Expression of emotions in dance: Relation between arm movement characteristics and emotion

This study was designed to investigate the relations between emotional expression and the movement characteristics. For this purpose, we used kinematic data related to three factors of the movement characteristics: Speed, Force, and Directness. In Exp. 1, we examined how the dancers expressed emotions when they used a certain body action and body part, and how they altered the movement characteristics. In Exp. 1, 10 female dancers were instructed to express three emotions, joy, sadness, and anger, by altering arm-movement characteristics. Analysis of variance indicated that the three exhibited emotional expressions had different movement characteristics. Discriminant analysis indicated that kinematic data for evaluation of movement characteristics are useful for discrimination of the three emotional expressions in dance. In Exp. 2, we investigated how naive observers perceived the type of emotion from the arm-movement characteristics. Analysis of variance showed that 22 observers accurately perceived each emotion distinguished from other emotions. Multiple regression analysis showed that specific movement characteristics influenced the perception of particular emotion.
