¿Hablas español? Parlez-vous français? 你会说中文吗?
00:12
If you answered, "sí," "oui," or "会" and you're watching this in English,
1

Agar siz "si", "oui" yoki "是的" deb javob bergan bo'lsangiz va siz buni inglizchada
00:18
chances are you belong to the world's bilingual and multilingual majority.

ko'rayotgan bo'lsangiz, siz ko'pchilik bilinguallar va poliglotlar qatoridasiz.
00:23
And besides having an easier time traveling

Siz sayohat qilish oson bo'lishi yoki filmlarni
00:25
or watching movies without subtitles,

1908
subtitrsiz ko'ra olishdan tashqari,
00:27
knowing two or more languages means that your brain
5
27471
2424
ikki yoki undan ko'proq tilni bilishingiz miyangizning
00:29
may actually look and work differently than those of your monolingual friends.
6

4882
o'zgacha ishlashi va monolingual do'stlar- ingizga nisbatan farq qilishini bildiradi.
00:34
So what does it really mean to know a language?
7
34777

Xo'sh, "tilni egallsh" degani aslida nimani anglatadi?
00:38
Language ability is typically measured in two active parts, speaking and writing,
8
38272
4861
Tilni bilishni odatda ikkita belgiga ko'ra baholashadi: og'zaki va
yozma, va ikkita passiv belgilar: nutqni
00:43
and two passive parts, listening and reading.

