【摘要】：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含义的识别以及新颖语义信息的整合与新颖语义联结的形成。ERP结果支持了网络语言加工属于创造性思维过程。
[Abstract]:Event-related potential (ERP) technique was used to compare the semantic processing differences between network language and standard Chinese under semantic violation paradigm. Compared with semantic consistency condition, semantic inconsistency condition induces a more negative component at 400 Ms, but the classical N400 differential wave of network language has a later latency and longer duration. (2) tracing the results, we found that the early and late localization of the classical N400 differential waves in network language and standard Chinese were located in the thalamus and anterior cingulate gyrus, respectively. The results show that the N400 delay effect is caused by the relatively low fluency of individual in network language, which reflects the continuation of cognitive conflict. 3) under the condition of semantic consistency, network language induced a more negative novel N400 and a corrected late positive component, LPCP, which were located in the anterior cingulate gyrus and hippocampus, respectively. They reflect the recognition of novel network meanings, the integration of novel semantic information and the formation of novel semantic connections. The results of ERP support that the processing of network language belongs to the process of creative thinking.

【正文快照】： 1前言进入21世纪以来,互联网成为推动经济社会发展变迁的重要引擎,逐渐改变了人们的语言生活方式,网络语言应运而生。网络语言是指网民在即时通信平台、社交网站等地方常用的语言(Crystal,2001),如“月光族”、“木有”等。从产生开始,网络语言便受到了各个学科研究者的关注。
