After decades of research on the topic of reciprocity, there is still no consensus about the meaning of the term. Instead, there has been a proliferation of reciprocity terms with varied definitions, some of which overlap in ways that lead to confusion for scholars studying cooperation. In this paper, we provide a summary of 35 reciprocity terms an...

To better understand risk management and mutual aid among American ranchers, we interviewed and mailed a survey to ranchers in Hidalgo County, New Mexico, and Cochise County, Arizona, focusing on two questions: (1) When do ranchers expect repayment for the help they provide others? (2) What determines ranchers’ degrees of involvement in networks of...

For humans, sociality is inextricably linked to cooperation. The human life history, characterized by an extended altricial period during early childhood, required cooperation in the form of pair-bonding, alloparenting, intergenerational transfers of calories, and extensive cooperative food sharing among kin and non-kin. Cooperating to achieve mutu...

Microbes can influence host physiology and behavior in many ways. Here we review evidence suggesting that some microbes can contribute to host stress (and other microbes can contribute to increased resilience to stress). We explain how certain microbes, which we call “stress microbes,” can potentially benefit evolutionarily from inducing stress in...

Do crises bring people together or pull them apart? Here we examine how people’s willingness to help others and their perceived interdependence with others changed during the COVID-19 pandemic, and assess what factors are associated with any change. We collected data at 4 time points from the same cohort of 497 paid participants, starting on March...
Article
Friendships provide social support and mental health benefits, yet the COVID-19 pandemic has limited interactions with friends. In August 2020, we asked participants (N = 634) about their friendships during the pandemic as part of a larger study. We found that younger people and people with higher subjective SES reported more negative effects on th...

Given the importance of friendships during challenging times and the mixed associations reported between personality traits and disease-related behaviors, we investigated the influence of personality traits on friendships during the COVID-19 pandemic and how both influenced risky behaviors. In November 2020, we asked participants about their reacti...
Article
Background: Physical activity (PA) mitigated psychological distress during the initial weeks of the COVID-19 pandemic, yet not much is known about whether PA had effects on stress in subsequent months. We examined the relationship between change over time in COVID-related stress and self-reported change in PA between March and July 2020. Methods:...

Despite continued transmission of SARS-CoV-2 and sustained recommendations to wear protective face coverings, many people remained reluctant to comply throughout the early months of the pandemic. In the present study we surveyed an international cohort of participants on three different occasions from July to August, 2020 (N = 695) to examine the r...

What explains differences in attitudes towards wearing protective face masks to limit the spread of the SARS-CoV-2 virus? We investigated potential drivers of attitudes about mask wearing as part of a longitudinal study during the COVID-19 pandemic (N-participants = 711, N-countries = 36), focusing on people’s perceptions and feelings about seeing...

Since the beginning of the COVID-19 pandemic, wearing protective facial masks has become a divisive issue, yet little is known about what drives differences in mask wearing across individuals. We surveyed 711 people around the world, asking about mask wearing and several other variables. We found that people who reported greater perceived risk of i...

Individuals from small populations face challenges to initiating reproduction because stochastic demographic processes create local mate scarcity. In response, flexible dispersal patterns that facilitate the movement of individuals across groups have been argued to reduce mate search costs and inbreeding depression. Furthermore, factors that aggreg...

This paper investigates whether age profiles of ethnobiological knowledge development are consistent with predictions derived from life history theory about the timing of productivity and reproduction. We evaluate these predictions using an ethnobiological knowledge assessment tool developed for an off-grid pastoralist population, known as Choyeros...

Fitness interdependence refers to the degree to which two or more organisms influence each other’s success in replicating their genes. We designed a new scale of perceived fitness interdependence that explicitly measures how individuals’ feelings and outcomes covary with the outcomes of specific partners (e.g., “When [target] succeeds, I feel good....

We describe the first record and a 30 km southward range extension for Elgaria velazquezi (the Central Baja California Alligator Lizard) to a location in Sierra de la Giganta of Baja California Sur, Mexico. Local ranchers remarked that this was the first time they had ever noticed this species in the area. We describe two lizards of this species th...

This study examines the associations between objective and subjective measurements and impressions of body shape and cold pressor pain reporting in healthy adults. On the basis of sexual selection theory (SST), we hypothesized that body characteristics that are universally preferred by the opposite sex-specifically, lower waist-to-hip ratios (WHR)...

Background. Separate lines of research have shown that menstrual cycling and contextual factors such as the gender of research personnel influence experimental pain reporting. Objectives. This study examines how brief, procedural interactions with female and male experimenters can affect experimentally reported pain (cold pressor task, CPT) across...
