We argue that affect plays a vital role in attitudes toward organ donation and that reluctance to become an organ donor is likely to be related to the experience of affective ambivalence. Assessing the affect associated with organ donation could help to predict donor-relevant decisions. Results of a confirmatory factor analysis on 464 students showed that affective evaluations can be distinguished both from cognitive evaluations and from overall evaluations. As expected, affective evaluations revealed ambivalence (using the ‘Griffin’ measure of ambivalence) toward organ donation, whereas the two other types of evaluations did not. Results of a follow-up study using logistic regression (n?=?85), showed that affective evaluations predicted donor-relevant decisions six months later. The present findings support the proposal to include separate affective evaluations in measures of attitudes to organ donation. More general implications for the measurement and structure of attitudes in health related domains are discussed. 相似文献

Abstract Persons scoring high on negative affectivity (NA) have more subjective health complaints. In this study, we tested the hypothesis that high NA persons are more likely to experience internal sensations as threatening signs of health problems. Low and high NA participants (N=44) were given four breathing trials: one room air trial followed by three trials containing 5.5% CO2 which induced transient low intensity somatic sensations. Prior to each CO2 trial, participants received either positive, negative or uncertain labelings of the sensations that might occur. Participants rated the (un)pleasantness of the experienced somatic sensations and the perceived intensity. Also respiratory responses were measured. During CO2 trials, reliable main effects of information were found but no effects involving NA were observed, neither on pleasantness ratings nor on respiratory responses. However, during room air breathing, high NA participants reported more intense somatic sensations than low NA participants. Post-experimental data suggested that high NA participants had more negative meanings and worries about the consequences of the physical sensations. It is concluded that interpretational biases in high NA is situated at the level of attributional processes. 相似文献

Abstract The utility of a modified health belief model (Janz and Becker, 1984) for predicting the intention to use condoms was tested in a study among gay and bisexual men. The model explained a reasonable amount of variance. It was found that younger men's decision to have safe sex was guided by factors other than those that influenced older men. Among younger men, the intention to use a condom was positively related to the relative number of persons with AIDS in their social environment (cues to action) and to the perceived benefits of HIV preventive behavior. Among older men, this behavioral intention was much more determined by their perception of the prevalence of HIV and by their perception of their vulnerability to HIV infection. These findings are important because they may partly explain the recent increase in AIDS-risk behavior among young gay and bisexual men. The discussion focuses on these findings and on the implications for interventions aimed at promoting safe sex. 相似文献

Both children with epilepsy and children with ADHD may be characterized by slowing on reaction-time measurement. This is of particular interest, as neuropsychological assessment is often requested in the differential diagnosis between children with short non-convulsive epileptic seizures and children with ADHD. In this study we attempt to identify patterns of impairment on timed tasks that are specific for epilepsy, relative to ADHD. This study was an open, controlled parallel-group clinical investigation which included two groups of patients: 60 children with ADHD and 60 children with epilepsy. These children were compared with a control group (n =30) on two types of timed cognitive tasks: tasks with low information load (simple reaction-time measurement) and tasks with high information load (multiple decision reaction-time measurement). The simple reaction-time measurements show significant differences between ADHD and controls (all except for visual RT non-dominant hand) and between epilepsy and controls (only one test). No significant differences were found between epilepsy and ADHD. The two tests with high information load show significant slowing compared with the controls for epilepsy on the Binary Choice Reaction-Time Test and for ADHD on the Visual Searching Test. On both tests also the differences between epilepsy and ADHD are significant. The two tests in combination have a relatively satisfactory potential to classify the children with ADHD (75% correct classification) and the children with epilepsy (55% correct classification). We may conclude that complex reaction-time tests (i.e., timed tasks with high information load) have potential for assessing the differential impact of ADHD and epilepsy on attentional function. These tasks specifically reveal general slowing for children with epilepsy and slowing as an effect of failures of inhibitory self control on unstructured tasks for ADHD. 相似文献

Retrieving information from memory improves recall accuracy more than continued studying, but this testing effect often only becomes visible over time. In contrast, the present study documents testing effects on recall speed both immediately after practice and after a delay. A total of 40 participants learned the translation of 100 Swahili words and then further restudied the words with translations or retrieved the translations from memory during testing. As in previous experiments, recall accuracy was higher for restudied words than for tested words immediately after practice, but higher for tested words after 7 days. Response times for correct answers, however, showed a different result: Learners were faster to recall tested words than restudied words both immediately after practice and after 7 days. These results are interpreted in light of recent suggestions that testing selectively strengthens cue–response associations. An additional outcome was that testing effects on recall accuracy were related to perceived retrieval success during practice. When several practice retrievals were successful, testing effects on recall accuracy were already significant immediately after practice. Together with the reaction time data, this supports recent models that attribute changes in testing effects over time to limited item retrievability during practice. 相似文献

In order to relate expertise in business computer science to multiple criteria, the importance of competencies, as elements of expertise, for the performance of tasks and roles were investigated. Seventy-five information technology professionals (nine women and sixty-six men) from twenty-one organizations rated the importance of thirty-four competencies for the performance of eighty-six tasks and seven roles. In accordance with previous studies, knowledge of information technology, working methodically, and analytic ability were rated as important competencies for most types of tasks, and social skills were especially important for tasks related to interaction with the environment and leadership roles. By means of cluster analysis, four work domains were discerned: technique-oriented, organization-oriented, leadership-oriented, and user-support-oriented domains. It is argued that relating competencies to work domains has theoretical and practical relevance. 相似文献

Incidence rates of third party workplace violence in Europe have increased, but little is known about the causes thereof. It has been suggested that the growth of the service sector and the intensification of work could be responsible for the increase. This study aimed to identify trends in the prevalence of physical workplace violence across Europe, as well as to uncover factors explaining these trends. Three cross-sectional waves (1995, 2000, and 2005) of the European Working Conditions Survey were used, involving 58,520 workers and covering 15 European member states. Logistic regression analyses were performed to investigate associations between work characteristics and violence prevalence. Workplace violence increased significantly during the study interval. Although violence was clearly related to specific characteristics of the labour market (gender, age, sector, etc.) and the work environment (client contact frequency, time pressure, control, and computer work), recent changes in the European labour market composition and work environment could not explain the increase in violence. In jobs characterized by high levels of computer work in particular, violence appears to be an emerging risk. Our results suggest that the nature (and perhaps quality) of client contact is changing, leading to higher violence risks. 相似文献

Most studies relating charismatic leadership to performance have limitations concerning selection of criterion measures and investigation of moderators. Therefore, this study examines relationships between charismatic leadership and multiple performance outcomes under different levels of environmental dynamism (i.e., level of environmental uncertainty, degree of technological change) and per type of Chief Executive Officer (firm owner versus managing director). Results revealed that charismatic leadership was positively related to common-source and multi-source perceptual performance outcomes (i.e., subordinates' positive work attitude) and to organization profitability, but unrelated to organization liquidity and solvency. The relationship between charismatic leadership and perceptual performance was stronger under conditions of environmental uncertainty than under conditions of environmental certainty. Furthermore, charismatic leadership was more strongly related to organization profitability for firm owners than for managing directors who do not own their firm. The results are discussed and several potentially fruitful avenues for future research on charismatic leadership and employee as well as organizational performance are presented. 相似文献
