Why is muscularity sexy? Tests of the fitness indicator hypothesis

Evolutionary scientists propose that exaggerated secondary sexual characteristics are cues of genes that increase offspring viability or reproductive success. In six studies the hypothesis that muscularity is one such cue is tested. As predicted, women rate muscular men as sexier, more physically dominant and volatile, and less committed to their mates than nonmuscular men. Consistent with the inverted-U hypothesis of masculine traits, men with moderate muscularity are rated most attractive. Consistent with past research on fitness cues, across two measures, women indicate that their most recent short-term sex partners were more muscular than their other sex partners (ds = .36, .47). Across three studies, when controlling for other characteristics (e.g., body fat), muscular men rate their bodies as sexier to women (partial rs = .49-.62) and report more lifetime sex partners (partial rs = .20-.27), short-term partners (partial rs = .25-.28), and more affairs with mated women (partial r = .28).     

Being a Body: Women’s Appearance Related Self-Views and their Dehumanization of Sexually Objectified Female Targets

When sexually objectified, women are reduced to their bodies or sexual body parts and become likely targets of dehumanization. Not only men, but also women engage in this process. In the present research, we tested the link between women’s appearance related self-views and their tendency to dehumanize sexually objectified female targets. Specifically, we test two mediational models and predict that (1) women’s motivation to look attractive to men and (2) their tendency to internalize the sociocultural beauty standards are linked with the dehumanization of sexually objectified female targets, and their level of self-objectification mediates both relations. To test these hypotheses, a sample of 55 heterosexual undergraduate female students from Northern Italy volunteered. Participants’ motivation to look attractive to men, their level of internalization of the sociocultural beauty standards, and their tendency to self-objectify was measured. Results confirmed that only sexually objectified female targets were significantly dehumanized, while their non-objectified counterparts were not. Moreover, both participants’ motivation to look attractive to men and their tendency to internalize the sociocultural beauty standards were positively linked with the dehumanization of sexually objectified female targets. As expected, these relations were mediated by participants’ level of self-objectification. These results show that higher levels of self-objectification among those women who are motivated either to look attractive to men or to internalize the sociocultural beauty standards are linked with their tendency to dehumanize sexually objectified female targets.     

Human (Homo sapiens) facial attractiveness in relation to skin texture and color

The notion that surface texture may provide important information about the geometry of visible surfaces has attracted considerable attention for a long time. The present study shows that skin texture plays a significant role in the judgment of female facial beauty. Following research in clinical dermatology, the authors developed a computer program that implemented an algorithm based on co-occurrence matrices for the analysis of facial skin texture. Homogeneity and contrast features as well as color parameters were extracted out of stimulus faces. Attractiveness ratings of the images made by male participants relate positively to parameters of skin homogeneity. The authors propose that skin texture is a cue to fertility and health. In contrast to some previous studies, the authors found that dark skin, not light skin, was rated as most attractive.     

The Role of Body Weight,Waist-to-Hip Ratio,and Breast Size in Judgments of Female Attractiveness

It was demonstrated by Singh and Young (1995)that morphological features such as overall body fatdistribution measured by waist-to-hip ratio (WHR) andbreast size, influence judgments of femaleattractiveness, age, and desirability for relationships. Thepresent study was a replication and extension of thatresearch, using both male and female participants. Theresults supported the general findings of the original study, and as predicted, the effect of breastsize on attractiveness judgments depended on overallbody fat and WHR. The significance of interactionswithin the different morphological features whichdetermine female attractiveness were noted. Overall,there were surprisingly few sex differences. Results arediscussed in terms of the socio-biological theoriescurrently popular in the literature.     

Women’s physical attractiveness and short-term mating strategies

The current study examined the relationship between women’s physical attractiveness – as rated by themselves and a set of third-party raters – and their mating strategy and sexual experience. Male (N = 105) and female (N = 113) undergraduates rated the attractiveness of face and body photographs of 93 female undergraduates. Attractiveness ratings – particularly bodily attractiveness ratings – were significantly related to women’s mating psychology and behavior. More attractive women reported more sexual experience and a less restricted sociosexual orientation. In addition, some traits better predicted women’s perception of their overall attractiveness, and this pattern was further linked to mating strategy: more sociosexually unrestricted women showed a stronger relationship between bodily traits (i.e., body mass index) and overall attractiveness than less sociosexually unrestricted women. Discussion focuses on the findings that a woman’s mating strategy is linked to both her self-perceived and objective measures of attractiveness, particularly bodily attractiveness.     

