采用事件相关电位(ERP)技术比较在语义违反范式下网络语言和标准汉语的语义加工差异。结果发现:(1)不管是网络语言还是标准汉语,相对于语义一致条件,语义不一致条件在400 ms诱发了一个更负的负成分,但网络语言的经典N400差异波具有更晚的潜伏期和更长的持续时间; (2)溯源结果发现,网络语言和标准汉语的经典N400差异波的早期和晚期的定位均分别定位于丘脑和前扣带回,表明N400延迟效应是由个体对网络语言相对低的流利度所致,反映了认知冲突的延续; (3)在语义一致性条件下,网络语言比标准汉语诱发了一个更负的新颖N400和一个更正的晚期正成分(LPC),分别定位于前扣带回和海马,二者分别反映了新颖网络...

Internet language is a creative product of the rapid development of computer-mediated communication. Previous studies showed that compared to standard language, Internet language induced a delayed and extended N400 effect. However, the classic N400 cannot interpret the cognitive processes of Internet language in daily life, because it is an artificial ERP component derived from the semantic incongruity. Alternatively, the processing of Internet language can be considered as a creative thinking process. Its neural processing may be similar to that of verbal creativities like metaphor and Chines...
