Abstract
We experience the shape of objects in our world largely by way of our vision and touch but the availability and integration of information between the senses remains an open question. The research presented in this article examines the effect of stimulus complexity on visual, haptic and crossmodal discrimination. Using sculpted three-dimensional objects whose features vary systematically, we perform a series of three experiments to determine perceptual equivalence as a function of complexity. Two unimodal experiments--vision and touch-only, and one crossmodal experiment investigating the availability of information across the senses, were performed. We find that, for the class of stimuli used, subjects were able to visually discriminate them reliably across the entire range of complexity, while the experiments involving haptic information show a marked decrease in performance as the objects become more complex. Performance in the crossmodal condition appears to be constrained by the limits of the subjects' haptic representation, but the combination of the two sources of information is of some benefit over vision alone when comparing the simpler, low-frequency stimuli. This result shows that there is crossmodal transfer, and therefore perceptual equivalency, but that this transfer is limited by the object's complexity.
