The paper reviews Wechsler Intelligence Scale for Children-Revised research that has particular pertinence for the assessment of learning disabilities (LD). Three topics are treated in-depth: factor analysis investigations, recategorization of subtests into Bannatyne's four groupings, and interscale/intrascale scatter. (Author)

Guttman's assumption underlying his definition of "total images" is rejected. Partial images are not generally convergent everywhere. Even divergence everywhere is shown to be possible. The convergence type always found on partial images is convergence in quadratic mean; hence, total images are redefined as quadratic mean-limits.…

As psychologists increasingly employ more elaborate and comprehensive data collection schemes, sophisticated analytic techniques will play an ever more important role in understanding behavioral data. This paper outlines one such promising technique, Tucker's three-mode factor analysis, which enables the researcher to explore new taxonomic…

A maximum likelihood method of estimating the parameters of the multiple factor model when data are missing from the sample is presented. A Monte Carlo study compares the method with five heuristic methods of dealing with the problem. The present method shows some advantage in accuracy of estimation. (Author/CTM)

Confirmatory factor analysis is considered from a Bayesian viewpoint, in which prior information concerning parameters is incorporated in the analysis. An interactive algorithm is developed to obtain the Bayesian estimates. A numerical example is presented. (Author/JKS)

Kaiser and Michael reported a formula for factor scores giving an internal consistency reliability and its square root, the domain validity. Using this formula is inappropriate if variables are included which have trival weights rather than salient weights for the factor for which the score is being computed. (Author/RL)

Investigates the capacity of the Zung Self-Rating Depression Scale for providing specific multidimensional descriptors of depressive behavior. Ideational, physiological and behavioral depression factors were evident in data from 96 normal, white university student volunteers. (Author/RH)

Results of this study imply substantial instrument bias in the learning styles inventory (LSI) and a modified Likert-scale version of the LSI. (RAO)

The latest revision of the Stanford Achievement Test (SAT), Primary Battery I, consists of seven subtests combined to yield three subtotal scores and one Total Battery score. A factor analysis was performed on the SAT-I scores of 927 beginning second-grade pupils. The analysis showed two correlated factors. (Author/CTM)

The squared multiple correlation of a variable with the remaining variables in a variable set is shown to be a function of the communalities and the squared canonical correlations between the observed variables and common factors. (Author/JKS)

Schaeffer's revised version of the Children's Reports of Parental Behavior Inventory was administered to 90 male delinquents. Factor analyses of their reports on both fathers and mothers yielded three factors: Rejection v Acceptance, Psychological Control, and Lax Control. The factor structures were similar in both analyses. (Author)

A simplified procedure for obtaining a weighted procrustes factor analysis rotation is presented in this brief note. Implications are discussed. (See also EJ 180 443). (JKS)

The distributional characteristics of Kaiser's Measure of Sampling Adequacy (MSA) were investigated in sample matrices generated from multivariate normal populations of specified correlation levels. Systematic variation of sample size and number of variables revealed the overall MSA to be most influenced by the number of variables. (Author/JKS)

The stability of factor structure of an instrument measuring managerial attitudes toward blacks in the working environment was investigated. Results indicated that the factor structure did not remain invariant over administrations to three different samples of managers. The implications for the psychological measurement of attitudes are discussed.…

One group of subjects responded to an anxiety battery according to their general feelings and then according to their feeling under anxiety-related simulations. A control group received no special instructions. Analysis of variance of factor scores indicated that simulations altered level of state anxiety but not trait anxiety. (Author/JKS)
