초록

기능 자기공명영상 기법을 이용하여 한국인 피험자들의 한글 및 영어단어 인지에서 나타나는 두뇌활성화 패턴을 연구하였다. 연구의 주목적은 두 언어가 가진 형태적 차이에 의해 뇌의 활성화 영역이 달라지는지를 알아보는 것이었다. 동일한 의미의 쉬운 단어를 사용하여 실험을 진행하였고 뇌영상 정보를 얻었다. 실험 결과, 영어단어 인지의 경우 선행연구(Bookheimer, 2000)와 유사하게 뇌의 전반적인 영역에서 고른 활성화가 나타났다. 한글 단어 인지의 경우 영어 단어 인지와 유사하였지만, 전두엽 부분 중 BA 8 영역이 활성화되는 결과가 나타났다. 이 영역은 특수한 시각자극을 선택적으로 인지하는데 관여하고 있다고 알려져 있다(Halsband & Passingham, 1982). 본 연구의 결과는 한글이 가지고 있는 형태적 특징 (표음문자이지만 비선형 형태)이 BA 8영역을 활성화 한 것을 시사한다.

Abstract

Even though the Korean words, Hangul, are characterized as phonemes like other alphabetic languages, their shape resembles more morphemes like Chinese characters. The main purpose of the study is to explore the neural mechanisms of reading Hangul and alphabetic (english) words by Korean native speaker using functional magnetic resonance imaging technique. In the results of our study, the activation pattern of reading english words looked similar to those with other previous studies. The activation pattern of reading Hangul is underlying similar mechanisms with those of english words at the general level. The significanlty different activation was indicated in the BA 8 of the frontal lobe. This area is known to be relevant with nonverbal higher order control or speicific visuospatial analysis and we suggest that the recognition of specific surface form of Hangul might be related with this activation.
