Evolutionary Psychology and Feminism

This article provides a historical context of evolutionary psychology and feminism, and evaluates the contributions to this special issue of Sex Roles within that context. We briefly outline the basic tenets of evolutionary psychology and articulate its meta-theory of the origins of gender similarities and differences. The article then evaluates the specific contributions: Sexual Strategies Theory and the desire for sexual variety; evolved standards of beauty; hypothesized adaptations to ovulation; the appeal of risk taking in human mating; understanding the causes of sexual victimization; and the role of studies of lesbian mate preferences in evaluating the framework of evolutionary psychology. Discussion focuses on the importance of social and cultural context, human behavioral flexibility, and the evidentiary status of specific evolutionary psychological hypotheses. We conclude by examining the potential role of evolutionary psychology in addressing social problems identified by feminist agendas.     

Feminism and Evolutionary Psychology: Allies, Adversaries, or Both? An Introduction to a Special Issue

This special issue on feminism and evolutionary psychology addresses current theory and research from feminist and evolutionary psychologists, focusing on gender differences in mate selection as conceptualized by Sexual Strategies Theory. This introduction begins with feminist critiques of evolutionary psychology as well as attempts by Darwinian feminists to integrate the two. It then reviews the papers, which generally fit into one of three lines of research. One group of papers critiques evolutionary psychology claims and presents research to support alternative theoretical explanations. A second group uses evolutionary psychology to support research on gender differences in alignment with Sexual Strategies Theory. A third group utilizes theory and empirical research to integrate evolutionary psychology and feminist theories. The introduction concludes with a call for furthering our understanding of the relationship between these theories.     

Gendered Political Behavior: A Darwinian Feminist Approach

Darwinian feminists use an evolutionary framework to examine behaviors that promote survival and reproductive success. Subsequent power relations between women and men arise from conflicting reproductive strategies and social scientists ought to reconfigure their understanding of the psychological and behavioral repertoires of women and men based on their dynamic interactions throughout human evolution. This paper is an addition to the feminist literature on women’s contribution to evolution through an exploration of autonomy and leadership in egalitarian society and uses a Darwinian feminist approach to understand gendered political behavior.     

Sexual Strategies Theory: Built for the Short Term or the Long Term?

The evolutionary paradigm has provided psychology with a different perspective on human behavior, and with beneficial results. Sexual Strategies Theory (SST; Buss and Schmitt 1993) has been the primary evolutionary theory for studying human sexual behavior. A review of some SST-related research suggests that some of the paradigm??s anticipated female-male differences are supported. However, closer examination of this research also reveals substantial female-male similarities in sexual behavior, inconsistent or unclear definitions of several important SST concepts, and the functional omission of several important topics from the SST research agenda. Further, male-female differences in sexuality may be driven by a subset of males. Directions for future research are suggested, including greater attention to individual and contextual factors.     

The desire for sexual variety as a key to understanding basic human mating strategies

Different authors have proposed competing evolutionary theories of human mating. Some argue that both sexes are designed to pursue a singular long‐term mating strategy. Others contend that both sexes are designed to function as essentially multiple maters. Sexual Strategies Theory (SST; D.M. Buss & D.P. Schmitt, 1993), in contrast, proposes that men and women have evolved short‐term and long‐term mating strategies that are pursued differently by each sex depending on theoretically derived dimensions of context. According to SST, the sexes tend to differ in the nature and prominence of the short‐term component of human mating–particularly the short‐term desire for sexual variety. The current research was designed to test competing empirical predictions from these contrasting theories by focusing on sex differences in the desire for sexual variety. Study 1 (N= 1,049), consisting of five separate samples, found large and consistent sex differences in the desire for short‐term sexual variety, even after employing statistical methods to control for skewed distributions and statistical outliers. Study 2 (N= 192) confirmed the results of Study 1 using an older, more mature sample. Study 3 (N= 50) again replicated these sex differences using an observer‐based method of inquiry. Study 4 (N= 167) found evidence that short‐term mating was unrelated generally to psychological dysfunction and may be related to mentally healthy personality characteristics in men. Discussion focuses on the viability of pluralistic compared with monomorphic evolutionary theories of human mating strategies.     

