摘　　要：本研究使用S1→S2范式研究中国人大脑隐喻加工模式是否与"等级显性理论"一致。被试对隐喻匹配任务和不相关匹配模式进行"是"和"否"隐喻的判断,同时脑电设备记录他们进行任务加工时的事件相关电位(ERP)。通过对相关电极N400的分析发现,右脑加工两个任务时,激活程度呈递增的趋势,与"等级显性理论"一致。另外,两个任务中顶叶空间加工区参与程度的差异说明,隐喻意义的整合需要对相似性、熟悉度等确定后再进行空间联系。In this research S1→S2 paradigm is used to test the consistency between the model of metaphor processing by Chinese and ＂graded salience hypothesis＂.The subjects are asked to make the ＂yes＂ or ＂no＂ judgment during matching tasks of metaphor pairs and unrelated pairs,while their brainwave ERPs are recorded.N400s at a number of electrodes are analyzed,which indicates that N400s at CP2,CP6,and P4 have significant difference.The results show that right hemisphere is involved in both the tasks and display a graded activation continuum which seems to be in consistency with Giora＇s theory.The involvement of parietal area during metaphor processing further proves Lakoff＇s spatial mapping theory of metaphor comprehension.The latency of the spatial involvement suggests that the generation of metaphor meaning is achieved in the spatial capacity only after similarity and familiarity of the objects are finalized.
