My subject today is learning.
0
15260
3000
Danas je moja tema učenje.
00:18
And in that spirit, I want to spring on you all a pop quiz.
1
18260
3000
I u tom duhu želim vam svima postaviti pitanje.
00:21
Ready?
2
21260
2000
Spremni?
00:23
When does learning begin?
3
23260
3000
Kada počinje učenje?
00:26
Now as you ponder that question,
4
26260
2000
Sada dok razmišljate o tom pitanju,
00:28
maybe you're thinking about the first day of preschool
5
28260
2000
možda mislite o prvom danu u maloj školi
00:30
or kindergarten,
6
30260
2000
ili vrtiću,
00:32
the first time that kids are in a classroom with a teacher.
7
32260
3000
prvi put kada su djeca u razredu s učiteljem.
00:35
Or maybe you've called to mind the toddler phase
8
35260
3000
Ili vam je možda pala na pamet razvojna faza
00:38
when children are learning how to walk and talk
9
38260
3000
kada djeca uče kako hodati, govoriti
00:41
and use a fork.
10
41260
2000
i upotrebljavati vilicu.
00:43
Maybe you've encountered the Zero-to-Three movement,
11
43260
3000
Možda ste se susreli sa Nula do tri pokretom
00:46
which asserts that the most important years for learning
12
46260
3000
koji ističe da su najvažnije godine za učenje
00:49
are the earliest ones.
13
49260
2000
one najranije.
00:51
And so your answer to my question would be:
14
51260
3000
I tako bi vaš odgovor na moje pitanje bio:
00:54
Learning begins at birth.
15
54260
2000
Učenje počinje rođenjem.
00:56
Well today I want to present to you
16
56260
2000
Danas vam želim predstaviti
00:58
an idea that may be surprising
17
58260
3000
ideju koja može iznenaditi
01:01
and may even seem implausible,
18
61260
3000
i čak se može činiti nevjerojatnom,
01:04
but which is supported by the latest evidence
19
64260
2000
ali podržana je posljednjim dokazom
01:06
from psychology and biology.
20
66260
3000
iz psihologije i biologije.
01:09
And that is that some of the most important learning we ever do
21
69260
3000
A to je da se neka od najvažnijih učenja koja nam se ikada dogode,
01:12
happens before we're born,
22
72260
2000
događaju prije nego što se rodimo
01:14
while we're still in the womb.
23
74260
3000
dok smo još u maternici.
01:17
Now I'm a science reporter.
24
77260
2000
Ja sam znanstveni novinar.
01:19
I write books and magazine articles.
25
79260
2000
Pišem knjige i članke u časopisima.
01:21
And I'm also a mother.
26
81260
2000
I također sam majka.
01:23
And those two roles came together for me
27
83260
3000
I te su se dvije uloge stopile
01:26
in a book that I wrote called "Origins."
28
86260
3000
u knjizi koju sam napisala pod imenom Podrijetlo.
01:29
"Origins" is a report from the front lines
29
89260
3000
„Podrijetlo“ su izvještaj s prvih linija
01:32
of an exciting new field
30
92260
2000
uzbudljivog novog područja
01:34
called fetal origins.
31
94260
2000
zvanog fetalno podrijetlo.
01:36
Fetal origins is a scientific discipline
32
96260
3000
Fetalno podrijetlo je znanstvena disciplina
01:39
that emerged just about two decades ago,
33
99260
3000
koja se pojavila prije dva desetljeća
01:42
and it's based on the theory
34
102260
3000
i zasnovana je na teoriji
01:45
that our health and well-being throughout our lives
35
105260
3000
da je na naše zdravlje i dobrobit kroz naš život
01:48
is crucially affected
36
108260
2000
presudno djelovalo
01:50
by the nine months we spend in the womb.
37
110260
3000
devet mjeseci koje smo proveli u maternici.
01:53
Now this theory was of more than just intellectual interest to me.
38
113260
4000
Ova teorija bila je više od intelektualnog interesa za mene.
01:57
I was myself pregnant
39
117260
2000
Bila sam trudna
01:59
while I was doing the research for the book.
40
119260
3000
dok sam radila istraživanje za knjigu.
02:02
And one of the most fascinating insights
41
122260
2000
I jedno od najfascinantnijih shvaćanja
02:04
I took from this work
42
124260
2000
koje sam dobila ovim radom
02:06
is that we're all learning about the world
43
126260
3000
je da svi učimo o svijetu
02:09
even before we enter it.
44
129260
3000
prije nego što uđemo u njega.
02:12
When we hold our babies for the first time,
45
132260
2000
Kada prvi put držimo naše bebe,
02:14
we might imagine that they're clean slates,
46
134260
3000
možemo zamisliti da su na svježem početku,
02:17
unmarked by life,
47
137260
2000
neobilježene životom,
02:19
when in fact, they've already been shaped by us
48
139260
3000
dok su zapravo već bile oblikovane od nas
02:22
and by the particular world we live in.