Sexual arousal and the pursuit of attractive mating opportunities

From an evolutionary perspective, sexual arousal may function, in part, to motivate the pursuit of attractive mating opportunities. We designed a study to test three aspects of this hypothesis. Several hundred heterosexual men and women completed a short survey about sexual arousal in response to a casual sex mating opportunity. We replicated previous research documenting that men report greater sexual arousal than women in response to a short-term mating opportunity. We argue that it is unlikely that a “downplaying of alternatives” psychology evolved, whereby mated individuals rate opposite-sex targets as less attractive than do unmated individuals, but instead that men and women have a relationship-seeking psychology, motivating them to pursue attractive mating opportunities. The results supported this relationship-seeking psychology rather than a downplaying alternatives psychology. Discussion addresses directions for future research on the motivational properties of sexual arousal.     

Goal-Driven Cognition and Functional Behavior: The Fundamental-Motives Framework

Fundamental motives have direct implications for evolutionary fitness and orchestrate attention, memory, and social inference in functionally specific ways. Motivational states linked to self-protection and mating offer illustrative examples. When self-protective motives are aroused, people show enhanced attention to, and memory for, angry male strangers; they also perceive out-group members as especially dangerous. In contrast, when mating motives are aroused, men show enhanced attention to and memory for attractive members of the opposite sex; mating motives also lead men (but not women) to perceive sexual arousal in attractive members of the opposite sex. There are further functionally specific consequences for social behavior. For example, self-protective motives increase conformity among both men and women, whereas mating motives lead men (but not women) to engage in anticonformist behavior. Other motivational systems trigger different adaptive patterns of cognitive and behavioral responses. This body of research illustrates the highly specific consequences of fitness-relevant motivational states for cognition and behavior, and highlights the value of studying human motivation and cognition within an evolutionary framework.     

How do Iranian women from Rafsanjan conceptualize their sexual behaviors?

In Iran, women’s sexual behaviors have not been studied in detail. The aim of this study was to explore the sexual meanings generated through the lived experience of women residing in Rafsanjan, a city in the Kerman province, where interviews and focus group discussions were conducted with 51 Iranian women. Content analysis was adopted to extract the meanings and perceptions. We categorized the findings into three aspects: sexual capacity, motivation, and performance. Sexual desire was the most important concept that women used when they were referring to their sexual capacity. Marriage was the main institution in which women’s motivation for sexual relationships and encounters resided, and “the priority of men’s sexual needs and characteristics” was identified as the core principle of marriage. The concept of sexual performance was more salient and tied to the husband’s sexual initiation. Analyzing the women’s narratives revealed that women’s sexual self-understandings and their sexual behaviors are strongly determined by “androcentricity”, this being relevant both to sexuality education and reproductive health. Recognition of this issue will facilitate understanding of the cultural foundations of sexuality among Iranians and help health providers in suggesting culturally appropriate and compatible forms of health care.     

进化心理学视角下的两性冲突与缓和

进化心理学观点认为两性冲突是一个性别达到最佳适应的过程被另一个性别所阻碍,其根本原因是两性繁衍成功的根本进化利益存在冲突。从进化心理学的角度,根据两性敌对性选择理论,两性冲突可以分为基因座内的两性冲突与基因座间的两性冲突,前者可由性选择理论解释,后者涉及到两性的适应与反适应以及在军备竞赛中的协同进化。而两性冲突缓和则可以由费舍尔模型与基因复制理论、性别二态性和一夫一妻制度解释。两性冲突及缓和也分别具有进化心理学的相关实证依据支持。未来两性冲突领域的研究需要提升研究方法的客观性及两性冲突特质的多样性,并关注两性冲突缓和的现实有效途径以及婚配制度与评估方式对繁衍成功的交互作用。     

Are Men and Women Really That Different? Examining Some of Sexual Strategies Theory (SST)��s Key Assumptions about Sex-Distinct Mating Mechanisms

Sexual Strategies Theory (SST; Buss and Schmitt 1993) suggests that, typically, men more so than women are more likely to spend proportionately more of their mating effort in short-term mating, lower their standards in short-term compared to long-term mating, feel reproductively constrained, and seek, but certainly not avoid, sex if pregnancy is likely in short-term relationships. A series of 4 survey studies each containing hundreds of college student participants from the western portion of the United States were conducted to test these hypotheses. The findings are inconsistent with SST but are consistent with Attachment Fertility Theory (AFT; Miller et al. 2005) that argues for relatively few evolved gender differences in mating strategies and preferences.     

