We examined the use of self-monitoring to increase the productivity of five mentally retarded adults in a sheltered workshop. Data were collected daily during a 30-minute intervention and 30-minute generalization period. Following baseline, verbal praise, prompts, and physical encouragement were administered contingent on productive behavior on a specific task during the intervention period. In the next phase, self-monitoring was trained during the intervention period. During both phases, baseline conditions prevailed in the generalization periods. In the final phase, self-monitoring was extended across the intervention and generalization periods. Results showed that increased productivity levels, evident when praise and prompting were being administered, maintained with self-monitoring alone. Minimal generalization across time was observed until self-monitoring was begun in the generalization period. 相似文献

Results of 3 experiments examining the relationship between creativity and left-hemisphere and right-hemisphere EEG activity are reported. Creativity has been hypothesized to involve the use of primary-process cognition, and such cognition is hypothetically accompanied by activation of the right cerebral hemisphere. In light of these hypotheses, we predicted that highly-creative people should exhibit greater right-hemisphere than left-hemisphere EEG activity during creative performance and that this pattern would not be found in less-creative people. All 3 experiments supported this prediction. This difference in asymmetry was specific to creative performance. It was not present during basal recordings or during a non-creative task. 相似文献

A series of four experiments investigated college students’ judgments of interevent contingency. Subjects were asked to judge the effect of a discrete response Itapping a wire) on the occurrence of a brief outcome (a radio’s buzzing). Pairings of the possible event-state combinations (response-outcome, response-no outcome, no response-outcome, no response-no outcome) were presented in a summary-table (Experiments 2 and 4), in an unbroken-time-line (Experimente 1, 2, and 4), or in a broken-time-line format (Experiment 3). Subjects judged the extent to which the response caused the outcome or prevented it from occurring. Across all methods of information presentation, judgments were a positive function of response-outcome contingency and outcome probability. In the unbroken-time-line condition, judgments of negative response-outcome contingencies were less extreme than judgments of equivalent positive contingencies. This asymmetry was smaller in the broken-time-line condition and in those conditions in which subjects were encouraged to segment an unbroken time line into discrete response outcome units. Finally, judgments of positive and negative relationships were generally symmetrical in the summary-table condition. Relative to the two time-line portrayals, summary table judgments were also less influenced by the overall probability of outcome occurrence. These judgment differences among format conditions suggest that, depending on the method of information presentation, subjects differently partition event sequences into discrete event pairings. 相似文献

This study examined the relationship of preexisting efficacy for exercise with perceptions of effort expenditure and in-task affect during exercise testing. Subjects comprised sedentary, middle-aged adults participating in a submaxi-mal cycle ergometer-graded exercise test. Perceptions of efficacy were assessed prior to and following exercise testing while perceptions of effort expenditure and in-task affect were assessed at 70% of predicted maxim heart rate. Highly efficacious subjects had lower perceptions of effort expenditure and reported more positive affect during exercise than did their less efficacious counterparts. Affective responses during exercise were in turn significant predictors of posttest self-efficacy. These results are discussed in regard to the importance of examining the role of personal efficacy in the formation of exercise-related affect and affective responses as sources of efficacy or competence information in exercise. 相似文献

Researchers have typically portrayed intrinsic and extrinsic motivation as dichotomous. Although this dichotomy has explanatory utility, we present a differentiated view of extrinsic motivation, arguing that the relative autonomy of one's motivated actions is more useful for characterizing the motivational basis of learning than is the undifferentiated intrinsic-extrinsic dichotomy. Our concept of autonomous extrinsic motivation is based on a developmental analysis of the processes of internalization and integration. In this article we review extensive research indicating that intrinsic motivation and integrated internalization are facilitated by autonomy supportive social contexts, and that these autonomous forms of motivation, in turn, promote high-quality learning.Preparation of this article was facilitated in part by research grant HD-19914 from the National Institute of Child Health and Human Development to the Human Motivation Program in the Department of Psychology at the University of Rochester. 相似文献

The cult controversy has now spanned two decades. New religious movements clearly have engendered considerable opposition, but there is relatively little information concerning the impact of the cult controversy on public opinion. This article reports on the results of a national survey of both the general public and institutional elites. Support for four specific forms of social control was assessed. The results indicate considerable support for controls among the general population but lower levels of support among institutional elites. The least support is observed for blocking publication of the Unification Church sponsored Washington Times and the greatest support is registered for prohibiting proselytization of teenagers by all new religious groups. The findings are helpful in interpreting the outcome of the cult controversy to date and suggest that the potential for redrawing church-state boundaries remains. 相似文献

Three experiments examined the effect of context on the representativeness ordering of exemplars of a category. Experiments 1 and 2 employed an online reading time paradigm to examine the effect of context on the time it takes to establish an anaphoric reference between an exemplar and a category term. Experiment 1 demonstrated that context can change the relation between a category term and an exemplar at the time of comprehension. Experiment 2 showed that category terms presented in context generate graded goodness-of-example distributions of exemplars that are different from the distributions generated in the absence of explicit context. These distributions cannot be derived by assuming that the exemplar most strongly suggested by the context serves as the category representation. Experiment 3 employed a membership verification paradigm. Response time was found to be a function of degree of relatedness to the contextdependent category representation. Typicality, as determined in the absence of explicit context, had no effect on decision time. Several models, including some extensions of current semantic memory theories, are developed to account for the results of these experiments. 相似文献
