Abstract
Exposed 60 undergraduates to a randomized sequence of 58 3-dimensional geometric forms of various sizes and shapes. 20 Ss received visual exposure, 20 Ss received haptic exposure, and 20 Ss received joint visual and haptic exposure. 1/2 of the Ss in each of the 3 modality conditions were given a recognition test on each object concurrent with exposure to the object, while the remaining Ss were tested subsequent to object exposure. All recognition testing was conducted in the visual modality. Results indicate that Ss performed significantly better on the basis of visual and bimodal input than with haptic input exclusively. The imposition of a delay resulted in significantly poorer performance. A strong trend toward significance suggests that the effect of a delay is most pronounced with bimodal input.
