Marked gender differences in three-dimensional mental rotation have been broadly reported in the literature in the last few decades. Various theoretical models and accounts were used to explain the observed differences. Within the framework of linking item design features of mental rotation tasks to cognitive component processes associated with…

A computerized adaptive test of word knowledge was administered over the telephone by reading items and response alternatives to 144 recent military enlistees who had completed the Armed Services Vocational Aptitude Battery. Correlations, factor loadings, and administration time indicate that the procedure is a good measure of crystallized verbal…

Several measures of the speed of information processing were related to ability factors derived from the Cattell-Horn theory of fluid and crystallized intelligence. Correlations among the ability measures, among the information processing measures, and between the two domains were analyzed using confirmatory factor analysis. (Author/PN)

The predictability of individual differences in the ability to reason about dynamic displays from tests using static displays was studied in 170 adults given paper-and-pencil and computer controlled tests. Several multivariate analyses indicated that the ability to reason about dynamic motion was distinct from the ability to reason about static…

Latent dimensions underlying individual differences in performance of information-processing tasks and dual task combinations, and the existence of a time-sharing (TS) ability were studied in 81 male college students. Supportive evidence for a general TS ability was not found. An identified TS factor specific to task combinations is discussed.…

Developed five knowledge tests and one implicit reasoning test designed to be short, correlated with cognitive aptitude, unobtrusive, and capable of administration in computer, e-mail, or paper-and-pencil forms. Administered these tests to 288 Air Force recruits and validated them against the Armed Services Vocational Aptitude Battery. Results…

Individual differences in performance on 4 computer-controlled visual memory and recognition tasks as a function of performance on 5 paper-and-pencil spatial tests were studied for 90 psychology students attending the University of Rennes (France). Results show that spatial thinking is partially supported by visual memory. (SLD)
