本研究的目的是更好地了解舞者如何通过舞蹈建立与音乐线索同步的时空参照系。为了实现这一目标，使用三维运动捕捉系统记录了桑巴舞和查尔斯顿的重复舞蹈模式。然后从舞者身体的每个关节提取几何图案。该方法使用以身体为中心的参照系，并将运动分解成与音乐节拍的周期相匹配的非正交周期。音乐线索(如节拍和响度)以及基于动作的线索(如速度)可以投射到图案上，从而为动作-知觉耦合提供时空参照系或“基本手势”。从概念上讲，时空参照系控制着动作-知觉耦合中的最小努力点。它们作为记忆模式驻留在心理和/或运动域，准备在舞蹈动作中动态转换。本研究提出了一些与空间认知相关的假设，可作为未来舞蹈/音乐研究的指导原则。
THE GOAL OF THE PRESENT STUDY IS TO GAIN BETTER insight into how dancers establish, through dancing, a spatiotemporal reference frame in synchrony with musical cues. With the aim of achieving this, repetitive dance patterns of samba and Charleston were recorded using a three-dimensional motion capture system. Geometric patterns then were extracted from each joint of the dancer's body. The method uses a body-centered reference frame and decomposes the movement into non-orthogonal periodicities that match periods of the musical meter. Musical cues (such as meter and loudness) as well as action-based cues (such as velocity) can be projected onto the patterns, thus providing spatiotemporal reference frames, or 'basic gestures,' for action-perception couplings. Conceptually speaking, the spatiotemporal reference frames control minimum effort points in action-perception couplings. They reside as memory patterns in the mental and/or motor domains, ready to be dynamically transformed in dance movements. The present study raises a number of hypotheses related to spatial cognition that may serve as guiding principles for future dance/music studies.
