Conventional metaphor, irony, and literal language processing were compared. Thirty right-handed participants (21-34 years) performed a sequential-statement ERP-paradigm. A left-frontal Late Anterior Negative Slow Wave (LANSW, 450-1000 ms) was significantly greater for metaphors and by visual tendency greater for irony, compared to literal statements. A centroparietal N400 (300-450 ms) and a centroparietal right-dominant "Late N400" (450-600 ms) were by statistical and visual tendency greater for metaphors. Left PCC and left lingual gyrus activity was significantly higher in metaphors compared to literal statements (eLORETA; 450-1000 ms). A statistical trend indicated higher parahippocampal gyrus activity in metaphors and ironies. N400 results are discussed considering changing processing techniques and a renewed semantic conflict. The Late N400 was associated with the construct of "associativeness". The LANSW was related to metaphorical mapping, frame-shifting processes, integration of meanings, and memory processes. eLORETA results were discussed considering metaphorical mapping, creation of mental images, conventionality, valence, memory processes, and divergent thinking.
比较了常规隐喻、反讽和字面语言处理。 30 名右利手参与者（21-34 岁）进行了一个连续语句 ERP 范式。与字面陈述相比，隐喻会引起更大的左额前晚期负慢波（LANSW，450-1000ms），反讽则有视觉倾向引起更大的 LANSW。与隐喻相比，N400（300-450ms）和中央顶区右优势“晚期 N400”（450-600ms）更大。与字面陈述相比，隐喻在左后扣带回和左舌回引起了更高的脑区激活（eLORETA；450-1000ms）。统计趋势表明隐喻和反讽引起了海马旁回区更高的脑区激活。N400 结果考虑了加工技术的改变和重新出现的语义冲突。晚期 N400 与“联想性”的结构有关。LANSW 与隐喻映射、框架转移过程、意义整合和记忆过程有关。eLORETA 结果考虑了隐喻映射、心理意象的创建、常规性、情感、记忆过程和发散思维。
