Abstract

Each individual's movements are sculpted by constant interactions between sensorimotor and sociocultural factors. A theoretical framework grounded in motor control mechanisms articulating how sociocultural and biological signals converge to shape movement is currently missing. Here, we propose a framework for the emerging field of ethnokinesiology aiming to provide a conceptual space and vocabulary to help bring together researchers at this intersection. We offer a first-level schema for generating and testing hypotheses about cultural differences in movement to bridge gaps between the rich observations of cross-cultural movement variations and neurophysiological and biomechanical accounts of movement. We explicitly dissociate two interacting feedback loops that determine culturally relevant movement: one governing sensorimotor tasks regulated by neural signals internal to the body, the other governing ecological tasks generated through actions in the environment producing ecological consequences. A key idea is the emergence of individual-specific and culturally influenced motor concepts in the nervous system, low-dimensional functional mappings between sensorimotor and ecological task spaces. Motor accents arise from perceived differences in motor concept topologies across cultural contexts. We apply the framework to three examples: speech, gait and grasp. Finally, we discuss how ethnokinesiological studies may inform personalized motor skill training and rehabilitation, and challenges moving forward.This article is part of the theme issue 'Minds in movement: embodied cognition in the age of artificial intelligence'.

民族运动学:从神经力学角度理解运动中的文化差异。
每个人的动作都是由感官运动和社会文化因素之间不断的相互作用而形成的。目前还缺少一个以运动控制机制为基础的理论框架,来阐明社会文化和生物信号如何共同塑造运动。在此,我们为新兴的民族运动学领域提出了一个框架,旨在提供一个概念空间和词汇,帮助将这一交叉领域的研究人员聚集在一起。我们提供了一个用于生成和测试运动文化差异假设的第一层架构,以弥合跨文化运动差异的丰富观察结果与运动的神经生理学和生物力学描述之间的差距。我们明确地将决定文化相关运动的两个相互作用的反馈回路分离开来:一个是由身体内部神经信号调节的感官运动任务,另一个是通过在环境中产生生态后果的行动而产生的生态任务。其中的一个关键观点是神经系统中出现了个体特有的、受文化影响的运动概念,即感觉运动和生态任务空间之间的低维功能映射。运动口音产生于不同文化背景下运动概念拓扑结构的感知差异。我们将该框架应用于三个例子:语言、步态和抓握。最后,我们讨论了人种运动学研究如何为个性化运动技能训练和康复提供信息,以及未来面临的挑战。本文是 "运动中的思维:人工智能时代的具身认知 "主题期刊的一部分。

期刊介绍: The journal publishes topics across the life sciences. As long as the core subject lies within the biological sciences, some issues may also include content crossing into other areas such as the physical sciences, social sciences, biophysics, policy, economics etc. Issues generally sit within four broad areas (although many issues sit across these areas): Organismal, environmental and evolutionary biology Neuroscience and cognition Cellular, molecular and developmental biology Health and disease.
