You probably count on your daily jolt of caffeine to wake up your brain and stay sharp all day long. But downing that coffee, tea, cola, or chocolate bar may be giving you a leg up in another unexpected way: It can improve your proofreading skills, according to a new study.
也許你現(xiàn)在每天要靠咖啡來醒腦、醒神。但其實(shí)咖啡、茶、可樂和巧克力棒還能在其他方面給你意想不到的幫助：一項(xiàng)最新研究表示，它能幫你提高你的校正能力。

In the study, published in the Journal of Experimental Psychology: Applied, researchers asked 36 college students who consumed low levels of caffeine -- about a half-cup of coffee a day -- to do a "language task." The students were given 5 minutes to read a one-page news story, and needed to identify and correct as many spelling and grammatical mistakes as they found in that time.
在《實(shí)驗(yàn)心理學(xué)期刊》上發(fā)表的文章：研究者讓36名對(duì)咖啡攝入程度較低的大學(xué)生——每天咖啡攝入量低于半杯——做一個(gè)“語(yǔ)言測(cè)試”。給這些受測(cè)試者5分鐘時(shí)間來讀一篇長(zhǎng)度約為一頁(yè)的文章，讓他們找出并更正文內(nèi)的拼寫和語(yǔ)法錯(cuò)誤。

Forty-five minutes before taking the proofreading test, students were randomly given a capsule containing one of four doses of caffeine: none, 100 milligrams, 200 milligrams , or 400 milligrams.
在校對(duì)測(cè)驗(yàn)開始前45分鐘，有四種劑量的咖啡因膠囊，分別是不含咖啡因、100毫克、200毫克、和400毫克，這些膠囊讓參加測(cè)驗(yàn)的學(xué)生任意領(lǐng)取一枚。

In a second study, researchers repeated the same experiment with 38 college students who consumed higher levels of caffeine each day. The java junkies typically had at least 300 milligrams of caffeine daily.
在第二個(gè)試驗(yàn)中，研究人員還是以同樣的方法對(duì)38名每天會(huì)攝入高劑量咖啡因的學(xué)生做了測(cè)試。這些咖啡控們每天至少攝入300毫克咖啡因。

The low-caffeine crowd was best at finding and correcting these grammatical goofs at 200 milligrams of caffeine. But it took more in the highly caffeinated -- 400 milligrams -- to achieve the highest detection rates.
不太喝咖啡的那一組學(xué)生在喝入200毫克咖啡因后找到和更正語(yǔ)法錯(cuò)誤的能力最佳，而攝入400毫克咖啡因時(shí)，他們找出文中錯(cuò)誤的檢測(cè)能力是最強(qiáng)的。

Interestingly, caffeine didn't affect the students' skill at finding and correcting misspelled words. And it had no effect on noticing mistakes in words that sound alike, such as weather and whether or seams and seems.
有趣的是，咖啡因并沒有對(duì)學(xué)生們找到和更正拼錯(cuò)單詞的能力造成影響。對(duì)于發(fā)現(xiàn)weather和whether、seams和seems這樣發(fā)音類似的詞也無影響。

"Individuals who habitually consume caffeine on a daily basis are less likely to benefit from caffeine's performance advantages without upping the dose," Brunye says.
“而平時(shí)習(xí)慣每天喝咖啡的人除非加大劑量，否則獲益無多?！盉runye說。
