Comprehension of conversational implicatures in L2 English
Abstract This study investigated the development of the ability to interpret conversational implicatures in English as an L2. The study followed a cross-sectional design and used a methodologically innovative audio-visual interpretation task with an oral production component. By orally reporting their interpretations, participants demonstrated comprehension of conversational implicatures viewed in a video, rather than employing a predetermined response approach used in earlier studies, which neither explore nor reveal how L2 learners understand implicatures. Fifty participants, forty-five learners at three proficiency levels and five native speakers of English, took part in the study. The results indicated that the comprehension of conversational implicatures showed a significant improvement as L2 proficiency increased. Learner responses were additionally coded based on stages of implicature calculation, which demonstrated that not only learners’ correct interpretations but also their incorrect responses provide insights into their interlanguage development. Such a finding further illustrates the superiority of a free response approach over a predetermined one since the former approach can better shed light on L2 learners’ true pragmatic competence in conversational implicatures.
