Four experiments were conducted that examine the affective and informational determinants of risk-preference behavior. In the initial two experiments, subjects classified according to their level of achievement needs expressed a preference among tasks varying in difficulty. In two of the experimental conditions, instructions, respectively, conveyed that performance at the task chosen should either maximize satisfaction or the information gained about one's ability and effort expenditure. It was found that the majority of all subjects preferred to undertake tasks of intermediate difficulty and that both positive affect and information gain were perceived to be optimal at or near the level of intermediate difficulty. Experiments III and IV investigated at what level of task difficulty individuals most desire information about their performance. Police trainees and high school students with disparate self-concepts of respective target shooting and high-jumping ability were able to receive limited but self-selected performance feedback at a series of achievement tasks that varied in difficulty. The data revealed that the tasks selected for feedback became objectively less difficult as the self-perception of ability decreased. In addition, the tasks chosen for feedback were near the intermediate subjective certainty of success level for all subjects. It was contended that the data contradict Atkinson's model of choice but support an attributional conception. The general issue of affective versus informational models of motivation was discussed.  相似文献

ABSTRACT While interest in philosophy and medicine has burgeoned in the past two decades, there remains a need for an analysis of the intellectual activity embodied in good medical practice. In this setting, ethical and scientific decision-making are complexly interrelated. The following paper, collaboratively written by physicians and philosophers, presents a view of applied (clinical) science and applied ethics. Making extensive use of illustrations drawn from routine case material, we seek to indicate a variety of philosophic issues to be found in daily practice, elucidate various levels of critical reasoning within the medical setting, and demonstrate a remarkable similarity between medical and ethical decision-making.  相似文献

It has been proposed that heterosexuals' negative attitudes toward homosexuals derives in part from perceptions that homosexuality threatens society's traditional sex role structure. This explanation suggests that persons who are more traditional in their sex role characteristics will hold more negative attitudes toward homosexuals. This hypothesis was tested using three aspects of sex role — sex role beliefs, sex role self-concept, and sex role behavior pattern — and four measures of attitudes toward homosexuals — attitudes toward male homosexuals, attitudes toward female homosexuals, personal responses to homosexual advances and feelings, and attitudes toward the social role of homosexuals. In general, for both female and male respondents, less negative attitudes were related to being older, being less conservative, and holding less traditional sex role beliefs. In addition, for women, less negativie attitudes were also associated with a more stereotypically masculine behavior pattern. The conceptual and methodological implications of these findings are discussed.I would like to thank Michael R. Stevenson for his helpful comments on an earlier version of this article.  相似文献

Availability of social support has been hypothesized to play a role in influencing adjustment to marital disruption either directly or by moderating the debilitating effects of stress. Yet previous research has not adequately conceptualized or measured the nature and availability of social support. In an effort to learn more about the structure and impact of social support as it relates to marital disruption, 50 newly separated men and women were interviewed at 2 months and again at 8 months after their separations. The structure of social support was found to include (a) several important sources of support, including family, friends, and the larger community; (b) an index of social activity; and (c) a sense of satisfaction with present marital status. Although the stress associated with separation was positively related to poorer adjustment, certain aspects of social support were found to moderate this relationship. This report is based, in part, on work supported by National Institute of Mental Health grant No. MH 26373 (Preventive Intervention for Newly Separated Persons), Bernard L. Bloom and William F. Hodges, co-principal investigators. We are pleased to acknowledge this support.  相似文献

The pastor is often in contact with the alcoholic and his or her family. Providing help to alcoholics and their families is a spiritual, humanistic, and therapeutic challenge. Recent developments have favored a family systems orientation to working with alcoholic families. This orientation acknowledges the family as contributor to maintaining alcoholic behavior and includes the family in treatment. Specific family systems concepts are discussed and how they relate to the dysfunctional unit which houses an alcoholic. Implications for pastors and specific role definitions are explored. Krebs' therapeutic model is expanded to: 1) evaluate, 2) support, 3) refer, and 4) support, as appropriate for the pastor working with alcoholics and their families.  相似文献

A patient suffering from a primary myocardiopathy is suddenly no longer able to recognize speech and environmental sounds, in spite of good peripheral hearing; he remains able to speak, read, and write. The C.T. scan shows lesions involving both supratemporal planes. The cortical sensory deficit documented by the absence of late acoustic evoked potentials leads to a diagnosis of cortical deafness rather than of auditory agnosia.  相似文献
