The Gender Gap in Advanced Math and Science Course Taking: Does Same-Sex Education Make A Difference?

A large representative sample (N?=?20,816) of Israeli Jewish high school students served to explore differences between coeducational and same-sex schools in advanced math and science courses. Data were obtained from the Israeli population census of 1995 and from the Israeli Ministry of Education. Results from logistic regressions suggest that girls at all-female state religious schools did not differ from girls at coeducational state schools in placement in advanced math, physics and biology courses. But girls at all-female religious schools took advanced computer science courses at a much higher rate than girls at coeducational schools. This finding is attributed to a different curricular policy and not directly to the all-female environment.     

Goal-striving and the implementation of goal intentions in the regulation of body weight

Abstract

The enactment of relatively easy-to-implement and relatively difficult-to-implement goal intentions was investigated in a field study of body weight maintenance for 141 university students. Three appraisal processes were examined as mechanisms for implementing intentions: self-efficacy, outcome expectancy, and affect towards means. The results showed that goal-directed dieting behaviours for men and women and goal-directed exercising/sport activities for men were influenced by the appraisals in a linear compensatory manner, and goal-directed exercising/sport activities for women were influenced by the appraisals via a three-way interaction. Self-efficacy, in particular, was a strong, pervasive determinant of both dieting and exercising/sport activities for men and women.     

SINGLE-SEX VERSUS MIXED-SEX CLASSES AND GENDER SCHEMATA IN CHILDREN AND ADOLESCENTS

Positive effects for women and girls of all-female schools have been proposed, although there is relatively little clear empirical support for these beneficial results. Much of the cited research is based on elite all-female institutions or on parochial schools. This study takes advantage of the change of a private, nonparochial school from all girls to both sexes. Longitudinal data from grades 2 through 12 were collected over the course of the academic year to study the results of this transition. Stereotyping declined with age and over time in both types of class-rooms. Girls in single-sex classrooms showed some tendency to be more stereotyped in their perceptions of mixed-sex classrooms than did the girls who were actually in that setting. Thus, none of the measures showed any significant increase over time in stereotyping among girls in mixed-sex classes. Implications of these findings are discussed.     

The double standard of aging and the social situation: Judgments of attractiveness of the middle-aged woman

Two hundred male and 200 female undergraduates judged pictures of middle-aged women and middle-aged men for their immediate emotional appeal. Pictures had been selected to be of middle attractiveness and to represent individuals who appeared to be between 35 and 55 years old. Subjects made judgments under one of the following social conditions: in private, or in small groups which were all male, all female, or half male and half female. Social condition and subjects' sex affected judgments significantly, and there were some significant complex interactions between these two variables and the sex of the stimulus picture. Male and female subjects privately judged middle-aged women to be more attractive than middle-aged men, but the effect was reversed when judgments were made publicly in groups. As predicted, members of all-male groups judged middle-aged women to be considerably less attractive than middle-aged men. Members of all-female groups, and both the men and the women in mixed-sex groups, judged middle-aged women to be only slightly less attractive than middle-aged men.The authors wish to thank Linda Andrews, Dayna Buskirk, Anne Grealy and Lori Monda for their assistance.     

Are women invisible as leaders?

This study shows that women are unlikely to be seen as leaders. Subjects (n=448) rated each member of a five-person group (shown in a photograph) on leadership attributes and also chose one of the five as “contributing most to the group.” Eight different stimulus slides were used. In two slides the “head-of-the-table” cue to group leadership was pitted against sex-role stereotypes. A man seated at the head of the table in a mixed-sex group was clearly seen as leader of his group, but a woman occupying the same position was ignored. The head-of-the-table cue identified women as leaders only in all-female stimulus groups. The data were consistent with the hypotheses that sex stereotypes still control social judgments, and that discrimination operates nonconsciously and in spite of good intentions.     

Behavioral and psychological implications of body dissatisfaction: Do men and women differ?

The relationships of body satisfaction, self-esteem, dieting, and exercise were studied in 92 men and women. Men and women did not differ in degree of body dissatisfaction as assessed by three different measures. However, on the direction of body dissatisfaction, men were as likely to want to be heavier as thinner, whereas virtually no women wished to be heavier. Although overall body esteem was correlated with self-esteem for both men and women, measures of weight dissatisfaction were not associated with self-esteem for women. The normative nature of weight dissatisfaction for women today may serve to buffer its effects on self-esteem. Women reported exercising for weight control more than men, and exercising for weight control was associated with disregulated eating.     

