Emotion and motion, though seldom studied in tandem, are complementary aspects of social experience. This study investigates variations in emotional responses during movement coordination between a human and a Virtual Partner (VP), an agent whose virtual finger movements are driven by the Haken-Kelso-Bunz (HKB) equations of Coordination Dynamics. Twenty-one subjects were instructed to coordinate finger movements with the VP in either inphase or antiphase patterns. By adjusting model parameters, we manipulated the 'intention' of VP as cooperative or competitive with the human's instructed goal. Skin potential responses (SPR) were recorded to quantify the intensity of emotional response. At the end of each trial, subjects rated the VP's intention and whether they thought their partner was another human being or a machine. We found greater emotional responses when subjects reported that their partner was human and when coordination was stable. That emotional responses are strongly influenced by dynamic features of the VP's behavior, has implications for mental health, brain disorders and the design of socially cooperative machines.
情感与动作，尽管很少被同时研究，但却是社会体验中相辅相成的两个方面。本研究调查了人类与虚拟伙伴（VP）进行动作协调时情绪反应的变化，该虚拟伙伴的虚拟手指动作由协调动力学的哈肯-凯尔索-布恩茨（HKB）方程驱动。21名受试者被要求以同相或反相模式与虚拟伙伴协调手指动作。通过调整模型参数，我们将虚拟伙伴的“意图”操纵为与人类指示目标合作或竞争。记录皮肤电位反应（SPR）以量化情绪反应的强度。在每次试验结束时，受试者对虚拟伙伴的意图以及他们是否认为自己的伙伴是另一个人还是机器进行评分。我们发现，当受试者报告他们的伙伴是人类以及协调稳定时，情绪反应更强烈。情绪反应受到虚拟伙伴行为动态特征的强烈影响，这对心理健康、脑部疾病以及社会合作机器的设计具有启示意义。
