The current study examines the views of experts in the science of mental abilities about the primacy and uniqueness of "g" and the social implications of ability testing, and compares their responses to the views of a group of non-expert psychologists. Results indicate expert consensus that "g" is an important, non-trivial determinant (or at least…

The general ability factor (G), as enunciated by Charles Spearman in the model of cognitive functioning, has been the foundation of psychometric theory and test making practices for 80 years. Through these decades, some psychologists disagreed with this theory, especially Godfrey Thompson and E. L. Thorndike. Nevertheless, various aptitude tests…

Raven's Progressive Matrices test items were analyzed for M demand (Pascual-Leone's developmental construct). Data on second- and third-grade subjects were analyzed for extent of absolute agreement of Raven and Figural Intersection Test (FIT) scores. Raw scores on the Raven could be deduced on the basis of FIT performance. (Author/RD)

In their reply to the present author's critique (1991), J. H. Kranzler and A. R. Jensen have still not demonstrated that a factor of general intelligence, "g," depends on, or contains, several independent factors. They have only demonstrated that an estimate of "g" is predictable from several independent components. (SLD)

Investigated validity of the Short Form Test of Academic Aptitude (SFTAA) as a predictor of Wechsler Intelligence Scale for Children-Revised (WISC-R) Full Scale IQ. Tested junior-high students and found the WISC-R could be estimated satisfactorily from the SFTAA, which was shown to be a valid indicator of intelligence. (Author/JAC)

Using the Matching Familiar Figures Test and the Porteus Maze Tests with characteristic modifications, the feasibility of using measures of cognitive tempo were examined. The measures' contributions in predicting the work performance of institutionalized moderately-severely retarded subjects were no greater than conventional individual…

Stochastic difference equations of the Box-Jenkins form provide an adequate family of models on which to base the stochastic theory of human growth processes, but conventional time series identification methods do not apply to available data sets. A method to identify structure and parameters of stochastic difference equation models of human…

During the last two decades of work in predicting and explaining school achievement, much research has emphasized the identification and measurement of student cognitive and affective processes which predict and also promise to help explain and facilitate school achievement. This review focuses on modifiable cognitive and affective processes, as…
