Oh sorry Rob, you caught me napping. It's that time of day when I need to nod off – or in other words, fall asleep.
噢,對不起,Rob。被你抓到我在打盹了。白天的時候我需要打一會盹——或者換句話說就是睡覺。
Well, sleeping on the job – or sleeping at work - is no bad thing – and I hope today's programme will wake you up to the idea that sleeping in the workplace might be a good thing.

Long-distance runners may at times worry about their heart health while pounding out the miles. But a study finds that heat stroke fells many more runners than does a bum ticker.
長跑運動員在連續跑了數英里之後,有時可能會擔心自己的心臟健康。但是一項研究發現相對於心臟不好,中暑能擊倒更多的奔跑者。
Heat stroke can damage a person's brain, heart, kidneys and muscles. And new data underscores the toll it takes.
中暑能傷害一個人的大腦,心臟,腎臟,和肌肉。而且少量數據還強調了中暑的巨大代價。
Researchers examined health records from more than 130,000 runners who competed in events in Tel Aviv during a seven-year span. The analysis revealed that distance runners were 10 times more likely to experience heat stroke than serious cardiac problems. You can find more 60-Second Health on chinavoa.com.
研究人員檢查了7年中在特拉維夫市參加比賽的13萬多運動員的健康檔案。分析表明,長跑運動員中暑的機率要比患嚴重心臟病機率的多10倍。
All the fatal or life-threatening events were from heat stroke. The study is in the Journal of the American College of Cardiology. [Lior Yankelson et al,Life-Threatening Events During Endurance Sports: Is Heat Stroke More Prevalent Than Arrhythmic Death?]
所有致命和危及生命的事件都來自中暑。這項研究被發表在《美國心臟病學會》雜誌上。

Everybody eats. And consumers increasingly try to consider the environmental effects of their food choices. For example, if you want to eat meat, how do your choices compare? That's what a group of researchers set out to discover.
每個人都要吃飯。而越來越多的消費者在選擇食物時,試著去考慮其中的環境影響。例如,如果你想要吃肉,你怎樣去比較去選擇呢?這就是一組研究人員打算著手研究的問題。
And they found that raising one animal is dramatically more environmentally draining than all the others: cows. The research is in the Proceedings of the National Academy of Sciences. [Gidon Eshel et al.,Land, irrigation water, greenhouse gas, and reactive nitrogen burdens of meat, eggs, and dairy production in the United States]
而且他們發現飼養牛這種牲畜,要比飼養其他動物,產生更多的環保排水問題。這項研究被發表在《美國國家科學院院刊》上。
The scientists noted the challenge in accessing data and creating metrics that can be compared across livestock and to potato, wheat and rice production.
科學家指出了在訪問數據和創建指標上面臨的挑戰,該指標可以用於將飼養牲畜與種植土豆、小麥、和大米進行比較分析。
They settled on national data from the U.S. Departments of Agriculture, the Interior and Energy. The team calculated the production costs by assessing land area, water needs and fertilizer. They also analyzed greenhouse gas emissions.
美國農業部,內政部和能源部授予了他們查閱國家數據的權利。該研究團隊,通過評估土地面積、對水的需求量和肥料用量,來計算生產成本。他們還分析了溫室氣體的排放。
Producing pork, poultry, eggs and dairy were between two and six times less efficient than growing potatoes, wheat and rice. And in the current agricultural system, beef uses 28 times more land, 11 times more water and 6 times more fertilizer than the average of the other categories of livestock. Cattle ranching also creates five times more greenhouse gas emissions. You can find more 60-Second Science on chinavoa.com.

