This study was designed to provide methods on how to reduce the displeasure of Korean listeners in response to Japanese KFL learners facilitating adjunctive strategy in refusal situations. Through this study, it is possible to deliver meaningful messages on speech acts to the field of teaching and learning for Japanese KFL students. For this study, 60 Korean native speakers’ answer sheets were analysed. The statistics of questionnaires indicated that the displeasure difference is dependent on adjunctive strategy and the social status of the Korean listener, which means there is correlation between experimental and dependent variables. In case of using appellation as an adjunctive strategy, the degree of displeasure was lower than other cases. On the contrary, there was no statistical difference between using repeating a request strategy or not. Therefore, the result could emphasize that repeating a request as an adjunctive strategy would not help reduce the displeasure of Korean listeners in refusal situations. Especially, in the case where Korean listeners are of a higher social status, the differences of displeasure degree according to adjunctive strategies were significant in all situations. This means that appropriate adjunctive strategic uses are more attributable to Japanese KFL students communicating with Korean speakers who are of a higher social status. (Korea University)
