Variations in answering negative polar questions in Korean: An experimental study

With respect to how to answer polar questions, languages are taken to employ either the polarity-based system (e.g., English) or the truth-based one (e.g., Japanese). This dichotomy, however, is challenged when speakers make use of different negation forms and contextual information, particularly when answering negative polar questions (NPQs). This study investigates how two negation forms (short-form and long-form) and contextual bias affect the way speakers answer NPQs in Korean. The acceptability judgment experiment we conducted in this study shows that contextual bias, interacting with the negation form, often overrides the two-way distinction of answering systems. The results imply that a proper description of the variations in the Korean answering system to NPQs requires tight interactions among various grammatical components, including the discourse structure, rather than a syntax-based account that resorts solely to the syntactic structures of negation forms involved.