eshitib tushunish va o'qib tushunish. Balansga ega bilingual
00:46
While a balanced bilingual has near equal
10
46985
2670
insonda yuqoridagi ko'rsatkichlari
00:49
abilities across the board in two languages,
11
49655
2722
ikki tilda ham bir xil bo'ladi.
00:52
most bilinguals around the world know and use their languages
12
52377
3383
Lekin dunyoda ikkita tilni teng bo'lmagan proporsiyalarda
00:55
in varying proportions.
13
55760
2221
ishlatadigan va biladigan bilinguallar ko'proq.
00:57
And depending on their situation and how they acquired each language,
14
57981
3631
Tilni egallash sharoyitiga qarab
01:01
they can be classified into three general types.
15
61612
3303
bilinguallarni uch turga ajratish mumkin.
01:04
For example, let's take Gabriella,
16
64915
2852
Masalan, Gabrielladan boshlasak,
01:07
whose family immigrates to the US from Peru when she's two-years old.
17
67767
4240
Uning oilasi AQSHdan Peruga ko'chganida u ikki yoshda edi.
01:12
As a compound bilingual,
18
72007
1816
Gabriella — haqiqiy bilingual,
01:13
Gabriella develops two linguistic codes simultaneously,
19
73823
4452
ya'ni u bir vaqtning o'zida ikkita tilni o'zlashtiradi
01:18
with a single set of concepts,
20
78275
2022
Tushunchalarni bir xil o'zlashtirib boradi.
01:20
learning both English and Spanish
21
80297
1868
U ham ispancha, ham inglizcha o'rganadi,
01:22
as she begins to process the world around her.
22
82165
3193
dunyoni endi-endi o'rganish davomida.
01:25
Her teenage brother, on the other hand, might be a coordinate bilingual,
23
85358
3804
Uning akasi esa, o'smir bo'lgani uchun
aralash bilingual bo'lib ulg'ayadi.
01:29
working with two sets of concepts,
24
89162
2176
Ular ongida ikki xil tushunchalar mavjud,
01:31
learning English in school,
25
91338
1862
ya'ni ingliz tilidan maktabda foydalansa,
01:33
while continuing to speak Spanish at home and with friends.
26
93200
3564
uyda va o'rtoqlari bilan ispan tilida gaplashadi.
01:36
Finally, Gabriella's parents are likely to be subordinate bilinguals
27
96764
5081
Uning ota-onalarida esa, subordinativ bilingvizm shakllanadi, ya'ni ular
01:41
who learn a secondary language
28
101845
1565
chet tilini o'z ona tili orqali,
01:43
by filtering it through their primary language.
29
103410
2788
solishtirib o'rganishgan.
01:46
Because all types of bilingual people can become fully proficient in a language
30
106198
4017
Barcha tipdagi bilingualla ham tilni egallashi mumkin.
01:50
regardless of accent or pronunciation,
31
110215
2508
Va talaffuzi, urg'ularining farqlanishiga qaramay,
01:52
the difference may not be apparent to a casual observer.
32
112723
3120
tinglovchi bilinguallarni turi bo'yicha ajratib olishi qiyin.
01:55
But recent advances in brain imaging technology
33
115843
2776
Neyrovizualizatsiyaning so'nggi yutuqlari shundan iboratki,
01:58
have given neurolinguists a glimpse
34
118619
2240
til o'rganishning ayrim aspektlari
02:00
into how specific aspects of language learning affect the bilingual brain.
35
120859
4855
bilingualning miyasiga ham ta'sir qilar ekan.
02:05
It's well known that the brain's left hemisphere is more dominant
36
125714
3295
Hammaga ma'lumki, mantiqiy jarayonlarda
02:09
and analytical in logical processes,
37
129009
2613
miyaning chap yarimshari ko'proq aktiv bo'ladi.
02:11
while the right hemisphere is more active in emotional and social ones,
38
131622
4580
O'ng yarimshar esa his-tuyg'ular yoki sotsial jarayonlarda
02:16
though this is a matter of degree, not an absolute split.
39
136202
3873
ko'proq aktiv holatda bo'ladi.
02:20
The fact that language involves both types of functions
40
140075
2808
Til esa bu ikki xil jarayonga ham tegishli hisoblanib,
02:22
while lateralization develops gradually with age,
41
142883
2978
yarimsharlararo assimetriya yil sayin rivojlanishi
02:25
has lead to the critical period hypothesis.
42
145861
2938
olimlarni senzitiv period gipotezasiga olib keldi.
02:28
According to this theory,
43
148799
1631
Gipotezaga ko'ra, bolalar tillarni
02:30
children learn languages more easily
44
150430
1976
oson o'rganishadi, ularning endi
02:32
because the plasticity of their developing brains
45
152406
2790
rivojlanayotgan miyasi egiluvchan bo'lganligi til o'rganish
02:35
lets them use both hemispheres in language acquisition,
46
155196
3779
jarayonida miyaning ikkita yarimsharini ham harakatga keltiradi.
02:38
while in most adults, language is lateralized to one hemisphere,
47
158975
4017
Ko'pchilik kattalarda esa yarimsharlararo assimetriya
02:42
usually the left.
48
162992
1906
chap yarimsharni aktivlashtiradi.
02:44
If this is true, learning a language in childhood
49
164898
2786
Agar gipoteza rost bo'lsa, bolalikda til o'rganish
02:47
may give you a more holistic grasp of its social and emotional contexts.
50
167684
4796
sizga emotsional va sotsial tagma'nolarni to'liq tushunishga yordam beradi.