A Critical Test of the Waist-to-Hip Ratio Hypothesis of Women's Physical Attractiveness in Britain and Greece

Body mass index (BMI) and body shape as measured by the waist-to-hip ratio (WHR) have been reported to be the major cues to women's bodily attractiveness. The relative importance of each of these cues was examined cross-culturally in two distinct countries, Greece and Britain. Fifty Britons, 25 British-Greeks, and 25 participants in Greece were asked to rate a set of images of real women with known BMI and WHR. The results showed that, regardless of the cultural setting, BMI is the primary determinant of women's physical attractiveness, whereas WHR emerged as a significant predictor for the Greek groups but not the British group. This finding is discussed in terms of the different gender roles occupied by Britons and Greeks. The discussion critically evaluates evolutionary psychological and sociocultural explanations of preferences for body weight.     

On models and vases: body dissatisfaction and proneness to social comparison effects

When and why do media-portrayed physically attractive women affect perceivers' self-evaluations? In 6 studies, the authors showed that whether such images affect self-evaluations depends jointly on target features and perceiver features. In Study 1, exposure to a physically attractive target, compared with exposure to an equally attractive model, lowered women's self-evaluations. Study 2 showed that body-dissatisfied women, to a greater extent than body-satisfied women, report that they compare their bodies with other women's bodies. In Study 3, body-dissatisfied women, but not body-satisfied women, were affected by both attractive models and nonmodels. Furthermore, in Study 4, it was body-dissatisfied women, rather than body-satisfied women, who evaluated themselves negatively after exposure to a thin (versus a fat) vase. The authors replicated this result in Study 5 by manipulating, instead of measuring, body dissatisfaction. Finally, Study 6 results suggested that body dissatisfaction increases proneness to social comparison effects because body dissatisfaction increases self-activation.     

More than just skin deep? Personality information influences men's ratings of the attractiveness of women's body sizes

This study examined the influence of personality information on perceptions of the physical attractiveness of a range of female body sizes. A sample of 2,157 male university students were randomly assigned to one of 10 groups in which they received personality information about women they were rating, or a control group in which they received no personality information. Controlling for participants' age and body mass index, results showed no significant between-group differences in the body size that participants found most attractive. However, participants provided with positive personality information perceived a wider range of body sizes as physically attractive compared with the control group, whereas participants provided with negative personality information perceived a narrower range of body sizes as attractive. Correlations showed that participants' own Extraversion was associated with their body size ratings. These results suggest that non-physical cues have an influence on the perception of physical beauty.     

OBJECTIFICATION THEORY

This article offers objectification theory as a framework for understanding the experiential consequences of being female in a culture that sexually objectifies the female body. Objectification theory posits that girls and women are typically acculturated to internalize an observer's perspective as a primary view of their physical selves. This perspective on self can lead to habitual body monitoring, which, in turn, can increase women's opportunities for shame and anxiety, reduce opportunities for peak motivational states, and diminish awareness of internal bodily states. Accumulations of such experiences may help account for an array of mental health risks that disproportionately affect women: unipolar depression, sexual dysfunction, and eating disorders. Objectification theory also illuminates why changes in these mental health risks appear to occur in step with life-course changes in the female body.     

Female physical attractiveness in Britain and Malaysia: a cross-cultural study

Two purported cues to perceived female physical attractiveness are body mass index (BMI) and body shape as measured by the waist-to-hip ratio (WHR). This study examined the relative contribution of both cues in several culturally socio-economically distinct populations. Six hundred and eighty-two participants from Britain and Malaysia were asked to rate a set of images of real women with known BMI and WHR. The results showed that BMI is the primary determinant of female physical attractiveness, whereas WHR failed to emerge as a significant predictor. The results also showed that there were significant differences in preferences for physical attractiveness along a gradient of socio-economic development, with urban participants preferring images of women with significantly lower BMIs than their rural counterparts. The findings are discussed in terms of evolutionary psychological explanations of mate selection, and sociocultural theory, which emphasises the learning of preferences for body sizes in social and cultural contexts.     

