Appearance-Related Partner Preferences and Body Image in a German Sample of Homosexual and Heterosexual Women and Men

There is evidence that gender as well as sexual orientation can affect body image. In particular, heterosexual women and homosexual men seem to be more vulnerable to a negative body image compared to homosexual women and heterosexual men. One reason for this may be derived from the fact that heterosexual women and homosexual men try to attract male romantic partners: As men place more importance on physical attractiveness than do women, the pressure to fulfill the sociocultural beauty ideal is thus increased. The present online study investigated differences in appearance-related partner preferences and their associations with measures of body image and eating pathology in homosexual and heterosexual women and men. The non-representative sample consisted of 893 participants (n = 201 lesbian women, n = 192 gay men, n = 349 heterosexual women, and n = 151 heterosexual men), who completed silhouette measures assessing their perception and expectations regarding body fat and muscularity of their own body and the body of a potential romantic partner, as well as questionnaires on drive for thinness, drive for muscularity, and eating pathology. Overall, few differences in appearance-related partner preferences emerged between the four groups. However, compared to heterosexual women, homosexual men appeared to prefer higher muscularity in potential romantic partners, which was also associated with increased drive for thinness and muscularity and increased eating pathology. The present findings indicate that, irrespective of sexual orientation, women and men tend to share similar standards regarding their own and a potential partner’s physical appearance, potentially suggesting an increased hegemony of heteronormative beauty ideals in women and men in general.

Sex differences in the reward value of familiar mates in prairie voles

The rewarding properties of social interactions facilitate relationship formation and maintenance. Prairie voles are one of the few laboratory species that form selective relationships, manifested as "partner preferences" for familiar partners versus strangers. While both sexes exhibit strong partner preferences, this similarity in outward behavior likely results from sex-specific neurobiological mechanisms. We recently used operant conditioning to demonstrate that females work harder for access to a familiar versus unfamiliar conspecific of either sex, while males worked equally hard for access to any female, indicating a key sex difference in social motivation. As tests were performed with one social target at a time, males might have experienced a ceiling effect, and familiar females might be more relatively rewarding in a choice scenario. Here we performed a social choice operant task in which voles could repeatedly lever-press to gain temporary access to either the chamber containing their mate or one containing a novel opposite-sex vole. Females worked hardest to access their mate, while males pressed at similar rates for either female. Individual male behavior was heterogeneous, congruent with multiple mating strategies in the wild. Voles exhibited preferences for favorable over unfavorable environments in a non-social operant task, indicating that lack of social preference does not reflect lack of discrimination between chambers. Oxytocin receptor genotype at the intronic SNP NT213739 replicated a prior association with stranger-directed aggression within the test. These findings suggest that convergent preference behavior in male and female voles results from sex-divergent pathways, particularly in the realm of social motivation.

Timing, Initiators, and Causes of Divorce in a Mayangna/Miskito Community in Nicaragua

There exists a paucity of evolution-oriented research focusing on why relationships end, particularly in comparison to the substantial literature centered around individual preferences that define the beginning of relationships. In contrast, there is a long tradition in the fields of sociology and family studies of exploring divorce; however, this body of research is largely limited to studies of Western populations. We address these gaps in the literature with an examination of patterns of divorce among a small-scale horticultural population in Nicaragua. We test a number of hypotheses derived from behavioral ecology perspective regarding the timing and causes of divorce. Results lend support to all but one of the hypotheses. Overall divorce rates are comparable to U.S. rates; however, they tend to occur earlier in marriages. Children appear to provide a slight buffering effect against divorce, although age in marriage does not. Gender differences in the reported causes of divorce fall along the lines that would be expected due to differences in partner preferences reported in previous research. Finally, this population also exhibits a similar peculiar pattern exhibited by Western populations, in which divorce is more costly for women, and yet women are slightly more likely to initiate divorces than husbands.

Institutions or resources and capabilities? Explaining engagement in European sectoral social dialogue

In this article the authors analyse social partner engagement in European sectoral social dialogue, testing two prominent theories to disentangle sector and country dynamics: institutional and resources and capabilities theories. While institutional theory accounted for certain social partner preferences, resources and capability theory proved stronger in predicting participation and provided insight into regulatory preferences. The authors conclude that resources and capability theory better explains their case, associating it with weaknesses of transnational governance. Specifically, limited incentives for participation mean that social partners with fewer resources forego participation, entailing pre-eminence of social partners with greater resources and hindering outcomes reflecting national institutional influences.

A Chronic Lack of Perceived Low Personal Control Increases Women and Men’s Self-Reported Preference for High-Status Characteristics When Selecting Romantic Partners in Simulated Dating Situations

The question what people desire in their romantic partner has hitherto been dominated by a focus on gender. It has been repeatedly found that, when asked what they find important in selecting a partner, women indicate that they find status more important compared to men. Across five studies, we move beyond gender and base ourselves on general theories of control deprivation to test the effect of differences in perceived personal control on stated partner preferences. We find that low-control people—both women and men—value characteristics associated with status more in romantic partners at the expense of other desirable traits (Study 1a and 1b). Furthermore, in simulated dating settings, low-control people make corresponding dating choices and prefer hypothetical high-status partners over low- (Study 2a) or average-status partners (Study 2b). Our final study suggests a beneficial aspect: Thoughts of dating a high-status partner can repair low-control people’s feelings of control (Study 3).

Settling down without settling: Perceived changes in partner preferences in response to COVID-19

The goal of this study was to explore the positive association between concern related to COVID-19 and single individuals’ perceived changes to their partner preferences. In addition, we investigated the mediating role of fear of being single. Results indicated that people with greater COVID-19 concern perceived an increase in the importance of stability, family commitment, and physical/social attractiveness, as well as fear of being single. Fear of being single only negatively predicted the importance of physical/social attractiveness, whereas it positively predicted the importance of stability and family commitment. Thus, in most cases, people with a greater concern for COVID-19 perceived themselves to become more selective, even when they exhibit higher levels of fear of being single.

Partner Selection Across the Life-Course: Age Variation in Partner Preferences in the Czech Republic

The proportion of people seeking a partner later in life has increased in recent decades. However, studies exploring age variation in partner preferences are quite rare. We aim to fill this gap by examining the partner preferences for household care skills, financial resources, and education of unpartnered individuals aged 19–65 years ( n = 1145) who participated in speed-dating events in the Czech Republic. We hypothesized that the importance of these characteristics varies with age, and that this variance may differ for men and women. The results show that gender differences concerning these characteristics are mostly stable across age groups. The exception is the importance of household care skills, which increases for older men and decreases for older women. We found that older adults value financial resources more than younger adults, and that this increase is true for women and men. Finally, we did not find evidence that the importance of education differs with age.
