双语能力的研究主要集中在单词和句子的处理，而文本层面的关注相对较少。我们研究了在线第二语言（L2）的文本理解与L2水平与ERP记录的关键词跨越句子边界从他们的共指先行词。关键词的整合过程旨在反映不同层次的文本表征：词的形式，词的意义，和情景的水平。在不同的熟练程度上，双语者表现出与词义整合（N400）和心理模型更新（LPC）过程相关的双相N400/晚期阳性成分（LPC）效应。更熟练的双语者，与不太熟练的双语者相比，在N400和LPC的振幅降低时，集成依赖于语义和概念意义。当整合是基于单词重复和推理，两组都表现出减少N400负性，而LPC阳性升高。这些效应反映了记忆机制（过程和资源）如何支持单词意义、读者对文本意义的记忆和文本的指称指定意义之间的紧密耦合。他们进一步证明了二语语义和概念加工在调节二语水平对二语篇整合过程的影响中的重要性。这些结果符合假设，即词义过程是因果成分的理解能力的变化，无论是单语者和双语者。
Studies of bilingual proficiency have largely focused on word and sentence processing, whereas the text level has received relatively little attention. We examined on-line second language (L2) text comprehension in relation to L2 proficiency with ERPs recorded on critical words separated across a sentence boundary from their co-referential antecedents. The integration processes on the critical words were designed to reflect different levels of text representation: word-form, word-meaning, and situational levels. Across proficiency level, bilinguals showed biphasic N400/late positive component (LPC) effects related to word meaning integration (N400) and mental model updating (LPC) processes. More proficient bilinguals, compared with less proficient bilinguals, showed reduced amplitudes in both N400 and LPC when the integration depended on semantic and conceptual meanings. When the integration was based on word repetitions and inferences, both groups showed reduced N400 negativity while elevated LPC positivity. These effects reflect how memory mechanisms (processes and resources) support the tight coupling among word meaning, readers’ memory of the text meaning and the referentially-specified meaning of the text. They further demonstrate the importance of L2 semantic and conceptual processing in modulating the L2 proficiency effect on L2 text integration processes. These results align with the assumption that word meaning processes are causal components in variations of comprehension ability for both monolinguals and bilinguals.
