Metacognitive therapy (MCT) is based on over 25 years of research focusing on the processes that contribute to the development and maintenance of psychological disorders. The approach identifies a common set of processes in psychopathology, and MCT shows promising results in effectively treating a range of disorders. This paper presents the central theoretical tenets of MCT and uses a clinical vignette to illustrate the structure and techniques of treatment based on Wells's (2009) manual as they relate to a specific case of generalized anxiety disorder. 相似文献

Child abuse predicts a wide range of long-lasting deleterious outcomes, including disruptions in the biological systems central to emotion arousal and regulation. However, little is known about the specific ways in which child abuse affects adulthood sympathetic reactivity and recovery. This study investigated the association between child abuse experience and adult skin conductance level and habituation in 85 at-risk women as they completed a self-report trauma questionnaire. Childhood emotional abuse was independently associated with blunted skin conductance habituation over the course of survey completion after controlling for other abuse subtypes and current trauma symptoms. These results suggest that women emotionally abused as children experience prolonged emotional arousal and poor physiological regulation of emotion in response to reminders of traumatic experiences. 相似文献

The present study examined the role of religious coping in psychological distress and adjustment both cross-sectionally and longitudinally among 141 HIV-positive African American women. Cross-sectional analyses showed that negative religious coping was associated with poorer mental health and functioning, and greater perceptions of stigma and discrimination. Longitudinal analyses revealed that greater negative religious coping at baseline significantly predicted greater changes in mental health in a negative direction 12 months later. Positive religious coping was not associated with any measures of psychological well-being, nor did it predict any mental health outcomes at 12 months. However, participants who experienced high levels of HIV-related stigma and reported high levels of positive religious coping were less depressed than those who reported lower levels of positive religious coping. These results suggest that for this population, negative religious coping was a more salient determinant of psychological distress than positive religious coping was of psychological health. 相似文献

The effects of interference on memory in younger and older adults were examined in a series of three experiments. In the study task, subjects were presented with a series of sentences, each having both a target, to-be-remembered ending, and a nontarget ending. Older adults showed equal priming of targets and nontargets on an indirect memory test (Experiment 1), whereas younger adults showed greater priming of the targets. In contrast, on direct memory tests (Experiments 2 and 3) both age groups were more accurate for targets than nontargets. This pattern of results is interpreted as evidence that age differences in interference involve selective attention mechanisms, but not elaborative rehearsal processes. 相似文献

Previous investigations of the ability to maintain separate attentional control settings for different spatial locations have relied principally on a go/no-go spatial-cueing paradigm. The results have suggested that control of attention is accomplished only late in processing. However, the go/no-go task does not provide strong incentives to withhold attention from irrelevant color–location conjunctions. We used a modified version of the task in which failing to adopt multiple control settings would be detrimental to performance. Two RSVP streams of colored letters appeared to the left and right of fixation. Participants searched for targets that were a conjunction of color and location, so that the target color for one stream acted as a distractor when presented in the opposite stream. Distractors that did not match the target conjunctions nevertheless captured attention and interfered with performance. This was the case even when the target conjunctions were previewed early in the trial prior to the target (Exp. 2). However, distractor interference was reduced when the upcoming distractor was previewed early on in the trial (Exp. 3). Attentional selection of targets by color–location conjunctions may be effective if facilitative attentional sets are accompanied by the top-down inhibition of irrelevant items. 相似文献

Unilateral stroke results in hemiplegia or hemiparesis of the contralateral side of the body. The ipsilateral side of the body, the so-called "good" side, is often assumed to have no deficit. However, there is increasing evidence that the function of the unaffected limbs, especially the upper extremities, is different from that of normal age-matched controls. In the present study, we examined the motor control of both hands of chronic stroke subjects, 6 with left hemisphere brain damage (LHBD) and 5 with right hemisphere brain damage (RHBD). The control group consisted of 5 normal age-matched subjects. The task of the subject was to move a handle by flexing his/her fingers until the target position was reached. The target position was set as 33% of the range of each subject. No time constraints were imposed. The movements of the normal subjects were basically smooth, with few hesitations. In contrast to this, the movements of both hands in the two stroke groups were segmented and characterized by multiple starts and stops. As compared to normals, the time to reach the target, the number of pauses during the movement, and the percent of time spent in pauses, were significantly greater for both hands of the LHBD group. In the RHBD group, the percent of time spent in pauses was significantly greater than the control group for the ipsilesional hand. The increased segmentation seen in the movements of the ipsilesional, as well as the contralesional. hands of the hemiplegic subjects suggests that the motor deficits in stroke patients may be due to a global inability to correctly plan and carry out movements. 相似文献

Bioremediation is an innovative approach to environmental management that uses microorganisms or plants to clean up toxic contamination in the environment. This research examines public attitudes toward the use of bioremediation at 2 sites in California: an urban site (Avila Beach) and a natural site (Guadalupe Dunes). At both sites, the study participants preferred excavation of the contaminated soil to bioremediation. The survey results help to explain the reasons why there is limited support for the use of bioremediation. 相似文献

Experimental results on individuals' preferences for temporal sequences of environmental outcomes related to air quality and near-shore ocean water quality are compared with preferences for sequences of health and monetary outcomes. Generally, graduate business student participants gave significantly lower ratings to environmental and health sequences (with equal means) that worsened over time, relative to the ratings they gave to sequences that either remained the same or improved over time. This pattern was reversed by the participants when they faced sequences of monetary payments. This preference structure held for both short (5-year) and long (50-year) time horizons, and it was confirmed with choice data. A model proposed by Loewenstein and Prelec for the valuation of sequences of outcomes was applied to the current data set and compared to the traditional discounting model. In all cases, the model that incorporated “Gestalt” features of the sequence (slope and uniformity) performed better than the net present value discounting model at predicting the mean ratings for the sequences in the different domains. 相似文献
