Humans often share roles and aim to achieve a group goal based on sociality, which is the tendency to spontaneously involve oneself with others. Cognitive science, psychology, and neuroscience studies suggest that in such planned coordination, adjusting one's own actions based on other roles is crucial for high task performance. However, the mechanisms of complex and dynamically planned coordination, such as non-verbal group behavior with three or more members, remain to be fully investigated. This study introduced a coordinated drawing task in a triad, quantitatively analyzed non-verbal group behavior based on sharing heterogeneous roles, and investigated an important role. Participant triads engaged in the task repeatedly by operating reels to change thread tensions and moving a pen connected to the three threads to draw an equilateral triangle. Then, the three roles (pulling, relaxing, and adjusting) had to be shared. The pulling and relaxing roles served to move the pen as if an operator pulled it closer to the hand and to support the pen's movement, respectively. However, these roles alone could not draw a side considering the task specification. The adjusting role needed to change the tension flexibly and maintain an overall balance. In the experiment, we measured the pen positions and tensions, and established statistical models to fit the analyzed data. The results estimated that the action in the adjusting role was related to the improved performance of faster drawing on a side. This role may moderately intervene in the actions by the other roles and fine-tune without disturbing the pen's smooth movement while avoiding great pen deviation. Our findings may suggest the crucial role as a facilitator that handles resiliently in non-verbal coordinated behavior of a triad, and contribute to our understanding of social interactions.
人类常常共享角色，并基于社会性致力于实现群体目标，社会性即自发与他人交往的倾向。认知科学、心理学和神经科学研究表明，在这种有计划的协调中，根据其他角色调整自身行为对于高任务绩效至关重要。然而，复杂且动态规划的协调机制，如三个或更多成员的非语言群体行为，仍有待充分研究。本研究引入了三人一组的协同绘图任务，基于共享不同角色对非语言群体行为进行定量分析，并探究了一个重要角色。参与的三人小组通过操作卷轴来改变线的张力，并移动连接到三根线的笔来绘制一个等边三角形，从而反复进行该任务。然后，必须共享三个角色（拉动、放松和调整）。拉动和放松角色分别用于移动笔，就好像操作员将笔拉近手部，并支撑笔的移动。然而，仅靠这些角色无法根据任务要求绘制出一条边。调整角色需要灵活改变张力并保持整体平衡。在实验中，我们测量了笔的位置和张力，并建立统计模型以拟合分析数据。结果估计，调整角色中的动作与更快绘制一条边的性能提升有关。这个角色可能适度干预其他角色的动作，并在不干扰笔的平稳移动的同时进行微调，同时避免笔的大幅偏离。我们的研究结果可能表明，在三人小组的非语言协调行为中，该角色作为一个能灵活应对的促进者起着关键作用，并有助于我们对社会互动的理解。
