Da li deca loše lažu? Da li mislite da lako možete da otkrijete njihove laži? Razvojni istraživač Kang Lee proučava šta se dešava sa njihovom fiziologijom kada deca lažu. Oni to rade često, počinju rano kao dvogodišnjaci, i zapravo su veoma dobri u tome. Lee objašnjava zašto bi trebali slaviti kada deca počnu da lažu i predstavlja novu tehnologiju za detektovanje laži, koja bi mogla jednog dana otkriti naše skrivene emocije.

Ćao.
00:14
Let me ask the audience a question:
1
2461
2346
Pitanje za publiku:
00:16
Did you ever lie as a child?
2
4831
2195
Da li ste lagali kad ste bili dete?
00:19
If you did, could you please
raise your hand?
raise your hand?

Ako jeste, molim vas podignite ruku.
00:23
Wow! This is the most honest
group of people I've ever met.

11145

Vau! Ovo je najiskrenija grupa ljudi
koju sam ikada sreo.
koju sam ikada sreo.
00:26
(Laughter)
5
14623
1957
(Smeh)
00:28
So for the last 20 years,
6
16604
1709
Poslednjih 20 godina sam,
00:30
I've been studying
how children learn to tell lies.
how children learn to tell lies.
7
18337
3415
proučavao kako deca uče da lažu.
00:33
And today, I'm going to share with you
8
21776
2304
I danas ću podeliti sa vama
00:36
some of the discoveries we have made.
9
24104
2162
neka od saznanja koja smo otkrili.
00:38
But to begin, I'm going to tell you
a story from Mr. Richard Messina,
a story from Mr. Richard Messina,
10
26624
4925
Ali za početak, ispričaću vam priču
gospodina Ričarda Mesina,
gospodina Ričarda Mesina,
00:43
who is my friend and an elementary
school principal.
school principal.
11
31573
3129
koji je moj prijatelj i direktor
u jednoj osnovnoj školi.
u jednoj osnovnoj školi.
00:47
He got a phone call one day.
12
35266
1561
Jednom je primio poziv telefonom
00:51
The caller says,
13
39279
1151
Pozivatelj je rekao,
00:52
"Mr. Messina, my son Johnny
will not come to school today
will not come to school today
14
40454
3882
"G. Mesina, moj sin Džoni neće doći
u školu danas
u školu danas
00:56
because he's sick."
15
44360
1463
zato što je bolestan."
00:58
Mr. Messina asks,
16
46498
1736
G. Messina pita,
01:00
"Who am I speaking to, please?"
17
48258
2014
"Molim vas, recite ko je to."
01:02
And the caller says,
18
50788
1490
A pozivatelj kaže,
01:04
"I am my father."
19
52302
1665
"Ja sam moj otac."
01:05
(Laughter)
20
53991
2787
(Smeh)
01:10
So this story --
21
58227
1682
Tako ova priča --
01:11
(Laughter)
22
59933
1532
(Smeh)
01:13
sums up very nicely
three common beliefs we have
three common beliefs we have
23
61489
4310
sumira veoma lepo
tri česta ubeđenja koja imamo
tri česta ubeđenja koja imamo
01:17
about children and lying.
24
65823
1859
o deci i laganju.
01:20
One, children only come to tell lies
25
68140
4631
Jedan, deca lažu samo
01:24
after entering elementary school.
26
72795
2268
nakon što pođu u osnovnu školu.
01:27
Two, children are poor liars.
27
75552
2311
Dva, deca loše lažu.
01:29
We adults can easily detect their lies.
28
77887
2857
Mi odrasli možemo lako otkriti
njihove laži.
njihove laži.
01:32
And three, if children lie
at a very young age,
at a very young age,
29
80768
4038
I tri, ako deca lažu
od malih nogu,
od malih nogu,
01:36
there must be some
character flaws with them,
character flaws with them,
30
84830
2849
mora da imaju neku
karakternu manu,
karakternu manu,
01:39
and they are going to become
pathological liars for life.
pathological liars for life.
