Abstract

This study investigated whether metaphors are predominantly processed in the right or left hemisphere when using Chinese and English metaphors in Chinese bilingual speakers. The role of familiarity in processing of metaphorical and literal expressions in both the first and second language was studied with brain-event-related potentials using a divided-visual-field paradigm. The participants were asked to perform plausibility judgments for Chinese (L1) and English (L2) familiar and unfamiliar metaphorical and literal sentences. The results obtained using parameter-free cluster permutation statistics suggest a different pattern of brain responses for metaphor processing in L1 and L2, and that both metaphoricity and familiarity have an effect on the brain response pattern of both Chinese and English metaphor processing. However, the brain responses were distributed bilaterally across hemispheres, suggesting no clear evidence for lateralization of processing of metaphorical meanings. This is inconsistent with the Graded Salience Hypothesis and Fine-Coarse Semantic Coding Theory, which posited a right hemisphere advantage of non-salient and coarse semantic processing.

中英双语者隐喻加工的半球优势:DVF和erp证据

本研究考察了汉语双语者在使用中英文隐喻时，隐喻主要是在右半球加工还是在左半球加工。本研究采用分视场范式，利用脑事件相关电位研究了熟悉度在第一语言和第二语言隐喻和字面表达加工中的作用。参与者被要求对汉语(第一语言)和英语(第二语言)熟悉和不熟悉的隐喻和字面句子进行合理性判断。无参数聚类排列统计结果表明，汉语和英语隐喻加工的脑反应模式不同，隐喻性和熟悉性对汉语和英语隐喻加工的脑反应模式都有影响。然而，大脑的反应分布在双侧半球，这表明没有明确的证据表明隐喻意义的处理是侧化的。这与分级显著性假设和精细粗糙语义编码理论不一致，后者假设右半球具有非显著性和粗糙语义加工的优势。

期刊介绍： The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
