Presented rectangular stimuli successively in pairs, either visually or haptically to 70 undergraduates. "Same-different" judgments were made in regard to their proportions. Unrestricted haptic inspection was only slightly inferior to visual, while restricting haptic inspection to a particular method of touch resulted in consistently inferior performance. Differences between groups were not statistically significant. Accuracy of judgment varied with the proportions of the standard stimulus, with differences between standard and comparison stimuli on several measures, and with the order of stimulus presentation. These variables were all highly significant. (PsycINFO Database Record (c) 2006 APA, all rights reserved).