49
142260
4000
i specifičnog svijeta u kojem živimo.
02:26
Today I want to share with you some of the amazing things
50
146260
2000
Danas želim podijeliti s vama neke nevjerojatne stvari
02:28
that scientists are discovering
51
148260
2000
koje znanstvenici otkrivaju
02:30
about what fetuses learn
52
150260
2000
o tome što fetusi uče
02:32
while they're still in their mothers' bellies.
53
152260
3000
dok su još u majčinim trbusima.
02:36
First of all,
54
156260
2000
Prije svega,
02:38
they learn the sound of their mothers' voices.
55
158260
3000
nauče zvuk majčina glasa.
02:41
Because sounds from the outside world
56
161260
3000
Zato što zvukovi iz vanjskog svijeta
02:44
have to travel through the mother's abdominal tissue
57
164260
3000
moraju putovati kroz majčino trbušno tkivo
02:47
and through the amniotic fluid that surrounds the fetus,
58
167260
4000
i kroz amnionsku tekućinu koja okružuje fetus,
02:51
the voices fetuses hear,
59
171260
2000
zvukovi koje fetus čuje,
02:53
starting around the fourth month of gestation,
60
173260
3000
počevši oko četvrtog mjeseca gestacije
02:56
are muted and muffled.
61
176260
2000
su bezvučni i prigušeni.
02:58
One researcher says
62
178260
2000
Jedan istraživač kaže
03:00
that they probably sound a lot like the the voice of Charlie Brown's teacher
63
180260
3000
da vjerojatno zvuče poput glasa učiteljice Charlieja Browna
03:03
in the old "Peanuts" cartoon.
64
183260
3000
u starom Kikiriki crtiću.
03:06
But the pregnant woman's own voice
65
186260
3000
Ali glas trudne žene
03:09
reverberates through her body,
66
189260
2000
odjekuje kroz njeno tijelo,
03:11
reaching the fetus much more readily.
67
191260
3000
dostižući fetus spremnije.
03:14
And because the fetus is with her all the time,
68
194260
3000
I zato što je fetus s njom cijelo vrijeme,
03:17
it hears her voice a lot.
69
197260
3000
često čuje njen glas.
03:20
Once the baby's born, it recognizes her voice
70
200260
3000
Jednom kad se dijete rodi, prepoznaje njen glas
03:23
and it prefers listening to her voice
71
203260
2000
i preferira slušanje njenog glasa
03:25
over anyone else's.
72
205260
2000
u odnosu na bilo koji drugi.
03:27
How can we know this?
73
207260
2000
Kako to možemo znati?
03:29
Newborn babies can't do much,
74
209260
2000
Novorođenčad ne može mnogo učiniti,
03:31
but one thing they're really good at is sucking.
75
211260
3000
ali jedna stvar u kojoj je zaista dobra je sisanje.
03:34
Researchers take advantage of this fact
76
214260
3000
Istraživači su iskoristili prednost ove činjenice
03:37
by rigging up two rubber nipples,
77
217260
3000
lažiranjem dvije gumene bradavice
03:40
so that if a baby sucks on one,
78
220260
2000
tako da ako beba siše jednu,
03:42
it hears a recording of its mother's voice
79
222260
2000
čuje snimku majčinog glasa
03:44
on a pair of headphones,
80
224260
2000
na slušalicama,
03:46
and if it sucks on the other nipple,
81
226260
2000
a ako siše na drugoj
03:48
it hears a recording of a female stranger's voice.
82
228260
4000
čuje snimku glasa strane žene.
03:52
Babies quickly show their preference
83
232260
3000
Bebe su brzo pokazale sklonost
03:55
by choosing the first one.
84
235260
3000
odabirući prvu.
03:58
Scientists also take advantage of the fact
85
238260
3000
Znanstvenici su također iskoristili prednost činjenice
04:01
that babies will slow down their sucking
86
241260
2000
da će bebe usporiti sisanje
04:03
when something interests them
87
243260
2000
kada ih nešto zainteresira
04:05
and resume their fast sucking
88
245260
2000
i nastaviti brzo sisanje
04:07
when they get bored.
89
247260
3000
kad im postane dosadno.
04:10
This is how researchers discovered
90
250260
2000
Evo kako su istraživači to otkrili,
04:12
that, after women repeatedly read aloud
91
252260
3000
nakon što su žene ponovno čitale na glas
04:15
a section of Dr. Seuss' "The Cat in the Hat" while they were pregnant,
92
255260
4000
odlomak iz Dr. Seussovog „Mačka u šeširu“ dok su bile trudne,
04:19
their newborn babies recognized that passage
93
259260
3000
njihova novorođenčad je prepoznala taj odlomak
04:22
when they hear it outside the womb.
94
262260
3000
kad ga je čula van maternice.
