虽然运动学习可能涉及多个过程，但在基于错误的运动学习范式中观察到的现象倾向于仅根据单个过程-适应来概念化，这是通过更新内部模型来发生的。在这里，我们认为，基本现象，如运动方向的偏见，储蓄（更快的再学习）和干扰不涉及适应，而是归因于两个额外的学习过程，可以被描述为无模型：使用依赖的可塑性和操作性强化。虽然通常“隐藏”背后的适应，我们证明，与修改后的视觉旋转范例，这些不同的基于模型和无模型的过程联合收割机学习基于错误的运动任务：（1）适应的内部模型渠道走向成功的错误减少在视觉空间的运动。(2)新调整的运动的重复引起朝向重复的运动的方向偏差。(3)通过将适应的运动与成功的错误减少相关联来进行操作性强化是节省的原因。
Although motor learning is likely to involve multiple processes, phenomena observed in error-based motor learning paradigms tend to be conceptualized in terms of only a single process – adaptation, which occurs through updating an internal model. Here we argue that fundamental phenomena like movement direction biases, savings (faster relearning) and interference do not relate to adaptation but instead are attributable to two additional learning processes that can be characterized as model-free: use-dependent plasticity and operant reinforcement. Although usually “hidden” behind adaptation, we demonstrate, with modified visuomotor rotation paradigms, that these distinct model-based and model-free processes combine to learn an error-based motor task: (1) Adaptation of an internal model channels movements toward successful error reduction in visual space. (2) Repetition of the newly adapted movement induces directional biases towards the repeated movement. (3) Operant reinforcement through association of the adapted movement with successful error reduction is responsible for savings.
