動きの「キレ」の印象形成に影響を及ぼす要因の検討

抄録

The impression of sharpness of body movements (Kire in Japanese) is critical for aesthetical evaluation of body movements in dance, gymnastics, and martial arts’ Kata. However, the basis of impression formation of sharpness has not been empirically investigated to date. This study was designed to clarify how body movements’ speed affected impression formation regarding body movements’ sharpness. We also examined the effects of unexpectedly fast body movements on impressions of sharpness. Participants rated the impressions of sharpness, subjective speed, and unexpectedness of body movements when viewing movies of Karate Kata performance. Multiple regression analysis and path analysis revealed that subjective speed and unexpectedness affected impressions of sharpness of body movements and that subjective speed also affected them through unexpectedness. These results suggest that manipulating the speed and unexpectedness of movements effectively enhances impressions regarding the sharpness of body movements.