04:25
My favorite experiment of this kind
95
265260
3000
Moj omiljeni pokus ove vrste
04:28
is the one that showed that the babies
96
268260
2000
je onaj koji je pokazao da su bebe
04:30
of women who watched a certain soap opera
97
270260
2000
žena koje su gledale određenu sapunicu
04:32
every day during pregnancy
98
272260
3000
svaki dan tijekom trudnoće
04:35
recognized the theme song of that show
99
275260
3000
prepoznale uvodnu pjesmu te serije
04:38
once they were born.
100
278260
3000
kad su se rodila.
04:41
So fetuses are even learning
101
281260
2000
Dakle, fetusi čak uče
04:43
about the particular language that's spoken
102
283260
3000
o određenom jeziku koji se govori
04:46
in the world that they'll be born into.
103
286260
2000
u svijetu u kojem će biti rođeni.
04:48
A study published last year
104
288260
3000
Studija objavljena prošle godine
04:51
found that from birth, from the moment of birth,
105
291260
3000
otkrila je da od rođenja, od trenutka rođenja
04:54
babies cry in the accent
106
294260
2000
djeca plaču naglaskom
04:56
of their mother's native language.
107
296260
3000
majčinog materinskog jezika.
04:59
French babies cry on a rising note
108
299260
3000
Francuske bebe plaču povišenim tonom
05:02
while German babies end on a falling note,
109
302260
3000
dok njemačka djeca završavaju nižim tonom
05:05
imitating the melodic contours
110
305260
2000
imitirajući melodijske obrise
05:07
of those languages.
111
307260
2000
tih jezika.
05:09
Now why would this kind of fetal learning
112
309260
2000
Zašto bi ovakva vrsta fetalnog učenja
05:11
be useful?
113
311260
2000
bila korisna?
05:13
It may have evolved to aid the baby's survival.
114
313260
3000
Možda je evoluirala kako bi pomogla bebinom preživljavanju.
05:16
From the moment of birth,
115
316260
2000
Od trenutka rođenja
05:18
the baby responds most to the voice
116
318260
2000
beba najviše reagira na glas
05:20
of the person who is most likely to care for it --
117
320260
2000
osobe koja najviše brine za nju–
05:22
its mother.
118
322260
2000
svoje majke.
05:24
It even makes its cries
119
324260
2000
Čak svoj plač
05:26
sound like the mother's language,
120
326260
2000
čini takvim da zvuči poput majčinog jezika
05:28
which may further endear the baby to the mother,
121
328260
3000
koji može dodatno omiliti bebu majci
05:31
and which may give the baby a head start
122
331260
2000
i koji može bebi dati prednost
05:33
in the critical task
123
333260
2000
u kritičnom zadatku
05:35
of learning how to understand and speak
124
335260
3000
učenja kako razumjeti i govoriti
05:38
its native language.
125
338260
2000
svoj materinski jezik.
05:40
But it's not just sounds
126
340260
2000
Ali nisu samo zvukovi ti
05:42
that fetuses are learning about in utero.
127
342260
2000
o kojima fetus uči u maternici.
05:44
It's also tastes and smells.
128
344260
3000
Tu su i okusi i mirisi.
05:47
By seven months of gestation,
129
347260
2000
Do sedmog mjeseca gestacije,
05:49
the fetus' taste buds are fully developed,
130
349260
2000
fetusovi okusni pupoljci su potpuno razvijeni
05:51
and its olfactory receptors, which allow it to smell,
131
351260
3000
i njegovi njušni receptori koji mu dozvoljavaju da njuši
05:54
are functioning.
132
354260
2000
funkcioniraju.
05:56
The flavors of the food a pregnant woman eats
133
356260
3000
Okus hrane koju trudna žena jede
05:59
find their way into the amniotic fluid,
134
359260
2000
pronalazi put do amnionske tekućine
06:01
which is continuously swallowed
135
361260
2000
koju fetus konstantno
06:03
by the fetus.
136
363260
2000
guta.
06:05
Babies seem to remember and prefer these tastes
137
365260
3000
Čini se da bebe pamte i preferiraju te okuse
06:08
once they're out in the world.
138
368260
3000
kad jednom izađu u svijet.
06:11
In one experiment, a group of pregnant women
139
371260
3000
U jednom pokusu, grupa trudnih žena
06:14
was asked to drink a lot of carrot juice
140
374260
2000
je zamoljena da pije mnogo soka od mrkve
06:16
during their third trimester of pregnancy,
141
376260
3000
tijekom trećeg tromjesečja trudnoće
06:19
while another group of pregnant women
142
379260
2000
dok je druga grupa trudnih žena
06:21
drank only water.
143
381260
2000
pila samo vodu.
06:23
Six months later, the women's infants
144
383260
3000
Šest mjeseci poslije bebama
06:26
were offered cereal mixed with carrot juice,
145
386260
3000
su ponuđene žitarice sa sokom od mrkve
06:29
and their facial expressions were observed while they ate it.
