A factorial and predictive study of spatial abilities

Abstract Seven tests of spatial abilities were administered to 163 first year engineering students at the University of Melbourne. Academic selection (quota) scores and criterion measures in the form of final exam marks and scores on other work in engineering drawing were also obtained. A factor analysis of these measures yielded three main factors: I Academic performance, II Visualization and manipulation of images, and III Scanning and pathfinding. The results suggest that although visualization is not used in current selection procedures, it is an important factor in academic success in first year engineering.
