Despite a substantial literature on problems related to user navigation, we know remarkably little about the relationship between navigational strategies and successful use of hypertext. Revealing the complex interactions of navigational decision making and comprehension, however, will require objective, reliable, and empirically significant navigational metrics that go beyond the largely informal and indirect measures that have traditionally been used. The purpose of this paper is to describe a study that replicates and extends earlier work that defines and validates two objective navigational metrics [5]. Results of this study confirm the empirical significance of these metrics, support the reliability of their relationship to hypertext comprehension, and provide indirect support for a model of reading comprehension that postulates greater demands on higher-level processing in hypertext compared to traditional print.
