The goal of this study was to analyze the interpersonal coordination of patients suffering from schizophrenia (SZ) using a humanoid robot NAO. NAO was controlled by a neurally-inspired model that enables motions synchronization between robot and human. Using a robot has the advantage in that it can be modified and controlled without being influenced by the human with whom they are interacting. More specifically, we were interested in non-intentional interpersonal coordination which has been found in previous studies to be preserved for SZ. We performed an experiment in which we asked patients and control participants to jointly perform fitness movements with the robot which was programmed to either synchronize with the human (a bidirectional condition) or move at a fixed frequency with them (a unidirectional condition). We showed that non-intentional interpersonal coordination was preserved for SZ during Human/Robot interaction (as for human/human interaction). Also, the best synchronization, stability and the best performance in term of speed were obtained with the bidirectional condition. Our results showed that, in this specific context of an interaction at preferential frequency of subject, there were only a few differences between SZ and controls in terms of interpersonal synchronization skills. Nevertheless, we observed more variability for SZ which could partly be explained by the weaker intrapersonal coordination that they exhibited.

这项研究的目的是使用类人机器人NAO分析精神分裂症（SZ）患者的人际协调。NAO由神经启发模型控制，该模型使机器人与人类之间的运动同步。使用机器人的优势在于，可以对其进行修改和控制，而不受与之交互的人类的影响。更具体地说，我们对非故意的人际协调感兴趣，在以前的研究中发现这种非故意的人际协调可以保留给深圳。我们进行了一项实验，要求患者和控制参与者与机器人共同执行健身运动，该机器人被编程为与人类同步（双向条件）或以固定频率与人类移动（单向条件）。我们表明，在人机交互过程中（对于人机交互），SZ保留了非故意的人际协调。同样，在双向条件下，可以获得最佳的同步性，稳定性和最佳的速度性能。我们的研究结果表明，在特定频率的主题优先互动中，SZ和控件之间在人际同步技能方面仅存在一些差异。但是，我们观察到了SZ的更多可变性，这在一定程度上可以通过他们表现出的较弱的人际协调来解释。在双向条件下获得了稳定性和最佳的速度性能。我们的研究结果表明，在特定频率的主题优先互动中，SZ和控件之间在人际同步技能方面仅存在一些差异。但是，我们观察到了SZ的更多可变性，这在一定程度上可以通过他们表现出的较弱的人际协调来解释。在双向条件下获得了稳定性和最佳的速度性能。我们的研究结果表明，在特定频率的主题优先互动中，SZ和控件之间在人际同步技能方面仅存在一些差异。但是，我们观察到了SZ的更多可变性，这在一定程度上可以通过他们表现出的较弱的人际协调来解释。
