Life-history theory predicts that exposure to conditions typical of low socioeconomic status (SES) during childhood will calibrate development in ways promote survival harsh and unpredictable ecologies. Guided by this insight, the current research tested hypothesis SES predict eating absence energy need. Across three studies, we measured (Study 1) or manipulated (Studies 2 3) participants’ need gave them opportunity eat provided snacks. Participants also reported their SES. Results revealed...
Here, we propose a novel theoretical model linking present-focused decision-making to the activities of immune system. We tested our by examining relationship between inflammatory activity - in vivo and vitro characterized impulsivity, present focus, an inability delay gratification. Results support model, revealing that inflammation predicts these outcomes even after controlling for factors may contribute spurious linkage them. Moreover, subsequent analyses revealed was better fit data than...
Researchers in the evolutionary sciences have long understood men's desire to mate with a variety of women. Because obligatory investment offspring production is relatively small, men can directly increase their number descendants by mating multiple partners. Relatively less known, however, about conditions that favor sexual seeking Drawing on insights from biology and behavioral ecology, we examined relationship between perceived pathogen load an environment women's for variety. Across 5...
Although infectious disease has posed a significant and persistent threat to human survival welfare throughout history, only recently have the psychological behavioral implications of become topic research within sciences. This growing body work revealed suite affective cognitive processes that motivate avoidance disease-causing objects situations—a cascade loosely conceptualized as "behavioral immune system." Recent system linked surprisingly broad set phenomena. However, examining how is...
Here, we present a mechanistically grounded theory detailing novel function of the behavioral immune system (BIS), psychological that prompts pathogen avoidance behaviors. We propose BIS activity allows body to downregulate basal inflammation, preventing resultant oxidative damage DNA and promoting longevity. Study 1 investigated relationship between trait measure motivation in vitro vivo proinflammatory cytokine production. 2 examined this same predictor often associated with prolonged...
Abstract Early life stress increases one’s risk for health problems later in life, and many studies find that these effects are sex-differentiated. Here, we examined relationships between multiple sources of early adult immune function humans across several functional assays. Adult participants provided retrospective information about their childhood (a) socioeconomic status, (b) household unpredictability, (c) exposure to adverse experiences. Participants’ peripheral blood mononuclear cells...
It has long been hypothesized that attractiveness provides a cue to target's health and immunocompetence. However, much of the research testing this hypothesis relied on small number indirect proxies immune function, results have mixed. Here, we build past research, examining relationship between target (i) self-reported health, (ii) in vivo measures inflammation white blood cell count/composition, (iii) vitro tests targets' including (c 1 ) leucocyte proliferation response immunological...
Disgust is reasoned to operate in conjunction with the immune system help protect body from illness. However, less known about factors that impact degree which individuals invest pathogen avoidance (disgust) versus management (prophylactic immunological activity). Here, we examine role one's control over contact plays resolving such investment trade-offs, predicting (a) those low environments will pathogen-avoidance strategies and (b) each of these two occur a compensatory fashion (i.e. they...
Parenting is a universal element of human life. However, the motivational and attitudinal implications parenthood remain poorly understood. Given that many major religions prescribe parent-benefiting norms restricting sexual promiscuity socially disruptive behavior, we hypothesized both parental care motivation would predict higher levels religiosity.

Purpose The paper explores the implementation and process of a Participatory Action Research (PAR) project in Jacksonville, Florida. Using PAR principles, we sought to disrupt traditional dynamics research, co-generating knowledge with community. We aimed elevate disenfranchised voices foster effective solutions for neighborhood revitalization resilience, which are designed led by In this explore researcher positionality, examining how engagement community context profoundly influences...
People vary in climate change skepticism and their views on disaster cause prevention. For example, the United States boasts higher rates of than other countries, especially among Republicans. Research into individual differences that shape variation climate-related beliefs represents an important opportunity for those seeking ways to mitigate disasters (e.g., floods). In this registered report, we proposed a study examining how difference physical formidability, worldview, affect relate...
Biases in favor of culturally prevalent social ingroups are ubiquitous, but random assignment to arbitrary experimentally created groups is also sufficient create ingroup biases (i.e., the minimal group effect; MGE). The extent which bias arises from specific contexts versus more general psychological tendencies remains unclear. This registered report focuses on three questions. First, how MGE? Second, do critical cultural and individual factors moderate its strength? Third, does MGE...

Although allelic diversity at the major histocompatibility complex (MHC) has implications for adaptive immunity, mate choice, and social signalling, how MHC influences calibration of life history strategies remains largely uninvestigated. The current study investigated whether greater heterozygosity was associated with markers slower in a sample 789 North American undergraduates. Contrary to preregistered predictions previously published findings, not related any psychological...
