不同景觀型態對注意力之影響

Abstract

許多研究指出，接觸自然環境可以對人類生理及心理產生許多益處，其中一種為恢復勞動與壓力所產生的心理疲勞，藉此提升注意力。本研究欲探討人工與自然景觀對人類注意力產生的助益或耗損，進一步瞭解觀看自然景觀時，環境中「綠視率的高低」、「植栽顏色的多寡」、「植栽種類的多寡」、「有無水景」四種構成要素，對於注意力表現上有何影響。 本研究利用NCPC（Necker Cube Pattern Control）注意力測驗，檢測受測者觀看60張景觀圖片之前與之後翻轉次數的改變，用此評估各環境變項對受測者注意力的影響。七個團體分別觀看其中一種圖片，分別為：1.人工景觀；2.自然景觀；3.高綠視率景觀（和植栽種類多樣、綠色植栽、無水景景觀合併成一組）；4.低綠視率景觀；5.單一植栽種類景觀；6.彩色植栽景觀；7.有水景景觀之圖片。 結果顯示觀看自然景觀圖片後，受測者注意力表現顯著高於人工圖片，顯示自然環境對於人類的注意力，確實有正面的影響。將自然景觀依環境要素分項探討，結果顯示除了單一植栽種類及低綠視率對於注意力表現有降低的趨勢，彩色植栽對注意力表現沒影響外，其他項對注意力表現皆呈現上升，又以水景對注意力的提升效果最為顯著，且植栽種類多樣環境對注意力的表現顯著高於單一植栽種類環境。 由以上結果可知，觀看自然景觀有助於注意力的提升，且自然景觀要素中，以植栽種類、水景對注意力表現的影響較大。建議景觀設計者從事景觀設計規劃時，可多設計此類型的景觀環境，不僅能美化環境，同時還可對人類的注意力有所助益。

Many studies indicated that when human beings exposed to natural environments, they could get rid of psychology fatigue about working and pressure, and then had more ability to focus attention. The purpose of this study is to figure out that how human beings’ attention will be affected by the artificial and the natural landscapes. And then the examination is going to focus on the performance brought from the four elements, including the visual percepted greening ratio, the types of plants , the kinds of color (the green plants v.s. the colorful plants), the environment with waterscape or not when subjects view natural landscape. Subjects were tested how they were concentrative by viewing 60 pictures of landscape and were evaluated by Necker Cube Pattern Control (NCPC) test. During testing, they have a pretest and a posttest. We discuss how the four important elements will influence people’s attention. In the examinations, different sets of pictures were offered: 1. the artificial; 2.the natural; 3. the high visual percepted greening ratio (the multiple plants, the green plants, the environment without waterscape); 4. the low visual percepted greening ratio; 5. the unitary plant; 6. the colorful plants; 7. the environment with waterscape. According to the report, significantly, we found that the subjects who looked at natural landscape pictures were more concentrative than the others who viewed the artificial pictures. It showed that natural environment really has positive influence on human. We discussed the elements of natural landscape. The result showed that the performance on the test about attention declined from pretest to posttest in the case of the environment with unitary plant, low visual percepted greening ratio. But the performance maintained the same quality in the environment of colorful plants. And the other performance improved. When it comes to the case with good performance, the subjects viewing waterscape improved significantly. Otherwise, the group of the multiple plants performed better than the one of unitary plant. In sum, viewing natural landscape pictures contribute to the improvement of attention. The two elements, the types of plants and the environment with waterscape or not, will have more influence on attention. It is a suggestion for landscape designers to keep the point when they have plans about landscaping. In this way, they could not only beautify environment but also bestead human’s attention.
