Da li su deca loši lažovi? Da li mislite da lako možete da prepoznate njihove laži? Istraživač razvojne psihologije, Kang Li, izučava šta se psihološki dešava deci kada lažu. Ona to često rade, počinju još sa dve godine i zapravo su veoma dobra u tome. Li objašnjava zašto bi trebalo da slavimo kad dete počne da laže i predstavlja nam novu tehnologiju za prepoznavanje laži, koja bi jednog dana mogla da razotkrije naše skriven emocije.

Zdravo.
00:14
Let me ask the audience a question:
1
2461
2346
Postaviću publici pitanje:
00:16
Did you ever lie as a child?
2
4831
2195
da li ste ikad slagali kad ste bili dete?
00:19
If you did, could you please
raise your hand?
raise your hand?

7050
2667
Ako jeste, možete li, molim vas,
da podignete ruke?
da podignete ruke?
00:23
Wow! This is the most honest
group of people I've ever met.
group of people I've ever met.

11145

Opa! Ovo je najiskrenija grupa ljudi
koju sam ikad upoznao.
koju sam ikad upoznao.
00:26
(Laughter)
5
14623
1957
(Smeh)
00:28
So for the last 20 years,
6
16604
1709
Dakle, proteklih 20 godina
00:30
I've been studying
how children learn to tell lies.
how children learn to tell lies.
7
18337
3415
sam izučavao kako deca uče da govore laži.
00:33
And today, I'm going to share with you
8
21776
2304
A danas ću da podelim sa vama
00:36
some of the discoveries we have made.
9
24104
2162
neka od otkrića do kojih smo došli.
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 ću da vam ispričam priču
g. Ričarda Mesine,
g. Ričarda Mesine,
00:43
who is my friend and an elementary
school principal.
school principal.
11
31573
3129
koji je moj prijatelj
i direktor osnovne škole.
i direktor osnovne škole.
00:47
He got a phone call one day.
12
35266
1561
Jednog dana je primio telefonski poziv.
00:51
The caller says,
13
39279
1151
Sagovornik 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
neće doći u školu danas
00:56
because he's sick."
15
44360
1463
jer je bolestan."
00:58
Mr. Messina asks,
16
46498
1736
G. Mesina je pitao:
01:00
"Who am I speaking to, please?"
17
48258
2014
"Izvinite, s kim razgovaram?"
01:02
And the caller says,
18
50788
1490
A sagovornik je rekao:
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
Dakle, 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
savršeno spaja
tri uobičajena verovanja koja imamo
tri uobičajena verovanja 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
Pod jedan: deca tek počinju da lažu
01:24
after entering elementary school.
26
72795
2268
nakon polaska u osnovnu školu.
01:27
Two, children are poor liars.
27
75552
2311
Dva: deca su loši lažovi.
01:29
We adults can easily detect their lies.
28
77887
2857
Mi odrasli možemo lako
da prepoznamo njihove laži.
da prepoznamo 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
u veoma ranom uzrastu,
u veoma ranom uzrastu,
01:36
there must be some
character flaws with them,
character flaws with them,
30
84830
2849
mora da imaju neku karakternu manu
01:39
and they are going to become
pathological liars for life.
pathological liars for life.
31
87703
4049
i da će ostati patološki lažovi
do kraja života.
do kraja života.
01:44
Well, it turns out
32
92720
2194
Pa, ispostavlja se
01:46
all of the three beliefs are wrong.
33
94938
2298
da su sva tri verovanja 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
s decom širom sveta.
01:55
Here is an example.
36
103457
1486
Evo jednog primera.
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
Dakle, u ovoj igri, tražili smo od dece
da pogode brojeve na kartama.
da pogode brojeve na kartama.
02:01
And we tell them if they win the game,
38
109958
2878
A mi im kažemo da ako pobede u igri,
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
izvinimo se i napustimo prostoriju.
