Sound During Sleep Improves Learning
Research finds that sleeping after learning helped retain new information, especially if sound cues related to the information were played during sleep.
Subjects learned the positions of 50 objects on a computer screen - each picture paired with a unique sound. During sleep, scientists played the sound cues for half the images presented during the memory test. Subjects were better at placing the objects for which sound was played during sleep, even though none reported hearing anything.
