Subjects were intructed to select one rod to lie halfway in length between two given rods. These bisection instructions imply an additive model in the subjective metric. However, the data were inherently nonadditive; the length of the bisector could be an increasing or a decreasing function of the length of one given rod, depending on the length of the other given rod. A convexity analysis and a nonmetric analysis both showed that no monotone transformation could make the data additive. The bisection problem is used to contrast the axiomatic and functional approaches to measurement theory. 相似文献

The occupational values of a sample of 1958 ninth grade students were compared with those of a sample of ninth grade students in 1970. The overall order of rankings was similar, but some shifts did occur. These shifts suggest that 1958 ninth graders sought a stable enjoyable job, while the 1970 ninth graders hope for enjoyable work at high pay. 相似文献

This paper describes our experience during the past 2 years in establishing a computer-based laboratory for introductory psychology. Discussion includes selection of hardware; physical design of the laboratory; locating, reviewing, and selecting courseware; development of supplementary materials; operation and management of the laboratory; and integration of the laboratory into the curriculum. These factors are examined from the point of view of the decisions made, the difficulties encountered, and the lessons learned. 相似文献

This paper describes the development of COMPsych, a computerized system to disseminate information about software dealing with ail aspects of psychology. The need for such a service, the various components, and the general operation of the system are described. The system will contain a catalog of commercial and public domain software, a library of freeware, a directory of computer users, and a bulletin board. 相似文献

Some understanding of dynamical systems is essential to achieving competency in connectionist models. This mathematical background can be acquired either through a rigorous set of upper undergraduate and/or graduate formal courses or via disciplined self-teaching. As part of developing a course in connectionism, we feel that although certain very basic mathematical tools are most appropriately learned in their “pure” form (i.e., from mathematics textbooks and courses), more advanced exposure to dynamical systems theory can be given in the context of an introduction to connectionism. Students thus learn to write connectionist simulations by first writing programs for simulating arbitrary dynamical systems, then using them to learn some aspects of dynamical systems in general by simulating some special cases, and finally applying this technique to connectionist models of increasing complexity. 相似文献

Conflict is not an aberration but rather part of the structure of human relationships. It is defined in this paper as consisting of four stages. Once the first stage (the dispute) is triggered, there is a high likelihood that the second (blaming) will occur, and the third (shame, guilt, or denial), and then the fourth (reparation, reconciliation, or retaliation). Three case presentations illustrate the conflict cycle in various clinical and nonclinical situations. The family therapist should be readily able to identify the cycle in clinical situations, and knowledge of it should prove fruitful in identifying pathogenic relating and in planning interventions and their timing. 相似文献

Many recent reviews of the literature concerning behavioral treatments of obesity have concluded that behavioral methods have not been as successful in treating this problem as might have been predicted in the early years of behavior modification. Among the many potential reasons for this lack of success is the growing trend to utilize group statistical designs rather than single subject designs to examine the problem of obesity, in spite of the fact that single case methodology has provided the foundation for applied behavior analysis and behavior therapy. Several behavioral journals were surveyed to determine more precisely the trends in types of research strategies utilized in obesity studies. The potential relationship between research methodology and the development of effective treatments is discussed. 相似文献

To assess the factor structure of Calhoun's Youth Suicide Scale (YSS), 191 consenting undergraduates in one sample and 240 consenting undergraduates in a second sample wee given the YSS during class. From the second sample, 152 subjects also took the YSS a second time about 1 month later. In the first sample, three factors, which accounted for 50.0% of the variance, emerged. They were: How the Parents were Viewed (in terms of psychological disturbance, likability, and blame); Expected Responses to the Bereaved Family (terms of tension and sympathy); and Empathy with Parents (whether the newspaper was viewed as correct in reporting the cause of death, how long parents were expected to grieve, and whether parents were expected to be liked). In the second sample, the same three factors emerged (accounting for 55.5% of the variance), with the exception of one item on Factor 3: expecting to like the parents. Congruence coefficients between the three factors in the two samples were .98, .94, and .78, respectively. Reliability correlations on individual items ranged from a low of .30 to a high of .61. These results indicate that the YSS is valid, stable, and moderately reliable for assessing reactions to youth suicide; thus, it would be a viable instrument for use in future research on reactions to suicide. 相似文献
