Punitiveness in male movie-goers in London, Philadelphia, Rome and Toronto was measured before or after they attended films varying in content (aggressive, sexual, neutral) and arousal potential (low, high). A second dependent variable, altruism, was also assessed for some Ss. Hypotheses stemming from social learning theory and arousal theory were tested by comparing changes in punitiveness at aggressive, nonaggressive arousing (sexual) and nonaggressive nonarousing (neutral) films. At aggressive films there was an increase in punitiveness whereas a reduction in punitiveness was found at neutral films. Sexual films led to a smaller (nonsignificant) increase in punitiveness than aggressive films. The findings implied that arousal was a necessary, but not sufficient, condition for increasing punitiveness. There were no significant cross-national differences in response to the films. Since the results did not generalize to other, nonaggressive responses, the film effects may be aggression-specific. Two additional findings in the U.S. sample were that urban Ss were more punitive than rural Ss and that the length of urban residency correlated negatively with altruism. 相似文献

The method of triads for psychophysical judgments was analyzed in terms of the unidimensional unfolding model of Coombs (1964). This model predicts laterality effects on the stochastic transitivity of triples for which existing models have been unable to account. An experiment was conducted in which triadic judgments were made on circles differing in area. The results confirmed the stochastic transitivity predictions, but a quantitative formulation of the model proved unsatisfactory. 相似文献

A central assumption in portfolio theory of risk preference is that for games with expected value constant the preference ordering of an individual should exhibit a single peaked preference function. This assumption was tested by determining the level of stochastic transitivity satisfied by triples of pairwise preference proportions among eight gambles. In only a small percentage of cases were the predicted levels of stochastic transitivity not satisfied. It was concluded that the results provided strong support for portfolio theory. 相似文献

This paper examines seven independence concepts based on a preference relation on the set of simple probability measures defined on a set of multiattribute consequences. Three of the independence relations involve gambles and the other four are based on riskless preferences over the n-tuples in the consequence set. The main theorems state conditions under which one or more of the risky independence relations can be derived from a riskless independence relation in conjunction with other conditions. The other conditions include a risky independence condition which differs from the one(s) to be derived, the assumption that the consequence set is a convex subset of a finite-dimensional Euclidean space, and the assumption that the individual's von Neumann-Morgenstern utility function on the consequence set is continuous. 相似文献

In a successive discrimination four groups of pigeons were trained to discriminate between red and green. The groups differed with respect to the procedure used to introduce S?: Early-Progressive, Early-Constant, Late-Progressive, and Late-Constant. The aversive properties of S? were measured by an escape response in which a single peck at a second key terminated S? for 10 sec and darkened the chamber. The correlation between the aversive and error-producing properties of extinction was zero. More errors occurred when S? was introduced abruptly at a constant intensity while more timeouts from S? occurred when S? was introduced late. The procedure for introducing S? rather than the number of responses to S? appears crucial in determining how aversive S? becomes. 相似文献

A k-sample significance test for independent alpha coefficients 总被引:1,自引:0,他引:1
The earlier two-sample procedure of Feldt [1969] for comparing independent alpha reliability coefficients is extended to the case ofK 2 independent samples. Details of a normalization of the statistic under consideration are presented, leading to computational procedures for the overallK-group significance test and accompanying multiple comparisons. Results based on computer simulation methods are presented, demonstrating that the procedures control Type I error adequately. The results of a power comparison of the case ofK=2 with Feldt's [1969]F test are also presented. The differences in power were negligible. Some final observations, along with suggestions for further research, are noted.The authors gratefully acknowledge the assistance of Michael E. Masson, in the computations performed, and of Leonard S. Feldt, in suggesting the data generation procedures used in the study. In addition, the authors thank James Zidek and the Institute of Applied Mathematics and Statistics, University of British Columbia, for advice concerning some of the theoretical development. 相似文献

A classification system for visual-geometric illusions, based upon the interrelationships between behavioral responses to various distortions was created. Forty-five illusion configurations were presented to 221 observers. Factor analysis revealed that there are five classes of illusions. A secondorder analysis revealed that visual distortions are ultimately reducible to two global types of distortions: illlusions of extent and illusions of shape or direction. 相似文献

A technique is described that permits precise synchronization of video recorded behavior with discrete stimuli and responses. These discrete events are recorded as digital data on the video channel of a video recorder on a horizontal line that lies above the visible video information. These data may be observed in single-frame playback mode by underscanning the playback monitor. A circuit is described for computerized decoding of the digital data. Because each video field is uniquely coded, an updating of the data is possible 60 times each second. The described technique has several advantages over current approaches for synchronizing discrete stimulus and response events with video recorded behavior. 相似文献
