The gains of scores on standardized intelligence tests (i.e., Flynn effect) have been the subject of extensive debate concerning their nature, causes, and implications. The aim of the present study is to investigate whether five intelligence tests are measurement invariant with respect to cohort. Measurement invariance implies that gains over the…

The experience of developing a set of comprehensive aptitude batteries for computer administration for the Air Force Human Resources Laboratory's Learning Abilities Measurement Program resulted in the formulation of nine principles for creation of a computerized test battery. These principles are discussed in the context of research on…

The differentiation hypothesis suggests that the degree to which general intelligence ("g") pervades performance on mental tests is greater at lower ability levels. Analysis of data from Differential Aptitude Test results for over 10,500 Irish school children ages 14 to 17 years supports the differentiation hypothesis. (SLD)

Navy recruits (n=243) participated in an examination of the relationship between strategy use and intelligence through paper-and-pencil and computer-administered tests that considered reaction time. Overall, results weaken arguments that strategy use is related to general intelligence and that strategy use is a robust, traitlike construct. (SLD)

The hierarchical and radex models of ability organization are shown to be parallel. Both suggest a complexity continuum for cognitive performance tasks which, in the radex model, corresponds to the general-to-specific dimension in factor analyses. The bases for this continuum indicate its importance for theories of intelligence. (Author/RD)

Fourteen estimates were made of "g" (general cognitive ability) from the normative sample of a multiple-aptitude test battery with a weighted sample representing 25,409,193 men and women. The methods, which included principal components, unrotated principal factors, and hierarchical factor analysis, are equivalent for this test. (SLD)

Individual differences in digit span, susceptibility to proactive interference, and various aptitude/achievement test scores were investigated in two experiments with college students. Results indicated that digit span was strongly correlated with aptitude/achievement scores, but did not indicate that susceptibility to proactive interference…

This article examines the potential contribution of latent trait models to the study of intelligence. Nontechnical introductions to both unidimensional and multidimensional latent trait models are given. Multidimensional latent trait models can be used to test alternative multiple component theories of test item processing. (Author/CTM)

There are economic advantages in using microcomputers as automated testing stations for measuring aptitude and intelligence. Microcomputers also make it possible to expand and modify testing procedures for psychological functions included in conventional tests and to test psychological functions not generally assessed by conventional tests, such…

The general intelligence factor (g) was investigated using 170 university students across three batteries of ability measures: (1) a short-term memory battery; (2) the Multidimensional Aptitude Battery; and (3) a reaction time battery. Results support the notion of g and suggest short-term memory as an essential aspect of intelligence. (SLD)

The functions that IQ and aptitude tests now serve in schools and the trends that may modify the present pattern of test use are presented. Current research on intelligence and aptitude and the kind of intelligence tests that might prove more useful in instructional planning are also discussed. (Author/RD)

Current studies of cognition emphasize the contrast between two approaches to analysis of individual differences. It is concluded that the cognitive components approach incorporates the cognitive correlates approach, avoids the inadequacy of correlational methods, and models individual differences on various dimensions of cognitive functioning.…
