我们使用事件相关电位（ERP）来研究成年人在进行（a）复杂结构序列的顺序学习任务和（B）语言加工任务时大脑活动的时间过程和分布。同样的积极ERP偏转，P600效应，通常与困难或不合语法的句法处理，被发现在顺序学习以及自然语言的结构不一致，并具有类似的地形分布。此外，左前负波（LAN）被观察到的语言，但不是连续的学习。这些结果被解释为一个指示，P600提供了一个指数的违规和成本的整合预期即将到来的材料时，处理复杂的序列结构。我们的结论是，同样的神经机制可以招募的句法处理的语言刺激和结构化序列模式的顺序学习更普遍。
We used event-related potentials (ERPs) to investigate the time course and distribution of brain activity while adults performed (a) a sequential learning task involving complex structured sequences, and (b) a language processing task. The same positive ERP deflection, the P600 effect, typically linked to difficult or ungrammatical syntactic processing, was found for structural incongruencies in both sequential learning as well as natural language, and with similar topographical distributions. Additionally, a left anterior negativity (LAN) was observed for language but not for sequential learning. These results are interpreted as an indication that the P600 provides an index of violations and the cost of integration of expectations for upcoming material when processing complex sequential structure. We conclude that the same neural mechanisms may be recruited for both syntactic processing of linguistic stimuli and sequential learning of structured sequence patterns more generally.