The relationship between exercise motives and psychological well-being

The aim of the present study was to use the self-determination model of exercise motives to examine the relationship between extrinsic and intrinsic motives for exercise and a number of measures of psychological well-being. Undergraduate students purporting to exercise regularly (N = 227; 102 men, 125 women) were split into 2 groups: those exercising for less than 6 months and those exercising for 6 months or more. The respondents were asked to complete measures of exercise motivation, self-esteem, psychological well-being, and stress. Among individuals exercising for less than 6 months, a number of extrinsic motivations for exercise were significantly related to poorer psychological well-being. Among individuals exercising for 6 months or more, a number of intrinsic motivations were significantly related to better psychological well-being. The present findings suggest that researchers can use self-determination theory to understand the relationship between exercise motivation and psychological well-being.     

Person–Environment Interaction in a New Secure Forensic State Psychiatric Hospital

This study examined the person–environment interaction effects of environmental design on ward climate, safety, job satisfaction, and treatment outcomes within a new high security forensic psychiatric facility. Participants included male and female adult psychiatric inpatients and staff members at different security stages. Data were collected once before and twice after the experimental group moved into the new building. The control group remained in the same facilities. Contrary to expectations, the new building had limited effects on the measured variables. Copyright © 2014 John Wiley & Sons, Ltd.     

Sex composition and group performance in a visual signal detection task

Forty-eight Ss (24 males, 24 females) were run in groups of 4 on 720 trials of a 16-alternative forced-choice visual signal detection task requiring both individual and group decisions. Four types of groups were formed: all male, all female, mixed-alternate (seated in the order male-female-male-female), and mixed-adjacent (seated in the order male-male-female-female). There were no differences in performance between all-male and all-female groups, but mixed-sex groups had poorer performance, with mixed-adjacent groups having significantly lower sensitivity than homogeneous-sex groups. The results were interpreted as indicating that heterogeneity of groups with regard to sex interacts with seating pattern in affecting performance, probably due to the formation of information coalitions between like-sex group members when the seating pattern encourages such coalitions.     

Transient cardiac responses to witnessing horrible events in young adult female exercisers and non-exercisers

ObjectivesIt has been proposed that regular exercisers may be less vulnerable to the effects of stress and better able to cope with aversive events than people who are sedentary, but findings have not been consistent. In the present study, physiological variables indicating specific relevant psychological processes were used to objectively assess women's responses to stressful events.Design and MethodNon-exercising (n = 56) and regularly exercising women (up to 4 h, n = 62, and more than 4 h per week, n = 50) were viewing an aversive film consisting of scenes of real injury and death, and their transient cardiac responses to sudden horrifying events happening to persons in the film were obtained, as well as changes of prefrontal-posterior coupling, measured by EEG.ResultsCompared to regularly exercising women, non-exercising women showed a clearly more pronounced second accelerative component of the transient heart rate response to the terrifying events, indicating greater sensitivity of the avoidance (defensive) motivational system and heightened sensitivity to aversive stimuli. Moreover, non-exercising women did not show the expected characteristic initial heart rate acceleration when the scene approached its fatal end, that is, more rigid responding, and EEG data indicated less susceptibility to affect-laden information at the perceptual level.ConclusionsThe findings support the notion of less adaptive coping with adverse events in sedentary compared to exercising women and add to the growing evidence suggesting a stress-buffering effect of regular exercise, therefore promoting resilience and resistance to the negative impact of stressor and trauma exposure.     

Communication Using Camera Phones Among Young Men and Women: Who Sends What to Whom?

This study examined whether the gender of the sender and recipient would influence camera phone usage. 180 college and university students from the Midlands and North of England provided information on communication with friends and family, and on personal importance of image uses. A sub-sample of 130 provided further data on likelihood of sending different kinds of image and the content of recent images sent and received. Many gender similarities were found, together with evidence of the use of images to support heterosexual relationships. However, the results showed greater use of images of significant individuals by the women than among their male counterparts, among all-female dyads and to communicate with female recipients. Overall the results suggest that women use images more than men for relationship maintenance.     

