本文比较了光和触摸之间的视运动与两个光或两个触摸之间的视运动的属性。视觉和触觉刺激器连接到两个食指的尖端，这两个食指以不同的距离分开。受试者对一系列刺激起始时间（SOA）的每个刺激组合之间的表观运动质量进行评级。受试者报告感知明显的运动之间的所有三个刺激组合。对于光-光视觉表观运动，首选SOA和方向阈值SOA随着刺激之间距离的增加而增加（与Korte的第三定律一致）。触摸触摸明显的运动也服从科特的第三定律，但在一个较小的范围内的距离，表明本体感觉信息的位置的手指集成到触觉运动系统。阈值和首选SOA的视触觉表观运动并不随距离而变化，这表明一个不同的机制，多模态表观运动。
This article compares the properties of apparent motion between a light and a touch with apparent motion between either two lights or two touches. Visual and tactile stimulators were attached to the tips of the two index fingers that were held apart at different distances. Subjects rated the quality of apparent motion between each stimulus combination for a range of stimulus onset asynchronies (SOAs). Subjects reported perceiving apparent motion between all three stimulus combinations. For light-light visual apparent motion, the preferred SOA and the direction threshold SOAs increased as the distance between the stimuli increased (consistent with Korte's third law of apparent motion). Touch-touch apparent motion also obeyed Korte's third law, but over a smaller range of distances, showing that proprioceptive information concerning the position of the fingers is integrated into the tactile motion system. The threshold and preferred SOAs for visuotactile apparent motion did not vary with distance, suggesting a different mechanism for multimodal apparent motion.
