[雙語(yǔ)新聞] 研究表明:記住的東西太多反而影響記憶力

 

Scientists say the problem is that you know too much - and you need to declutter, or spring-clean your mind.
科學(xué)家稱記不住東西是因?yàn)槟阌涀√鄸|西。你需要對(duì)你的大腦進(jìn)行一次大掃除，刪除多余的記憶。

Experiments show that the memory lapses that come with age are not simply due to brain slowing down. Instead, they can be blamed on the well-used brain finding it more and more difficult to stop irrelevant information interfering with the task in hand.
實(shí)驗(yàn)顯示，年紀(jì)大的人記憶力差并不是因?yàn)槟X子不夠用，恰恰相反，正是因?yàn)樗麄冾^腦運(yùn)轉(zhuǎn)靈活，處理手頭工作時(shí)，不相干的記憶會(huì)不停地冒出來(lái)干擾他們。

The first step in the study was to compare the working memory of the young and old.In the context of the study, it involved giving the volunteers groups of sentences and asking them to work out whether each line made sense - and to remember the last word of each sentence.Overall, the younger people, who had an average age of 23, did better.
第一項(xiàng)實(shí)驗(yàn)是對(duì)比年輕人和老年人的短期記憶能力。具體的試驗(yàn)內(nèi)容包括給實(shí)驗(yàn)對(duì)象一組句子，讓他們判斷這些句子是否有意義，并且記住每句話的最后一個(gè)單詞。
結(jié)果顯示平均年齡為23歲的年輕實(shí)驗(yàn)對(duì)象做的更好。

Researchers then did a second experiment to see what was hindering the older volunteers, who had an average age of 67. This involved being shown  pictures of eight animals and being asked to memorize the order in which the creatures appeared.
研究人員進(jìn)行了第二項(xiàng)實(shí)驗(yàn)，目的在于找到影響這群平均年齡為67歲的老年實(shí)驗(yàn)對(duì)象的原因。實(shí)驗(yàn)內(nèi)容包括給他們看八幅動(dòng)物圖片，并記住圖片出現(xiàn)的先后次序。

The volunteers were then shown dozens of the pictures and asked to click on their computer mouse when the first animal in their memorized sequence occurred, then the second and so on. The older adults found it more difficult to progress, suggesting the previous picture was stuck in their mind.
實(shí)驗(yàn)結(jié)束后，研究人員要求這些老年人根據(jù)自己的記憶在電腦屏幕上按圖片出現(xiàn)順序點(diǎn)擊動(dòng)物圖片。這些老年人表示這個(gè)實(shí)驗(yàn)很難，因?yàn)樯弦环鶊D片在他們腦子里揮之不去。

Mervin Blair, of Montreal's Concordia University, said: "We found that the older adults had more difficulty in getting rid of previous information, which accounted for a lot of the working memory problems seen in the study."
蒙特利爾肯考迪亞大學(xué)的馬文•布萊爾說(shuō)：“我們發(fā)現(xiàn)老年人不太容易忘掉過(guò)去的事情，正是這個(gè)原因?qū)е铝硕唐谟洃浾系K。”

A third study confirmed that the memory problems were not simply due to a simple slowing down of the mind.
第三項(xiàng)實(shí)驗(yàn)證明記不住東西并不是因?yàn)樗季S速度減緩。

Mr Blair says that the older mind appears to have trouble suppressing irrelevant information. This makes it more difficult to concentrate on the here and now. For those who have trouble remembering, he suggests relaxation exercises to declutter the mind.
布萊爾稱老年人似乎很難摒除無(wú)關(guān)信息，這讓他們很難集中精力處理眼前的工作。他建議那些記不住東西的人放松身心，忘掉那些不重要的事情。

"Reduce clutter, if you don't, you may not get anything done."
他說(shuō)道：“忘掉不重要的記憶，才能做好當(dāng)前的事情。”
