Two lines of psychometric interest are combined: a) multidimensional scaling and, b) factor analysis. This is achieved by employing three-mode factor analysis of scalar product matrices, one for each subject. Two of the modes are the group of objects scaled and the third is the sample of subjects. Resulting from this are, an object space, a person…

It is concluded that the techniques of automatic indexing and factor analysis are appropriate tools for curriculum analysis. However, the techniques need to be refined, and more care needs to be taken to insure that the criteria for the selection of data for the study are objective. In addition to predicting future developments, the data resulting…

The relationship between variations in an auditory signal identification task and consequent changes in the abilities related to identification performance was investigated. Characteristics of the signal identification task were manipulated by varying signal duration and signal-to-noise ratio. Subjects received a battery of reference ability tests…

In the last decade, curriculum specialists in the Language Arts have expanded the field to include listening. A compelling reason for increasing the listening training of first grade and preschool children lies in their "listening readiness." They are required to listen for information in order to learn, follow directions, participate in…

Presented at a symposium on "The Structure of Concept Attainment Abilities Project: Final Report and Critique," this paper provides the methodological aspects of the project. The discussion centers around a "Guide to the Multivariate Methods," which is provided in the paper. The basic guide-posts are the types of analysis and the types of content.…

Gradient methods are employed in orthogonal oblique analytic rotation. Constraints are imposed on the elements of the transformation matrix by means of reparameterisations. (Author)

Results of four studies in which the semantic differential was used to evaluate teaching effectiveness of professors at the university level are presented. Conclusions based on comparisons between factors isolated in the four studies, as well as between these four studies and other data, are as follows: (1) some factors such as teaching dynamism,…

This is a methodological study that suggests a taxometric technique for objective classification of yeasts. It makes use of the minres method of factor analysis and groups strains of yeast according to their factor profiles. The similarities are judged in the higher-dimensional space determined by the factor analysis, but otherwise rely on the…

The objectives of this study were (a) to examine the dimensionality of the Thorndike Dimensions of Temperament (TDOT) when administered in a single stimulus form; and (b) to test a set of hypotheses relative to the constructs measured in the TDOT. (Author/RK)

Q factor analysis is found appropriate for use in clinical or educational situations where available typologies or scales seem inadequate, where the psychological dynamics of learning or treatment are not well understood, or where it is desirable to avoid anticipating the precise direction and character of program impact. (Author/BJG)

The purpose of this study was to investigate the relationships among nine relatively independent factors of attitude toward quantitative concepts and measures of quantitative and verbal aptitudes. (Author)

Path analytic techniques for assessing the validity of indicators in multitrait-multimethod matrices represent improvements on Campbell and Fiske's early procedures for testing for validity. The diagnosis of indicator ills by means of confirmatory factor analysis is especially useful. An empirical example of these techniques is presented.…

Two proposed methods of factor analyzing a correlation matrix using only the off-diagonal elements are compared. The purpose of these methods is to avoid using the diagonal communality elements which are generally unknown and must be estimated. (Author/JKS)

A group of 31 clients completed the Human Service Scale and were evaluated by their counselors, who used the Client Outcome Measure at the time of the clients' acceptance for rehabilitation services and again at closure. Results were generally consistent with those of previous investigations. (Author)

Several nonmetric multidimensional scaling random ranking studies are discussed in response to the preceding article (TM 503 490). The choice of a starting configuration is discussed and the use of principal component analysis in obtaining such a configuration is recommended over a randomly chosen one. (JKS)
