Researchers have found that peoples' mental abilities peak at 22 before beginning to deteriorate just five years later.

研究人員發(fā)現(xiàn),人的智力在22歲時(shí)達(dá)到頂峰,而僅在五年之后就會(huì)開(kāi)始衰退。

Professor Timothy Salthouse said the results suggested that therapies designed to prevent or reverse age-related conditions may need to start earlier, long before people become pensioners.

蒂莫西 索爾特豪斯教授稱(chēng),研究結(jié)果表明,旨在預(yù)防或扭轉(zhuǎn)與年齡有關(guān)的癥狀的治療應(yīng)盡早開(kāi)始,而非等到退休。

Almost half of over 50s 'unaware of leading cause of blindness'" Results converge on a conclusion that some aspects of age-related cognitive decline begin in healthy, educated adults when they are in their 20s and 30s," he said.

在50歲以上的人中,有近一半的人“不清楚導(dǎo)致智力衰退的主要原因”。蒂莫西稱(chēng),研究發(fā)現(xiàn),對(duì)于身體健康,受過(guò)教育的成年人來(lái)說(shuō),與年齡有關(guān)的一些認(rèn)知衰退癥狀在二三十歲時(shí)就開(kāi)始了。

The study of 2,000 men and women lasted over seven years. The respondents, aged between 18-60, were asked to solve visual puzzles, recall words and story details and spot patterns in letters and symbols.

該研究持續(xù)七年之久,共對(duì)兩千名18歲至60歲之間的男性和女性進(jìn)行了調(diào)查。研究人員要求調(diào)查對(duì)象做圖形猜謎,復(fù)述單詞和故事細(xì)節(jié),以及指認(rèn)字母和符號(hào)類(lèi)型等各項(xiàng)測(cè)試

Similar tests are often used to diagnose mental disabilities and declines, including dementia.

類(lèi)似的測(cè)試常被用于診斷智力殘疾和包括癡呆癥在內(nèi)的智力衰退等。

The research by the University of Virginia found that in nine out of 12 tests the average age at which the top performance was achieved was 22.

弗吉尼亞大學(xué)開(kāi)展的這項(xiàng)研究發(fā)現(xiàn),在總共12項(xiàng)測(cè)試中,其中有9項(xiàng)獲得最高分的調(diào)查對(duì)象平均年齡是22歲。

The first age at which performance was significantly lower than the peak scores was 27 – for three tests of reasoning, speed of thought and spatial visualisation. Memory was shown to decline from the average age of 37. In the other tests, poorer results were shown by the age of 42.

從邏輯推理、反應(yīng)速度和空間想象力三項(xiàng)測(cè)試的結(jié)果來(lái)看,調(diào)查對(duì)象的得分首次明顯低于之前的最高水平是在27歲。記憶力開(kāi)始衰退的平均年齡是37歲。在其它幾項(xiàng)測(cè)試中,調(diào)查對(duì)象的得分在42歲時(shí)開(kāi)始降低。

However, the report published in the academic journal Neurobiology Of Ageing, found that abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until at the age of 60.

但發(fā)表于《衰老神經(jīng)生物學(xué)》學(xué)術(shù)期刊上的這項(xiàng)研究報(bào)告表明,從詞匯或常識(shí)測(cè)試的結(jié)果看,基于知識(shí)積累的能力到了60歲會(huì)開(kāi)始增長(zhǎng)。

Twenty-seven has long had negative connotations, as it is the age at which many popular musicians died, including Jimi Hendrix, Jim Morrison, Brian Jones, Janis Joplin and Kurt Cobain.

27歲一直是個(gè)不太吉利的年齡,很多流行歌手在27歲時(shí)去世,其中包括吉米 亨德里克斯、吉姆 莫里森、布賴(lài)恩 瓊斯、賈尼斯 喬普林和柯特 科本。
