Research Abstract

I conducted the following two studies on tactile material perception. (1) We compared the psychophysical patterns of roughness perception and unpleasantness. The psychophysical functions were between the two percepts were highly similar, whereas the constancy of roughness to motion was greater than that of unpleasantness. (2) We investigated brain activity during detecting congruency/incongruency of materials presented visually and haptically. We found that neural substrates revealing the congruency/incongruency effect during perception of materials were different from those during perception of spatial properties of an object (e.g., orientation).
