| Research Abstract |
The Japanese writing system has based both on kanji and kana components, in which the former has different functional properties as compared with the latter which is similar to Roman writing system, i.e., English, German and French, written with sound-based alphabetical symbols. The project aimed the comparative study of Japanese writing/reading system with that of Roman and Chinese system in terms of visual and verbal information processing. In addition, comparative study on low-vision system was done in both English and Japanese. Comparative study among different reading/writing systems was done by using reading span test (Japanese-, German-, French-versions) for measuring working memory capacity, by using Stroop test (Japanese-, German-, French-versions) for measuring verbal-perceptual information coding capacity, and by using low-vision test chart both for English and Japanese. Our results showed that although the writing system is likely differ to each language the working memory capacity is mostly unchanged. Furthermore, our Stroop scores revealed a sensitive index as for determining first- and second-language of bilingualists. We found Japanese low-vision subject need more sensitive screening letter chart for low-vision evaluation, especially kanji appears to require more higher spatial frequency component to detect correctly than kana which requires only 2-deg/character spatial frequency components.
