本研究旨在探讨词汇联想和语篇一致性如何影响口语语篇中词汇加工的时间进程。在ERP规范化研究中，我们提出了启动目标对在缺乏句子上下文，以获得一个基线测量词汇启动。我们观察到一个典型的N400效应时，参与者听到关键的关联和无关联的目标词的词对。在随后的实验中，我们提出了相同的词对在口语话语背景。目标词总是与当地的句子上下文一致，但与全球话语一致或不一致（例如，“幸运的是，本已经拿起了一些盐和胡椒/罗勒”，前面的上下文本正在准备marinara酱料（一致）或处理结冰的人行道（不一致）。整体语篇一致性的ERP效应先于局部词汇联想的效应，这表明即使在局部一致的背景下，整体语篇表征也会对词汇加工产生早期影响。此外，词汇联想效应在一致条件下比不一致条件下更早出现。这些结果与阅读研究中获得的结果不同，表明这种影响可能是口语单词识别所独有的。
The goal of this study was to examine how lexical association and discourse congruence affect the time course of processing incoming words in spoken discourse. In an ERP norming study, we presented prime-target pairs in the absence of a sentence context to obtain a baseline measure of lexical priming. We observed a typical N400 effect when participants heard critical associated and unassociated target words in word pairs. In a subsequent experiment, we presented the same word pairs in spoken discourse contexts. Target words were always consistent with the local sentence context, but were congruent or not with the global discourse (e.g., “Luckily Ben had picked up some salt and pepper/basil”, preceded by a context in which Ben was preparing marinara sauce (congruent) or dealing with an icy walkway (incongruent). ERP effects of global discourse congruence preceded those of local lexical association, suggesting an early influence of the global discourse representation on lexical processing, even in locally congruent contexts. Furthermore, effects of lexical association occurred earlier in the congruent than incongruent condition. These results differ from those that have been obtained in studies of reading, suggesting that the effects may be unique to spoken word recognition.
