The current study aimed to understand how sex differences in the timing of hypertension onset contribute to early midlife risk for cognitive decline that may differ by sex and whether sex-dependent advantages in normotensive populations are influenced by the presence of hypertension. One hundred and ninety-five adults aged 45–55 from the New England Family Study underwent neuropsychological testing to assess attention, executive function, and memory. Physician-diagnosed hypertension status was self-reported via questionnaire. Mid-adulthood hypertension was associated with worse performance on measures of attention and memory, but the cognitive domains impacted varied by sex. Hypertension was associated with only attention in men, whereas in women it was associated with attention and associative and working memory. Sex differences in midlife cognitive performance found in normotensive adults were attenuated in those with hypertension. Our results underscore the importance of accounting for sex when assessing the impact of hypertension on midlife cognition that could be indicative of later decline and risk for cognitive impairment and dementia, given hypertension is an independent risk factor.  相似文献

A meta-analysis of 45 studies of transformational, transactional, and laissez-faire leadership styles found that female leaders were more transformational than male leaders and also engaged in more of the contingent reward behaviors that are a component of transactional leadership. Male leaders were generally more likely to manifest the other aspects of transactional leadership (active and passive management by exception) and laissez-faire leadership. Although these differences between male and female leaders were small, the implications of these findings are encouraging for female leadership because other research has established that all of the aspects of leadership style on which women exceeded men relate positively to leaders' effectiveness whereas all of the aspects on which men exceeded women have negative or null relations to effectiveness.  相似文献

This study tested the oblique four-factor model of the Gender Role Conflict Scale for a sample of gay men and lesbian women residing in the United States. 400 gay men and 292 lesbian women recruited from university and college gay, lesbian, bisexual, and transgender LISTSERVs participated. The internal consistency reliability of the Gender Role Conflict Scale scores was high, but low means on the expressive dimension of gender role conflict were noted. The results of two separate sets of confirmatory factor analyses indicated that the four-factor model's fit to the data could be enhanced for both groups by applying item parceling to lower the number of indicators per factor, suggesting that the actual structural validity of the Gender Role Conflict Scale may be better than suggested by the reported fit indices.  相似文献

In this article, a leadership model is presented, with which to investigate the relationship of trait emotional intelligence (trait EI), leadership self-efficacy and leader's task self-efficacy with collective task efficacy and group performance. The sample was made up of 217 undergraduate students, randomly assigned to work teams of 1 leader and 2 followers that were requested to perform a production task. An adapted version of the Schutte Self-Report Inventory (SSRI; Schutte et al., 1998) was used to measure trait EI. Structural equation modeling was used to test the hypothesized relationships. Results indicated that task self-efficacy was a mediator between leadership self-efficacy and collective task efficacy; the latter, in turn, was the best predictor of group performance. No significant relationship was found between trait EI and collective task efficacy although, unexpectedly, trait EI was positively associated with leadership self-efficacy. Implications of the results are discussed.  相似文献

Although gender bias is clearly evident in the provision of institutional social support, it is unclear whether such bias exists on a more subtle and interpersonal level. When women act appropriately assertive at work, they may actually alienate support. This paper reports an experimental study that addressed this general issue of social support among employed men and women. A sample of 61 males and 55 females (predominantly white; N=116), employed by four northeast Ohio employers participated. The extent of preference to offer support to assertive males and females was explored. An unexpected double bias was found, with each sex preferring to offer support to their own sex.This project was funded by a grant received by the Applied Psychology Center of Kent State University, from the Ohio Department of Development through the Northeast Ohio Center for the Advancement of Labor Management Cooperation.

This study examined the effects of gender-role orientation on aspects of body image satisfaction in a group of primarily Caucasian young women and men. It also examined whether neuroticism—a broad, higher-order dimension of personality—functioned additively or interactively with gender-role orientation in the prediction of body image. Similar to previous research, masculinity was related to positive body image in women. For men, results were in the opposite direction. Femininity, and not masculinity, was related to body satisfaction. Of particular interest were the findings that neuroticism interacted both with masculinity in women and femininity in men in predicting positive ratings of attractiveness. In both cases, the positive relationship between gender-role orientation and attractiveness only existed at low levels of neuroticism. As neuroticism increased, the relationship diminished; there was no relationship at all at high levels of neuroticism. Results are discussed in terms of the differential significance of gender-role orientation for body esteem in women and men, and with respect to the moderating influence of personality factors.  相似文献