IImagine paradise. Now imagine the Bahamas. Hard to tell the difference. The island nation boasts brilliant white sands, clear waters and vibrant coral reefs.
這裡是想像的天堂。現在想像一下巴哈馬群島。你很難講出它的獨特之處。這個島國擁有亮白的沙灘,清澈的海水和充滿生氣的珊瑚礁。
The waters of the Bahamas are so clear because they're low in nutrients. They're therefore relatively free of the microscopic life that turns richer waters murky—and is normally associated with the deposition of calcium carbonate. So how did the reefs come to be?
巴哈馬的海水是如此清澈是因為營養鹽含量低。因此它們相對的擺脫了微生物的影響,這些微生物可以使得營養較豐富的海水變得朦朧,這通常和碳酸鈣沉澱物有關。所以礁石是怎樣形成的呢?
A group of scientists argue that dust from across the Atlantic in Africa may have initiated the process.
一組科學家認為可能是非洲的灰塵橫跨大西洋來到這裡,從而開始了這一進程。
Dust blows off the Sahara today, reaching all the way to the Americas. Fertilized by the dust, cyanobacteria can then grow and pull carbon dioxide out of the water. That activity in turn causes calcium carbonate to precipitate, an event known as a whiting. And the cyanobacteria also fix nitrogen from the atmosphere, helping other microorganisms to thrive. You can find more 60-Second Earth on chinavoa.com.
灰塵從現在的撒哈拉沙漠被吹起來,一直到達了美洲。藍藻細菌經過這些灰塵的受精,就可以生長,並把水中的二氧化碳排放出水面。這個過程反過來也了導致碳酸鈣沉澱的形成,該過程又叫做whiting反應。而且藍藻細菌也可以調整空氣中的氮含量,幫助其他微生物茁壯成長。
This may have been going on for a very long time. Enough of such cyanobacterial work over enough time and eventually you get the Bahamas, built out of calcium carbonate. At least that's what's suggested by trace elements in Bahama sediments. The hypothesis is in the journal Geology. [P. K. Swart et al, The fertilization of the Bahamas by Saharan dust: A trigger for carbonate precipitation?]
這個過程可能需要很長一段時間,需要足夠多的這種藍藻細菌,在足夠多的時間裡共同努力,最終才會得到這個用碳酸鈣建造起來的巴哈馬群島。至少這是通過查探巴哈馬群島的沉澱物之後而提出的。該假設被發表在《地質學》雜誌上。

If you've seen Google's promotions for its Internet-connected Glass headset, you already know the technology will be great for showing off your rad mountain biking skills and skydiving exploits. The less daring among us will be relieved to know that medical workers are also interested in the technology—to improve patient care.
如果你曾經聽過谷歌所推出的頭戴式聯網眼鏡,那麼你就已經知道了,這個設備將會非常有利於你炫耀你騎山地車的車技和空中跳傘的壯舉。當知道醫護人員對這項科技感興趣是為了改善對病人的護理,我們中這些膽子不太大的人才如釋重負。
MedEx Ambulance Service in Skokie, Ill., bought two pairs of Glass to test as a video consultation tool with ER doctors at a hospital they serve, according to the Chicago Tribune. The paramedics want to be able to get input from doctors about treatment options while patients are still en route.
根據《芝加哥論壇報》,斯科奇MedEx的救護車服務機構,購買了兩副谷歌眼鏡作為醫院急診室醫生視頻會診的工具來檢測其功效。醫護人員希望當病人還在運送途中時,可以通過此設備來徵求醫院醫生的治療方案。
Earlier this year Rhode Island Hospital began studying Glass as a low-cost way to connect emergency room patients with an off-site dermatologist for a live consultation when needed. You can find more 60-Second Tech on chinavoa.com.
今年早些時候,羅德島醫院就開始以低成本的方法,連通急診室患者和醫院外的皮膚科醫生進行了一個他們所需要的現場諮詢,這樣來研究該谷歌眼鏡,。
All well and good. But the Food and Drug Administration needs to give its blessing before Glass can be widely used in medical settings. Privacy is the big sticking point.
好倒是好,但是美國的食品和藥物管理局表示,在該眼鏡被廣泛的應用於醫療環境之前,只是給予祝福,因為隱私會成為其中最大的阻塞點。
Still, score one for Google Glass, which has already been banned from more places than Charlie Sheen, most recently at Comic Con during film screenings. Now there's an idea: a live Google Glass feed from Charlie Sheen.

Not all solar energy capture devices make electricity directly. For example, steam generated from solar energy can turn turbines, which then produce electricity. And, in what could be especially useful in remote regions, solar steam can desalinate water and be used in sanitation and equipment sterilization.
並不是所有的太陽能吸收裝置都可以直接將太陽能轉換成電能。例如,太陽能所產生的水蒸氣可以轉動渦輪,這樣就可以產生電能。而且,這在偏遠地區可能非常有用,太陽能水蒸氣可以淡化海水,還可以對環境衛生設備進行消毒。
Now a new technique looks to be the most efficient way yet created to use solar energy to generate steam.
現在有一種新技術看起來是目前利用太陽能來產生水蒸氣的最有效方法。
To absorb sunlight, M.I.T. researchers created a porous disc of graphite flakes. Underneath the disk is a layer of insulating carbon foam that floats on water. The foam prevents heat from being lost to the water, and has a tangle of interconnected small pores. You can find more 60-Second Science on chinavoa.com.
為了吸收陽光,麻省理工學院的研究人員製造了一個多孔滲水的石墨薄片圓盤。圓盤下面有一層絕緣的泡沫碳漂浮在水面上。泡沫可以防止熱量流失到水中,也可避免這些互通的小氣孔處於混亂狀態。
As sun heats the graphite, it creates a pressure difference that pulls water up through the foam pores, like a sponge. When the water hits the graphite hot spot, it turns into steam.
隨著太陽不斷的加熱石墨,就會產生一個壓力差,這樣就可以像擠海綿一樣,把水從泡沫孔隙中擠壓出來。當水落在石墨的加熱點上就會轉化成水蒸氣。
The scientists report that this inexpensive system reaches 85 percent efficiency in converting the solar energy into steam. The study is in the journal Nature Communications. [Hadi Ghasemi et al, Solar steam generation by heat localization]

