Previous research has shown that HIV stigma in India can be characterized by a framework dividing manifestations into enacted (discrimination), vicarious (hearing stories of discrimination), felt normative (perceptions of stigma's prevalence), and internalized stigma (personal endorsement of stigma beliefs). We examined whether this framework could explain associations among stigma, efforts to avoid HIV serostatus disclosure, and depression symptoms in a cohort of 198 HIV-infected individuals from Southern India who were followed up for one year as part of a study of antiretroviral adherence. Prior studies had suggested that disclosure avoidance was a primary outcome of stigma and that impaired well-being was a primary outcome of disclosure avoidance. Analyses from our longitudinal research revealed that the pattern of associations among stigma, disclosure avoidance, and depression symptoms remained consistent over time. Enacted and vicarious stigmas were correlated with felt normative stigma beliefs. In turn, felt normative stigma was correlated with disclosure avoidance. And, enacted stigma, internalized stigma, and disclosure avoidance were all associated with depression symptoms. However, even though the overall framework held together, internalized stigma and depression symptoms dropped significantly over time while other components remained unchanged. These findings suggest that, although HIV stigma may limit disclosure, it does not invariably lead to psychological maladjustment. Amidst ongoing perceptions and experiences of stigma, HIV-positive individuals can achieve significant improvements in their acceptance of the disease and in mental well-being.  相似文献

The value of symptom validity tests in a forensic context is currently the subject of a controversial debate in Germany. The discussion primarily focuses on neuropsychological symptom validity tests, however, tests specific for mental disorders are neglected. Unfortunately, no assessment tools for symptom validation of mental disorders of German origin are available and adaptations of available English state of the art instruments have not yet been tested. Further research of assessment development and qualitative analysis of the decision-making process in medicolegal evaluation is needed in German speaking countries.  相似文献

The present work aims to investigate the relation between appraisals, emotions, and emotion regulation strategies by creating a structural equation model which integrates these three aspects of the emotion process. To reach this aim, Italian students (N = 610) confronted with their high school diploma examination completed a questionnaire 3 weeks before the beginning of the exam. Results showed that they experienced primarily three types of emotions—anxiety/fear, frustration/powerlessness, positive emotions—which were related to specific appraisal profiles. Importantly, these appraisal profiles and emotions were associated with the use of different strategies for regulating emotions: anxiety/fear was associated with focusing on the exam, drug use, and an inability to distance oneself from the exam; frustration/powerlessness, with use of suppression, distancing, and drugs; positive emotion, with reappraisal and problem focused strategies. The effectiveness of these different strategies will be discussed.  相似文献

Novice drivers (teen drivers with their solo license for 6 months or less) are at a greatly inflated risk of crashing. Post hoc analyses of police accident reports indicate that novice drivers fail to anticipate hazards, manage their speed, and maintain attention. These skills are much too broadly defined to be of much help in training. Recently, however, driving simulators have been used to identify those skills which differentiate the novice drivers from older, more experienced drivers in the areas of hazard anticipation and speed management. Below, we report an experiment on a driving simulator which compares novice and experienced drivers’ performance in the third area believed to contribute especially heavily to crashes among novice drivers: attention to the forward roadway. The results indicate that novice drivers are much more willing to glance for long periods of time inside the vehicle than are experienced drivers. Interestingly, the results also indicate that both novice and experienced drivers spend equal amounts of time glancing at tasks external to the vehicle and in the periphery. Moreover, just as a program has been designed to train the scanning skills that clearly differentiate novice from experienced drivers, one might hope that a training program could be designed to improve the attention maintenance skills of novice drivers. We report on the initial piloting of just such a training program. Finally, we address a question that has long been debated in the literature: Do the results from driving simulators generalize to the real world? We argue that in the case of hazard anticipation, speed management, and attention maintenance the answer is yes.  相似文献

The present study investigated how European adolescents cope with perceived future-related stress. Altogether 3,154 adolescents (mean age of 15 years) from four countries (n = 1,071 Italians, n = 1,433 Germans, n = 308 French, and n = 341 British) participated in the study. They completed the Problem Questionnaire, which assesses future-related stress, and the CASQ, which assesses how three coping styles (active coping, internal coping, and withdrawal) are used to deal with future-related stress. German and British adolescents showed low levels of stress, whereas French and Italian adolescents had high levels. All adolescents anticipated future-related problems but did not portray their futures negatively. In addition, they dealt with future-related stress actively and showed high levels of coping competence. Adolescents used active coping strategies most frequently, followed by thinking about possible solutions. Dysfunctional coping strategies (e.g., withdrawal) were used much less often. The effects of age, gender, and family variables on stress perception and coping style were negligible. Overall, our findings highlight the tenets of positive psychology by revealing that adolescents are concerned about their futures and that they show high agency in dealing with future-related problems. Further, the findings are relevant for positive youth development programs, especially those which endorse positive orientation to the future and coping competence.  相似文献

