项目摘要

We have employed the so-called Dual Mechanism Model as our working hypothesis, which claims that two different mental/neurological mechanisms of memory and computation are involved in the processing of words, and conducted an ERP (Event-Related Potentials) experiment to investigate the processing of Japanese complex predicates at the neurological level. Our findings are as follows.We used two types of causative constructions, lexical causative (LC) and sase-causative (SC), and observed the ERP responses to unacceptable sentences (ULC:^*kansei-o narab-e-ru 'arrange shouts of joy', USC:^*ryoori-o narab-ase-ru 'make dishes line up') in comparison to the acceptable counterparts (ALC: ryoori-o narab-e-ru 'arrange dishes', ASC: senshu-o narab-ase-ru 'make players line up'). The ULC sentences elicited a typical N400, which we interpret to reflect the semantic selectional violations. In contrast, the USC sentences elicited an AN (anterior negativity) followed by an N400. The AN can be taken to reflect the computational process involved in detecting the ill-formedness of the USC sentences, while the following N400 is a reflection of the semantic violation. In addition, when the two acceptable sentence types (ALC and ASC) were compared, it was observed that the ASC elicited a P600, which we interpret to reflect the cost of syntactic computation involved in processing the bi-clausal structure of SC sentences. Thus our results basically support the Dual Mechanism approach to causative constructions, LC involving memory-based processing while SC being processed by syntactic computation.We have conducted another experiment, in the hope of accumulating basic ERP data on language processing in Japanese, exploring what ERP components are observed in case violations. We observed N400 for the violation of lexically specified case array of verbs (^*kodomo-ni shikaru 'scold a child', ^*hito-o butsukaru 'hit a person').

我们已经采用了所谓的双重机制模型作为我们的工作假设，该假设声称，记忆和计算的两种心理/神经系统机制参与了单词的处理，并进行了ERP（事件相关的电位）实验，以研究神经系统上日本复杂谓词的处理。我们的发现如下。我们使用了两种类型的病因结构：词汇诱使（LC）和Sase-Cusative（SC），并观察到ERP对不可接受的句子的响应（ULC：^*kansei-o narab-e-ru'安排欢乐的喊叫' （ALC：Ryoori-o narab-e-ru'安排菜肴'，ASC：Senshu-o Narab-ase-Ru'使玩家排队'）。 ULC句子引起了典型的N400，我们将其解释为反映语义选择的违规行为。相比之下，USC句子引起了AN（前面的），其次是N400。可以采用A来反映涉及检测USC句子不正确的计算过程，而以下N400是对语义违规的反映。另外，当比较两种可接受的句子类型（ALC和ASC）时，观察到ASC引起了P600，我们将其解释为反映了处理SC句子的Bi-Clausal结构所涉及的句法计算成本。因此，我们的结果基本上支持了偶性构造的双重机制方法，LC涉及基于内存的处理，同时由句法计算处理SC。我们进行了另一项实验，希望积累日语中语言处理的基本ERP数据，并探索在情况下观察到的ERP组件。我们观察到N400是因为违反了词汇指定的动词阵列（ ^*kodomo-ni shikaru'责骂孩子'， ^*hito-o butsukaru'击中一个人'）。