(Un)Changing Menopausal Bodies: How Women Think and Act in the Face of a Reproductive Transition and Gendered Beauty Ideals

Biomedical literature suggests that menopause primarily represents negative change in women’s lives. Feminist literature on menopause proposes that it can represent positive change or is a neutral experience for individual women. Conflicting characterizations result from different empirical emphases; biomedical research has focused on bodily change, and feminist research has highlighted social contexts for menopause. Results from interviews with a snowball sample of 61 women in 2001 illustrate how a change discourse on menopause and gendered beauty ideals combine to create a context within which some women believe that changes in their physical appearances can be attributed to menopause and that bodily change is problematic. In addition, during focus groups and in-depth interviews, women suggested that, in the face of these discourses or ideologies and changing external bodies, they face a “category crisis.’’ Interviewees also discussed how they attempt to prevent/mask bodily change in order to remain attractive, visibly feminine, and desirable in the eyes of men. Findings from this qualitative study illustrate that we must continue to explore women’s perceptions and experiences of bodily change during menopause, as we lack a full understanding of this developmental transition and its biosocial contexts.     

The (In)visible Body: Feminism,Phenomenology, and the Case of Cosmetic Surgery

This paper will examine the experience of and drive for bodily invisibility in women through the theoretical approaches of phenomenology and social constructionism. An examination of the social disruptions of bodily invisibility and the compulsive avoidance of such instances, particularly with respect to the fastidious maintenance of body comportment and appearance within the narrow parameters afforded by social norms, will lead to an exploration of the conflation of biomedicine with the beauty industry.     

Social Cognition and Evolutionary Psychology: Physical Attractiveness and Contrast Effects on Women's Self-perceived Body Image

Self-evaluations of body image were examined in a 2 (attractiveness of stimulus person) × 2 (sex of stimulus person) design to determine if contrast effects consistent with evolutionary psychology occur for women's self-perceptions of their body image. Main effects for attractiveness were hypothesized. Higher self-ratings for figure-related aspects of body image were predicted for women exposed to an unattractive male or female. These effects were significant. Women exposed to an unnattractive male or female had more positive feelings about figure-related aspects of their body image than women exposed to an attractive male or female. Contrast effects in accordance with evolutionary theory occur for aspects of body image that play a role in inferences regarding reproductive fitness.     

More Than Just Skin Deep? Personality Information Influences Men's Ratings of the Attractiveness of Women's Body Sizes

ABSTRACT

This study examined the influence of personality information on perceptions of the physical attractiveness of a range of female body sizes. A sample of 2,157 male university students were randomly assigned to one of 10 groups in which they received personality information about women they were rating, or a control group in which they received no personality information. Controlling for participants' age and body mass index, results showed no significant between-group differences in the body size that participants found most attractive. However, participants provided with positive personality information perceived a wider range of body sizes as physically attractive compared with the control group, whereas participants provided with negative personality information perceived a narrower range of body sizes as attractive. Correlations showed that participants' own Extraversion was associated with their body size ratings. These results suggest that non-physical cues have an influence on the perception of physical beauty.     

BMI,age, Mate Value,and Intrasexual Competition in Chilean Women

Attractiveness is the most important component of women intrasexual competition and it certainly has an impact in female’s perceived mate value (i.e., the value of an individual to the opposite sex as a potential mate). In the realm of intrasexual competition women are eager to emphasize their attractiveness and compete with rivals displaying these cues. Accordingly, age is an important feature of women’s appeal to the opposite sex; youth is highly valued by men, and is perceived by women as an important component of their attractiveness. Another trait that is a reliable cue of health and fertility is Body Mass Index (BMI). A large body of literature has associated BMI to female attractiveness. However, more information is necessary about the associations of BMI and age with mate value, and female intrasexual competition. In the present research we report two studies that examined the associations of BMI and age with estimates of self-perceived mate value and intrasexual competition in Chilean women (18–39 years). More specifically, we hypothesized inverse relationships of BMI and age with mate value (N?=?234), and intrasexual competition (N?=?308). We found partial support to our propositions. The results revealed inverse associations between BMI, mate value and mating success, but BMI with intrasexual competition were not related. In contrast, age had a strong and negative effect on intrasexual competition. We discuss our results within the framework of Evolutionary Psychology and consider the central role of attractiveness (estimated from BMI and age) in the mating strategies of women.     

