本文报道的研究使用干扰范式来确定两种内隐运动技能、运动序列和视觉运动映射的组合是否发生长期巩固过程（即持续数小时至数天的过程）。受试者学习了一项技能，并在48小时后对该技能进行测试。在组队和测试之间，一些受试者接受了第二项技能的训练。不同的实验对象使用这两种技能的时间间隔是不同的。在运动序列的组合和视觉-运动映射的组合中，我们发现远程记忆容易受到干扰，但时间的流逝并不能提供免受干扰的保护。这些结果与这些运动技能的长期巩固不一致。这些任务和那些表现出长期巩固的任务之间的一个可能的区别是，当前的任务不是动态运动技能。
The studies reported here used an interference paradigm to determine whether a long-term consolidation process (i.e., one lasting from several hours to days) occurs in the teaming of two implicit motor skills, teaming of a movement sequence and teaming of a visuo-motor mapping. Subjects learned one skill and were tested on that skill 48 h later. Between the teaming session and test session, some subjects trained on a second skill. The amount of time between the teaming of the two skills varied for different subjects. In both the teaming of a movement sequence and the teaming of a visuo-motor mapping, we found that remote memories were susceptible to interference, but the passage of time did not afford protection from interference. These results are inconsistent with the long-term consolidation of these motor skills. A possible difference between these tasks and those that do show long-term consolidation is that the present tasks are not dynamic motor skills.