Does the level of physical exercise affect physiological and psychological responses to psychosocial stress in women?

ObjectivesTo test the Cross-Stressor Adaptation hypothesis for females by examining whether physically exercising young women show reduced physiological and psychological stress responses to a psychosocial stressor.DesignForty-seven healthy young women with different levels of physical exercise (17 not or rarely exercising, 15 moderately exercising, 15 vigorously exercising) underwent the Trier Social Stress Test for Groups (TSST-G); physiological and psychological stress responses during and after stress induction were compared.MethodANOVAs with repeated measures were used to compare stress reactivity and recovery between the three exercise groups. Heart rate and salivary free cortisol were used as indicators of physiological stress response, state anxiety, mood, and calmness as indicators of psychological stress response. For physiological stress reactivity, the areas under the curve with respect to the ground (AUC_G) were compared.ResultsIn all three exercise groups, experimentally induced stress led to a significant rise in heart rate, cortisol, and state anxiety; mood and calmness significantly decreased. As hypothesized, the pattern of the physiological stress response differed for the three exercise groups, with lowered reactivity in the more active groups. However, the psychological stress response partly went in the opposite direction: Exercising participants reported a higher mood decrease, suggesting a dissociation of the physiological and psychological stress responses.ConclusionsThe findings suggest that the Cross-Stressor Adaptation hypothesis is also valid for young women; however, only with regard to physiological stress response. The unexpected findings for psychological stress response need to be further explored in experimental studies.     

Interpersonal Conflicts of Women in Nursing Homes: An Administrative Perspective

Older women may respond to conflicts by suppressing anger. Suppressed anger is associated with depression and hypertension. Research on the everyday conflicts of community-dwelling older women has begun to emerge. Such information is not available for women in nursing homes, and is necessary for developing interventions that can help protect women in nursing homes against anger-related illness. Nursing home administrators were surveyed to evaluate women's health promotion programming in general, and the incidence of and institutional response to conflicts of women residents. About 74% of residents were women; yet, women's health promotion programs were rare (offered in 1 out of 25 facilities, or 4%). Ninety percent of administrators identified depression as the most significant women's health problem, but tended to see it as warranting medical rather than programmatic attention. Eighty percent identified strained interpersonal relationships as a significant health problem for women, requiring programmatic attention. In particular, administrators identified the need for programming to help women residents resolve conflicts with roommates and family members. Formal mechanisms for managing conflicts of residents did not exist in sample nursing homes.     

The Effect of Exercise on Body Satisfaction and Self-Esteem as a Function of Gender and Age

The study investigated the relationship between amount of exercise and psychological well-being in a broadly based sample. A questionnaire assessing amount of exercise, reasons for exercise, body satisfaction, and self-esteem was completed by 252 participants between the ages of 16 and 60 years. Almost all participants (>95%) were White. Participants were divided into four groups on the basis of gender and age, resulting in 70 young women, 48 young men, 73 mature women, and 61 mature men. Significant negative relationships between amount of exercise and body satisfaction and self-esteem were found for young women, and positive relationships for the remainder of the sample. Women exercised more for reasons of weight control, tone, and mood enhancement than men. For the whole sample, the first two of these reasons were associated with lower body satisfaction, while exercising for health and fitness reasons was associated with increased self-esteem. It was concluded that reasons for exercising did not provide an adequate explanation for the obtained difference in correlations across gender and age.     

ON THE NEED FOR QUALITY CONTROL IN VALIDATION RESEARCH

The aptitude tests used to help make personnel decisions about military recruits were validated against hands-on tests of job performance in two Marine Corps occupational specialties, radio repairers and automotive mechanics. The tests were administered by Marine Corps noncommissioned officers. Marine Corps units provided the test administrators, testing facilities, and examinees. Data collected under such conditions are filled with errors that reduce the accuracy of validity coefficients. This paper shows how validity coefficients can be made more accurate by exercising quality control during the statistical analysis.     

