| Outline of Final Research Achievements |
The present study shows that although two group of participants of Chinese (morphemic) and Vietnamese (phonetic) native speakers had been matched in age of acquisition and Japanese language (L2) proficiency level and despite having no differences in behavioral performance (reaction time and accuracy) on demanded Japanese language tasks, which indicated there is no difference in their L2 proficiency level on task performance, there still were significantly different patterns of brain activities between them.
Our results strongly demonstrated that cultural difference of L1 influences how our brain processes the L2, not only the reading process but also the comprehension and speaking out. This in turn may reflect the nature of acquisition of L2 is a kind of skill of our human being, which can be interfered by educational strategies.

| Academic Significance and Societal Importance of the Research Achievements |
Unlike the native language (L1), which is considered to be an innate ability and acquired universally in the evolutionary process of human being, the nature of the second language (L2) is a kind of skill and the neural system involved in the operation of L2 may express the cultural influence of L1.
