Sex differences on a measure of conformity in automated teller machine lines

Sex differences in conformity were examined as participants approached two ATMs, one of which was occupied by three confederates and the other immediately available. The number of men and women in the line in front of one of the ATMs was manipulated (3 men or 3 women), and an unobtrusive observer recorded the sex of each participant. The results indicated that women were more likely than men to wait in line to use the ATM regardless of the makeup of the line. Thus, the present study provides evidence in favor of the idea that sex differences in conformity are evident on a common task performed in a natural setting.     

Sex differences in confidence influence patterns of conformity

Lack of confidence in one's own ability can increase the likelihood of relying on social information. Sex differences in confidence have been extensively investigated in cognitive tasks, but implications for conformity have not been directly tested. Here, we tested the hypothesis that, in a task that shows sex differences in confidence, an indirect effect of sex on social information use will also be evident. Participants (N = 168) were administered a mental rotation (MR) task or a letter transformation (LT) task. After providing an answer, participants reported their confidence before seeing the responses of demonstrators and being allowed to change their initial answer. In the MR, but not the LT, task, women showed lower levels of confidence than men, and confidence mediated an indirect effect of sex on the likelihood of switching answers. These results provide novel, experimental evidence that confidence is a general explanatory mechanism underpinning susceptibility to social influences. Our results have implications for the interpretation of the wider literature on sex differences in conformity.     

Sex differences in comments made during conflict within close heterosexual pairs

Questionnaires were used to investigate (1) stereotypes about what young couples do and say during their conflicts and (2) reports (by actual young couples) of what each one is likely to do or say. The two sets of data yielded much the same pattern of results. The female is expected and reported to cry and sulk and to criticize the male for lack of consideration of her feelings and for insensitivity to his effect on her. The male is expected and reported to show anger, to reject the female's tears, to call for a logical and less emotional approach to the problem, and to give reasons for delaying the discussion. The Study I expectations for sex differences during conflict are held to about the same degree by the female and male respondents. In both studies, the differences were found to depend primarily on sex of the person and not on the particular problem involved in the conflict. The results are interpreted in terms of the interaction between a conflict-avoidant person (the male) and his partner (the female), who is frustrated by the avoidance and asks that the problem and the feelings associated with it be confronted.     

Sex differences in semantic language processing: a functional MRI study

Predictions based on two models of sex differences in cerebral organization of language were compared by examining fMRI patterns of 10 females and 9 males during a semantic processing task. Both groups displayed activation of left inferior frontal gyrus (IFG), left superior temporal gyrus (STG), and cingulate. Females, but not males, showed bilateral IFG and STG activation. Further analyses revealed females had less diffuse left activation and greater right posterior temporal and insula region activation than males. Results support both an interhemispheric and an intrahemispheric model of sex differences in language, suggesting that the models may not be mutually exclusive.     

Sex differences in attribution: A Norwegian study

A quasi-experimental study was conducted to examine the effect of sex on actor and observer attributions of success and failure. It was predicted that, contrary to American results in similar studies, Norwegian males and females would tend to be largely similar in their attribution of success and failure. Only same-sex attributions were explored. Subjects were asked to attribute causality along a set of six standard causal dimensions. The results showed that sex had a relatively minor effect on attributions, compared to the effects of attributor role and task outcome. Only in their attributions of ability did men and women differ to some degree in that women were more likely to use lack of ability as an explanation for own failure. The study concludes that cross-cultural research is needed in order to better assess the normative impact on attribution.     

Sex differences in impulsivity: a meta-analysis

Men are overrepresented in socially problematic behaviors, such as aggression and criminal behavior, which have been linked to impulsivity. Our review of impulsivity is organized around the tripartite theoretical distinction between reward hypersensitivity, punishment hyposensitivity, and inadequate effortful control. Drawing on evolutionary, criminological, developmental, and personality theories, we predicted that sex differences would be most pronounced in risky activities with men demonstrating greater sensation seeking, greater reward sensitivity, and lower punishment sensitivity. We predicted a small female advantage in effortful control. We analyzed 741 effect sizes from 277 studies, including psychometric and behavioral measures. Women were consistently more punishment sensitive (d = -0.33), but men did not show greater reward sensitivity (d = 0.01). Men showed significantly higher sensation seeking on questionnaire measures (d = 0.41) and on a behavioral risk-taking task (d = 0.36). Questionnaire measures of deficits in effortful control showed a very modest effect size in the male direction (d = 0.08). Sex differences were not found on delay discounting or executive function tasks. The results indicate a stronger sex difference in motivational rather than effortful or executive forms of behavior control. Specifically, they support evolutionary and biological theories of risk taking predicated on sex differences in punishment sensitivity. A clearer understanding of sex differences in impulsivity depends upon recognizing important distinctions between sensation seeking and impulsivity, between executive and effortful forms of control, and between impulsivity as a deficit and as a trait.     

