Abstract:
Why do researchers regularly observe a relationship between ecological conditions and the heaviness of female body weight ideals? The current research uses insights from life history theory and female reproductive physiology to examine whether variability in female body ideals might emerge from the different life history strategies typically adopted by individuals living in harsh versus benign ecologies. Across three experiments, we demonstrate that women who were sensitized to faster life history strategies during childhood – as indexed by earlier menarche or lower childhood SES – respond to cues of ecological harshness by shifting away from the thin body weight typically favored by Western women toward a heavier female body ideal. Additionally, although men’s perceptions of the ideal male body size did not shift in response to these cues, their perceptions of the ideal female body size did, with developmentally sensitized men also preferring a heavier female body size in the context of harsh ecologies.

Political Ideology and Racial Preferences in Online Dating
Ashton Anderson et al.
Stanford Working Paper, October 2013
Abstract:
What explains the relative persistence of same-race romantic relationships? One possible explanation is structural -- this phenomenon could reflect the fact that social interactions are already stratified along racial lines -- while another attributes these patterns to individual-level preferences. We present novel evidence from an online dating community involving more than 250,000 people in the United States about the frequency with which individuals both express a preference for same-race romantic partners and act to choose same-race partners. Prior work suggests that political ideology is an important correlate of conservative attitudes about race in the United States, and we find that conservatives, including both men and women and Blacks and Whites, are much more likely than liberals to state a preference for same-race partners. Further, conservatives are not simply more selective in general; they are specifically selective with regard to race. Do these stated preferences predict real behaviors? In general, we find that stated preferences are a strong predictor of a behavioral preference for same-race partners, and that this pattern persists across ideological groups. At the same time, both men and women of all political persuasions act as if they prefer same-race relationships even when they claim not to. As a result, the gap between conservatives and liberals in revealed same-race preferences, while still substantial, is not as pronounced as their stated attitudes would suggest. We conclude by discussing some implications of our findings for the broader issues of racial homogamy and segregation.

Abstract:
Previous research has shown that men with higher facial width-to-height ratios (fWHRs) have higher testosterone and are more aggressive, more powerful, and more financially successful. We tested whether they are also more attractive to women in the ecologically valid mating context of speed dating. Men’s fWHR was positively associated with their perceived dominance, likelihood of being chosen for a second date, and attractiveness to women for short-term, but not long-term, relationships. Perceived dominance (by itself and through physical attractiveness) mediated the relationship between fWHR and attractiveness to women for short-term relationships. Furthermore, men’s perceptions of their own dominance showed patterns of association with mating desirability similar to those of fWHR. These results support the idea that fWHR is a physical marker of dominance. This is the first study to show that male dominance and higher fWHRs are attractive to women for short-term relationships in a controlled and interactive situation that could actually lead to mating and dating.

Sexual Hookups and Adverse Health Outcomes: A Longitudinal Study of First-Year College Women
Robyn Fielder et al.
Journal of Sex Research, forthcoming
Abstract:
“Hookups” are sexual encounters between partners who are not in a romantic relationship and do not expect commitment. We examined the associations between sexual hookup behavior and depression, sexual victimization (SV), and sexually transmitted infections (STIs) among first-year college women. In this longitudinal study, 483 women completed 13 monthly surveys assessing oral and vaginal sex with hookup and romantic partners, depression, SV, and self-reported STIs. Participants also provided biological specimens that were tested for STIs. During the study, 50% of participants reported hookup sex and 62% reported romantic sex. Covariates included previous levels of the outcome, alcohol use, impulsivity, sensation seeking, and romantic sex. Autoregressive cross-lagged models showed that, controlling for covariates, hookup behavior during college was correlated with depression, Bs = .21, ps < .05, and SV, Bs = .19, ps < .05. In addition, precollege hookup behavior predicted SV early in college, B = .62, p < .05. Hookup sex, OR 1.32, p < .05, and romantic sex, OR 1.19, p < .05, were associated with STIs. Overall, sexual hookup behavior among college women was positively correlated with experiencing depression, SV, and STIs, but the nature of these associations remains unclear, and hooking up did not predict future depression.

