Addressing women's breast cancer risk and perceptions of control in medical settings 总被引:1,自引:0,他引:1

Many women with family histories of breast cancer deal with two distinct but related issues: their objective physical risk and the emotions this risk engenders. Studies indicate that approximately 70% of African American and white women are concerned about their chances of developing breast cancer someday and perceive themselves to be at risk. Health care providers, including psychologists, need to be aware of the special needs and psychosocial concerns of high-risk women with family histories of breast cancer, since perceptions of breast cancer risk influence screening practices. Providers need training in understanding the significance of specific family patterns of breast cancer, screening guidelines appropriate for women at risk, and the benefits and risks of available prevention options, including genetic screening. Delivering accurate information about both established risk factors known to elevate personal risk, such as age and family history, and factors which women associate with breast cancer, such as bumping and bruising a breast, smoking, and oral contraceptive use, is essential for promoting accurate risk perceptions and appropriate screening schedules. 相似文献

Casuistry is a traditional method of interpreting and resolving moral problems. It focuses on the circumstances of particular cases rather than on the application of ethical theories and principles. After a brief history of casuistry, the method is explained and its relation to theory and principles is discussed. 相似文献

This article reports the results of a questionnaire study that examined the relationship between regional identification and perceptual accentuation of ingroup distinctiveness in a natural field setting. Respondents were male inhabitants of the Saarland which is a small German state. Half the respondents were members of the leading political party of the Saarland, while the other respondents were members of the major opposition party. As expected, the former showed more pronounced regional identification than the latter. Our main prediction was that a higher level of regional identification would be accompanied by stronger accentuation of positive distinctiveness of the regional ingroup relative to the national ingroup. The prediction was confirmed, both in terms of intergroup differentiation and perceived group homogeneity. Additional results suggest that, depending on the level of social identification, perceived group homogeneity may be either positively or negatively related to familiarity with the ingroup. Finally, we discuss the applicability of social identity theory to social contexts comprising differentially inclusive ingroups instead of mutually exclusive ingroups and outgroups. 相似文献

Une série d'études inter-culturelles a été consacrée à L'effet de L'équité sur le comportement de choix, dans un jeu de type Dilemme du Prisonnier. Les résultats antérieurement collectés montrent que les sujets américains choisissent de maximiser leur gain en fonction de leur niveau d'estime de soi: une distribution des récompenses en fonction du mérite semble correspondre à un besoin d'équité; mais les sujets italiens qui ont une faible estime d'eux-mêmes tendent à maximiser plus fréquemment leur gain: ils ont tendance à être “ ego-défensifs”. Dans les études qui sont présentées ici, une récompense initiale est donnée à L'un des deux partenaires, sur la base d'un “test” d'aptitude à la prédiction (Distribution Juste), ou bien la récompense est donnée arbitrairement, sans tenir compre du test (Distribution Injuste). Les sujets doivent ensuite faire une serie de cinquante choix. Les choix des sujets américains renètent un besoin d'équité dans la condition Distribution Injuste, le sujet qui a reçu une récompense choisit moins souvent de maximiser ses gains que le sujet qui n'a pas reçu de récompense; dans la condition Distribution Juste, les sujets maintiennent L'inégalité créée par la récompense initiale. Sur L'ensemble des trois échantillons italiens qui ont été étudiés séparément, on observe une tendance à minimiser L'injustice dans la condition Distribution Injuste; mais dans la condition Distribution Juste, on observe un effet de défense du moi. Différentes interprétations théoriques des résultats sont discutées. 相似文献

This article describes a solid state apparatus for use in 2 by 2 game research. There are two individual player’s boards and a control panel for E. Following E’s signal, each player chooses one of two responses. Their choices are immediately registered on E’s panel, but appear on each individual game board only after both have responded. Provisions are made for E to transmit false feedback. 相似文献

Pupil size was measured while 30 male college students undertook five tasks respectively concerning, (a) muscle tension induced by the lifting of weights, (b) fear induced by threat of a gunshot, (c) intense stimulation induced by loud pure tones, (d) heightened attention from viewing novel pictures, and (e) pleasantness and unpleasantness in reaction to pictures that differed in terms of their affect-inducing characteristics. Highly regular relationships were found between pupil size and degree of muscle strain and between pupil size and the temporal ordering of events during threat of a gunshot. Significant effects on pupil size also were found for the other three types of stimulation. 相似文献

Mean ability levels as measured by high school rank and scholastic aptitude test scores were computed for freshman classes at 38 colleges in Minnesota. The mean grade-point averages achieved by these freshman classes were also obtained. By comparing mean ability level with mean grade-point, a “difficulty index” was computed for each college. The validity of the index was tested by using it to predict differences in grades achieved by students who transferred from one college to another and comparing such predicted grades with those actually achieved after transfer. Difficulty indexes computed by this method predicted differences in mean grade-point averages of transfer students with surprising accuracy. 相似文献

Four pigeons were trained on a multiple reinforcement schedule consisting of two limited-hold schedules, one in which a discriminative stimulus (SD) accompanied the periodic reinforcement contingency, and one in which the discriminative stimulus was omitted. The duration of the limited-hold in each component of the multiple schedule was reduced in parallel steps. It was shown that behavioral differences between the two schedules were attenuated by this manipulation of temporal parameters. When SD was reduced in duration, three out of four pigeons responded with extremely high SΔ rates, despite the regular pairing of SΔ with the reinforcement contingency. These high rates qualitatively resembled the rapid rates emitted on the analogous no-SD component. 相似文献
