This dissertation investigates processing of English and Japanese relative clause (RC) sentences by native speakers and second/foreign language (L2) learners. Particularly, the relationship between the sentence processing and individual differences in working memory (WM) capacity was examined. The main question addressed in this study is whether the performances of L2 learners in processing RCs are similar to those of native speakers depending on one's WM capacity.
Two major approaches regarding the processing of RCs have been proposed to account for the differences between the difficulty of the subject-gap and the object-gap sentences: the cost of resources taken up by temporary storage and integration when processing (Dependency Locality Theory; Gibson, 1998, 2000) and the depth of embedding of the extracted element (Structural Distance Hypothesis; O'Grady, 1987; O'Grady, Yamashita, Lee, Choo and Cho, 2000). This study also evaluated these two hypotheses and answers the question: To which hypothesis do the performances of L2 learners best correspond?
Fourteen English native speakers who were Japanese language learners and 14 Japanese native speakers who were English language learners participated in the experiment, which consisted of three parts: First language (L1) and L2 reading span tests, L1 and L2 self-paced moving window reading tasks, and a L2 proficiency test. The comprehension accuracy rates of the experimental sentences and individuals' residual reading times in each region of the RC sentence types were used for comparisons. Additionally, the individual participants' sentence reading patterns were examined, so what may have been invisible on the group level analyses were revealed.
The results of the experiments showed that (1) English object-gap sentences are more difficult to comprehend than English subject-gap sentences for both L1 native speakers and L2 learners, (2) Japanese subject-gap sentences are more difficult to comprehend than Japanese objec (open full item for complete abstract)
