高齡者隨著年齡的增加，在視覺上對於圖形、顏色、物體等的辦識及理解能力會跟著下降，導致認知差異的產生，而此現象的差異可能與個人生、心理條件與行為生活型態有關。本研究以各種長寬不同的矩形為對象，探討高齡者的基本條件、生活型態與圖形形狀的心理偏好差異，研究量表分成「基本資料」、「生活型態」、「形狀」三大項，並進行受測者對圖形之「喜歡」、「美感」、「舒服」等的偏好量測。經由交叉分析結果顯示：（1）在五種圖形形狀的偏好調查中，圖E的偏好度最低，圖B的偏好度最高，圖A的看法分岐最大。（2）兩兩配對與排序法的調查中，在「美感」的部分完全一致，「喜歡」與「舒服」較不一致，但對最不偏好的，則完全一致。（3）交叉分析的結果，有顯著差異者以圖A最多，其餘皆差異不大。本研究希望能初步了解高齡者的個人基本條件、生活型態與對不同形狀的認知是否具有關連性，提供給高齡者福祉設計相關領域及高齡者心理或生理治療的參考。

With the increasing of age, the visual acuity decreases of elderly. Their different perception of shape, color and image leads to cognitive differences. However, the physical decline in elderly may have individual differences; it may relate to personal psychological situation, behavior and lifestyle. Therefore, the purpose of the research is to explore the elderly's shape preference of the image with different ratio of length and width and their life styles. A survey was composed with three parts of questions: demographics, life style measurement scale and measurement scale of shape preference. Following three different scales were applied to measure their perception of shape: joyful, aesthetic and comfortable. Results revealed that (1) image (E) with the ratio of length and width is 1:1.8 was least preferred; elderly preferred image (B) with the ratio of length and width is 1:1.2; (2) with the least preferred shape, there is no significant difference between paired comparison method and selection sort method of measuring scales of joyful, aesthetic and comfortable; (3) elderly who preferred image (A) with the ratio of length and width is 1:1 possessed diverse background. This research provides preliminary understanding of the elderly in their shape perception, psychological and physical situation. Conclusions can be references for relevant future study and for medical treatment in psychology or physiology.