02:13
And before we leave the room,
42
121763
1934
A pre nego što napustimo prostoriju,
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
imamo skrivene kamere u prostoriji
02:23
to watch their every move.
46
131143
1795
koje prate 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
Jer je žudnja
da pobede u igri tako snažna,
da pobede u igri tako snažna,
02:29
more than 90 percent of children will peek
48
137657
3486
više od 90 procenata dece će virnuti,
02:33
as soon as we leave the room.
49
141167
1437
čim napustimo prostoriju.
02:34
(Laughter)
50
142628
2000
(Smeh)
02:37
The crucial question is:
51
145044
1986
Ključno pitanje je:
02:39
When we return and ask the children
52
147054
2748
kad se vratimo i upitamo decu
02:41
whether or not they have peeked,
53
149826
2309
da li su virila,
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 će lagati o svom prestupu?
02:51
We found that regardless
of gender, country, religion,
of gender, country, religion,
56
159525
4773
Otkrili smo da bez obzira
na rod, državu, religiju,
na rod, državu, religiju,
02:56
at two years of age,
57
164934
1579
u dvogodišnjem uzrastu
02:59
30 percent lie,
58
167188
1927
30 procenata njih slaže,
03:01
70 percent tell the truth
about their transgression.
about their transgression.
59
169139
3809
70 procenata kaže istinu
o svom prestupu.
o svom prestupu.
03:04
At three years of age,
60
172972
2138
U trogodišnjem uzrastu,
03:07
50 percent lie and 50 percent
tell the truth.
tell the truth.
61
175134
3474
50 procenata slaže,
a 50 procenata kaže istinu.
a 50 procenata kaže istinu.
03:11
At four years of age,
62
179302
1899
U četvorogodišnjem uzrastu,
03:13
more than 80 percent lie.
63
181225
1947
više od 80 procenata slaže.
03:16
And after four years of age,
64
184334
2451
A nakon četvrte godine
03:18
most children lie.
65
186809
1389
većina dece laže.
Pa, kao što možete da vidite,
03:21
So as you can see,
66
189180
1363
03:22
lying is really a typical part
of development.
of development.
67
190567
3463
laganje je karakterističan deo razvoja.
03:26
And some children begin to tell lies
68
194054
2790
A neka deca počinju da lažu
03:28
as young as two years of age.
69
196868
2439
još u uzrastu od dve godine.
03:32
So now, let's take a closer look
at the younger children.
at the younger children.
70
200438
3557
Sad, pogledajmo pažljivije
decu mlađeg uzrasta.
decu mlađeg uzrasta.
03:37
Why do some but not all
young children lie?
young children lie?
71
205336
3813
Zašto neka, ali ne i sva deca lažu?
03:42
In cooking, you need good ingredients
72
210184
3329
U kulinarstvu su vam potrebni
dobri sastojci
dobri sastojci
03:45
to cook good food.
73
213537
1613
da biste spremili dobru hranu.
03:47
And good lying requires
two key ingredients.
two key ingredients.
74
215793
4563
Za svako dobro laganje
su potrebna dva sastojka.
su potrebna dva sastojka.
03:53
The first key ingredient
is theory of mind,
is theory of mind,
75
221109
4110
Prvi ključni sastojak je teorija uma,
03:57
or the mind-reading ability.
76
225243
1835
iliti sposobnost čitanja misli.
03:59
Mind reading is the ability to know
77
227768
2078
Čitanje misli je sposonost spoznaje
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 situaciji
različito znanje o situaciji
04:06
and the ability to differentiate
between what I know
between what I know
79
234502
3801
i sposobnost razlikovanja
između onoga što ja znam
između onoga što ja znam
04:10
and what you know.
80
238327
1223
i 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
jer je osnova laganja to da ja znam
04:18
you don't know
83
246056
1151
da vi ne znate
04:19
what I know.
84
247231
1151
ono što ja znam.
