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.

比较了传统的隐喻、反讽和文字语言处理。30 名右手参与者（21-34 岁）执行了顺序陈述 ERP 范式。与字面陈述相比，隐喻的左额前部晚期负慢波（LANSW，450-1000 毫秒）明显更大，反讽的视觉趋势更大。中央顶叶 N400（300-450 毫秒）和中央顶叶右主导的“晚期 N400”（450-600 毫秒）在统计和视觉上对隐喻的趋势更大。与文字陈述（eLORETA；450–1000 ms）相比，隐喻中的左 PCC 和左舌回活动显着更高。统计趋势表明隐喻和反讽中海马旁回活动较高。考虑到不断变化的处理技术和更新的语义冲突，讨论了 N400 结果。N400 晚期与“联想性”的结构有关。LANSW 与隐喻映射、框架转换过程、意义整合和记忆过程有关。讨论了 eLORETA 结果，考虑了隐喻映射、心理图像的创建、约定俗成、效价、记忆过程和发散思维。
