In rodents stress impairs delay as well as trace eyelid conditioning in females, but enhances it in males. The present study tested the effects of acute psychosocial stress exposure on classical delay eyeblink conditioning in healthy men and women. In a between subject design, participants were exposed to psychosocial stress using the Trier Social Stress Test (TSST) or a control condition which was followed by a delay eyeblink classical conditioning procedure. Stress exposure led to a significant increase in salivary cortisol and impaired acquisition of conditioned eyeblink responses (CRs). This was evident by a later first CR and an overall lower CR rate of the stress group. The stress-induced acquisition impairment was observed in both women and men. Subjects failing to show a stress-induced cortisol increase (cortisol non-responder) were not impaired in acquisition. Our findings indicate that acute stress, possibly via activation of the hypothalamus–pituitary–adrenal (HPA) axis, reduces the ability to acquire a simple conditioned motor response in humans. 相似文献

Traditionally, sexuality has not been a focus in couples therapy training, research, or practice, although it is an important, often complex issue for many couples. This article tells the story of a couple presenting for sex therapy due to their unconsummated marriage, and is told to exemplify how sex therapy and couples therapy can be integrated in order to best meet the needs of couples. As the story unfolds, the multilayered facets of the presenting issue are revealed. The therapy incorporates and weaves together family of origin history, intrapsychic and cognitive issues, relational dynamics, patterns of interaction, and physiological/medical concerns into a postmodern couples therapy with behavioral interventions. This combined approach recognizes the value of each method on its own and their greater usefulness when blended together. 相似文献

The purpose of this study was to investigate sex differences in psychological effects of exercise on university students. University students (73 female and 65 male) were randomly assigned to experimental and control groups by equating sex in each group. The experimental group participated in step dance sessions of 50 min per day, 3 days per week for 10 weeks with 60-80% of their heart rate reserves. Throughout the 10-week period, the lecture control group was told not to participate in any organized or structured exercise and participated in a lecture that was about the physiological and psychological benefits of exercise. Self-concept, belief in external control, and trait anxiety of the groups were measured before and after the exercise program. A significant improvement in the psychological variables after the exercise program and more improvement for female exercise participants were expected. Analysis revealed no significant initial differences in self-concept, belief in external control, and trait anxiety between the two groups or between males and females, other than family and moral/ethical self. Repeated measures analysis of variance revealed that exercise led to less belief in external control and significant improvement in physical self and identity dimensions of self-concept for the experimental group compared to the control group. However, there was no significant difference in trait anxiety between the two groups after exercise (p>.05). Analysis also revealed that changes in belief in external control, trait anxiety, and self-concept did not differ with regard to sex. Males and females showed no difference in their improvement on trait anxiety, belief in external control, and most dimensions of self-concept during the 10 weeks. Only changes in personal and physical self throughout 10-week period were different for males and females. Exerciser males improved their personal self and physical self scores more than female exercisers and male and female nonexercisers throughout the 10-week period (p<.05). 相似文献

Previous research has proposed that the ability to see others would benefit negotiations. We argue that this view is too narrow and that the impact of visual contact on negotiated agreements depends on the meaning individuals ascribe to either its presence or absence. Based on previous research showing that females are more likely to understand others in the presence of visual contact while males understand others better in the absence of visual contact, we explore how visual contact, eye contact, and sex affect the quality of negotiated agreements in a meta-analysis (Study 1) and a laboratory experiment (Study 2). The two studies combined show that because direct communication via the face facilitates a shared understanding for two unacquainted females, their agreements are of higher quality when they have visual contact compared to when they do not (Study 1), and if they have visual contact, their agreements are better when they have eye contact than when they do not (Study 2). Because communication via the face increases discomfort between two unacquainted males, their agreements are of higher quality when they do not have visual contact (Study 1), and if they do have visual contact, their agreements are better when they have no eye contact than when they do (Study 2). 相似文献

This study provides an experimental test of the hypothesis that level of gender constancy understanding affects children’s sex typing. Preschool-age children (N = 62, mean age = 47 months) were randomly assigned to experimental lessons that taught that biological traits (including gender) are either fixed (pro-constancy condition) or mutable (anti-constancy condition). Posttests revealed that the lessons were effective; children in the pro-constancy condition showed higher gender constancy and appearance–reality distinction scores than did children in the anti-constancy condition. Sex typing did not, however, differ between treatment conditions at immediate and 3-month posttesting. 相似文献

Based on the multiple goal perspective it is argued that mastery and performance goals contribute to different motivational variables-mastery goals to self-efficacy and performance goals to social comparison-that contribute through affect to achievement. The first aim of this study was to determine whether this model is applicable irrespective of sex and subject. The expected relationships occurred for female students studying Dutch and mathematics, and for male students studying Dutch. The second aim was to test a model in which the perceived gender appropriateness of the subject affects the pursued achievement goal. We expected that subjects perceived as gender-appropriate--Dutch for female and mathematics for male students--would result in strong relationships between mastery goals, self-efficacy, affect, and achievement, and that less gender-appropriate subjects--mathematics for women and Dutch for men--would result in strong relationships between performance goals, social comparison, affect, and achievement. Several of the expected relationships occurred for female and males students studying Dutch and mathematics. Furthermore, female students obtained higher course grades in Dutch than male students, while male students studying mathematics scored higher on self-efficacy and affect than female students. 相似文献

In Experiments 1 and 2, rats were trained in a Morris pool to find a hidden platform located some distance away from a single landmark. Males learned to swim to the platform faster than females, but on test trials without the platform, males, unlike females, spent less time in the platform quadrant of the pool in the second half of each test trial than in the first. They also showed greater persistence in searching in the platform quadrant over a series of extinction trials. In Experiments 3a and 3b, the problem was made easier by locating the platform closer to the solitary landmark. Now males and females learned to swim to the platform equally rapidly, and both stopped searching in the platform quadrant in the second half of each test trial. Experiment 4 ruled out the possibility that males´ shorter latencies to find the platform in Experiment 2 were due to their swimming faster than females. 相似文献

Since the reign of King Mohammed VI in 1999, there has been a recent democratic trend in Morocco that has led to political
liberalization and symbolic concessions. This essay explores how a new generation of artists is beginning to test the notions
of the Islam, the monarch, and the rights of ethnic groups and women within Morocco. I argue that while they are beginning
to test the limits of recent religious, social, and political reforms, these artists show self-restrain and selfcensorship,
creating art that falls within the public discourse allowed by the new Moroccan king.
