Resumen de An experimental investigation of the effect of “previews” and “reviews” on retention of orally presented information
To test experimentally the efficacy of the advice that speakers should “preview” in the introduction and “review” in the conclusion the main ideas in the body of their speeches, each of four groups was presented a version of an audio‐taped speech on listening, identical for each group in all respects but one: group 1 heard the speech with preview only; group 2, preview and review; group 3, review only; and group 4, neither preview nor review. Analysis of scores on a multiple‐choice test of speech content revealed no significant differences between any of the groups.