Abstract:
The current study examined whether men’s ratings of women’s desirability as a long-term pairbond, based on static photographs, were related to the women’s second-to-fourth digit (2D:4D) ratio and their sexual attitudes and behavior. The 2D:4D ratio was measured in 164 women and facial photographs were taken of 55 of these women. All women completed the Sociosexual Orientation Inventory (SOI). Male participants (n = 89), masked to this information, rated the 55 female participants on their desirability as a long-term sexual partner, specifically along dimensions of faithfulness, youthfulness, and attractiveness. Ten independent judges rated women’s photographed faces on masculinity. Results indicated a significant negative relationship between women’s SOI scores and men’s faithfulness ratings (more unrestricted sociosexuality was associated with lower faithfulness ratings). There was also a significant positive relationship between right (but not left) 2D:4D ratio and faithfulness ratings (women with female-like ratios were rated as being more faithful). The SOI scores of the women were not related to 2D:4D ratios. These results suggest that the potential for sexual infidelity can be gleaned from static facial cues.

Fertile and Selectively Flirty: Women’s Behavior Toward Men Changes Across the Ovulatory Cycle
Stephanie Cantú et al.
Psychological Science, forthcoming
Abstract:
Past research shows that men respond to women differently depending on where women are in their ovulatory cycle. But what leads men to treat ovulating women differently? We propose that the ovulatory cycle alters women’s flirting behavior. We tested this hypothesis in an experiment in which women interacted with different types of men at different points in their cycle. Results revealed that women in the ovulatory phase reported more interest in men who had purported markers of genetic fitness as short-term mates, but not as long-term mates. Furthermore, behavioral ratings of the interactions indicated that women displayed more flirting behaviors when they were at high than at low fertility. Importantly, fertile women flirted more only when interacting with men who had genetic-fitness markers, not with other men. In summary, fertility not only alters women’s behavior but does so in a context-dependent way that follows adaptive logic.

Birds of a feather? Not when it comes to sexual permissiveness
Zhana Vrangalova, Rachel Bukberg & Gerulf Rieger
Journal of Social and Personal Relationships, February 2014, Pages 93-113
Abstract:
Prior research finds that sexually permissive individuals are judged more negatively than nonpermissive peers, placing them at risk of social isolation. Based on the positive assortment principle (i.e., preferences for similarity in attributes in close relationships), we examined whether participants’ own permissiveness mitigated negative judgments of permissive others in the same-sex friendship context. College students (N = 751) evaluated a hypothetical same-sex target with either 2 (nonpermissive) or 20 (permissive) past sex partners on 10 friendship-relevant outcomes. Participant permissiveness attenuated some negative evaluations. However, preferences were rarely reversed, and no moderation was found in five outcomes, suggesting the role of permissiveness-based positive assortment is limited, and evolutionary concerns may take precedence. Partial support for the sexual double standard was also found.

Hormonal and morphological predictors of women’s body attractiveness
Rachel Grillot et al.
Evolution and Human Behavior, forthcoming
Abstract:
Does women’s body attractiveness predict indices of reproductive capacity? Prior research has provided evidence that large breast size and low waist-to-hip ratio (WHR) are positively associated with women’s estrogen and progesterone concentrations, but no previous studies appear to have directly tested whether ratings of women's body attractiveness are predicted by higher concentrations of ovarian hormones measured across broad regions of the menstrual cycle. Here, we collected daily saliva samples across 1–2 menstrual cycles from a sample of young women; assayed the samples for estradiol, progesterone, and testosterone; obtained anthropometric measurements of the women’s bodies; and also obtained attractiveness ratings of the women’s bodies from photographs of them taken in standardized clothing with faces obscured. Contrary to previous research, mean hormone concentrations were uncorrelated with breast size and WHR. Body mass index (BMI) was a very strong negative predictor of body attractiveness ratings, similar to previous findings. Zero-order associations between women’s mean hormone concentrations and mean attractiveness ratings were not significant; however, after controlling for BMI, attractiveness ratings were independently and positively associated with both estradiol and testosterone concentrations. Discussion focuses on the implications of these findings for whether attractiveness assessment mechanisms are specialized for the detection of cues of differential fecundity in young women’s bodies.

Contrast Effects in Sequential Decisions: Evidence from Speed Dating
Saurabh Bhargava & Ray Fisman
Review of Economics and Statistics, forthcoming
Abstract:
We provide an empirical test of contrast effects— a bias where a decision-maker perceives information in contrast to what preceded it — in the quasi-experimental context of “speed dating” decisions. We document that prior partner attractiveness reduces the subsequent likelihood of an affirmative dating decision. This relationship is confined to recent interactions, consistent with a perceptual error, but not learning or the presence of a quota in affirmative responses. The contrast effect is driven almost entirely by male evaluators. Additional evidence documents the effect's linearity with respect to prior partner attractiveness, its amplification for partners of moderate attractiveness, and its partial attenuation with accumulated experience.

