Spontaneous analogical transfer is the use of information from one problem to solve another problem, without an explicit hint to use the previous information. The results of five experiments were that if subjects tried to solve a training problem before hearing its solution, or tried to explain a training story's solution before hearing the correct explanation, spontaneous transfer was more likely than it was if subjects had studied the same training passage for memory before hearing its solution or explanation. The advantage of problem-oriented processing over memory-oriented processing occurred even though solution attempts nearly always failed, and the advantage was not reduced if the target problem was tested 15 min later rather than immediately after training. We propose that problem-oriented processes performed at study are appropriate processes to use at test. Further support for the account comes from subjects' memory for the training passages; the advantage for problem-oriented processing on solution tasks was mirrored by an equally substantial advantage for the memory-oriented subjects on a recall task.  相似文献

Expands Barker's theory of behavior settings by proposing an additional method of classifying settings based on their functional/behavioral aspects--the setting phenotype. Although behavior setting theory has been widely hailed as a revolutionary contribution to behavioral science, it has had limited impact on general psychology. This may be due in part to a reliance on a purely structural method of classifying behavior settings--the setting genotype. Behavioral data were collected from 510 meetings of 13 self-help groups from a mutual help organization for persons with problems in living. A cluster analysis was performed to uncover meaningful behavioral patterns among the groups. Four phenotypes were identified: personal, impersonal, small talk, and advising. Mutual help group phenotype was found to be related to a set of setting characteristics as well as to overall rated change of group members. The results are discussed in light of the significance of the phenotype construct for making behavior setting theory more relevant for social scientists.  相似文献

A longitudinal organizational field study examined work satisfaction and employee growth coping as joint predictors of turnover. Three employee categories were examined: 1) No Turnover, 2) turnover within the same occupational field (Intraoccupational Turnover), and 3) turnover to a new occupational field (Interoccupational Turnover). Work satisfaction was moderate in the first two groups and low in the third group. As predicted, a specific strategy of employee coping, growth, was lowest in the first group, moderate in the second group, and highest in the third group. Through the use of linear discriminant analysis, 66.4% of the employees were correctly classified into No Turnover, Intraoccupational Turnover, and Interoccupational Turnover groups based only on information regarding work satisfaction and growth coping. The first squared canonical correlation was found to equal .30, far surpassing the modest work satisfaction/turnover correlations found in all previous studies.The authors wish to thank the two anonymous reviewers for their thoughtful comments.  相似文献

The crisis in mathematics education is likely to grow. One of the targets for reform is the math textbook, which largely defines the math curriculum. Several aspects of math textbooks that strongly influence student learning are explained: the organization of lessons, the use of time, the rate of introducing new concepts, the quality of instructional activities, the nature of the examples, and the provision of guided and independent practice. Excerpts from math texts illustrate these factors. Research findings on an alternative to basais, represented by the Direct Instruction math curriculum, illustrate how conceptual understanding and proficiency can be developed for a full spectrum of students.  相似文献

It has been suggested that deficits in selective attention play a functional role in the learning and behavior problems of children diagnosed as learning- disabled. In the present study, peripheral and central aspects of selective attention were distinguished and peripheral aspects were examined. The attending eye movements during reading of 12 fifth-grade learning-disabled children who read at the third-grade level were compared with 12 fifth-grade children who read at the fifth-grade level (grade placement controls) and 12 third-grade children who read at the third-grade level (reading level controls). The learning-disabled children did not differ from their reading level controls on any of W measures but showed a pattern of eye movements that was generally slower and less smooth than their grade placement controls. While these patterns might be considered to be immature relative to normal readers of the same age, they are not indicative of peripheral deficits in selective attention. Males, however, did exhibit more variability in duration of fixations and made more regressive eye movements than did females.  相似文献

This paper describes the development of the training programme offered at the Family Institute in Cardiff and presents the results of a retrospective survey reflecting the 'consumers' views of the programme. Questionnaires were sent to all students who had trained at the Institute between 1972 and 1977, to elicit information about their views of the placement, as well as their post-qualifying experience, activities and interest in family therapy. A briefer preliminary report has been published earlier (Dowling and Seligman, 1980).  相似文献

Two experiments are reported concerning the effects of the differential use of verbal approval by problematic adolescents serving as tutors in a remedial reading program for an inner-city school. The experiments, each with 3 tutors and 15 tutees, used a combined multiple baseline and ABCBC design. Data showed that tutors' approvals as well as tutors' and tutees' on-task and reading responses were low and stable during baseline. Tutors were trained to use verbal approval for tutees' on-task behavior. Tokens were presented and withdrawn to control the tutors' use of approval. During phases in which tutors' approvals were raised via token dispensation, tutor reading and on-task scores increased in a nonexperimental setting. Tutee reading scores also increased as a function of tutor approvals. The second experiment replicated these findings and, in addition, (a) tested the validity of changes in reading responses via standardized tests, (b) isolated and compared the covariance between variables in all phases, and (c) provided data on tutee attention to tutors as a possible natural reinforcer for the short-term maintenance found in both studies. Data are discussed as evidence that tutors had acquired the ability to recruit reinforcement from the classroom for appropriate behavior.  相似文献

The Tzeng and Tzeng (1982) criticisms of the assumptions underlying the Jackson, Chan, and Stricker (1979) study of Implicit Personality Theory fail to take account of the relevant empirical data. For example, the key contention of Tzeng and Tzeng–that the measures of judged and empirical trait-co-occurrence used by Jackson et al. were not comparable–is contradicted by replicated findings which establish that the two are substantially and consistently related, results for which Tzeng and Tzeng offer no alternative explanation. In short, Tzeng and Tzeng have not demonstrated that their criticisms have any real substance. Hence, none of the Jackson et al. results and conclusions, including those questioning the conditional probability index as a measure of empirical co-occurrence and those supporting the validity of Implicit Personality Theory, are affected or changed.  相似文献

A large battery of behavioral tests was administered to normal mice and to mice with varying degrees of otoconial agenesis due to genes affecting vestibular development. Many significant differences were found, but a factor analysis revealed that the variance on the 11 best tests could be accounted for in terms of two underlying variables. Factor I, the more important of the two, was associated with activity, habituation, and spontaneous alternation. Factor II appeared to represent a fear of new stimuli or situations. In both cases factor scores were highly related to the degree of otoconial deficiency. One subgroup of mice with severe otoconial agenesis displayed hyperactivity and a total absence of either habituation or spontaneous alternation. In these animals, brain and body development were stunted, and the reactions to amphetamine and physostigmine were opposite to those seen in normal mice. The results support the idea that the static organs contribute importantly to spatial orientation and suggest that early-onset vestibular defects can result in profound alterations of emotionality.  相似文献
