There were no significant facilitating effects to the retention of signaled information in the overuse of text signals condition, but there were in the selective use of text signals condition. Experiment 3, in which 2 small experiments contained, studied the effects of reader-based factors. Experiment 3a examined the effects of the familarity to the text topics and the readers' reading levels. Experiment 3b explored the effects of cognitive style and the intention to use the text signals. The results were as the follows: There were no significant difference between the signaled and unsignaled conditions in the circumstance of high familarity to the text topics, but there were significant differences between them in the circumstances of lower familarity to the text topics. There were no significant differences between the signaled and unsignaled conditions for the field-independent participants, but there were for the field-dependent participants. All the participants with different reading levels were helped by the text signals.
