Direct biofeedback of blood pressure was compared with frontal EMG biofeedback and with self-instructed relaxation for the treatment of essential hypertension in a controlled group outcome study. Patients were followed up for four months after the end of treatment. Generalization of treatment effects was assessed through pre- and posttreatment measurements of blood pressure under clinical conditions in a physician's office. There were no significant reductions in diastolic blood pressure. The systolic blood pressure (SBP) of the patients receiving blood pressure biofeedback decreased 8.1 mm mercury (p = 0.07) and the SBP of the patients in the relaxation condition decreased 9.5 mm mercury (p = 0.05). In the generalization measures, there were significant reductions in SBP for the relaxation group. The results are discussed in terms of the general lack of replicability within the area of biofeedback treatment of hypertension. 相似文献

The multiprocess view proposes that different processes can be used to detect event-based prospective memory cues, depending
in part on the specificity of the cue. According to this theory, attentional processes are not necessary to detect focal cues,
whereas detection of nonfocal cues requires some form of controlled attention. This notion was tested using a design in which
we compared performance on a focal and on a nonfocal prospective memory task by participants with high or low working memory
capacity. An interaction was found, such that participants with high and low working memory performed equally well on the
focal task, whereas the participants with high working memory performed significantly better on the nonfocal task than did
their counterparts with low working memory. Thus, controlled attention was only necessary for detecting event-based prospective
memory cues in the nonfocal task. These results have implications for theories of prospective memory, the processes necessary
for cue detection, and the successful fulfillment of intentions. 相似文献

Optimism and hope—two psychological constructs reflecting positive expectations about one’s future—have garnered considerable research attention and each has been the subject of several narrative reviews. In the current meta-analysis, we examined the optimism–hope relationship and we examined several potential correlates and consequences of optimism and hope. Our results suggest that optimism and hope are distinguishable from each other. Furthermore, both are related to several indices of psychological and physical well-being and both are empirically distinguishable from other personality traits, such as the Five Factor Model characteristics and trait affectivity. We conclude by discussing directions for future research on optimism and hope. 相似文献

Individuals infected with human immunodeficiency virus (HIV) are at elevated risk for depressive conditions, which in turn can negatively impact health-related behaviours and the course of illness. The present study tested the role of autobiographical memory specificity and its interaction with perceived stress in the persistence of depressive symptoms among dysphoric HIV-positive individuals. Additionally, we examined whether rumination and social problem solving mediated these effects. Results indicated that memory specificity moderated the impact of perceived stress, such that perceived stress was more strongly associated with follow-up depressive symptoms among those with greater memory specificity. Rumination, but not social problem solving, mediated this effect. Implications of these findings are discussed. 相似文献