146
389260
4000
i promatrani su izrazi njihovih lica dok su jele.
06:33
The offspring of the carrot juice drinking women
147
393260
2000
Potomci žena koje su pile sok od mrkve
06:35
ate more carrot-flavored cereal,
148
395260
2000
pojeli su više žitarica s okusom mrkve
06:37
and from the looks of it,
149
397260
2000
i prema izrazima
06:39
they seemed to enjoy it more.
150
399260
2000
činilo se da više uživaju u tome.
06:41
A sort of French version of this experiment
151
401260
3000
Francuska verzija ovog pokusa
06:44
was carried out in Dijon, France
152
404260
2000
održana je u Dijonu u Francuskoj
06:46
where researchers found
153
406260
2000
gdje su istraživači otkrili
06:48
that mothers who consumed food and drink
154
408260
3000
da su bebe majki koje su konzumirale hranu i piće
06:51
flavored with licorice-flavored anise during pregnancy
155
411260
5000
s okusom slatkog korijena anisa tijekom trudnoće
06:56
showed a preference for anise
156
416260
2000
pokazale skolonost anisu
06:58
on their first day of life,
157
418260
2000
prvog dana života
07:00
and again, when they were tested later,
158
420260
2000
i ponovo kada su kasnije bila testirana,
07:02
on their fourth day of life.
159
422260
2000
četvrtog dana života.
07:04
Babies whose mothers did not eat anise during pregnancy
160
424260
4000
Bebe čije majke nisu jele anis tijekom trudnoće
07:08
showed a reaction that translated roughly as "yuck."
161
428260
4000
pokazale su reakciju koja je grubo prevedena kao „fuj“.
07:12
What this means
162
432260
2000
To znači
07:14
is that fetuses are effectively being taught by their mothers
163
434260
2000
da su fetusi učinkovito naučeni od strane majki
07:16
about what is safe and good to eat.
164
436260
3000
o tome što je sigurno i dobro za jelo.
07:19
Fetuses are also being taught
165
439260
2000
Fetusi su također poučeni
07:21
about the particular culture that they'll be joining
166
441260
3000
o određenoj kulturi kojoj će se pridružiti
07:24
through one of culture's most powerful expressions,
167
444260
3000
kroz jednu od najmoćnijih kulturnih izražaja,
07:27
which is food.
168
447260
2000
a to je hrana.
07:29
They're being introduced to the characteristic flavors and spices
169
449260
3000
Upoznati su s karakteristikama okusa i začina
07:32
of their culture's cuisine
170
452260
2000
kuhinje njihove kulture
07:34
even before birth.
171
454260
3000
čak i prije rođenja.
07:37
Now it turns out that fetuses are learning even bigger lessons.
172
457260
3000
Čini se da fetusi uče čak i veće lekcije.
07:40
But before I get to that,
173
460260
2000
Ali prije nego što dođem do toga,
07:42
I want to address something that you may be wondering about.
174
462260
4000
želim vas uputiti u nešto o čemu ste možda razmišljali.
07:46
The notion of fetal learning
175
466260
2000
Značaj fetalnog učenja
07:48
may conjure up for you attempts to enrich the fetus --
176
468260
3000
vam može prizvati pokušaje da obogatite fetus –
07:51
like playing Mozart through headphones
177
471260
2000
poput puštanja Mozarta preko slušalica
07:53
placed on a pregnant belly.
178
473260
2000
smještenih na trudničkom trbuhu.
07:55
But actually, the nine-month-long process
179
475260
3000
Ali zapravo, devet mjeseci dug proces
07:58
of molding and shaping that goes on in the womb
180
478260
3000
kalupljenja i oblikovanja koji se odvija u maternici
08:01
is a lot more visceral and consequential than that.
181
481260
4000
je mnogo organskiji i dosljedniji od toga.
08:05
Much of what a pregnant woman encounters in her daily life --
182
485260
4000
Mnogo toga što trudnica susreće tijekom svog dnevnog života –
08:09
the air she breathes,
183
489260
2000
zrak koji udiše,
08:11
the food and drink she consumes,
184
491260
2000
hrana i piće koju konzumira,
08:13
the chemicals she's exposed to,
185
493260
2000
kemikalije kojima je izložena
08:15
even the emotions she feels --
186
495260
2000
čak i emocije koje osjeća –
08:17
are shared in some fashion with her fetus.
187
497260
3000
su podijeljene na neki način s njenim fetusom.
08:20
They make up a mix of influences
188
500260
3000
Oni čine mješavinu utjecaja
08:23
as individual and idiosyncratic
189
503260
2000
pojedinačno i idiosinkrastički,
08:25
as the woman herself.
190
505260
2000
kao i žena sama.
08:27
The fetus incorporates these offerings
191
507260
2000
Fetus objedinjuje te ponude
08:29
into its own body,
192
509260
2000
u svoje vlastito tijelo,
08:31
makes them part of its flesh and blood.
