Judging romantic interest of others from thin slices is a cross-cultural ability
Skyler Place et al.
Evolution and Human Behavior, forthcoming
Abstract:
The ability to judge the romantic interest between others is an important aspect of mate choice for species living in social groups. Research has previously shown that humans can do this quickly - observers watching short clips of speed-dating videos can accurately predict the outcomes. Here we extend this work to show that observers from widely varying cultures can judge these same videos with roughly equal accuracy. Participants in the USA, China, and Germany perform similarly not only overall but also at the level of judging individual speed-daters: Some daters are easy to read by observers from all cultures, while others are consistently difficult. These cross-cultural performance similarities provide evidence for an adaptive mechanism useful for mate choice that could be resilient to cultural differences.

Ethnicity of Dating Partner, Pressure for Thinness, and Body Dissatisfaction
Alan Roberts, Michael Cunningham & Laura Dreher
Journal of Applied Social Psychology, forthcoming
Abstract:
Two studies explored the relation between ethnicity, attitudes toward body weight, dating behavior, and female body satisfaction. Study 1 found that White men expressed a lighter female ideal weight, more resentment about their girlfriend's weight, and more pressure for their partner's thinness than did Black men. Study 2 found that regardless of their own ethnicity, women who dated White men had lower body mass index (BMI), lower ideal weights, and reported experiencing lower levels of body acceptance by their dating partners. This lack of acceptance was associated with lower levels of body satisfaction. These results support the view that the differing aesthetic preferences of Black and White men contribute to differing levels of body satisfaction among Black and White women.

"We tested the sexualized-body-inversion hypothesis in the present study: If sexualized women are viewed as objects and sexualized men are viewed as persons, then sexualized female bodies will be recognized equally well when inverted as when upright (object-like recognition), whereas sexualized male bodies will be recognized better when upright than when inverted (person-like recognition)...Consistent with our hypothesis, our results showed that people recognized upright males (M = .85, SD = .17) better than inverted males (M = .73, SD = .17), t(77) = 6.29, p < .001, but this pattern did not emerge for females, t(77) = 1.38, p = .17...Additionally, participants recognized inverted females (M = .83, SD = .16) better than inverted males (M = .73, SD = .17), t(77) = 5.42, p < .001. This effect was not found for upright males and females, t(77) = 0.54, p = .59."

Abstract:
Previous research suggests that women may alter their behaviour during the fertile window of the menstrual cycle to attract a mate who has traits that indicate high-quality genes. We tested whether fertile women demonstrate greater behavioural engagement with a masculine compared to a less masculine male. The test was performed using a quiz show paradigm, in which a male host asked female participants general knowledge questions. The masculinity of the host was varied between participants. Women's performance on the quiz, as well as their romantic attraction to the host, was examined in relation to women's estimated cycle phase and host masculinity. Fertile compared to nonfertile women were more romantically attracted to the host and were faster to answer his questions, but only when he was portrayed as masculine. The results of the study are interpreted as being in keeping with Gangestad and Thornhill's cycle shift hypothesis (Menstrual cycle variation in women's preferences for the scent of symmetrical men. Proceedings of the Royal Society of London B: Biological Sciences, 1998;265:727-733).

Abstract:
Previous research suggests that heterosexual women's sexual arousal patterns are nonspecific; heterosexual women demonstrate genital arousal to both preferred and nonpreferred sexual stimuli. These patterns may, however, be related to the intense and impersonal nature of the audiovisual stimuli used. The current study investigated the gender specificity of heterosexual women's sexual arousal in response to less intense sexual stimuli, and also examined the role of relationship context on both women's and men's genital and subjective sexual responses. Assessments were made of 43 heterosexual women's and 9 heterosexual men's genital and subjective sexual arousal to audio narratives describing sexual or neutral encounters with female and male strangers, friends, or long-term relationship partners. Consistent with research employing audiovisual sexual stimuli, men demonstrated a category-specific pattern of genital and subjective arousal with respect to gender, while women showed a nonspecific pattern of genital arousal, yet reported a category-specific pattern of subjective arousal. Heterosexual women's nonspecific genital response to gender cues is not a function of stimulus intensity or relationship context. Relationship context did significantly affect women's genital sexual arousal - arousal to both female and male friends was significantly lower than to the stranger and long-term relationship contexts - but not men's. These results suggest that relationship context may be a more important factor in heterosexual women's physiological sexual response than gender cues.

