Allowing respondents to retake a cognitive ability test has shown to increase their test scores. Several theoretical models have been proposed to explain this effect, which make distinct assumptions regarding the measurement invariance of psychometric tests across test administration sessions with regard to narrower cognitive abilities and general…

Dynamic testing is an assessment method in which training is incorporated into the procedure with the aim of gauging cognitive potential. Large individual differences are present in children's ability to profit from training in analogical reasoning. The aim of this experiment was to investigate sources of these differences on a dynamic test of…

Here we reprint, and provide background and a commentary on, a recently-rediscovered lecture by Godfrey H. Thomson entitled, "Intelligence and civilisation." It was delivered at the University of Manchester, UK, on 23rd October, 1936, printed in 1937 in the short-lived "Journal of the University of Manchester" and as a pamphlet…

Mean gain scores for cognitive ability tests between two sessions in a selection setting are now a robust finding, yet not fully understood. Many authors do not attribute such gain scores to an increase in the target abilities. Our approach consists of testing a longitudinal SEM model suitable to this view. We propose to model the scores' changes…

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…

Five major trends in the study of intellectual abilities are identified. These suggest that in the future several kinds of tests will be used to measure several kinds of basic processes of intelligence. There will be a corresponding decrease in concern to measure a single attribute of general intelligence. (Author/RD)

By comparing the profile of "g" loadings for a set of psychometric test scores, it is shown that general intelligence is related to timed performance measures from perceptual-motor tasks, more strongly on more complex tasks. The profile of the "g" loadings was predictable from the response-time (RT) psychometric test time correlations for four RT…

This editorial suggests how the approaches of differential psychology and information processing psychology should be combined to study intelligence. Methods reviewed include factor analysis, componential analysis, and computer simulation. Guidelines for the specification of subtheories of intelligence, as well as future theories and methods for…

Dynamic assessment procedures involving either verbalization or elaborated feedback lead to higher levels of Ravens Matrices performance, modified visual search behaviors, reduced test anxiety, and reduced negative orientations to the testing situation in third graders. Results are interpreted on offering construct validation to the assessment…

Intelligence tests are likely to move toward measuring multiple aspects of ability. Tasks will be less abstract and closer to life experiences of the individual. The metric will change from the present formula to a separate score for each measured ability, normed in relation to cultural and linguistic background. (Author/RD)

Various testing-the-limits procedures were employed in administering the Raven Coloured Progressive Matrices Test to second- and fourth-grade children. Tests of impulsivity, neuroticism, extroversion, intelligence, and achievement were given. Procedures which involved verbalization and feedback were efficacious in maximizing performance on the…
