项目摘要

One of the most fundamental and universal properties of human language is a phenomenon called displacement. We used multi-channel event-related potentials (ERPs) to identify the nature of this phenomenon with Japanese, an SOV language of relatively free word order. The ERPs of sentences of canonical word order (CC) were compared with those of non-canonical word order in two types of Japanese complex sentences ; namely in those which can be described as being in a middle-scrambled condition (MSC) and in those in a long-scrambled condition (LSC). The sustained anterior negativity (SAN) and the P600 in the pre-gap position were observed in the LSC, compared to the CC, and they are consistent with previous findings. The SAN, exhibiting a tripartite nature in morphology and scalp distribution, mainly reflected a storage cost of scrambled elements in sentence comprehension. The subsequent P600 had a left front-temporal maximum, distinguished from a posterior P600, taken as a reflector of the thematic role assignment in previous related studies. It is argued that the P600 in the present study reflects a cost of structural integration intensively depending on the case marker information. A compositional interpretation of sentence meanings was also observed, reflected in an anterior negativity at the post-gap verbal position, which cannot be differentiated at the pre-gap verbal position in the languages of SVO word order. The ERPs of sentences of right dislocated arguments were compared with those of the right dislocated adjuncts. It was found that right dislocated arguments elicited a left dominant positivity, reflecting a syntactic integration in sentence comprehension. The ERPs and the MEG investigated the processing of middle scrambled sentences. The large positivity with a left temporal maximum was elicited at the time window of 300-500ms, and the MEG also elicited an activation at around this time period.

人类语言最基本和最普遍的特性之一是一种称为位移的现象。我们使用多通道事件相关电位（ERPs），以确定这种现象的性质与日本，SOV语言的相对自由的词序。本研究比较了两种类型的日语复句中规范语序（CC）和非规范语序（LSC）的ERP，即处于中置乱状态（MSC）和处于长置乱状态（LSC）的ERP。与CC相比，LSC中观察到持续性前部负波（SAN）和前间隙位置的P600，它们与以前的研究结果一致。SAN在形态和头皮分布上呈现三分性，主要反映了句子理解中杂乱成分的存储成本。随后的P600有一个左前颞叶最大值，区别于后P600，作为一个反射器的主题角色分配在以前的相关研究。有观点认为，本研究中的P600反映了结构整合的成本，强烈依赖于案例标记信息。句子意义的组合解释也被观察到，反映在一个前否定在后间隙动词位置，这不能区分在前间隙动词位置的语言SVO语序。比较右移位论元和右移位论元句子的ERP。结果发现，右错位的论点引起了左主导的积极性，反映了句子理解的句法整合。事件相关电位和脑磁图考察了中置句的加工过程。在300- 500 ms的时间窗内，诱发了具有左颞最大值的大阳性，并且MEG也在该时间段附近诱发了激活。