Automatic attention towards face or body as a function of mating motivation
Hui Jing Lu & Lei Chang
Evolutionary Psychology, Winter 2012, Pages 120-135
Abstract:
Because women's faces and bodies carry different cues of reproductive value, men may attend to different perceptual cues as functions of their long-term versus short-term mating motivations. We tested this hypothesis in three experiments on 135 male and 132 female participants. When influenced by short-term rather than long-term mating motivations, men's attention was captured by (Study 1), was shifted to (Study 2), and was distracted by (Study 3) the waist/hip area rather than the face on photographs of attractive women. Similar effects were not found among the female participants in response to photographs of attractive men. These results support the evolutionary view that, similar to the attentional selectivity found in other domains of life, male perceptual attention has evolved to selectively capture and hold reproductive information about the opposite sex as a function of short-term versus long-term mating goals.

Cash in hand, want better looking mate: Significant resource cues raise men's mating standards
Jose Yong & Norman Li
Personality and Individual Differences, July 2012, Pages 55-58
Abstract:
Resources are a cardinal component of male mate value in the sexual exchange between men and women. Inspired by theories and research suggesting a link between mating and resource constructs as well as studies linking money and valuations of others, the current study tests the hypothesis that cues to resource availability may lead to higher mating standards for men, but not women. Participants were exposed to either stacks of paper, a small sum of money (104 Singapore dollars ∼USD$84), or a large sum of money (2600 Singapore dollars ∼USD$2100). Consistent with the hypothesis, after male - but not female - participants handled a large sum of money, they raised their minimum requirements for a date. We discuss how the results are consistent with an evolutionary perspective on mating and how future research can further investigate environmentally contingent self-assessments and strategies.

A Reexamination of Sex Differences in Sexuality: New Studies Reveal Old Truths
David Schmitt et al.
Current Directions in Psychological Science, April 2012, Pages 135-139
Abstract:
Recent evidence seems to call into question long-established findings of sex differences in sexuality, such as differences in mate preferences and desires for casual sex. In this article, we place new findings in a broader evidence-based context and show that they confirm previous perspectives on human mating. A wealth of evidence from real-world studies of actual mate choice and marital dynamics supports evolutionary mate-preference predictions. Converging evidence from patterns of extradyadic sex, mate poaching, sexual fantasies, pornography consumption, postcoital regret, sociosexual attitudes, and willingness to engage in casual sex supports the view that men and women have distinct short-term mating psychologies. This article highlights the fact that good science requires a constant re-evaluation of old truths and the proper placement of new studies in broad evidentiary contexts.

Introduction: Sexuality is a component of health and well-being for all women, including adolescents. Yet relationships between young women's health perceptions and sexual behavior are unclear.
Aim: We examined associations between perceived health and lifetime sexual experiences among young U.S. women.
Methods: We used data from 4,413 young women ages 15-24 years in the National Survey of Family Growth, 2002-2008. Descriptive, bivariate, and multivariate statistics estimated relationships between categories of perceived health and types of lifetime sexual experience.
Main Outcome Measures: A self-rated health Likert item and sexual history questions were administered with a computer-assisted survey instrument.
Results: Young women reported excellent (30%), very good (41%), good (23%), and fair-poor (6%) health. Sexual experiences included vaginal (64%), oral (64%), and anal (20%) sex. Negative experiences included involuntary sex (11%) and sexually transmitted infection (STI) history (8%). In multivariate logistic regression models, lower perceived health ("good" rather than "excellent") was positively associated with vaginal (odds ratio [OR] 1.5, confidence interval [CI] 1.1-2.1, P = 0.02), oral (OR 1.5, CI 1.1-2.1, P = 0.005), and anal (OR 1.4, CI 1.0-2.0, P = 0.03) sex. In models stratified by age, point estimates for vaginal (OR 1.8, CI 1.2-2.6, P = 0.002) and oral (OR 1.9, CI 1.4-2.6, P < 0.001) sex were higher among adolescents ages 15-19 years, but associations were insignificant among young adults ages 20-24 years. When controlling for negative sexual experiences, point estimates were stable in models including STI history but statistically insignificant when including involuntary sexual experience. Other characteristics associated with sexual experiences varied by type of experience and included age, race/ethnicity, employment situation, poverty level, insurance status, childhood family situation, religious service participation, cohabitation/marital experience, and body mass index.
Conclusions: Further investigation is warranted to disentangle potentially negative relationships between perceived health (as well as response bias and more objective health outcomes), sociodemographic factors, and diverse sexual experiences among young women in the United States.