04:20
Therefore, I can lie to you.
85
248406
1371
Stoga mogu da vam lažem.
04:23
The second key ingredient
for good lying is self-control.
for good lying is self-control.
86
251070
4610
Drugi ključni sastojak
za dobro laganje je samokontrola.
za dobro laganje je samokontrola.
04:27
It is the ability to control your speech,
your facial expression
your facial expression
87
255704
4623
To je sposobnost kontrolisanja govora,
vašeg izraza lica
vašeg izraza lica
04:32
and your body language,
88
260351
1540
i vašeg govora tela,
04:33
so that you can tell a convincing lie.
89
261915
2078
kako biste mogli da kažete uverljivu laž.
04:36
And we found that those young children
90
264938
3726
A otkrili smo da ona dečica
04:40
who have more advanced mind-reading
and self-control abilities
and self-control abilities
91
268688
4856
koja su naprednija u sposobnostima
čitanja misli i samokontrole
čitanja misli i samokontrole
04:45
tell lies earlier
92
273568
2038
ranije počinju da lažu
04:47
and are more sophisticated liars.
93
275630
2816
i prefinjeniji su lažovi.
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
Kako se ispostavilo, te dve sposobnosti
su suštinske za sve nas
su suštinske za sve nas
04:57
to function well in our society.
95
285530
2522
da bismo dobro funkcionisali u društvu.
05:00
In fact, deficits in mind-reading
and self-control abilities
and self-control abilities
96
288848
4335
Zapravo, nedostatak sposobnosti
čitanja misli i samokontrole
čitanja 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
poput hiperaktivnog poremećaja i autizma.
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
Pa, ako otkrijete da vaš dvogodišnjak
izgovara svoju prvu laž,
izgovara svoju prvu laž,
05:19
instead of being alarmed,
100
307094
1984
umesto da budete uznemireni,
05:21
you should celebrate --
101
309102
1492
trebalo bi da slavite -
05:22
(Laughter)
102
310618
1522
(Smeh)
05:24
because it signals that your child
has arrived at a new milestone
has arrived at a new milestone
103
312164
5730
jer je to znak da je vaše dete
stiglo do nove prekretnice
stiglo do nove prekretnice
05:29
of typical development.
104
317918
1635
u tipičnom razvoju.
05:33
Now, are children poor liars?
105
321085
3136
Sad, da li su deca loši lažovi?
05:36
Do you think you can easily
detect their lies?
detect their lies?
106
324878
2994
Mislite li da lako možete
da prepoznate njihove laži?
da prepoznate njihove laži?
05:40
Would you like to give it a try?
107
328745
1678
Da li biste se okušali u tome?
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
Na snimcima
05:48
the children are going to respond
to a researcher's question,
to a researcher's question,
111
336199
3057
deca če da odgovaraju
na pitanje istraživača:
na pitanje istraživača:
05:51
"Did you peek?"
112
339280
1482
"Da li ste virili?"
05:52
So try to tell me
113
340786
1554
Pa, pokušajte da mi kažete
05:54
which child is lying
114
342364
1398
koje dete laže,
05:55
and which child is telling the truth.
115
343786
2110
a koje dete govori istinu.
05:58
Here's child number one.
116
346272
1719
Evo prvog deteta.
06:00
Are you ready?
117
348991
1237
Jeste li spremni?
06:03
(Video) Adult: Did you peek? Child: No.
118
351006
1920
(Snimak) Odrasla osoba: Da li si virio?
Dete: Ne.
Dete: Ne.
06:05
Kang Lee: And this is child number two.
119
353619
2236
Kang Li: A ovo je drugo dete.
06:09
(Video) Adult: Did you peek? Child: No.
120
357501
2192
(Snimak) Odrasla osoba: Da li si virila?
Dete: Ne.
Dete: Ne.
