Research indicates that when confronted with a health threat, individuals high in both dispositional and comparative optimism employ a more avoidant style of coping than individuals high in dispositional but low in comparative optimism. We examined the hypothesis that threat distance moderates this interactive optimism association. In two studies, participants were randomly assigned to a looming or distant threat condition. Study 1 revealed that in the looming threat condition, participants high in both forms of optimism were more likely to minimise the threat and less inclined to seek additional health information relative to participants high in dispositional but low in comparative optimism. In Study 2, the same interaction pattern emerged on a measure of psychological abstraction suggesting these variables combine to alter broad information processing strategies. Implications for considering multiple forms of optimism when delivering health status information are discussed.  相似文献

Background: Burnout and chronic fatigue syndrome (CFS) are two fatigue syndromes which have developed largely independently from each other, yet whose similarities in symptoms can be a source of confusion. We aim to explore the phenomenology of burnout and CFS in a historical context as this may provide some insight into the links and relationship between these conditions. Method: A narrative review based on literature in the fields of history, social science and medicine. Results: The origins of CFS lie within medicine, whereas burnout developed in a psychological setting. As well as symptoms, burnout and CFS also share similar themes such as an overload process triggering illness onset, the need for restoration of depleted energy, external causal attributions and the characteristics of people suffering from these illnesses. However, these themes are expressed in either psychological or medical terms according to the historical background. Conclusion: Despite their similarities, there have been few direct comparisons of the two concepts. Culture, illness perceptions and accountability are important issues in both conditions and could contribute to their differences. Comparing burnout and CFS within one sample frame, thus looking beyond the psychology/medicine divide, could be a useful first step towards understanding their relationship.  相似文献

This article describes the relationship between HIV testing and a range of psychosocial, sexual and socio-demographic variables. Trained research staff distributed a self-report questionnaire in the gay bars of Glasgow and Edinburgh, in May 2000. Questionnaires were completed by 803 men (a response rate of 78%). We present the results of both bivariate and multivariate analyses identifying key variables associated with never having had an HIV test. Thus we outline some psychosocial barriers to HIV testing. Multivariate analysis indicated that the most important factor associated with never having tested was fear of a positive result; this was particularly true for those men who reported higher levels of risky sexual conduct. We discuss the relevance of these findings in terms of presenting a psychosocial agenda which demands that stigma and the social exclusion of HIV positive people should be addressed before gay men are encouraged to seek HIV testing.  相似文献

Objectives: Although a wide literature details the psychological impact of human immunodeficiency virus (HIV) diagnosis, it predates the introduction of effective treatment for HIV (i.e. anti-retroviral therapies, ARTs). This article explores the psychological impact of HIV diagnosis in post-ART accounts. This is important, given the recent policy developments which focus upon increasing HIV testing and thus diagnoses.

Design: This study presents a qualitative exploration of the experiential accounts of HIV-positive gay men living in Scotland. A total of 14 HIV-positive gay men took part in open-ended interviews.

Methods: Interpretative phenomenological analysis was employed to identify recurrent themes across the interviews.

Results: Our analysis focuses upon the participants’ struggles in adjusting to their HIV status. Diagnosis was a deeply shocking and unexpected experience. Stigma and fear of prejudice dominated their accounts. HIV was understood, variously, as a shameful, fatal and life-changing condition. Overall, within these accounts there was little sense of HIV normalisation.

Conclusions: In Scotland, where HIV prevalence is low, and where no accessible HIV-positive sub-culture exists, there is on-going psychological distress and morbidity amongst gay men testing HIV positive. As HIV-related policy increasingly focuses on increasing rates of antibody testing, there is a need to reduce the psychosocial costs associated with HIV-positive diagnoses.  相似文献

