A revised version of the Rescorla-Wagner (1972) mathematical model is presented. A metatheoretical assumption of an attentional process, the added revision, is conceived as an independent α-salience growth factor determining both rate of association and performance. Conditioned stimulus-unconditioned stimulus (CS-US) correlation, and CS-US interval (two primary conditioning parameters) are incorporated in the mathematical model as α-salience growth rate and as α-salience and association asymptote factors, respectively. In this manner, the long-standing issue of necessary and sufficient factors in classical conditioning is resolved. An empirical assessment of the model’s parameters has been included. 相似文献

The influence of alcohol and loud music on analytic versus holistic processing was examined in classification, concept learning, and embedded figures tasks. In the classification task, loud music reduced analytic responding by individuals who had consumed alcohol and increased analytic responding by individuals who had received placebo drinks. Alcohol also decreased the speed with which individuals were able to generate analytic responses in the classification task and decreased analytic performance on the embedded figures test. Alcohol slowed the rate of learning in the concept-learning task but did not lead to less analytic responding in that task. The results are consistent with the idea that alcohol slows the rate of information processing, particularly in tasks requiring visual analysis of stimuli. 相似文献

The purpose of this study is to examine the interrelationships among coping statements, a self-report measure of anxiety and maladaptive overt behavior in a real-life stressful situation. Measures of these variables (interviews using TAT-like cards, State-Trait Anxiety Inventory for Children, Behavior Profile Rating Scale) were taken from 23 adolescents prior to and during their dental visit. Results indicated that as disruptive "in-chair" overt behavior increased, so did the percentage of coping statements. In addition, as self-report levels of anxiety increased, the percentage of coping statements significantly decreased. Interestingly, there was no significant relationship between self-report levels of anxiety and disruptive in-chair behavior. It was also noted that the subjects' self-report levels of anxiety significantly decreased following their opportunity to verbalize their coping/noncoping statements via the TAT-like procedure. The implications of these interrelationships to cognitive-behavioral theory are discussed. 相似文献

This study measured students' attitudes toward a university's student health services (SHS) and identified factors that were related to their attitudes. A questionnaire surveying students' attitudes was administered to a sample of 150 students at the Oxford Campus of the University of Mississippi. Analysis of the data revealed that students' attitudes had a statistically significant correlation with the following variables: perceived medical care cost, amount of health information/education received during medical encounters, time spent in the waiting room of the SHS, sex of the student, and income of the student. There was no significant relationship between attitude and age. 相似文献

The relationship between basic research, theory, and clinical work with families is conceptualized during a discussion of Jamaican family structure and the application of change theory to a clinical case of depression in a Jamaican woman. It was found that three types of family structure are prevalent in Jamaica. The European ideal of a patriarchal-patrifocal structure creates problems for working-class Jamaicans. General system theory provides support for a different model. Change theory is applied to resolve the paradox created by the European model. 相似文献

In response to the article by Lamiell and Trierweiler (this issue), we examine the stated epistemological origins of idiothetic proposals for theory and research in personality We argue that the justification for those proposals as advanced by Lamiell and his colleagues is wholely insufficient in view of prior research on the consistency of behavior This assertion together with our identification of problems in scaling personality and personality consistencies lead us to conclude that the pursuit of the idiothetic method is both unwarranted and ineffectual 相似文献

Recent studies have provided strong support for the convergent validity of the General Behavior Inventory (GBI), a case identification inventory for chronic subsyndromal affective disorders (cyclothymia and dysthymia). Fewer data are available, however, on the ability of the GBI to distinguish chronic subsyndromal affective disorders from other forms of psychopathology. In order to address this issue, outpatients with cyclothymia (n = 9), dysthymia (n = 26), nonchronic major depression (n = 16), and nonaffective psychiatric disorders (n = 30) were compared on the GBI. Diagnoses were derived blind to GBI scores using structured diagnostic interviews and DSM-III criteria. The inventory significantly discriminated cyclothymes and dysthymes from patients with nonchronic major depressions and nonaffective disorders. Using the cutoff score that maximized GBI-diagnosis concordance, the inventory correctly classified 88% of the sample. All of the cyclothymes, 92% of the dysthymes, 87% of the patients with nonaffective psychiatric disorders, and 75% of the nonchronic major depressives were correctly classified by the inventory. These data provide strong support for the discriminant validity of the GBI. 相似文献
