Illusory motion of the unseen stationary forearm can be elicited by vibration of the biceps brachii or triceps brachii muscle. We have studied in 12 individuals how sight of part of the arm alone or in relation to other objects affects such vibration-induced, illusory motion of the forearm. Our findings indicate a complex but systematic influence of vision in attenuating apparent motion of the forearm. They show, too, that the seen and felt positions of the forearm can be dissociated and that physically impossible spatial configurations of the arm can be experienced. These findings have implications for physiological theories of position sense.
通过肱二头肌或肱三头肌的振动，可以诱发静止但看不见的前臂产生虚幻运动。我们对12名受试者进行了研究，观察仅看到手臂的一部分或其与其他物体的关系如何影响这种由振动诱发的前臂虚幻运动。我们的研究结果表明，视觉在减弱前臂的明显运动方面具有复杂但系统的影响。研究结果还表明，前臂的视觉位置和感觉位置可能会出现分离，而且可能会体验到手臂在物理上不可能存在的空间构型。这些发现对位置感的生理学理论具有启示意义。
