The role of exogenous testosterone and social environment on the expression of sociosexuality and status-seeking behaviors in young Chilean men. Horm Behav 2024; 161:105522. [PMID: 38447330 DOI: 10.1016/j.yhbeh.2024.105522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 01/14/2024] [Accepted: 02/26/2024] [Indexed: 03/08/2024]
Abstract
Testosterone plays an important role as a social hormone. Current evidence suggests that testosterone is positively related to sociosexuality increasing the psychological attitudes toward investing in short-term versus long-term mating and promotes status-seeking behaviors both by dominance and prestige. In addition, the social environment may play an important role in the expression of mating effort through changes in sociosexuality and status-seeking behaviors. However, the causal relationships among the mentioned variables are still debated. We employed a double-blind, placebo-controlled within-individual design, in order to test and integrate the proposed causal relationships between testosterone and social environment over short-term and long-term mating orientation and dominant and prestigious status-seeking behaviors in a sample of 95 young Chilean men. We did not find evidence that the administration of exogenous testosterone increased short-term or decreased long-term mating orientation as expected. Moreover, exogenous testosterone did not affect either aggressive or cooperative behavior failing to support the social status hypothesis. We also did not find any relationship between short or long-term mating orientation with status-seeking behaviors. Finally, we found support for the effect of social environment on sociosexual attitudes but not over status-seeking behaviors. Thus, men reported higher levels of short-term mating orientation in the presence of a woman compared to a man and no differences were found for long-term mating orientation. We argue that sociosexuality may be expressed flexibly, but contextual factors such as the presence of women seem more important than changes in testosterone levels.

Abstract
In recent years, evolutionary life history theory has been used as a heuristic framework to understand mental health. This article reviews the life history theory and its integration with mental disorders and then introduces representative research methods and related empirical studies in the field of evolutionary psychopathology. In the end, this article concludes with future directions for further research examining and developing the evolutionary psychopathological framework.

Abstract
PURPOSE Violent victimization is concentrated in adolescence and is disruptive to both the timing and sequencing of key life course transitions that occur during this developmental stage. Drawing on recent work establishing the interpersonal consequences of youth victimization, we examined the effect of violent victimization on adolescents' timing of sexual debut and involvement in additional sexual risk behaviors (multiple sexual partnering and inconsistent contraceptive use). METHODS This study relied on secondary data analysis of 10,070 youth from four waves of the National Longitudinal Study of Adolescent to Adult Health (Add Health). To predict sexual debut and subsequent sexual risk-taking, analyses were limited to youth not yet sexually active at their wave I interview. RESULTS Findings from Cox proportional hazards models, negative binomial regression, and repeated measures ordinal logistic regression showed that adolescent victims of violence initiated sex sooner than non-victims and accumulated more sexual partners, but patterns varied by age at victimization. Youth victimized in late adolescence displayed an accelerated trajectory of sexual activity while youth victimized in early adolescence were less likely to debut or engage in other sexual risk behaviors (although younger victims were more likely to engage in other deviant activities). CONCLUSION Sexual activity is a normative part of adolescent development, yet this study finds that violent victimization may disrupt the timing of this life course task, exacerbating deviant risk-taking and undermining youths' subsequent well-being. This study also highlights the importance of life course criminology's attention to timing in lives, given that the consequences of victimization varied by the age when it occurred.

Abstract
It is emphasized that environmental predictability is another important condition that plays roles in slow strategies that are related to innovation; that economic inequality, except as measured by Gross Domestic Product (GDP) per capita, influences innovation; and that switching global life history from a slow to a fast strategy is a response adopted in response to new challenges during the post-Industrial Revolution period.

Abstract
Attachment styles, originated from early childhood experience, have been documented to influence human behaviors among adults. Drawing on life history theory, we examined whether or not, and how, attachment styles impact risk-taking behaviors beyond evolutionary valid domains, and explored the moderation role of parental status. In the consumer behavior context, three correlational studies provide convergent evidence that insecurely attached (vs. securely attached) consumers are more risk-taking in consumption situations like dining in a toilet-themed restaurant or buying genetically modified products. Specifically, insecurely attached consumers were more likely to take risks in two experiential purchase scenarios (Study 1) and this effect was not domain-specific (Study 2). In Study 3, we showed that safety perception mediated the relationship between attachment insecurity and risk-taking, which was manifested by purchase intentions toward genetically modified products. Specifically, insecurely attached individuals perceived genetically modified products to be safer and were more willing to make a purchase. Additionally, parental status moderates the relationship (Studies 2 and 3). We conclude with a discussion on the implications of attachment theory on consumer risk-taking behaviors from a life history perspective.

Abstract
More data are needed for a better understanding of the long-term influence of wider and combined stressful events in chimpanzee personality development. We evaluated the effects of bushmeat trade outcomes on the personality development in 84 African sanctuary chimpanzees. The chimpanzees presented different backgrounds regarding maternal care, social exposure, and abuse. We evaluated personality traits in chimpanzees using the Cattell 16PF personality questionnaire, the first application of this questionnaire in this species. We found that chimpanzees were rated as higher in anxiety after long social deprivation during infancy and juvenility, and if high human exposure was experienced. Mother-reared chimpanzees were rated as lower in restraint than hand-reared chimpanzees. Finally, mother-reared chimpanzees were rated as less dominant than hand-reared chimpanzees and rated higher when they had experienced severe mistreatment. Results suggest a wide range of possible stressful events could be potentially shaping rescued chimpanzees' personality and demonstrating the detrimental outcomes and consequences of the bushmeat and pet trade.

Abstract
This study used the life history (LH) theory to investigate how environmental cues are associated with Machiavellianism. A total of 252 undergraduate students completed self-report measures of social rank uncertainty, Machiavellianism, fast LH strategy, and dominance. The results indicated that Machiavellianism was related to a fast LH strategy. Furthermore, a fast LH strategy mediated an association between social rank uncertainty and Machiavellianism. Finally, Machiavellianism was positively associated with dominance. These findings may enhance our understanding of the evolutionary origin of Machiavellianism.
