Many Flynn effect (FE) studies compare scores across different editions of Wechsler's IQ tests. When construct changes are introduced by the test developers in the new edition, however, the presumed generational effects are difficult to untangle from changes due to test content. To remove this confound, we use the same edition of Wechsler…

In recent years, models of giftedness have incorporated personal and social variables which influence IQ, rather than taking IQ into account exclusively. Among the various options presented in this context, authors have proposed dynamic assessment techniques as a method for revealing the potential capacity in different groups, independently of the…

Examined the validity of a subtest combination as an estimate of the Wechsler Intelligence Scale For Children (Revised) Full Scale IQ. Satisfactory correlations were found between the short and full scale IQ. The short form did not allow precise IQ estimation but shows promise as a screening device. (Author)

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…

Examined the relationships of reading and math achievement with intelligence and adaptive behavior in Anglo, Black, and Mexican American children (N=345). The variance accounted for by the full model (race, sex, age, and socioeconomic status) was significant for reading and math. Variance associated with race and socioeconomic status was…

The predictive validity and utility of assessment procedures can be increased by adding predictors to the prediction supplied by general ability tests. Of Jensen's early work comes the suggestion of focusing on the cognitive ability short-term memory (STM), especially for low-"g" Black children. Meta-analysis convincingly shows high…

Evaluated the Wechsler Intelligence Scale for Children-Revised (WISC-R) as a tool for understanding children's learning problems. Analyzed the predictive utility of several WISC-R subtest recategorizations with regard to academic achievement for 105 children referred for psychoeducational evaluation because of classroom learning problems. Stepwise…

Reviews findings on the predictive validity of psychometric tests of intelligence. Concludes that conventional tests of intelligence can be useful but only if they are interpreted very carefully, taking into account the factors that can affect them, and in conjunction with other measures. (Author)

The problems associated with the transition from the secondary level to the tertiary level in education have given rise to many surveys, analyses of statistics, research projects, reports and literature reviews. Much has been written on topics such as testing, selection, prediction and wastage, with findings and conclusions which appear to have…

The relationship between general cognitive ability and both training and job performance is reviewed. Existing scientific data show that there are large differences in training achievement and in job performance. Consequently, any good predictor of achievement or performance can yield a large gain in workforce productivity. General cognitive…
