接続詞「だけど」の使用に見られる推論枠組みの利用とその発達

抄録

“Dakedo” is a conjunction which is used to connect the premise and its implication. The purpose of this study is to investigate the kind of implications derived from a premise through the conjunction “dakedo”, and the developmental change in its use. Students in 2nd, 4th, 6th, 8th grades, and university undergraduates participated in the study. In the first investigation, they were asked to fill the blanks after the premise+“dakedo”. In the second, they were asked to rate the use of “dakedo” if it was used properly in a sentence. The results showed that implications were made from the premise by logical conversion, pragmatic inference, analogical inference, and referring to the premise. Also, the results showed that the use of “dakedo” developed differently, that is, the use of “dakedo” with pragmatic inference and reference was acquired through elementary school, but the use of “dakedo” with logical conversion and analogical inference took more time to be acquired until the university level.
