    Applying minimally invasive biomarkers of chronic stress across complex ecological contexts
    (Wiley, 2022) DeCaro, Jason A.; Helfrecht, Courtney; University of Alabama Tuscaloosa
    Chronic stress is both theoretically and methodologically challenging to operationalize through biomarkers. Yet minimally invasive, field-friendly biomarkers of chronic stress are valuable in research linking biology and culture, seeking to understand differential patterns of human development across ecological contexts, and exploring the evolution of human sociality. For human biologists, a central question in measurement and interpretation of biomarkers is how stress-responsive physiological systems are regulated across diverse human ecologies. This article aims to describe a conditional toolkit for human biologists interested in the study of chronic stress, highlighting a mix of longstanding and novel biomarkers, with special focus on hair/fingernail cortisol, latent herpesvirus antibodies, allostatic load indices, and serial/ambulatory data collection approaches. Future trends in chronic stress biomarker research, including epigenetic approaches, are briefly considered. This overview considers: (1) challenges in separating a distinctly psychosocial dimension of chronic stress from adversity more broadly; (2) essential characteristics of human ecology that shape interpretation; (3) retrospective vs. longitudinal sampling; (4) the role of age, developmental effects, and local biologies; (5) different timescales of chronicity; and (6) the role of culture.

    Guys with Big Muscles Have Misplaced Priorities: Masculinities and Muscularities in Young South Korean Men's Body Image
    (Springer, 2023) Monocello, Lawrence; University of Alabama Tuscaloosa
    Men's body image is an issue of increasing importance as related illnesses continue to grow in prevalence around the world. However, cross-cultural attention to men's body image experiences has been relatively understudied. Based on data derived from cognitive anthropological methods of cultural domain analysis, I develop the concept of "muscularities" to more effectively examine the expectations inherent in multifarious models of body image men continuously navigate. Related to but distinct from "masculinities"-the recognition of culture-bound hierarchies of ways of doing-being a man-"muscularities" attends to the culturally particular ways in which muscles are conceived and evaluated as indices of socioeconomic status, intelligence, social skills, and professionalism, to name a few. Young South Korean men's experiences of chan'gunyuk ("small muscle") and manun kunyuk ("large muscle") challenge universalist assumptions about the kinds of muscles people value in global perspective, demonstrate the necessity of recognizing multiple muscularities in research, and encourage new directions of inquiry that attend to the consequences of variable embodiments of muscularities.

    Social genomics of healthy and disordered internet gaming
    (Wiley, 2018) Snodgrass, Jeffrey G.; Dengah, H. J. Francois; Lacy, Michael G.; Else, Robert J.; Polzer, Evan R.; Arevalo, Jesusa M. G.; Cole, Steven W.; Colorado State University; Utah State University; University of Alabama Tuscaloosa; University of California Los Angeles
    Objectives To combine social genomics with cultural approaches to expand understandings of the somatic health dynamics of online gaming, including in the controversial nosological construct of internet gaming disorder (IGD). MethodsResultsIn blood samples from 56 U.S. gamers, we examined expression of the conserved transcriptional response to adversity (CTRA), a leukocyte gene expression profile activated by chronic stress. We compared positively engaged and problem gamers, as identified by an ethnographically developed measure, the Positive and Negative Gaming Experiences Scale (PNGE-42), and also by a clinically derived IGD scale (IGDS-SF9). CTRA profiles showed a clear relationship with PNGE-42, with a substantial linkage to offline social support, but were not meaningfully associated with disordered play as measured by IGDS-SF9. ConclusionsOur study advances understanding of the psychobiology of play, demonstrating via novel transcriptomic methods the association of negatively experienced internet play with biological measures of chronic threat, uncertainty, and distress. Our findings are consistent with the view that problematic patterns of online gaming are a proxy for broader patterns of biopsychosocial stress and distress such as loneliness, rather than a psychiatric disorder sui generis, which might exist apart from gamers' other life problems. By confirming the biological correlates of certain patterns of internet gaming, culturally-sensitive genomics approaches such as this can inform both evolutionary theorizing regarding the nature of play, as well as current psychiatric debates about the appropriateness of modeling distressful gaming on substance addiction and problem gambling.
