Outline of Final Research Achievements

This study examined from a Multi-Competence viewpoint how bilinguals'cognition would vary according to linguistic knowledge of the two languages, age of acquisition and language usage, based on the results of various types of bilingual subjects in several experiments. The performances of Japanese users of English, Korean students in Japan, Japanese-English bilinguals adults and children, deaf signers of Japanese Sign Language were investigated in this study. The data collected were eye-movement, responses to emotion words, acquisition of reading and writing, fluency and laterality of two languages. The results suggest that appeared language conditions (i.e. proficiencies) are formed being affected by each bilingual's linguistic environment and experiences as well as current use of the two languages and cognitive processes are presumed to be established as an efficiently integrated form of the two language processes.
