Recently, researchers have measured hand movements en route to choices on a screen to understand the dynamics of a broad range of psychological processes. We review this growing body of research and explain how manual action exposes the real-time unfolding of underlying cognitive processing. We describe how simple hand motions may be used to continuously index participants' tentative commitments to different choice alternatives during the evolution of a behavioral response. As such, hand-tracking can provide unusually high-fidelity, real-time motor traces of the mind. These motor traces cast novel theoretical and empirical light onto a wide range of phenomena and serve as a potential bridge between far-reaching areas of psychological science - from language, to high-level cognition and learning, to social cognitive processes.
最近，研究人员在人们做出屏幕选择的过程中测量了手部动作，以了解广泛心理过程的动态变化。我们回顾了这一不断发展的研究领域，并解释了手部动作如何揭示潜在认知过程的实时展开。我们描述了简单的手部动作如何在行为反应的演变过程中，被用来持续指示参与者对不同选择的初步倾向。因此，手部追踪能够提供关于思维的异常高保真的实时运动轨迹。这些运动轨迹为广泛的现象提供了全新的理论和实证视角，并成为心理学科学诸多领域——从语言、高级认知与学习到社会认知过程——之间的潜在桥梁。
