Abstract: Quantitative Concepts and WRAT-3: Arithmetic evaluated mathematics-concepts. WCJ-III: Number Series evaluated number comprehension.An exploratory factor analysis of a battery of 16 measures of spatial ability identified three factors of visual perception: Perceptual Speed, Visualization, and Speed of Closure.Visualization was a significant predictor across all achievement measures-with the exception of WCJ-III: Numbers Series.After controlling for general intelligence, Perceptual Speed accounted for unique variance when predicting SAT Mathematics and WRAT-3: Arithmetic; Visualization accounted for unique variance when predicting SAT Mathematics and WCJ-III: Applied Problems; and Speed of Closure accounted for unique variance when predicting SAT Combined and SAT Critical Reading.Additional research will be needed to gain a full understanding of the implications of these findings.