31
87703
4049
i postaće patološki lažovi
kad odrastu.
kad odrastu.
01:44
Well, it turns out
32
92720
2194
Pa, ispada da
01:46
all of the three beliefs are wrong.
33
94938
2298
sva tri navedena ubeđenja su pogrešna.
01:50
We have been playing guessing games
34
98617
2710
Igrali smo igre pogađanja
01:53
with children all over the world.
35
101351
2082
sa decom širom sveta.
01:55
Here is an example.
36
103457
1486
Na primer,
01:56
So in this game, we asked children
to guess the numbers on the cards.
to guess the numbers on the cards.
37
104967
4365
U ovoj igri pitali smo decu
da pogode brojeve na kartama.
da pogode brojeve na kartama.
02:01
And we tell them if they win the game,
38
109958
2878
I kada im kažemo da ako pobede,
02:04
they are going to get a big prize.
39
112860
2157
dobiće veliku nagradu.
02:07
But in the middle of the game,
40
115525
1477
Ali u sred igre,
02:09
we make an excuse and leave the room.
41
117026
2760
pod nekim izgovorom napustimo sobu.
02:13
And before we leave the room,
42
121763
1934
I pre nego što odemo,
02:15
we tell them not to peek at the cards.
43
123721
2936
kažemo im da ne vire u karte.
02:19
Of course,
44
127518
1416
Naravno,
02:20
we have hidden cameras in the room
45
128958
2161
mi imamo skrivene kamere u sobi
02:23
to watch their every move.
46
131143
1795
i posmatramo svaki njihov pokret.
02:26
Because the desire
to win the game is so strong,
to win the game is so strong,
47
134216
3417
Pošto je želja za pobedom
u igri tako jaka,
u igri tako jaka,
02:29
more than 90 percent of children will peek
48
137657
3486
više od 90 procenata dece će viriti
02:33
as soon as we leave the room.
49
141167
1437
čim napustimo sobu.
02:34
(Laughter)
50
142628
2000
(smeh)
02:37
The crucial question is:
51
145044
1986
Osnovno pitanje je:
02:39
When we return and ask the children
52
147054
2748
Kada se vratimo i pitamo decu
02:41
whether or not they have peeked,
53
149826
2309
da li su ili nisu virili,
02:44
will the children who peeked confess
54
152159
3052
da li će deca koja su virila priznati
02:47
or lie about their transgression?
55
155235
2578
ili lagati o svom prestupu.
02:51
We found that regardless
of gender, country, religion,
of gender, country, religion,
56
159525
4773
Saznali smo da bez obzira na pol,
zemlju, religiju,
zemlju, religiju,
02:56
at two years of age,
57
164934
1579
sa dve godine starosti
02:59
30 percent lie,
58
167188
1927
30 posto laže,
03:01
70 percent tell the truth
about their transgression.
about their transgression.
59
169139
3809
70 posto kaže istinu o svom prestupu.
03:04
At three years of age,
60
172972
2138
Sa tri godine starosti
03:07
50 percent lie and 50 percent
tell the truth.
tell the truth.
61
175134
3474
50 posto laže, 50 posto kaže istinu.
03:11
At four years of age,
62
179302
1899
Sa četiri godine,
03:13
more than 80 percent lie.
63
181225
1947
više od 80 posto laže.
03:16
And after four years of age,
64
184334
2451
A posle četiri pune godine,
03:18
most children lie.
65
186809
1389
većina dece laže.
03:21
So as you can see,
66
189180
1363
Tako da kao što vidite,
03:22
lying is really a typical part
of development.
of development.
67
190567
3463
laganje je tipičan deo
razvoja.
razvoja.
03:26
And some children begin to tell lies
68
194054
2790
I neka deca počinju da lažu
03:28
as young as two years of age.
69
196868
2439
već sa dve godine života.
03:32
So now, let's take a closer look
at the younger children.
at the younger children.
