摘要： Reading hypertext documents is more difficult than reading traditional linear text. Text highlighting plays the role of encoding for reading comprehension and may play the roles of contextual cues and landmarks for hypertext navigation. The purpose of this study was to examine the effect of text highlight and organizing highlighted text into a hierarchical structure on browsing, reading, and navigation performance in a network hypertext system. A randomized experiment was conducted. Ninety participants were randomly assigned to three conditions: a reading system with text highlighting, with text highlighting and organizing highlighted text, and without any aids. Dependent variables included browsing performance: time spent and the length of navigational path for reading; reading performance: recall and inference scores, navigational performance: scores of landmark and route knowledge and time spent and the length of navigational path for completing nine navigational tasks. The results showed that text highlight did not improve reading and navigational performance. By contrast, organizing highlighted text yielded significantly worst performance in reading and navigation. According to the results, we propose several suggestions for the design of reading instruction and digital highlighters. •Text highlighting may play the roles of contextual cues for navigation.•An experiment examined the effect of text highlight and organizing highlighted text.•Text highlighting did not improve reading and navigation performance.•Organizing highlighted text yielded the significantly lowest performance. 出版者： Elsevier Ltd 出版日期： 2016 出處： Computers in human behavior, 2016, Vol.54, p.318-325 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2015 Elsevier Ltd 識別號： ISSN: 0747-5632 識別號： EISSN: 1873-7692 識別號： DOI: 10.1016/j.chb.2015.08.012