Sexual Fantasies and Viewing Times Across the Menstrual Cycle: A Diary Study
Samantha Dawson, Kelly Suschinsky & Martin Lalumière
Archives of Sexual Behavior, February 2012, Pages 173-183
Abstract:
Recent research has revealed that many aspects of female sexuality change across the menstrual cycle. In this study, we examined changes in sexual fantasies and visual sexual interests across the menstrual cycle. A total of 27 single, heterosexual women (M age = 21.5 years) not using hormonal contraceptives answered questions on a web-based diary every day for 30 days about their sexual fantasies and behaviors. Twenty-two of them also completed a viewing time task during three different menstrual cycle phases (follicular, ovulation, and luteal) to assess changes in visual sexual interest. Ovulation status was determined by a self-administered urine test. Results showed that the frequency and arousability of sexual fantasies increased significantly at ovulation. The number of males in the fantasies increased during the most fertile period, with no such change for the number of females. Fantasy content became more female-like during ovulation, focusing more on emotions rather than explicit sexual content. Women displayed a category non-specific pattern of viewing time with regard to target age and gender, regardless of fertility status. Results were discussed in the context of the ovulatory shift hypothesis of female sexuality.

Women's visual attention to variation in men's dance quality
Bettina Weege, Benjamin Lange & Bernhard Fink
Personality and Individual Differences, forthcoming
Abstract:
Recent research shows that ‘good' male dancers display larger and more variable movements of their head, neck and trunk, and differ in certain personality characteristics from ‘bad' dancers. Here we elaborate on these findings by testing the hypothesis that ‘good' male dancers will also receive higher visual attention and will be judged as being more attractive by women. The eye-gaze of 46 women aged 19-33 years was tracked whilst they viewed pairs of video clips of male dancers in the form of avatars created using motion capture, each pair showing one ‘good' and one ‘bad' dancer together on the screen. In a subsequent rating task, women judged each dance avatar on perceived attractiveness and masculinity. Our data show that women viewed ‘good' dancers significantly longer and more often than ‘bad' dancers. In addition, visual attention was positively correlated with perceived attractiveness and masculinity, though the latter association failed to reach statistical significance. We conclude that (i) ‘good' male dancers receive higher visual attention from women as compared to ‘bad' dancers, and (ii) ‘good' dancers are being judged as more attractive. This suggests that in following mating-related motives, women are selectively processing male dynamic displays, such as dance movements.

Hair color and wages: Waitresses with blond hair have more fun
Nicolas Guéguen
Journal of Socio-Economics, forthcoming
Abstract:
The effect of employees' hair color on wages was experimentally tested in a tipping context. Waitresses in several restaurants were instructed to wear blond, red, brown or dark colored wigs. The effect of hair color on tipping according to patron's gender was measured. It was found that waitresses wearing blond wigs received more tips but only with male patrons. Waitresses' hair color had no effect on females' tipping behavior.

Archives of Sexual Behavior, February 2012, Pages 149-160
Abstract:
In a paradigm that asked participants to rate the sexual attractiveness of male and female swimsuit models, Lippa, Patterson, and Marelich (2010) showed that heterosexual men's category specificity exceeded heterosexual women's in two ways: (1) Heterosexual men showed much larger differences in their attraction and viewing times to male versus female photo models than heterosexual women, and (2) heterosexual men's attractions to female but not male models increased with model attractiveness whereas heterosexual women's attractions to both sexes increased with model attractiveness. The current study used the same paradigm to study category specificity in homosexual and heterosexual participants. In addition to replicating previous findings for heterosexual men and women, the results showed that homosexual men were high on category specificity, like heterosexual men, whereas lesbians showed lower levels of category specificity than men, but sometimes higher levels than heterosexual women.

