Our understanding of such behavior may be illuminated by an evolutionary perspective that sees it as not just the product of social pressure, but as an exaggerated expression of behavior that may have once been adaptive. The reproductive suppression hypothesis suggests that natural selection shaped a mechanism for adjusting female reproduction to socioecological conditions by altering the amount of body fat. In modern Western culture, social and ecological cues, which would have signaled the need for temporary postponement of reproduction in ancestral environments, may now be experienced to an unprecedented intensity and duration. The Female-Female Competition Stress Test (FCST) is a measure of stress from adolescent female-female competition over status and over male attention. Based on the adaptive reproductive suppression model, this stress is likely to be associated with anorexic type behavior. This study replicates earlier work on this in a post-adolescent sample as well as extending the model to examine the relationship between female competition stress and disordered eating in an older adult (pre and post-menopausal) population. Results indicated that female competition stress scores predicted greater disordered attitudes toward eating as well as disordered eating behavior. While these effects decreased with age, they did not disappear and, in fact, female competition stress scores were elevated in postmenopausal women.</p>","PeriodicalId":7178,"journal":{"name":"Adaptive Human Behavior and Physiology","volume":"10 3-4","pages":"265 - 283"},"PeriodicalIF":1.2,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, those who perceive themselves to be more vulnerable to disease or are in poorer health should react more aversely to possible pathogenic agents because of the higher costs of infection. To test this hypothesis, we collected measures of current individual health (i.e., self-reported general health and self-perceived infectibility) and three domains of disgust in two studies: an in-person sample of United States university students and a global online sample of diverse ages. We also collected and assayed saliva samples for secretory immunoglobulin A (sIgA), provided by the university students. Results showed that lower sIgA and higher perceived infectibility independently predicted higher pathogen disgust. Poor self-reported general health was associated with higher pathogen disgust in the university sample, but not in the online sample. Finally, pathogen disgust mediated the effect of perceived infectibility on behavioral avoidance motivation. Overall, our findings support the functional flexibility of the behavioral immune system, such that those who are more vulnerable to disease are more likely to respond aversely to situations with high pathogen load; however, future research should consider other contextual factors which affect the strength of this relationship between individuals and populations.</p></div>","PeriodicalId":7178,"journal":{"name":"Adaptive Human Behavior and Physiology","volume":"10 2","pages":"211 - 231"},"PeriodicalIF":1.2,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141576656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most studies show that ELA blunts HPA responsivity while others show the opposite. To explain this inconsistency, researchers investigate factors that alter associations between ELA and HPA responsivity. One factor could be conditions that participants encounter before exposure to stressors. Life-history theory suggests ELA alters HPA function by signalling high mortality.

This commentary aims to re-evaluate Zagaria’s findings and conclusions. We raise two major concerns about his analysis. First, Zagaria’s EP syntax excluded key EP terms like fitness, psychological adaptation, and parental investment, while the SSSM syntax included homonyms (e.g., culture) not always relevant to SSSM (e.g., tissue culture in medicine). Second, the analysis included non-scientific journals from fields like gender studies, skewing results since EP is not intended to influence non-scientific fields like dance therapy or tourism studies. Focusing on high-impact psychology journals would better reflect EP’s influence. Methods: We revised the SSSM syntax to “cultural” and updated the EP syntax by adding “inclusive fitness,” “parental investment,” and “psychological adaptation.” Our analysis also used year-by-year data and 5- and 10-year rolling averages to assess trends more accurately. Results: Our analysis found that growth in EP and SSSM research is comparable over time, and the ratio of SSSM to EP papers was overstated by at least 23%. Conclusion: We highlight metrics that should be weighted more heavily than publication quantity, such as effect magnitude, universality, and replicability. By these metrics, EP is arguably outperforming the SSSM and embodies elements of the Kuhnian scientific revolution discussed by Zagaria (2024). This commentary offers a more optimistic vision for EP’s current status and future direction.</p></div>","PeriodicalId":7178,"journal":{"name":"Adaptive Human Behavior and Physiology","volume":"10 2","pages":"232 - 244"},"PeriodicalIF":1.2,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141195605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