Sex differences in online shopping: an exploratory study

Empirically, predictors of purchasing an item (among 15) online in a sample of 365 undergraduates were dependent upon the sex of the purchaser and the particular item purchased.     

Sex differences in educational outcomes: A cross-national study

Through their organization and curricula, schools either promote separate roles for males and females or operate to minimize differences. This study describes sex differences in science and reading achievement and attitudes for nationwide samples of 14-year-old children in the United States, Sweden, and England. There are largely the same sex differences in all three countries: Male and female pupils have similar reading skills, while girls have more positive reading habits; males outperform females in science, with the smallest difference observed for biology; males have more positive attitudes toward science, except that females believe science to be at least as important a topic as boys do. There is no noteworthy increase in sex distinctions with one more year of schooling, from grade 8 to grade 9. However, in English coeducational schools, girls show a deceleration in science and vocabulary achievement relative to their male peers. Girls in English one-sex schools exceed their male counterparts in reading and several science subjects. It is hypothesized that the role of successful female teachers and peers, and the absence of social pressure from boys, may facilitate girls' learning in these areas. A study is proposed of specific school practices and the ways in which they determine sex discrepancies.An earlier version of this article was presented to the annual meeting of the American Educational Research Association, San Francisco, April 1976.

Sex differences in historical knowledge and school grades: a 26 nation study

Sex differences among ninth grade school students in historical knowledge and grades were examined in 29 samples drawn from 26 countries. Boys obtained higher mean scores on the tests of historical knowledge in all samples, while girls obtained better grades in 22 of the samples.     

Sex differences in self-disclosure: a meta-analysis.

A meta-analysis of 205 studies involving 23,702 Ss was conducted to determine whether there are sex differences in self-disclosure. Across these studies, women disclosed slightly more than men (d = .18). This effect size was not homogeneous across studies. Several moderator variables were found. Sex of target and the interaction effect of relationship to target and measure of self-disclosure moderated the effect of sex on self-disclosure. Sex differences in self-disclosure were significantly greater to female and same-sex partners than to opposite-sex or male partners. When the target had a relationship with the discloser (i.e., friend, parent, or spouse), women disclosed more than men regardless of whether self-disclosure was measured by self-report or observation. When the target was a stranger, men reported that they disclosed similarly to women; however, studies using observational measures of self-disclosure found that women disclosed more than men.     

Sex differences in romantic attachment: a meta-analysis

This article presents the first meta-analysis of sex differences in the avoidance and anxiety dimensions of adult romantic attachment, based on 113 samples (N = 66,132) from 100 studies employing two-dimensional romantic attachment questionnaires (Experiences in Close Relationships, Experiences in Close Relationships-Revised, and Adult Attachment Questionnaire). Overall, males showed higher avoidance and lower anxiety than females, with substantial between-study heterogeneity. Sex differences were much larger in community samples (bivariate D = .28) than in college samples (D = .12); web-based studies showed the smallest sex differences (D = .07) in the opposite direction. Sex differences also varied across geographic regions (overall Ds = .10 to .34). Sex differences in anxiety peaked in young adulthood, whereas those in avoidance increased through the life course. The relevance of these findings for evolutionary models of romantic attachment is discussed, and possible factors leading to underestimation of sex differences are reviewed.     

Sex differences: A study of the ear of the beholder

Male and female adult Ss, while performing an unrelated task, heard a single infant awakening. The infant was labeled a girl or a boy. The dependent variable was how quickly Ss responded to the crying infant. Females responded more quickly to the girl than to the boy. Males responded equally slowly to boy and girl. A questionnaire on sex differences in fragility showed that females and males tend to disagree with the proposition that girls are more fragile than boys. Thus, the females' faster response to a crying girl cannot be accounted for by a belief in sex-differential fragility. Correlations between fragility beliefs and response times to an infant indicate that sex-differential belief-behavior relationships are not the same for males and females.     

Sex differences in physical,verbal, and indirect aggression: A review of recent research

In the present article, recent research on sex differences in aggressive styles is reviewed. The concept of indirect aggression is particularly presented and discussed. It is argued that it is incorrect, or rather, nonsensical, to claim that males are more aggressive than females. A theory regarding the development of styles of aggressive behavior is presented.     

Sex differences in verbal fluency: a short note

Adult male and female subjects performed two fluency tasks from the 'Kit of Reference Tests for Cognitive Factors'. Although both word fluency and ideational fluency are said to show female superiority, a significant difference in favour of females could be found only in the task which primarily requires lexical access and not in the task requiring mental access to colour and form of objects.