Friendship Selection and Influence Processes for Physical Aggression and Prosociality: Differences between Single-Sex and Mixed-Sex Contexts

The present study examined to what extent selection and influence processes for physical aggression and prosociality in friendship networks differed between sex-specific contexts (i.e., all-male, all-female, and mixed-sex classrooms), while controlling for perceived popularity. Whereas selection processes reflect how behaviors shape friendships, influence processes reveal the reversed pattern by indicating how friends affect individual behaviors. Data were derived from a longitudinal sample of early adolescents from Chile. Four all-male classrooms (n = 150 male adolescents), four all-female classrooms (n = 190 female adolescents), and eight mixed-sex classrooms (n = 272 students) were followed one year from grades 5 to 6 (M _age = 13). Analyses were conducted by means of stochastic-actor-based modeling as implemented in RSIENA. Although it was expected that selection and influence effects for physical aggression and prosociality would vary by context, these effects showed remarkably similar trends across all-male, all-female, and mixed-sex classrooms, with physical aggression reducing and with prosociality increasing the number of nominations received as best friend in all-male and particularly all-female classrooms. Further, perceived popularity increased the number of friendship nominations received in all contexts. Influence processes were only found for perceived popularity, but not for physical aggression and prosociality in any of the three contexts. Together, these findings highlight the importance of both behaviors for friendship selection independent of sex-specific contexts, attenuating the implications of these gendered behaviors for peer relations.     

The frequency, nature, and effects of naturally occurring appearance-focused social comparisons

This research examined the effects of naturally occurring appearance-focused social comparisons on women's affect, body satisfaction, and weight-related cognitions. During their daily activities, women reporting body dissatisfaction (n=53) and women reporting body satisfaction (n=34) recorded their reactions to comparison information. Body-dissatisfied women engaged in more comparisons and a greater proportion of upward comparisons than body-satisfied women. Upward comparisons were associated with an increase in negative affect, body dissatisfaction, and thoughts of exercising for both groups; however, body-dissatisfied women experienced a greater increase in thoughts of dieting following upward comparisons. The daily effects of comparison information on body-dissatisfied women were examined; upward comparisons were associated with increases in daily negative affect, body dissatisfaction, and weight-related cognitions.     

Does Reducing Male Domination in Teams Attenuate or Intensify the Harmful Effects of Perceived Discrimination on Women's Job Satisfaction? A Test of Competing Hypotheses

This study tested competing theoretical predictions surrounding the moderating effect of male domination in teams on the relation between women's perceptions of gender discrimination and their job satisfaction. Using archival data from an all-female sample of active military personnel (n = 3,015) comprising 321 work teams, which fell on a continuum from less male dominated to more male dominated, we found that the extent to which teams were male dominated moderated the negative link between perceived gender discrimination and job satisfaction, such that perceptions of discrimination were more negatively related to job satisfaction for women working in teams that were less male dominated than for those working in teams that were more male-dominated. We conclude by discussing the implications of our findings for research and practice and highlight several avenues for future research.     

Building blocks of bias: Gender composition predicts male and female group members’ evaluations of each other and the group

The present research examined how a group's gender composition influences intragroup evaluations. Group members evaluated fellow group members and the group as a whole following a shared task. As predicted, no performance differences were found as a function of gender composition, but judgments of individuals’ task contributions, the group's effectiveness, and desire to work with one's group again measured at a 10-week follow-up were increasingly negative as the proportion of women in the group increased. Negative judgments were consistently directed at male and female group members as indicated by no gender of target effects, demonstrating that men, simply by working alongside women, can be detrimentally affected by negative stereotypes about women. Implications for gender diversity in the workplace are discussed.     

Differences in male and female patterns of communication in groups: A methodological artifact?

This study investigated communication patterns in an all-male, all-female, and mixed-sex group. All participants were white and middle class. These groups met for longer periods of time than those in most previous studies that reported differences between men and women in task and maintenance communication patterns. Most previous research investigations were based on groups that met for an hour or less and used unacquainted undergraduates. In this study, no significant differences were found in seven categories of verbal input. While there were no significant differences, the typical pattern reported in the literature was present in the first 30–60 minutes of the groups. After that time period, no consistent patterns were noted, and stereotypic sex differences vanished. This has led the authors to tentatively conclude that the findings of previous research may be due to the limited time period used in most investigations. Men and women did not differ on task and maintenance input, or other categories of verbal input, in groups meeting for 4 1/2 hours or 6 hours.
