Research has suggested that during reading, parafoveal information pertaining to the next word in a line might be, at least partially, processed. We used event-related brain potentials (ERPs) to examine this issue. Volunteers read sentences presented word-by-word at fixation with each word flanked bilaterally on its right by the next word in the sentence and on its left by the preceding word. Infrequently, the right flanker was replaced by a word that was semantically incongruous with the ongoing sentence context. N400 amplitudes to the critical triads were smaller when the right flanker was contextually congruent than incongruent, indicating that parafoveal information was extracted and quickly and incrementally integrated within the evolving sentence representation.
研究表明，在阅读过程中，与行中下一单词相关的旁视网膜信息可能会被部分处理。我们使用事件相关脑电位（ERPs）来研究这个问题。志愿者在注视时逐字阅读句子，每个单词的右侧和左侧都有句子中的下一个单词和上一个单词。很少情况下，右侧的旁视词会被一个与正在进行的句子语境语义不一致的单词所取代。当右侧的旁视词与语境一致时，对关键三组词的 N400 振幅会更小，这表明旁视网膜信息被提取出来，并在不断发展的句子表示中快速且逐渐地整合。
