Compares results of Successive Perception Test I (SPT) for the study population of freshman engineering students to their results on the group-administered Purdue Spatial Visualization Test: Visualization of Rotations (PSVT) and the individually administered Haptic Visual Discrimination Test (HVDT). Concludes that either visual and haptic abilities are not mutually exclusive, or the SPT score classifications of visual and haptic tendency are not appropriate for the population of freshman engineering students.
