Low levels of proactivity are characteristic of individuals with depression. Two studies were conducted to compare the relative effects of abstract versus concrete processing on proactivity in high dysphoric individuals. In Study 1, participants read information about an upcoming research study and were then randomly allocated to a writing task that induced them to think about participating in that study in either an abstract (e.g., Why you would participate in the study?; n = 25) or concrete (e.g., How you will participate in the study?; n = 25) way. Participants were then asked to indicate whether they would sign up to the study. As expected, more participants indicated that they would take part in the study in the concrete condition (76%) than in the abstract condition (36%). In Study 2, high dysphoric participants were asked to identify their ideal part-time job and were then randomly allocated to a writing task that induced them to think about applying for the job in an abstract (n = 26) or concrete (n = 25) way. There was no difference between conditions in self-reported intentions of proactivity. However, significantly more participants in the concrete condition opted to look at an employment assistance website and returned to the lab to collect a job application package. Overall, these findings suggest that abstract processing could contribute to low levels of proactivity in depression, and that facilitating the use of concrete processing could help to alleviate this problem. Our results also point to the need for greater conceptual clarification of the distinction between concrete processing about proactive behavior and implementation intentions (identifying specific steps for completing an action/goal).  相似文献

Research suggesting both a superiority of frequencies over single‐event probabilities and of smaller reference classes over very large reference classes have utilized tasks that vary in computational complexity. The present research sought to simply and directly evaluate if—apart from simplifying statistical inference tasks—frequencies and small reference classes are clearer than other formats. After eliminating possible computational confounds, simple frequencies (based on small reference classes, e.g. 1/3) and to some extent relative frequencies (percentages, e.g. 33%) were perceived as clearer than absolute frequencies (based on very large reference classes, e.g. 90 million Americans) and single‐event probabilities (e.g. 0.33). Concurrently, these different formats were evaluated in terms of their relative influence. Absolute frequencies were relatively more persuasive for smaller magnitudes (e.g. 2.7 million) but less persuasive for larger magnitudes (e.g. 267 million), as compared to analogous presentations. Single‐event probabilities were judged to minimize the significance of information. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

克隆人的出现是后生命科学时代开始的标志;原有的高新生命科学技术发展时期是科学过渡带;人类基因组计划、克隆人与胚胎干细胞研究是后生命科学事件。传统伦理学和神学伦理学在后生命科学时代理论资源桔竭,已达边界;我们“只有同意识形态断裂,彻底改变其结构,才能有真正的科学”;我们必须一边从传统中寻求辩护、一边解放伦理学和神学(经典理论后现代化)。清除障碍,获得解放。  相似文献

Evidence suggests that cancer risk assessment may be associated with increased psychological distress. This exploratory study assessed the necessity and acceptability of incorporating psychological counseling into routine clinic procedures at a cancer risk program. Following a visit to a university-based cancer risk clinic, patients (N = 102) completed an anonymous self-report instrument. Participants reported experiencing current stress and anxiety (41%), depression (29%), and suicidal ideation (2%). Patients with a history of cancer were more likely to be experiencing current emotional difficulties. Sixty-nine percent of the participants found the visit with the psychological counselor to be helpful, while 41% of the participants reported interest in follow-up psychological services. Interest in receiving future psychological services was positively correlated with levels of anxiety, depression, and cancer worry. This pilot study demonstrates the acceptability and potential role for psychological counselors in increasing adjustment in high-risk patients undergoing genetic counseling for inherited cancers.  相似文献

Solving complex socio-technical problems, this paper claims, involves diverse knowledges (cognitive diversity), competing interests (social diversity), and pragmatism. To explain this view, this paper first explores two different cases: Canadian pulp and paper mill pollution and siting nuclear reactors in seismically sensitive areas of California. Solving such socio-technically complex problems involves cognitive diversity as well as social diversity and pragmatism. Cognitive diversity requires one to not only recognize relevant knowledges but also to assess their validity. Finally, it is suggested, integrating the resultant set of diverse relevant and valid knowledges determines the parameters of the solution space for the problem.

Part of the National Placebo Initiative in Canada included public consultations, based on the belief that the views of the public should inform Canadian policy development on what constitutes appropriate placebo use. Public consultations took place nationally in 2003. A deliberative dialogue approach was used, or a structured discussion format designed to facilitate the consideration of complex issues and build consensus. The placebo debate was characterized as having 3 distinct approaches and each were explored. The first approach “Maximize Patient Protection” identified the need for experts to determine appropriate placebo use and that placebos should only be allowed under very restricted conditions. The second approach “Maximize Medical Knowledge” identified that placebos give essential information about the safety and efficacy of new drugs, and are appropriate when the rights, safety and well-being of research participants are ensured. The third approach “Maximize Patient Autonomy” identified that the current system of regulating placebo use is paternalistic and that patients should be able to define what is in their best interests and have more leeway to determine for themselves if they wish to participate in a placebo-controlled trial. Advantages and disadvantages of each approach were considered and feedback on what constitutes appropriate placebo use was sought. The major findings were that: PCTs were considered a valuable and acceptable part of advancing medical knowledge; research using placebos must be valid and justifiable; a patient-centred approach needs to be fostered; patient autonomy (choice) should be a first consideration and take clear precedence in trials of low to medium risk; patient protection (or health) may need to “trump” patient autonomy at higher levels of risk and/or patient vulnerability; placebos are not a violation of the duty of care as duty of care is best met by identifying a choice for patients, whenever a choice is available. These consultations clearly were not designed to produce conclusive evidence, but rather to provide some useful insights into what the public may think about placebo use; additional studies are indicated. Funding for the public consultations was provided by Health Canada and the Canadian Institutes of Health Research. An earlier version of this paper was presented at an international conference, “Placebo: Its Action and Place in Health Research Today,” held in Warsaw, Poland on 12–13 April, 2003.  相似文献

Arguments in favor of legalized assisted suicide often center on issues of personal privacy and freedom of choice over one's body. Many disability advocates assert, however, that autonomy arguments neglect the complex sociopolitical determinants of despair for people with disabilities. Specifically, they argue that social approval of suicide for individuals with irreversible conditions is discriminatory and that relaxing restrictions on assisted suicide would jeopardize, not advance, the freedom of persons with disabilities to direct the lives they choose. This paper examines the idea promoted by some proponents of assisted suicide that it is reasonable to be depressed about one's diminished quality of life in cases of irreversible illness or disability and, therefore, such depression should not call into question the individual's competence to request assistance in dying. The concept of rational depression is defined and examined in the context of: four real-life cases involving individuals with disabilities who requested assistance in dying; a set of criteria commonly applied to decision-making to determine rationality; and research bearing on the emotional status of people with disabilities. It is concluded that although disability is associated with particular socially mediated stressors, there is no theoretical or empirical evidence to indicate that depression and its role in the right to die is dynamically different, more natural, or more reasonable for disabled people than for non-disabled people.  相似文献
