This study examines the motivational factors contributing to course selection in a sample of students enrolled in an intensive three-week academic experience for exceptionally talented adolescents. Our sample included 947 gifted adolescents, of whom 3.7% were Black, 73.5% were White, 2.2% Hispanic, 0.1% Native American, 19.8% Asian, and 0.6% categorized themselves as other. Girls and boys selected different types of classes, with course participation falling along traditional gender-stereotyped lines. Boys and girls both performed exceptionally well, and said they chose their course because the subject was interesting, useful for future goals, and challenging. Females more often than males enrolled in classes because they perceived them as challenging, different from usual, not offered at school, and as making them more well-rounded. Males more often than females tended to select classes because they thought they would do well and/or because they viewed these classes as being useful for future schooling or career. However, these gender differences varied by the type of course the students took. The resulting complex picture of students' motivations is discussed in terms of the need to specify both the contexts in which males and females make their academic choices, and the interactive determinants of their motivations.An earlier version of this paper was presented at the Third Annual Esther Katz Rosen Symposium on the Psychological Development of Gifted Children, University of Kansas, Lawrence, Kansas, February 19–20, 1993. 相似文献

Business students were asked to indicate their pay expectations and anticipated negotiation strategies for a specific management trainee job. They also indicated expectations for their and the recruiter's target and resistance points for the negotiation process. Men, compared to women, indicated higher pay expectations, a higher likelihood of active negotiation, less likelihood of using traditional self-promotion strategies, and more opportunity for legitimate negotiations. Significant correlations were found between pay expectations and negotiation strategies. Intervention strategies for changing women's pay outcome and negotiation expectations are discussed, as well as the need for a better understanding of effective negotiation behaviors.This research was supported by the Colorado State University College of Business Summer Research Grant Program. An abbreviated version of this article was presented at the 50th Annual meeting of the Academy of Management, Women in Management Division, August 13, 1990, San Francisco, California.We gratefully acknowledge the critical comments of Kevin R. Murphy, Jeanette N. Cleveland, and Russell Cropanzano on an earlier draft of this article. 相似文献

Across a range of decision contexts, we provide evidence of a novel proximity bias in probability judgments, whereby spatial distance and outcome valence systematically interact in determining probability judgments. Six hypothetical and incentive-compatible experiments (combined N = 4007) show that a positive outcome is estimated as more likely to occur when near than distant, whereas a negative outcome is estimated as less likely to occur when near than distant (studies 1–6). The proximity bias is explained by wishful thinking and thus perceptions of outcome desirability (study 3), and it does not manifest when an outcome is less relevant for the self, such as the case of outcomes with little consequence for the self (studies 4 and 5) or when estimating outcomes for others who are irrelevant to the self (study 6). Overall, the proximity bias we document deepens our understanding of the antecedents of probability judgments. 相似文献

Using rape myth research as a template, we developed a conceptual definition and measurement instrument for the mythology regarding male sexual harassment of women, resulting in the 20-item Illinois Sexual Harassment Myth Acceptance (ISHMA) Scale. Surveys from 337 students in the Midwestern region of the United States revealed that this measure consists of four factors, which share predicted relationships with rape mythology, sexism, hostility toward women, traditional attitudes toward women, and ideological support for the feminist movement. We also found that women and individuals with prior training on sexual harassment reject these myths more than men and untrained individuals. It is hoped that this new definition, conceptualization, and measure will advance knowledge on attitudes that support and perpetuate violence against women. 相似文献

The NO-cGMP-PKG signaling pathway regulates synaptic plasticity and fear memory consolidation in the lateral amygdala via activation of ERK/MAP kinase 下载免费PDF全文

