Abstract
An analytic schema is presented for decomposing the traditional global accuracy score from the Rod-and-Frame Test into a set of component scores. As a preliminary comparison of the usefulness of these component scores with the traditional composite measure, the data from a study by Hettema (1968) were re-analyzed. A sample of 70 male subjects was used to investigate the linear and nonlinear relationships between 22 RFT scores and scores from the Street Gestalt, Gottschaldt Hidden Figures, PMA Spatial, Hidden Pictures, PMA Reasoning, Muller-Lyer Illusions, Poggendorff Illusions, Peripheral Span, Squares , and Verbal Analogies tests . The RFT global accuracy score was not significantly related to any of these measures. In contrast, an intriguing pattern of significant relationships emerged between various RFT component scores and most of the cognitive and perceptual tests.