Effectiveness of a National Media Campaign to Promote Parent-Child Communication About Sex
Kevin Davis, Douglas Evans & Kian Kamyab
Health Education & Behavior, forthcoming
Background: Although there is debate on the effectiveness of youth-focused abstinence education programs, research confirms that parents can influence their children's decisions about sexual behavior. To leverage parent-based approaches to adolescent sexual health, the U.S. Department of Health and Human Services launched the Parents Speak Up National Campaign (PSUNC) to encourage parent-child communication about sex. Previous experimental studies have found the campaign to be efficacious in increasing parent-child communication. But to date, the actual reach of the campaign and its real-world effectiveness in promoting parent-child communication has not been established. The present study addresses this gap.
Method: The authors surveyed 1,804 parents of 10- to14-year-old children from the nationally representative Knowledge Networks online panel. The survey included questions about parents' awareness of PSUNC ads and parent-child communication behaviors. The authors also analyzed market-level data on campaign gross rating points, a measure of market-level intensity of PSUNC advertising in the United States. Multivariate regressions were used to examine the association between PSUNC exposure and a three-item scale for parent-child communication.
Results: Overall, 59.4% of parents in the sample reported awareness of PSUNC. The authors found that higher market-level PSUNC gross rating points were associated with increased parent-child communication. Similar relationships were observed between self-reported awareness of PSUNC and increased frequency of communication and recommendations to wait. These associations were particularly strong among mothers.
Conclusions: This study provides the first field-based data on the real-world reach and effectiveness of PSUNC among parents. The data support earlier experimental trials of PSUNC, showing that the campaign is associated with greater parent-child communication, primarily among mothers. Further research may be needed to develop additional messages for fathers.

Contraceptive Paths of Adolescent Women Undergoing an Abortion in France
Caroline Moreau, James Trussell & Nathalie Bajos
Journal of Adolescent Health, April 2012, Pages 389-394
Purpose: Although more than 30,000 teenagers had an induced abortion in France in 2007 (14.3% of all abortions), little is known about their abortion experience. We explore young women's decisions related to their abortion and the patterns of abortion care among teenagers in France, and draw particular attention to the contraceptive circumstances surrounding the abortion.
Methods: The data are drawn from the French National Survey of Abortion Patients conducted in 2007, comprising 1,525 women aged 13-19 years.
Results: A majority of French teens (82%) reported their pregnancy was unplanned and took on the responsibility of having an abortion: 45% made the decision alone, 46% shared the decision with their family or partner, and 9% reported the decision was made on their family's or partner's request alone. Sixty-nine percent of teenagers were eligible for both medical and surgical abortions, but only 43% thought they were given a choice of methods. Two-thirds of pregnancies were caused by contraceptive misuse or failure, mostly due to condom slippage or breakage (26%) or inconsistent pill use (20%). In 68% of cases, teenagers were prescribed a more effective method than the one they were using before, although only 11% received a prescription for a long-acting method. One in five teenagers reported not receiving a prescription for contraception.
Conclusions: Our results reveal varying degrees of young women's autonomy in the decisions regarding their abortion. Although most teens switch to more effective methods of contraception after an abortion, only a minority receives a prescription for a long-acting method.

