This report is of two studies. One is on developing a refined combination of predictors including ability, likability," and motivation"; the other is aimed at validating this multiple regression equation against actual school achievement. (Author)

This research was designed to investigate the relationship between a verbal measure of predictive ability and performance on selected science process tasks by prospective elementary school teachers. The vehicle utilized for assessing the comprehension ability was the cloze procedure, with the cloze score being considered as verbal predictive…

Describes the interest and concern of the membership of the Personnel Testing Council of Southern California in what may be the most critical issue in personnel testing today--the implications of using or not using g-loaded tests. Describes the events that led to the scheduling of a major conference on the g factor. Also describes audience…

Twenty-nine first grade monolingual English speaking children and 59 English second language children (given the Peabody Picture Vocabulary Test and the Raven Matrices in kindergarten) were tested via the Metropolitan Achievement Test to determine achievement levels of Italian children and the predictive relationship between measures of ability…

Analyzed several data sets to compare the prediction possible from a uniform general factor score with that produced by a separately tailored set of regression weights when those weights are applied to a new cross-validation sample. Found that with smaller samples, the uniform general factor score was clearly superior. (Author/ABB)

Study supported by National Science Foundation Grant No. GB-1742, "Ability Components of Skill Learning.

This study was designed to: (1) compare the contribution of various categories of biographical data (biodata) to the differentiation of college attenders and nonattenders, and (2) to assess the accuracy of biodata as a predictor of collete attendance. Subjects consisted of 20,367 high school senior males who participated in the 1960 data…

A battery of 11 nonverbal tests were administered to a sample of 2,362 non-prior service enlistees who had been selected to one of seven technical schools. The usefulness of additional aptitudinal and educational data was also investigated. The number of significant relationships between certain nonverbal tests and final technical school grade…

The asymptotic posterior normality of latent variable distributions is established under very general and appropriate hypotheses, providing a probabilistic basis for assessing ability estimation/prediction accuracy in the long test case, as well as a first step in making the Dutch Identity conjecture rigorous. (SLD)

This research explored the validation of a quantifiable, objective, and reliable method of measuring the amount of effort to be directly rewarded in incentive systems. A battery of relevant ability tests was given to a sample of Air Force trainees and to civilian subjects using a simulation of the course taught the Air Force trainees. Results…

Asserts that Spearman's g is a real phenomenon with great impact on economic and social life. Discusses key areas of personnel selection, vocational counseling, education, labor market functioning, and equal employment opportunity. (Author/ABB)

Reviews relationships of vocational interests with vocational-relevant variables (ability, success, and satisfaction). Results indicate no correlations between interests and actual relevant abilities and performance, but that a positive relationship exists with satisfaction. Suggests cognitive functions may mediate between actual abilities,…

This report describes new statistical procedures for item response analysis using estimation of item response curves used in mental testing with ability parameters treated as a random sample. Modern computer technology and the EM algorithm make this solution possible. The research focused on the theoretical formulation and solution of maximum…

Job analyses were compared with employees' self-ratings of abilities across 54 occupations. Participants totaled 2,272 workers (1,119 women and 1,153 men) who took the Career Decision-Making System as part of an effort to expand its concurrent validity evidence. The results supported the validity of self-assessment of aptitudes in career…
