Recent research has demonstrated that memory-consolidation processes can be accelerated if newly learned information is consistent with preexisting knowledge. Until now, investigations of this fast integration of new information into memory have focused on the declarative and perceptual systems. We employed a unique manipulation of a motor-sequence-learning paradigm to examine the effect of experimentally acquired memory on the learning of new motor information. Results demonstrate that new information is rapidly integrated into memory when practice occurs in a framework that is compatible with the previously acquired memory. This framework consists of the ordinal representation of the motor sequence. This enhanced integration cannot be explained by differences in the explicit awareness of the sequence and is observed only if the previously acquired motor memory was consolidated overnight. Results are consistent with the schema model of memory consolidation and offer insights into how previous motor experience can accelerate learning and consolidation processes.
最近的研究表明，如果新学习的信息与已有知识一致，记忆巩固过程可以加快。到目前为止，对这种新信息快速融入记忆的研究主要集中在陈述性和感知系统上。我们采用了一种独特的运动序列学习范式的操作，来研究实验获得的记忆对新运动信息学习的影响。结果表明，当练习与以前获得的记忆兼容的框架时，新信息会迅速融入记忆。这个框架由运动序列的有序表示组成。只有在前一天晚上巩固了已获得的运动记忆时，这种增强的整合才不能用对序列的明确意识的差异来解释，并且只有在前一天晚上巩固了已获得的运动记忆时，这种增强的整合才会被观察到。结果与记忆巩固的图式模型一致，并为了解先前的运动经验如何加速学习和巩固过程提供了线索。
