Abstract
In two experiments text was horizontally advanced in discrete jumps of one or several characters at a time along a single line on a computer-controlled screen (i.e., the leading text display format). Experiment 1 showed that when the display rate was relatively fast or when the window size was relatively small, jump lengths of five character spaces resulted in higher comprehension than did one- or nine-character jump conditions. In Experiment 2 the text display rate was under either experimenter or subject control; results showed that permitting the subject to control the rate of text presentation did not improve reading comprehension. However, when the rate of text presentation was under the control of the subject, reading efficiency (Rate x Comprehension) improved with practice.
