The effect of location of a highlight in a shaded circle on depth perception オクユキ チカク ニ オヨボス インエイ ノ ハイライト ノ イチ ノ コウカ 奥行き知覚に及ぼす陰影のハイライトの位置の効果 井上, 浩義 153210 イノウエ, ヒロヨシ Inoue, Hiroyoshi Watanabe, Isao 104748 井上, 浩義 104743 渡辺, 功 104744 140 visual depth perception shading location of highlight application/pdf 論文(Article) Two experiments were perfbrmed to examine how the apparent depth of a shaded circle on a plane was affected by the direction and the distance of a highlight in the shaded area from the center of the circle. Fourteen undergraduates were asked to rate the concentrically shaded circle according to the apparent depth using the method of magnitude estimation. Experiment 1 showed that the rating was the highest in the upper-left, upper-right, and top conditions of the direction and the lowest in the bottom condition. Experiment 2 showed that the rating was the highest when the highlight was located at a third of the diameter of the circle apart from the center and the lowest when the hightlight was on the edge of the circle or in the center. On the whole, the results support Ramachandran's ゜Assumption of Light From Above" which states that humans perceive a circle shaded bright in the top and dark in the bottom as convex due to their long experience on the earth since their birth. journal article 社団法人日本心理学会 2005 VoR application/pdf 心理学研究 1 76 51 56 AN00123620 https://kumadai.repo.nii.ac.jp/record/23813/files/jpr76_1_51-56.pdf http://hdl.handle.net/2298/15751 https://kumadai.repo.nii.ac.jp/records/23813 jpn 00215236
