Two experiments were designed to determine whether interlimb transfer of prism adaptation follows a pattern predicted by the functional closeness of limb control centres. Subjects were adapted to a lateral displacing prism with their right arm in conditions known to facilitate interlimb transfer. Negative aftereffect measures of target-pointing shift were taken for all limbs. If transfer to the unadapted limbs is primarily the result of some sort of visual change, scores for those limbs should not differ. However, if the functional cerebral closeness of limb control centres is a factor, the greatest shift should be evidenced in the homologous contralateral limb (left arm), followed by the ipsilateral limb (right leg), with the least shift to the diagonally opposite limb (left leg). No differences in shift among the three unadapted limbs was found in the two experiments.
设计了两项实验，以确定棱镜适应的肢体间转移是否遵循肢体控制中心功能接近性所预测的模式。在已知有利于肢体间转移的条件下，让受试者用右臂适应横向移位棱镜。对所有肢体进行目标指向偏移的负后效测量。如果向未适应肢体的转移主要是某种视觉变化的结果，那么这些肢体的得分应该没有差异。然而，如果肢体控制中心的功能性大脑接近性是一个因素，那么最大的偏移应该出现在同源对侧肢体（左臂），其次是同侧肢体（右腿），向对角相对肢体（左腿）的偏移最小。在这两项实验中，未发现三个未适应肢体之间的偏移有差异。
