Two experiments examined whether individuals who ascribe the disparity in the performances of two actors to situational constraints adequately adjust their dispositional inferences to reflect their own perceptions of causality. Using the quiz-game format of L. D. Ross, T. M. Amabile, and J. L. Steinmetz (1977, Journal of Personality and Social Psychology, 35, 485–494), the effects of the subjects' awareness of the role-determined, self-presentation advantage of the questioner on their dispositional inferences concerning the quiz-game participants are noted. It is hypothesized that subjects who indicated full awareness of the determining force of the situation would nevertheless draw more favorable dispositional inferences about the questioner than about the contestant. The prediction is confirmed. Although the situationally aware subjects rate the questioner and contestant more similarly than do the other subjects, they still rate the questioner higher in knowledge, memory, and education. The results of Experiment 2 indicate that increasing the salience of the subjects' assessment of the situational advantage of the questioner does not eliminate the disparity. It is proposed that the fudamental attribution error represents more a failure to adjust trait inferences for causal attributions than a misperception of causality. Implications concerning the relationship between knowledge of causality and social judgment and the utility of the distinction between “perceived causality” and “higher order causal inferences” are discussed. 相似文献

The five stages of family development and their phase-specific tasks as delineated by Michael A. Solomon in an article that appeared in this journal (1973) are given dramatic representation by Virginia Woolf in her novel To the Lighthouse (1927). The novel begins with the Ramsay family system arrested at the third stage of development; and it is only after the death of Mrs. Ramsay that the remaining family members begin to attend to the phase-specific tasks of stages four and five, and family development commences. 相似文献

We begin our discussion by outlining the usefulness of "resource theory" as a theoretical framework for the study of family power. This framework is then used to analyze changes in the balance of power between elderly parents and their middle-age children. With respect to intergenerational power relationships, we argue that the autonomy of elderly parents has increased, but their power and influence over adult children has decreased. This trend is likely to continue in coming decades. Resource theory is then utilized to analyze changes in marital power relationships as couples age. Most studies of power relationships between elderly spouses have an important limitation--they tend to reflect yesterday's definitions of male and female roles. Recent changes in these roles may significantly alter the social meanings of aging for both men and women in coming years. 相似文献

We investigated the programming of generalization and maintenance of correspondence between verbal and nonverbal behavior in a preschool setting. Four children participated in a series of multiple-baseline designs. In Experiment 1, delayed reinforcement of verbal behavior effectively controlled maintenance of correspondence with previously trained responses and also resulted in generalization of correspondence to one untrained response. As the latter effect was limited, Experiment 2 was a further assessment of the effects of delayed reinforcement of generalization of correspondence to untrained responses, and consistent generalization was shown. Experiment 2 also showed that generalization, if lost, could be recovered through use of "booster training," in which the original contingencies were reinstated for a brief period. Experiment 3 provided replications, with two additional children, of the effects of delayed reinforcement on maintenance of correspondence. Results are discussed in terms of using delayed reinforcement as an indiscriminable contingency. 相似文献
