The purpose of this study was to investigate how text formats affect readers' recall and feeling of disorientation based on their working memory capacities and past experience with hypertext. A post-test only experiment was conducted. A new hybrid hypertext, expanding hypertext, was proposed and tested with 201 college students. Among the participants who were low in hypertext experience, those who read the expanding hypertext reported the least disorientation whereas those who read the paged hypertext reported the most disorientation. Of the participants with more hypertext experience, those who read the paged hypertext reported the least disorientation while those who read the scrolling text reported the most disorientation. Of the participants who were low in working memory capacity, those who read the scrolling text produced higher recall scores than those who read the paged hypertext. The text formats appeared to influence how much time the participants spent reading the texts and in turn affected the participants' recall scores.
