In two experiments saccade-related brain potentials (SRPs) to sentences were investigated under conditions approximating natural reading. Our aim was to look for electrophysiological (SRP) signs of sentence context on the processing of final words that were either congruent or incongruent with the meaning of the sentence. In Experiment 1 subjects indicated by a button-press whether or not the final word was congruent with the context, while in Experiment 2 they read silently without an overt decision. In Experiment 1, SRPs to incongruent words were more negative than SRPs to congruent words between 80-310 msec (from saccade offset). In Experiment 2, however, the inconcruent SRPs became more negative than the congruent SRPs only between 280-460 msec. These results suggest that in Experiment 1, during the processing of incongruent words the early sign of registering mismatch appears simultaneously with the analysis of the visual features of the word.
在两项实验中，在接近自然阅读的条件下研究了对句子的扫视相关脑电位（SRP）。我们的目的是寻找句子语境对句末单词加工产生影响的电生理（SRP）迹象，这些句末单词与句子意思要么一致，要么不一致。在实验1中，受试者通过按键来表明句末单词是否与语境一致，而在实验2中，他们默读句子且无需做出明显判断。在实验1中，在80 - 310毫秒（从扫视结束起）之间，对不一致单词的SRP比对一致单词的SRP更正。然而，在实验2中，不一致的SRP仅在280 - 460毫秒之间比一致的SRP更正。这些结果表明，在实验1中，在加工不一致单词的过程中，登记不匹配的早期迹象与对单词视觉特征的分析同时出现。
