초록
본 연구에서는 대학생들이 어려운 글과 쉬운 글을 읽는 동안에 안구운동을 측정하였다. 비교 분석은 전반적인 수준과 어절 수준에서 이루어졌다. 전반적인 수준을 보면, 평균 고정시간은 어려운 글을 읽을 때가 217ms로 쉬운 글을 읽을 때의 190ms에 비해 길었고, 도약거리는 어려운 글을 읽을 때가 3.7자로 쉬운 글을 읽을 때의 4.8자에 비해 짧았다. 어절 수준에서는 어려운 글의 단일 고정시간(single fixation time: 227ms)과 주시 시간(gaze duration: 266ms)이 쉬운 글(각각 195ms와 210ms)에서보다 더 길었다. 어려운 글과 쉬운 글 모두에서 단어 빈도 효과와 어절 길이 효과가 있었으며 빈도에 따른 고정시간의 차이와 길이에 따른 고정시간의 차이는 모두 어려운 글에서 더 크게 나타났다.
Abstract
This study investigated global and local characteristics of eye movement while 30 college students read easy and difficult Korean texts. It was found that readers who read the difficult text fixated longer for about 217ms and made shorter saccades of about 3.7 characters while readers who read the easy one fixated for about 190ms and made saccades of about 4.8 characters. Single fixation times and gaze durations in the difficult text were longer than those in the easy one(227ms vs. 195ms; 266ms vs. 210ms). In both easy and difficult texts, the effects of word frequency and eojeol length were found. In addition, the differences in fixation times according to word frequency and length were larger in the difficult text.
