Using a combination of offline and online measures, we investigated the extent to which readers adhere to evidential consistency during incremental processing. Our findings indicate that while readers generate probabilistic expectations based on early cues, these expectations are distinctly modulated by semantic compatibility. The observation that evidential mismatches are frequently accommodated suggests that evidentiality in Korean functions as a soft constraint to prevent communication breakdown. We conclude that evidential processing is not driven by rigid grammatical algorithms but is a flexible mechanism that balances probabilistic expectation with semantic congruence. 2025-12-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/208174 Title: 대규모 언어 모델 기반 정보 이론적 복잡도 지표와 언어 처리의 신경 상관성 Authors: 김건; 남윤주 Abstract: This study explores the relationship between information-theoretic metrics from large language models and neural activity during natural sentence reading. Analyzing EEG data, we found that surprisal was associated with reduced lower-beta power during initial processing, reflecting updates to an existing predictive model. Furthermore, entropy correlated with increased broadband neural power, primarily over left-hemisphere regions. In contrast, entropy reduction was associated with increased high-beta and gamma power, linked to information integration. These findings demonstrate that different information-theoretic metrics map onto distinct neural signatures of predictive processing and cognitive load. While the results provide strong evidence for these links, the fixation-locked analysis method suggests a need for future research to capture the continuous, dynamic time-course of meaning integration. 2025-06-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/197926 Title: Variations in answering negative polar questions in Korean: An experimental study Authors: Kim, Jong-Bok; Kim, Jungsoo; Nam, Yunju Abstract: 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. 2024-10-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/195281 Title: 한국어 부사어 구문 문장 처리 연구: 모어 화자와 고급 학습자의 비교 Authors: 백준오; 정현정; 이선영; 남윤; 김영주 Abstract: 본 연구에서는 인지 동사를 사용한 한국어 부사격 조사 ‘-(으)로’ 구문 문장에서 형태･통사･의미적 정보가 처리되는 양상을 살펴보았다. 한국어 모어 화자(N=27)와 고급 학습자(N=27)를 대상으로 조사, 어순, 명사구 유정성 조건이 조작된 총 336개의 문장을 자가조절읽기 과제를 통해 처리하도록 하였고, 리커트 5점 척도 설문을 통해 이해 점검 수준 및 의미역 할당 성향을 확인하였다. 연구 결과, 모어 화자와 학습자 모두 ‘의미 < 통사 < 형태’ 순의 문장 처리 경향을 보여 형태적 정보인 조사를 최우선적으로 활용하는 것으로 나타났다. 이러한 결과는 제약성이 큰 부사격 문형이 학습자들에게 조사 민감도를 높이는 문장 처리 전략을 강하게 유도하기 때문으로, 학습자 집단의 숙달도가 모어 화자와 같기 때문은 아닌 것으로 나타났다. 세부 분석에서는 학습자 집단의 명사구 유정성에 대한 높은 의존도가 나타나서 명사구 대비 조건이 제약성이 큰 부사격 문형의 난이도를 조절할 수 있는 핵심 요인으로 나타났다.; This study investigates the processing patterns of morphemic, syntactic, and semantic information in sentences using the adverbial case marker ‘-(eu)ro’ and cognitive verbs. The study presented a total of 336 sentences to 27 native Korean speakers and 27 advanced learners, with variations in case markers, word order, and noun phrase animacy. Participants processed these sentences via a self-paced reading task and were evaluated for comprehension and semantic role assignment tendencies using a Likert 5-point scale survey. The findings revealed that both native speakers and learners exhibited a processing hierarchy of ‘semantics < syntax < morphology,’ prioritizing morphological information, specifically the case markers. This suggests that the restrictive nature of adverbial phrases compels learners to adopt sentence processing strategies that enhance sensitivity to case markers. However, a more detailed analysis indicated that learners still tended to depend on the animacy of noun phrases, reflecting that their proficiency level is not comparable to that of native speakers. The study highlights that variations in noun phrase animacy are crucial for adjusting the difficulty of highly constrained adverbial sentences. Consequently, a multifaceted approach is essential for a comprehensive understanding of how learners acquire adverbial sentences involving cognitive verbs. 2024-06-01T00:00:00Z