Imagining Women’s Fertility before Technology

In the modern world, technology has enabled us to understand the connections between the menstrual cycle and female fertility and to observe the reproductive process even from conception. Unable to see inside the living body, however, eighteenth-century people imagined reproduction and fertility holistically. Their understanding of fertility was inseparable from the way in which they imagined the inner-workings of the humoral body. Although menstruation was understood to be connected to reproduction, it was considered unreliable, a peripheral indicator of fertility. Above all, the best marker of a woman’s fecundity was good overall health.     

APPEARANCE SELF-ATTITUDES OF AFRICAN AMERICAN AND EUROPEAN AMERICAN WOMEN: MEDIA COMPARISONS AND INTERNALIZATION OF BEAUTY IDEALS

African American (AA) women have reported less body image disturbance than European American (EA) women, but questions remain about the nature and extent of this difference. This study examined differences in the body image of 80 AA women and 89 EA women with an improved methodology that controlled for body size, distinguished between satisfaction with and importance of body features, and included nonweight (e.g., hair texture, skin color) as well as weight-related features. Results provide evidence that, in contrast to AA women, EA women (a) were more dissatisfied with both weight and specific appearance features, (b) compared themselves more often to media beauty figures and internalized Western beauty standards more, and (c) showed a significant relation between media comparisons and body dissatisfaction. Internalization of Western beauty ideals was related to body dissatisfaction in both groups of women.     

Female physical attractiveness in Britain and Japan: a cross‐cultural study

Two purported cues to female physical attractiveness are body mass index (BMI) and body shape as measured by the waist‐to‐hip ratio (WHR). This study examined the relative contribution of both cues in two culturally distinct populations. Eighty‐two male participants from Britain and Japan were asked to rate a set of images of real women with known BMI and WHR. Results showed that BMI is the primary determinant of female physical attractiveness, whereas WHR failed to emerge as a significant predictor. Results also showed that there were significant differences in preferences for physical attractiveness, with Japanese participants preferring images of women with significantly lower BMIs than Britons. Finally, results showed that the Japanese are more reliant on body shape than Britons when judging physical attractiveness. The findings are discussed in terms of evolutionary psychological explanations of mate selection, and sociocultural theories which emphasise the learning of preferences in social and cultural contexts.

Feminists Need to Look Beyond Evolutionary Psychology for Insights into Human Reproductive Strategies: A Commentary

The Sex Roles: Feminist Reappraisals of Evolutionary Psychology issue that addressed evolutionary psychology’s Sexual Strategies Theory is enlightening for feminists as well as those scholars who examine men and women’s behavior. As several articles in this issue show, there are mixed results in support of this theory. While some feminists may want to conclude that this an indication of the limited influence evolution and biology has on gendered behavior, the mixed results rather may be due to problems that are foundational to evolutionary psychology itself. For those interested in evolutionary perspectives of men and women’s behavior, they should look beyond evolutionary psychology and examine what evolutionary biology and behavioral ecology can provide to our understanding of reproductive strategies. This is evident in feminist and female evolutionists’ works that have created a new model of sexual dialectics, begun the retesting of A. J. Bateman’s foundational work that underlies parental investment theory and Sexual Strategies Theory, and provided new evidence of phenotypic and behavioral plasticity. This research has called into question past assumptions of male dominance and female passivity in mating, and continues to challenge evolutionary psychology’s claim that based on Sexual Strategies Theory, there are evolved psychological gender differences between men and women in their desire for short-term mating opportunities and sexual variety that are rooted in our evolutionary past and not very responsive to the current environments within which men and women are making these reproductive decisions.     

Male physical attractiveness in Britain and Greece: a cross-cultural study

The waist-to-chest ratio (WCR), body mass index (BMI), and waist-to-hip ratio (WHR) are the major cues to women's ratings of men's bodily attractiveness (J. T. Fan, W. Dai, F. Liu, & J. Wu, 2005; D. M. Maisey, E. L. E. Vale, P. L. Cornelissen, & M. J. Tovée, 1999; V. Swami & M. J. Tovée, 2005b). The authors examined the relative importance of each of these cues cross-culturally in Greece and Britain. Participants were 36 British and 40 Greek women who rated a set of images of real men with known WCR, BMI, and WHR. The results showed that, regardless of the cultural setting, WCR was the primary determinant of men's physical attractiveness to women, with BMI playing a minor role. However, there were also cross-cultural differences: The Greek women showed a stronger preference for a lower WCR and smaller overall body weight than did the British women. The authors considered possible explanations of these findings.