193
511260
3000
čini ih dijelom svoje krvi i mesa.
08:34
And often it does something more.
194
514260
2000
I često čini nešto više.
08:36
It treats these maternal contributions
195
516260
3000
Tretira te majčine doprinose
08:39
as information,
196
519260
2000
kao informaciju
08:41
as what I like to call biological postcards
197
521260
2000
kao nešto što volim zvati biološkim razglednicama
08:43
from the world outside.
198
523260
3000
iz svijeta koji je vani.
08:46
So what a fetus is learning about in utero
199
526260
3000
Dakle, ono što fetus uči u maternici
08:49
is not Mozart's "Magic Flute"
200
529260
2000
nije Mozartova „Čarobna frula“
08:51
but answers to questions much more critical to its survival.
201
531260
4000
nego odgovori na pitanja koja su bitnija za njegovo preživljavanje.
08:55
Will it be born into a world of abundance
202
535260
2000
Hoće li biti rođen u svijetu izobilja
08:57
or scarcity?
203
537260
2000
ili nestašice?
08:59
Will it be safe and protected,
204
539260
3000
Hoće li biti siguran i zaštićen
09:02
or will it face constant dangers and threats?
205
542260
3000
ili će se suočavati s konstantnim opasnostima i prijetnjama?
09:05
Will it live a long, fruitful life
206
545260
2000
Hoće li živjeti dugim, plodnim životom
09:07
or a short, harried one?
207
547260
3000
ili kratkim, uništenim životom?
09:10
The pregnant woman's diet and stress level in particular
208
550260
3000
Pogotovo trudnička dijeta i razina stresa
09:13
provide important clues to prevailing conditions
209
553260
3000
pružaju važne naznake o prevladavajućim uvjetima
09:16
like a finger lifted to the wind.
210
556260
3000
poput prsta podignutog u zrak.
09:19
The resulting tuning and tweaking
211
559260
2000
To podešavanje i ugađanje
09:21
of a fetus' brain and other organs
212
561260
3000
fetusovog mozga i drugih organa
09:24
are part of what give us humans
213
564260
2000
je dio onoga što daje nama ljudima
09:26
our enormous flexibility,
214
566260
2000
ogromnu fleksibilnost,
09:28
our ability to thrive
215
568260
2000
našu sposobnost da napredujemo
09:30
in a huge variety of environments,
216
570260
2000
u velikoj raznovrsnosti okoliša,
09:32
from the country to the city,
217
572260
2000
od sela do grada,
09:34
from the tundra to the desert.
218
574260
3000
od tundre do pustinje.
09:37
To conclude, I want to tell you two stories
219
577260
2000
Kako bih zaključila želim vam ispričati dvije priče
09:39
about how mothers teach their children about the world
220
579260
3000
o tome kako majke uče svoju djecu o svijetu
09:42
even before they're born.
221
582260
3000
prije nego što se rode.
09:46
In the autumn of 1944,
222
586260
2000
U jesen 1944.,
09:48
the darkest days of World War II,
223
588260
3000
najmračnijim danima 2. svjetskog rata,
09:51
German troops blockaded Western Holland,
224
591260
3000
njemačke su trupe blokirale zapadnu Nizozemsku,
09:54
turning away all shipments of food.
225
594260
3000
udaljivši sve pošiljke hrane.
09:57
The opening of the Nazi's siege
226
597260
2000
Otvaranje nacističke opsade
09:59
was followed by one of the harshest winters in decades --
227
599260
3000
pratila je jedna od najtežih zima u tom desetljeću –
10:02
so cold the water in the canals froze solid.
228
602260
4000
tako hladna da se voda u kanalima čvrsto smrznula.
10:06
Soon food became scarce,
229
606260
2000
Ubrzo je hrana postala oskudna
10:08
with many Dutch surviving on just 500 calories a day --
230
608260
4000
i mnogo je Nizozemaca preživljavalo sa samo 500 kalorija na dan –
10:12
a quarter of what they consumed before the war.
231
612260
3000
četvrtina onoga što su konzumirali prije rata.
10:15
As weeks of deprivation stretched into months,
232
615260
3000
Kako su se tjedni siromaštva rastegnuli na mjesece,
10:18
some resorted to eating tulip bulbs.
233
618260
3000
neki su pribjegli jedenju lukovica tulipana.
10:21
By the beginning of May,
234
621260
2000
Početkom svibnja,
10:23
the nation's carefully rationed food reserve
235
623260
2000
narod je pažljivo odmjerio da su rezerve hrane
10:25
was completely exhausted.
236
625260
2000
potpuno istrošene.
10:27
The specter of mass starvation loomed.
237
627260
3000
Prijetila je avet masovnog gladovanja.
10:30
And then on May 5th, 1945,
238
630260
3000
I tada, 5. svibnja 1945.,
10:33
the siege came to a sudden end
239
633260
2000
opsada je odjednom završila
10:35
when Holland was liberated
240
635260
2000
kada je Nizozemska oslobođena
10:37
by the Allies.