06:13
KL: OK, if you think
child number one is lying,
child number one is lying,
121
361296
3587
KL: U redu, ako mislite da prvo dete laže,
06:16
please raise your hand.
122
364907
1687
molim vas da podignete ruke.
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 drugo dete laže,
molim vas da podignete ruke.
molim vas da podignete ruke.
06:25
OK, so as a matter of fact,
124
373593
2474
U redu, zapravo,
06:28
child number one is telling the truth,
125
376091
2937
prvo dete govori istinu,
06:31
child number two is lying.
126
379052
2029
drugo dete 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 užasni
u prepoznavanju dečjih laži.
u prepoznavanju dečjih laži.
06:37
(Laughter)
128
385378
2478
(Smeh)
06:39
Now, we have played similar kinds of games
129
387880
3384
Sad, igrali smo slične igre
06:43
with many, many adults
from all walks of life.
from all walks of life.
130
391288
4625
s mnogim, mnogim odraslim ljudima
raznih zanimanja.
raznih zanimanja.
06:48
And we show them many videos.
131
396714
2158
Pokazivali smo im mnogo snimaka.
06:51
In half of the videos, the children lied.
132
399347
2549
Na polovini snimaka su deca lagala.
06:53
In the other half of the videos,
the children told the truth.
the children told the truth.
133
401920
3267
Na drugoj polovini snimaka
deca su govorila istinu.
deca su govorila istinu.
06:58
And let's find out
how these adults performed.
how these adults performed.
134
406529
2857
Hajde da vidimo
kakav je učinak ovih odraslih.
kakav je učinak ovih odraslih.
07:02
Because there are as many liars
as truth tellers,
as truth tellers,
135
410319
3855
Zato što ima jednak broj
lažova i onih koji govore istinu,
lažova i onih koji govore istinu,
07:06
if you guess randomly,
136
414198
2399
ako nasumično pogađate,
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.
07:12
So if your accuracy is around 50 percent,
138
420715
3594
Pa, ako su vaši pogoci oko 50 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 užasni
u prepoznavanju dečjih laži.
u prepoznavanju dečjih laži.
07:20
So let's start with undergrads
and law school students,
and law school students,
140
428290
4529
Pa, počnimo sa redovnim studentima
i studentima prava,
i studentima prava,
07:24
who typically have
limited experience with children.
limited experience with children.
141
432843
3672
koji obično imaju
ograničeno iskustvo s decom.
ograničeno iskustvo s decom.
07:30
No, they cannot detect children's lies.
142
438038
1962
Ne, ne znaju da prepoznaju dečje laži.
07:32
Their performance is around chance.
143
440024
2214
Njihov učinak je na nivou
slučajnog pogađanja.
slučajnog pogađanja.
07:34
Now how about social workers
and child-protection lawyers,
and child-protection lawyers,
144
442262
5229
Sad, šta je sa socijalnim radnicima
i advokatima za zaštitu dece,
i advokatima za zaštitu dece,
07:39
who work with children on a daily basis?
145
447515
2674
koji svakodnevno rade s decom?
07:42
Can they detect children's lies?
146
450213
2087
Mogu li oni prepoznati dečje laži?
07:45
No, they cannot.
147
453624
1151
Ne, ne mogu.
07:46
(Laughter)
148
454799
1045
(Smeh)
07:47
What about judges,
149
455868
1472
Šta je sa sudijama,
07:49
customs officers
150
457364
1800
carinicima
07:51
and police officers,
151
459188
1858
i policajcima,
07:53
who deal with liars on a daily basis?
152
461070
2643
koji se svakodnevno bave lažovima?
07:55
Can they detect children's lies?
153
463737
1917
Mogu li oni da prepoznaju dečje laži?
07:58
No, they cannot.
154
466800
1214
Ne, ne mogu.
08:00
What about parents?
155
468430
1186
Šta je s roditeljima?
08:01
Can parents detect other children's lies?