Loneliness: Lost in the Landscape of Meaning

The present study is an examination of sex differences in the sources of annoyance that partners in close relationships might experience as a result of each other's behavior. To test hypotheses derived from S. E. Cross and L. Madson's (1997) self-construal theory and from D. M. Buss's (1989) evolutionary psychology-based model, men and women of varying ages and educational levels were asked to rate how annoyed they would be with each of 13 potentially annoying behaviors of their intimate partner. Results were consistent with self-construal theory in that relationship-threatening behaviors were more annoying to women than to men and autonomy threatening behaviors were more annoying to men than to women. Results were also consistent with evolutionary psychology in that aggressive behaviors were more annoying to women than to men and sexual withholding was relatively more annoying to men than to women. Sex differences in annoyance with relationship-threatening, autonomy-threatening, and reproductive strategy behaviors were independent of age and education level, although these factors did affect respondents' annoyance when partners were unemotional, sloppy, or pleased with their own appearance. Results showed that sources of annoyance in intimate relationships should not only be studied from an evolutionary perspective but from the perspectives of social, personality, and developmental psychology as well.     

Gender difference in emotional reactions and sexual coercion in casual sexual relations: An evolutionary perspective

This study tested four predictions derived from (evolutionary) sexual conflict theory. The central hypothesis was that men and women possess different emotional mechanisms that motivate and evaluate sexual activities. Women’s mechanisms are associated with their perception of partners’ ability and willingness to invest. For men these associations are weaker or inverse. Regression analyses of survey data from 194 college students revealed the following. As incidence of casual sexual relations increased (SOI Behavior), men reported less concern about partners’ intentions and less Worry–Vulnerability in response to casual sexual relations than women did; these gender interactions were significant. Regular sexual relations with partners with whom they did not desire emotional involvement showed the same pattern of gender differences. The Sexual Experiences Survey (SES) measured the incidence of sexual coercion in casual sexual relations. For women, but not for men, SOI Behavior was associated with all levels of sexual coercion. Limitations and implications are discussed.     

Sexual Motives: Cultural,Evolutionary, and Social Psychological Perspectives

Recently, scholars from a variety of disciplines have begun to investigate passionate love, sexual desire, and sexual behavior. Specifically, they have started to ask such questions as: “Why do young men and women engage in sexual liaisons?” “Why do they avoid such encounters?” Unfortunately, in attempting to answer such questions, scholars have generally focused on surveys and experiments within their own disciplines and have accorded scant attention to the discoveries of other disciplines. In this paper, we will begin by discussing three theoretical perspectives that have had the most to say about why young people seek out (or avoid) sex—cultural psychology, evolutionary psychology, and social psychology (where theorists often take a biopsychosocial approach). Then, we will (1) describe the many scales that have been used to assess sexual motives, and (2) review the multidisciplinary data which has been assembled in an attempt to answer the questions as to why people seek out (or avoid) sexual activity. Unfortunately, almost all this research was conducted by Western researchers, investigating the attitudes and behavior of young American men and women, who were heterosexual. (Alas, the wider-ranging data one would wish to consider is as yet only rarely available.) Through this multi-disciplinary synthesis, we hope to demonstrate the impact of culture, social experience, and biological imperatives in shaping young men’s and women’s motives for engaging in sexual encounters and provide a sort of “encyclopedia” of sexual motives measures and research for future scholars.     

拿破仑情结的进化：相对身高劣势和求偶动机对男性冒险行为的影响

研究以性选择理论为基础, 探讨了与同性竞争者的相对身高劣势和求偶动机对男性冒险行为的影响。4个研究一致显示, 与同性竞争者存在的身高劣势会导致男性提高自身冒险性; 且高求偶动机水平的男性, 会更多地表现出这种补偿性行为。这些结果提示, 拿破仑情结具有进化的基础, 男性在自身身高与竞争者相比处于劣势时, 采用冒险行为进行补偿是男性用以解决性内竞争和性间竞争问题的一种适应器。     

Personality and testosterone in men from a high-fertility population

Extraversion, a personality dimension associated with sociability, activity and dominance, predicts a man’s mating effort in various human populations. At a proximate level, individual differences in extraversion are likely to be mediated through testosterone, a strong hormonal correlate of men’s reproductive effort. However, the rare attempts to address this question have all been conducted in populations with low-fertility schedules, thus limiting the generality of the results. Using demographic, questionnaire and hormonal data from a high-fertility polygynous human population of Senegal, we first show that extraversion, a personality dimension predicting men’s mating behavior in this population, is associated with inter-individual differences in testosterone profiles, with men in the top quartile of extraversion distribution having 29% higher testosterone levels. We then show that personality profiles for neuroticism, openness and agreeableness are independent from testosterone levels. Since extraversion is the only personality dimension predicting men’s mating and reproductive success in this population, we suggest that variation in testosterone levels is primarily relevant for personality traits related to reproductive effort. The results have further implications to discuss possible evolutionary scenarios for the maintenance of variation in personality traits.     