241
637260
2000
uz pomoć saveznika.
10:39
The "Hunger Winter," as it came to be known,
242
639260
3000
„Gladna zima“, kako je postala poznata,
10:42
killed some 10,000 people
243
642260
2000
ubila je oko 10 000 ljudi
10:44
and weakened thousands more.
244
644260
2000
i oslabila još tisuće.
10:46
But there was another population that was affected --
245
646260
3000
Ali postojala je još jedna populacija na koju je to utjecalo –
10:49
the 40,000 fetuses
246
649260
2000
40 000 fetusa
10:51
in utero during the siege.
247
651260
3000
u maternicama tijekom opsade.
10:54
Some of the effects of malnutrition during pregnancy
248
654260
2000
Neke posljedice pothranjenosti tijekom trudnoće
10:56
were immediately apparent
249
656260
2000
odmah su se vidjele
10:58
in higher rates of stillbirths,
250
658260
2000
u većem postotku mrtvorođenčadi,
11:00
birth defects, low birth weights
251
660260
2000
urođenih mana, niskih porođajnih težina
11:02
and infant mortality.
252
662260
2000
i smrtnosti novorođenčadi.
11:04
But others wouldn't be discovered for many years.
253
664260
3000
Ali ostale nisu bile otkrivene mnogo godina.
11:07
Decades after the "Hunger Winter,"
254
667260
2000
Desetljećima nakon „Gladne zime“
11:09
researchers documented
255
669260
2000
istraživači su dokumentirali
11:11
that people whose mothers were pregnant during the siege
256
671260
4000
da su ljudi čije su majke bile trudne za vrijeme opsade
11:15
have more obesity, more diabetes
257
675260
2000
bili gojazniji, češće imali dijabetes
11:17
and more heart disease in later life
258
677260
3000
i više srčanih bolesti kasnije u životu
11:20
than individuals who were gestated under normal conditions.
259
680260
3000
od pojedinaca koji su rođeni u normalnim uvjetima.
11:23
These individuals' prenatal experience of starvation
260
683260
4000
Ta pojedinačna prenatalna iskustva izgladnjivanja
11:27
seems to have changed their bodies
261
687260
2000
očito su promijenila njihova tijela
11:29
in myriad ways.
262
689260
2000
na bezbroj načina.
11:31
They have higher blood pressure,
263
691260
2000
Imaju povišen krvni tlak,
11:33
poorer cholesterol profiles
264
693260
2000
lošije profile kolesterola
11:35
and reduced glucose tolerance --
265
695260
2000
i smanjenu toleranciju na glukozu –
11:37
a precursor of diabetes.
266
697260
3000
preteča dijabetesa.
11:40
Why would undernutrition in the womb
267
700260
2000
Zašto bi pothranjivanje u maternici
11:42
result in disease later?
268
702260
2000
kasnije rezultiralo bolešću?
11:44
One explanation
269
704260
2000
Jedno objašnjenje
11:46
is that fetuses are making the best of a bad situation.
270
706260
3000
je da fetusi izvlače najbolje iz loše situacije.
11:49
When food is scarce,
271
709260
2000
Kada hrane nema
11:51
they divert nutrients towards the really critical organ, the brain,
272
711260
3000
oni skreću hranjive tvari prema zaista kritičnom organu, mozgu
11:54
and away from other organs
273
714260
2000
i podalje od ostalih organa
11:56
like the heart and liver.
274
716260
2000
poput srca i jetre.
11:58
This keeps the fetus alive in the short-term,
275
718260
3000
To drži fetus živim kratko vrijeme,
12:01
but the bill comes due later on in life
276
721260
3000
ali račun dolazi na naplatu kasnije u životu
12:04
when those other organs, deprived early on,
277
724260
2000
kada ti ostali organi, uskraćeni ranije,
12:06
become more susceptible to disease.
278
726260
3000
postanu podložniji bolesti.
12:09
But that may not be all that's going on.
279
729260
3000
Ali to možda nije sve što se zbiva.
12:12
It seems that fetuses are taking cues
280
732260
2000
Čini se da fetusi primaju znakove
12:14
from the intrauterine environment
281
734260
3000
iz intrauterine okoline
12:17
and tailoring their physiology accordingly.
282
737260
2000
i prilagođavaju svoju fiziologiju prema tome.
12:19
They're preparing themselves
283
739260
2000
Pripremaju se
12:21
for the kind of world they will encounter
284
741260
2000
za vrstu svijeta u koji će ući
12:23
on the other side of the womb.
285
743260
2000
na drugoj strani maternice.
12:25
The fetus adjusts its metabolism
286
745260
2000
Fetus prilagođava svoj metabolizam
12:27
and other physiological processes
287
747260
3000
i druge fiziološke procese
12:30
in anticipation of the environment that awaits it.
