This open trial investigated the transdiagnostic effects of metacognitive therapy (MCT) in patients with severe major depressive disorder and comorbid psychiatric disorder. Ten patients were treated with MCT over 10 sessions and were assessed with measures of depression, anxiety, rumination, and metacognitions at pre- and posttreatment and at 6 months follow-up. None of the patients were diagnosed as depressed at posttreatment, and of the initial 21 total diagnoses at pretreatment only 3 diagnoses remained at postintervention. The effect sizes were large for symptoms of depression, rumination, and worry. At 6 months follow-up standardized recovery criteria on the BDI showed that 70% were recovered, 20% improved, and 10% unchanged. The results indicate that MCT was associated with high rates of transdiagnostic improvement. 相似文献

A questionnaire measuring sexual attitudes, attitudes about women, and racial attitudes was administered to 350 White male college students. Sexual attitudes characterized by sexual guilt, emphasis on personal and social control of sexual expression, and depersonalization of sex were significantly positively correlated (p<.001) with attitudes that typified women in terms of traditional masculine—feminine stereotypes and good (nonsexual)—bad (sexual) dichotomies. These stereotyped and dichotomous attitudes about women and constricted and depersonalized sexual attitudes were both significantly positively correlated (p<.001) with negative racial attitudes. The implications of these results and other research suggested by this investigation are discussed.This report is based on a dissertation submitted in partial fulfillment of the requirements for the Ph.D. degree at Michigan State University, 1973. The author would like to express appreciation to Dozier W. Thornton for continued guidance and assistance as dissertation advisor. In addition, the author gratefully acknowledges the assistance of Donald L. Grummon, Andrew M. Barclay, and Jeanne E. Gullahorn, all of whom served on the dissertation committee. 相似文献

Theological thinking is influenced by perspectives on the relation of scientific knowledge to reality. Two paradigms for understanding the nature of human knowledge are considered in relation to quantum mechanics: the subjective-observing perspective of Kant, and the objective-participant perspective of Thomas Aquinas. I discuss whether quantum mechanics necessarily implies a subject centered perspective on reality, and argue, with reference to d'Espagnat's notion of veiled reality, that quantum non-separability challenges this view. I then explore whether the objective-participant perspective of Thomas Aquinas provides a more fruitful context for understanding quantum mechanics. I discuss quantum measurement in terms of the transition from potentiality to actuality, and knowledge as the latent intelligibility of the world realized. However, the negative nature of our knowledge of quantum non-separability also challenges this perspective. Our theological thinking in response to quantum knowledge must therefore proceed tentatively, balancing a via positiva, with a via negativa. 相似文献

Assessment of risk is one of the key issues in the field of responsible conduct of research which covers discourses of research ethics and research integrity. The principle of minimizing risks and balancing of risks and benefits is one of the main requirements of research ethics. In addition, the content of informed consent that is another fundamental principle of research ethics derives from the assessment of risks and benefits related to a particular research project. Risk assessment also plays a crucial role in methodological design of the research project. This is an important point where research ethics and research integrity discourses overlap. Firstly, because the choice of a control group (e.g., placebo control) is a key ethical issue related to the protection of the research subjects' interests. Secondly, because the quality of the research data, that is one of the key elements of research integrity, is closely connected to the choice of research methodology as well. The problem of biased interpretation or manipulation of risk related features of biomedical research should also be taken into account. Despite the importance of the concept of risk to the field of biomedical research, its relevance has not yet attracted a sufficient attention in the responsible conduct of research debate. 相似文献

This investigation extends previous research documenting differences in Chinese and European American infants' facial expressivity. Chinese girls adopted by European American families, nonadopted Mainland Chinese girls, nonadopted Chinese American girls, and nonadopted European American girls responded to emotionally evocative slides and an odor stimulus. European American girls smiled more than Mainland Chinese and Chinese American girls and scored higher than Mainland Chinese girls for disgust-related expressions and overall expressivity. Adopted Chinese girls produced more disgust-related expressions than Mainland Chinese girls. Self-reported maternal strictness, aggravation, positive expressiveness, and cultural identification correlated with children's facial responses, as did number of siblings and adults in the home. Results suggest that culture and family environment influences facial expressivity, creating differences among children of the same ethnicity. 相似文献

Observers made speeded old-new recognition judgments of color stimuli embedded in a multidimensional similarity space. The paradigm used multiple lists but with the underlying similarity structures repeated across lists, to allow for quantitative modeling of the data at the individual-participant and individual-item levels. Correct-rejection response times (RTs) got systematically faster as the similarity of foils to the old study items decreased. There were also intricate patterns of speed-accuracy trade-offs that varied across individual items and participants. An exemplar-based random-walk model provided a good overall quantitative account of the recognition choice probabilities, mean correct RTs, and mean error RTs associated with the individual items on the basis of their positions in multidimensional similarity space. However, the model failed to predict the very long RTs associated with correct rejections of a prototype foil. 相似文献

In many non‐human primate species, a display of red by a female increases attraction behavior in male conspecifics. In two experiments, we investigate an analogous effect in humans, specifically, whether red on a woman's shirt increases attraction behavior in men. In Experiment 1, men who viewed an ostensible conversation partner in a red versus a green shirt chose to ask her more intimate questions. In Experiment 2, men who viewed an ostensible interaction partner in a red versus a blue shirt chose to sit closer to her. These effects were observed across participants' perceptions of their own attractiveness (Experiment 1) and general activation and mood (Experiment 2). Our findings suggest that red acts as a basic, non‐lexical prime, influencing reproduction‐relevant behavior in like manner across species. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献
