Cognitive change processes in psychotherapy   总被引:1,自引:0,他引:1  
Several types of cognitive-behavioral therapy are now practiced that use different sets of theoretical concepts and propose different kinds of change mechanisms. None, however, is directly grounded in experimental research in cognitive and social psychology, and few address basic issues such as the relevance of conscious versus nonconscious cognitive processes and the validity of the self-report data on which therapy depends. Put forward in this article is a model that describes the conscious and nonconscious processing of emotional stimuli and distinguishes between knowledge that is verbally accessible and knowledge that can only be recovered by exposure to situational cues. Also proposed are three mechanisms of cognitive change that involve altering verbally accessible knowledge, the accessibility of nonconscious situational memories, and self-regulatory strategies. These mechanisms are related to the current practices of behavioral and cognitive-behavioral therapists.  相似文献

Examines the connections among believing, saying, and expressing in situations where the sentence used is a declarative sentence containing at least one proper name. Proposes a new way of understanding these connections. Develops an argument for the thesis that, although we typically believe the singular propositions expressed by our uses of name sentences, we rarely use such sentences because we believe those propositions.  相似文献

A model of telescoping is proposed that assumes no systematic errors in dating. Rather, the overestimation of recent occurrences of events is based on the combination of three factors: (1) Retention is greater for recent events; (2) errors in dating, though unbiased, increase linearly with the time since the dated event; and (3) intrusions often occur from events outside the period being asked about, but such intrusions do not come from events that have not yet occurred. In Experiment 1, we found that recall for colloquia fell markedly over a 2-year interval, the magnitude of errors in psychologists' dating of the colloquia increased at a rate of .4 days per day of delay, and the direction of the dating error was toward the middle of the interval. In Experiment 2, the model used the retention function and dating errors from the first study to predict the distribution of the actual dates of colloquia recalled as being within a 5-month period. In Experiment 3, the findings of the first study were replicated with colloquia given by, instead of for, the subjects.  相似文献

Explanations of context effects in the Reicher-Wheeler task and the letter-identification task appeal to word-based processing, yet these tasks provide no explicit measure of word processing. An experiment is reported which was designed to investigate the use of transfer in the word-identification task as a measure of word-based processing in letter-identification tasks. It was found that encoding manipulations that determined whether a word-superiority effect was or was not found in a letter-identification task (e.g., Thompson & Massaro, 1973) also determined whether transfer was or was not found in a subsequent word-identification task. The results of the experiment are discussed in terms of the utility of using transfer experiments as converging evidence about the presence and/or absence of processes that cannot be directly measured in other experimental paradigms.  相似文献

Two alternative hypotheses were considered concerning the process of prolonged search for an uncommon word in response to hearing its definition. One alternative is that a conscious retrieval effort brings the target progressively closer to threshold. The second is that the retrieval process is a random neural exploration outside of conscious control. A tachistoscopic probe was devised to compare word recognition thresholds after 10 sec versus 30 sec of presumed search time. Results failed to show a difference between the two delay conditions and were interpreted as inconsistent with the first alternative but consistent with the second.  相似文献

A componential model for mental addition   总被引:2,自引:0,他引:2  
A componential model capable of representing simple and complex forms of mental addition was proposed and then tested by using chronometric techniques. A sample of 23 undergraduate students responded to 800 addition problems in a true-false reaction time paradigm. The 800 problems comprised 200 problems of each of four types: two single-digit addends, one single- and one double-digit addend, two double-digit addends, and three single-digit addends. The results revealed that the columnwise product of addends, a structural variable consistent with a memory network retrieval process, was the best predictor of mental addition for each of the four types of problem. Importantly, the componential model allowed estimation of effects of several other structural variables, e.g., carrying to the next column and speed of encoding of digits. High levels of explained variance verified the power of the model to represent the reaction time data, and the stability of estimates across types of problem implied consistent component use by subjects. Implications for research on mental addition are discussed.  相似文献

Young and older adults studied lists of words under both standard and optimal study conditions for subsequent free recall. Under optimal conditions, the participants studied each word for as long as they wished, were allowed to take notes, and were encouraged to actively use whatever strategies they thought would maximize recall. Both age groups recalled more words under optimal study conditions than under standard conditions, but the improvement was greater for the young adults. This increase in the age-related recall deficit was not due to differences in study time. The results suggest that standard laboratory memory tasks do not overestimate the memory deficits of older adults because of a failure to provide either optimal learning conditions or sufficient study time.  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 paper addresses the use of the weekly written summary with patients in group psychotherapy. In an effort to stimulate group process and effect cotherapist communication, the authors instituted this group recording in an ongoing psychodynamically oriented mixed adult group. While the utilization of this device did, in fact, stimulate the group process and became an important part of the group's life, the therapists additionally saw significant effects upon their working alliance. These included increased focused dialogue upon group dynamics, more purposeful planning for group interventions, and heightened awareness of the significance of interventions in the group.Ms. Bosman-Clark is formerly Clinical Instructor, Department of Psychiatry, Baylor College of Medicine.  相似文献

The failure of controlled experimental research on therapy out-come to produce findings of clinical as well as statistical significance seems at least partly due to irrational, perfectionistic, beliefs about how research can be used to infer causes of therapeutic change. Irrational beliefs about controlled experimental designs and about incomplete sampling, in particular, appear to prevent appropriate consideration of probatively valuable quasi-experimental research. Models of more rational alternatives are identified, and an example of the functional advantages of adopting these rational beliefs is explicated. The example demonstrates that single-shot pre-post survey data from self-selected catch-as-catch-can samples can permit legitimate, but not absolutely certain, conclusions about the efficacy and efficiency of RET.Albert Ellis, Ph.D. is executive director of the Institute for Rational-Emotive Therapy in New York City.  相似文献
