Organizing efforts to date have primarily included cognitive scientists, computer scientists, and engineers, as well as physicians. At the same time anthropologists have started to explore the implications of neuroscience for understanding culture. Here we suggest that evolutionary neuroscience can be used to bridge knowledge obtained by social scientists with that obtained in the neurosciences for a more complete appreciation of the mind. We consider such a perspective as neuroanthropology. We use embodiment, an anthropological concept that has been substantiated by recent findings in neuroscience, to illustrate an integrative biocultural approach within neuroanthropology and suggest future possible directions for research.

This is significant as high-quality intimate relationships have been linked with greater well-being and better healthcare self-management in other disease contexts. For persons with epilepsy (PWEs), self-management is critical for seizure control, lower mortality, and better quality of life. In the current study, we conducted the first known investigation into the quality of PWEs’ intimate relationships and their self-management abilities. In a sample of 88 PWEs, using the Adult Epilepsy Self-Management Instrument, results demonstrate links between greater relationship satisfaction and sexual satisfaction with better self-management on seven of the eleven subscales: health communication, coping skills, social support, seizure tracking, seizure response, stress management, and wellness; satisfaction was unrelated to the treatment, safety, medical adherence, and proactivity subscales. Importantly, these results held while controlling for age, gender, social support, and presence of comorbidities. These findings provide some evidence of the importance of intimate relationships in understanding PWEs’ healthcare management abilities. Given that intimate relationship dynamics have been shown to be highly amenable to intervention, this is an area of potential interest for improving self-management in PWEs.

Body Image, 2022

This makes it critical to identify demographic and sociocultural correlates of sexuality-related body image: the subjective feelings, cognitions, and evaluations related to one's body in the context of sexual experience. We examined how sexuality-related body image differed by gender, sexual orientation, race, age, and BMI. Four items assessing sexuality-related body image were completed by 11,620 U.S. adults: self-perceived sex appeal of their body, nude appearance satisfaction, and the extent to which they believed that body image positively or negatively affected their sexual enjoyment and feelings of sexual acceptability as a partner. Men reported slightly less nude appearance dissatisfaction and fewer negative effects of body image on sexual enjoyment and sexual acceptability than women, but did not differ in reported sex appeal. Poorer sexuality-related body image was reported by people with higher BMIs, not in relationships, who had sex less frequently, among White compared to Black women and men, and among gay compared to heterosexual men. Data also revealed a subgroup of respondents who reported that their body image had a positive impact on their sex lives. The findings highlight a need for interventions addressing sexuality-related body image.

Evolutionary behavioral models suggest that when the sex ratio is high (more available men than women), violence against women is more likely to occur, whereas the Guttentag–Secord model suggests that when there is a surplus of men, violence against women is less likely to occur. Testing these theories, results show perception of a high sex ratio was significantly positively associated with experiences of IPV in the past 12 months and more tolerant attitudes toward IPV.

Moreover, much of the existing research on age-related patterns in human sexual behaviors and attitudes features samples of predominantly partnered individuals. Here, we test hypotheses concerning age- and sex-related differences in measures of sexuality among 1,522 single adults 21 years of age and older from throughout the United States. Consistent with expectations, we document age-related decreases in sexual behavior, ideal frequency of sexual behavior, perceived changes in sexual desire, and openness to an array of sexual behaviors (e.g., having sex with multiple partners), although sexual satisfaction increased with age in women but not men. Also consistent with expectations, men reported more frequent sexual behavior, ideal frequency of sexual behavior, greater perceived change in sexual motivation, and more openness to various sexual behaviors (e.g., a one-night stand) compared to women. Conversely, women reported higher sexual satisfaction and were more open to getting married than men. Interaction effects were also observed, including between age and sex on sexual satisfaction, with older women reporting relatively higher sexual satisfaction than older men. We place these findings in the wider body of research on human sexuality, contrasting this evolutionary life history approach with prevailing descriptive or biomedical foci on age-related sexual dysfunction.

In the current study, we investigated demographic correlates of engagement with emerging forms of sextech, defined here as internet-based applications, platforms, or devices used for sexual pleasure. Our web-based, demographically representative sample included 7,512 American adults aged 18-65 years, with a near-even gender split of men/women and moderate racial diversity (63% White). Participants indicated their engagement with eight forms of sextech, including six emerging forms of sexual technology (visiting erotic camming sites, participating in camming streams, teledildonic use, accessing virtual reality pornography, playing sexually explicit video games, and sexual messaging with chatbots or artificially intelligent entities) as well as two more common domains (online pornography and sexting). Participants who were younger, were men, had higher income, and were sexual minorities reported more frequent engagement with all forms of sextech assessed. Unlike prior work on pornography, religious individuals were more likely to engage with emerging sextech. Beyond online pornography (50%) and sexting (29%), visiting camming sites (18%) and playing sexually explicit video games (13%) were relatively common. Findings may contribute to the destigmatization of sextech engagement and forecast future norms in technologically-facilitated sexual behavior.
