Memories associated with a reward are preferentially reinforced by sleep. Even a short nap after a period of learning proves to be beneficial.

Lead researcher Kinga Igloi said, "Rewards may act as a kind of tag, sealing information in the brain during learning. During sleep, that information is favorably consolidated over information associated with a low reward and is transferred to areas of the brain associated with long-term memory. The findings are relevant for understanding the devastating effects that lack of sleep can have on achievement. We already knew that sleep helps strengthen memories, but we now also know that it helps people select and retain those that have a rewarding value."
The study will be published in eLife.
