Evidence hierarchies are widely used to assess evidence in systematic reviews of medical studies. I give several arguments against the use of evidence hierarchies. The problems with evidence hierarchies are numerous, and include methodological shortcomings, philosophical problems, and formal constraints. I argue that medical science should not employ evidence hierarchies, including even the latest and most-sophisticated of such hierarchies. 相似文献

When humans are asked to judge the value of a set of objects of excellent quality, they often give this set higher value than those same objects with the addition of some of lesser quality. This is an example of the affect heuristic, often referred to as the less-is-more effect. Monkeys and dogs, too, have shown this suboptimal effect. But in the present experiments, normally hungry pigeons chose optimally: a preferred food plus a less--preferred food over a more-preferred food alone. In Experiment 2, however, pigeons on a less-restricted diet showed the suboptimal less-is-more effect. Choice on control trials indicated that the effect did not result from the novelty of two food items versus one. The effect in the less-food-restricted pigeons appears to result from the devaluation of the combination of the food items by the presence of the less-preferred food item. The reversal of the effect under greater food restriction may occur because, as motivation increases, the value of the less-preferred food increases faster than the value of the more-preferred food, thus decreasing the difference in value between the two foods. 相似文献

Aging is accompanied by an increase in false alarms on recognition tasks, and these false alarms increase with repetition in older people (but not in young people). Traditionally, this increase was thought to be due to a greater use of familiarity in older people, but it was recently pointed out that false alarms also have a clear recollection component in these people. The main objective of our study is to analyze whether the expected increase in the rate of false alarms in older people due to stimulus repetition is produced by an inadequate use of familiarity, recollection, or both processes. To do so, we carried out an associative recognition experiment using pairs of words and pairs of images (faces associated with everyday contexts), in which we analyzed whether the repetition of some of the pairs increases the rate of false alarms in older people (compared to what was found in a sample of young people), and whether this increase is due to familiarity or recollection (using a remember‐know paradigm). Our results show that the increase in false alarms in older people due to repetition is produced by false recollection, calling into question both dual and single‐process models of recognition. Also, older people falsely recollect details of never studied stimuli, a clear case of perceptual illusions. These results are better explained in terms of source‐monitoring errors, mediated by people's retrieval expectations. 相似文献

This article explores how flow theory and the serious leisure perspective (SLP) can be integrated into mental health counseling. Although different counseling models have acknowledged the role of leisure in the counseling process, leisure is largely an unknown and superficial concept in the mental health counseling literature. Four broad-based pragmatic ideas regarding how flow theory and the SLP can be integrated into the counseling process include mental health counselors (1) understanding the concepts of serious leisure, casual leisure, project-based leisure, flow (enjoyment), and hedonistic pleasure; (2) becoming aware of various assessment instruments that measure flow and serious leisure; (3) using the provision characteristics of entering flow into the counseling process; and (4) empowering clients to becoming community change agents through serious leisure pursuit, resulting in flow experiences. 相似文献

This article argues that we can improve the way we teach early modern political philosophy if we introduce students to alternative views about the development of the state. First, it summarizes the work of contemporary philosophers and historians who are critical of the modern state. Second, it points out ways in which early social contract theorists take the state for granted. Third, it argues that alternative views about the development of the state can help students take a more critical perspective on standard works of early modern political philosophy. Fourth, it argues that these alternative views will help students better understand dissenting voices in early modern political philosophy. 相似文献
