Effect of form and location of a shading on apparent depth of subjective contour letters シュカンテキ リンカク モジ ノ ミエ ノ オクユキ ニ オヨボス インエイ ノ ケイタイ ト イチ ノ コウカ 主観的輪郭文字の見えの奥行きに及ぼす陰影の形態と位置の効果 Liu, Wei 153100 劉, 威 153099 141.27 陰影 主観的輪郭文字 立体感 奥行き 形態要素数 application/pdf 論文(Article) Two experiments were performed to examine how apparent depth of a subjective contour letter is affected by location and form of shading attatched to the letter. Twenty participants rated a list of letters with shading in various (bottom, lower left, left, upper left, top, upper right, right, and lower right) according to apparent depth in Experiment 1, while 56 participants rated letters consisted of lines varying in symmetry in Experiment 2. Experiment 1 showed that the rating of apparent depth was higher with the letters shaded in positions diagonal to the letter than in vertical or horizontal position. Experiment 2 reproduced the effect of the position of shading obtained in Experiment 1, and showed that the rating was different between the letters reversed vertically. The rating of form for each letters were compatible with that of the apparent depth in both experiments. The results indicate that apparent depth is affected by position and form of a shading. departmental bulletin paper 熊本大学 2011-03-25 VoR application/pdf 熊本大学社会文化研究 9 281 291 1348530X AA11837081 https://kumadai.repo.nii.ac.jp/record/24884/files/SB0009_281-291.pdf http://hdl.handle.net/2298/20080 https://kumadai.repo.nii.ac.jp/records/24884 jpn
