本文描述了40名受试者佩戴眼动仪，观看和模仿手指，手和手臂运动的视频进行的实验。对于所有类型的刺激，受试者都倾向于盯着手，不管他们是模仿还是只是观看。这些结果有助于了解视觉感知和运动控制之间的联系，表明：（1）人们主要通过跟踪手或终点来分析人的手臂运动，即使运动是用整个手臂执行的，以及（2）当模仿时，人们使用内在的和学习的运动模型，可能以运动原语的形式，以从终点轨迹重新创建整个手臂姿势和运动的细节。(C)1998 Elsevier Science B.V.保留所有权利。
This paper describes experiments performed with 40 subjects wearing an eye-tracker and watching and imitating videos of finger, hand, and arm movements. For all types of stimuli, the subjects tended to fixate on the hand, regardless of whether they were imitating or just watching. The results lend insight into the connection between visual perception and motor control, suggesting that: (1) people analyze human arm movements largely by tracking the hand or the end-point, even if the movement is performed with the entire arm, and (2) when imitating, people use internal innate and learned models of movement, possibly in the form of motor primitives, to recreate the details of whole-arm posture and movement from end-point trajectories.
