Sex differences in cooperation: a meta-analytic review of social dilemmas

Although it is commonly believed that women are kinder and more cooperative than men, there is conflicting evidence for this assertion. Current theories of sex differences in social behavior suggest that it may be useful to examine in what situations men and women are likely to differ in cooperation. Here, we derive predictions from both sociocultural and evolutionary perspectives on context-specific sex differences in cooperation, and we conduct a unique meta-analytic study of 272 effect sizes-sampled across 50 years of research-on social dilemmas to examine several potential moderators. The overall average effect size is not statistically different from zero (d = -0.05), suggesting that men and women do not differ in their overall amounts of cooperation. However, the association between sex and cooperation is moderated by several key features of the social context: Male-male interactions are more cooperative than female-female interactions (d = 0.16), yet women cooperate more than men in mixed-sex interactions (d = -0.22). In repeated interactions, men are more cooperative than women. Women were more cooperative than men in larger groups and in more recent studies, but these differences disappeared after statistically controlling for several study characteristics. We discuss these results in the context of both sociocultural and evolutionary theories of sex differences, stress the need for an integrated biosocial approach, and outline directions for future research.     

Cooperation Induces an Increase in Emotional Response,as Measured by Electrodermal Activity and Mood

Humans need social interaction with others for survival. Competition and cooperation are two somewhat opposed interpersonal strategies that help us to achieve both individual and shared aims and objectives. The aim of this research was to study whether autonomic activity is a good indicator of emotional activation in response to social interaction (cooperation, competition) or working alone, considering gender and outcome obtained in tasks (positive or negative) as moderating variables. We tested electrodermal activity (EDA) and mood before, during and after social (cooperation, competition) or working alone in men (64) and women (60), young-adult students from the University of Valencia. Higher EDA was observed in individuals taking part the cooperative than the competitive task. Further, men who competed showed lower SCLs than men who performed the other type of task. In contrast, women who cooperated demonstrated lower NSCRs than women who competed and men who cooperated. Participants with negative outcomes and women were found to have worse mood states. Our results may be generalizable to situations in which negotiation, mediation and cooperative strategies are relevant for decision making and/or problem solving.     

Change and Stability in Active and Passive Social Influence Dynamics during Natural Drinking Events: A Longitudinal Measurement-Burst Study

We examined the link between social norms and active social influences occurring during natural social drinking contexts. Across 4 yearly measurement-bursts, college students (N = 523) reported daily for 30-day periods on drinking norms, drinking offers, how many drinks they accepted, and personal drinking levels during social drinking events. In contexts where drinking norms were higher, students were more likely to both receive and comply with drinking offers. These acute social influences were highly stable throughout college, but affected men and women differently across time: Women received more drinking offers than men, especially at the beginning of college and when norms were higher, but men complied with more drinking offers per occasion. These effects were not attributable to between-person differences in social drinking motives or drinking levels, nor to within-person patterns of situation-selection. The present work suggests that context-specific drinking norms catalyze active social influence attempts, and further promote compliance drinking.     

WHO CONSIDERS THEMSELVES VICTIMS OF DISCRIMINATION?

We focus on the general issue of how and why individuals might decide if they have been victims of gender discrimination and how social status differences between women and men may change the significance of experiencing gender discrimination. Because both self-protective and situational factors have been found to influence interpretation of prejudicial events, in the present study we explore several individual-difference factors that might differentially predict perceived gender discrimination in women and men. We found that, for men, low self-esteem and high personal assertiveness were related to higher ratings of personal discrimination. Low self-esteem was also related to men's perceptions of discrimination against men as a group. For women, high need for approval was negatively related to perceptions of personal discrimination whereas depression was positively related. Depression was also related to higher ratings of discrimination against women, as was feminism. We argue that perceptions of discrimination serve different purposes for structurally privileged and disadvantaged groups.     

Referees' Decision Making in Handball and Transgressive Behaviors: Influence of Stereotypes About Gender of Players?

