我们提出了三个事件相关电位研究，调查的贡献，给予性和位置引起的话题性（一个句子是关于什么）的信息处理。研究比较了两种不同位置的指称表达（给定和推断名词短语（NP））。数据显示，位置特定的影响，反映了主题性和givenness的相互作用：推断的NP注册一个更明显的晚阳性比给定的NP在典型的中间位置，但不是中间最初（实验1）。此外，存在跨位置的给定性的稳定效应，其由针对给定NP推断的N400反映。从语篇动态的角度来看，N400被认为反映了语境诱导的连接过程。后期积极性与语篇结构的维持和更新有关，体现了特定位置的信息存储指令。随后的研究加强了这一信息包装的帐户表明，后期积极性模式是不受句法功能重新分析（实验2）或错位的要求（实验3）。
We present three event-related potential studies that investigated the contribution of givenness and position-induced topicality (what a sentence is about) to information processing. The studies compared two types of referential expressions (given and inferred noun phrases (NPs)) in distinct sentential positions. The data revealed position-specific effects, reflected by an interaction of topicality and givenness: inferred NPs registered a more pronounced Late Positivity than given NPs in the canonical sentence-medial position, but not sentence-initially (Experiment 1). Additionally, there was a stable effect of givenness across positions, reflected by an N400 for inferred over given NPs. From a discourse dynamic perspective, the N400 is considered to reflect context-induced linking processes. The Late Positivity is associated with maintaining and updating discourse structure and manifests position-specific instructions for information storage. Subsequent studies strengthened this information packaging account by showing that the Late Positivity pattern is unaffected by syntactic function reanalysis (Experiment 2) or dislocation demands (Experiment 3).
