Abstract
We conducted an experiment to investigate the relationship between dynamic changes in the angle and shadow of Noh mask and perceived emotions. We used koomote which is a type of female mask and is the most popular among Noh masks. A factor analysis extracted two factors of “positive emotions” and “negative emotions.” The results also revealed that dynamic changes in the angle and shadow should have strong effects on the perception of emotions in facial expressions for Noh mask and that the effects were stronger both when the face with positive emotions changed into the face with negative emotions and when the face with negative emotions changed into the face with positive emotions.
