人们可以准确地预测他人的行动结果。为了做到这一点，最近的研究表明，熟练的运动员优先依赖于感觉运动共振机制，在他们自己的运动系统中模拟他人的动作。然而，很少有人知道哪些类型的信息是模拟预测。在这里，我们使用了一个运动错觉，选择性地影响动觉的感觉，以调查运动员是否使用动觉信息模拟预测动作结果时。9名熟练和9名不太熟练的右撇子篮球运动员在3种条件下观看另一名右撇子球员投篮的遮挡视频时预测篮球投篮的结果：（a）单独观察（控制）。(b)观察+右腕的振动诱导的错觉动觉（效应器振动），和（c）观察+左腕的振动（非效应器振动）。结果表明，在控制条件下，熟练的球员的预测增强被消除在效应器振动条件下，但不是在noneffector条件。此外，当参与者作出正确的预测，他们的主观感觉的手腕弯曲引起的振动变得更大，当参与者观察到更长的镜头在效应器的条件，而不是非效应器的条件。结果表明，熟练的球员使用肢体特定的动觉信息，当它是可用的，作为一种手段来预测其他人的行动结果。
People can accurately predict others' action outcomes. To do so, recent studies have proposed that skilled athletes rely preferentially on sensorimotor resonance mechanisms that simulate in their own motor system-the actions of others. However, little is known about which types of information are simulated for prediction. Here, we used a movement-illusion that selectively affected kinaesthetic sensation to investigate whether athletes use kinaesthetic information for simulation when predicting action outcomes. Nine skilled and 9 less-skilled right-handed basketball players predicted the outcomes of basketball shots when viewing an occluded video of another right-handed player's shots in each of 3 conditions: (a) observation alone (control). (b) observation + vibration-induced illusory kinaesthetic sensation in the right-wrist (effector vibration), and (c) observation + vibration in the left-wrist (noneffector vibration). Results revealed that the enhanced prediction of skilled players in the control condition was eliminated in the effector vibration condition but not in the noneffector condition. Additionally, when participants made correct predictions, their subjective feeling of wrist-flexion induced by vibration became larger when participants observed the longer shot in the effector condition but not the noneffector condition. The results suggest that skilled players use limb-specific kinaesthetic information, when it is available, as a means of predicting the action outcomes of others.