We offer norm theory as a framework for developing some common ground within both feminist psychology and lesbian and gay psychology about the meaning of empirical differences between social groups. Norm theory is a social cognitive theory that predicts that empirical differences will be consistently explained by taking more typical groups (e.g., men, straight people) as implicit norms for comparison and by attributing differences to less typical groups (e.g., women, lesbians, and gay men). Results of an experiment (N = 114) are presented to show that norms shape interpretations of empirical differences between lesbian/gay and straight persons by (1) leading explanations to focus on attributes of lesbian/gay persons, and (2) leading to judgments that straight persons have less mutable attributes. Stereotypes also affected interpretations; stereotype-consistent results led to more essentialistic explanations and, when targets were female, to higher ratings of the results' importance and fundamentality. We highlight how experiments can be used to understand the process of constructing the meaning of scientific data, and make recommendations for empiricists' interpretive practices and constructionist theories in feminist psychology and lesbian and gay psychology.     

Gender,Interdependent Self-construals,and Collective Self-esteem: Women and Men Are Mostly the Same

Women and men may differ in how they define themselves in reference to their social world. Baumeister and Sommer () suggest that women prefer close relationships whereas men prefer large-group memberships. We examined how this hypothesized gender difference relates to collective self-esteem from three interdependent groups: friends, family, and gender. Study 1 revealed that women and men report equivalent levels of collective self-esteem from both relational and collective groups. Study 2 replicated this finding, and further revealed that the importance of group membership to individuals is more crucial to understanding collective self-esteem than is a gender differences approach. We discuss the implications of these results in terms of contingencies of social self-worth and potential cognitive processes involved in self-construal.     

Fixed Roles and Situated Actions

Two visions have shaped research and theory on gender for at least 60 years. The older vision treats the genders as distinct roles that are strongly socialized and make women and men inherently different in all circumstances. The newer one treats gender as reflecting effects of different social structural relations, and it sees women and men as capable of displaying wide-ranging and overlapping responses. We clarify the two visions by stating five tenets of each. The visions affect a scholar’s choice of research topics, what one sees when women and men interact, the meanings attached to different behaviors and attitudes, how one interprets evidence, and how to know when a research question has received a satisfactory answer.     

Culture, gender, and the self: variations and impact of social comparison processes

Psychological differences between women and men, far from being invariant as a biological explanation would suggest, fluctuate in magnitude across cultures. Moreover, contrary to the implications of some theoretical perspectives, gender differences in personality, values, and emotions are not smaller, but larger, in American and European cultures, in which greater progress has been made toward gender equality. This research on gender differences in self-construals involving 950 participants from 5 nations/cultures (France, Belgium, the Netherlands, the United States, and Malaysia) illustrates how variations in social comparison processes across cultures can explain why gender differences are stronger in Western cultures. Gender differences in the self are a product of self-stereotyping, which occurs when between-gender social comparisons are made. These social comparisons are more likely, and exert a greater impact, in Western nations. Both correlational and experimental evidence supports this explanation.     

Inhibitory control and empathy-related personality traits: sex-linked associations

We here report two studies exploring associations between inhibitory control (measured with the Sustained Attention to Response Task, SART) on the one hand, and self-reports of trait cooperativeness and empathy on the other. A coherent picture was obtained in women whose inhibitory control proficiency predicted higher scores on the Temperament and Character Inventory Cooperativeness and a higher Empathy Quotient. Individual differences in working memory did not predict self-reported empathy. In men, the association between SART performance and empathy was less clear: Good performance on the inhibitory task predicted lower scores on Cooperativeness and was unrelated to the Empathy Quotient. In both studies, women outperformed men on the SART. The results in women may reflect how individual differences in elemental neuro-cognitive operations such as inhibitory control influence more complex functions such as social cognition.     

Divorce and the Multidimensionality of Men and Women’s Mental Health: The Role of Social-Relational and Socio-Economic Conditions

Research consistently reveals that the divorced generally face more mental health problems than the married. Less attention however has been paid to positive mental health indicators. Insight in these however may help policy makers and care providers to see both the broader picture and stimulate active coping. Using data from the European Social Survey (2006–2007), differences in both feelings of depression, and in feelings of self-esteem, autonomy, and competence between the married (N?=?14,072) and divorced (N?=?4,304) are estimated for women and men separately. Drawing on stress and coping theories, we map how specific social-relational and socio-economic conditions relate. Analyses reveal that divorce is related not only to more feelings of depression, but also to lower levels of self-esteem and competence. Difference scores in mental health based on marital status are also found to differ significantly between men and women for competence, with the difference being more pronounced in men. Additionally, social-relational and socio-economic conditions explain much of the gap in depression scores—and to a lesser extent, in self-esteem and competence scores—between the married and divorced. Finally, some interesting gender differences were found in how social-relational and socio-economic conditions relate to mental health when divorced, with women especially seeming to benefit from advantageous socio-economic conditions.     

