereas the social environment can be categorized as domestic versus community cohesiveness. This symposium includes studies with investigation scopes spanning from the micro to mezzo levels. The first presentation scrutinizes the buffering effect of marital relationships, as a form of domestic social environments, on cognition among older adults with vision and hearing impairments. Using the NHATS dataset, the second presentation examines social isolation as a potential mediator for the association between physical, social environments and global cognitive functioning. The third presentation evaluates the impact of living environments on cognition among Canadian older adults with multimorbidity. The last presentation examines how the physical environment affects sleep quality and thus influences older adults’ cognition. All four presentations are closely linked to the overarching theme of evaluating the environmental impact on cognition and provide possible explanations mediating the association observed. This symposium contributes to advancing gerontological knowledge by offering new perspectives on the social determinants of cognitive health.

Analogously to the works in the field of new social studies of childhood, this contribution deals with the concept of childhood as a social construction, in which children are considered as social actors in their own living environment, engaged in interpretive reproduction of the social. In this perspective the concept of agency is strongly stressed, and the vulnerability of children is not sufficiently taken into account. But in combining vulnerability and agency lies the possibility to consider the perspective of the subjects in the context of their social, political and cultural embeddedness. In this paper we show that what children say, what is important to them in general and for their well-being, is shaped by the care experiences within the family and by their social contexts. The argumentation for the intertwining of vulnerability and agency is exemplified by the expressions of an interviewed girl about her birth and by reference to philosophical concepts about birth and natality.

Abstract This work arose from the need to broaden the therapeutic approach and offer a differentiated health intervention proposal based on the understanding that the illness process has repercussions on all integrated systems of Being. Since 2019, the Health Center for the Elderly in Blumenau (SC-Brasil), specialized multi-professional service, offering support for biopsychoenergetic transformation with the practice of Yoga and Meditation, through a holistic and comprehensive view of health. It begins with the Multidimensional Assessment of the Elderly, with a guideline in welcoming and qualified listening, which considers the subject and all subjectivity. From there, the expanded diagnosis and the Singular Therapeutic Project are built and the consultations with the team and the 'Re-Conhecer group' begin. The activity is weekly, aimed at the elderly and their family, takes place in an appropriate place and lasts two hours. Welcoming, pranayama, mantras, kriyas and meditation are made, as well as reflections on free themes. The professionals who conduct the practice are the dentist, trained in yoga, and the social worker, the welcoming process continues individually after the activity. Due to subjectivity, results are routinely collected in a qualitative way from the participants' report. There is a perception on the part of the participants, therapists and members of the multidisciplinary team that this work provides improvement in cognitive abilities, self-care, well-being, self-confidence, creativity, improved sleep, autonomy, balance, strengthening bonds, joy, vitality. Key messages This initiative builds new models of health care, transcending the traditional biomedical model, according to the operational guideline for comprehensiveness, universal access and equity. Provokes reflections and builds a new perspective of life with quality and participation of the elderly as subjects of their health.

Background: The analysis has involved social interactions in a multicultural environment. The social context has been defined by the Vilnius region (Lithuania), where national, religious, and cultural differences exist across generations (multicultural community). The space of “social relationships”, as one of the modules of the WHO quality of life assessment, has been studied. An innovation of the research has been related to the analysis of the phenomenon of community of nationalities and cultures as a predictor of quality of life (QoL). The social motive of the research has been the historical continuity (for centuries) of the construction of the Vilnius cultural borderland. Here, the local community evolves from a group of many cultures to an intercultural community. Interpreting the data, therefore, requires a long perspective (a few generations) to understand the quality of relationships. We see social interactions and strategies for building them as a potential for social QoL in multicultural environments. Methods: The research has been conducted on a sample of 374 respondents, including Poles (172), Lithuanians (133), and Russians (69). A diagnostic poll has been used. The respondents were adolescents (15–16 years). The research answers the question: What variables form the interaction strategies of adolescents in a multicultural environment? The findings relate to interpreting the social interactions of adolescents within the boundaries of their living environment. The description of the social relations of adolescents provides an opportunity to implement the findings for further research on QoL. Results: An innovative outcome of the research is the analysis of 3 interaction strategies (attachment to national identification, intercultural dialogue, and multicultural community building) as a background for interpreting QoL in a multicultural environment. Their understanding is a useful knowledge for QoL researchers. The data analysis has taken into account cultural and generational (historical) sensitivities. Therefore, the team studying the data has consisted of researchers and residents of the Vilnius region. We used the interaction strategies of adolescents to describe the category of “social relationships” in nationally and culturally diverse settings.

