情境干扰是指与随机练习计划相比，受阻的练习计划会导致新运动技能的习得速度更快，但保留效果较差。虽然在广泛的任务中观察到了情境干扰，但目前尚不清楚这种效应是否会推广到过度学习的运动技能的隐式和自动重新校准。为了解决这个问题，我们在视觉运动旋转任务中比较了阻塞练习计划和随机练习计划，该任务隔离了隐式适应。在实验1中，我们发现了隐式适应中上下文干扰的强大特征：与在受阻训练计划下测试的参与者相比，在随机训练计划下测试的参与者在训练阶段表现出学习率降低，但在随后的无反馈评估阶段保持更好。在实验 2 中，我们再次观察到随机练习后记忆力的优势，并表明该结果不是由于训练和评估阶段之间的背景变化所致（例如，训练计划被阻止，然后是随机评估计划）。综上所述，这些结果表明，情境干扰不仅限于获得新的运动技能，还适用于对已建立的运动技能的隐性适应。
Contextual interference refers to the phenomenon whereby a blocked practice schedule results in faster acquisition but poorer retention of new motor skills compared to a random practice schedule. While contextual interference has been observed under a broad range of tasks, it remains unclear if this effect generalizes to the implicit and automatic recalibration of an overlearned motor skill. To address this question, we compared blocked and random practice schedules in a visuomotor rotation task that isolates implicit adaptation. In experiment 1, we found robust signatures of contextual interference in implicit adaptation: compared to participants tested under a blocked training schedule, participants tested under a random training schedule exhibited a reduced rate of learning during the training phase but better retention during a subsequent no-feedback assessment phase. In experiment 2, we again observed an advantage in retention following random practice and showed that this result was not due to a change in context between the training and assessment phases (e.g. a blocked training schedule followed by a random assessment schedule). Taken together, these results indicate that contextual interference is not limited to the acquisition of new motor skills but also applies to the implicit adaptation of established motor skills.
