Outline of Final Research Achievements

The present study investigated the effect of living in the target language country and that of the age factor on the acquisition of English by Japanese learners. Four subject groups participated in this study: native speakers of American English, Japanese returnees who had lived in the U.S., proficient learners and non-proficient learners who had never lived overseas. For measuring listening and reading abilities, we employed official TOEIC scores. We examined ISI durations, stressed vowel shortening and the quality of a weak vowel. We observed significant differences between the returnees and the proficient learners in listening abilities and the production of a weak vowel, but not in reading abilities and stressed vowel shortening. We also observed that the age factor had an effect on the different degrees of attainment of the production proficiency and on listening ability of the returnees, but not on their reading ability.