70
200438
3557
Ajde sada da pogledamo izbliza mlađu decu.
03:37
Why do some but not all
young children lie?
young children lie?
71
205336
3813
Zašto neka, ali ne sva, mala deca lažu?
03:42
In cooking, you need good ingredients
72
210184
3329
Prilikom kuvanja,
trebaju vam dobri sastojci
trebaju vam dobri sastojci
03:45
to cook good food.
73
213537
1613
da biste napravili dobru hranu.
03:47
And good lying requires
two key ingredients.
two key ingredients.
74
215793
4563
A dobro laganje zahteva
dva ključna sastojka.
dva ključna sastojka.
03:53
The first key ingredient
is theory of mind,
is theory of mind,
75
221109
4110
Prvi ključni sastojak je
teorija uma,
teorija uma,
03:57
or the mind-reading ability.
76
225243
1835
ili sposobnost čitanja misli.
03:59
Mind reading is the ability to know
77
227768
2078
To jest sposobnost znati
04:01
that different people have
different knowledge about the situation
different knowledge about the situation
78
229870
4608
da različiti ljudi imaju različito
znanje o istoj situaciji
znanje o istoj situaciji
04:06
and the ability to differentiate
between what I know
between what I know
79
234502
3801
i sposobnost da razlikujete
ono što ja znam
ono što ja znam
04:10
and what you know.
80
238327
1223
od onoga što vi znate.
04:11
Mind reading is important for lying
81
239914
2247
Čitanje misli je važno za laganje
04:14
because the basis of lying is that I know
82
242185
3847
zato što je osnova laganja da ja znam
04:18
you don't know
83
246056
1151
da ti ne znaš
04:19
what I know.
84
247231
1151
da ja znam.
04:20
Therefore, I can lie to you.
85
248406
1371
Znači ja mogu da te slažem.
04:23
The second key ingredient
for good lying is self-control.
for good lying is self-control.
86
251070
4610
Drugi glavni sastojak za dobro laganje
samokontrola.
samokontrola.
04:27
It is the ability to control your speech,
your facial expression
your facial expression
87
255704
4623
To je sposobnost da kontrolišete govor,
facijalnu ekspresiju
facijalnu ekspresiju
04:32
and your body language,
88
260351
1540
i govor tela,
04:33
so that you can tell a convincing lie.
89
261915
2078
tako da možete da kažete uverljivu laž.
04:36
And we found that those young children
90
264938
3726
I saznali smo da mlada djeca
04:40
who have more advanced mind-reading
and self-control abilities
and self-control abilities
91
268688
4856
koja imaju bolju sposobnost čitanja misli
i samokontrole
i samokontrole
04:45
tell lies earlier
92
273568
2038
počinju da lažu ranije
04:47
and are more sophisticated liars.
93
275630
2816
i mnogo su sofisticiraniji u laganju.
04:51
As it turns out, these two abilities
are also essential for all of us
are also essential for all of us
94
279887
5619
I kako izgleda, ove dvije sposobnosti
su također esencijalne za sve nas
su također esencijalne za sve nas
04:57
to function well in our society.
95
285530
2522
za dobro funkcionisanje u našem društvu.
05:00
In fact, deficits in mind-reading
and self-control abilities
and self-control abilities
96
288848
4335
Zapravo, deficit u sposobnosti čitanja
misli i samokontrole
misli i samokontrole
05:05
are associated with serious
developmental problems,
developmental problems,
97
293207
3559
su povezani sa ozbiljnim
razvojnim problemima,
razvojnim problemima,
05:08
such as ADHD and autism.
98
296790
2759
kao što su ADHD i autizam.
05:13
So if you discover your two-year-old
is telling his or her first lie,
is telling his or her first lie,
99
301893
5177
Tako da ako otkrijete da vaš dvogodišnjak
govori svoju prvu laž,
govori svoju prvu laž,
05:19
instead of being alarmed,
100
307094
1984
umjesto da budete zabrinuti,
05:21
you should celebrate --
101
309102
1492
trebali biste slaviti.
