事件相关脑电位（ERP）从26个头皮网站被用来调查是否或不，如果是这样的话，在何种程度上的大脑过程subserving的理解可成像的书面文字和线条画是相同的。这些句子一个词一个词地呈现给28名大学生，让他们理解。每个句子都以一个书面单词（规则句子）或一个线条画（变戏法句子）结束，使它在语义上一致或不一致。对于一半的主题，定期和rebus句子随机混合，而对于其余一半的定期和rebus句子在单独的块（在两种情况下提供受试者内比较）。在这两种呈现格式中，单词和线条画在ERP中刺激后325和475毫秒之间产生了更大的消极性，相对于一致的句子结尾（即，N400类效应）。虽然这种消极情绪的时间过程对于文字和图片来说非常相似，但它们的头皮分布有显著差异;特别是，文字的经典N400效应比图片的大。图片的一致性效应，但不是文字也与较长的时间（较低的频率）的正面网站的负面。此外，在混合呈现模式下，N400效应对于图片比对于文字早达到约30毫秒的峰值。总而言之，数据表明，书面文字和图片在结束句子时的处理方式是相似的，但至少是由部分不重叠的大脑区域进行的。
Event-related brain potentials (ERPs) from 26 scalp sites were used to investigate whether or not and, if so, the extent to which the brain processes subserving the understanding of imageable written words and line drawings are identical. Sentences were presented one word at a time to 28 undergraduates for comprehension. Each sentence ended with either a written word (regular sentences) or with a line drawing (rebus sentences) that rendered it semantically congruous or semantically incongruous. For half of the subjects regular and rebus sentences were randomly intermixed whereas for the remaining half the regular and rebus sentences were presented in separate blocks (affording within-subject comparisons in both cases). In both presentation formats, words and line drawings generated greater negativity between 325 and 475 msec post-stimulus in ERPs to incongruous relative to congruous sentence endings (i.e., an N400-like effect). While the time course of this negativity was remarkably similar for words and pictures, there were notable differences in their scalp distributions; specifically, the classic N400 effect for words was larger posteriorly than it was for pictures. The congruity effect for pictures but not for words was also associated with a longer duration (lower frequency) negativity over frontal sites. In addition, under the mixed presentation mode, the N400 effect peaked about 30 msec earlier for pictures than for words. All in all, the data suggest that written words and pictures when they terminate sentences are processed similarly but by at least partially nonoverlapping brain areas.