Posttraumatic stress disorder (PTSD) has been associated with deficits in the areas of verbal memory and learning, executive functioning, working memory, and attention in adults. Findings have been less consistent in the few studies examining neuropsychological functioning in childhood PTSD, which are often limited by comparing children with PTSD to children without trauma histories, making it unclear whether observed neuropsychological deficits are related to trauma exposure or to PTSD symptomatology. In an ethnically diverse sample of 62 children who witnessed intimate partner violence (n = 27 PTSD+ and 35 PTSD?), children with PTSD exhibited slower and less effective learning, heightened sensitivity to interference, and impaired effect of rehearsal on memory acquisition on the California Verbal Learning Test – Children's Version, a word list learning task. Both groups performed in the below average range on measures of executive functioning, attention, and intellectual ability.  相似文献

Abstract

Although cognitive dissonance is regarded as one of the most recognized causes of selective exposure [N. J. Stroud, Niche News (Oxford University Press, 2011)], the mechanism for such causation is still unclear. By inducing dissonance in a web-based experiment, this study demonstrates how cognitive dissonance relates to information preferences—the intention to seek congruent information and the intention to seek incongruent information. The findings suggest that perceived hostility with respect to one’s belief (cognitive discrepancy) can enhance the intention to seek out for attitude-consistent information. More importantly, individuals were found to have the intention to avoid counterattitudinal information, but only when they experienced some sort of psychological discomfort (dissonance). In other words, while cognitive discrepancy leads individuals to crave for confirming information, only those who encounter negative emotions are likely to employ avoidance of disconfirming information as a dissonance-reduction strategy.  相似文献

Conflicting theoretical approaches yield divergent predictions about the effects of telephones versus computer-mediated communication (CMC) in the persistence or dissipation of pre-interaction expectancies. Moreover, different theoretical orientations and their underlying assumptions often invoke different methodologies, which can bias the results of research. The current studies articulate and assess rival hypotheses from alternative theoretical paradigms to uncover how CMC and vocal communication affect interpersonal impressions. Methodological issues in past CMC research are evaluated that limit the generalizability of previous findings in the area. Experiments employing alternative assumptions and methods indicate that CMC is functionally equivalent to vocal communication in its ability to ameliorate expectancies and that in some cases it can be superior in transmitting positive impressions.  相似文献

A simple “expression” account of the relation between executive function (EF) and children's developing theory of mind (ToM) has difficulty accounting for the generality of the changes occurring in children's mental-state understanding during the preschool years. The current study of preschool children (N = 43) showed that EF—especially conflict EF—related uniformly to ToM measures that imposed either high or low executive demands, independent of verbal ability. These findings can be explained within an emergence account wherein executive skills are implicated in the acquisition of mental-state concepts as opposed to merely the expression of these concepts in task performance.  相似文献

Attributions are constantly assigned in everyday life. A well-known phenomenon is the self-serving bias: that is, people’s tendency to attribute positive events to internal causes (themselves) and negative events to external causes (other persons/circumstances). Here, we investigated the neural correlates of the cognitive processes implicated in self-serving attributions using social situations that differed in their emotional saliences. We administered an attributional bias task during fMRI scanning in a large sample of healthy subjects (n = 71). Eighty sentences describing positive or negative social situations were presented, and subjects decided via buttonpress whether the situation had been caused by themselves or by the other person involved. Comparing positive with negative sentences revealed activations of the bilateral posterior cingulate cortex (PCC). Self-attribution correlated with activation of the posterior portion of the precuneus. However, self-attributed positive versus negative sentences showed activation of the anterior portion of the precuneus, and self-attributed negative versus positive sentences demonstrated activation of the bilateral insular cortex. All significant activations were reported with a statistical threshold of p ≤ .001, uncorrected. In addition, a comparison of our fMRI task with data from the Internal, Personal and Situational Attributions Questionnaire, Revised German Version, demonstrated convergent validity. Our findings suggest that the precuneus and the PCC are involved in the evaluation of social events with particular regional specificities: The PCC is activated during emotional evaluation, the posterior precuneus during attributional evaluation, and the anterior precuneus during self-serving processes. Furthermore, we assume that insula activation is a correlate of awareness of personal agency in negative situations.  相似文献