05:22
(Laughter)
102
310618
1522
(smjeh)
05:24
because it signals that your child
has arrived at a new milestone
has arrived at a new milestone
103
312164
5730
zato što to znači da je vaše dijete
postiglo stupanj
postiglo stupanj
05:29
of typical development.
104
317918
1635
tipičnog razvoja.
05:33
Now, are children poor liars?
105
321085
3136
Sada, da li djeca loše lažu?
05:36
Do you think you can easily
detect their lies?
detect their lies?
106
324878
2994
Da li mislite da možete lako
da otkrijete njihove laži?
da otkrijete njihove laži?
05:40
Would you like to give it a try?
107
328745
1678
Da li biste željeli da probate?
05:42
Yes? OK.
108
330921
1480
Da? U redu.
05:44
So I'm going to show you two videos.
109
332425
2139
Pokazaću vam dva snimka.
05:47
In the videos,
110
335024
1151
U snimcima,
05:48
the children are going to respond
to a researcher's question,
to a researcher's question,
111
336199
3057
djeca će odgovoriti na
istraživačevo pitanje,
istraživačevo pitanje,
05:51
"Did you peek?"
112
339280
1482
"Da li si virio?"
05:52
So try to tell me
113
340786
1554
Pokušajte mi reći
05:54
which child is lying
114
342364
1398
koje dijete laže
05:55
and which child is telling the truth.
115
343786
2110
a koje govori istinu.
05:58
Here's child number one.
116
346272
1719
Ovo je dijete broj jedan.
06:00
Are you ready?
117
348991
1237
Da li ste spremni?
06:03
(Video) Adult: Did you peek? Child: No.
118
351006
1920
Odrasli: Da li si virio?
Dijete: Ne
Dijete: Ne
06:05
Kang Lee: And this is child number two.
119
353619
2236
Kang Lee: Ovo je dijete broj 2.
06:09
(Video) Adult: Did you peek? Child: No.
120
357501
2192
Odrasli: Da li si virio? Dijete: Ne.
06:13
KL: OK, if you think
child number one is lying,
child number one is lying,
121
361296
3587
U redu, ako mislite
da dijete broj 1 laže,
da dijete broj 1 laže,
06:16
please raise your hand.
122
364907
1687
molim vas podignite ruku.
06:20
And if you think child number two
is lying, please raise your hand.
is lying, please raise your hand.
123
368401
3552
A ako mislite da dijete broj 2
laže, molim vas podignite ruku.
laže, molim vas podignite ruku.
06:25
OK, so as a matter of fact,
124
373593
2474
U redu, činjenica je da
06:28
child number one is telling the truth,
125
376091
2937
dijete broj 1 govori istinu,
06:31
child number two is lying.
126
379052
2029
dijete broj 2 laže.
06:34
Looks like many of you are terrible
detectors of children's lies.
detectors of children's lies.
127
382124
3230
Izgleda da su mnogi od vas
loši detektori dječjih laži.
loši detektori dječjih laži.
06:37
(Laughter)
128
385378
2478
(Smjeh)
06:39
Now, we have played similar kinds of games
129
387880
3384
Igrali smo sličnu vrstu igara
06:43
with many, many adults
from all walks of life.
from all walks of life.
130
391288
4625
sa mnogo, mnogo odraslih
iz svih životnih pozicija.
iz svih životnih pozicija.
06:48
And we show them many videos.
131
396714
2158
I pokazali smo im mnoge snimke.
06:51
In half of the videos, the children lied.
132
399347
2549
U polovini snimaka djeca su lagala.
06:53
In the other half of the videos,
the children told the truth.
the children told the truth.
133
401920
3267
U drugoj polovini snimaka
djeca su govorila istinu.
djeca su govorila istinu.
06:58
And let's find out
how these adults performed.
how these adults performed.
