学习复杂的运动行为，如骑自行车或挥动高尔夫球杆，是基于获得运动的机械要求的神经表征（例如，协调肌肉力量以控制球杆）。在这里，我们提供的证据表明，机制匹配的观察和行动促进运动学习。观察到一段描述另一个人在一个新的机械环境（由机器人手臂施加）中学习伸手的视频的受试者，后来在相同的环境中进行测试时，比观察到类似动作但没有学习的受试者表现得更好;此外，观察到学习不同环境的受试者表现得更差。我们表明，这种效果是不是基于有意识的策略，而是取决于运动规划和控制的神经系统的内隐参与。
Learning complex motor behaviors like riding a bicycle or swinging a golf club is based on acquiring neural representations of the mechanical requirements of movement (e.g., coordinating muscle forces to control the club). Here we provide evidence that mechanisms matching observation and action facilitate motor learning. Subjects who observed a video depicting another person learning to reach in a novel mechanical environment (imposed by a robot arm) performed better when later tested in the same environment than subjects who observed similar movements but no learning; moreover, subjects who observed learning of a different environment performed worse. We show that this effect is not based on conscious strategies but instead depends on the implicit engagement of neural systems for movement planning and control.
