Holland's (1973) theory of vocational choice proposes a typology of, and a match between, people and occupations. The Self Directed Search (SDS) can be used to assess people's occupational orientation types. To assess the construct validity of Holland's theory of occupational preferences, 171 female industrial workers participated in a study,…

The perceived similarity of Holland's vocational personality stereotypes was examined using the techniques of nonmetric multidimensional scaling. Three job titles (JTs) were selected for each of Holland's stereotypes. These 18 JTs were then randomly paired. The resulting 153 pairs comprised an inventory which was administered to all students in a…

A maximum likelihood estimation procedure is developed for the simple and the weighted additive models. The data are assumed to be taken by either one of the following methods: (1) categorical ratings--the subject is asked to rate a set of stimuli with respect to an attribute of the stimuli on rating scales with a relatively few observation…

An hypothesis concerning a definition of the concepts assimilation and accommodation was tested. Both assimilation and accommodation were hypothesized to be processes that produce changes in cognitive structures--internal representations used to organize behavior. The hypothesis is that, in contrast to assimilation, the changes in structure caused…

This report describes a test of the robustness of factor-analytic methods in the face of various types of scale transformations on the data. Because of the complexities that would be involved in an exact analytical investigation, the tests were done with simulated sets of data having different factor structures. After factor analyzing the original…

The Cartesian theory of dimensionality (defined in terms of geometric distances between points in the test space) and Leibnitzian theory (defined in terms of order-generative connected, transitive, and asymmetric relations) are contrasted in terms of the difference between a factor analysis and an order analysis of the same data.

Two sets of five items each from the Law School Admission Test were analyzed by two methods of factor analysis, and by the Krus-Bart ordering theoretic method of multidimensional scaling. The results indicated a conceptual gap between latent trait theoretic procedures and order theoretic procedures. (Author/CTM)

Describes the loglinear model, and applies it to categorical data cross-tabulated on four dimensions. Defines contrasts similar to those of the analysis of variance and describes post hoc and planned comparison strategies. Illustrates hypothesis testing and model building for categorical data, providing guidelines for performing an analysis on…

Young, middle-age, and old adults ranked similarities of word pairs in a conditional rank-ordering task. Analyses of variance revealed an age-related decline in semantic processing but no such decline for elaboration. Older adults' retrieval was less compatible with initial processing than was the case for younger adults. (Author/ABB)

INDSCAL analysis, based on bipolar ratings of physically agressive incidents by 217 subjects, yielded a solution in three dimensions: Provocation by Target, Intimates vs. Strangers and Harmful Outcome. One bipolar scale, the Right-Wrong Scale, was used as a direct measure of subjects' moral evaluation of each incident. (Author/LMO)

Demonstrated a set of research techniques that combine multidimensional scaling, a quantitative cognitive procedure, and a cost-outcome analysis to study subgroup behavior of obsessive-compulsives (N=12). Results indicated that obsessive-compulsives are underinclusive in their evaluation of stimuli during judgment task. (LLL)

This study was designed to explain how Profile Analysis via Multidimensional Scaling (PAMS) could be viewed as a structural equations model (SEM). The study replicated the major profiles extracted from PAMS in the context of the latent variables in SEM. Data involved the Basic Theme Scales of the Strong Campbell Interest Inventory (Campbell and…

This paper confronts two interrelated problems, that problem dealing with the psychological concept of attitudes and the problem of attitude measurement. (Author)

Paper reports on the use of a technique of item writing and item keying in personality scale construction which overcomes the drawbacks, while maximizing the advantages of unit response weighting. (Author)