134
406529
2857
Da vidimo kako su se odrasli prošli.
07:02
Because there are as many liars
as truth tellers,
as truth tellers,
135
410319
3855
Pošto ima jednak broj onih koji lažu
i onih koji govore istinu,
i onih koji govore istinu,
07:06
if you guess randomly,
136
414198
2399
ako pogađate nasumice,
07:08
there's a 50 percent chance
you're going to get it right.
you're going to get it right.
137
416621
4070
imate 50 procenata šanse
da ćete pogoditi.
da ćete pogoditi.
07:12
So if your accuracy is around 50 percent,
138
420715
3594
Tako da ako je vaša tačnost oko 50
procenata,
procenata,
07:16
it means you are a terrible detector
of children's lies.
of children's lies.
139
424333
3441
to znači da ste loš detektor
dječjih laži.
dječjih laži.
07:20
So let's start with undergrads
and law school students,
and law school students,
140
428290
4529
Pa počnimo od diplomaca i studenata prava,
07:24
who typically have
limited experience with children.
limited experience with children.
141
432843
3672
koji tipično imaju
ograničena iskustva sa djecom.
ograničena iskustva sa djecom.
07:30
No, they cannot detect children's lies.
142
438038
1962
Oni ne mogu da otkriju kada dječje laži.
07:32
Their performance is around chance.
143
440024
2214
Njihov učinak je oko slučajnog.
07:34
Now how about social workers
and child-protection lawyers,
and child-protection lawyers,
144
442262
5229
A socijalni radnici,
i advokati dječjih prava,
i advokati dječjih prava,
07:39
who work with children on a daily basis?
145
447515
2674
koji rade sa djecom svakodnevno?
07:42
Can they detect children's lies?
146
450213
2087
Mogu li oni otkriti dječje laži?
07:45
No, they cannot.
147
453624
1151
Ne, ne mogu.
07:46
(Laughter)
148
454799
1045
(Smjeh)
07:47
What about judges,
149
455868
1472
A sudije,
07:49
customs officers
150
457364
1800
carinici
07:51
and police officers,
151
459188
1858
i policajci,
07:53
who deal with liars on a daily basis?
152
461070
2643
koji se bave ljudima koji lažu
svakoga dana?
svakoga dana?
07:55
Can they detect children's lies?
153
463737
1917
Mogu li oni otkriti dječje laži?
07:58
No, they cannot.
154
466800
1214
Ne, ne mogu.
08:00
What about parents?
155
468430
1186
A roditelji?
08:01
Can parents detect other children's lies?
156
469640
3014
Mogu li roditelji otkriti lađi tuđe djece?
08:05
No, they cannot.
157
473898
1238
Ne, ne mogu.
08:07
What about, can parents
detect their own children's lies?
detect their own children's lies?
158
475821
3585
A mogu li roditelji otkriti laži
svoje sopstvene djece?
svoje sopstvene djece?
08:13
No, they cannot.
159
481208
1201
Ne, ne mogu.
08:14
(Laughter) (Applause)
160
482433
3476
(Smjeh) (Aplauz)
08:17
So now you may ask
161
485933
1547
Sada možete pitati
08:20
why children's lies
are so difficult to detect.
are so difficult to detect.
162
488504
3632
zašto su dječje laži tako teške
za otkriti.
za otkriti.
08:24
Let me illustrate this
with my own son, Nathan.
with my own son, Nathan.
163
492958
3012
Da navedem primer moga sina Nejtana.
08:27
This is his facial expression
164
495994
2169
Ovo je njegov izraz lica
08:30
when he lies.
165
498187
1384
kada laže.
08:31
(Laughter)
166
499595
2206
(Smjeh)
08:33
So when children lie,
167
501825
1602
Kada djeca lažu,
08:35
their facial expression
is typically neutral.
is typically neutral.
168
503451
3156
njihov izraz lica je obično neutralan.
