Background and Objectives: Research increasingly demonstrates that trauma exposure can have cumulative effects, yet much remains to be learned about effects of cumulative trauma, particularly regarding longer term adjustment. One such trauma, combat exposure, is insufficiently understood, especially for women, who are increasingly engaged in professional combat activities. Design: The study comprised a cross-sectional survey assessing multiple aspects of current well-being in women approximately 25 years after their service in Vietnam during the Vietnam War. Methods: Participants were 1374 women (78% military and 22% nonmilitary; mean age = 59.7). This study investigated the relations between three separate categories of trauma exposure (childhood, adulthood, and combat) and well-being and examined whether perceived social support at return from Vietnam moderated the association between combat exposure and well-being. Results: While both childhood and adulthood trauma exposure related to midlife well-being, combat exposure still uniquely predicted outcomes. Further, postdeployment perceived social support moderated the association of combat and well-being: recollected higher perceived social support at homecoming buffered participants from the links between combat exposure and well-being. Conclusions: These results may have important implications for interventions to reduce the impact of traumatic experiences, particularly in light of the increasing exposure of women to direct combat events.  相似文献

In 2 experiments, the authors manipulated the frequency of concurrent feedback to discern the effects on learning. In each experiment, participants (N = 48, Experiment 1; N = 36, Experiment 2) attempted to reproduce a criterion force-production waveform (5 s in duration) presented on the computer monitor. Consistent with the guidance hypothesis, the results of Experiment 1 indicated very strong guiding effects of concurrent feedback and strong dependence on the feedback, as indicated by participants' extremely poor performance upon feedback withdrawal in retention. As predicted by the guidance hypothesis, dependence on the feedback was reduced as a result of reducing the frequency of the concurrent feedback. The results of Experiment 2 indicated that one can enhance learning by providing concurrent and terminal feedback on 1 trial, with no feedback on the subsequent trial. In that way, the strong guiding effects of concurrent feedback could be realized and the beneficial effects of terminal feedback could also be achieved.  相似文献

The authors' primary purpose in the present experiment was to determine if practice changes the extent to which simple motor sequences are effector independent. Contralateral and ipsilateral effector transfers were assessed in 24 participants after 1 (200 trials) and 4 (800 trials) days of practice. The response sequence became increasingly effector dependent; the response structure and the scaling of force on the effector transfer tests were no better after 4 days of practice than after only 1 day, even though retention performance improved substantially. Those results are consistent with the notion that participants refine their movements over extended practice by exploiting the unique characteristics of the effectors. The additional practice results in a more effective movement when the same effectors are used but is of little value when different effectors are required.  相似文献

Little information is available about HF patients’ desires regarding having their healthcare providers address their spiritual concerns, feeling constrained in doing so, and the extent to which their spiritual needs go unmet. Nearly half of our sample reported high levels of unmet spiritual needs and reported moderately strong desires to have their doctor or other healthcare professional attend to their spiritual needs, and moderately strong feelings of constraint in doing so. Spiritual constraint and unmet spiritual needs were associated with poorer spiritual, psychological and physical well-being, but these effects varied, depending on patients’ desire to discuss spiritual needs. These findings have important implications for clinical management of HF patients.  相似文献

Generic statements about the abilities of children's social groups (e.g. ‘Girls/Boys are good at this game’) negatively impact children's performance – even if the statements are favorable towards children's own social groups. We explored the mechanism by which generic language impairs children's performance. Across three studies, our findings suggest that generic statements influence children's performance by creating an entity belief (i.e. a belief that a fixed ability determines performance). Children who were exposed to a generic statement about their social group's ability performed worse than children in control conditions. This effect hurt children's performance even when the person who made the generic statement was no longer present and a new person not privy to the statement replaced them. However, when children heard a generic statement paired with an effort explanation (i.e. ‘Girls/Boys are good at this game because they try really hard when they draw’) they performed better than children who heard the generic statement with no explanation (i.e. just ‘Girls/Boys are good at this game’) and children who heard the generic statement paired with a trait explanation (i.e. ‘Girls/Boys are good at this game because they are smart and really good at drawing’). This work uncovers when and how generic statements that refer to the ability of one's social group hinder performance, informing the development of practices to improve student motivation and learning.  相似文献

In this study based on an actual event, we examined how group members cognitively, affectively, and behaviorally respond to devaluation of ingroup’s social status. Integrating predictions from Social Identity Theory (SIT; Tajfel and Turner 1986) and Intergroup Emotions Theory (IET; Smith et al. Journal of Personality and Social Psychology, 93(3), 431–446 (2007)), we explored how appraisals about ingroup’s perceived decrease in status (i.e., stability and legitimacy of status change and permeability of group boundaries) are associated with discrete group-level emotions (e.g., anger, shame), and how those emotions in turn predict different coping strategies Blanz et al. European Journal of Social Psychology, 28(5), 697–729 (1998). Analyses of the results showed that: First, preference for each coping strategy varied according to appraisals of ingroup status, and the patterns were largely consistent with what SIT predicts. Second, different group-level emotions were reported according to appraisals of ingroup status. Third, inclusion of group-level emotions as mediators of associations between ingroup status appraisals and coping strategies significantly increased the explanatory power of the path models. In sum, this study demonstrated how the two theories on intergroup relations can be used together to offer a more detailed account of group identity management. For future direction, experimental or longitudinal designs as well as cross-cultural comparisons were suggested.  相似文献

Psychology and the U.S. military have a long history of collaboration. The U.S. Army Comprehensive Soldier Fitness (CSF) program aims to measure the psychosocial strengths and assets of soldiers as well as their problems, to identify those in need of basic training in a given domain as well as those who would benefit from advanced training, and then to provide that training. The goals of the CSF program include the promotion of well-being as well as the prevention of problems. Assessment is the linchpin of the CSF program, and the Global Assessment Tool (GAT) is a self-report survey that measures psychosocial fitness in emotional, social, family, and spiritual domains. We review the history of psychological assessment in the military and the lessons taught by this history. Then we describe the process by which the GAT was developed and evaluated. We conclude with a discussion of pending next steps in the development and use of the GAT.  相似文献

The purpose of this article is to examine the influence of retailer image on consumers' attitude towards private brand. More specifically, we evaluate two alternative perspectives of retailer image—the halo effect and the summary construct—and include a moderator variable, consumer familiarity with a retailer's private label products, to discern which of the two models has better explanatory power. The findings indicate that there are moderating effects of consumer familiarity with a retailer's private brands and product categories in determining the efficacy of each model. In private brand foods, high familiarity is related to the summary construct model, and low familiarity is associated with the halo effect model. In private brand clothing, however, low familiarity is related to the halo effect model, but high familiarity is associated with both the halo effect and the summary construct model. Managerial and future research implications are also provided.  相似文献
