The phenomenal hypothesis that prism aftereffects depend upon sight of the limb was tested in a ball-throwing task during prism exposure; the participant's (N = 28) limb was either visible or not visible, but feedback from the moving ball was available during the exposure. Aftereffects were clearly demonstrated in both the visible- and nonvisible-limb conditions, and total aftereffect was larger for participants in the nonvisible-limb condition. Proprioceptive aftereffects were greater than visual aftereffects in the visible-limb group; however, the reverse was true for the nonvisible-limb group. Those results support a processing hypothesis in which sensory feedback, not phenomenal experience, is necessary.
在棱镜暴露期间的投球任务中，对棱镜后效取决于肢体视觉的这一显著假设进行了测试；参与者（N = 28）的肢体要么可见，要么不可见，但在暴露期间可获得来自移动球的反馈。在肢体可见和不可见条件下均清楚地证明了后效，并且在肢体不可见条件下参与者的总后效更大。在肢体可见组中，本体感受后效大于视觉后效；然而，在肢体不可见组中情况则相反。这些结果支持了一种加工假设，即感觉反馈而非现象体验是必要的。
