Modern-day environments differ drastically from those in which humans evolved, which likely has important implications for human mating psychology. Particularly notable is the modern advancement of hormonal contraceptives (HCs), which alter the natural hormones of the many women who use them. According to the HC congruency hypothesis, HCs alter sex...

Developing a better understanding of the individual differences associated with people's intentions to engage in unprotected sex is crucial to reducing rates of unplanned pregnancy and the spread of sexually transmitted diseases (STDs) among young adults. We thus used a sample of young adults in the U.S. to examine the extent to which two notable i...

Most people will get married, and maintaining a quality marriage is critical to well-being. Nevertheless, many intimates experience declines in marital satisfaction, and a substantial proportion of marriages dissolve. Drawing from functional perspectives of human mating, we argue that one source of marital discord and dissolution is that people var...

People differ in their tendencies to labor over decisions and to make choices that maximize their outcomes—a difference known as maximization. Here, we used two independent, 3-year longitudinal studies of newlywed couples to demonstrate that this individual difference in decision making has important implications for romantic relationships. Consist...

Male jealousy is an adaptive interpersonal process that functions to maintain relationships by reducing the likelihood of partner sexual infidelity. Ancestral men would have been most reproductively successful to the extent that they responded to signs of low partner commitment with increased jealousy and mate guarding. The current research showed...

There is still much to learn about attraction and relationship formation. Here, we introduce an innovative method that utilizes modern technology to permit large‐scale, observational study of dyadic behavior that may yield new empirical insights into how people choose partners and form relationships: virtual speed dating. In doing so, we provide a...

Attending to women's intrasexual competition generates a straightforward prediction: Insofar as women actors sometimes use distinct tactics of aggression (e. g., related to social exclusion), women targets might possess distinct interpretations of and reactions to those tactics. We test this using one such tactic common among women: disgust express...

Adaptive calibration models suggest that features of people’s childhood ecologies can shape their reproductive outcomes in adulthood. Given the importance of dyadic sexual desire (i.e., desire for sex with a partner) for relationships and reproduction, we examined the extent to which people’s childhood ecologies—especially the unpredictability of t...

One challenge many marital couples face is that they experience discrepant levels of sexual desire for one another. Such discrepancies are particularly likely to arise in mixed-sex relationships because, at least in long-term relationships, men tend to have higher levels of sexual desire for their partner than do women. But what underlies this sex...

The interface of sexual behavior and evolutionary psychology is a rapidly growing domain, rich in psychological theories and data as well as controversies and applications. With nearly eighty chapters by leading researchers from around the world, and combining theoretical and empirical perspectives, The Cambridge Handbook of Evolutionary Perspectiv...

Status is a universal feature of human sociality. A lesser-studied adaptive problem surrounding status is assessing who has which levels of status in a given group (e.g., identifying which people possess high status). Here, we integrate theory and methods from evolutionary social science, animal behavior, and social psychology, and we use an emotio...

Objectives: Suicidal ideation (SI) nearly always precedes lethal suicide attempts. Anger may play a role in SI, but this appears to vary by gender and nuances in this relationship are unclear. Method: We investigated whether levels of (a) anger and (b) SI vary by gender, (c) the cross-sectional relationship between anger and SI, and (d) if gende...

The behavioral immune system is an evolved adaptation comprised of automatic behavioral, cognitive, and affective reactions that has allowed humans throughout evolutionary history to avoid situations that risk infection by pathogens (e.g., physical proximity to sick people). Although behavioral immune system activation may be functional by helping...

By suppressing ovulation, hormonal contraceptives alter men's and women's mate choices that depend on women's menstrual cycles.

Infidelity can have harmful consequences for all those involved. Although prior research has demonstrated some reliable associations between certain personality traits and infidelity, the associations between other personality traits and infidelity are less clear. Moreover, prior research has been limited in addressing the role of partner personali...

Sex presumably facilitates pair bonding, but how do partners remain pair-bonded between sexual acts? Evolutionary perspectives suggest that sexual afterglow serves this purpose. We explored how long sexual satisfaction would remain elevated following sex and predicted that stronger sexual afterglow would characterize more satisfying partnerships. W...

The present study investigated the relations among physical attractiveness and inter- and intrasexual mate retention tactics used by individuals in romantic relationships. Seventy-three undergraduate romantic dyads were photographed and completed a questionnaire about their mate retention tactics. Independent judges rated the photographs for physic...

This article presents a response to the comment by B. J. Bushman, D. Romer, and P. E. Jamieson (2015). This reply addresses 2 issues raised by the commenters. First, they claim they and others have not made sensationalistic statements linking violent media to horrific acts of real-world violence. In response, we supply numerous examples of sensatio...

Violent media has often been blamed for severe violent acts. Following recent findings that violence in movies has increased substantially over the last few decades, this research examined whether such increases were related to trends in severe acts of violence. Annual rates of movie violence and gun violence in movies were compared to homicide and...

Laboratory and correlational studies often find a link between violent video games and minor or benign forms of aggressive behaviors (e.g., exposing an opponent to an unpleasant noise). Based on these studies, the media, lawmakers, and researchers often imply a link between violent video games and violent criminal behavior. Using a similar methodol...
