    Abstract: 平衡性是產生美感的重要因素,然而對於平衡性的界定與量測却未有定論,以實徵取向探討平衡性之影響美感的研究亦不多。本計畫以Wilson與Chatterjee(2005)的八種分項平衡指標為基礎,提出垂直、水平或對角軸的兩側平衡,與重心概念之平衡較為有關,而內部與外部區域之平衡,乃與均勻度有關,兩者皆影響美感;並且對角軸平衡的動態性高於垂直水平軸,亦有助於產生較高的美感,而此一因素可能與體現模擬有關,涉及鏡像神經系統之活動,可用mu節律作為指標。針對以上的假設,以幾何圖像為材料,設計三個實驗加以驗證。實驗一探討不同軸兩側平衡對於美感的影響,檢驗對角軸平衡是否產生較高的美感;實驗二探討均勻性對於美感的影響,亦再驗對角軸平衡之提升美感;實驗三則操弄對角軸平衡性、垂直水平軸平衡性以及均勻性,進行EEG記錄以獲得mu節律資料,藉以驗證對角軸之動態性透過鏡像神經系統產生影響之假設。綜合三個實驗所得結果,對角軸高度平衡所得美感高於垂直水平軸高度平衡之美感,高度的平衡性與均勻性兩者皆有助於產生較高的美感,支持本研究對於平衡性、均勻性與動態性之影響美感所提出的假設。然而mu節律所得結果,未能支持鏡像神經系統為幾何圖像動態性之產生美感的主要神經生理機制,有待後續研究繼續加以探討。
    In the aesthetic literature, balance is very important for the artistic appreciation. But the definition or
    measurement of the balance is not clear. In this project, based on the eight indices for balance given by Wilson and Chatterjee (2005), some hypotheses were proposed. The bilateral balance relative to the vertical, horizontal, or diagonal axis may be almost the same as the balance around the center of mass. In contrast, the balance between the inner and outer regions of the image may be more close to the concept of homogeneity. Both the balance and homogeneity will contribute independently to the aesthetic value of the images. Moreover, the balance relative to the diagonal axis has higher degree of dynamics than the vertical or horizontal axis and therefore more beautiful. We further propose that dynamics may affect the aesthetic experience through the embodied simulation relevant to the function of the mirror neuron system. Therefore, mu rhythm which can reflect the activity of mirror neurons would be an appropriate measure to verify our hypotheses. Three experiments were designed for this project using geometrical images as the material. Experiment 1 investigates the effects of the balance with respect to the different axis (or axes) on the aesthetic judgment. Experiment 2 investigates the effects of homogeneity (and also axes of balance) on the aesthetic judgment. Manipulating all three factors (i.e., balance, homogeneity, and dynamics) in Experiment 3, we use mu rhythm as a measure to validate the involvement of the mirror neuron system for aesthetic processing of dynamics. The results of the first two experiments showed that the balance for two diagonal axes can have higher effect to increase aesthetic scores than the balance for vertical and horizontal axes. Therefore, the importance of the dynamics of images for aesthetic appreciation was supported. Also the effects of balance and homogeneity on aesthetics were supported in experiment 2. But the results of the mu rhythm in
    experiment 3 did not validate the mirror neuron system as the mechanism of the aesthetic appreciation based on the dynamics of the images. Further studies will be needed for exploring the neural mechanisms for the aesthetic appreciation of the dynamics.