Evolution and Human Behavior, forthcoming
Abstract:
Sexual harassment and coercion have mainly been considered from a sex difference perspective. While traditional social science theories have explained harassment as male dominance of females, the evolutionary perspective has suggested that sex differences in the desire for sex are a better explanation. This study attempts to address individual differences associated with harassment from an evolutionary perspective. Considering previous research that has found links between sociosexual orientation inventory (SOI) and harassment, we consider whether this association can be replicated in a large, representative sample of high school students (N=1199) from a highly egalitarian culture. Expanding the previous studies which mainly focused on male perpetrators and female victims, we also examine females and males as both perpetrators and as victims. We believe that unrestricted sociosexuality motivates people to test whether others are interested in short-term sexual relations in ways that sometimes might be defined as harassment. Furthermore, unrestricted individuals signal their sociosexual orientation, and while they do not desire all individuals that react to these signals with sexual advances, they attract much more sexual advances than individuals with restricted sociosexual orientations, especially from other unrestricted members of the opposite sex. This more or less unconscious signaling thus makes them exploitable, i.e., harassable. We find that SOI is a predictor for sexual harassment and coercion among high school students. The paper concludes that, as expected, unrestricted sociosexuality predicts being both a perpetrator and a victim of both same-sex and opposite-sex harassment.

Abstract:
Viewing idealized body portrayals of men and women in advertising is known to have negative effects on men's self-esteem and body dissatisfaction, but little research investigates these effects across race/ethnicity. Racial minorities tend to idealize larger bodies than Whites and so might respond differently to advertising influences. We investigated whether exposure to idealized portrayals of male and female bodies in TV advertisements has different effects on men of different race/ethnicity. Additionally, we investigated whether implicit methods reveal different results than self-reports. One hundred and sixty Asian, Hispanic, and White American male undergraduates from a university in California (USA) were randomly assigned to watch TV advertisements portraying thin women, muscular men, or watched no ads. Their implicit self-esteem was measured using the Implicit Association Test, and a questionnaire assessed explicit self-esteem, actual-ideal body discrepancy, and perception of weight-related health-risks. Exposure to portrayals of muscular men decreased actual-ideal body discrepancy in all men. Exposure to portrayals of thin women increased men's implicit but not explicit self-esteem in Asian and Hispanic men only. Both these findings are consistent with a self-enhancing role of exposure to idealized male and female bodies in advertising, which is often referred to as a "fantasy effect". This study provides evidence that media exposure interacts with culturally local body ideals and so can produce varying effects in different racial/ethnic groups. This result could have important implications for interventions.

Journal of Adolescent Health, April 2012, Pages 410-413
Purpose: To investigate patterns and correlates of sexual and reproductive health (SRH) communication among adolescent women in the United States between 2002 and 2008.
Methods: We used data with regard to adolescent women (aged 15-19 years) from the National Survey of Family Growth (between 2002 and 2006-2008, n = 2,326). Multivariate analyses focused on sociodemographic characteristics and SRH communication from parental and formal sources.
Results: Seventy-five percent of adolescent women had received parental communication on abstinence (60%), contraception (56%), sexually transmitted infections (53%), and condoms (29%); 9% received abstinence-only communication. Formal communication (92%) included abstinence (87%) and contraceptive (71%) information; 66% received both, whereas 21% received abstinence-only. Between 2002 and 2006-2008, parental (not formal) communication increased (7%, p < .001), including the abstinence communication (4%, p = .03). Age, sexual experience, education, mother's education, and poverty were positively associated with SRH communication.
Conclusions: Between 2002 and 2008, receipt of parental SRH communication, especially abstinence, was increasingly common among United States adolescents. Strategies to promote comprehensive communication may improve adolescents' SRH outcomes.

