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.
