感觉运动适应是通过从感觉反馈中学习来减少运动错误的过程，通常在大约半个小时的时间内进行研究。在这样的一次会议中，适应通常在错误完全消除之前达到平台期。然而，适应可能会在更长的时间尺度上完成：基于错误的适应的缓慢成分与良好的保持能力有关。在这项研究中，我们通过让参与者在不同的日子进行六次适应会议来测试适应如何随着时间的推移而演变。在这些会话中，参与者执行三维到达任务，同时关于终点误差的视觉反馈绕着圆眼旋转。此外，通过测量肢体间转移和转移到视觉和本体知觉任务，解决了适应的语境特异性。我们表明，从第二届会议开始，适应几乎完全在各届会议之间保留。然而，经过六次学习后，适应仍然达到了平台期，错误才被完全消除。适应是特定的：适应既没有转移到另一只手，也没有转移到视觉上，只是略微转移到本体知觉估计上。我们的结论是，运动适应是健壮的、特定的和不完整的。
Sensorimotor adaptation, the process that reduces movement errors by learning from sensory feedback, is often studied within a session of about half an hour. Within such a single session, adaptation generally reaches plateau before errors are completely removed. However, adaptation may complete on longer timescales: the slow components of error‐based adaptation are associated with good retention. In this study, we tested how adaptation evolves over time by asking participants to perform six adaptation sessions on different days. In these sessions, participants performed a three‐dimensional reaching task while visual feedback about endpoint errors was rotated around the cyclopean eye. In addition, context specificity of the adaptation was addressed by measuring inter‐limb transfer and transfer to visual and proprioceptive perceptual tasks. We show that from the second session on, the adaptation was retained almost completely across sessions. However, after six learning sessions, adaptation still reached plateau before errors were completely removed. The adaptation was specific: the adaptation did neither transfer to the other hand, nor to the visual, and only marginally to the proprioceptive perceptual estimates. We conclude that motor adaptation is robust, specific and incomplete.
