We investigated whether the interpersonal postural coordination that occurs during a joint supra-postural, manual precision task is driven by the constraints of the task, or, instead results from visual entrainment to the movements of a co-actor. Participants were instructed to coordinate their finger movements under conditions where participants could see others' whole-body movements or could only see the results of the other's actions. Participants' finger and torso movements were recorded. Coordination was quantified using cross-recurrence quantification analysis measures. Interpersonal coordination was enhanced by, although it did not depend entirely upon, visual information about the co-actor's body movements.
我们研究了在联合超姿势手动精准任务中出现的人际姿势协调是由任务约束驱动的，还是相反，是由于对共同行动者动作的视觉同步所致。参与者被要求在能够看到他人全身动作或只能看到他人动作结果的条件下协调手指动作。记录了参与者的手指和躯干动作。使用交叉递归量化分析方法对协调性进行量化。关于共同行动者身体动作的视觉信息增强了人际协调性，尽管它并不完全依赖于此。