08:39
However, behind this neutral expression,
169
507123
3460
Ali, iza ovog neutralnog izraza lica,
08:42
the child is actually experiencing
a lot of emotions,
a lot of emotions,
170
510607
3326
dijete zapravo doživljava mnogo emocija,
08:45
such as fear, guilt, shame
171
513957
3855
kao strah, krivnja, stid
08:49
and maybe a little bit of liar's delight.
172
517836
3096
i možda malo lažovskog uzbuđenja.
08:52
(Laughter)
173
520956
2702
(Smjeh)
08:55
Unfortunately, such emotions
are either fleeting or hidden.
are either fleeting or hidden.
174
523682
4840
Nažalost, takve emocije su ili
kratkotrajne ili skrivene.
kratkotrajne ili skrivene.
09:00
Therefore, it's mostly invisible to us.
175
528546
3099
Tako da su uglavnom neprimjetne za nas.
09:03
So in the last five years,
176
531669
1359
Tako u poslednjih 5 godina,
09:05
we have been trying to figure out a way
to reveal these hidden emotions.
to reveal these hidden emotions.
177
533052
3896
pokušavali smo naći načina da otkrijemo
te skrivene emocije.
te skrivene emocije.
09:08
Then we made a discovery.
178
536972
1514
Zatim smo otkrili.
09:11
We know that underneath our facial skin,
179
539273
3185
Znamo da ispod kože našeg lica,
09:14
there's a rich network of blood vessels.
180
542482
3394
postoji bogata mreža krvnih sudova.
09:17
When we experience different emotions,
181
545900
2417
Kada iskusimo različite emocije,
09:20
our facial blood flow changes subtly.
182
548341
2641
protok krvi u našem licu se blago mijenja.
09:23
And these changes are regulated
by the autonomic system
by the autonomic system
183
551613
3948
Ove promjene su regulirane od strane
autonomnog sistema
autonomnog sistema
09:27
that is beyond our conscious control.
184
555585
2169
koji je izvan naše svjesne kontrole.
09:30
By looking at facial blood flow changes,
185
558159
3823
Promatranjem promena protoka krvi
u licu
u licu
09:34
we can reveal people's hidden emotions.
186
562006
2697
možemo otkriti ljudske skrivene emocije.
09:37
Unfortunately, such emotion-related
facial blood flow changes
facial blood flow changes
187
565229
4778
Na žalost, takve promjene
u protoku krvi u licu
u protoku krvi u licu
09:42
are too subtle to detect by our naked eye.
188
570031
2625
su suviše suptilne da se detektuju
golim okom.
golim okom.
09:45
So to help us reveal
people's facial emotions,
people's facial emotions,
189
573632
3768
Tako da bi otkrili
ljudske emocije na licu,
ljudske emocije na licu,
09:49
we have developed a new imaging technology
190
577424
3034
razvili smo novu tehnologiju snimanja
09:52
we call "transdermal optical imaging."
191
580482
3149
koju zovemo "transdermalno optičko
snimanje"
snimanje"
09:56
To do so, we use a regular
video camera to record people
video camera to record people
192
584679
3953
Da bismo to uradili koristimo običnu
video kameru da snimimo ljude
video kameru da snimimo ljude
10:00
when they experience
various hidden emotions.
various hidden emotions.
193
588656
3086
kada doživljavaju različite skrivene
emocije.
emocije.
10:04
And then, using our image
processing technology,
processing technology,
194
592385
4094
I onda koristeći našu tehnologiju
procesuiranja slike,
procesuiranja slike,
10:08
we can extract transdermal images
of facial blood flow changes.
of facial blood flow changes.
195
596503
5536
možemo da ekstrahujemo transdermalne slike
promena protoka krvi u licu.
promena protoka krvi u licu.
10:16
By looking at transdermal video images,
196
604475
4272
Gledajući u transdermalne video slike,
10:20
now we can easily see
197
608771
1787
sada možemo lako videti
10:23
facial blood flow changes associated
with the various hidden emotions.
with the various hidden emotions.
