Abstract

Most of participants are undergraduate or graduate students. They were asked to state their opinions and experiences in monologue style by answering ten questions prepared in advance. This study also describes the results obtained in a study which utilized the present corpus. This study demonstrated a tendency on the part of native speakers of Japanese, as well as Korean or Chinese-speaking learners of Japanese, to use the Japanese adverb Yappari in their statements.
