People who enjoy a dream-filled sleep are significantly better at recalling information and making links between facts when they wake, scientists found.
科學(xué)家發(fā)現(xiàn)，那些睡覺時(shí)夢境連連的人們，醒來時(shí)記憶力和關(guān)聯(lián)事物的能力都會(huì)顯著增強(qiáng)。
But recharging with a shallow nap offers no such mental boost, the research suggests.
但同時(shí)該研究顯示，如果僅僅是打個(gè)小盹，不會(huì)對腦力產(chǎn)生如此奇效。
The results of the study add to the growing body of evidence that Rapid Eye Movement (REM) sleep is crucial to the brain’s ability to lay down and consolidate memories.
此前不斷有證據(jù)表明，快速眼動(dòng)睡眠對大腦鞏固記憶的能力至關(guān)重要，而這一研究結(jié)果再次印證了該說法。
An average night’s repose includes four or five spells of REM sleep, but these bursts tend to be lengthier towards the end of the night.
夜間睡眠通常包括四到五個(gè)周期的快速眼動(dòng)睡眠，但直到天亮之前，快速眼動(dòng)睡眠間隔周期呈逐漸延長的趨勢。
This means that adults who get less than the recommended seven to eight hours a night – and therefore insufficient REM sleep – may be damaging their mind’s ability to form strong memories.
這意味著，睡眠時(shí)間不足7-8小時(shí)的成年人形成牢固記憶的能力受到嚴(yán)重影響，因?yàn)樗麄儫o法保障充分的快速眼動(dòng)睡眠時(shí)間。
Although REM sleep is not classified as a type of deep sleep, it is only reached after the brain has passed through deep sleep stages.
盡管快速眼動(dòng)睡眠并不屬于深度睡眠的范疇，但只有在經(jīng)過深度睡眠后，大腦才能進(jìn)入快速眼動(dòng)睡眠狀態(tài)。
For the most recent study, participants were shown groups of three words – such as “cookie”, “heart” and “sixteen” – and asked to find another word that can be associated with all three words.
在最新研究中，研究人員向參與者展示三個(gè)單詞——譬如“cookie（曲奇）”、“heart（愛心）”以及“sixteen(16)”，同時(shí)他們需要找到與這三個(gè)詞語相關(guān)的一個(gè)詞。
In this example, the answer would have been "sweet”. 外語教育￥網(wǎng)www.for68.com
在這個(gè)例子中，正確答案應(yīng)該是“sweet（甜蜜）”這個(gè)詞。
Participants were tested once in the morning and then given the same task again in the afternoon. In between, some were allowed a nap with REM sleep, some a nap without REM sleep, while the others had a quiet rest period.
參與者在早上和下午各進(jìn)行了同樣的測試。而在兩次測試的中間，一些人進(jìn)行了短暫的快速眼動(dòng)睡眠；一些人雖然小睡但并未進(jìn)入快速眼動(dòng)睡眠狀態(tài)；還有一部分人只是安靜地休息了一會(huì)兒。
The quiet rest and non-REM sleep groups showed no improvement in their test results, but the REM sleep proup improved on their morning performance by an average of almost 40 per cent.
對于分別進(jìn)行簡單休息和無快速眼動(dòng)睡眠小憩的兩組參與者，他們實(shí)驗(yàn)結(jié)果并沒有任何進(jìn)步；而進(jìn)入快速眼動(dòng)睡眠的一組測試者，他們早上的測試成績提高了近40%。
Dr Sara Mednick, a sleep researcher at the University of California in San Diego who led the study, believes that the formation of connections between previously unassociated information in the brain – which leads to creative problem-solving – is encouraged by neurological changes which occur during REM sleep.

Scientists have been working on connections between sleep, dreams and brain activity since the REM state was first identified in 1953 by US researchers.
自1953年美國研究人員首次確認(rèn)快速眼動(dòng)睡眠狀態(tài)以來，科學(xué)家一直致力于研究睡眠、夢境以及大腦活動(dòng)三者之間的聯(lián)系。
They found that people woken while their closed eyes made jerking movements recalled much more colourful and elaborate dreams than people woken during other stages of sleep.
他們發(fā)現(xiàn)相對那些從其它睡眠狀態(tài)中醒來的人，從快速眼動(dòng)睡眠狀態(tài)中醒來的人更善于記住那些豐富多彩的夢境。
It is now believed that sleep acts as a sort of mental filing system, enabling the brain to sort relevant information that needs to be retained from useless information which can be discarded. This process take place as memories are shifted from one part of the brain to others.
現(xiàn)在人們堅(jiān)信，睡眠過程就像是一種記憶的歸檔系統(tǒng)。隨著儲存的記憶在大腦中進(jìn)行位置轉(zhuǎn)移，大腦從而對相關(guān)信息進(jìn)行區(qū)分——摒棄無用信息，保留有用信息。
