きめのレーシネスに及ぼす速度と距離の効果  [in Japanese] Effects of speed and distance on texture laciness  [in Japanese]

We examined how moving speed and distance between two textures affect texture laciness, a phenomenon, in which one texture is often seen through the other when the textures are presented overlapped. Fifteen undergraduates and graduates were asked to rate the laciness and apparent depth between the textures. Experiment 1 showed that texture laciness and apparent depth increased with increasing speed. Experiment 2 showed that texture laciness and apparent depth increased with increasing moving distance between the textures. Experiment 3 showed that texture laciness decreased in a condition where moving speed appears remarkably fast. Experiment 1 and 3 showed that speed affected sharply texture laciness only when it was slow. Therefore, we conclude that there is an appropriate speed to produce texture laciness.