288
750260
3000
predosjećajući okolinu koja ga čeka.
12:33
And the basis of the fetus' prediction
289
753260
3000
I osnova fetusove pretpostavke
12:36
is what its mother eats.
290
756260
2000
je ono što majka jede.
12:38
The meals a pregnant woman consumes
291
758260
2000
Obroci koje trudnica konzumira
12:40
constitute a kind of story,
292
760260
2000
sadrže neku vrstu priče,
12:42
a fairy tale of abundance
293
762260
2000
bajku o izobilju
12:44
or a grim chronicle of deprivation.
294
764260
3000
ili strašnu kroniku siromaštva.
12:47
This story imparts information
295
767260
3000
Ova priča pruža informaciju
12:50
that the fetus uses
296
770260
2000
koju fetus koristi
12:52
to organize its body and its systems --
297
772260
2000
kako bi organizirao svoje tijelo i sistem –
12:54
an adaptation to prevailing circumstances
298
774260
3000
adaptacija na dominirajuće okolnosti
12:57
that facilitates its future survival.
299
777260
3000
koja olakšava njegovo buduće preživljavanje.
13:00
Faced with severely limited resources,
300
780260
3000
Suočeno s veoma ograničenim resursima,
13:03
a smaller-sized child with reduced energy requirements
301
783260
3000
dijete manje veličine s reduciranim potrebama energije
13:06
will, in fact, have a better chance
302
786260
2000
će zapravo imati bolje šanse
13:08
of living to adulthood.
303
788260
2000
za život u odrasloj dobi.
13:10
The real trouble comes
304
790260
2000
Pravi problem dolazi
13:12
when pregnant women are, in a sense, unreliable narrators,
305
792260
3000
kada trudnice postanu na neki način nepouzdani pripovjedači
13:15
when fetuses are led
306
795260
2000
pa fetusi budu navedeni
13:17
to expect a world of scarcity
307
797260
2000
da očekuju svijet siromaštva,
13:19
and are born instead into a world of plenty.
308
799260
3000
a umjesto toga rode se u svijetu izobilja.
13:22
This is what happened to the children of the Dutch "Hunger Winter."
309
802260
3000
To se dogodilo djeci nizozemske „Gladne zime“.
13:25
And their higher rates of obesity,
310
805260
2000
I njihova veća razina gojaznosti,
13:27
diabetes and heart disease
311
807260
2000
dijabetes i srčane bolesti
13:29
are the result.
312
809260
2000
su rezultat.
13:31
Bodies that were built to hang onto every calorie
313
811260
3000
Tijela napravljena tako da ovise o svakoj kaloriji
13:34
found themselves swimming in the superfluous calories
314
814260
2000
našla su se plivajući u suvišku kalorija
13:36
of the post-war Western diet.
315
816260
3000
poslijeratne Zapadne dijete.
13:39
The world they had learned about while in utero
316
819260
3000
Svijet o kojem su učili dok su bili u maternici
13:42
was not the same
317
822260
2000
nije bio jednak
13:44
as the world into which they were born.
318
824260
3000
svijetu u kojem su se rodili.
13:47
Here's another story.
319
827260
2000
Evo još jedne priče.
13:49
At 8:46 a.m. on September 11th, 2001,
320
829260
4000
U 8:46, 11. rujna 2001.
13:53
there were tens of thousands of people
321
833260
2000
desetak tisuća ljudi bilo je
13:55
in the vicinity of the World Trade Center
322
835260
2000
u blizini Svjetskog trgovačkog centra
13:57
in New York --
323
837260
2000
u New Yorku –
13:59
commuters spilling off trains,
324
839260
2000
putnici izlaze iz vlakova,
14:01
waitresses setting tables for the morning rush,
325
841260
3000
konobarice postavljaju stolove za jutarnju gužvu,
14:04
brokers already working the phones on Wall Street.
326
844260
4000
brokeri već rade na telefonima na Wall Streetu.
14:08
1,700 of these people were pregnant women.
327
848260
3000
1700 do tih ljudi su bile trudnice.
14:11
When the planes struck and the towers collapsed,
328
851260
3000
Kada su se zrakoplovi zabili i tornjevi srušili,
14:14
many of these women experienced the same horrors
329
854260
3000
mnoge od tih žena doživjele su iste strahote
14:17
inflicted on other survivors of the disaster --
330
857260
3000
kao i drugi preživjeli u toj katastrofi –
14:20
the overwhelming chaos and confusion,
331
860260
2000
prevladavajući kaos i zbrka,
14:22
the rolling clouds
332
862260
2000
oblaci potencijalno
14:24
of potentially toxic dust and debris,
333
864260
4000
otrovne prašine i krhotina,
14:28
the heart-pounding fear for their lives.
334
868260
2000
lupanje srca u strahu za vlastite živote.
14:30
About a year after 9/11,
335
870260
2000
Otprilike godinu dana nakon 11.09.
