Abstract:
Visual characteristics (e.g., the color and shape) of ornamental plants can significantly affect their beneficial influence on humans. Prior research, however, has largely focused on the effects of the color or shape of flowers and the impact of differences in the visual appearance of foliage plants and plants with ornamental stalks has not yet been fully explored. This study examined the psychophysiological effects of urban ornamental bamboos that expressed different colors on different organs. Three hundred Chinese college students participated in the experiment. They were randomly assigned to view images of five ornamental bamboo landscapes with the following different visual characteristics: green stalks (GS) non-green stalks (NGS) multicolored stalks (MS) green leaves (GL) and multicolored leaves (ML). Before and after viewing the images, their EEG, blood pressure, pulse, profile of mood states (POMS) score, and state-trait anxiety inventory (STAI) score were measured. The results showed that ornamental bamboo landscapes have extremely significant beneficial psychophysiological effects as compared to urban landscapes. After viewing landscapes in the NGS and MS groups, EEG, blood pressure, and pulse rate of subjects showed more beneficial changes. Significant gender differences were observed only in systolic blood pressure and in the vigor score. In addition, an extremely significant interaction between color and organ of color expression was observed on systolic and diastolic blood pressure. Organ of expression had significant main effects on all the physiological indicators and the fatigue, vigor, and irritability scores, while color only had a main effect on systolic blood pressure. Our study concluded that viewing urban ornamental bamboo landscapes with different visual characteristics has different effects on humans. With regards to ornamental bamboo, the organ expressing the color had a greater impact on psychophysiological responses than did the type of color itself. These study results can provide guidance for landscape construction of urban greening.
摘要:
视觉特征(例如,观赏植物的颜色和形状)可以显着影响其对人类的有益影响。先前的研究,然而,主要集中在花的颜色或形状的影响,以及观叶植物和带有观赏茎的植物的视觉外观差异的影响尚未得到充分探索。这项研究考察了城市观赏竹子在不同器官上表现出不同颜色的心理生理作用。三百名中国大学生参加了这个实验。他们被随机分配观看具有以下不同视觉特征的五种观赏性竹林景观的图像:绿茎(GS)非绿茎(NGS)五彩茎(MS)绿叶(GL)和五彩叶(ML)。在查看图像之前和之后,他们的脑电图,血压,脉搏,情绪状态(POMS)评分,并测量状态-特质焦虑量表(STAI)评分。结果表明,与城市景观相比,观赏竹景观具有极其显著的心理生理效应。在NGS和MS组中查看风景后,脑电图,血压,受试者的脉搏率表现出更有益的变化。仅在收缩压和活力评分中观察到显着的性别差异。此外,在收缩压和舒张压上观察到颜色与器官颜色表达之间的极显著相互作用。器官的表达对各生理指标和疲劳,活力,和烦躁的分数,而颜色仅对收缩压有主要影响。我们的研究得出结论,观看具有不同视觉特征的城市观赏竹景观对人类的影响不同。关于观赏竹,与颜色类型本身相比,表达颜色的器官对心理生理反应的影响更大。研究结果可为城市绿化景观建设提供指导。
