寫實繪畫行為的認知與動作分析

Abstract

本研究嘗試透過實徵方式，探討認知過程中的平面空間定位準確性和與動作相關的手眼協調能力與寫實繪畫能力之間的關係。研究中將平面空間定位能力區分為絕對定位和相對定位能力，觀察此三者與忠實繪畫彼此間的關係。我們定義「絕對定位能力」為：僅僅參照單一的參考框架，而能準確判斷目標平面空間位置的能力，此單一的參考框架不與圖像產生群化作用；「相對定位能力」則是指依賴圖像本身部件與部件之間的空間關係去判斷某一部件位置的能力。

分析結果顯示忠實繪畫能力和本研究所定義的相對定位、絕對定位及手眼協調能力皆有關。推論相對空間能力可能和線條描繪的忠實程度有正相關。此外，相對定位能力和手眼協調轉化速度之間有正相關性，也和絕對定位有顯著正相關。藉由問卷得到受試者們繪畫經驗的資料並加以量化，分析後發現與相對定位和手眼協調能力有顯著正相關，也許這兩個能力皆可藉由繪畫加以訓練。

In this study, we investigated the relationship among the following aptitudes: 2-D spatial localizations, eye-hand coordination, and realistic drawing abilities. We differentiated the 2-D localization abilities into “absolute localization” and “relative localization”. “Absolute localization” means localizing the position of an element of an image with reference to a single frame that has no grouping effect with any part of the image. As to “relative localization”, it refers to localize an element of an image with reference to other parts of the image.

The result of this study reveals that realistic drawing abilities positively correlate with all three aptitudes that we tapped, i.e. absolute, relative localization accuracies, and eye-hand coordination performance. Relative localization is also found to correlate with both absolute localization and eye-hand coordination. The amount of prior training in drawing of the participants was evaluated quantitatively with a questionare. We find eye-hand coordination performance and relative localization accuracy might be enriched through drawing training as these two scores are correlated with the training level.
