Human social hierarchies comprise two distinct bases of status: dominance and prestige. One can acquire high social status not only by physically intimidating others (dominance) but also by providing information goods to others (prestige). Given that prestige-oriented individuals need to be liked and accepted by others, we hypothesized that they would be more eager to reconcile with their coworkers when they were involved in interpersonal conflicts in their workplaces. Study 1 asked 487 respondents about their conciliatory behaviors in response to workplace conflicts. Prestige-oriented individuals were more apologetic (when they hurt someone in their workplace) and forgiving (when they were hurt by someone). However, analyses of a subsample of respondents who had conflicts with their followers showed that organizational leaders’ prestige orientation was associated only with forgiveness but not with apologetic behavior. Study 2 collected comparable data from 678 organizational leaders. Study 2 confirmed the results of the subsample analysis of Study 1. Compared with leaders low in prestige orientation, leaders high in prestige orientation were more likely to forgive their subordinates; however, they were no more likely to apologize to their subordinates.

Attachment styles are frequently viewed from within the evolutionary conceptual framework; however, their associations with evolutionary fitness are very rarely empirically explored. In the present research (N = 448), we analyzed the relations between romantic attachment (anxiety and avoidance) and various fitness indicators in Serbian adults: matting patterns (short and long-term mating), reproductive motivation, reproductive success (age of first birth, number of children, and grandchildren), and kin care (care for biological relatives in general and care for children). Congruent negative associations between insecure styles and fitness outcomes were found: this is particularly true for avoidance, which is negatively related to long-term mating, reproductive motivation, number of children, and kin care. Furthermore, the data showed that reproductive motivation and long-term mating may mediate the links between avoidance and the number of children. Anxiety was negatively related to reproductive motivation and the number of children; this attachment style was also negatively associated with care for children, but only in males. The present data suggest that secure romantic bonding may be evolutionary adaptive; the obtained results contradict some evolutionary theories that assume that insecure attachment has some adaptive benefits as well. Findings provide new insights into the role of romantic attachment in the behavioral ecology of pair bonding.

Intimate relationships are not always easy to keep. Accordingly, the current research has attempted to identify the strategies that people employ in order to improve their relationships with their partners. In particular, by using open-ended questionnaires in a sample of 219 Greek-speaking participants, we have identified 81 acts that people were likely to perform toward this end. Subsequently, using quantitative research methods in a sample of 511 Greek-speaking participants, we classified these acts into 14 broader relationship enhancement strategies. Trying to understand partners' needs, discussing problems with partners and showing more interest in a partner, were among the most likely to be used strategies. Moreover, we asked a sample of 367 Greek-speaking participants to rate how effective these strategies would be on them, and we found that, trying to understand partners' needs, discussing problems with partners, and showing one's love to a partner, were rated as the most effective strategies. Men and women, and people of different ages, were generally in agreement over what strategies they were willing to use, and how effective these strategies would be on improving their relationship with their partners.

In the course of human evolution, watching eyes have had an important influence on individual cooperative behavior. However, researchers have not explored how the valence of watching eyes affects cooperative behavior. Therefore, this study includes three studies to investigate the effect of watching eyes with different valences on cooperative behavior. The results showed that positive watching eyes (vs. negative watching eyes) induced positive emotions (PA) in the participants and thus increased their tendency to cooperate (Studies 1–2). The role of the decision maker (making decisions for oneself vs. making decisions on behalf of others) moderates the effect of watching eyes on cooperative behavior through emotion (Study 3). In conclusion, the valence of watching eyes significantly affects cooperation. This study not only further enriches research on environmental stimulation and cooperation but also provides inspiration and a reference for solving problems of cooperation in social dilemmas.

Research on men's sexual exploitation of women has documented that men's psychology tracks cues associated with the ease of women's exploitability. In the current studies, we examined a different class of cues hypothesized to aid men's use of sexually exploitative strategies: environmental cues to the likelihood of discovery. We defined likelihood of discovery as the perceived probability of identification when engaging in exploitative behavior (e.g., presence of others). We test the hypothesis that men's likelihood to rape increases when their perception of the likelihood of discovery is low in three studies. In Study 1, we conducted a content analysis of individuals’ responses (N = 1,881) when asked what one would do if they could stop time or be invisible. Besides the “other” category whereby there were no specific category for nominated behaviors, the most nominated category included sexually exploitative behavior—representing 15.3% of reported behaviors. Both Studies 2 (N = 672) and 3 (N = 614) were preregistered manipulations of likelihood of discovery surreptitiously testing men's rape likelihood to rape across varying levels of discovery. We found men, compared to women, reported a statistically higher likelihood to rape in both Studies 2 and 3: 48% compared to 39.7% and 19% compared to 6.8%, respectively. Across Studies 2 and 3, we found no statistical effect of the likelihood of discovery on participants’ likelihood to rape. We discuss how the presence of one's peers may provide social protection against the costs of using an exploitative sexual strategy if a perpetrator is caught.

Parental income is negatively and linearly related to the digit ratio (2D:4D; a proxy for prenatal sex steroids) of their children. Children of parents with high income are thought to be exposed to higher prenatal testosterone and develop lower 2D:4D. It is further hypothesized that 2D:4D relates to sexual orientation, although it is unclear whether the association is linear or curvilinear. Here, we consider patterns of parental income and its association with the sexual behavior of their adult children in a large online study (the BBC internet study). There were curvilinear relationships with parental income in male and female children. The highest frequencies of homosexuality and bisexuality were found in the lowest income group (bottom 25% of the population), the lowest frequencies in the income group representing the upper 50% of the population, and intermediate values in the other groups (low 50% and top 25% of the population). Parental income showed a U-shaped association with scores for same-sex attraction and an inverted U-shaped association with opposite-sex attraction. Thus, for the first time, we show that same-sex attraction is related to parental income. The curvilinear relationship between parental income and sexual behavior in their adult children may result from an association between very high fetal estrogen or testosterone and attraction to partners of the same sex. Among non-heterosexuals, and in both sexes, very high fetal estrogen may be associated with femme or submissive sexual roles, and very high fetal testosterone with butch and assertive sexual roles.
