q3 · i? · causal · r1

Controlled experiment with companies of men hearing shortened Human Reproduction commentaries; the abstract reports "equal learning" for the profile version versus the longer versions. No effect size is printed.

"The major finding of this study was that, with the film commentary of Human Reproduction there was equal learning for those hearing the shortest version--the profile vel~sion, as compared to the longer script writers' and full versions."
