초록

본 연구에서는 한글 시각 단어재인 과정에서 이웃 단어의 역할을 알아보기 위해 두 개의 실험이 수행되었다. 기존 연구에 따르면 단어재인 과정에 단어의 빈도가 중요한 역할을 하며, 목표 단어와 철자 혹은 음운 정보가 유사한 이웃 단어도 중요한 역할을 하는 변인으로 알려져 있다. 한글에 대한 기존 연구에서는 주로 첫 음절을 공유하는 단어를 이웃 단어로 정의하고, 이웃 빈도는 크게 이웃 단어들의 수를 의미하는 타입 빈도와 이웃 단어들의 누적 빈도 합을 의미하는 토큰 빈도로 분류한다. 기존의 한글 단어재인 연구에서 단어 빈도 효과의 존재는 잘 알려져 있으나, 요인설계를 통해 두 종류의 음절 이웃 빈도 효과를 검증한 연구는 드물다. 본 연구는 한글 단어재인 과정에 이웃 단어가 어떤 영향을 주는지 알아보기 위하여 실험 1에서는 타입 빈도를 조작하였고, 실험 2에서는 토큰 빈도를 조작하였다. 어휘 판단 과제를 실시한 결과 음절 이웃의 타입 빈도와 토큰 빈도는 어휘 판단의 반응 시간에 영향을 미치지 않았다. 이에 본 연구는 한글 단어재인 과정에서 음절 기반 이웃 단어 효과의 본질과 특성에 대한 심도 깊은 논의의 필요성을 제안한다.

Abstract

In the present study, two experiments were conducted to examine how neighbor words affect Korean visual word recognition. Previous studies have shown that word frequency has a crucial role in word recognition. In addition, some researchers argue that neighbor words that are orthographically or phonologically similar to a target word also affect word recognition. In Korean, neighbor words can be defined as a group of words that share the first syllable with the target word. The type frequency of the syllabic neighbor words refers to the number of neighbor words and the token frequency refers to the accumulated word frequency of the neighbor words. Although previous studies on Korean visual word recognition have shown that the word frequency effect emerges, there are few studies on effects of the type or the token frequency using a factorial design. To this end, we conducted a lexical decision task, in which the type frequency was manipulated in Experiment 1 and the token frequency was manipulated in Experiment 2. The results showed that neither the type nor the token frequency affect response times of the lexical decision task. The results suggest the necessity to further discuss the nature and the characteristics on the effect of syllabic neighbor words in Korean visual word recognition.
