The volunteers then had to identify when the spoken letter or the square's position matched that of several screens earlier.

志愿者必須在聽到的字母或者藍(lán)框位置與之前屏幕出現(xiàn)的相符時(shí)作出判斷。

The more they practiced and honed their short-term memory, the greater the improvement in the purest form of brain power, fluid intelligence—the ability to reason and solve problems independently of existing knowledge. The same results have also been achieved in school-age kids.

他們短期記憶力的訓(xùn)練強(qiáng)度越大，腦力最直接的表現(xiàn)形式——流體智力的改善越大。流體智力是根據(jù)已有知識(shí)獨(dú)立理清問題、解決問題的能力。該實(shí)驗(yàn)結(jié)果也在學(xué)齡兒童身上得到了證實(shí)。

The other brain element you can train in order to raise your IQ is attention. Neuroscientists have shown over and over that attention is the requisite condition of learning and thus of boosting intelligence.

另一個(gè)提高IQ的辦法就是鍛煉你的注意力。神經(jīng)學(xué)家一次次證明注意力是學(xué)習(xí)能力的必要條件，因而也有助于提高智力。

While improving your brain takes work, the good news is there are some accessible ways to go about it. Aerobic exercise, for one, is very good for both the brain and muscles.

雖然提高智力是一項(xiàng)龐大工程，但幸運(yùn)的是我們還是有路可走的。比如，有氧運(yùn)動(dòng)就是既提高腦力又鍛煉肌肉的好辦法。

Walking 30 minutes a day five times a week stimulates production of a molecule that nurtures the creation of the new neurons and synapses that underlie learning.

每天步行30分鐘，一周五次，可以促進(jìn)一些分子的分泌，這種分子能促進(jìn)神經(jīng)元和突觸的生成，而學(xué)習(xí)能力的產(chǎn)生正是源于這些神經(jīng)元和突觸。

Scientists have also found that exercise increases gray matter in the region of the brain that processes new knowledge and sends it to be stored permanently in the frontal cortex, helping one become more knowledgeable.

科學(xué)家們還發(fā)現(xiàn)，鍛煉身體可以增加腦部某個(gè)區(qū)域的灰質(zhì)，該區(qū)域主要負(fù)責(zé)處理大腦接收的新知識(shí)，將其傳遞給額皮質(zhì)永久儲(chǔ)存，增加人的知識(shí)儲(chǔ)備。

A midday nap not only can restore brain power to its fully awake best but can also raise it beyond what it would have been without some shut-eye.

午睡不僅可以最大程度上將腦力恢復(fù)到完全清醒狀態(tài)，同時(shí)還可以使腦力在原沒有睡眠的基礎(chǔ)上有所提高。

Too excited to nap during the day? Then drink some coffee. Caffeine can make your mind sharper. Learning a second language can also help.

白天時(shí)過于興奮而無(wú)法入睡？那就喝點(diǎn)咖啡吧。咖啡因是可以讓你的思維更加敏捷。另外，學(xué)習(xí)外語(yǔ)也可以幫助提升腦力。