Visuospatial Tasks

Evolutionary theory suggests that commonly found sex differences are largest in healthy populations and smaller in populations that have been exposed to stressors. We tested this idea in the context of men’s typical advantage (vs. women) in visuospatial abilities (e.g., mental rotation) and women’s typical advantage (vs. men) in social-cognitive (e.g., facial-expression decoding) abilities, as related to frequent binge drinking. Four hundred nineteen undergraduates classified as frequent or infrequent binge drinkers were assessed in these domains. Trial-level multilevel models were used to test a priori Sex × Group (binge drinking) interactions for visuospatial and social-cognitive tasks. Among infrequent binge drinkers, men’s typical advantage in visuospatial abilities and women’s typical advantage in social-cognitive abilities was confirmed. Among frequent binge drinkers, men’s advantage was reduced for one visuospatial task (Δ d = 0.29) and eliminated for another (Δ d = 0.75), and women’s advantage on the social-cognitive task was eliminated (Δ d = 0.12). Males who frequently engaged in extreme binges had exaggerated deficits on one of the visuospatial tasks, as did their female counterparts on the social-cognitive task. The results suggest sex-specific vulnerabilities associated with recent, frequent binge drinking, and support an evolutionary approach to the study of these vulnerabilities.

This paper is about the evolution of hominin intelligence. I agree with defenders of the social intelligence hypothesis in thinking that externalist models of hominin intelligence are not plausible: such models cannot explain the unique cognition and cooperation explosion in our lineage, for changes in the external environment (e.g. increasing environmental unpredictability) affect many lineages. Both the social intelligence hypothesis and the social intelligence–ecological complexity hybrid I outline here are niche construction models. Hominin evolution is hominin response to selective environments that earlier hominins have made. In contrast to social intelligence models, I argue that hominins have both created and responded to a unique foraging mode; a mode that is both social in itself and which has further effects on hominin social environments. In contrast to some social intelligence models, on this view, hominin encounters with their ecological environments continue to have profound selective effects. However, though the ecological environment selects, it does not select on its own. Accidents and their consequences, differential success and failure, result from the combination of the ecological environment an agent faces and the social features that enhance some opportunities and suppress others and that exacerbate some dangers and lessen others. Individuals do not face the ecological filters on their environment alone, but with others, and with the technology, information and misinformation that their social world provides.

The concepts of segregation and social distance have long been used to explain the social environment of stratified residential space. However, the social significance of occupation, though acknowledged, has rarely been applied spatially. In this study, we employed these three concepts to examine the social environment of the entire metropolitan employment space as defined by job location. Smallest space analysis was used to identify and compare the sociospatial segregation produced by workers' occupational distribution in employment and residential spheres. This empirical study focused on metropolitan Tel Aviv, Israel's largest urban area, using the latest available national census. Our findings show that the social milieu of employment differed from that of residence: blue-collar workers were segregated from white-collar workers; managers, clerks, and salespersons formed the core group; and gender and ethnic divisions characterised the sociospatial realm of employment. Overall, most employees changed their social environment when they went to work. The study indicates that spatial segregation, within each sphere and between the two spheres, is intrinsic to the capitalist – patriarchal order.

Selection For

The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. It has long been held that social interactions provide the selection pressures necessary for the evolution of advanced cognitive abilities (the ‘social intelligence hypothesis’), and in recent years decision-making in the context of cooperative social interactions has been conjectured to be of particular importance. Here we use an artificial neural network model to show that selection for efficient decision-making in cooperative dilemmas can give rise to selection pressures for greater cognitive abilities, and that intelligent strategies can themselves select for greater intelligence, leading to a Machiavellian arms race. Our results provide mechanistic support for the social intelligence hypothesis, highlight the potential importance of cooperative behaviour in the evolution of intelligence and may help us to explain the distribution of cooperation with intelligence across taxa.
