An individual differences model for multidimensional scaling 总被引:3,自引:0,他引:3
A quantitative system is presented to permit the determination of separate multidimensional perceptual spaces for individuals having different viewpoints about stimulus interrelationships. The structure of individual differences in the perception of stimulus relationships is also determined to provide a framework for ascertaining the varieties of consistent individual viewpoints and their relationships with other variables.This research was supported in part by the National Institute of Mental Health, United States Public Health Service, under Research Grants M-2878 and M-4186 to Educational Testing Service, in part by Educational Testing Service, and in part by the Office of Naval Research under Contract Nonr-1834(39) and the University of Illinois. The authors wish to thank Drs. Harold Gulliksen and Douglas N. Jackson for their helpful comments and Miss Henrietta Gallagher for supervising the computations. Portions of this paper were presented at the American Psychological Association meetings in Chicago, September 1960.This paper was written while Dr. Messick was a Fellow at the Center for Advanced Study in the Behavioral Sciences. 相似文献

A sample of entering college freshmen was divided into 2 groups on the basis of the consistency or inconsistency of their first and second career preferences. The two groups were compared on several family and personal factors in order to identify variables that are related to inconsistencies in career preferences. The groups were observed to be somewhat different in the general level of their academic ability and the degree to which their interests were supported by SVIB results. No significant family differences between the two groups were observed. These findings were tentatively interpreted as implying that the inconsistency of career preference was more likely to be the result of the student's recognition of his limited abilities than the other variables examined in this study. 相似文献

Case IV of the Kuder-Richardson series, their formula (21), is derived as a generalized split-half Spearman-Brown coefficient. The basic assumption employed is shown to be sufficient to justify the various assumptions used in derivations by other authors. Some of the implications of this assumption are discussed. 相似文献

On methods in the analysis of profile data 总被引:39,自引:0,他引:39
This paper is concerned with methods for analyzing quantitative, non-categorical profile data, e.g., a battery of tests given to individuals in one or more groups. It is assumed that the variables have a multinormal distribution with an arbitrary variance-covariance matrix. Approximate procedures based on classical analysis of variance are presented, including an adjustment to the degrees of freedom resulting in conservativeF tests. These can be applied to the case where the variance-covariance matrices differ from group to group. In addition, exact generalized multivariate analysis methods are discussed. Examples are given illustrating both techniques.We are indebted to Mrs. Norma French for performing all the calculations appearing in this paper. 相似文献

Twenty couples living together, 10 married and 10 unmarried, were given the Bem Sex-Role Inventory and a questionnaire on the performance of household responsibilities. Findings provided partial support for hypotheses relating more traditional sex roles, living arrangements, and division of household responsibilities. Results also indicated a greater variability in household responsibilities for unmarried males and for males and females who were not traditionally sex typed. The latter results support a model which was formulated relating changes in sex-role attitudes with changes in sex-related behavior. In this model, a period of uncertainty intervenes between the change in attitude and the change in related behavior. 相似文献
