―131―A neuro-psycholinguistic perspective on language processing □□□□□□□□□□□□□□□□□□□□□□□□□□□□□Kexin Xiong (Creative Interdisciplinary Research Division□Human and Society) The Japanese language is special because it employs two distinct writing systems: the logographic script, which uses characters to represent words rather than sounds, and the syllabic script, which represents sounds (morae or syllables) rather than meaning. Investigating the mechanisms of Japanese lexical processing from a neuro-psycholinguistic perspective is crucial for advancing our understanding of the complexities of human language processing, with implications for education and cognitive science. In the past academic year, we investigated the mental representations of logographic reading in Chinese-Japanese bilinguals [1][2] and analyzed the brain activities associated with reading syllabic words by Japanese native speakers [3]. We found that Chinese-Japanese bilinguals rely on the orthographic form of logographic words, and that phonological information is activated even when it is not necessary for visual word recognition in logographic reading. Additionally, we found that the time course of phonological activation in syllabic reading differs from that observed in alphabet reading.