198
611737
5631
promjene u protoku krvi u licu
asocirane sa raznim skrivenim emocijama.
asocirane sa raznim skrivenim emocijama.
10:29
And using this technology,
199
617944
1788
I koristeći ovu tehnlogiju,
10:31
we can now reveal the hidden emotions
associated with lying,
associated with lying,
200
619756
4668
možemo otkriti skrivene emocije
povezane sa laganjem,
povezane sa laganjem,
10:36
and therefore detect people's lies.
201
624448
2910
i tako detektovati kada ljudi lažu.
10:39
We can do so noninvasively,
202
627382
2439
Možemo to učiniti neinvazivno,
10:41
remotely, inexpensively,
203
629845
2539
na daljinu, jeftino,
10:44
with an accuracy at about 85 percent,
204
632408
3660
sa tačnošću od oko 85 procenata,
10:48
which is far better than chance level.
205
636092
2054
što je nogo bolje od slučajnosti.
10:51
And in addition, we discovered
a Pinocchio effect.
a Pinocchio effect.
206
639100
3790
Čak šta više, otkrili smo
Pinokijev efekat.
Pinokijev efekat.
10:56
No, not this Pinocchio effect.
207
644336
2055
Ne, ne ovaj Pinokijev efekat.
10:58
(Laughter)
208
646415
1007
(Smjeh)
10:59
This is the real Pinocchio effect.
209
647446
2122
Ovo je pravi Pinokijev efekat.
11:01
When people lie,
210
649592
1417
Kada ljudi lažu,
11:03
the facial blood flow
on the cheeks decreases,
on the cheeks decreases,
211
651033
3779
protok krvi u licu
na obrazima se smanjuje
na obrazima se smanjuje
11:06
and the facial blood flow
on the nose increases.
on the nose increases.
212
654836
3261
a na nosu se povećava.
11:11
Of course, lying is not the only situation
213
659379
3507
Naravno, laganje nije jedini slučaj
11:14
that will evoke our hidden emotions.
214
662910
2848
koji će prizvati naše skrivene emocije.
11:17
So then we asked ourselves,
215
665782
1874
Pa se onda pitamo,
11:19
in addition to detecting lies,
216
667680
2347
pored toga što detektuje laži,
11:22
how can our technology be used?
217
670051
2333
kako naša tehnologija može da se upotrebi?
11:25
One application is in education.
218
673027
3546
Jedna primjena je u obrazovanju.
11:28
For example, using this technology,
we can help this mathematics teacher
we can help this mathematics teacher
219
676597
4661
Na primer, koristeći ovu tehnologiju,
možemo pomoći ovom nastavniku matematike
možemo pomoći ovom nastavniku matematike
11:33
to identify the student in his classroom
220
681282
2907
da otkrije studenta u učionici
11:36
who may experience high anxiety
about the topic he's teaching
about the topic he's teaching
221
684213
4745
koji možda doživljava visok novo stresa
u vezi teme koju nastavnik predaje
u vezi teme koju nastavnik predaje
11:40
so that he can help him.
222
688982
1509
tako da može da mu pomogne.
11:43
And also we can use this in health care.
223
691337
2740
Također ovo možemo iskoristiti u zdravstvu
11:46
For example, every day I Skype my parents,
224
694101
3368
Na primjer, svakog dana se čujem sa
roditeljima preko Skajpa,
roditeljima preko Skajpa,
11:49
who live thousands of miles away.
225
697493
2082
koji žive hiljade milja daleko.
11:52
And using this technology,
226
700178
1821
I koristeći ovu tehnologiju,
11:54
I can not only find out
what's going on in their lives
what's going on in their lives
227
702023
3482
ne samo da mogu da otkrijem šta se dešava
u njihovim životima
u njihovim životima
11:57
but also simultaneously monitor
their heart rate, their stress level,
their heart rate, their stress level,
228
705529
6302
već istovremeno mogu pratiti broj otkucaja
srca, nivo stresa,
srca, nivo stresa,
12:03
their mood and whether or not
they are experiencing pain.
they are experiencing pain.
