摘要

尽管隐喻语言是日常生活中最常见的创造性表达方式之一,但人们对传统隐喻和新颖隐喻处理的神经认知机制并不完全了解。特别是,注意力在隐喻理解中的作用还缺乏研究。本研究的第一个目的是调查传统隐喻和新奇隐喻评价所产生的 N400 事件相关电位(ERP)成分。本研究的第二个目的是探索注意力网络(警觉、定向和执行控制)与传统隐喻和新隐喻评估产生的 N400 波幅之间的关联。受试者在进行隐喻评估任务时,会看到新颖的隐喻和传统的隐喻,同时会记录 ERPs。他们需要评估每个句子的新颖程度。此外,他们还进行了简短的注意力网络测试,以研究警觉、定向和执行控制这三种注意力网络。隐喻评价任务的行为结果显示,新颖的隐喻比传统的隐喻更慢、更新颖。ERP参数表明,与新隐喻相比,传统隐喻的N400达到峰值的时间更早。此外,与传统隐喻相比,新隐喻在 LH 上产生的振幅更大。此外,传统隐喻评价与注意网络无关,而新隐喻评价则与执行控制网络有关。研究结果表明,与传统隐喻评价相比,新隐喻评价与不同的认知需求相关,而且每种隐喻与注意力的相互作用也不尽相同。

N400 modulations in metaphor evaluation and its associations with attentional systems: A behavioral and ERP study

Although metaphoric language is one of the most common expressions of creativity in everyday life, the neurocognitive mechanisms underlying conventional and novel metaphor processing are not fully understood. In particular, the role of attention in metaphor comprehension is lacking. The first aim of this study was to investigate the N400 event-related potential (ERP) component produced by conventional metaphor and novel metaphor evaluation. The second aim of this study was to explore the associations between attentional networks (alerting, orienting, and executive control) and the N400 amplitudes produced by conventional and novel metaphor evaluation. The participants performed a metaphor evaluation task, in which novel and conventional metaphors were presented, while ERPs were recorded. They were required to evaluate how novel is each sentence. In addition, a short version of the attention network test was administered to investigate three attention networks, alerting, orienting, and executive control. The behavioral results of the metaphor evaluation task showed that novel metaphors were rated slower and as more novel than conventional metaphors. The ERP parameters indicated that the N400 peaked earlier for conventional metaphors compared to the novel metaphors. In addition, novel metaphors produced larger amplitudes over the LH compared to those evoked by the conventional metaphors. Moreover, while conventional metaphor evaluation was not associated with the attentional networks, novel metaphor evaluation was associated with the executive control network. The findings suggest that novel metaphor evaluation is associated with different cognitive demands compared to conventional metaphor evaluation, and each of the metaphors differently interacts with attention.

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.
