研究人员记录了18名正常成年人在阅读句子时的事件相关脑电位（ERPs），这些句子以字面、隐喻或中间字面映射条件下的单词结尾。在后一种情况下，单词的字面意义的使用方式促使读者从不同的领域映射概念结构。在句子结束词开始后300 - 500毫秒测量的erp随着隐喻性的变化而不同：字面结尾引起的N400最小，隐喻引起的N400最大，而字面映射引起的N400振幅中等。隐喻结尾也比字面或字面映射词引起更大的后验积极性。与概念融合理论一致，研究结果表明，概念整合的需求影响了字面语言和隐喻语言的难度。
Event-related brain potentials (ERPs) were recorded from 18 normal adults as they read sentences that ended with words used literally, metaphorically, or in an intermediate literal mapping condition. In the latter condition, the literal sense of the word was used in a way that prompted readers to map conceptual structure from a different domain. ERPs measured from 300 to 500 msec after the onset of the sentence-final words differed as a function of metaphoricity: Literal endings elicited the smallest N400, metaphors the largest N400, whereas literal mappings elicited an N400 of intermediate amplitude. Metaphoric endings also elicited a larger posterior positivity than did either literal or literal mapping words. Consistent with conceptual blending theory, the results suggest that the demands of conceptual integration affect the difficulty of both literal and metaphorical language.