156
469640
3014
Mogu li roditelji da prepoznaju
laži kod tuđe dece?
laži kod tuđe dece?
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
Šta je sa tim da li roditelji
mogu da prepoznaju laži sopstvene dece?
mogu da prepoznaju laži sopstvene dece?
08:13
No, they cannot.
159
481208
1201
Ne, ne mogu.
08:14
(Laughter) (Applause)
160
482433
3476
(Smeh) (Aplauz)
08:17
So now you may ask
161
485933
1547
Dakle, sad se možda pitate
08:20
why children's lies
are so difficult to detect.
are so difficult to detect.
162
488504
3632
zašto je tako teško prepoznati dečje laži.
08:24
Let me illustrate this
with my own son, Nathan.
with my own son, Nathan.
163
492958
3012
Dozvolite mi da vam to ilustrujem
na primeru mog sina, Nejtana.
na primeru mog 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
kad laže.
08:31
(Laughter)
166
499595
2206
(Smeh)
08:33
So when children lie,
167
501825
1602
Pa, kad deca lažu
08:35
their facial expression
is typically neutral.
is typically neutral.
168
503451
3156
njihovi izrazi lica su obično neutralni.
08:39
However, behind this neutral expression,
169
507123
3460
Međutim, iza ovog neutralnog izraza,
08:42
the child is actually experiencing
a lot of emotions,
a lot of emotions,
170
510607
3326
dete zapravo proživljava mnoge emocije,
08:45
such as fear, guilt, shame
171
513957
3855
poput straha, krivice, srama,
08:49
and maybe a little bit of liar's delight.
172
517836
3096
a možda i blagog užitka u laganju.
08:52
(Laughter)
173
520956
2702
(Smeh)
08:55
Unfortunately, such emotions
are either fleeting or hidden.
are either fleeting or hidden.
174
523682
4840
Nažalost, slične emocije
su prolazne ili skrivene.
su prolazne ili skrivene.
09:00
Therefore, it's mostly invisible to us.
175
528546
3099
Stoga su nam uglavnom nevidljive.
Te smo u proteklih pet godina
09:03
So in the last five years,
176
531669
1359
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 da otkrijemo način
da razotkrijemo ove skrivene emocije.
da razotkrijemo ove skrivene emocije.
09:08
Then we made a discovery.
178
536972
1514
Onda smo došli do otkrića.
09:11
We know that underneath our facial skin,
179
539273
3185
Znamo da ispod kože lica
09:14
there's a rich network of blood vessels.
180
542482
3394
imamo bogatu mrežu krvnih sudova.
09:17
When we experience different emotions,
181
545900
2417
Kada proživljavamo različite emocije,
09:20
our facial blood flow changes subtly.
182
548341
2641
tok krvi u našem licu se blago menja.
09:23
And these changes are regulated
by the autonomic system
by the autonomic system
183
551613
3948
A ove promene reguliše autonomni sistem
09:27
that is beyond our conscious control.
184
555585
2169
koji je mimo naše svesne kontrole.
09:30
By looking at facial blood flow changes,
185
558159
3823
Posmatranjem promena
u proticanju krvi na licu,
u proticanju krvi na licu,
09:34
we can reveal people's hidden emotions.
186
562006
2697
možemo da razotkrijemo
skrivene emocije kod ljudi.
skrivene emocije kod ljudi.
09:37
Unfortunately, such emotion-related
facial blood flow changes
facial blood flow changes
187
565229
4778
Nažalost, slične promene toka krvi na licu
uzrokovane emocijama
uzrokovane emocijama
09:42
are too subtle to detect by our naked eye.
188
570031
2625
su suviše suptilne
da bismo ih zapazili golim okom.
da bismo ih zapazili golim okom.
