읽기초기과정의 음운부호화 = Early Phonological Coding in Reading

다국어 초록 (Multilingual Abstract)

In this article, I discuss phonological coding in early stages of reading. The temporal loci of early phonological coding and lexical influence are discussed with focus on experimental evidence from priming paradigm and backward masking paradigm studies. Evidence in word processing in isolation and in sentence context shows that phonologcial effects with word homophones appear earlier than those with nonword homophones. Further, word frequency modulates phonological effects: most homophone effects observed as early as 30-35ms from the stimulus onset were confined to high-frequency words. Theoretical accounts for the early phonological effects are pursued, and lexical-phonological interaction is discussed with focus on cooperative function.

국문 초록 (Abstract)

본 논문에서는 읽기초기과정의 음운부호화를 다루고 있다. 점화기법이나 후차폐기법을 사용해 읽기초기단계의 음운효과를 측정한 실험 결과들을 살펴보고, 그를 토대로 읽기 초기에 빠르게 활성화되는 음운정보의 성격을 시간적 속성과 어휘적 관련성을 중심으로 논의하였다. 실험적 증거들은 단일한 단어처리와 문장 내 단어처리 모두에서 일관적으로 동음단어의 음운효과가 동음비단어의 음운효과보다 빠르게 나타남을 보여주고 있다. 또한, 단어빈도는 빠른 음운효과의 출현에 중요한 역할을 했는데, 30-35ms상의 음운효과는 고빈도 단어에 한해서 나타나는 경향이 컸다. 읽기초기과정에 관찰되는 빠른 음운효과에 대해 각 이론적 관점에서 어떤 설명이 가능한지 탐색하고, 음운-어휘 상호작용의 협조적 기능에 대해 논의하였다.
