Understanding the mental processes involved in suffering has always been the best basis for communication between patients and caretakers. In this paper we are concerned first with acknowledgment of the existence, generally unknown, and the effects, generally unrecognized, of the hypnotic processes that occur in many forms of suffering, and second with developing our thesis that the understanding and use of hypnotic principles can greatly enrich the chaplain's capacity to alleviate suffering. In this brief presentation we will confine our discussion to the teaching of hypnosis as a virtual necessity in modern clinical training for chaplains. Comments and considerations will precede and follow an outline of the course presently offered at Lenox Hill Hospital [but we cannot here attempt to discuss or explain the fundamentals of hypnotic process or any other aspects of the course content itself]. A basic bibliography is appended for those who wish to know more about hypnosis itself.  相似文献

In this contribution we show how neuroimaging methods can augment behavioural methods to discover processing stages. Event Related Brain Potentials (ERPs), Brain Electrical Source Analysis (BESA) and regional changes in cerebral blood flow (rCBF) do not necessarily require behavioural responses. With the aid of rCBF we are able to discover several cortical and subcortical brain systems (processors) active in selective attention and memory search tasks. BESA describes cortical activity with high temporal resolution in terms of a limited number of neural generators within these brain systems. The combination of behavioural methods and neuroimaging provides a picture of the functional architecture of the brain. The review is organized around three processors: the Visual, Cognitive and Manual Motor Processors.  相似文献

Abstract. Science and revelation have been presented as two books with the same “author,” their reconciliation being called “concordism.” Teilhard opposed concordism, insisting that supposed “revelations” be treated as scientific hypotheses to be verified or not in experience. Applying his criterion for truth (Does it bring “coherence and fecundity” to the phenomena?) to Christian revelation, he told of finding “an explosion of dazzling flashes.” So Teilhard spoke of the hypothesis as the supreme spiritual act wherein the dust of experience takes on form and is kindled at the fire of knowledge.  相似文献

Abstract. Theology and ethics intersect with sciences at different points depending upon whether the scholars involved are interested in, for example, general epistemological issues or practical moral judgments. The intersection affects theology and ethics in different ways, depending upon various commitments or resistances on the part of theologians. The author surveys his own writings to show how openness to the sciences has had an impact on various phases of his work and what issues remain somewhat unresolved.  相似文献

Recent legislative and regulatory developments have focused attention on older adults' capacity for involvement in health care decision-making. The Omnibus Budget Reconciliation Act of 1987 (OBRA 87) focused attention on the rights of nursing home residents to be involved in health care decision-making to the fullest extent possible. This article uses data from the 1987 National Medical Expenditure Survey (NMES) to examine rates of incapacity for health care decision-making among nursing home residents. Elements of the Oklahoma statute were used to operationalize decision-making incapacity: disability or disorder, difficulty in decision-making or communicating decisions, and functional disability. Fifty-three percent of nursing home residents had a combination of either physical or mental impairment and an impairment in either self-care or money management. The discussion focuses on the policy and practice implications of significant rates of incapacity among nursing home residents.  相似文献

The present study examined the effect of sex similarity on recruiters' evaluations of actual applicants in campus interviews and tested whether perceived similarity and interpersonal attraction mediated this effect. Structural equation modeling was performed on data from 476 campus interviews. The results revealed complex effects of sex similarity on recruiters' decision processes. Perceived similarity and interpersonal attraction mediated the effect of sex similarity on female recruiters' assessments of applicants' qualifications. Unexpectedly, female recruiters saw male applicants as more similar to themselves and more qualified than female applicants. For male recruiters, interview outcomes were not affected by sex similarity. Social identity theory, which suggests that the status associated with demographic characteristics may influence the nature of demographic similarity effects, provides a possible explanation for the findings.  相似文献

Two families, in which the children had been placed in foster care due to abuse and neglect by parents who had disabilities, were studied. In the first case, the mother was instructed in skills that our assessment suggested were important for her child's survival. The mother readily acquired and applied these skills, a fact reflected both in changes in her behavior and in changes in the child's well-being. In the second case, the parent's incremental resumption of child custody was made contingent upon completion of relevant parenting tasks. Initially, improvements in the completion of such tasks were evident, but over time and with the onset of militating factors, no further progress was made and all parental rights were terminated. The implications of these cases for behavior analysis and the effort to reunite and preserve families are discussed.  相似文献

ABSTRACT Participants performed a cognitive task under evaluative, self-awareness, and neutral conditions, Task performance was determined jointly by trait test anxiety and situational factors. Test anxiety led to poorer performance in both evaluative and self-awareness situations, relative to the neutral situation. We examined the cognitive activity variables that might mediate the effects of test anxiety and situational variables on performance, and identified a significant cognitive mediator of the main effect of test anxiety, but not for the Test Anxiety x Situation interaction effect. Therefore, the current experiment offered some support for Sarason's (1980) cognitive interference theory, as well as integrating test anxiety and self-awareness research.  相似文献

Behavioral momentum theory relates resistance to change of responding in a multiple-schedule component to the total reinforcement obtained in that component, regardless of how the reinforcers are produced. Four pigeons responded in a series of multiple-schedule conditions in which a variable-interval 40-s schedule arranged reinforcers for pecking in one component and a variable-interval 360-s schedule arranged them in the other. In addition, responses on a second key were reinforced according to variable-interval schedules that were equal in the two components. In different parts of the experiment, responding was disrupted by changing the rate of reinforcement on the second key or by delivering response-independent food during a blackout separating the two components. Consistent with momentum theory, responding on the first key in Part 1 changed more in the component with the lower reinforcement total when it was disrupted by changes in the rate of reinforcement on the second key. However, responding on the second key changed more in the component with the higher reinforcement total. In Parts 2 and 3, responding was disrupted with free food presented during intercomponent blackouts, with extinction (Part 2) or variable-interval 80-s reinforcement (Part 3) arranged on the second key. Here, resistance to change was greater for the component with greater overall reinforcement. Failures of momentum theory to predict short-term differences in resistance to change occurred with disruptors that caused greater change between steady states for the richer component. Consistency of effects across disruptors may yet be found if short-term effects of disruptors are assessed relative to the extent of change observed after prolonged exposure.  相似文献
