摘要

摘要:研究发现汉语主语提取关系分句与宾语提取关系分句之间存在加工不对称性。尽管如此,对于SRC-ORC不对称是如何发生的还没有达成共识。因此,为了阐明神经活动如何以事件相关电位(ERPs)和脑振荡(即事件相关同步/去同步,ERS/ERD)的形式与不同处理难度的句子相协调,我们进行了脑电图(EEG)研究,以检验汉语SRCs和ORCs的理解程度。结果表明,在比较src和ORCs时,存在N400和P600效应。同时,在处理两种类型的关系分句时,δ ERS与N400相关,在处理SRCs时,δ ERS与P600相关。通过结合ERP和ERS指标,我们提出句子理解中整合和检索努力之间的分离可能是句子加工不对称的原因。关键词:事件相关电位(ERPs)delta/theta同步记忆检索整合句子理解披露陈述作者未报告潜在的利益冲突。本研究得到上海市教委和上海市教育发展基金会的支持[资助号:WBH4307002]。

Event-related potentials and brain oscillations reflect unbalanced allocation of retrieval and integration efforts in sentence comprehension
ABSTRACTEmpirical studies have found a processing asymmetry between Chinese subject-extracted relative clauses (SRCs) and object-extracted relative clauses (ORCs). Still, there is no consensus on how this SRC-ORC asymmetry occurs. Thus, aiming to elucidate how the neural activity, in the forms of both event-related potentials (ERPs) and brain oscillations (i.e. event-related synchronisation/desynchronisation, ERS/ERD), attuned to sentences with different levels of processing difficulty, we conducted an electroencephalography (EEG) study to examine the comprehension of Chinese SRCs and ORCs. The results showed an N400 and a P600 effect when comparing SRCs and ORCs. Simultaneously, delta ERS was associated with N400 during the processing of both types of relative clauses and theta ERS with P600 during the processing of SRCs. By incorporating the ERP and ERS indexes, we propose that the dissociation between the integration and retrieval effort involved in sentence comprehension may account for the processing asymmetry between sentences.KEYWORDS: Event-related potentials (ERPs)delta/theta synchronisationmemory retrievalintegrationsentence comprehension Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by Shanghai Municipal Education Commission and Shanghai Educational Development Foundation [grant number: WBH4307002].

期刊介绍: Language, Cognition and Neuroscience (formerly titled Language and Cognitive Processes) publishes high-quality papers taking an interdisciplinary approach to the study of brain and language, and promotes studies that integrate cognitive theoretical accounts of language and its neural bases. We publish both high quality, theoretically-motivated cognitive behavioural studies of language function, and papers which integrate cognitive theoretical accounts of language with its neurobiological foundations. The study of language function from a cognitive neuroscience perspective has attracted intensive research interest over the last 20 years, and the development of neuroscience methodologies has significantly broadened the empirical scope of all language research. Both hemodynamic imaging and electrophysiological approaches provide new perspectives on the representation and processing of language, and place important constraints on the development of theoretical accounts of language function and its neurobiological context.
