当任务暴露促进绩效，而不产生相应的变化，在言语知识，学习被称为是内隐的。在实验1中，事件相关电位（ERP）被记录为个人实行的内隐结构化序列学习（ISSL）任务，其中只有一些目标事件需要一个反应。随着实践，ERPs的目标，遵守潜在的语法偏离那些没有在200毫秒左右，语法目标似乎是更积极的200和500毫秒之间，因为类似的积极性的非语法目标被延迟。在实验2中，语法被简化，允许一个内隐学习组和一个显式组，谁教的语法之前，记录之间的直接比较。比较的结果显示了显着的相似性，但暗示至少部分不相同的神经机制，内隐和外显结构序列学习。
When task exposure facilitates performance without producing corresponding changes in verbalizable knowledge, learning is said to be implicit. In Experiment 1, event-related potentials (ERPs) were recorded as individuals practiced an implicit structured sequence learning (ISSL) task wherein only some target events required a response. With practice, the ERPs to targets that obeyed the underlying grammar diverged from those that did not at around 200 ms; grammatical targets appeared to be more positive between 200 and 500 ms because a similar positivity for the ungrammatical targets was delayed. In Experiment 2, the grammar was simplified allowing a direct comparison to be made between an implicit learning group and an explicit group, who were taught the grammar prior to recording. The results of the comparison revealed a remarkable similarity but did implicate at least partially nonidentical neural mechanisms in implicit and explicit structured sequence learning.