09:45
So to help us reveal
people's facial emotions,
people's facial emotions,
189
573632
3768
Pa, kao pomoć u razotkrivanju
skrivenih emocija kod ljudi,
skrivenih emocija kod ljudi,
09:49
we have developed a new imaging technology
190
577424
3034
razvili smo novu tehnologiju prikazivanja,
09:52
we call "transdermal optical imaging."
191
580482
3149
nazivamo je: "transdermalno
optičko prikazivanje".
optičko prikazivanje".
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 postigli, koristimo obične
video kamere da bismo snimali ljude
video kamere da bismo snimali ljude
10:00
when they experience
various hidden emotions.
various hidden emotions.
193
588656
3086
dok doživljavaju
različite skrivene emocije.
različite skrivene emocije.
10:04
And then, using our image
processing technology,
processing technology,
194
592385
4094
A potom, koristeći našu
tehnologiju za obradu slika,
tehnologiju za obradu slika,
10:08
we can extract transdermal images
of facial blood flow changes.
of facial blood flow changes.
195
596503
5536
možemo da izdvojimo transdermalne slike
promena u toku krvi na licu.
promena u toku krvi na licu.
10:16
By looking at transdermal video images,
196
604475
4272
Posmatranjem transdermalnih video snimaka,
10:20
now we can easily see
197
608771
1787
sada možemo lako da vidimo
10:23
facial blood flow changes associated
with the various hidden emotions.
with the various hidden emotions.
198
611737
5631
promene u toku krvi na licu povezane
s različitim skrivenim emocijama.
s različitim skrivenim emocijama.
10:29
And using this technology,
199
617944
1788
A koristeći ovu tehnologiju,
10:31
we can now reveal the hidden emotions
associated with lying,
associated with lying,
200
619756
4668
sad možemo da otkrijemo skrivene emocije
koje su u vezi sa laganjem,
koje su u vezi sa laganjem,
10:36
and therefore detect people's lies.
201
624448
2910
i samim tim prepoznamo kad ljudi lažu.
10:39
We can do so noninvasively,
202
627382
2439
Možemo to da postignemo neinvazivno,
10:41
remotely, inexpensively,
203
629845
2539
s udaljenosti, jeftino,
10:44
with an accuracy at about 85 percent,
204
632408
3660
s preciznošću od oko 85 procenata,
10:48
which is far better than chance level.
205
636092
2054
što je daleko bolje od nivoa nagađanja.
10:51
And in addition, we discovered
a Pinocchio effect.
a Pinocchio effect.
206
639100
3790
A uz sve to, otkrili smo efekat Pinokija.
10:56
No, not this Pinocchio effect.
207
644336
2055
Ne, ne ovaj efekat Pinokija.
10:58
(Laughter)
208
646415
1007
(Smeh)
10:59
This is the real Pinocchio effect.
209
647446
2122
Ovo je stvarni efekat Pinokija.
11:01
When people lie,
210
649592
1417
Kad ljudi lažu,
11:03
the facial blood flow
on the cheeks decreases,
on the cheeks decreases,
211
651033
3779
tok krvi na licu
se smanjuje u predelu obraza,
se smanjuje u predelu obraza,
11:06
and the facial blood flow
on the nose increases.
on the nose increases.
212
654836
3261
a tok krvi na licu
u predelu nosa se pojačava.
u predelu nosa se pojačava.
11:11
Of course, lying is not the only situation
213
659379
3507
Naravno, laganje nije jedina situacija
11:14
that will evoke our hidden emotions.
214
662910
2848
koja će da izazove vaše skrivene emocije.
11:17
So then we asked ourselves,
215
665782
1874
Pa smo se zapitali,
11:19
in addition to detecting lies,
216
667680
2347
pored prepoznavanja laži,
11:22
how can our technology be used?
217
670051
2333
kako naša tehnologija može da se koristi?
11:25
One application is in education.
