(r'rrrsic, caL engines, slaurming doors, whistling, coughiug, cryittg,

specch, [rreak it down into its snraller parls (words, prefixes, sulfrxes,
r:lt: ), de(ermine what they rnean, and figure out how to reassemble
llrc:rn in new ways.

r\sli lhe averirge person how a child lean-rs language and you'll

This type of thing is surprisingly couluorl. One stucly reports that
mothers mayrepeat as rnany as one third oIthcirchilclren's incorrcct
utteranccs without nlakil'lg any changes.ll
Do rtcnsts hcllt?
In light of this, it's perhaps r-rot surprisirrg that recasts are not a
rnagical elixir. They don't alrt,aj,s Itave a cliscernible eft'ect, at least
r-rot a reliable one.
In line 23 of or-rr speeclr sanrple, for instance, Adam's rnother
provides a recast that nrodels the possessive marke r -'s, which Adam
ther.r inclLrdes in his ncxt uttelance (line 2 4 ) but drops in the lollow-
ing one (line^2 5).

\/ith numbers lilie these, it woulcl be pretty hard for trvo-year-
olds to REL\ on their mother's recasts to learu language, In [act,
it nright even be^ misleading. Not only do^ tnothers^ leave^ the^ vast
majorit_v ol' their childre n's bad sentences alone (73.7^ percent in
Lhis saurple), thel' sometirnes partially repeat ancl change perfectly
gootl trtterances (1 3.7 percent).
Yor-r can see both ol'these things happening in the speech sarnple
rlr' jrrst lookcd at. On the one hand, Adam's urother mahes tlo attenpt

On the other hand, she recasts trvo utterances that were fine to

llunrer?rl in English (although^ some Ianguages do require tbis).
fo complictrte nlatters still fr-rrther, there are even tirnes rvhen

fatherese has not yet^ been investigated.)
Does tnotlrcrese lrclp?
Perhaps. As just^ noted, rnany of the features of^ motherese^ seem
designed to enhance the cornprehensiblity of the mother's speech (^) -
which n-ral<es sense, since most mothers want to coMMUNIcATE
with their children. Being exposed to highly cornprehensible speech
iu Lhe early stages of language acqr,risition can't hurt.
Horryever. that doesn't mean that lnotherese is Npcessanv lor
language acqr.risition to^ occur'. In^ fact,^ we lcnow^ that it^ cnr.rnol^ be
necessary. That's because there are communities and cultules in
vr'hich rrrotherese is r.rsed little if at all.2r
For example, in the coulse of hel extensive research in the
A[ro-r\merican rvorlting-class town o[ Tracl<ton during the ] 9 70s,
Shirle_v Brice Fleath noticed that ach.rlts there don't sirnplily their
speech at all n,hen adclressing children. They clon't use sin.rple words
or baby tallt, and they don't speak any slower t-han usual.
In fact, Heath reports, adults in Tracliton don't even see babies or
young children as suitable partners [or regular conversation. Except
[oL'war-nings, teasing, and orders, she says, "adults rarely address
speech specilically to very young children."25 YetTrackLon ctrildren
learn language.
This flies in tl-re face o[ standard (mis)conceptions about chil-
dreu aud language, I know. Errery societ)'has its myths, and one o[
ours is that children ueed special help learniug language. Steven
Piuker has attenpted to put this in perspective (^) by noting a bit of folklore (^) lron another culture.26 The ll(ung Sang of Aliica's
Kalahari Desert, he reports, believe that children must be taught
to sit, stand, and walli. O[ course, the !l(ung Sang are wrong about
tl'ral (^) - childreu sit, stand, and walk (^) on their own when they're [ead'. And rvc're n,rong about language (^) - children learn to (^) spcak with-
ouI any special help too. Annie lvlae, a'l'rackton resident, explains
it this n'ay when askecl horv she expected her grandson to learn to
talk:
I 78 Horv Cltildretr Lcartr Larryrutge

\-lnt rcnlly nmtters
Does this mean that children can learn languagc no rratter what
their circumstances?^ Not^ quite. There's^ at^ least^ one external con-
dition that nrust be rnet before language can be acquir:ed.^ Cltildrur

\bu can see n'hy this is so ilyou thiulc about the follorvir.rg simple

reported that hcarir-rg children gror,r,ing^ up in honres r,r'ith non-

But nolv irnagine a dilferent scenario. Let's say that after lis-

nalles lclr tlrings that I'ou olien looli at. touch, or plal'n'ith. (Recall

Senteuces lihe that are sinrply going to zip by without doing any
han-n or an1'good.
But quite a large portion ol'speech to children ts abor-rt whaI they
can see or hear, rvhat they r,r'ant to linott, abont. and what^ they have
just experienced or are about to experience.II [t's this tl,pe ol'speecIr
that provides childr:en rvith the raw rnaterinl thcy need to learn a
langnage. (Parcnts talie note!)
This r,,,orhs^ in Tracliton too, by tl-re way. Even though adtrlts there
address speech to childreu relatively infrequently, they are olten
r,r'ith children and they do speal< in front of them l"o others.12 So
loug as at least son-re ol those sentences are about the here and now
ar.rd thercfore are comprehensible to children. the key condition for
languagc acquisition is in place. (Do^ young Trackton children pay
attentiou to those sorts of seutencesT Evidently they do, since Heath
reports that they frequently repeat them.)
But regardless o[ whether it's Seattle or Tracl<tor.r, we still have
to ask "Then^ what7" You could procluce easy-to-understand sen-
tences in front o[ a cat lor all niue ol'its lirres, and it still wouldn'L
learn English. Obviouslli thcre's nrore [o language leanting than
just hearing certain types oI sentences in certain l"ypes of contexts.
That sonrething cannot be observed so directli', though, because it's
inside thc child's lrcad.

The job^ ol'lar.rguage acquisition reseArchers is to figr-rre out pr:ecisely
rurhat's ir.r the little blacli box labeled "acqr-risition clevice" that tnrns
erperiencc into knon,ledge.
To sorue extent, of course, the acquisition clevice is an abstraction.
It's not literally a box in the brain. In fact, it's likely tbat it"s parts
are splead out in diflerent regious of the brain, just as books about
language can be lbund iu dil'l'erent parts ol'a library.
For novv, the key to thinliing abor.rt the acquisitiou device is to
lbcr.ts or-r what those parts are and how tlrel' yy6.L. And here there
are t\t'o verJ'dillerent v'ews.

and rthat to look for. [n particular, it tells ther.n that alllangnages are

V/hat might these clr.res looh like? Oue possibility is that they
involve inlblmation abouI the type oInreaning most olten associater]
r'r'ith particular^ nrorcl classes. For example, the acqr-risition der,ice
might "tell"^ children that rvords relerring (o^ concrcte thiugs nrust
be uonLrs. So langr-rage learners r'r'ould [<nolv right arvay that words
lilie dog, I71ry, /rorrse, and trzc belong to that n,ord class.
This might jr-rst^ be enough to get stalted. Once clrildren knevtt