These days the worst urban decay is found not in big cities but in small ones
當下,小城市而非大城市的都市衰敗現象最為嚴重
WHEN recession hit Hartlepool in 2008 it hit hard, says Billy Reid, the owner of a local key-cutting and engraving business. His stall in the shopping centre—an ugly grey 1970s box that dominates the centre of the town—sits between gaps where other firms have disappeared. 「We lost the Woolworths, we lost Superdrug. I've got two staff and just this year for the first time I've had to cut their hours,」 he says. Nobody is moving house and nobody has much money—so few people need keys cut or gifts engraved.
2008年的金融危機對哈特爾浦造成了嚴重的影響,Billy Reid,當地一個鑰匙配製和鐫刻店的老闆說,他經營的攤位是個20世紀80年代的小房間,灰色牆壁,實在不怎麼好看,不過那時市中心的房子大抵都是這樣的。當時,周圍別的商店都已關門停業「伍爾沃斯關門了,超級藥房也關門了,我有兩個員工,今年我不得不開始減少他們的工作時間」他說,沒人在搬家,也沒人錢多,所以很少有人需要配鑰匙或給禮物鐫刻。

Britain's economy is finally crawling out of recession. On October 8th the IMF sharply upgraded its growth forecast for 2013. But the recovery is far from evenly spread. In London and the south-east, house prices and employment are soaring. In places such as Hartlepool, a former shipbuilding and steel town in Teesside, on the north-east coast of England, there is precious little sign of improvement. The local unemployment rate is almost twice the national average, at 13%. Last year there was nobody in work in 30% of the town's working-age households.

英國經濟終於慢慢的走出衰退,10月8日,國際貨幣基金組織大大的提高了2013年經濟預期,但是經濟復甦還遠沒有穩健均勻的展開,在倫敦和英國東南部, 房價和就業都在迅猛飆升,在類似於哈特爾浦(位於英國東北海岸的提賽德的一個昔日造船和產鋼的城鎮)的地方,幾乎沒有復甦的跡象。當地失業率高達13%,幾乎是全國水平的兩倍。去年該城鎮30%的適齡工作家庭成員都出於失業狀態。
Partly, this reflects the extraordinary success of London and continuing deindustrialisation in the north of England. Areas such as Teesside have been struggling, on and off, since the first world war. But whereas over the past two decades England's big cities have developed strong service-sector economies, its smaller industrial towns have continued their relative decline. Hartlepool is typical of Britain's rust belt in that it has grown far more slowly than the region it is in. So too is Wolverhampton, a small city west of Birmingham, and Hull, a city in east Yorkshire.
在某種程度上,這反映了倫敦非比尋常的成功和英國北部的不斷擴延的逆城市化現象,像提賽德的區域自一戰以來就經常處在掙扎邊緣, 然而,在過去20年間,強大的服務業經濟在英國大城市蒸蒸日上,而在小城市卻江河日下。。哈特爾浦 就是典型的一個拖後退的城鎮,它比他所在的區域發展速度慢的多, 同樣的還有沃爾夫漢普頓, 伯明翰西部的一個小城市;赫爾,約克郡東部的一個城市。
In Hartlepool, 28% of shops are empty, according to the Local Data Company, a private research firm. Chain stores, widely blamed for destroying high streets in richer bits of Britain, are mostly absent. In nearby Middlesbrough, whole streets of terraced houses are boarded up—the legacy of a failed plan to renew the market by knocking down old houses and building new ones. In Hull, teenagers in baseball caps and tracksuits wander aimlessly.
據一傢俬營調查研究公司「當地數據公司」統計,在哈特爾浦, 28%的商戶都關門了,廣受詬病其佔領了倫敦富有區域高檔街區的連鎖商店也大多被空置了,在附近的Middleborough, 整條街聯立的房子都被空置,這是曾經計畫拆除舊房改建新房以復興市場的計畫失敗的產物。而在Hull, 帶著棒球帽穿著運動杉的青少年到處漫無目的的遊蕩。