Janelle Sobecki et al.
Journal of Sexual Medicine, forthcoming
Introduction: Sexuality is a key aspect of women's physical and psychological health. Research shows both patients and physicians face barriers to communication about sexuality. Given their expertise and training in addressing conditions of the female genital tract across the female life course, obstetrician/gynecologists (ob/gyns) are well positioned among all physicians to address sexuality issues with female patients. New practice guidelines for management of female sexual dysfunction and the importance of female sexual behavior and function to virtually all aspects of ob/gyn care, and to women's health more broadly, warrant up-to-date information regarding ob/gyns' sexual-history-taking routine.
Aims: To determine ob/gyns' practices of communication with patients about sexuality, and to examine the individual and practice-level correlates of such communication.
Method: A population-based sample of 1,154 practicing U.S. ob/gyns (53% male; mean age 48 years) was surveyed regarding their practices of communication with patients about sex.
Main Outcome Measures: Self-reported frequency measures of ob/gyns' communication practices with patients including whether or not ob/gyns discuss patients' sexual activities, sexual orientation, satisfaction with sexual life, pleasure with sexual activity, and sexual problems or dysfunction, as well as whether or not one ever expresses disapproval of or disagreement with patients' sexual practices. Multivariable analysis was used to correlate physicians' personal and practice characteristics with these communication practices.
Results: Survey response rate was 65.6%. Sixty-three percent of ob/gyns reported routinely assessing patients' sexual activities; 40% routinely asked about sexual problems. Fewer asked about sexual satisfaction (28.5%), sexual orientation/identity (27.7%), or pleasure with sexual activity (13.8%). A quarter of ob/gyns reported they had expressed disapproval of patients' sexual practices. Ob/gyns practicing predominately gynecology were significantly more likely than other ob/gyns to routinely ask about each of the five outcomes investigated.
Conclusion: The majority of U.S. ob/gyns report routinely asking patients about their sexual activities, but most other areas of patients' sexuality are not routinely discussed.

Knowledge of Medication Abortion Among Adolescent Medicine Providers
Mandy Coles, Kevin Makino & Rachael Phelps
Journal of Adolescent Health, April 2012, Pages 383-388
Purpose: Adolescents are at high risk for unintended pregnancy and abortion. The purpose of this study was to understand whether providers caring for adolescents have the knowledge to counsel accurately on medication abortion, a suitable option for many teenagers seeking to terminate a pregnancy.
Methods: Using an online questionnaire, a survey related to medication abortion was administered to U.S. providers in the Society for Adolescent Health and Medicine. We conducted χ2 analyses to evaluate the knowledge of medication abortion by reported adolescent medicine fellowship training, and to compare responses to specific knowledge questions by medication abortion counseling. Furthermore, we examined the relationship between providers' self-assessed and actual knowledge using ANOVA.
Results: We surveyed 797 providers, with a 54% response rate. Almost 25% of respondents incorrectly believed that medication abortion was not very safe, 40% misidentified that it was < 95% effective, and 32% did not select the correct maximum recommended gestational age (7-9 weeks). Providers had difficulty identifying that serious complications of medication abortion are rare. Those who counseled on medication abortion had more accurate information in all knowledge categories, except for expected outcomes. Medication abortion knowledge did not differ by adolescent medicine fellowship completion. Only 32% of respondents had very good knowledge, and self-assessed knowledge minimally predicted actual knowledge (r2 = .08).
Conclusions: Knowledge regarding medication abortion safety, effectiveness, expected outcomes, and complications is suboptimal even among adolescent medicine fellowship trained physicians, and self-assessment poorly predicts actual knowledge. To ensure pregnant teenagers receive accurate counseling on all options, adolescent medicine providers need better education on medication abortion.

Marlene Makenzius et al.
Scandinavian Journal of Public Health, March 2012, Pages 211-216
Background: Prevention of unintended pregnancies is a public health objective; however, the profiles of male partners of women who choose to abort are relatively unexplored.
Objective: To investigate risk factors among men who have repeated experience of being the partner of a woman electing an induced abortion.
Methods: A questionnaire was used to collect information from 590 men recruited through their pregnant partner who applied for an abortion in Sweden during 2009. A binary logistic regression model assessed risk factors associated with repeated experience of abortion.
Results: One-third of the men had previous experience of a pregnant partner electing an induced abortion. Univariate analysis indicated these men were older, had a lower educational level and less emotional support, and were more often tobacco users than men for whom it was the first experience of a partner choosing to abort. Independent risk factors were being a victim of physical, psychological, or sexual violence or abuse over the past year (OR 2.62, 95% CI 1.36-5.08), unemployment or sick leave (OR 2.58, 95% CI 1.57-4.25), and having children (OR 2.00, 95% CI 1.22-3.28). The men suggested improved sex and relationship education in school and lower unemployment rates could prevent unintended pregnancies and abortions.
Conclusions: Men with experience of repeat abortions present a picture of vulnerability that should be recognised in the prevention of unintended pregnancies. Increased work opportunities might be one important intervention to reduce the number of abortions.
