同步动作被认为是共享技能的体现。人类和其他动物的大多数同步行为都是基于周期性重复。在同步说话的实验任务中发现了复杂动作的非周期性同步，其中天真的受试者以锁定步骤阅读共同文本。没有周期性基础的同步行为的演示对理论理解提出了挑战。通过用任务特定的感觉运动协调的更局部的概念取代认知主义方法的顺序处理模型，建议对周期性和非周期性同步进行统一处理。根据这种观点，熟练的动作是对运动和感觉通量的共同变化施加限制，从而满足定义技能的边界条件。这种非认知主义方法起源于约翰·杜威的著作。它允许在简单的节奏行为和复杂的技能行为中统一处理感觉运动同步，并且它表明技能共享是具有相当重要意义的人类独特特征。
Synchronized action is considered as a manifestation of shared skill. Most synchronized behaviors in humans and other animals are based on periodic repetition. Aperiodic synchronization of complex action is found in the experimental task of synchronous speaking, in which naive subjects read a common text in lock step. The demonstration of synchronized behavior without a periodic basis is presented as a challenge for theoretical understanding. A unified treatment of periodic and aperiodic synchronization is suggested by replacing the sequential processing model of cognitivist approaches with the more local notion of a task-specific sensorimotor coordination. On this view, skilled action is the imposition of constraints on the co-variation of movement and sensory flux such that the boundary conditions that define the skill are met. This non-cognitivist approach originates in the work of John Dewey. It allows a unification of the treatment of sensorimotor synchronization in simple rhythmic behavior and in complex skilled behavior and it suggests that skill sharing is a uniquely human trait of considerable import.
