面对不断变化的生理状态、生物力学约束和环境背景，多种学习过程有助于成功地采取目标导向的行动。在这些过程中，隐式感觉运动适应至关重要，它可确保运动保持良好校准和准确。关于伸手动作的大量工作都强调了适应如何集中在旨在最大限度地减少视觉错误的迭代过程中。本体感觉的作用在很大程度上被忽视了，人们认为本体感觉发挥被动作用，其中本体感觉受到视觉误差的影响，但并不直接有助于适应。在这里，我们提出了这种以视觉为中心的框架的替代方案，概述了一个模型，其中隐式适应可以最大限度地减少本体感觉误差，即感知的手部位置与其预期目标之间的距离。这种本体感受重新调整模型（PReMo）与之前通过视觉错误学习来解释的许多现象是一致的，并且对许多无法解释的现象提供了简洁的解释。认识到 PReMo 的证据依赖于相关研究，我们强调了未来实验中要测试的核心预测，并指出了基于本体感受的内隐适应视角的潜在挑战。
Multiple learning processes contribute to successful goal-directed actions in the face of changing physiological states, biomechanical constraints, and environmental contexts. Amongst these processes, implicit sensorimotor adaptation is of primary importance, ensuring that movements remain well-calibrated and accurate. A large body of work on reaching movements has emphasized how adaptation centers on an iterative process designed to minimize visual errors. The role of proprioception has been largely neglected, thought to play a passive role in which proprioception is affected by the visual error but does not directly contribute to adaptation. Here, we present an alternative to this visuo-centric framework, outlining a model in which implicit adaptation acts to minimize a proprioceptive error, the distance between the perceived hand position and its intended goal. This proprioceptive re-alignment model (PReMo) is consistent with many phenomena that have previously been interpreted in terms of learning from visual errors, and offers a parsimonious account of numerous unexplained phenomena. Cognizant that the evidence for PReMo rests on correlational studies, we highlight core predictions to be tested in future experiments, as well as note potential challenges for a proprioceptive-based perspective on implicit adaptation.
