초록

본 연구의 목적은 성인 독자들이 덩이글을 읽을 때, 글의 난이도와 독자들의 개인차 특성이 실시간 안구운동에 어떤 영향을 미치는지 알아보는 것이다. 실험 참여자들은 먼저 주어진 덩이글을 읽고 각 글의 핵심 주제를 묻는 질문에 답하였다. 그 후, 언어 능력, 단기 및 작업 기억 능력, 그리고 집행통제 능력을 측정할 수 있는 일련의 개인차 과제들을 수행하였다. 본 연구의 결과를 간단히 정리하면, 첫째, 글의 난이도는 읽기 속도에 부적인 영향을 주었다. 둘째, 독자들의 언어 및 인지 능력의 개인차가 글을 읽는 속도에 영향을 미쳤다. 즉, 언어능력이 높을수록, 단기 및 작업 기억의 용량이 클수록 글을 읽는 속도가 빨랐다. 그리고 글의 난이도와 개인차 변수 사이의 상호작용도 나타났는데, 언어 능력이 좋고, 작업 기억 용량이 클수록 읽기 속도에 대한 글의 난이도의 효과가 컸다 흥미롭게도 언어 능력이 좋고 작업 기억 용량이 큰 사람이 그렇지 않은 사람에 비해 쉬운 글을 읽는 속도가 훨씬 빨랐다. 하지만 이러한 능력들은 어려운 글을 읽는 속도에는 영향을 주지 않았다. 본 연구를 통해 얻은 결과와 관련된 이론적, 방법론적 쟁점들이 논의되었다.

Abstract

The purpose of this study is to investigate how text difficulty and readers’ individual differences in cognitive abilities affect eye movements while reading. Participants were asked to read given texts and to respond a question for each text. They were also administrated a battery of individual-difference tasks measuring abilities of language, short-term/working memory capacity, and executive control. The main findings were as follows. First, text difficulty negatively influenced on reading speed. Second, individual differences in language and cognitive abilities affected reading speed. Specifically, higher language ability and bigger capacity of short-term/working memory were associated with faster reading speed. Finally, interaction effects between text difficulty and individual differences were emerged such that those who had better language skills and bigger working memory size read easy texts faster than those who had not did. However, such abilities did not have effects on reading speed of difficult texts. Theoretical and methodological issues on the current findings were discussed.
