Experiment 1 showed that the ratio of luminance between background and shaded circle didn't affect, the apparent depth perception in circular gradation condition. It is because that the shaded circle with circular gradation tended to be perceived as a sphere. Experiment 2 and 3 showed that, the shaded background affected apparent depth perception whatever gradation condition is linear or circular. The background shading promotes concave perception when the highlight was located at the top, and promotes convex perception when the highlight was located at the bottom. The results suggest that background's depth is strong cue to apparent depth perception from shading.}, pages = {35--43}, title = {陰影による奥行き知覚に及ぼす背景の輝度と陰影の効果}, volume = {7}, year = {2009}, yomi = {イノウエ, ヒロヨシ and イノウエ, ヒロヨシ} }
