The Japanese word rizumu-kan is a common word that somewhat refers to an ability to perceive and recognize rhythm. It could also mean an ability to move rhythmically involving cognition. Although the word is widely used in scientific discourses, it has not been given a straightforward definition. This paper aimed to discuss what the word rizumu-kan encompasses for human cognition and behavior, especially for artistic physical expression in the field of cognitive science. First, we showed that the ambiguity of rizumu-kan comes from the fact that rhythm is ubiquitous on various spatiotemporal scales and that the definition of rhythm varies from one discipline to another. Second, we reviewed and classified scientific studies on rizumu-kan. Finally, to further understand rizumu-kan for artistic physical expression in cognitive science, we propose the following: (1) to put these studies in a broader context where the behavior is situated, and (2) to develop a mixed research method within the framework of ecological psychology while giving some caveats that should be considered in planning and designing such studies.

Musicians have to coordinate movements interpersonally to perform in an ensemble. As such, this study explores how violinists coordinate movements to play the same melody together in terms of the leader–follower relationships revealed by players’ movements. Twelve violinists participated in the study and played a violin ensemble in pairs. We applied Granger causality analysis to the three-dimensional displacement data of players’ heads, violins, and bows to identify leader–follower relationships between players. The results revealed the following: i) the participants adopted leader–follower roles during trials; ii) as the performance proceeded, the participants swapped roles; iii) the more difficult the parts of the score, the more notable the leader–follower relationships; iv) compared with between-head and between-violin data, the movements for between-bow data were more similar in more parts of the score that demonstrated leader–follower relationships. Further examination of cases where the leader–follower relationships were identified showed that players may have employed their own strategies to achieve a stable, coordinated state. These results suggest that, when the roles of players are not fixed in violin ensembles, performance can be adjusted in multiple ways, including swapping leader–follower roles, which is in stark contrast to previous studies that reported fixed leader–follower relationship when the first violinist only led the other parts in a string quartet.

緊張や不安を感じながらも大観衆の前で美しく踊るバレリーナには、どのような心理生理学的な反応が生じているのだろうか。これまでパフォーマンス不安による心理生理学的な反応は、主に実験室での模擬的な環境内で測定されてきており、実環境におけるパフォーマンス本番での測定は極めて少ない。また、パフォーマンス不安に関する研究は楽器演奏をする音楽家や低強度運動時のスポーツ選手を対象にしたものが多く、同様の結果が中から高強度で運動をする人にも当てはまるかどうかは不明である。そこで本研究ではパフォーマンス不安が、中から高強度運動時の心拍数にどのような影響を与えるのか検討した。実際の観衆(400名以上)の前で踊るプロのバレリーナ1名が、中から高強度の運動強度で踊っている最中のR-R間隔を心拍計により計測した。心拍数はR-R間隔より算出した。舞台上でのリハーサルと本番での心拍数を比較した。その結果、本番での最大心拍数は180拍/分を超えており、リハーサル時よりも本番中の方がおよそ10拍/分心拍数が高かった。これらの結果から、中から高強度運動時においても、パフォーマンス不安により心拍数が増加することが明らかになった。
