In some cases a person's religious beliefs can cause or exaccerbate emotional problems. Sometimes religious concepts can be used to ameliorate a client's problems. In dealing with Christian clients, the RET therapist can utilize the teachings and actions of Jesus in leading a client to recognize irrational beliefs. This paper illustrates and discusses rational teachings and actions of Jesus as regards four basic irrational beliefs and eleven underlying irrational beliefs.Sandra D.M. Warnock, M.A., served as a missionary to Hawaii with the Home Mission Board of the Southern Baptist Convention and as Minister of Outreach at Vinton Baptist Church, Vinton, Virginia. She was Senior Staff Clinician at Hollins Communications Research Institute in Hollins College, Virginia and is currently an adjunct lecturer in Psychology at Southside Virginia Community College in Keysville, Virginia.  相似文献

In an attempt to extend Bandura's theory of self-efficacy, we investigated the hypothesis that increases in self-efficacy, based on mastery experiences, would lead to improvements in mood and problem solving among dysphoric subjects.College students (N=79), classified as dysphoric or nondysphoric by the Beck Depression Inventory, were randomly assigned to anagram training groups that received bogus bar graphs suggesting either task ease or difficulty. Before and after training, subjects rated themselves on depressive affect (DACL) and self-efficacy. A difficult anagram task and a final DACL rating completed the procedure.Anagram training conditions did not lead to differential self-efficacy. However, multiple regression analyses showed that self-efficacy was related to depressive symptoms. Greater DACL decreases after training were seen in dysphoric subjects who reported higher posttraining self-efficacy. This improved mood is consistent with Bandura's theory. An unexpected finding among dysphoric subjects was that the higher their self-efficacy was, the lower was their final anagram performance. It appears that dysphoric/high self-efficacy subjects may have become more demoralized than dysphoric/low self-efficacy subjects when they encountered a need for much greater effort expenditure on the difficult anagram task.The findings suggest that skills training interventions which raise self-efficacy may be most effective in reducing depressive symptoms. The relevance of effort expenditure to the development of competine in depressed undiriduals appears to merit further investigation.where he served previously as Director of Clinical Psychology and as Chairperson of the Department of Psychology.Jeffrey Schwartz, Ph.D., a clinical psychologist, has been a staff member at the Cliffwood Mental Health Center in Englewood, New Jersey for the past five years.

HyperCard (Atkinson, 1987) is a new development environment for the Macintosh that shows promise for use in psychological research and testing. In this paper, we discuss the development of HyperCard stackware with which a block-design task similar to that of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) can be administered. The reliability and validity of the computerized block-design task was evaluated by administering both the computerized task and the WAIS-R subtest to college undergraduates. Results indicated that the computerized task’s reliability compared favorably with that of the WAIS-R subtest. Validity coefficients were equivocal; although an elapsed-time measure showed moderate correlation between the tasks, the numbers of designs correctly completed in each condition were not significantly correlated.  相似文献

Emerson (1988) provided a simple C-language timing routine for use with PC AT class machines. Unfortunately, this version of the timing routine makes use of nonstandard functions that are not available in all C-language packages. A modified version of this timing routine that does not make use of one of these nonstandard functions is provided. This version of TIMEX runs under the widely available Microsoft C 5.1. The need and availability of the remaining four nonstandard C functions is discussed. Constants needed to convert the timing routine units into seconds and milliseconds are also provided.  相似文献

A microcomputer running a spreadsheet program makes an excellent visual aid for demonstrating statistical concepts and procedures. Some advantages of this setup over traditional visual aids are described. Several statistical demonstrations that I have found to work well are presented.  相似文献

The purpose of the present paper is to describe and compare some inexpensive software packages that calculate a variety of statistics on microcomputers running MS-DOS. For each package, hardware requirements, program capabilities, limitations, accuracy, error handling, and other features are considered.  相似文献

Researchers interested in studying discrimination learning in primates have typically utilized variations in the Wisconsin General Test Apparatus (WGTA). In the present experiment, a new testing apparatus for the study of primate learning is proposed. In the video-task paradigm, rhesus monkeys (Macaca mulatta) respond to computer-generated stimuli by manipulating a joystick. Using this apparatus, discrimination learning-set data for 2 monkeys were obtained. Performance on Trial 2 exceeded 80% within 200 discrimination learning problems. These data illustrate the utility of the video-task paradigm in comparative research. Additionally, the efficient learning and rich data that were characteristic of this study suggest several advantages of the present testing paradigm over traditional WGTA testing.  相似文献

Using bar code technology to automate data collection provides a rapid and reliable alternative to paper-and-pencil tracking or keyboard entry into pocket or laptop computer. An array of bar code symbols is printed on a data menu, with a unique symbol corresponding to each possible observation. Bar code symbols are scanned using hand-held readers, which record the event, log the observation time, and store data for transfer to a personal computer. Advantages of the bar code monitoring system include: (1) ease of use by staff with minimal technical training, (2) reduced data entry errors and increased entry speed, (3) reliable portable operation, and (4) low-cost hardware. While the bar code system described here is used for behavioral monitoring in a residential treatment setting for the developmentally disabled, with minimal modification this system can be adapted for use in a wide variety of research and clinical applications.  相似文献

In a previous essay I criticized Engelhardt's libertarian conception of justice, which grounds the view that society's obligation to assure access to adequate health care for all is a matter of beneficence [1]. Beneficence fails to capture the moral stringency associated with many claims for access to health care. In the present paper I argue that these claims are really matters of justice proper, where justice is conceived along moderate egalitarian lines, such as those suggested by Rawls and Daniels, rather than strong egalitarian lines. Further, given the empirical complexity associated with the distribution of contemporary health care, I argue that what we really need to address the relevant policy issues adequately is a theory of health care justice, as opposed to an all-purpose conception of justice. Daniels has made an important start toward that goal, though there are some large policy areas which I discuss that his account of health care justice does not really speak to. Finally, practical matters of health care justice really need to be addressed in a ‘non-ideal’ mode, a framework in which philosophers have done little.  相似文献
