Zusammenfassung Nach der kognitiven Dissonanztheorie steigt die Attraktivität einer Aufgabe nach Mißerfolg, wenn die Vp die Aufgabe zuvor selbst gewählt und nicht zugewiesen bekommen hatte. Nach der Leistungsmotivationstheorie ist die Attraktivitätsänderung abhängig von einer durch den Mißerfolg verursachten Verringerung der erlebten Erfolgswahrscheinlichkeit in Wechselwirkung mit der Ausprägung des überdauernden Leistungsmotivs der Vp. Ändert sich die Erfolgswahrscheinlichkeit in Richtung auf eine Höhe von 30–40%, so steigt die Attraktivität der Aufgabe für erfolgszuversichtlich motivierte Vpn und fällt ab für mißerfolgsängstlich motivierte Vpn.In einem 2×2-Versuchsplan wurde Wahl oder Zuweisung der Aufgabe mit vorwiegendem Erfolgsmotiv der Vp kombiniert. Aus einer selbsthergestellten Attraktivitätsrangfolge von 9 verschiedenen Aufgaben wählt die Vp zwischen der 5. und 6. Aufgabe eine zur Bearbeitung aus oder erhält eine der beiden fest zugewiesen. Nach Mißerfolg stellt die Vp eine erneute Attraktivitätsrangfolge der Aufgaben her.Die innerhalb und zwischen den vier Bedingungskombinationen erhaltenen Ergebnisse entsprechen zu einem größeren Teil der Leistungsmotivationstheorie als der Dissonanztheorie. In der Bedingungskombination, für die beide Theorien gegensätzliche Voraussagen machen (Wahl-Mißerfolgsmotivierte), fallen die Befunde zugunsten der Leistungsmotivationstheorie aus. Diese Theorie zeigt jedoch Schwächen in der Voraussage von Attraktivitätsänderungen unter Zuweisungsbedingungen. Die Dissonanztheorie versagt bei den Mißerfolgsmotivierten. Verbesserungen der Theoriebildung und der experimentellen Prüfung werden erörtert.
Change in attractiveness of task after failure. Cognitive dissonance theory versus achievement motivation theory
Summary According to cognitive dissonance theory, the attractiveness of a task increases after failure only when the S has chosen the task but not when it is assigned to him. Achievement motivation theory, on the other hand, states that change in attractiveness depends on a reduction in perceived probability of success, caused by failure. In addition, probabilitiy of success also interacts with the dispositional characteristics of the S's achievement motive. If probability of success increases toward a value of 30–40 per cent, then the attractiveness of the task increases for hope of success Ss but decreases for fear of failure Ss.Choice or assignment of task was combined with predominantely hope of success or fear of failure Ss in a 2×2 experimental design. The S first ranked nine different tasks in their order of attractiveness. While some Ss could further choose to work on either the fifth or sixth ranking task, other Ss were assigned either one of these tasks. A second ranking of attractiveness was obtained after a failure experience.The results, both within and between the four experimental conditions, support mainly the predictions of achievement motivation theory rather than cognitive dissonance theory. In the condition in which opposing predictions can be derived from the two theories (i.e., when choice is offered to fear of failure Ss), the results clearly favor achievement motivation theory. However, this theory is less adequate in predicting changes in task attractiveness under task assignment conditions. Dissonance theory appears to be unable to predict the behavior of the fear of failure Ss. Implications for changes in the theories and further empirial tests are discussed.相似文献

Several lines of evidence indicate that a parent's depression may be a significant health and adaptational risk factor for his or her children. In a controlled comparison, children of 133 depressed parents had significantly more symptoms of emotional, somatic, and behavioral impairment than did children of 135 nondepressed parents. Additional results suggest that the more negative milieu found among families of depressed parents was a mediator of the effects of parental depression. A social-environmental perspective helped to identify aspects of parents' functioning, family stressors, and resources that were related to children's health. Variations in these stressors and resources were strongly related to the probability of disturbance among children of depressed parents.We gratefully acknowledge the assistance of Sarah Buxton, Marlene Koltin, Ruth Lederman, Roger Mitchell, and Deborah Shields in data collection and of Dani Lawler in data collection and analysis.

A scaling technique developed by Bandura for determining an individual's personal performance expectations (self efficacy) was applied to student clinicians working with stutterers. The self-efficacy scores of clinicians conducting treatment increased significantly while the scores of clinicians without treatment experience showed no significant change. As the student clinicians gained clinical experience there appeared to be a corresponding reduction in fear and avoidance of the treatment situation. Clinician fear concerning stuttering treatment appeared to have little relation to performance in treatment as rated by supervisors. The results indicate that self-efficacy scaling may be used to indicate clinician avoidance of working with stuttering clients. 相似文献

Investigating the effects of insulin on carbohydrate metabolism and on the central nervous system (C.N.S.) under conditions of rest and of stress in dogs and in rats, using the conditional reflex method and measuring the nitrogen and phosphate brain metabolites and the blood sugar differences, the author found that cerebral glucose metabolism is dependent upon insulin, and that if glucose supplies are adequate, insulin stimulates C.N.S. performance within 15–20 minutes. The C.N.S. and blood sugar reactivity depend upon the environmental situation: the conditional stimuli for stress increase glycemia. Animals under stress went into shock even though their glycemic levels were relatively high, whereas those at rest did not go into shock or sometimes reacted with slight symptoms of somnolence even at a lower glycemic level. In experimental hyperglycemia the level rises even more during stress, with ensuing coma, especially with larger doses of insulin. An increase of inhibition with reduced learning precedes the glycemic irregularities. Thus, insulin directly influences the central nervous system. 相似文献

Zusammenfassung In diesem Aufsatz wird ein neues Paradoxon vorgestellt, der Super-Lügner. Er ist stärker als alle bekannten Lügner-Sätze, nicht mehr eindeutig selbstreferentiell und läßt sich darüber hinaus nicht eindeutig in die Tarski-Hierarchie einordnen. Eine unendlich große Familie von Super-Lügnern auf Metaebenen ist konstruierbar. Schließlich widersetzt sich der Super-Lügner der Auflösung durch die neue vielversprechende Reflexionslogik LR von U. Blau. 相似文献

Reactions to self-discrepant feedback were theoretically and experimentally investigated. The conceptual frame was provided by the theory of symbolic self-completion. Starting from the assumption that attitudes can function as central aspects of self-definition, 81 female subjects were either presented with feedback that their attitudes were unfeminist (treatment, i.e. incompleteness condition) or they received no feedback (control condition) Then they were given the opportunity for self-symbolizing by subscribing to a feminist journal. Subjects with strongly pro-feminist attitudes who were made incomplete with respect to their feminist self-definition subscribed more often and more intensively to the feminist journal than others. The results illustrate that attitudes can take on the character of self-definitions. Furthermore, reactions to self-discrepant feedback concerning a central attitude were as predicted by the theory of symbolic self-completion. 相似文献
