Using a reading task, the present study investigated saccade-related brain potentials (SRPs) accompanying the perception of the final words of proverbs, i.e. of sentences where the context allows a strong anticipation of the final word. The sentences were presented one at a time on a TV monitor. The proverbs appeared either in their original form or with their final word changed to be incongruous with the sentence context. SRPs to the two types of final words were recorded from 4 scalp areas. The onset of the saccade leading to the final word was used to trigger the averaging of SRPs. Incongruent and congruent brain responses were also compared by means of difference waveforms. The results showed that a difference between SRPs to congruous vs incongruous final words of proverbs already appeared simultaneously with the SRP component indicating the analysis of the visual pattern of the word. This finding supports an interactive model of word perception.
本研究通过一项阅读任务，调查了与扫视相关的脑电活动（SRP），这些活动伴随着对谚语最后一个词的感知，即对那些上下文能强烈预示最后一个词的句子的感知。句子一次一个地呈现在电视屏幕上。谚语要么以其原始形式呈现，要么将其最后一个词改为与句子上下文不一致的词。从4个头皮区域记录了对这两种类型最后一个词的SRP。导致看向最后一个词的扫视起始点被用于触发SRP的平均。还通过差异波形比较了不一致和一致的脑反应。结果表明，与谚语中一致和不一致的最后一个词相关的SRP之间的差异，在表明对单词视觉模式进行分析的SRP成分出现的同时就已经出现了。这一发现支持了单词感知的交互模型。
