The negative-tilt preparation that has been reported since the late seventies is a specific form of Pavlovian conditioning that is of scientific interest and has potential applications. In this paper I reflect on the usefulness, to the development of this preparation, of two approaches to Pavlovian conditioning. One approach is the older S-R learning, stimulus-substitution paradigm exemplified by learning texts of the sixties. The other is the modern, Tolman-like view, according to which the phenomenon of Pavlovian conditioning is “now described as the learning of relations among events so as to allow the organism to represent its environment.” The three assumptions encapsulated by this approach are: (a) that only CS-US contingency relations are learned; (b) that teleological modes of explanations are adequate; (c) that the representational theory of knowledge is sound. Concerning Pavlovian conditioning in general, questions been raised in the literature for all three assumptions; they have not been adequately answered. Regarding the specific problem of developing the human Pavlovian heart-ratedecelerative conditioning with negative tilt as the US, I suggest that the cognitive approach has been much less helpful than the older, S-R, stimulus-substitution paradigm. Nevertheless, other literature clearly indicates that the cognitive, S-S approach has generated considerable interest and research, especially in preparations like the conditioned emotional response (CER), which are CS-IR ones in the sense that the effects on the CR are assessed indirectly through measuring an indicator or instrumental response (IR). Finally, even in CS-CR preparations like human GSR conditioning, it is important to study the cognitive, S-S learning process through using such dependent variables as continuously assessed subjective CS-US contingency. 相似文献

This article provides a critical review of two major types of expert evidence: (a) clinical assessments, and (b) generalizations drawn from psychological research. Strong arguments both for and against both types of testimony have been offered by legal experts and psychologists. These arguments are evaluated and the conclusion is drawn that there are two fundamental problems for psychologists in the role of expert. First, the types of assessments clinicians are asked to make (e.g., concerning the accused's mental state at the time of committing the offense) may exceed the capacity of the discipline; such assessments are problematic. Second, the research foundation that psychologists employ in court does not always apply to the court situation in the way experts imply; the application of laboratory research findings to real world contexts is sometimes premature. The article concludes with an admonition that psychologists should adopt a more conservative response to requests to provide expert evidence. 相似文献

This article describes a FORTRAN 77 subroutine which manipulates the audio hardware facilities on the Amiga microcomputer.
The subroutine may be instructed to produce either tones or musical notes on any combination of four independent channels.
Frequency, volume, and type of waveform are passed to the subroutine as parameters. Some limitations in relation to sound
production on the Amiga are discussed. 相似文献

Brief group psychotherapy as a method of treating psychological aftereffects of retirement is still in its infancy. It is therefore still possible to outline the whole field in overview. This paper examines the dynamics of aging and the relevant literature, discusses the conceptual issues involved, and describes techniques employed with this specific population. The typical cluster of complaints is portrayed, the psychological stressors associated with retirement are analyzed, and the various group-therapeutic modalities developed to counteract them are described. Furthermore, the rationale, process and characteristics of short-term group psychotherapy in the treatment of adjustment difficulties to retirement are reviewed. The clinical application of this approach, the therapist's particular roles and the therapeutic impact of this method are delineated.He would like to thank his co-therapist, Mrs. Sophie Bielawski, Reg. O.T., for her support and helpful observations and Drs. J. Regan and E. Sunday for their advice on methodolody. 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.
