圖形對稱性之情緒與生理反應分析
中文摘要
喚起恐懼感的造形特徵為何，過往研究發現角形輪廓與非對稱的造形會讓人感到不安全或恐懼，而弧形和對稱圖形會讓人感到愉悅與安全。本研究設計一套不同輪廓變化與對稱性的圖形進行驗證，實驗方法以生理訊號量測為主、量表評量為輔來數據化情緒感受，探究觀看非對稱或角形圖形時，是否會讓人感到不愉快、低安全感或呈現恐懼感的生理訊號如：心跳速率上升、皮膚電位上升與末梢指端溫度下降。實驗圖形以對稱性和輪廓變項為自變項，前者有三個水準：弧形輪廓、角形輪廓和介於兩者間的混合輪廓，後者有對稱和非對稱兩種水準，依變項為愉悅度、安全度評量和心跳速率、皮膚電位與末梢指端溫度。結果顯示，對稱和弧形輪廓都是能增加愉悅度與安全度的顯著獨立因素，其中愉悅度以對稱影響力最大，而安全度則是輪廓變化最顯著。造形變化與恐懼度之生理訊號未有顯著的交互作用或影響效果，但呈現出恐懼度的圖形多為非對稱和角形輪廓圖形。就本研究而言，整體造形變項未有顯著效果，但單一圖形的反應來看，非對稱和角形輪廓是能喚起恐懼感的造形特徵與生理訊號。
Abstract
Previous studies have presented people prefer an object composed of curved contour or symmetry much than which with angular contours or asymmetry are associated with unsafe. By using symmetrical graphics with variable contours including three levels: curved, mix and angled as stimuli, we recorded physiological recordings of ECG GSR and FT, combining with Likert scale surveying, to observe possible interactions between graphical symmetry and physiological signals. Integrated five variables showed that the level of scale, curved contours make people feel pleasure and safe, angular contours make people feel less pleasure, mixed contour make people feel less safe. No significant difference in physiological signals with all symmetry and variable of contours. But as the each data of every graphic, we generalize that the elements being connected with fear physiological signals are asymmetrical and angled elements.
