Abstract:
Abstract Eye movements have been utilized as an index of attention and comprehension during reading from a wide range of literature. In this study, eye-fixation sequence was recorded when participants were reading expository science text. Comprehension depth of the texts was evaluated via individual textual knowledge structure generated by Pathfinder, which has been suggested to serve as a salient reflection of knowledge representation. Although both eye-movements and textual knowledge structure have been proven to reflect reader’s comprehension skill, no research has been done yet to draw the link directly between them. The current study is aimed at predicting readers’ comprehension ability from their textual knowledge structure constructed by eye-fixation sequence. Due to limitations of presentation, measurement, and potential parafoveal processing, current results have not yet reached a significant level to support the proposed hypothesis.
