Sixty-six studies were reviewed that met several a priori criteria. Specifically, the studies had to be empirical investigations that related to a particular academic domain and that involved connected discourse presented either in traditional written form or on computer. In addition, the studies had to incorporate some measure of both knowledge and interest. The resulting body of literature was first summarized and analyzed in terms of the domains chosen, the subjects selected, the nature of the texts used, the manner in which knowledge and interest were assessed, and the principal outcomes reported. Next, from this analysis, six premises were proposed as guides for future research and practice. Finally, concluding remarks were advanced that address the overall significance of text-processing research that interactively considers the domain of knowledge and the interest of the reader.