How daydreaming relates to life satisfaction, loneliness, and social support: the importance of gender and daydream content

Daydreaming appears to have a complex relationship with life satisfaction and happiness. Here we demonstrate that the facets of daydreaming that predict life satisfaction differ between men and women (Study 1; N=421), that the content of daydreams tends to be social others (Study 2; N=17,556), and that who we daydream about influences the relation between daydreaming and happiness variables like life satisfaction, loneliness, and perceived social support (Study 3; N=361). Specifically, daydreaming about people not close to us predicts more loneliness and less perceived social support, whereas daydreaming about close others predicts greater life satisfaction. Importantly, these patterns hold even when actual social network depth and breadth are statistically controlled, although these associations tend to be small in magnitude. Individual differences and the content of daydreams are thus important to consider when examining how happiness relates to spontaneous thoughts.     

Gender bias in caregiving professions: The role of perceived warmth

One hypothesized reason for why a disproportionately low number of men enter caregiving fields is how such men are perceived. In two studies, drawing upon the Stereotype Content Model and the lack‐of‐fit model, we tested whether men would encounter more social (e.g., likeability bias) and economic (e.g., hiring or job opportunity bias) penalties than women in caregiving professions due to perceptions that men are less warm than women. In all three studies, we created job or employment materials in which the gender of the candidate or employee was manipulated. In Study 1, a female preschool teacher received higher warmth ratings than a male preschool teacher, which in turn predicted preference for the female teacher over the male teacher. In Study 2, a female social worker was rated more highly in warmth and job hireability than a male social worker; warmth also mediated the relationships between gender and both likeability and job hireability. In Study 3, a male preschool teacher was rated lower in warmth, likeability, job hireability, and job suitability than both a female preschool teacher and a preschool teacher with an unspecified gender. There were no differences between perceived competence of men and women in caregiving positions when competence was assessed. Implications for the factors that predict adverse reactions to and penalties against men in caregiving occupations, as well as interventions to combat the potential negative effects of such penalties on men's interest in caregiving careers, are discussed.     

“May I present you: my disgust!” – Declared disgust sensitivity in the presence of attractive models

Disgust sensitivity differs among men and women, and this phenomenon has been observed across numerous cultures. It remains unknown why such sex differences occur, but one of the reasons may relate to differences in self-presentation. We tested that hypothesis in an experiment comprising 299 participants (49% women) randomly allocated into three groups. Each group completed the Three Domains Disgust Scale (TDDS) and rated how disgusting they found olfactory, visual, gustatory, and tactile disgust elicitors either when a male experimenter was present, a female experimenter was present, or no experimenter was present. We hypothesised that male participants in the female experimenter group would declare decreased levels of disgust sensitivity, and female participants in the male experimenter group would declare increased levels of disgust sensitivity. Results showed that despite sex differences in pathogen and sexual disgust, attractive experimenters did not evoke any differences in declared disgust across groups with one exception–both men and women self-presented as more sensitive to sexual disgust in the presence of the female experimenter. We discuss our findings in the light of evolutionary and social theories.     

Sex Differences in the Presentation of Chronic Low Back Pain

Sex differences in 351 patients with chronic low back pain were examined. Biological, psychological, and psychosocial factors were considered. Sex differences in adaptive functioning were consistent with traditional gender roles. Significant interactions were found for sex and employment status, and sex and marital status. Retired women reported more pain and less activity than retired men. Retired men reported the least pain of any group. Outdoor work and social activities show opposite within–group patterns for men and women when stratified by employment status. Marriage was associated with more household work for women and less for men. The financial and social contexts of employment status and marriage are different for men and women. Results suggest the treatment of women with chronic low back pain requires attention to work in the home and the financial and social context of work outside the home.     

