A poignant feature of many near-death experiences is a visionary encounter with deceased loved ones. Over the centuries, researchers have sought safe ways to replicate near-death and related experiences, hoping to induce the powerful aftereffects of these events. The ancient Greeks contructed psychomanteums, or oracles of the dead, where seekers could consult spirits of the deceased. I describe a modern attempt to recreate the psychomanteum. Like near-death experiences, visionary encounters in this modern psychomanteum are experienced as real and not as hallucinatory, and have profound personal aftereffects. This novel experimental technique may permit the scientific study of phenomena that previously occurred only spontaneously and under uncontrolled circumstances. 相似文献

This study investigated the relationship between intergenerational family relationships and Frankl's concept of meaning in life. Intergenerational family relationships were measured by the Personal Authority in the Family System Questionnaire (PAFS-QE) by Bray, Williamson, and Malone. The meaning in life variables were measured by the Life Attitude Profile-Revised (LAP-R) by Reker. This quantitative study, using the BMDP Statistical Package (Dixon, 1990), correlated the scores on various subscales from both instruments, resulting in seven statistically significant relationships. The findings, although modest, suggest the existence of a relationship between these two theoretical areas.This article is based in part on the first author's doctoral dissertation at Texas Woman's University.A copy of the PAFS-Q may be obtained from: James H.

The primary care setting is seen by many to be at the forefront of the attempt to encourage people to follow healthier diets. Conducted in a single practice, the present study firstly considered the effectiveness of three ‘healthy eating’ clinics for patients found to have elevated cholesterol levels at screening. Through the use of a randomised trial, these patients received either basic dietay information or were invited back more frequently and requested to complete food diaries, half of which were then analysed through a computer program. At one year follow up the three programmes were found to have produced a 6.7% reduction in cholesterol levels. However, no differences were found between the three programmes. The study secondly examined a range of health belieji, based on the health belief model, as predictors of reductions in cholesterol levels. These were generally found to be poor predictors, with only the belief that one's diet is related to the chances of developing a number of major conditions and the perception of bam'ers dealing with confidence predicting these reductions. Finally, the case for incorporating self-efficacy beliefs into the healh belief model is outlined and the need for health counsellors to tailor their messages to the pre-existing beliefi and behaviours of patients is highlighted. 相似文献

This exploratory study sought to determine whether selected religion-related factors differentiated between 86 patients with
obsessive compulsive disorder (OCD), 73 patients with panic disorder, and 292 patients with other psychiatric (non-anxiety)
disorders. A standard history questionnaire was used to obtain information from patients concerning religion of origin, involvement
in religious activities, religious conflict, and perceived religiousness of parents. It was found that the percentage of patients
who reported experiencing religious conflict was significantly higher for the OCD group than for the other two groups. Other
findings suggested associations between Catholicism and OCD and between Protestantism and panic disorder, but further research
is needed to clarify these relationships.
This article is based on a paper presented at the 98th annual convention of the American Psychological Association, Boston,
August 1990. 相似文献

Neural networks can be used as a tool in the explanation of neuropsychological data. Using the Hebbian Learning Rule and other such principles as competition and modifiable interlevel feedback, researchers have successfully modeled a widely used neuropsychological test, the Wisconsin Card Sorting Test. One of these models is reviewed here and extended to a qualitative analysis of how verbal fluency might be modeled, which demonstrates the importance of accounting for the attentional components of both tests. Difficulties remain in programming sequential cognitive processes within a parallel distributed processing (PDP) framework and integrating exceedingly complex neuropsychological tests such as Proverbs. PDP neural network methodology offers neuropsychologists co-validation procedures within narrowly defined areas of reliability and validity. 相似文献

Recently, debate about the distribution of scarce organs for transplantation has focused on whether patients should have the right to place themselves on waiting lists at several transplant centers, thereby gaining an advantage over other potential recipients. This article explores the social and ethical issues raised by multiple listing, contrasting policies adopted at the national level with those implemented in New York State. It concludes by examining the implications of the debate for broader questions about entitlement and access to health care. 相似文献

With increasing momentum for health care reform, attention is shifting to finance reform that will provide for direct methods for controlling health care spending. This article outlines the two principal paths to direct cost control and outlines a national plan that retains our multiple sources of payment, yet also contains a powerful direct cost control technique: a single fund to finance all health care. 相似文献

Quantification of a chaotic system can be made by calculating the correlation dimension (D2) of the data that the system generates (Packard et al., 1980). The D2 algorithm, however, requires stationarity of the generator, a feature that biological data rarely reflect (Mayer-Kress et al., 1988). So we developed the "point correlation dimension" (PD2), an algorithm that accurately tracks D2 in linked data of different dimensions (Carpeggiani et al., 1991). We now present a mathematical argument that, for stationary data, individual PD2s converge to D2 and we demonstrate that the algorithm rejects contributions made by bursts of noise. Data were obtained from the surface of the olfactory bulb of the conscious rabbit (64 electrodes, 640 Hz each, 1.3 sec epochs) before and after presentation of a novel or habituated odor. D2 could be calculated in only 1 of 10 novel-odor trials, whereas PD2 could be calculated in all. Both algorithms indicated that a novel odor evokes a spatially uniform dimensional increase. The PD2 uniquely exhibited the dimensional decreases that occur during inspiration and the gradients of mean dimension present during the nonstimulated control state. These control gradients remained unchanged without odor experience, but showed spatially specific PD2 increases following odor habituation. It is interpreted that, 1) the PD2 is sensitive, accurate, and appropriate for dimensional assessment of biological data, 2) that during analysis of unfamiliar information a single global process is transiently evoked in the neuropil, and 3) after experience multiple spatially specific processes tonically map the sites of learning. 相似文献

Two dogs received a single paired classical conditioning trial, with tone CS and 12 mA shock US. Both dogs then showed a conditioned blood pressure increase in response to the nonreinforced CS, which extinguished with additional nonreinforced presentations. The CR showed spontaneous recovery four days later, but reextinguished with additional nonreinforced presentations. The results were interpreted as not supporting Eysenck's theory of "incubation" following one-trial aversive conditioning. 相似文献
