Temporal relation between pubertal development and peer victimization in a prospective sample of US adolescents
Peer victimization typically peaks in early adolescence, leading researchers to hypothesize that pubertal timing is a meaningful predictor of peer victimization. However, previous methodological approaches have limited our ability to parse out which puberty cues are associated with peer victimization because gonadal and adrenal puberty, two independent processes, have either been conflated or adrenal puberty timing has been ignored. In addition, …
Impact of the Covid‐19 pandemic on infant feeding practices in the United States
The coronavirus disease 2019 (COVID-19) pandemic increased food insecurity among US households, however, little is known about how infants, who rely primarily on human milk and/or infant formula, were impacted. We conducted an online survey with US caregivers of infants under 2 years of age (N = 319) to assess how the COVID-19 pandemic impacted breastfeeding, formula-feeding and household ability to obtain infant-feeding supplies and lactation su…
Evolved to Learn
Emotion adaptations have evolved in response to eons of selection pressures characteristic of social and physical life over the history of our lineage. Cues relevant to these distinct selection pressures should reliably elicit relevant emotions and motivate efficacious behavioral responses. Selection favors the strategic calibration of emotional processes to key contextual factors, such as fitness-relevant individual, situational, and/or cultural…
Perceived supernatural support heightens battle confidence
Religiosity has been historically linked with propensities for both antisocial aggression and prosocial bravery, and prior research employing indirect measures affirms that envisioning the support of supernatural agents promotes confidence in engaging in violent conflict. Here, we provide the first test of this hypothesis within a realistic combat paradigm (i.e., simulated knife fighting). We primed the presence of supernatural aid and collected …
Economic and Health Predictors of National Postpartum Depression Prevalence
The global prevalence of PPD is greater than previously thought and varies dramatically by nation. Disparities in wealth inequality and maternal-child-health factors explain much of the national variation in PPD prevalence
Self-reported spirituality correlates with endogenous oxytocin
Stranger danger
Unconscious vigilance
Individuals subtly reminded of death, coalitional challenges, or feelings of uncertainty display exaggerated preferences for affirmations and against criticisms of their cultural in-groups. Terror management, coalitional psychology, and uncertainty management theories postulate this "worldview defense" effect as the output of mechanisms evolved either to allay the fear of death, foster social support, or reduce anxiety by increasing adherence to …
