Using ERPs, we tested whether L2 speakers can integrate multiple sources of information (e.g., semantic, pragmatic information) during discourse comprehension. We presented native speakers and L2 speakers with three-sentence scenarios in which the final sentence was highly causally related, intermediately related, or causally unrelated to its context; its interpretation therefore required simple or complex inferences. Native speakers revealed a gradual N400-like effect, larger in the causally unrelated condition than in the highly related condition, and falling in-between in the intermediately related condition, replicating previous results. In the crucial intermediately related condition, L2 speakers behaved like native speakers, however, showing extra processing in a later time-window. Overall, the results show that, when reading, L2 speakers are able to process information from the local context and prior information (e.g., world knowledge) to build global coherence, suggesting that they process different sources of information to make inferences online during discourse comprehension, like native speakers.
我们使用事件相关电位（ERPs）来测试二语使用者在语篇理解过程中是否能够整合多种信息来源（如语义、语用信息）。我们向母语使用者和二语使用者呈现了由三个句子组成的场景，其中最后一个句子与上下文的因果关系分别为高度相关、中度相关或无因果关系；因此，对其进行解读需要简单或复杂的推理。母语使用者表现出一种类似N400的逐渐变化的效应，在因果关系不相关的条件下比在高度相关的条件下更大，而在中度相关的条件下则介于两者之间，这与之前的研究结果一致。在关键的中度相关条件下，二语使用者的表现与母语使用者相似，然而，他们在较晚的时间窗口中表现出额外的加工过程。总体而言，研究结果表明，在阅读时，二语使用者能够处理来自局部语境和先前信息（如世界知识）的信息，以构建整体连贯性，这表明他们在语篇理解过程中会像母语使用者一样，处理不同的信息来源以便在线进行推理。