Women leave science fields at greater rates than men, and loss of interest is a key motivator for leaving. Although research widely demonstrates effects of gender bias on other motivational processes, whether gender bias directly affects feelings of interest toward science activities is unknown. We used a false feedback paradigm to manipulate whether women (Study 1) and men (Study 2) participants perceived the reason for feedback as due to pro-male bias. Because activity interest also depends on how students approach and perform the activity, effects of biased feedback on interest appraisals were isolated by introducing gender bias only after the science activity was completed. When the feedback was perceived as due to pro-male bias, women (Study 1) reported lower interest and men (Study 2) reported greater interest in the science activity, and interest, in turn, positively predicted subsequent requests for career information in both studies. Implications for understanding diverging science interests between women and men are discussed.  相似文献

This is the third in a series of studies evaluating how transformational leadership is associated with related variables such as job satisfaction, change commitment, leadership trust, cooperative conflict management, and market orientation. The present paper evaluates the effects of transformational leadership and cooperative conflict management along with their mediating and moderating of leadership trust in the life insurance industry for two sample groups, sales managers and sales employees. The main effect of leadership trust was mediated and moderated by cooperative conflict management. Cooperative conflict management made a more important contribution than transformational leadership or the moderating effect (interaction), but these three together were the most important variables predicting highest leadership trust. Transformational leadership has an indirect influence on leadership trust. This work summarizes the specific contribution and importance of building successful leadership trust associations with employees in relation to leadership and satisfaction with change commitment.  相似文献

Academic conferences are important settings for socialization, scholarly engagement, and networking. Two studies explore the effects of ambient cues in such settings on women's and men's climate perceptions. Participants (undergraduates in Study 1, graduate students in Study 2) viewed a flyer advertising a professional mixer that included an eroticized image or a control image. Women and men expected a sexualized atmosphere, and women in particular anticipated lower feelings of competence and greater discomfort and objectification at the event advertised with the erotic image. The negative effect of erotic flyer exposure on competence was mediated by discomfort (Study 1) and objectification (Study 2), particularly in women. Results are interpreted in light of pipeline leakage and women's success in the Academy.  相似文献

Male and female subjects provided ratings of personal traits, femininity and masculinity, and total caloric consumption for a female or a male target based on the type of diet she or he had allegedly consumed. The gender associated with the foods presented for each dietary profile was manipulated. Results showed that Target Gender and Dietary Profile significantly affected impression ratings and calorie estimates. Both male and female subjects perceived male eaters and those who ate a feminine diet more favorably. Results are discussed in terms of the different underlying expectations held for males and females when food consumption is involved during the impression formation process.  相似文献

As women continue to enter and advance within management ranks, how gender and leadership style influence subordinate satisfaction remains a significant issue. This paper reports on an experiment that analyzed the effects of gender and leadership style on subordinate satisfaction. While subjects were more satisfied in democratically led groups, gender of leader did not significantly affect satisfaction. Female subordinates were more dissatisfied than males in autocratically led groups.  相似文献

The effects of maternal employment on young adults' gender role attitudes were assessed. A random sample of 111 males and 131 females was surveyed [179 Whites (74.0%), 35 Blacks (14.5%), and 28 others (typically Asian-Americans, 11.5%)]. Results varied depending on which gender role attitudes were being examined. With respect to approval of mother working outside the home, only the respondent's age when his or her mother began working was significant. However, this relationship was not found when assessing attitudes about the separate spheres ideology. Thus, it appears that attitudes toward women working depend on whether the respondent's mother worked, whereas beliefs about adult male—female equality do not appear to be as closely related to childhood experiences. Mothers' occupations were unrelated to all of the attitudes examined, as were her children's perceptions of how satisfied she was with her primary work role (employed or nonemployed). Finally, the only significant predictors of gender role attitudes to be discovered were the sex of respondent and attendance at religious services. Females expressed more egalitarian gender role attitudes, and those who reported frequent attendance at religious services were more likely to endorse traditional gender roles.This article was part of a master's thesis conducted at the University of Virginia by the first author.We gratefully acknowledge the assistance of Paul W.