Recent studies have shown that nitric oxide (NO) signaling plays a crucial role in memory consolidation of Pavlovian fear conditioning and in synaptic plasticity in the lateral amygdala (LA). In the present experiments, we examined the role of the cGMP-dependent protein kinase (PKG), a downstream effector of NO, in fear memory consolidation and long-term potentiation (LTP) at thalamic and cortical input pathways to the LA. In behavioral experiments, rats given intra-LA infusions of either the PKG inhibitor Rp-8-Br-PET-cGMPS or the PKG activator 8-Br-cGMP exhibited dose-dependent impairments or enhancements of fear memory consolidation, respectively. In slice electrophysiology experiments, bath application of Rp-8-Br-PET-cGMPS or the guanylyl cyclase inhibitor LY83583 impaired LTP at thalamic, but not cortical inputs to the LA, while bath application of 8-Br-cGMP or the guanylyl cyclase activator YC-1 resulted in enhanced LTP at thalamic inputs to the LA. Interestingly, YC-1-induced enhancement of LTP in the LA was reversed by concurrent application of the MEK inhibitor U0126, suggesting that the NO-cGMP-PKG signaling pathway may promote synaptic plasticity and fear memory formation in the LA, in part by activating the ERK/MAPK signaling cascade. As a test of this hypothesis, we next showed that rats given intra-LA infusion of the PKG inhibitor Rp-8-Br-PET-cGMPS or the PKG activator 8-Br-cGMP exhibit impaired or enhanced activation, respectively, of ERK/MAPK in the LA after fear conditioning. Collectively, our findings suggest that an NO-cGMP-PKG-dependent form of synaptic plasticity at thalamic input synapses to the LA may underlie memory consolidation of Pavlovian fear conditioning, in part, via activation of the ERK/MAPK signaling cascade. 相似文献

Individuals with Williams syndrome (WS) and autism are characterized by different social phenotypes but have been said to show similar atypicalities of face‐processing style. Although the structural encoding of faces may be similarly atypical in these two developmental disorders, there are clear differences in overall face skills. The inclusion of both populations in the same study can address how the profile of face skills varies across disorders. The current paper explored the processing of identity, eye‐gaze, lip‐reading, and expressions of emotion using the same participants across face domains. The tasks had previously been used to make claims of a modular structure to face perception in typical development. Participants with WS (N=15) and autism (N=20) could be dissociated from each other, and from individuals with general developmental delay, in the domains of eye‐gaze and expression processing. Individuals with WS were stronger at these skills than individuals with autism. Even if the structural encoding of faces appears similarly atypical in these groups, the overall profile of face skills, as well as the underlying architecture of face perception, varies greatly. The research provides insights into typical and atypical models of face perception in WS and autism. 相似文献

The authors examined whether 3 individual difference variables--self-esteem, self-efficacy, and depressive symptoms--interacted with psychoeducational group interventions for men with prostate cancer (n = 250) to predict general and prostate-specific quality of life. Men with nonmetastatic prostate cancer were randomly assigned to an education intervention, an education plus group discussion intervention, or usual care and followed for 12 months. Eight groups of 10 to 12 men were convened in each condition. Men who began the study with lower self-esteem, lower prostate-specific self-efficacy, and higher depressive symptoms benefited the most from the interventions. Of these 3 moderator variables, the most consistent results emerged for self-esteem. That is, the benefits of the intervention were strongest for men with low self-esteem. 相似文献

This study explored how children's sustained attention develops and the effect of manipulating task parameters on sustained attention. The sample comprised 57 children (5-12 years) who completed CogState and Score! (Test of Everyday Attention for Children). Novel variability and traditional indices indicated rapid development from 5-6 to 8-9 years on all measures and a developmental plateau from 8-9 to 11-12, with growth evident on some measures. Findings suggest that sustained attention improves to age 10, then plateaus with only minor improvements. Further, performance was generally poorer on high load tasks compared to low load, with the same developmental pattern uncovered. 相似文献

Memory for future actions, or prospective memory (PM), often involves remembering to do things for others. The present article explores the motivational mechanisms underlying memory for pro-social intentions through the manipulation of the social relevance of goals and presence of material rewards during an activity-based PM task. Results revealed that memory for the intention was better under pro-social than under standard conditions. However, when a material reward was introduced under pro-social conditions, it had the detrimental effect of reducing prospective remembering. Ongoing task performance was faster under pro-social than under No PM and standard PM conditions and it was unrelated to PM performance. In addition, the outcome of the ratings of two independent groups of participants confirmed that people are not aware of the potential conflict between pro-social and self-gain motives. Taken together, these new findings extend current PM theories by suggesting a prominent role of latent motivational mechanisms in guiding memory for pro-social intentions. 相似文献
