Abstract
The purpose of this study was to clarify; 1) the psychological stress reduction effect (PSRE) that "sunshine filtering through foliage (SFTF)" brings visually, 2) the relation between the effect and the subjective appraisal (SA) of the forest environment otherwise the personality and other traits (PAOT), 3) the system of PAOT- SA- PSRE based on Lazarus’s acting stress model. We showed 2 images such as photos with and without SFTF in the forest as a simulation for 17 subjects, and examined the change in the psychological feelings (POMS; 3-times) by some indexes (PSRE and SA (SD Method; twice)) for each stimulation before and after the experiment in an artificial weather room. As a result, in comparison the presence of SFTF stimulation with the control, it was clarified that "Tension-Anxiety" and "Fatigue" significantly decreased with the control. In comparison the presence of SFTF stimulation with the other, "Vigor" was significantly higher than that of the absence of SFTF otherwise "Tension-Anxiety" was significantly lower. Furthermore, some evaluation indexes of the SA related to PARE received from the both of SFTF, and those evaluation indexes were affected by the respondents’ PAOT such as “Extraversion” and so on.
