Abstract

Because a word is the basic unit of language processing, studies of the word recognition processing and the variables that contribute to word recognition processing are very important. Word frequency and word length are recognized as important factors on word recognition. This study examined the effects of those two variables on the Korean word recognition processing. In Experiment 1, two types of Hangul words, pure Hangul words and Hangul words with Hanja counterparts, were used to explore the frequency effects. A frequency effect was not observed for Hangul words with Hanja counterparts. In Experiment 2, the word length was manipulated to determine if the word length effect appears in Hangul words. Contrary to the expectation, one syllable words were processed more slowly than two syllable words. The possible explanations for these results and future research directions are discussed.

단어는 언어의 기초적인 의미 단위이기 때문에 단어재인에 대한 연구는 언어 연구에서 중요하며 단어처리에 기여하는 변인이 무엇인지에 관한 연구가 이루어져 왔다. 본 연구에서는 한국어 단어재인 과정의 주요 변인 중 단어 빈도와 단어길이의 영향을 탐색하였다. 먼저 단어 빈도와 관련하여, 한국어의 특징 중 하나인 한자어로 이루어진 단어에서도 기존의 연구와 동일한 양상의 빈도 효과가 나타나는지를 탐색하였다. 이를 위해 순 한글 단어와 한자어로 이루어진 단어를 비교하였으며, 그 결과 한자어로 이루어진 단어에서는 빈도 효과가 나타나지 않았다. 한편 단어 길이 효과의 경우, 단음절로 구성된 단어의 양상을 확인해 보고자, 음절의 개수를 변화시켜 단어 길이 효과를 측정하였다. 그 결과 단음절 단어는 이음절 단어에 비해 느리게 처리되었다. 특정 유형의 단어에 대한 빈도 효과의 부재 및 단음절 단어의 느린 처리는 한국어의 특징을 반영한 결과라 할 수 있으며 추후 연구를 통해 이에 대한 좀더 자세한 탐색이 필요할 것이다.
