Much work on communication and joint action conceptualizes interaction as a dynamical system. Under this view, dynamic properties of interaction should be shaped by the context in which the interaction is taking place. Here we explore or -the degree to which individuals move in similar ways over time-as one such context-sensitive property. Studies of coordination have typically investigated how these dynamics are influenced by either (i.e., slow-changing factors) or (i.e., fast-changing factors like movement). Focusing on nonverbal communication behaviors during naturalistic conversation, we analyzed how interacting participants' head movement dynamics were shaped simultaneously by high-level constraints (i.e., conversation type; friendly conversations vs. arguments) and low-level constraints (i.e., perceptual stimuli; non-informative visual stimuli vs. informative visual stimuli). We found that high- and low-level constraints interacted non-additively to affect interpersonal movement dynamics, highlighting the context sensitivity of interaction and supporting the view of joint action as a complex adaptive system.
许多关于交流与联合行动的研究将互动概念化为一个动态系统。在这种观点下，互动的动态特性应由互动发生的背景塑造。在此，我们探讨个体随时间推移以相似方式移动的程度——作为一种此类情境敏感特性。协调性研究通常考察这些动态如何受到结构（即缓慢变化的因素）或耦合（即像动作这样快速变化的因素）的影响。聚焦于自然对话中的非言语交流行为，我们分析了互动参与者头部运动动态如何同时受到高级约束（即对话类型；友好对话与争论）和低级约束（即感知刺激；非信息性视觉刺激与信息性视觉刺激）的塑造。我们发现高级和低级约束以非相加的方式相互作用，从而影响人际运动动态，突出了互动的情境敏感性，并支持将联合行动视为一个复杂自适应系统的观点。
