The Psychological evaluation measured at three time points, was before exposure to the wood environment (T1), 45 minutes after exposure to the wood environment (T2), and 20 hours after exposure to the wood environment (T3).

Results : As a result of examining the effect of the wood interior use ratio on psychological variables, After about 20 hours (T3), there were significant differences in mood state_vigor-activity(χ² =7.253, p<0.05), mood state_tension-anxiety (χ² =7.041, p<0.05), mood state_anger-hostility(χ² =8.318, p<0.05), and state anxiety (χ² =7.680, p<0.05). State anxiety also showed a significant difference in T2 (χ² =8.811, p<.05). As a result of analyzing the effect on satisfaction and subjective impression, there was a significant difference in satisfaction (χ² =6.300, p<0.05) and ‘pleasant (χ² =6.930, p<0.05), airy (χ² =6.628, p<0.05), masculine (χ² =6.906, p<0.05), ordinary(χ² =6.662, p<0.05), natural (χ² =13.924, p<0.001), calm (χ² =13.106, p<0.001), safe (χ² =7.755, p<0.05)’.