Wanna know what the most popular movies, albums and video games are? Ask the internet. But don't Google it. Check what other people Googled. That's the theory behind Google Flu Trends—which crunches search data to forecast flu prevalence. With admittedly mixed results.
如果你想知道現在最受歡迎的電影,唱片和電子遊戲是什麼,問互聯網就可以知道了,但是不要用谷歌搜索。檢查其他人搜索了什麼,這就是谷歌流感趨勢背後所運用的理論——通過處理搜索數據來預測流感的流行。無可否認,結果應該是好壞參半的。
Nevertheless, researchers have applied the idea to the stock market. They found that when searches related to business and politics go up, the market tends to take a dive. Queries for words like "election," "senate," and "CEO" are predictive of the downward trend—but not terms like "church," "earthquake" and "geometry."
然而,研究人員將這一觀點運用到股票市場,他們發現,當與商業和政治相關的搜索增多時,市場就有暴跌的傾向。搜索查詢「選舉」、「參議員」和「首席執行官」這類詞彙時,就會預示著市場會有下跌的趨勢,而「教堂」、「地震」和「幾何學」等則不會產生這樣的效果。
Why the correlation? The researchers say investors and the public may be more likely to search for information on business and government when they're concerned about the economy. And if confidence in the economy drops, so might stock prices. The findings appear in the Proceedings of the National Academy of Sciences. [Chester Curme et al, Quantifying the semantics of search behavior before stock market moves]
為什麼它們之間會產生關聯呢?研究人員稱,可能當投資者和大眾擔憂經濟狀況時,他們更傾向於搜索關於商業和政府的相關信息。而且如果他們對經濟的信心下降,可能股票的價格也會下降。該研究被發表在《美國國家科學院院刊》上。
Over time, the correlation weakened—a sign that traders may already be using Internet search data in automated trading algorithms.
隨著時間的推移,這種聯繫會變弱哦——一種跡象表明,交易員可能已經將網絡搜索數據用於進行自動交易運算。
"Generally speaking, if an opportunity like this is known, then the effect will diminish, and that's what we think we're seeing in the data we looked at, from 2004 to 2012." Lead author Chester Curme, a research fellow at the Warwick Business School.
首席作者切斯特‧柯姆,是華威商學院的一名研究人員。他說:「一般來講,如果我們已經知道有這種可能性(機會),那麼它所產生的這種效果就會減弱。這就是為什麼我們認為要著眼於我們在2004—2012年這些數據中我們所能發現的東西。」

Such streaks are all easily within the bounds of statistical probability. But when they're happening, people believe that they have what is often called the hot hand. Our brains are hardwired to find such patterns and meaning. And now researchers find that other primates also appear to believe in streaks.
在統計概率範圍內,這種連續事件是很容易做到。但是當它們發生時,人們總會認為是因為所謂的熱手效應。我們的大腦會習慣性的去尋找這樣的模式和意義。而現在,研究人員發現其他靈長類動物似乎也相信這種連續事件。

But in the random game, the monkeys made moves indicating that they nevertheless expected patterns to occur. The study is in the Journal of Experimental Psychology: Animal Learning and Cognition.

哇,聽著好饞。不過,肉食者,比如咱倆,其實應該節制吃肉的總量了。
That's right because in the programme today we're discussing how eating meat can add to the problem of greenhouse gas.
今天的節目,就是關於吃肉與溫室氣體增加關係的討論。

