Much research has investigated the representation of implicitly learned motor sequences: Do subjects learn sequences of stimuli, responses, response locations, or some combination? Most of the work on this subject indicates that when sequences are learned implicitly, it is in terms of response locations. The present work investigated the representation of explicitly learned motor sequences. In four experiments, we found consistent evidence that explicitly learned sequences are represented in terms of stimulus locations. This conclusion held true for both self-report measures (subjects said that they learned stimuli) and performance measures, but when stimuli changed, performance degraded. We interpret these data in a multiple-memory-systems framework.
受试者学习的是刺激序列、反应序列、反应位置序列，还是某种组合？关于这个主题的大多数研究表明，当序列是内隐学习时，是根据反应位置来进行的。本研究调查了外显学习的运动序列的表征。在四项实验中，我们发现了一致的证据，表明外显学习的序列是根据刺激位置来表征的。这一结论在自我报告测量（受试者表示他们学习了刺激）和表现测量中均成立，但当刺激发生变化时，表现会下降。我们在多记忆系统框架中解释这些数据。
