Even facts "forgotten" by people during a busy day may be retrieved if this is followed by a good night's sleep.
如果晚上睡個好覺，即使白天由於忙碌而“遺忘”的一些事情也可以重新回憶起來。

Researchers from the University of Chicago asked volunteers to remember simple words.
芝加哥大學的研究者們要求志願者們記住一些簡單的單詞。

Many found their memories letting them down towards the end of the day, but the following morning, those who had slept well could recall much more.
到了晚上，許多人對自己的記憶力都感到失望。但是第二天早晨，那些睡得好的人能回想起來更多的單詞。

Researchers, writing in the journal Nature, said the brain could "rescue" lost memories during the night.
研究者們在《自然》雜誌發表論文說：大腦可以在晚間“修復”失去的記憶。

When the brain is first asked to remember something, that memory is laid down in an "unstable" state, meaning that it is possible that it could be lost.
當大腦最初被要求記住一些東西時，那段記憶處於一種“不穩定的”狀態，這意味著它很可能會丟失。

At some point, the brain consolidates those it deems important into a "stable", more permanent state.
在有些時刻，大腦會將那些它認為重要的記憶強化為“穩定的”狀態，也就是更持久的狀態。

However, the Chicago researchers suggested that it was possible for a "stable" memory to be made "unstable" again.
然而，芝加哥大學的研究者們提示說“穩定的”記憶也可能會轉變為“不穩定的”。

This would mean that memories could be modified then filed away again in the face of new experiences.
這就意味著當遇到新的情況時，記憶可能會被修改，隨後重新排列。

The 12 volunteers tested in the experiment were played words created through a speech synthesizer which were purposely difficult to understand.
參加試驗的12名志願者收聽了通過語音合成器產生的特別難懂的單詞。

Initially, the written version of the word was available, but afterwards the volunteers were asked to identify the word from the audio version only.
剛開始還給志願者提供單詞腳本，但是後來就要求他們僅僅通過聲音來辨別單詞。

Tests revealed that the ability to recall the right word tended to tail off as the day ended.
實驗顯示：一天快結束的時候，準確回憶單詞的能力隨之減弱。

However, when the volunteers were retested after a good night's sleep, they were able to recall some words that they had "forgotten" the previous evening.
然而，當志願者們睡了個好覺過後再次接受測試的時候，他們能夠回憶起一些他們前一天晚上已經“遺忘”的單詞。

Dr Daniel, one of the study authors, said: "Sleep consolidates memories, protecting them against subsequent interference or decay."
這篇論文的一位作者丹尼爾博士說：“睡眠可以鞏固記憶，防止它們隨後受到幹擾或衰減。”

"Sleep also appears to 'recover' or restore memories."
“睡眠看來也可以恢復記憶。”

He said: "If performance is reduced by decay, sleep might actively recover what has been lost."
他說：“如果記憶功能因為衰減而降低，睡眠可以有效的恢復丟失的記憶。”

Dr Karim Nader, from the Department of Psychology in McGill University in Montreal, said: "Memory research is undergoing a transformation - no longer is memory thought to be a hard-wiring of the brain, instead it seems to be a process of storage and re-storage.
蒙特利爾市麥基爾大學心理學系的卡裡姆·納德博士說：“記憶力研究正在轉型——記憶不再被認為是大腦的硬體，而似乎是一個儲存和再儲存的過程。

"Sleep helps some memories 'mature' and also prunes out unimportant memories."
“睡眠使某些記憶變得‘成熟’，同時也刪掉了那些不重要的記憶。”