229
711855
3225
njihovo raspoloženje i da li ili ne
oni osjećaju bol.
oni osjećaju bol.
12:07
And perhaps in the future,
230
715839
1810
I možda u budućnosti,
12:09
their risks for heart attack
or hypertension.
or hypertension.
231
717673
3289
njihov rizik od srčanog udara ili
hipertenzije.
hipertenzije.
12:13
And you may ask:
232
721701
1260
I možda ćete pitati:
12:15
Can we use this also to reveal
politicians' emotions?
politicians' emotions?
233
723472
5481
Možemo li to iskoristiti da otkrijemo
emocije političara?
emocije političara?
12:20
(Laughter)
234
728977
1540
(Smjeh)
12:22
For example, during a debate.
235
730541
1854
Na primjer, tokom debate.
12:25
Well, the answer is yes.
236
733220
1453
Pa, odgovor je da.
12:27
Using TV footage,
237
735167
1944
Koristeći TV snimak,
12:29
we could detect
the politicians' heart rate,
the politicians' heart rate,
238
737135
4046
mogli bi otkriti broj otkucaja
njihovog srca,
njihovog srca,
12:33
mood and stress,
239
741205
2046
raspoloženje i stres,
12:35
and perhaps in the future,
whether or not they are lying to us.
whether or not they are lying to us.
240
743275
3578
i možda u budućnosti,
da li nas lažu ili ne.
da li nas lažu ili ne.
12:39
We can also use this
in marketing research,
in marketing research,
241
747495
2996
Ovo također možemo koristiti u
marketinškom istraživanju,
marketinškom istraživanju,
12:42
for example, to find out
242
750515
1851
da na primjer otkrijemo
12:44
whether or not people like
certain consumer products.
certain consumer products.
243
752390
4355
da li ljudi vole ili ne, određene
potrošačke proizvode.
potrošačke proizvode.
12:49
We can even use it in dating.
244
757229
2238
Možemo ovo koristiti i prilikom
zabavljanja.
zabavljanja.
12:51
So for example,
245
759904
1160
Tako na primjer,
12:53
if your date is smiling at you,
246
761088
2594
ako se vaš partner smješi
12:55
this technology can help you to determine
247
763706
2794
ova tehnologija vam može pomoći da
utvrdite
utvrdite
12:58
whether she actually likes you
248
766524
2607
da li joj se zapravo sviđate
13:01
or she is just trying to be nice to you.
249
769155
2175
ili samo hoće da bude fina prema vama.
13:03
And in this case,
250
771864
1695
A u ovom slučaju,
13:05
she is just trying to be nice to you.
251
773583
1876
samo pokušava da bude fina prema vama.
13:07
(Laughter)
252
775483
2392

3709
Transdermalna tehnologija optičkog
snimanja
snimanja
13:14
is at a very early stage of development.
254
782977

13:17
Many new applications will come about
that we don't know today.

4114
Mnoge nove primene za koje trenutno
ne znamo će se tek ustanoviti.
ne znamo će se tek ustanoviti.
13:22
However, one thing I know for sure
256
790293
2778
Ipak, jedno zasigurno znam,
13:25
is that lying will never
be the same again.
be the same again.
257
793095
3414
to da laganje nikada više neće
biti isto.

ABOUT THE SPEAKER
Kang Lee - Developmental researcherKang Lee has devoted his career to understanding the development of social cognition and behavior.
Why you should listen
With an international team based at the University of Toronto, Kang Lee investigates the neurological and social basis of emerging social behaviors in young children. His two-pronged research focuses first on how and when children develop the capacity to lie, to detect liesand to feel guilty about it afterwards.
The second focus of Lee's research is facial recognition, which has led to revelations of when children develop the ability to distinguish races and has helped explain why some people occasionally see Jesus' face on a piece of toast.