We demonstrate qualitative dissociations of brightness processing in visuomotor priming and conscious vision. Speeded keypress responses to the brighter of two luminance targets were performed in the presence of preceding dark and bright primes (clearly visible and flanking the targets) whose apparent brightness values were enhanced or attenuated by a visual illusion. Response times to the targets were greatly affected by consistent versus inconsistent arrangements of the primes, relative to the targets (response priming). Priming effects could systematically contradict subjective brightness matches, such that one prime could appear brighter than the other but could prime as if it were darker. Systematic variation of the illusion showed that response-priming effects depended only on local flanker-background contrast, not on the subjective appearance of the flankers. Our findings suggest that speeded motor responses, as opposed to conscious perceptual judgments, access an early phase of lightness and brightness processing prior to full lightness constancy.  相似文献

Previous evidence suggests that attention can operate on object-based representations. It is not known whether these representations encode depth information and whether object depth, if encoded, is in viewer- or objectcentered coordinates. To examine these questions, we employed a spatial cuing paradigm in which one corner of a 3-D object was exogenously cued with 75% validity. By rotating the object in depth, we can determine whether validity effects are modulated by 2-D or 3-D cue-target distance and whether validity effects depend on the position of the viewer relative to the object. When the image of a 3-D object was present (Experiments 1A and 1B), validity effects were not modulated by changes in 2-D cue-target distance, and shifting attention toward the viewer led to smaller validity effects than did shifting attention away from the viewer. When there was no object in the display (Experiments 2A and 2B), validity effects increased linearly as a function of 2-D cue-target distance. These results demonstrate that attention spreads across representations of perceived objects that encode depth information and that the object’s orientation in depth is encoded in viewer-centered coordinates.  相似文献

The term “joint attention”, which first gained currency in the early 1960s in studies of the development of language and symbolic thought, remains significant in the developmental literature. However, its meaning is unclear. A definitional problem exists similar to what Patterson [Patterson, M. L. (1982). A sequential functional model of nonverbal exchange. Psychological Review, 89, 231–249] described as the “dual usage” problem in the study of behaviour. The dual usage problem manifests when the behaviours of interest are used interchangeably with the function served by those behaviours. Similarly, the behaviours or skills that are taken to show joint attention are used interchangeably with the functions served by these behaviours. Scant attention is given to how the behaviours are generated and regulated and how they contribute to development. The purpose of the present position paper was: (1) to identify and illustrate the ways in which the behaviours and functions of joint attention have been confounded in the literature; (2) to provide a revised operationalization of joint attention incorporating the idea of Consummative Joint Attention, which is defined as a process variable that integrates these two theoretically different and complementary aspects of “joint attention;” and (3) to test this revised definition with evidence from a sample of hearing mothers and their 18- to 36-month-old hearing or deaf toddlers. We suggest that a reconceptualization and revised definition of joint attention as a process served by a particular sequence of complementary and well-timed events in the behaviour of mother–child interaction are particularly well-suited to testing joint attention as an early prelingual mechanism and to detecting early problems with psychosocial and adaptive development created by ineffective patterns of social interaction.  相似文献

In this study, the longitudinal relation between deliberate practice and performance in chess was examined using a linear mixed models analysis. The practice activities and performance ratings of young elite chess players, who were either in, or had dropped out of the Dutch national chess training, were analysed since they had started playing chess seriously. The results revealed that deliberate practice (i.e. serious chess study alone and serious chess play) strongly contributed to chess performance. The influence of deliberate practice was not only observable in current performance, but also over chess players' careers. Moreover, although the drop‐outs' chess ratings developed more slowly over time, both the persistent and drop‐out chess players benefited to the same extent from investments in deliberate practice. Finally, the effect of gender on chess performance proved to be much smaller than the effect of deliberate practice. This study provides longitudinal support for the monotonic benefits assumption of deliberate practice, by showing that over chess players' careers, deliberate practice has a significant effect on performance, and to the same extent for chess players of different ultimate performance levels. The results of this study are not in line with critique raised against the deliberate practice theory that the factors deliberate practice and talent could be confounded.  相似文献
