How do physical interactions with others change our own motor behavior? Utilizing a novel motor learning paradigm in which the hands of two - individuals are physically connected without their conscious awareness, we investigated how the interaction forces from a partner adapt the motor behavior in physically interacting humans. We observed the motor adaptations during physical interactions to be mutually beneficial such that both the worse and better of the interacting partners improve motor performance during and after interactive practice. We show that these benefits cannot be explained by multi-sensory integration by an individual, but require physical interaction with a reactive partner. Furthermore, the benefits are determined by both the interacting partner's performance and similarity of the partner's behavior to one's own. Our results demonstrate the fundamental neural processes underlying human physical interactions and suggest advantages of interactive paradigms for sport-training and physical rehabilitation.
与他人的身体互动如何改变我们自身的运动行为？利用一种新颖的运动学习范式，即两个人的手在无意识的情况下进行身体连接，我们研究了来自伙伴的相互作用力如何在身体互动的人类中调整运动行为。我们观察到身体互动过程中的运动适应性是互利的，即互动伙伴中表现较差和较好的人在互动练习期间及之后都会提高运动表现。我们表明，这些益处无法用个体的多感官整合来解释，而是需要与有反应的伙伴进行身体互动。此外，这些益处由互动伙伴的表现以及伙伴行为与自身行为的相似性共同决定。我们的研究结果揭示了人类身体互动背后的基本神经过程，并表明互动范式在运动训练和身体康复方面的优势。
