We describe a new procedure using event-related brain potentials to investigate parafoveal word processing during sentence reading. Sentences were presented word by word at fixation, flanked 2° bilaterally by letter strings. Flanker strings were pseudowords, except for the third word in each sentence, which was flanked by either two pseudowords or a pseudoword and a word, one on each side. Flanker words were either semantically congruent or incongruent with the sentence context. P2 (175-375 ms) amplitudes were less positive for contextually incongruent than congruent flanker words but only with flanker words in the right visual field for English and in the left visual field in Hebrew. Flankered word presentation thus may be a suitable method for the electrophysiological study of parafoveal perception during sentence reading.
我们描述了一种使用事件相关脑电位来研究句子阅读过程中视上区单词处理的新方法。在注视点处,每个单词依次呈现,其两侧 2°处各有一个字母串。除了每个句子中的第三个单词外,所有的字母串都是伪词,而第三个单词两侧的字母串一侧是伪词,另一侧是单词。这些单词与句子的上下文要么语义一致,要么不一致。对于英语来说,在右视野中,对于希伯来语来说,在左视野中,语境不一致的侧翼词的 P2(175-375ms)振幅比语境一致的侧翼词的振幅要小。因此,呈现带有侧翼的单词可能是研究句子阅读过程中视上区感知的电生理方法。
