What enables individuals to act together? Recent discoveries suggest that a variety of mechanisms are involved. But something fundamental is yet to be investigated. In joint action, agents represent a collective goal, or so it is often assumed. But how, if at all, are collective goals represented in joint action and how do such representations impact performance? To investigate this question we adapted a bimanual paradigm, the circle-line drawing paradigm, to contrast two agents acting in parallel with two agents performing a joint action. Participants were required to draw lines or circles while observing circles or lines being drawn. The findings indicate that interpersonal motor coupling may occur in joint but not parallel action. This suggests that participants in joint actions can represent collective goals motorically.
是什么使个体能够共同行动？最近的发现表明，其中涉及多种机制。但一些基本问题仍有待研究。在联合行动中，行动者代表着一个共同目标，至少人们常常这样认为。但在联合行动中，共同目标究竟是如何被表征的，以及这些表征如何影响行动表现？为了研究这个问题，我们采用了一种双手范式，即圆圈-线条绘制范式，来对比两个并行行动的行动者和两个进行联合行动的行动者。参与者在观察圆圈或线条被绘制的同时，被要求绘制线条或圆圈。研究结果表明，人际运动耦合可能发生在联合行动而非并行行动中。这表明参与联合行动的参与者能够通过运动来表征共同目标。
