COGNITIVE SCIENCE ON HORTICULTURAL THERAPY

通过认知科学的方法研究植物的治疗作用及其生长活动。通过对老年人日常生活的调查，明确了园艺活动对生活质量的积极影响，但作为一种园艺治疗方案，相关机构还需要进行基础研究。利用脑电图、心率变异性和情绪分析对植物生长活动的影响进行了实验研究。α节奏和积极情绪随活动的增加而增加，而不随活动的进行而增加。然后，比较操场上有草坪和裸露地面的小学学生对日常环境中常见植物和昆虫的认知度。而且，植物和昆虫的识别能力在两者之间存在显著差异。然后，通过对小学生从事水田耕作活动的行为和话语进行分析，阐明活动在自然中的作用，话语从感叹、感性、感性的印象转变为观察、温柔的感受。因此，明确了园艺活动首先给人以感官和情感上的印象，然后根据植物的生理心理效应及其生长特点，通过园艺活动增强观赏性和亲切感。

The healing effects of plants and of its growing activities are investigated through cognition scientific methods. Horticultural activities are clarified to have positive effects on the quality of life based on the investigations of daily life of aged people, but as a program for horticultural therapy the fundamental researches are desired in related institutions. The effects of plant growing activities are experimentally investigated using EEG, heart rate variability and emotional analysis. And, alpha rhythm and positive emotion are inclined to increase with the activities comparing with just inspecting the resulted situation without activities. Then, the recognition of popular plants and insects in daily environment was compared between pupils of elementally schools with playground covered by lawn and with bare ground. And, the identifying ability of plants and insects significantly differed between the two. Then, the behavior and utterance of pupil engaged in paddy field farming activities were analyzed to clarify the effects of activities in nature, and the utterance have changed from exclamation, sensuous and emotional impressions to observation and a tender feeling. Consequently, it was clarified that horticultural activities bring sensuous and emotional impressions at first, then enhance observation and a tender feeling based on the physio-psychological effects of plant and its growing characteristics with horticultural activities.