Diabetics who live in poor areas in California are far more likely to suffer an amputation than are diabetics in wealthier neighborhoods. So finds an analysis in the journal Health Affairs. [Carl D. Stevens et al, Geographic Clustering Of Diabetic Lower-Extremity Amputations In Low-Income Regions Of California]
在加州貧困地區居住的糖尿病患者比居住在富裕地區的患者更容易遭受截肢。我們在《健康雜誌》上發現了關於這一現象的一篇分析文章。
The study reveals that patients in low-income zip codes were up to 10 times more likely to lose a leg or foot than diabetic patients in more affluent zip codes. In poor areas like Compton, as many as 10.7 out of 1,000 diabetic adults ages 45 and older wound up losing a lower limb due to diabetes complications. In wealthier areas, including Malibu and Beverly Hills, no more than 1.5 diabetics per 1,000 lost a limb to the disease.
研究表明,低收入地區的糖尿病病人失去一條腿或腳的概率是富裕地區的10倍。在像康普頓這樣的貧困地區,1000位年齡在45歲以上的糖尿病患者中,由於糖尿病併發症而失去一條腿的多達10.7個。而在包括馬里布和貝弗利山在內的富裕地區,1000名糖尿病患者中失去一條腿的卻不超過1.5個。
Fewer healthcare options for poorer patients and their providers may have contributed to the disparity, the researchers write.
研究人員寫道,貧窮病人較少的醫療保健選擇和為他們進行醫療保健的醫護人員,可能是造成這一差別的原因。
The diabetes patients most at risk for amputations were male, older than 65, black and non-English speaking.
糖尿病患者最有截肢危險的是,65歲以上的不講英語黑人男性。
When blood sugar and other health metrics are carefully monitored and controlled, diabetes amputations are much more preventable. Otherwise, diabetes can lead to impaired circulation in the feet and nerve damage. Those conditions, in turn, can keep patients from noticing developing infections.

How often have you longed to have time to just sit quietly and think? Well, be careful what you wish for. Because a study shows that many people find such interludes incredibly unpleasant. So uncomfortable, in fact, that they would rather zap themselves with electricity than be left alone with their thoughts. The shocking results appear in the journal Science. [Timothy D. Wilson et al, Just think: The challenges of the disengaged mind]
你經常渴望可以有時間靜靜的坐著想事情嗎?那樣的話,你得小心你會有這樣的盼望了。因為一項研究表明,很多人發現這樣靜靜的思考間歇時間段讓人感覺非常的不愉快。實際上,讓人感覺很不舒服,他們寧願用電流電擊自己,也不願意獨自在那思考。這令人震驚的研究結果被發表在《科學》雜誌上。
In the experiment, participants were asked to sit alone in a room for up to 15 minutes…with no cell phone, no reading material, no music—so, nothing to entertain them, save their own rambling thoughts. Afterward, most subjects reported that they found it difficult to concentrate and that they did not enjoy the experience. You can find more 60-Second Science on chinavoa.com.
在該研究的試驗中,參與者被要求單獨坐在一個房間15分鐘……沒有手機,沒有任何閱讀材料,也沒有音樂——除了他們自己散漫的思想,沒有其他什麼東西可以拿來消遣時間。後來,大多數的受試者報告稱,他們發現自己很難集中注意力,而且他們並不享受這樣的獨處經歷。
Then, to assess just how much subjects disliked doing nothing, the researchers repeated the experiment. Only this time they gave volunteers the added option of occasionally giving themselves a mild electric jolt. Two thirds of the men in the study—and one quarter of the women—chose to take advantage of the shock option at least once during their time out.
然後,僅僅為了評估多少人不喜歡在那呆著什麼都不做,研究人員又再一次進行了該試驗。只是在這次的試驗中,研究人員給了志願者們額外的選擇,偶爾會給他們一個輕微的震顫電擊。該研究中,在這段試驗時間裡,三分之二的男性和四分之一的女性至少選擇利用過一次電擊。
The results suggest that if there’s anything worse than losing your mind, it’s getting caught alone with it.
—Karen Hopkin
研究結果表明,如果有什麼比讓你失去思想理智更難以承受,那就是獨自陷於自己的思想理智之中。—凱倫·霍普金

Searches for extraterrestrial intelligence have focused on various signs of life. And one signature of alien intelligence may be, cough, cough, air pollution.
尋找外星人要專注於各種生命的跡象,而且外星人的一個鮮明標誌可能是,他們因為大氣污染而產生的咳嗽。
NASA's James Webb Space Telescope, due to launch in 2018, should be powerful enough to detect chlorofluorocarbons, CFCs. These ozone-destroying chemicals are used in aerosol sprays on Earth. Maybe another planet's denizens also employ them. You can find more 60-Second Space on chinavoa.com.
美國宇航局的詹姆斯韋伯太空望遠鏡降於2018年發射,應該強大到能夠檢測含氯氟烴(CFCs)。這些破壞臭氧層的化學物質在地球上被用做噴霧劑。也許另一個星球的居民也使用它們。
A new analysis of this idea notes that aliens would have to be heavy users. The Webb scope could only detect the chemicals if they were 10 times more prevalent than here on Earth. And even then, the planet would have to orbit a special kind of star, a white dwarf, for the CFCs to show up. White dwarfs—the ultimate destiny of stars like the sun—maximize the pollution signal.
關於這種想法的一項新的研究指出,外星人會是這種化學物質的重度使用者。如果他們對該物質的普遍使用量比地球上多10倍, 韋伯望遠鏡就可以檢測到該物質。即使如此,為了讓氯氟烴出現,該行星還必須圍繞一顆特殊的恆星進行軌道運行,即白矮星。白矮星——它是像太陽這樣的恆星的最終命運,會最大化的加大污染信號。

