Reaction time to reading sentences which were not clearly interrelated was longer when a paragraph was titled to give it to more discourse (paragraph) level meaning. The presence of titles had no effect on reaction times for meaningful paragraphs, however. (CP)

A target paragraph was embedded in one passage where the target was of major importance, and one where it was of minor importance. Free recall, reading time, and usage of cognitive capacity were measured. There was greater recall when the target was important. The selective-attention hypothesis was not supported. (Author/GDC)

Three experiments, in which subjects read passages of variable readability, measured "cognitive capacity usage" (the attention level to reading material) by recording by subjects reaction times in a secondary task (responding to a "click"). The data indicated that the easy texts filled cognitive capacity more completely than the difficult texts,…