218
673027
3546
Jedna njena primena 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, upotrebom ove tehnologije
možemo pomoći ovom nastavniku matematike
možemo pomoći ovom nastavniku matematike
11:33
to identify the student in his classroom
220
681282
2907
da prepozna đaka 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 izrazit nespokoj
zbog teme koja se predaje,
zbog teme koja se predaje,
11:40
so that he can help him.
222
688982
1509
te može da mu pomogne.
11:43
And also we can use this in health care.
223
691337
2740
Takođe ovo možemo
da koristimo u zdravstvu.
da koristimo u zdravstvu.
11:46
For example, every day I Skype my parents,
224
694101
3368
Na primer, svakodnevno se čujem
s roditeljima preko Skajpa,
s roditeljima preko Skajpa,
11:49
who live thousands of miles away.
225
697493
2082
koji žive hiljadama kilometara daleko.
11:52
And using this technology,
226
700178
1821
A upotrebom ove tehnologije,
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,
šta se dešava 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 i da istovremeno pratim
njihov rad srca, nivo stresa,
njihov rad srca, nivo stresa,
12:03
their mood and whether or not
they are experiencing pain.
they are experiencing pain.
229
711855
3225
raspoloženje i da li doživljavaju bol.
12:07
And perhaps in the future,
230
715839
1810
A možda nekad u budućnosti
12:09
their risks for heart attack
or hypertension.
or hypertension.
231
717673
3289
rizik od srčanog udara
ili visokog krvnog pritiska kod njih.
ili visokog krvnog pritiska kod njih.
12:13
And you may ask:
232
721701
1260
I možda se pitate:
12:15
Can we use this also to reveal
politicians' emotions?
politicians' emotions?
233
723472
5481
možemo li ovo da koristimo
i da bismo razotkrili emocije političara?
i da bismo razotkrili emocije političara?
12:20
(Laughter)
234
728977
1540
(Smeh)
12:22
For example, during a debate.
235
730541
1854
Na primer, 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 televizijski materijal,
12:29
we could detect
the politicians' heart rate,
the politicians' heart rate,
238
737135
4046
možemo da otkrijemo
broj otkucaja srca kod političara,
broj otkucaja srca kod političara,
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
a možda nekad u budućnosti
i da li nam lažu.
i da li nam lažu.
12:39
We can also use this
in marketing research,
in marketing research,
241
747495
2996
Takođe, ovo možemo da koristimo
u marketinškim istraživanjima,
u marketinškim istraživanjima,
12:42
for example, to find out
242
750515
1851
na primer, da otkrijemo
12:44
whether or not people like
certain consumer products.
certain consumer products.
243
752390
4355
da li se ljudima sviđa neki proizvod.
12:49
We can even use it in dating.
244
757229
2238
Možemo ga čak koristiti prilikom izlazaka.
12:51
So for example,
245
759904
1160
Pa, na primer,
12:53
if your date is smiling at you,
246
761088
2594
ako vam se pratilja smeši,
12:55
this technology can help you to determine
247
763706
2794
ova tehnologija
vam može pomoći da odredite
vam može pomoći da odredite
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 pokušava da bude ljubazna.
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 ljubazna.
13:07
(Laughter)
252
775483
2392
(Smeh)
13:11
So transdermal optical imaging technology
253
779244
3709
Dakle, transdermalna tehnologija
optičkog prikazivanja
optičkog prikazivanja
13:14
is at a very early stage of development.
254
782977
2578
je na veoma ranom stadijumu razvoja.
13:17
Many new applications will come about
that we don't know today.
that we don't know today.
255
785579
4114
Mnoge nove primene će da iskrsnu,
za koje danas ne znamo.
za koje danas ne znamo.
13:22
However, one thing I know for sure
256
790293
2778
Međutim, jedno znam sigurno,
13:25
is that lying will never
be the same again.
be the same again.
257
793095
3414
a to je da laganje
više nikad neće biti isto.
više nikad neće biti isto.
13:28
Thank you very much.
258
796533
1158
Mnogo vam hvala.

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.
