Impression on biophilic designs influences the effects of indoor greening. The current study aimed to investigate the effects of different biophilic designs in office rooms on the psychological and physiological responses and the cognitive performance of office workers. Indoor greening rooms with Japanese and tropical designs were used along with the green-free (control) design in this study. The heart rate variability of the participants was not affected by green designs. However, there was improvement in impressions on tropical and Japanese designs in office rooms. In particular, the Japanese design was more effective in decreasing negative emotions than the tropical design. The electroencephalography during 5-min exposure to the greening designs showed limited frequency bands and regions of interest affected by the greenery design. Taken together with the psychological data, indoor greening with the tropical design promoted positive mood states. Meanwhile, indoor greening in the Japanese design, inhibited negative mood states. However, there were no significant differences between the two designs in terms of cognitive task performance. Hence, indoor greening increases neural efficiency during cognitive tasks.
对仿生设计的印象会影响室内绿化的效果。本研究旨在探讨办公室中不同的仿生设计对办公人员心理和生理反应以及认知表现的影响。本研究使用了日式和热带设计的绿化房间以及无绿化（对照）设计。参与者的心率变异性不受绿化设计的影响。然而，办公室中对热带和日式设计的印象有所改善。特别是，日式设计比热带设计更能有效减少负面情绪。在 5 分钟暴露于绿化设计的脑电图显示，受绿化设计影响的有限频带和感兴趣区域。结合心理数据，热带设计的室内绿化促进了积极的情绪状态。同时，日式设计的室内绿化抑制了负面情绪状态。然而，在认知任务表现方面，两种设计之间没有显著差异。因此，室内绿化在认知任务期间增加了神经效率。
