Abstract

Previous research suggests that executive control ability may contribute to second language (L2) metaphor comprehension, and this relationship may be modulated by metaphor familiarity. However, so far most studies have been done with behavioral experiments. Using the event-related potential (ERP) and standardized low-resolution brain electromagnetic tomography analysis (sLORETA), this study adopted the semantic priming paradigm to examine the role of executive control ability in L2 metaphor comprehension with different degrees of familiarity. The Stroop task was used to measure executive control ability and differentiate the two groups of participants who were presented with three types of word-pair expressions: familiar metaphoric expressions, unfamiliar metaphoric expressions and literal expressions. They were then asked to perform a semantic judgment task. Results revealed more negative amplitudes of N400 and P600 components in participants of low executive control compared with those of high executive control. Metaphor familiarity modulated N400 of both groups of high and low executive control, whereas it only affected P600 of participants of low executive control. sLORETA analysis of both N400 and P600 revealed stronger activation for the low versus high executive control group in the right superior frontal gyrus and middle frontal gyrus during low familiar metaphor comprehension. These results suggest that executive control plays a role in L2 metaphor comprehension, while it is modulated by metaphor familiarity.

执行控制能力在第二语言隐喻理解中的作用：来自 ERP 和 sLORETA 的证据

以往的研究表明，执行控制能力可能有助于第二语言（L2）的隐喻理解，而这种关系可能受到隐喻熟悉程度的调节。然而，迄今为止，大多数研究都是通过行为实验完成的。本研究利用事件相关电位（ERP）和标准化低分辨率脑电磁断层扫描分析（sLORETA），采用语义引物范式来考察执行控制能力在不同熟悉程度的第二语言隐喻理解中的作用。研究采用 Stroop 任务来测量执行控制能力，并对两组被试进行区分。然后要求他们完成一项语义判断任务。结果显示，与高执行控制能力者相比，低执行控制能力者的 N400 和 P600 分量的负振幅更大。对 N400 和 P600 的 sLORETA 分析表明，在低熟悉度隐喻理解过程中，低执行控制组与高执行控制组相比，右侧额上回和额叶中回的激活更强。这些结果表明，执行控制在 L2 隐喻理解中起着一定的作用，同时也受到隐喻熟悉程度的调节。

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.
