Abstract
This study examines the brain activation of a left-handed, intermediate-level Japanese learner while they take written tests and make conversation. The written tasks were modeled based on the Japanese-Language Proficiency Test, and the brain data were collected using the fNIRS system. The participant was moderately left-handed, and the activation of the left and right hemispheres was confirmed in all tasks. Overall, the activation level for the written tasks was evidently lower than that for the conversation tasks. However, it was found that the sorting task may be closer to the conversation tasks because of its higher-level brain activation.