Little research has considered how work team characteristics influence feedback-seeking behavior among team members. The authors' aim in this research was to identify central sources of influence on feedback-seeking behavior in a mixed-gender context. They placed men and women in work groups of varying gender composition. The participants then participated in a gender-biased (perceived as either male-oriented or female-oriented) negotiation exercise. Findings indicated that the gender of the participant, the team's gender composition, and the gender orientation of the task influenced feedback-seeking behavior among team members.  相似文献

Men often score higher than women do on traits or tendencies marked by hostile dominance. The purpose of the present research was to contribute to an understanding of these gender differences. Four studies (total N?=?494 U.S. undergraduates) administered a modified animal preference test in which participants could choose to be predator or prey animals, but not labeled as such. Men were consistently more interested in being predator animals than women were, displaying a sort of hostile dominance in their projective preferences. Predator self-identifications, in turn, mediated gender differences in outcomes related to hostile dominance. Studies 1 and 2 provided initial evidence for this model in the context of variations in interpersonal arrogance, and Studies 3 and 4 extended the model to nonverbal displays and daily life prosociality, respectively. The findings indicate that gender differences in hostile dominance are paralleled by gender differences in preferring to think about the self in predator-like terms. Accordingly, the findings provide new insights into aggressive forms of masculine behavior.  相似文献

Research has shown that men tend to emerge as leaders more frequently than women. However, societal role expectations for both women and leaders have changed in the decades since the last empirical review of the gender gap in leader emergence (Eagly & Karau, 1991). We leverage meta‐analytic evidence to demonstrate that the gender gap has decreased over time, but a contemporary gap remains. To understand why this gap in leader emergence occurs, we draw on social role theory to develop a Gender‐Agency/Communion‐Participation (GAP) Model—an integrative theoretical model that includes both trait and behavioral mechanisms. Specifically, we examine a sequence of effects: from gender to agentic and communal personality traits, from these traits to behavioral participation in group activities, and ultimately from participation to leader emergence. The model is tested using original meta‐analyses of the personality and behavioral mechanisms (coding 1,632 effect sizes total). Gender differences in leadership emergence are predominately explained by agentic traits (positive) and communal traits (negative), both directly and through the mechanism of participation in group discussions. In addition, several paths in the theoretical model are moderated by situational contingencies. Our study enhances knowledge of the mechanisms and boundary conditions underlying the gender gap in leader emergence.  相似文献

This study identified potential discontinuities in the antecedents of efficacy beliefs across levels of analysis, with a particular focus on the role of leadership climate at different organizational levels. Random coefficient modeling analyses conducted on data collected from 2,585 soldiers in 86 combat units confirmed that soldiers' experience, role clarity, and psychological strain predicted self-efficacy to a greater extent than did leadership climate. Also, leadership climate at a higher organizational level related to self-efficacy through role clarity, whereas leadership climate at a lower organizational level related to self-efficacy through psychological strain. Group-level analyses identified leadership climate at a higher organizational level as the strongest predictor of collective efficacy. Theoretical and practical implications and directions for future research are discussed.  相似文献

Gender differences in the neuroendocrine and cardiovascular response to psychological stress may contribute to the gender differences in the prevalence of diseases associated with hypothalamic-pituitary-adrenal (HPA) axis reactivity such as cardiovascular disease (CVD), diabetes and hypertension. We measured plasma ACTH, cortisol, heart rate (HR), and blood pressure (BP) responses in 8 men and 8 women (55-75 years) exposed to the Matt Stress Reactivity Protocol (MSRP), a psychological challenge. The MSRP elicited significant increases in HR, systolic-, and diastolic BP, ACTH and cortisol (all p<0.01). Men had significantly greater cortisol and diastolic BP responses compared to women (p<0.05). Additionally, a positive correlation between the ACTH and cortisol responses was only found in the males (r=0.71, p<0.05). There were no group differences in HR, systolic BP, or ACTH responses. We conclude, that among older adults, men respond to psychological stress with greater increases in cortisol, compared to women. This greater activation of the HPA axis could translate into an elevated risk for CVD, diabetes and hypertension and may be related to the higher prevalence of these diseases in males. Gender differences in brain structures and/or cognitive processes may be responsible for these sexually dimorphic stress responses.  相似文献

In order to test the social mechanisms through which organizational climate emerges, this article introduces a model that combines transformational leadership and social interaction as antecedents of climate strength (i.e., the degree of within-unit agreement about climate perceptions). Despite their longstanding status as primary variables, both antecedents have received limited empirical research. The sample consisted of 45 platoons of infantry soldiers from 5 different brigades, using safety climate as the exemplar. Results indicate a partially mediated model between transformational leadership and climate strength, with density of group communication network as the mediating variable. In addition, the results showed independent effects for group centralization of the communication and friendship networks, which exerted incremental effects on climate strength over transformational leadership. Whereas centralization of the communication network was found to be negatively related to climate strength, centralization of the friendship network was positively related to it. Theoretical and practical implications are discussed.  相似文献
