美術心理學大師安海姆在Art and Visual Perception一書中，對於構圖平衡的要素提出若干原則，這些原理原則常被用於美術相關科系入學測驗及繪畫、設計、建築等相關領域，藝術教師亦於課堂上教授這些美的原理原則，但這些不斷被傳頌的「真理」真的是無庸置疑的嗎？研究者欲對此理論，以文獻探討及問卷調查法、圖片分析等方法進行分析與調查。另外，拉斐爾為西斯汀教堂所繪製的掛氈畫底稿及掛氈畫，兩者究竟是何者為拉斐爾最初製圖之原意，常為後人所爭論，因此研究者亦於本研究中，探求究竟觀者認為底稿與掛氈，何者較具有美感，以提供世人不同的思考角度。研究結果發現：安海姆與的主張未能在本研究中，獲得壓倒性的支持、且受試者對於底稿及掛氈畫，並無顯著偏好。

In Art and Visual Perception, Rudolf Arnheim said, “When two equal objects are shown in the left and right halves of the visual field, the one on the right looks larger. For them to appear equal the one on the left has to be increase in size.” This claim was supported by P. A. Oppe. Seen as “true”, the claim had since been applied to college entrance examinations and used as teaching material in the fields of painting, design and architecture, etc. The present researchers aimed to examine such claim and investigate its validity among present day Taiwanese respondents. Literature review, questionnaire and picture analysis were employed in the study. It was found that Arnheim’s particular observation was not strongly supported by the result of the present investigation.
