In this investigation, we examine the contribution of intrinsic content density (ICD) to measures of expository text processing. In Studies 1 and 2, the factor structure of select text density metrics was examined and refined using two text samples (Ns = 150) randomly selected from an expository text corpus. Scores on the ICD measure based on the…

Investigates gerontological research literature to discover what is known about age deficiencies in cognitive processes which might adversely influence instructional text processing. Maintains that, on the basis of findings, tentative guidelines could be given on designing such manuals. Proposes follow-up research to gather more knowledge on the…

Two experiments with 188 college students investigated the facilitative effect of typographical signals such as underlining, headings, or other devices to help readers identify specific points. Results do not support a general facilitative effect of typographical signals but suggest that use of signals depends on the reader's strategic processing.…

Uses a cognitive processing perspective to revise fifth grade social studies texts, to describe those revisions, and to demonstrate their effects empirically. Finds that students reading the revised text recalled more material and answered more questions correctly than did those reading the original text. Concludes that a text-processing approach…
