Effects of Typological Properties on Sentence Processing in Japanese

对自由语序、格助词和复合谓词的存在对日语句子加工的影响进行了实验和理论研究。首先，我们考察了格助词类型的差异对日语花园小路句加工的影响。我们测量了在移动窗口中视觉呈现的日语花园小路句子的阅读时间。这些句子包含的名词短语需要重新分析格助词-ga、(主格)和-ni(与格)标记的名词短语。中期结果表明，格助词差异对花园小径句的阅读时间没有显著影响。其次，我们考察了词序在移动窗口中视觉呈现的日语句子加工中的作用。我们发现，虽然语序对阅读时间没有显著的影响，但对词汇判断的错误率有显著的影响。这项研究的结果被接受并发表在《心理语言学研究》杂志上。第三，从日汉复合动词对比的角度对日语复合谓词进行了理论研究。这一研究结果已在加州大学欧文分校举行的国际汉语语言学协会第十届会议上公布(这项研究的一部分以Fukui和Sakai发表，待发表)。最后，在九州大学举行的日本语言学会第123届会议上，对理论语言学家和认知心理学家的联合研究提出了看法。

Both experimental and theoretical researches were conducted on the effects of free word order, existence of case-particles, and existence of complex predicates on Japanese sentence processing. First, we investigated into effects of differences in types of case-particles on processing of Japanese garden-path sentences. We measured reading time of Japanese garden-path sentences visually-presented in moving windows. The sentences contained noun phrases that required reanalysis of noun phrases marked by the caseparticle -ga, (nominative) and -ni (dative). The interim result indicated that there was no significant effects of case-particle differences on reading time of garden-path sentences. Second, we investigate into effects of word order in processing of Japanese sentences visually-presented in moving windows. We find that, though word order did not have significant effects on reading time, significant effects was observed on error-rates in lexical decision. The result of this research was accepted for publication in Journal of Psycholinguistic research. Third, theoretical researches on Japanese complex predicate was conducted from the point of view of contrastive study of complex verbs in Japanese and Chinese. The result was presented at the 10^<th> meeting of international association of Chinese Linguistics at University of California, Irvine (part of this research was published as Fukui and Sakai, to appear). Finally, perspectives of joint researches between theoretical linguists and cognitive psychologists that emerged from the experience of this research project was presented at the symposium of the 123^<rd> meeting of Japanese Linguistic Society at Kyushu University.
