Abstract
The purpose of this research was to investigate an attention restorative effect in the short-term staying of the on-site forest environment, using PRS based on an attention restoration theory (ART). Participants were 45-male-university students in their early twenties. The city environments where were the daily living environment were chosen as the control for experiments and in which the same experiment of the forest environments were conducted by the same schedule. To cancel an order effect, participants were divided into two groups and both groups were taken to the both environment to experience each of them during two days. After an experience in the each environment was finished, participants were asked to answer to PRS questionnaire. As a result, the appraisal of "Preference" for the forest environment was significantly higher than for the city environment on the contrary to that of "Familiarity". Then, the score of the indexes ("Being away", "Fascination", "Scope", "Compatibility") derived from ART after the experience of the forest environment was significantly higher than that of city environment. Consequently, there was psychological restorative effect in forest environment comparatively, from the viewpoint of ART and their traits were confirmed.
