Memory Improves with Sleep
Sleep plays a crucial role 重要的 in better memory.
Christie Nicholson reports
Want to remember something?
finds that the more we value重視a piece of information the more likely we’ll review it during our sleep. And because we do that, we’ll tend to傾向於 remember it.
Participants were shown objects with different corresponding 符合的dollar amounts on a computer screen. If participants could remember that object later on a test, they were rewarded with the associated dollar amount. Objects were also accompanied by an associated sound, for instance a cat was accompanied by a “meow.”
After either a 90-minute nap小睡 or wake period醒來的時間, subjects’ memory for low-value objects was worse than for high-value objects.
In a second experiment associated sounds were played either when the subjects were awake or asleep, as a way to trigger觸發 the memory of the object.
Researchers found that low-value objects were better remembered when the associated sound was played during subjects’ sleep as opposed to 與…對照(而不是)when they were awake.
The authors believe that during sleep is when we tend to go over the day’s new information, so that is why they could manipulate操縱或運用 the memory storage記憶儲存 of lower-value objects during sleep time rather than wake time.
Gives new meaning to the term sound asleep.(原指熟睡，這邊是雙關語，睡眠中以聲音輔助記憶，也是一個加深印象的方式，睡眠時操作比醒著的時候效果還要來得好)
