In two separate experiments, 80 introductory psychology students completed a two-cue probability learning task in which cue intercorrelation was positive or negative and cue validities were positive or negative. Results indicated that Ss did not learn the negative validity tasks. In addition, there were no significant differences between groups in achievement due to cue intercorrelation within any one experiment. However, the positive redundancy groups were significantly more consistent in the employment of their decision strategy than the negative redundancy groups when cue validities were positive. The negative redundancy groups were superior to positive redundancy groups in matching; again, when cue validities were positive. 相似文献

A system is described which permits the average instructor, without programming knowledge, to prepare a simulation model that can be called up by students as a simulated experiment. 相似文献

Drawing upon his work in medical centers, Caplan explores the question of how well ethicists function in hospitals. He asks if their use of the "engineering model" of applied ethics, which emphasizes conceptual clarification, mastery of ethical theory, and impartiality, has made any difference in the way medicine is practiced. Noting that ethicists have been more effective in influencing heatlh policy at the national than at the institutional level, Caplan concludes that they have been less successful in teaching medical ethics, working with health personnel, and helping to formulate hospital policies. He attributes their difficulties primarily to the inadequacies of the engineering model of applied ethics for solving problems in a clinical setting. Caplan cautions ethicists to be aware both of the limitations of the engineering model and of the motives of health personnel in asking for help which may have little to do with resolving moral dilemmas. 相似文献

The differential effects of inbreeding on 11 subtests of the WISC, in a Japanese (Hiroshima) population, are related to the factor structure of the tests. The degree of inbreeding depression on mental abilities is most strongly correlated with the subtests' loadings on the General factor, g, which is common to all of the subtests. Loadings on the Verbal factor are also positively correlated with inbreeding depression. The (non-verbal) Performance factor, however, is slightly enhanced by inbreeding. One possible inference from these findings is that at least the General factor shows genetic dominance, which is theoretically consistent with natural selection for g in the course of human evolution. It is also noted that the factor structure of the WISC in the Japanese population is highly similar to that of the U.S. standardization sample. 相似文献

The illusion of knowing is the belief that comprehension has been attained when, in fact, comprehension has failed. In the present experiment, the illusion was defined operationally as having occurred when readers who failed to find a contradiction in a text rated their comprehension of the text as high. Texts containing contradictions between adjacent sentences were presented, and readers were explicitly asked to search for contradictions. The frequency of illusions was greater when the contradictory sentences came at the end of three-paragraph texts rather than at the end of one-paragraph texts and when the contradictory information was syntactically marked as new. These results are interpreted within a framework that emphasizes that the goal of reading expository text is to establish coherence within and among sentences. In addition, the results are apparently incompatible with the notion that readers engage in active and accurate on-line monitoring of the degree to which this goal is met. 相似文献

A course of psychological education is described in which disruptive children were taught social and communication skills over two terms. The course was designed for 26 eight-year-olds in an EPA junior school. Ten of the children were from broken homes, six were itinerants, most had displayed undesirable behaviour, and their level of achievement had been below average. Tested at the end of the second term, they showed dramatic improvements in self-concept and reading ability. 相似文献
