The article presents an operationalized and manualized approach for the assessment of the capability of performance. This manual has been conceptualized and tested empirically by a multicentric and interdisciplinary workgroup. It is basically oriented to the “International Classification of Functioning” (ICF; WHO), which is well accepted for assessing the course of chronic diseases and the consequences for the individual. It is especially widely applied in the context of rehabilitation. The different diagnostic levels of the manual and their operationalization are outlined. Furthermore, the first results concerning reliability, content validity, applicability and practicability are described and questions on the areas of application of the instrument are discussed. 相似文献

Cognitive processes are assumed to change with learned helplessness, an animal model of depression, but little is known about such deficits. Here we investigated the role of cognitive and related functions in selectively bred helpless (cLH, n = 10), non-helpless (cNLH, n = 12) and wild type (WT, n = 8) Sprague Dawley rats. The animals were exposed to an open field for 10 min on each of two test days. On the third day, an object exploration paradigm was carried out. The animals were later tested for helplessness. Both cLH and cNLH rats were more active than WTs on the first day in the open field. Over trials, cNLH and WT rats lowered their activity less than cLH rats. This resistance-to-habituation co-varied with a resistance to develop helplessness. In cLH rats, higher ‘anxiety’ or less time spent in the center of the open field co-varied with severe helplessness. In WTs, a greater reactivity to novel objects and to a spatially relocated object predicted lower levels of helplessness. In cLH rats (n = 4–5 per group), chronic treatment with a high dose of the monoamine oxidase (MAO)-B inhibitor deprenyl (10 mg/kg; i.p.), an anti-Parkinson, nootropic and antidepressant drug, attenuated helplessness. Remarkably, helplessness reversal required the experience of repeated test trials, reminiscent of a learning process. Chronic deprenyl (10 mg/kg; i.p.) did not alter locomotion/exploration or ‘anxiety’ in the open field. In conclusion, helplessness may be related to altered mechanisms of reinforcement learning and working memory, and to abnormalities in MAO-A and/or MAO-B functioning. 相似文献

Dual Identification and the (De‐)Politicization of Migrants: Longitudinal and Comparative Evidence 下载免费PDF全文

The article examines the role of dual identification with both the ethnocultural ingroup and the society of residence in the politicization of migrants. The researchers employed a longitudinal and comparative research design with members of the two largest, but sociologically very different, migrant groups in Germany as research participants (i.e. Turkish migrants and Russian migrants). In line with prior work that has shown that, among members of aggrieved groups, dual identity functions as a politicized collective identity, we found that dual identification fostered political engagement among Turkish migrants. In contrast, Russian migrants reported no substantial grievances, and dual identification negatively affected their subsequent political engagement. The contributions of these findings to an articulation of research on politicization with research on intergroup conflict and a more comprehensive understanding of political phenomena driven by dual identification are discussed.

The presence of posttraumatic stress disorder (PTSD) symptoms and posttraumatic growth (PTG) following a critical incident were examined among firefighters from eight predominantly European countries. A sample of 1916 firefighters completed the Impact of Event Scale–Revised (IES–R) and the Posttraumatic Growth Inventory–Short Form (PTGI–SF) with reference to a critical incident they had experienced. Analyses indicated both negative and positive posttraumatic outcomes could derive from experiencing critical incidents in the line of duty. The analyses also showed country differences exist regarding firefighters’ PTSD symptoms and PTG. It is recommended that future researchers examine factors that could evoke such national differences. 相似文献

Fear responses can be eliminated through extinction, a procedure involving the presentation of fear-eliciting stimuli without aversive outcomes. Extinction is believed to be mediated by new inhibitory learning that acts to suppress fear expression without erasing the original memory trace. This hypothesis is supported mainly by behavioral data demonstrating that fear can recover following extinction. However, a recent report by Myers and coworkers suggests that extinction conducted immediately after fear learning may erase or prevent the consolidation of the fear memory trace. Since extinction is a major component of nearly all behavioral therapies for human fear disorders, this finding supports the notion that therapeutic intervention beginning very soon after a traumatic event will be more efficacious. Given the importance of this issue, and the controversy regarding immediate versus delayed therapeutic interventions, we examined two fear recovery phenomena in both rats and humans: spontaneous recovery (SR) and reinstatement. We found evidence for SR and reinstatement in both rats and humans even when extinction was conducted immediately after fear learning. Thus, our data do not support the hypothesis that immediate extinction erases the original memory trace, nor do they suggest that a close temporal proximity of therapeutic intervention to the traumatic event might be advantageous. 相似文献

In the search for animal models of human geriatric depression, we found that operant extinction of escape from water results in the expression of immobility in different age groups, indicative of behavioral "despair", which was also associated with the resistance-to-extinction (RTE) expressed by these animals. With respect to the neurotrophin hypothesis of depression, nerve-growth factor (NGF), brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) protein levels in frontal cortex (FC) and hippocampus (HP) were examined and related to behavioral immobility and RTE in the water maze in aged and adult Wistar rats. Age-related increases in levels of NGF were found in HP and of NT-3 in FC. Indices of immobility showed relationships in the aged with NGF and, in adults, with BDNF, pointing to a dissociation of neurotrophic involvement in extinction trial-induced "despair" in aged and adult rats. The present results support the hypothesis, that extinction-induced immobility in the water maze reflects a state akin to behavioral despair and point to age-related differences of neurotrophic involvement in depressive-like symptoms. The concept of extinction-induced behavioral "despair" in the aged subsumes several aspects of human geriatric depression, such as co-morbidity of learning impairment and anxiety, and, thus could represent a useful paradigm to examine the neuronal mechanisms underlying depression, especially in aged rodents. 相似文献

The theories of social conduct, seriousness of need, and similarity; cost–benefit models; and individual differences in ideology are used to predict self‐reported help giving that is interpersonal or through humanitarian organizations. The results indicate that persons tend to be more helpful interpersonally than through organizations, are more responsive to characteristics of the needy when helping interpersonally than through organizations, and have stronger affective responses toward individuals than toward individuals represented by organizations. For both interpersonal and organization‐mediated assistance, perceived benefit to the donor strongly predicts help giving. Relatively conservative persons report less helpfulness, both interpersonally and through humanitarian organizations. Collectively, these findings offer an integrative approach to help giving and have implications for fundraising in the humanitarian sector. 相似文献
