本研究運用重疊原理中的遮蔽效應,以「色彩」為主要引導要素,使兩圖形經過「透明重疊」(透疊)後,產生視覺深度(前後)線索判斷的錯覺。本研究並針對無彩度及有彩度兩階段的實驗,透過透疊感覺的樣本設計,使不同的色彩變化,讓受試者產生對正方形與圓形兩者的前後關係之知覺判斷。研究結果發現,學習背景及性別在重疊圖形的前後判斷中並無明顯差異,位置的改變會產生不同的視覺觀感,觀看者的視覺焦點及注意力也會產生不同的知覺,色彩明度的改變,更是傳達圖形距離感與深度感的重要特徵。對於線性的重疊圖形都有「圓形在前」的認知,但隨著兩個形體的分離也使受試者的判斷改變,有部份受試者對圖形的前後知覺判斷,受到繪畫中的「高遠低近」、「高後低前」、「前清楚、遠模糊」及「前色深、遠色淺」等理論影響,另一部份受試者的前後知覺判斷,則受到色彩理論中的「暖色在前,寒色在後」之理論影響,及受到完形心理學的理論影響知覺的判斷。
In this study, the illusion resulting from overlapping figures under different colors are studied. The experimental results show that the learning background and sex are not important factors in the front-back judgement of overlapping figures. However, the position of figures, the people's attention and the colors of figures are important factors in judging distances and depth of figures. In general, the circular figures look front, the higher figures look far and back, and the front figures look clear and with dark and warmful colors. In addition, some of the experiment results in people's perception judgements are consistent with the Principle of Gestalt Psychology.
