This study tested whether sensitivity to aversive events is a concomitant versus antecedent/consequent of depression. Twenty currently depressed subjects, twenty subjects with remitted depression, and twenty control subjects completed psychophysiological and learning tasks involving aversive components. Both currently depressed and remitted subjects, when compared to control subjects, exhibited greater decreases in skin resistance response reactions to negative social scenes and a greater sensitivity to extinction in the learning condition involving an aversive component. The fact that the responses of remitted subjects were very similar to those of currently depressed subjects on both tasks is consistent with the view that sensitivity to aversive events is an antecedent or consequent of depression, as opposed to being only a concomitant. The results also provide some support for the passive avoidance model of depression.This study was based on portions of a doctoral dissertation by the first author, with the second author as chairperson, at the University of North Carolina at Greensboro.This research was aided by a Grant-in-Aid of Research to the first author from Sigma Xi, The Scientific Research Society, an award from the Jill Shelby Memorial Fund to the first author, and support from National Institute of Mental Health Grant MH17071, awarded to C. R. Snyder.Portions of this paper were presented at the meeting of the American Psychological Association, New Orleans, August 1989, and at the meeting of the Association for the Advancement of Behavior Therapy, Washington, DC, November, 1989. 相似文献

This study addressed the question: Do special education labels bias teachers' evaluations of children? Thirty primary level teachers were given different labels for the same child: learning disabled, educable mentally retarded, emotionally disturbed, normal, or no label. Teachers made behavioral observations from the same video-tape, completed a checklist, and graded the same academic work purportedly completed by the target child. Teachers' behavioral observations and grading of the academic work were not influenced by the special education labels, but the checklist scores were. Implications for the philosophical debate about the effects of labeling and for methods of classroom data collection by teachers are discussed. 相似文献

Behavior modification in the school setting has consisted primarily of the manipulation of consequent conditions to vary children's social and academic behaviors within classrooms. The scope of behavior modification within school settings may fruitfully be expanded by furthering the investigation and application of these additional areas: the interaction between the modification of social and academic behaviors, the manipulation of antecedent conditions in order to evoke reinforceable responses, the use of controlling variables on a school-system-wide basis, and the use of standardized tests as an additional dependent measure. 相似文献

This commentary addresses the use of psychometric theory and methodology in the development of the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Reliability issues include interdiagnostician reliability, temporally consistent diagnoses, and the relations of diagnostic criteria within categories. Validity issues include content validity of the diagnostic criteria, criterion-related validity (the relation between different criterion sets or their algorithms and alternative diagnostic criteria), and construct validity (the relation between diagnostic categories and external validators). Specific questions and methodology to investigate its utility vary with the different uses proposed for the diagnostic system. Specific psychometric methodologies that may be useful in developing the DSM-IV are noted, as are the limitations of psychometrics and their applicability to DSM-IV. 相似文献

Poor outcomes in ADHD may be related to problematic social functioning and consequences of social rejection. This study examines how ADHD symptom expression affects mood and social rejection. Working from findings in depression that describe maintenance through negative interpersonal interactions, the authors seek to examine this theory's applicability to poor outcomes in ADHD. In a completely randomized design, 130 participants are exposed to one of several videotape segments that include displays of ADHD, depression, and social anxiety. A normal control is also used. All abnormal videotapes are met with greater rejection than the control. Displays of ADHD elicit similar levels of rejection to those elicited by displays of depression. Additionally, ADHD elicits greater levels of hostile mood, whereas depression elicits high levels of depression and fatigue. Implications for an interpersonal theory of vulnerability in ADHD are discussed along with implications for future research, prevention, and intervention. 相似文献
