In recent research, volunteers were given the words "bed," "drowsy," and "dream," and then 30 minutes later were asked what word they could remember. Those people who had attained over 4 hours of sleep the previous night were far more likely to make mention of the word "sleep;" they had synthesized that since the three words actually mentioned were all associated with the word "sleep," that it had been said. It is these associations, (even if they arguably can create "pseudolies") that ultimately can lead to creativity, and imagination.
This brings up the question: should we be thereby encouraging students to be sleeping less so they are truth-telling drones? Absolutely not. The entire mantra of creativity is how students can make discoveries and explore ideas. While I hope all parents and teachers enforce the belief that honesty is required, I find it difficult to believe that false memories, ultimately leading to a greater extent of creativity, have any moral detriment.
