When two individuals interact in a collaborative task, such as carrying a sofa or a table, usually spatiotemporal coordination of individual motor behavior will emerge. In many cases, interpersonal coordination can arise independently of verbal communication, based on the observation of the partners' movements and/or the object's movements. In this study, we investigate how social coupling between two individuals can emerge in a collaborative task under different modes of perceptual information. A visual reference condition was compared with three different conditions with new types of additional auditory feedback provided in real time: effect-based auditory feedback, performance-based auditory feedback, and combined effect/performance-based auditory feedback. We have developed a new paradigm in which the actions of both participants continuously result in a seamlessly merged effect on an object simulated by a tablet computer application. Here, participants should temporally synchronize their movements with a 90° phase difference and precisely adjust the finger dynamics in order to keep the object (a ball) accurately rotating on a given circular trajectory on the tablet. Results demonstrate that interpersonal coordination in a joint task can be altered by different kinds of additional auditory information in various ways.
当两个人在一项协作任务中互动时，比如搬运沙发或桌子，通常会出现个体运动行为的时空协调。在许多情况下，人际协调可以独立于言语交流而产生，这是基于对伙伴动作和/或物体动作的观察。在本研究中，我们探究了在不同感知信息模式下，两个人之间的社会耦合如何在协作任务中出现。将视觉参照条件与三种不同条件进行比较，这三种条件会实时提供新型的额外听觉反馈：基于效果的听觉反馈、基于表现的听觉反馈以及基于效果/表现的组合听觉反馈。我们开发了一种新范式，其中两名参与者的动作会持续对平板电脑应用程序模拟的物体产生无缝融合的效果。在这里，参与者应在时间上使他们的动作保持90°的相位差同步，并精确调整手指动态，以便让物体（一个球）在平板电脑上给定的圆形轨迹上准确旋转。结果表明，联合任务中的人际协调会因不同种类的额外听觉信息而以各种方式发生改变。
