オンサイトにおける森林の視覚刺激の有無が主観的回復感・感情・注意回復力にもたらす影響

Abstract

In the on-site forest environment (the mixed forest of a Larch, Giant dogwood and Veitch fir), we set out our research purpose, which clarified the psychological healing effect of forest scenery as visual stimuli on respondents. With 15 male and female adult respondents respectively, we conducted a viewing experiment to investigate the affect, subjective restorative quality and degree of attention restoration using three types of research questionnaires. Consequently, in terms of affect, even though neither positive nor negative affect could be confirmed from statistical interaction when comparing opening and closing sessions (providing visual stimulus and covering respectively), there was a statistical decline (reduction) in the ‘before’ (pre-viewing experiment) compared to ‘after’ (post-viewing experiment). As for subjective restorative quality, interaction between opening-closing and ‘before’-‘after’ sessions was confirmed as well as individual statistical differences comparing ‘before’ and ‘after’ in the opening session and opening and closing sessions in ‘after’ session sequentially. Regarding the degree of attention restoration, subsequent results of opening-closing comparison clarified that the criteria of run away, fascination, scope and compatibility were statistically higher in the opening rather than closing session, and preferences showed a statistically higher score in the opening rather than closing session.
