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.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
