Consolidation is a time-dependent process responsible for the storage of information in long-term memory. As such, it plays a crucial role in motor learning. In two experiments, we sought to determine whether one's performance influences the outcome of the consolidation process. We used a visuomotor adaptation task in which the cursor moved by the participants was rotated 30 degrees clockwise. Thus, participants had to learn a new internal model to compensate for the rotation of the visual feedback. The results indicated that when participants showed good adaptation in the first session, consolidation resulted in a persistent after-effect in a no-rotation transfer test; they had difficulty returning to their normal no-rotation internal model. However, when participants showed poor adaptation in the first session, consolidation led to significant off-line learning (between sessions improvement) but labile after-effects. These observations suggest that distinct consolidation outcomes (off-line learning and persistent after-effect) may occur depending on the learner's initial performance.
巩固是一个依赖时间的过程，负责将信息存储在长期记忆中。因此，它在运动学习中起着至关重要的作用。在两项实验中，我们试图确定一个人的表现是否会影响巩固过程的结果。我们使用了一个视动适应任务，其中参与者的光标顺时针旋转 30 度。因此，参与者必须学习一个新的内部模型来补偿视觉反馈的旋转。结果表明，当参与者在第一阶段表现出良好的适应能力时，巩固会导致在无旋转转移测试中产生持久的后效；他们很难回到正常的无旋转内部模型。然而，当参与者在第一阶段表现出较差的适应能力时，巩固会导致显著的离线学习（两次测试之间的提高）和不稳定的后效。这些观察结果表明，不同的巩固结果（离线学习和持久后效）可能取决于学习者的初始表现。
