《中英對照讀新聞》Can You Learn Anything While You Sleep? 睡著時能學東西嗎？
Is sleep learning possible? The answer is yes and no, depending on what we mean by "learning."
Absorbing complex information or picking up a new skill from scratch by, say, listening to an audio recording during sleep is almost certainly impossible. But research shows that the sleeping brain is far from idle and that some forms of learning can happen.
The first study to demonstrate a memory and learning benefit from sleep was published in 1914 by German psychologist Rosa Heine. She found that learning new material in the evening before sleep results in better recall compared to learning during the day.
In recent years, multiple studies have found that a basic form of learning, called conditioning, can happen during sleep. In a 2012 study published in the journal Nature Neuroscience, Israeli researchers found that people can learn to associate sounds with odors during sleep.
Although the memory was implicit, it could affect the people’s behavior, researchers found in a 2014 study published in the Journal of Neuroscience.