【燒哦:12/12:托福閱讀解析與機經單字補充】

2015年12月12日,托福考試閱讀三篇文章分別是:
1. Comparing the Intelligence of Different Animal Species
(比較不同動物物種的智商)
2. Birds and Food Shortage(鳥類和食物短缺)
3. Changes of the Early Modern European States 
(早期現代歐洲國家的變化)。

從題材看,回歸經典的生物和人文社科類文章。這些話題內容都比較常見,第一篇動物智商相關文章,在2015-10-31的The Brain Size of Bottlenose Dolphins就曾考過,鳥類的文章更是比比皆是,但在具體考查內容和考法上,各篇文章又有所偏向,不能同一而論。今天,就第一篇文章做重點點評,幫助考生把握學術文章的行文框架,增加閱讀的方向感,同時搭建動物智商類文章的學術背景知識和相關英文表達。

學術論文-標準結構

托福,作為一門對學術內容的語言考查,具有非常標準的行文結構。第一篇文章Comparing the Intelligence of Different Animal Species,採用「前錯後駁」型論文結構,即前文豎起一個錯誤觀點/樹靶,後文進行批駁,該結構是「前錯後對」型文章結構的一部分,但由於字數限制,沒能對後文的正確觀點進行闡發,只停留在駁斥階段便結束了。此類文章,開頭部分需對錯誤觀點引入,常用的英文表達有:According to traditional/conventional view, It has long been accepted that…,earlier belief, long-held view,at one time。這裡尤其要注意「at onetime」,表示「曾經一度」,用於引出先前的錯誤觀點」,而非「在一次」這樣的表面翻譯。例如,今天第一篇文章Comparing the Intelligence of Different Animal Species,首段就利用「at one time」引出人們先前用於比較動物智商的錯誤理論和方法。

學術文章,段落內部的具體展開,通常以做試驗和舉例子的方式進行。本篇文章即以做試驗的方式打開。首先引入試驗對象,做簡單介紹,如引入dunnart,是一種生活在澳大利亞南部乾旱地區的有袋動物marsupial。然後,試驗步驟一一展開,最終得出試驗結論。記住:試驗步驟不重要,試驗結論才重要。因此,如果某個試驗步驟出現在最後總結題的某個選項裡,不予選擇。但是,雖然試驗步驟不重要,考生卻不能跳過試驗步驟直接看結論,因為如此便無法理解事物發展的來龍去脈,無法通曉因果關係。而這正是試驗類文章考查的重點難點所在。考生需要整體閱讀,前後聯繫,理順思路。考查的整體性因此大大加強,在某些極端題目的考查中,甚至需要考生通讀整段方能解題。

學術知識-常見考點

曾經一度,人們認為動物智商的比較,建立在動物學習秉性的基礎上,即動物從先前經歷中學習到的經驗轉移到下一難題處理中的能力差異。由此,人們設計出一系列的「形狀辨識試驗」:給試驗受體動物呈現不同形狀的刺激物,如三角形和正方形,只有選對三角形才能獲得食物犒勞,重複一定次數後,受體動物獲得這一辨識能力,然後再給受體動物呈現出第二組形狀辨識任務,圓形和六角形。因為有了第一組形狀辨識任務的經歷,所以動物在第二組任務中,出錯次數應該少於第一組。例如,在第一組的三角形和正方形的辨識中,動物犯了20次錯誤之後,才能穩定地找出三角形;而到了第二組試驗中,動物只犯15次錯誤後,便能穩定地找出圓形。在檢測學習能力的形狀辨識試驗中,不同動物的差異很大:老鼠松鼠們需要1800組辨識試驗的經歷後才能勉強學會分辨不同圖形,而恆河猴在400組辨識試驗後正確率就可以達到90%以上。研究人員認為,動物之所以擁有不同的辨識學習能力,是和它們的相對大腦大小有關。大腦相對越大,則學習能力越強,反之亦然。
