A description of a Fortran program for linear and area transformations of test scores with optional generation of symmetric tables of areas under the standard normal curve is presented. Also included is a historic note on the origin of McCall's T Scale. (Author/JKS)

A computer program is described which provides point-biserial coefficients of correlation and comprehensive response analyses for tests, questionnaires, and rating scales. The program can be executed with as few as three control cards. Data with missing observations, and more than one data deck can be analyzed at one time. (Author/JKS)

A computer program providing comprehensive test and item analysis is presented. Completing its performance on one run, the program, written in Fortran and emphasizing ease of use, integrates various statistical techniques for analyzing individual items and the overall test, in addition to generating a variety of standard scores. (Author/JKS)

This program generates maximum likelihood estimates of the parameters of a mixture of two normal distributions and tests the significance of the mixture hypothesis against that of a single normal distribution. (Author)

Conventional paper-and-pencil testing was compared to computer-assisted testing on a pharmacy school pathology test. Individual items were speeded in the computer-assisted mode. In addition to responses, the number and pattern of changes in responses were analyzed. True-false, multiple-choice and matching items were used. (JKS)

Nomothetic and idiographic approaches to the study of individual differences and individuality are discussed. It is argued that traditional nomothetic and idiographic perspectives are limited and alternative perspectives are offered. Computer simulation is proposed as a methodology for examination of these alternative perspectives. (Author/JKS)

Using words of known selection values arranged in a counterbalanced order, it was shown that subjects' ratings of the "imagery value" of each word resulted in error which favored the first position in the series when stimuli were homogeneous. The error did not occur with words which were markedly heterogeneous. (Author)

Response processes of undergraduates describing familiar peers of the same sex were investigated. Subjects described persons by responding to items adapted from Jackson's Personality Research Form. Subjects also reported item ambiguity, inappropriateness, etc. Results suggest that similar processes are involved in describing self and others.…

Testing procedures which involve testees assigning probabilities of correctness to all multiple choice alternatives is examined. Two basic assumptions in these procedures are reviewed. Empirical examinee response data are examined and it is suggested that these assumptions should not be taken lightly in empirical studies of personal probability…

In at least two situations, use of the Spearman-Brown prophesy formula yields overestimates of the interobserver reliability of composite scores. The appropriate formulas for estimating the interobserver reliability of composite scores, as well as efficient means of estimating the elements in these formulas are presented. (Author)

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.…

A convenient, two-stage general linear regression approach to analysis of variance is described for use in univariate or multivariate designs involving one repeated measurement factor and one or more independent classification factors. A brief illustrative example is provided. (Author)

A review of the development of canonical correlation is presented and insufficiencies in applications from the literature are summarized. A list of analytical procedures for use in canonical correlation is detailed. The relationship between analysis and interpretation is emphasized. An example is presented. (JKS)

Studies concerning the relation of sample size to the number of variables in factor analysis are reviewed. It is noted that constraints imposed on the dimensionality of the variables by having fewer observations than variables are not mentioned in the literature. Suggestions for resolution of the problem are made. (Author/JKS)

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)
