한국어 체언어절과 용언어절 재인에 관련된 어휘 변인 = Lexical Factors that Influence the Korean Eojeol Recognition

다국어 초록 (Multilingual Abstract)

Despite morphologically complex Korean word Eojeol has its own unique linguistic properties, the research interest related to this topic has been relatively little. Therefore, this study investigates the difference of the recognition process in the Korean Eojeol by significant lexical factors. Two main classes of this study which are used for experiment 1 and 2 are a noun Eojeol and the predicate (verb and adjective) Eojeol. The Eojeol decision task was performed for both experiments, and their reaction time was analyzed by multiple regression analysis. For the experiment 1 (noun Eojeol), the lexical factors of ‘whole Eojeol frequency’, ‘root frequency’, and ‘first syllable sharing frequency’ are predicted as the most effective predictors for the Eojeol recognition time. For experiment 2(the predicate Eojeol), by contrast, the ‘whole Eojeol frequency’ and ‘number of subjective meaning’ factors were predicted for the reaction time of the Eojeol recognition. With these results, we discussed the importance of its common and different significant lexical variables.

국문 초록 (Abstract)

형태소적으로 복잡한 구성을 가진 어절은 한국어 문장을 구성하는 단위로서, 일반 단어와는 구별되는 뚜렷한 차이점이 있음에도 불구하고, 그 처리과정에 대한 관심은 상대적으로 부족하였다. 본 연구는 한국어 문장에서 각각 주어와 서술어를 담당하는 체언어절과 용언어절의 재인에 미치는 어휘 변인의 차이를 조사하였다. 실험 1에서는 한국어 체언어절, 실험 2에서는 용언어절 재인에 영향을 미치는 예측 변인을 어절판단과제(Eojeol Decision Task, 이하 EDT)로 측정한 반응시간과의 회귀분석으로 도출하였다. 실험 1의 결과, “어절빈도”, ‘원형빈도’, 그리고 “첫음절빈도” 예측 변인이 체언어절의 재인 시간을 유의미하게 예측하는 것으로 나타났고, 실험 2의 결과 “어절빈도”와 “주관적 의미 수” 예측 변인이 유의미한 설명력을 가지는 것으로 조사되었으며, 예측 변인 간의 상호작용은 실험 2의 용언 어절의 예측 변인 간에만 유의미하게 조사되었다. 이에 본 연구 결과를 바탕으로 공통으로 나타난 어절빈도가 가지는 의미와 각 어절에 따라서 설명력이 유의미한 어휘 변인이 다르게 나타난 결과를 논의하였다.
