韓国人日本語学習者による終助詞「ね」の習得 ― 文法性判断テストとインタビューのデータから ―

Abstract

This paper analyzes the process of acquiring the final Japanese particle ne by different levels of Korean learners of Japanese through the theory of territory of information framework. Data of grammaticality judgement tests and interviews were gathered from learners as well as from native speakers of Japanese. Two versions of the tests were prepared with the same conversational scripts and were carried out three times in total, which was aimed to observe the stableness of their knowledge. In addition, the first two times of tests were with time pressure, and the third test was without it, which was to observe both of their implicit knowledge and explicit knowledge. The results of the third test, which was designed to measure explicit knowledge, shows the following. The percentage of correct answers of the advanced learners was lower than that of the learners of a lower level, for the type of optional ne in which the speaker does not have enough information, as well as for the inappropriate ne that should be omitted. It was also found out that the answers of the advanced learners to the three tests were less stable than learners of lower levels. The analysis of the interviews, however, shows that the advanced learners seem to capture subtle differences of various usages of ne than lower learners. The above-mentioned test results can be interpreted as caused by relatively precise but still uncertain perception of the advanced learners toward ne.
