本研究探讨了听一首新学的音乐作品对随后的运动记忆的影响。36名非音乐家被训练在钢琴键盘上演奏一段不熟悉的旋律。接下来，他们被随机分配参加为期一周的三次后续听力课程。受试者，在他们的听力会议期间，听相同的初始作品显示出显着的改善，运动记忆和保留的一块，尽管缺乏物理实践。这些改进包括提高了音高准确性、时间准确性和按键的动态强度。类似的改善，虽然程度较低，在受试者中观察到，在他们的听力会议期间，被另一项任务分心。对照组受试者，谁学习的一块听了非音乐的声音，表现出受损的运动保留的一块在1周从最初的收购日。这些结果表明，运动序列可以建立在运动记忆中，而无需直接访问与运动相关的信息。此外，该研究还表明，由音乐刺激引起的改善并不能推广到学习由与最初学习的音乐作品相同的音符组成的新音乐作品，这将影响限制在已经是个人运动曲目的一部分的音乐运动序列上。
This study examined the effect of listening to a newly learned musical piece on subsequent motor retention of the piece. Thirty-six non-musicians were trained to play an unfamiliar melody on a piano keyboard. Next, they were randomly assigned to participate in three follow-up listening sessions over 1 week. Subjects who, during their listening sessions, listened to the same initial piece showed significant improvements in motor memory and retention of the piece despite the absence of physical practice. These improvements included increased pitch accuracy, time accuracy, and dynamic intensity of key pressing. Similar improvements, though to a lesser degree, were observed in subjects who, during their listening sessions, were distracted by another task. Control subjects, who after learning the piece had listened to nonmusical sounds, showed impaired motoric retention of the piece at 1 week from the initial acquisition day. These results imply that motor sequences can be established in motor memory without direct access to motor-related information. In addition, the study revealed that the listening-induced improvements did not generalize to the learning of a new musical piece composed of the same notes as the initial piece learned, limiting the effects to musical motor sequences that are already part of the individual’s motor repertoire.
