Park, Kihyo, & Nam, Yunju. 2020. The psychological reality of presupposition of “tto” in Korean negation types. Korean Journal of Linguistics, 45-4, 843-862. In this paper, we investigated the psychological reality on the presupposition projections of the long and short form negation in Korean, using the presupposition trigger ‘tto’. It has been argued that while the long-form negation allows both presuppositions of which the contents are positive and negative, the short-form negation does only the negative presupposition. However, there are few empirical studies on this issue based on experimental methods. To explore the presupposition processing in Korean with these methods, we conducted two experiments where the participants were asked to complete fragmented sentences and judge acceptability on them using the given context information. The results showed that the participants do allow negative presupposition for the long-form negation while it is unlikely that the negative one could be permitted for the short form negation. Moreover, the participants prefer negative presupposition to positive presupposition on the long-form negation that bears ambiguity given that the negation yields both positive and negative presupposition. The mixed-effects regression models revealed that the types of negation effect in both sentence completion and acceptability judgment tasks, the effect of the context, and the interaction effect between the context and the types of negation were significant the acceptability judgment task. Taken together, our results confirmed that those Korean presupposition projections could be recognized and represented as previously predicted by the past theoretical studies, thereby showing the psychological reality of these pragmatic phenomena in Korean speakers.