人类“性交往”的进化

性交往是人类繁衍出现差异的进化“引擎”。现代人继承了祖先成功繁衍后代的性交往策略。这些策略涵盖长期守诺的性交往（如婚姻）、短期性交往（如短暂的外遇）、婚姻外的性交往（如不忠）、私通他人配偶（引诱别人的配偶）以及配偶维持（与单一配偶性交往）等。两性在性交往过程中面临不同的适应问题,性交往问题的进化机制存在极大的性别差异。配偶偏好不同、短期性交往的愿望不同以及性嫉妒的诱因不同等都是性交往具有性别差异的表现。很多实证研究都证实了性交往策略的存在,人类性交往研究是进化心理学研究中较为成熟的一个研究领域     

Snake mating systems, behavior, and evolution: the revisionary implications of recent findings

Sexual selection and mating systems profoundly influence the behavior and psychology of animals. Using their own studies of green anacondas (Eunectes murinus) and reviewing other recent studies, the authors conclude that incomplete data derived from a few well-studied snake species have led to general acceptance of polygyny as the dominant mating system in snakes. New data on behavior, paternity, and life history in a diverse taxonomic array of snakes support the view that polyandry is not only common in snakes but may have been the ancestral mating system. This interpretation helps to explain many seemingly paradoxical behavioral differences between lizards and snakes, such as the lack of territorial systems in most snakes and their frequent female-biased sexual size dimorphism.     

Subjective Distress to Violations of Trust in Mexican American Close Relationships Conforms to Evolutionary Principles

Sex differences in subjective distress to violations of trust in a close relationship were observed among Mexican American men and women. Imagining a partner’s emotional infidelity and other female-linked violations (for example, a partner who no longer desires to work) distressed a larger percentage of women than men. In contrast, imagining a partner’s sexual infidelity and other male-linked violations (for example, a partner who no longer makes an effort to look physically attractive) distressed a larger percentage of men than women. The results from two studies provided compelling evidence against a social–cognitive explanation of the sex differences and for an evolutionary psychology explanation based on men and women responding to threats to their sex-linked mating strategies.     

Sources of annoyance in close relationships: sex-related differences in annoyance with partner behaviors

The present study is an examination of sex differences in the sources of annoyance that partners in close relationships might experience as a result of each other's behavior. To test hypotheses derived from S. E. Cross and L. Madson's (1997) self-construal theory and from D. M. Buss's (1989) evolutionary psychology-based model, men and women of varying ages and educational levels were asked to rate how annoyed they would be with each of 13 potentially annoying behaviors of their intimate partner. Results were consistent with self-construal theory in that relationship-threatening behaviors were more annoying to women than to men and autonomy threatening behaviors were more annoying to men than to women. Results were also consistent with evolutionary psychology in that aggressive behaviors were more annoying to women than to men and sexual withholding was relatively more annoying to men than to women. Sex differences in annoyance with relationship-threatening, autonomy-threatening, and reproductive strategy behaviors were independent of age and education level, although these factors did affect respondents' annoyance when partners were unemotional, sloppy, or pleased with their own appearance. Results showed that sources of annoyance in intimate relationships should not only be studied from an evolutionary perspective but from the perspectives of social, personality, and developmental psychology as well.     

Sex differences in the events that elicit jealousy among homosexuals

When individuals are asked which event would upset them more—a partner's emotional infidelity or a partner's sexual infidelity—among heterosexuals more men than women select a partner's sexual infidelity as the most distressing event, whereas more women than men select a partner's emotional infidelity as the most upsetting event. Because homosexuals’mating psychology is unlike that of heterosexuals, the present study examined which of these two events is more upsetting in a sample of 237 Dutch homosexuals. In support of our hypothesis it was found that, whereas gay men more often than lesbian women chose a mate's emotional infidelity as the most upsetting event, lesbians more often than gay men chose a mate's sexual infidelity as the most upsetting event. In addition, analyses showed that the effect of participant sex on infidelity choice was mediated by beliefs with regard to the co‐occurrence of sexual and emotional infidelity. Apparently, with respect to choosing the most upsetting type of infidelity of their partner, homosexuals resemble heterosexuals of the opposite sex. Several explanations are discussed for this finding.
