Napping after learning something new could help you commit it to memory - as long as you dream, scientists say.

科學(xué)家稱，在學(xué)了一些新東西之后小睡一會(huì)兒能夠幫助大腦記憶-只要你做了夢(mèng)。

They found people who dream about a new task perform it better on waking than those who do not sleep or do not dream.

他們發(fā)現(xiàn)一些做夢(mèng)夢(mèng)到一項(xiàng)新任務(wù)的人醒來(lái)之后會(huì)很好地完成這項(xiàng)任務(wù)，而且比那些不睡覺或不做夢(mèng)的人完成地要好一些。

Volunteers were asked to learn the layout of a 3D computer maze so they could find their way within the virtual space several hours later.

自愿參與這項(xiàng)實(shí)驗(yàn)的人被要求了解一個(gè)3D電腦迷宮的構(gòu)成，只有了解了那個(gè)之后，幾個(gè)小時(shí)之后，他們才可能從虛擬的空間中走出來(lái)。

Those allowed to take a nap and who also remembered dreaming of the task, found their way to a landmark quicker.

這些允許小睡也記住要夢(mèng)到任務(wù)的人，很快就找到了一個(gè)地標(biāo)。

The researchers think the dreams are a sign that unconscious parts of the brain are working hard to process information about the task.

研究者們發(fā)現(xiàn)，做夢(mèng)是大腦的下意識(shí)部分正在認(rèn)真處理有關(guān)這項(xiàng)任務(wù)的信息的信號(hào)。

Dr Robert Stickgold of Harvard Medical School, one of the authors of the paper, said dreams may be a marker that the brain is working on the same problem at many levels.

來(lái)自哈佛大學(xué)醫(yī)療學(xué)院的羅伯特?斯第高特博士（Dr Robert Stickgold ），同時(shí)也是此次研究報(bào)告的作者之一，表示，做夢(mèng)可能是大腦在不同程度地處理著同一個(gè)問題。

He said: "The dreams might reflect the brain's attempt to find associations for the memories that could make them more useful in the future."

他說(shuō)道，“你做的夢(mèng)可能反映出，大腦正嘗試著找與你的記憶相關(guān)聯(lián)的東西，以此來(lái)使他們?cè)趯?lái)變得更加地有用處?！?/div>

Study tips

學(xué)習(xí)建議

Co-author Dr Erin Wamsley said the study suggests our non-conscious brain works on the things that it deems are most important.

另一位研究人員伊爾琳?渥姆斯里博士（Dr Erin Wamsley）稱，根據(jù)這份報(bào)告，人類大腦中的下意識(shí)部分會(huì)在它認(rèn)為最重要的的事情上下功夫。

"Every day we are gathering and encountering tremendous amounts of information and new experiences," she said.

“每天我們都在收集大量的信息也會(huì)遇到各種各樣的新情況 ?！彼f(shuō)道。

"It would seem that our dreams are asking the question, 'How do I use this information to inform my life?"

“看起來(lái)，好像你的大腦在夢(mèng)中問道‘我應(yīng)該怎樣利用這些信息來(lái)指導(dǎo)我的生活呢？’”

The research, published in the academic journal Cell Biology, could have practical implications.

這份刊登在學(xué)術(shù)期刊《細(xì)胞生物學(xué)》上的報(bào)告可能會(huì)產(chǎn)生實(shí)際的效用。

The scientists say there may be ways to take advantage of this phenomenon for improving learning and memory.

科學(xué)家稱，有很多方法可以利用這種現(xiàn)象，來(lái)提高學(xué)習(xí)能力和記憶力。

For example, students might be better studying hard before bedtime, or taking a nap after a period of afternoon study.

例如，學(xué)生在睡前努力學(xué)習(xí)，或者一段時(shí)間的午間學(xué)習(xí)之后睡一會(huì)，學(xué)習(xí)效果會(huì)更佳。
