초록

사춘기 이후에 제2언어(L2)로 한국어를 습득하기 시작한 중국인 후기 학습자(late learners) 중 중급 수준 이상의 한국어 능력을 갖춘 학습자들이 한국어 문장이해 과정에서 어떠한 인지신경기제에 의해 의미통합을 진행하는지를 사건관련전위(ERP, event-related potentials) 측정기법에 의해 확인하였다. 위반 패러다임을 이용한 ERP 실험 결과 형용사 수식어와 명사 사이의 국지적(local) 의미적합성 위반(*고장난 수프 (vs. 달콤한 수프))에 대해서는 아무런 ERP 성분도 검출되지 않은 반면, 목적어 명사와 술어 동사 사이의 전역적(global) 의미적합성 위반(*수프를 고쳤다 (vs. 수프를 끓였다))에 대해서는 N400과 P600의 이항적(biphasic) ERP 패턴이 검출되었으며, 두 가지 의미통합 과정이 상호작용하지 않는 것으로 확인되었다. 이러한 결과는 의미처리 능력이 전반적으로 원어민의 그것에 미치지 못하는 후기 제2언어 학습자들이 문장 계층구조의 상이한 위치에서 진행되는 국지적 의미통합과 전역적 의미통합을 동시에 관리, 조정하기 힘들며, 따라서 문장 전체의 의미 표상에 훨씬 더 중요한 논항구조(argument structure) 처리에 직결되는 전역적 의미통합에 전략적, 선택적으로 집중한다는 것을 보여준다.

Abstract

The present study investigated the cognitive mechanism underlying L2 semantic integration during sentence comprehension in Korean by Chinese late L2 learners. Using the violation paradigm, ERP responses of 17 intermediate level L2 learners of Korean were recorded, to local semantic incongruence between an adjective and a noun (*broken soup (vs. sweet soup)), and to global semantic incongruence between an object noun and a verb (*to repair soup (vs. to cook soup)) respectively. No ERP components reflecting the detection of semantic anomaly were observed in the local incongruence condition, whereas a biphasic N400 & P600 ERP pattern was elicited by the critical verb of the global incongruence condition. These results imply that the L2 learners investigated in the present study have largely dismissed the local integration, and concentrated rather on the global integration, which is inevitable for the grasp of the verb argument structure and hence much more important to represent the core meaning of the unfolding sentence. Based on this evidence, we argue that L2 learners might well adopt reasonable strategies for maximizing processing efficiency, although they need not be identical to those of native speakers at every stage of L2 development.
