Psychological and physiological effects caused by the odor of wood in different Prefectures

Abstract

This paper outlines a study conducted to verify the psychological and physiological effects of the odor of wood in different prefectures. In this experiment, 9 healthy university students smelled 4 samples of cedar which grew in Miyazaki Prefecture, Gifu Prefecture, Mie Prefecture, and Mie Prefecture (these contained core materials). The psychological effects were studied by conducting a survey (by distributing questionnaires) to enquire about odor intensity and desirability. The physiological effects were determined by measuring the brain waves of the subjects. The study shows that the subjects exhibit differences based on their growing area and the core material’s characteristic tendency.
