27、tteron AnswerSheet 2.What happens whenalanguage has nowords fornumbers?Numbers donot exist inall cultures. There are numberless hunter-gatherers embeddeddeepinAmazonia, living along branches of the world ls argestriver tree. Instead of using words forprecisequantities, these people rely exclusivelyo

28、n termsanalogous to “ afewo”r “ some.”Incontrast, our own livesare governedby numbers. As you readthis, youare likely aware ofwhat time it is,how old you are,yourchecking account balance,yourweight and soon. The exact(andexacting) numberswe think withimpact everything from our schedules toour self-e

29、steem.But, in ahistorical sense,numerically fixatedpeople like usare the unusual ones. For the bulkof our species approximately 200,000-year lifespan, we had no meansof precisely representingquantities. Whatsmore, the7,000 or solanguages that existtoday vary dramatically in how theyutilize numbers.S

30、peakersof anumeric, or numberless, languagesoffer a window into how the invention ofnumbers reshapedthe human experience. In anew book, I explored the ways in which humansinventednumbers,and how numberssubsequently played acritical role inother milestones,fromthe advent of agriculture to the genesis

31、of writing.Cultures withoutnumbers, orwithonlyoneortwoprecisenumbers, includethe Mundurukuand Pirah? inAmazonia.ResearchershavealsostudiedsomeadultsinNicaragua who werenevertaught number words.Without numbers, healthy human adults struggle toprecisely differentiate and recall quantitiesas lowas four

32、.In anexperiment, aresearcherwill place nuts into acan one at atime,thenremovethemone by one. The person watching isaskedto signal when all the nuts have beenremoved.Responsessuggest that anumeric people have sometrouble keepingtrack of how many nuts remaininthe can, evenif there are only four or fi

33、veintotal.This andmany otherexperiments have convergedupon a simple conclusion: Whenpeople donot have numberwords,they struggle to makequantitative distinctions that probably seemnaturaltosomeone like youor me.Whileonly asmall portion of the world lasnguagesare anumeric ornearly anumeric,they demons

34、trate that numberwords are not a human universal.It is worth stressing that these anumeric people are cognitivelynormal,well-adapted to theenvirons theyhave dominated for centuries.As the childof missionaries, Ispent some of my youthliving with anumeric indigenous people, the aforementioned Pirah? w

35、ho live along the sinuousbanks of the black Maici River.Like otheroutsiders,I was continually impressedby theirsuperiorunderstandingof theriverine ecology weshared.Yet numberless people struggle withtasks that require precise discriminationbetweenquantities.Perhapsthis should be unsurprising.Afteral

36、l, without counting,how can someone tellwhetherthere are,say, sevenoreight coconutsin atree?Such seemingly straightforward distinctionsbecomeblurry through numberlesseyes.This conclusion isechoedby work withanumeric children inindustrialized societies.Prior to being spoon-fed number words, childrenc

37、an only approximately discriminatequantities beyond three. We must be handed the cognitive tools of numbers before we canconsistently and easily recognize higher quantities.In fact, acquiring the exact meaning of number words is a painstaking process that takeschildren years. Initially, kids learn n

38、umbers much like they learn letters. They recognize thatnumbers are organizedsequentially, but have littleawareness of what each individual numbermeans.Withtime,they start tounderstand that agivennumber represents aquantity greaterby one than theprecedingnumber. This successorprinciple ispart of the

39、 foundation of our numerical cognition,but requires extensive practice tounderstand.None of us, then,is really anumbers person.We are not predisposedto handle quantitativedistinctions adroitly. Inthe absence of the cultural traditions that infuse our liveswith numbers frominfancy,we would all strugg

40、le withevenbasic quantitative distinctions.Numberwords and writtennumerals transform our quantitativereasoning as theyare coaxedinto our cognitive experience by our parents, peers and school teachers. The processseems sonormal that we sometimesthink of it asa natural part of growing up, but it is no

41、t. Humanbrainscomeequipped with certain quantitativeinstincts that are refinedwith age,but these instinctsareverylimited.For instance, evenat birth we are capable of distinguishing betweentwomarkedlydifferent quantities forinstance, eight from 16 things.But we are not the only speciescapable of such

42、 abstractions. Compared tochimpsand otherprimates,our numerical instincts are not as remarkableas many presume. Weevenshare somebasicinstinctual quantitative reasoning with distant nonmammalian relativeslike birds. Indeed,work withsome otherspecies,including parrots, suggeststhey too canrefine their

43、quantitative thought if theyare introducedto the cognitivepower tools we call numbers.So, how didwe everinvent unnaturalnumbers inthe first place?The answer is,literally,at your fingertips.The bulk of the worlds languages use base-10, base-20or base-5 numbersystems.That is,these smallernumbers are t

44、he basis of largernumbers. Englishisabase-10 or decimal language,as evidencedby words like 14 (four +10) and 31 (threex10 + one).We speak a decimal language because an ancestral tongue, proto-Indo-European,wasdecimallybased. Proto-Indo-European wasdecimally orientedbecause, asin somany cultures, our

45、linguistic ancestors handsservedas the gateway to realizations likefive fingers on thishand is thesame asfive fingers onthat hand.Such transient thoughts were manifestedinto words and passeddown across generations. This iswhy theword fiveinmany languages isderivedfrom the wordforhand.Most number sys

46、tems, then, are the by-product of two key factors: the human capacity forlanguage and our propensity for focusing on our hands and fingers. This manual fixation anindirect by-product of walking upright on twolegshas helped yieldnumbers in most cultures,butnot all.Cultures without numbersalso offerin

47、sight into the cognitive influence of particular numerictraditions.Considerwhat time itis. Your day is ruledby minutes andseconds, but these entitiesarenot real inany physical sense and are nonexistent tonumberless people.Minutes andseconds arethe verbal and written vestiges of an uncommon base-60 n

48、umber system used in Mesopotamiamillennia ago. They reside inour minds, numerical artifactsthat not all humans inherit conceptually.Research on the language of numbersshows,more and more,that one of our specieskeycharacteristics is tremendous linguistic and cognitive diversity. While there are undou

49、btedlycognitive commonalities across all human populations, our radically varied cultures fosterprofoundly differentcognitive experiences.Ifwe are totruly understand how muchour cognitivelivesdiffercross-culturally,we must continually sound the depths of our specieslinguistic diversity.36.It is wort

Compared withother mammals,our numerical instincts are not asremarkable as many assume.38. It is worth stressing that these anumeric people are cognitively( 在认知方
