Explanation, imagination, and confidence in judgment.   总被引:2,自引:0,他引:2  
This article concerns a class of experimental manipulations that require people to generate explanations or imagine scenarios. A review of studies using such manipulations indicates that people who explain or imagine a possibility then express greater confidence in the truth of that possibility. It is argued that this effect results from the approach people take in the explanation or imagination task: They temporarily assume that the hypothesis is true and assess how plausibly it can account for the relevant evidence. From this view, any task that requires that a hypothesis be treated as if it were true is sufficient to increase confidence in the truth of that hypothesis. Such tasks cause increased confidence in the hypothesis at the expense of viable alternatives because of changes in problem representation, evidence evaluation, and information search that take place when the hypothesis is temporarily treated as if it were true.  相似文献

Token reinforcement, choice, and self-control in pigeons.   总被引:9,自引:9,他引:0       下载免费PDF全文
Pigeons were exposed to self-control procedures that involved illumination of light-emitting diodes (LEDs) as a form of token reinforcement. In a discrete-trials arrangement, subjects chose between one and three LEDs; each LED was exchangeable for 2-s access to food during distinct posttrial exchange periods. In Experiment 1, subjects generally preferred the immediate presentation of a single LED over the delayed presentation of three LEDs, but differences in the delay to the exchange period between the two options prevented a clear assessment of the relative influence of LED delay and exchange-period delay as determinants of choice. In Experiment 2, in which delays to the exchange period from either alternative were equal in most conditions, all subjects preferred the delayed three LEDs more often than in Experiment-1. In Experiment 3, subjects preferred the option that resulted in a greater amount of food more often if the choices also produced LEDs than if they did not. In Experiment 4, preference for the delayed three LEDs was obtained when delays to the exchange period were equal, but reversed in favor of an immediate single LED when the latter choice also resulted in quicker access to exchange periods. The overall pattern of results suggests that (a) delay to the exchange period is a more critical determinant of choice than is delay to token presentation; (b) tokens may function as conditioned reinforcers, although their discriminative properties may be responsible for the self-control that occurs under token reinforcer arrangements; and (c) previously reported differences in the self-control choices of humans and pigeons may have resulted at least in part from the procedural conventions of using token reinforcers with human subjects and food reinforcers with pigeon subjects.  相似文献

The Christian conviction about Divine Providence encourages a novel account of the moral content of health and authority in the health care context. While health can be understood as the disposition of a living body to be able to proceed in the world well, as a species of freedom it is informed by the particular projects and concerns that Christians hold deepest. This is due to the fact that health acquires content, and thus becomes desirable as a particular type of good, only in relation to judgments about the good life. Aquinas' reflections concerning the good of health and its partial slavery to fortune reveal a Christian past that dwelt on the intrinsic and instrumental good of health. A rich Christian tradition in which health as intrinsically good, a good of the body, is ordained to the interests of right Christian virtue. Each of these factors affects the character of the health to be pursued and the authority of the physician as determining the ends and means of medicine.  相似文献

Associations between overweight, sexual assault history, and suicide attempts were examined among 31,540 adolescents from the combined 2009 and 2011 nationally representative Youth Risk Behavior Surveys samples. These variables have not previously been studied concurrently. It was hypothesized that overweight and sexual assault, together, would interact and result in increased suicide attempts. Findings across analyses included (a) no significant associations between sexual assault and overweight in females or males (p = .65 and p = .90, respectively), (b) statistically significant associations between female (but not male) overweight status and suicide attempts (= .001), (c) a strong association between sexual assault and suicide risk in males (p < .001) and females (p < .001), and (d) an elevated risk for suicide in overweight males with co‐occurring sexual assault, with over 33% of males with such histories attempting suicide. Preliminary findings have powerful implications for research and secondary prevention.  相似文献

The need for a coordinated national policy on family support in the home is discussed. First, the history of home visiting programs is reviewed. Then, recommendations for practice, training, and research in family support programs are presented. A discussion of the impact of new federal initiatives on family support programs and research demonstration efforts follows.  相似文献