14:32
researchers examined a group of women
336
872260
3000
istraživači su pregledali grupu žena
14:35
who were pregnant
337
875260
2000
koje su bile trudne
14:37
when they were exposed to the World Trade Center attack.
338
877260
2000
kada su bile izložene napadu na Svjetski trgovački centar.
14:39
In the babies of those women
339
879260
2000
Kod beba tih žena
14:41
who developed post-traumatic stress syndrome, or PTSD,
340
881260
3000
koje su razvile posttraumatski stresni poremećaj ili PTSP,
14:44
following their ordeal,
341
884260
2000
slijedeći njihovu patnju,
14:46
researchers discovered a biological marker
342
886260
3000
istraživači su otkrili biološki marker
14:49
of susceptibility to PTSD --
343
889260
2000
osjetljivosti na PTSP –
14:51
an effect that was most pronounced
344
891260
3000
efekt koji je bio najnaglašeniji
14:54
in infants whose mothers experienced the catastrophe
345
894260
3000
kod dojenčadi čije su majke doživjele katastrofu
14:57
in their third trimester.
346
897260
2000
u njihovom trećem tromjesečju.
14:59
In other words,
347
899260
2000
Drugim riječima,
15:01
the mothers with post-traumatic stress syndrome
348
901260
3000
majke s posttraumatskim stresnim poremećajem
15:04
had passed on a vulnerability to the condition
349
904260
3000
su prenijele ranjivost
15:07
to their children while they were still in utero.
350
907260
3000
na svoju djecu dok su još bila u maternici.
15:10
Now consider this:
351
910260
2000
Uzmite u obzir,
15:12
post-traumatic stress syndrome
352
912260
2000
posttraumatski stresni poremećaj
15:14
appears to be a reaction to stress gone very wrong,
353
914260
3000
je reakcija na stres koji je pošao veoma krivo,
15:17
causing its victims tremendous unnecessary suffering.
354
917260
4000
uzrokujući svojim žrtvama ogromnu, nepotrebnu patnju.
15:21
But there's another way of thinking about PTSD.
355
921260
3000
Ali postoji i drugi način razmišljanja o PTSP-u.
15:24
What looks like pathology to us
356
924260
3000
Ono što nama izgleda kao patologija
15:27
may actually be a useful adaptation
357
927260
2000
može biti korisna adaptacija
15:29
in some circumstances.
358
929260
2000
u nekim okolnostima.
15:31
In a particularly dangerous environment,
359
931260
3000
U naročito opasnim okolinama,
15:34
the characteristic manifestations of PTSD --
360
934260
3000
karakteristične manifestacije PTSP-a –
15:37
a hyper-awareness of one's surroundings,
361
937260
3000
hipersvjesnost okruženja,
15:40
a quick-trigger response to danger --
362
940260
3000
brzi okidač na opasnost,
15:43
could save someone's life.
363
943260
3000
može spasiti nečiji život.
15:46
The notion that the prenatal transmission of PTSD risk is adaptive
364
946260
4000
Ideja o prenatalnom prijenosu PTSP rizika je prilagodljiva,
15:50
is still speculative,
365
950260
2000
još je spekulativna,
15:52
but I find it rather poignant.
366
952260
3000
ali ja je smatram pronicljivom.
15:55
It would mean that, even before birth,
367
955260
2000
To bi značilo da čak prije rođenja
15:57
mothers are warning their children
368
957260
2000
majke upozoravaju svoju djecu
15:59
that it's a wild world out there,
369
959260
2000
da je tamo vani divlji svijet,
16:01
telling them, "Be careful."
370
961260
3000
govoreći im: „Budite oprezni.“
16:04
Let me be clear.
371
964260
2000
Da budem jasna,
16:06
Fetal origins research is not about blaming women
372
966260
3000
istraživanje fetalnog podrijetla nije u okrivljavanju žena
16:09
for what happens during pregnancy.
373
969260
2000
za ono što se događa tijekom trudnoće.
16:11
It's about discovering how best to promote
374
971260
3000
Cilj je otkriti kako najbolje poboljšati
16:14
the health and well-being of the next generation.
375
974260
3000
zdravlje i blagostanje sljedećih generacija.
16:17
That important effort must include a focus
376
977260
2000
Taj važan napor mora se usmjeriti
16:19
on what fetuses learn
377
979260
2000
na ono što fetusi uče
16:21
during the nine months they spend in the womb.
378
981260
3000
tijekom devet mjeseci koje provedu u maternici.
16:24
Learning is one of life's most essential activities,
379
984260
3000
Učenje je jedna od najvažnijih aktivnosti u životu
16:27
and it begins much earlier
380
987260
2000
i počinje mnogo ranije
16:29
than we ever imagined.
381
989260
2000
nego što smo ikada zamišljali.
16:31
Thank you.
382
991260
2000
Hvala vam.
16:33