02:52
Conversely, recent research showed
51
172480
2330
Yaqindagi tadqiqotlar shuni ko'rsatdiki,
02:54
that people who learned a second language in adulthood
52
174810
2710
chet tillarini o'rgangan insonlar katta yoshda
02:57
exhibit less emotional bias and a more rational approach
53
177520
3903
ona tili hisoblanmagan,
boshqa tillarni qo'llashda his-tuyg'ularga
03:01
when confronting problems in the second language
54
181423
2388
kamroq moyil bo'lib, bu tilga oqilona
03:03
than in their native one.
55
183811
1649
yondashuvni namoyon etishadi.
03:05
But regardless of when you acquire additional languages,
56
185460
2649
Chet tilini qachon o'rganishingizni farqi yo'q,
03:08
being multilingual gives your brain some remarkable advantages.
57
188109
4101
ko'ptillilik sizning miyangiz ish faoliyatiga ko'p foyda beradi.
03:12
Some of these are even visible,
58
192210
1544
Ba'zilarini ko'rishimiz ham
03:13
such as higher density of the grey matter
59
193754
2584
mumkin, masalan, kulrang moddaning zichligi, unda
03:16
that contains most of your brain's neurons and synapses,
60
196338
3103
miyamizdagi neyronlarning va sinapslarning ko'p qismi joylashgan.
03:19
and more activity in certain regions when engaging a second language.
61
199441
4063
Undan tashqari, til o'rganish jarayonida miyaning alohida
qismlarida faollik kuzatish
03:23
The heightened workout a bilingual brain receives throughout its life
62
203504
3385
mumkin. Bilinguallar butun umr
shug'ullanadigan intensiv til o'rganish mashg'ulotlari
03:26
can also help delay the onset of diseases, like Alzheimer's and dementia
63
206889
4445
alsgeymer, dimensiya kabi kasalliklarining kelishini o'rtacha
03:31
by as much as five years.
64
211334
1891
besh yilga cho'zishi mumkin.
03:33
The idea of major cognitive benefits to bilingualism
65
213225
2718
Bilingvizmning kognitiv foydasi haqidagi g'oyalar hozirda
03:35
may seem intuitive now,
66
215943
1576
tushunarli ko'rinadi, lekin bu kabi g'oyalar
03:37
but it would have surprised earlier experts.
67
217519
2988
o'tmish olimlarini hayratga solgan bo'lardi.
03:40
Before the 1960s, bilingualism was considered a handicap
68
220507
3687
1960-yillargacha bilinguallik bu noqulaylik deb hisoblangan, u bolaning
03:44
that slowed a child's development
69
224194
1805
rivojlanishini pasaytirgan va tillarni
03:45
by forcing them to spend too much energy distinguishing between languages,
70
225999
4653
ajratish uchun boladan ko'p vaqt
oladi deb hisoblangan. Bunaqa qarashlar
03:50
a view based largely on flawed studies.
71
230652
3437
o'sha vaqtlarda olib borilgan noto'g'ri tadqiqotlar natijasi edi. Keyinchalik
03:54
And while a more recent study did show
72
234089
2089
olib borilgan tadqiqotlar bilingual
03:56
that reaction times and errors increase for some bilingual students
73
236178
3237
talabalar nazorat ishlari yoki imtihonlarda masalalarni ishlashda
03:59
in cross-language tests,
74
239415
2012
ko'proq vaqt sarflashi isbotlansa-da, undan
04:01
it also showed that the effort and attention needed
75
241427
2398
tashqari, bir tildan ikkinchi tilga o'tishda yuzaga
04:03
to switch between languages triggered more activity in,
76
243825
2951
keladigan keskinlik va diqqat katta faollik talab qiladi,
04:06
and potentially strengthened, the dorsolateral prefrontal cortex.
77
246776
4689
miyaning dorsolateral va prefrontal zonasini mustahkamlaydi.
04:11
This is the part of the brain that plays a large role
78
251465
2677
Miyaning bu qismi asosan,
04:14
in executive function, problem solving, switching between tasks,
79
254142
4829
tashkiliy funksiyalar, muammolarni yechish, vazifadan vazifaga o'tish,
04:18
and focusing while filtering out irrelevant information.
80
258971
3673
va shuningdek, keraksiz ma'lumotlarni olib tashlashga hizmat qiladi.
04:22
So, while bilingualism may not necessarily make you smarter,
81
262644
3836
Bilingvizm sizni aqlliroq qilishi aniq emas, lekin u sizning miyangizni
04:26
it does make your brain more healthy, complex and actively engaged,
82
266480
4417
yanada sog'lom va murakkab qiladi
va uning imkoniyatlarini kengaytiradi.
04:30
and even if you didn't have the good fortune
83
270897
2525
Va garchi bolalikda sizga chet tillarini o'rganish
04:33
of learning a second language as a child,
84
273422
2229
nasib qilmagan bo'lsa-da,
04:35
it's never too late to do yourself a favor
85
275651
2143
o'zingiz uchun "Salom" dan "Hola", "Bonjour"
04:37
and make the linguistic leap from, "Hello,"
86
277794
2778
yoki "您好" ga lingvistik sakrash qilish uchun
04:40
to, "Hola," "Bonjour" or "你好’s"
87
280572
2987
hech qachon kech emas.
04:43
because when it comes to our brains a little exercise can go a long way.
88
283559
4522
Zero, bu miyamiz bilan bog'liq ekan,
hatto kichik qadam ham katta bir safarning boshi bo'lishi mumkin.
