The act of refusal takes place in everyday lives, but it has been discussed to be a difficult speech act for nonnative speakers. This study seeks to investigate Korean EFL learners' refusals in extended discourse along with their pragmatic perceptions. Sixteen college students were engaged in oral role-plays with two native English speakers and instructed to refuse the interlocutor's request. The refusal performances were analyzed using conversation analysis framework with respect to the interlocutors' different powers and the learners' proficiency levels. Learners also participated in retrospective verbal reports. Findings depict different verbal and nonverbal features illustrating learners' sensitivity towards higher status and their different linguistic abilities. Furthermore, their verbal reports revealed that despite their pragmatic awareness, learners were not fully equipped with appropriate L2 pragmatic knowledge.