Sexual Risk Taking and Bullying Among Adolescents
Melissa Holt et al.
Pediatrics, December 2013, Pages e1481 -e1487
Background: Psychological and educational correlates of bullying have been explored extensively. However, little information is available about the link between bullying and sexual risk-taking behaviors among adolescents, though for some youth it may be that sexual risk taking emerges in response to bullying involvement. Associations for both heterosexual youth and those who identify as gay, lesbian, bisexual, transgender, or questioning (GLBTQ) should be considered, as should the influence of victimization exposures in other domains. Accordingly, associations among bullying, other victimization forms, and sexual risk-taking behaviors were examined among adolescents with particular consideration to sexual orientation.
Methods: A sample of 8687 high school students completed the Dane County Youth Survey, a countywide survey administered high school students from 24 schools. Participants were asked questions about their bullying involvement and sexual risk-taking behaviors (ie, engaging in casual sex and having sex while under the influence of alcohol or drugs).
Results: Results indicated that bullies and bully-victims were more likely to engage in casual sex and sex under the influence. In multivariate analyses, these findings held even after controlling for demographic characteristics and victimization exposures in other domains, but primarily for heterosexual youth.
Conclusions: Bullies and bully-victims engaged in more sexual risk-taking behaviors, although patterns of association varied by sexual orientation. Bullying prevention programs and programs aimed at reducing unhealthy sexual practices should consider a broader stress and coping perspective and address the possible link between the stress of bullying involvement and maladaptive coping responses.

The Framing Effect When Evaluating Prospective Mates: An Adaptationist Perspective
Gad Saad & Tripat Gill
Evolution and Human Behavior, forthcoming
Abstract:
Sex differences in the framing effect within the mating domain (and the underlying negativity bias) were investigated. In three separate studies, men and women evaluated eight prospective mates, each of which was described using either positively or negatively framed attribute information. The key difference between the three studies was the temporal context of the relationship for which the mates were considered (long-term versus short-term) and the quality of mates that were presented to the participants (high quality versus low quality). Overall, women exhibited larger framing effects than men (and in three of the four experimental conditions), and this sex difference was driven by women’s greater sensitivity to negatively framed information. This robust sex effect is a manifestation of the greater vigilance that women show within the mating domain (consistent with parental investment theory). At the attribute level, women displayed stronger framing effects than men in 10 of the 11 cases where significant results were found, and these were on attributes that accord with evolutionary principles (e.g., women exhibited larger framing effects for Earning Potential and Ambition while men yielded a larger effect in only one instance for Attractive Face). Finally, the sex differences in framing effects became stronger when evaluating short-term mates as compared to long term ones (in accord with the general guiding principles of Sexual Strategies Theory). The current paper situates the framing effect within an adaptationist framework and proposes, that in many instances, the pattern with which individuals succumb to it is an instantiation of ecological rationality.

Shame, Sexual Compulsivity, and Eroticizing Flirtatious Others: An Experimental Study
Raluca Petrican, Christopher Burris & Morris Moscovitch
Journal of Sex Research, forthcoming
Abstract:
Clinical observation and correlational studies with nonclinical samples suggest that a linkage between negative affective states (especially shame) and engagement in erotic pursuits typifies sexual compulsivity. The present study tested whether experimental induction of shame leads to increased interest in erotically suggestive targets among more sexually compulsive individuals. A total of 74 age-traditional heterosexual university students first recalled either an emotionally neutral or a shame-inducing personal experience, then completed a nonpredictive gaze-cueing task featuring flirtatious or emotionally neutral faces of the same or opposite sex. They also rated the faces’ attractiveness and completed a validated sexual compulsivity scale and two control measures (executive control, sociosexuality). Higher (versus lower) sexual compulsivity predicted weaker gaze-triggered attentional orienting in response to the flirtatious opposite-sex face in the shame (versus neutral) condition, and this was accounted for by (higher) attractiveness ratings of the flirtatious opposite-sex face. Shame thus appears to increase sexualization (i.e., reduces salience of agentic features and increases appeal of physical attributes) of erotically suggestive targets among more sexually compulsive individuals.