Gender differences in evaluating social-sexual conduct in the workplace

Qualitative interviews exploring gender differences in perceptions of sexual harassment were conducted with 100 full-time St. Louis area employees. Women more than men reported that telling dirty/sexual jokes was a non-harassing behavior, qualified behaviors as harassing when they happened in the workplace, and considered behaviors as non-harassing when the man's intentions were not harmful. Men more than women reported that requesting a date was a non-harassing behavior, qualified behaviors as harassing when the woman did not welcome the behavior, and considered behaviors as non-harassing when they did not violate workplace norms. Logistic regression analysis predicted the respondent gender with 86% accuracy. Finally, concept mapping suggested that when women think about harassers they are concerned with power and social aptitude, while men seem to be more concerned about the responsibility and psychological adjustment of perpetrators of sexual harassment. When women think about victims of harassment they are concerned with a woman's assertiveness and work effectiveness, while men are more concerned with the psychological state of the woman and how provocative she is when they think about victims of sexual harassment.     

Gender and social support: Taking the bad with the good?

In examining past research, a paradox can be found in the relationships between gender, social support, and depression. Although women report higher levels of depression than men, they also generally report more social support—a factor found to reduce depressive symptoms. In efforts to explain this seeming inconsistency, it was hypothesized that women report both more support and more depression because they are more likely than men to experience both positive and negative aspects of social relationships. Based on a community sample of predominantly Caucasian respondents, findings indicate that greater perceived support among women can be explained by more frequent contact with network members and a tendency to possess relationships characterized by greater intimacy, emotional disclosure, and empathy. However, women also report more frequent negative interactions with network members and are more adversely affected by marital conflict than are men. While negative interactions and conflict cannot account for gender differences in depression, they do help to explain how women can experience both more support and more depression. Among women, the health-enhancing effects of support on depression may be balanced by the detrimental effect of conflict.     

GENDER, JEALOUSY, AND REASON

Abstract— Research has suggested that men are especially bothered by evidence of their partner's sexual infidelity, whereas women are troubled more by evidence of emotional infidelity. One evolutionary account (Buss, Larsen, Westen, & Semmelroth, 1992) argues that this is an innate difference, arising from men's need for paternity certainty and women's need for male investment in their offspring. We suggest that the difference may instead be based on reasonable differences between the sexes in how they interpret evidence of infidelity. A man, thinking that women have sex only when in love, has reason to believe that if his mate has sex with another man, she is in love with that other. A woman, thinking that men can have sex without love, should still be bothered by sexual infidelity, but less so because it does not imply that her mate has fallen in love as well. A survey of 137 subjects confirmed that men and women do differ in the predicted direction in how much they think each form of infidelity implies the other, proposing innate emotional differences may, therefore, be gratuitous.     

Making Gender Comparisons More Meaningful: A Call for More Attention to Social Context

We challenge researchers to consider sex and gender as a marker for possible social contextual differences. Disappointed by both philosophical and empirical attempts to find coherence in research making gender comparisons, we selectively review studies showing both context-specific similarities between women and men where overall comparisons found differences as well as context-specific differences where general patterns of similarity existed. These examples cut across embedded levels of social context, ranging from those immediately proximal to the individual (interpersonal) to organizational and broad societal structures. They suggest that seemingly identical contexts can have sweepingly different impacts on women and men and that effective social interventions be gender-sensitive.     

TWO ROUTES TO ELIMINATING GENDER DIFFERENCES IN PERSONAL ENTITLEMENT: Social Comparisons and Performance Evaluations

This analog study examined how the presence and absence of explicit social comparison standards and performance feedback influenced women's and men's perceptions of personal entitlement for pay. In the absence of both comparison information and performance feedback, women felt they deserved less pay than did men. However, these gender differences were eliminated when women and men were exposed to either the same comparison information or the same performance feedback. Path analyses further revealed that the effects of comparison information and performance feedback on judgments of pay fairness and satisfaction were mediated almost exclusively by feelings of entitlement.     

Structural gender differences in perceived social support

Gender is an important influence on support-relevant social interactions, however findings of studies on gender differences in social support are not definitive. Although differences between men and women in the various social support measures have been found in numerous studies, neither the cause nor the explanatory process is known. This study examines gender differences in the dimensionality of social support. A large sample (N=3210) from the general population of women (60%) and men aged between 18 and 65 years old (Mean AGE=34.1) responded to a brief scale with items assessing the distinct functions of the perceived availability of social support. Confirmatory factor analyses yielded one factor in the women's sample that measures global social support perceived, and two in the men's. The first factor in the men's sample measures emotional support (providing empathy, caring, validation of self-worth), and the second measures instrumental support (e.g. practical assistance or financial aid). We concluded that there are gender differences in the structure of perceived social support and that these differences can be explained by socialization experiences and social roles associated with gender.
