You've probably heard of Pavlov's dogs,
1
13820
2439
Vjerojatno ste čuli za Pavlovljeve pse,
00:16
the phrase that often summarizes
2
16259
1740
frazu koja često sumira
00:17
Dr. Ivan Pavlov's early 20th century research,
3
17999
2878
istraživanje dr. Ivana Pavlova iz ranog 20. stoljeća,
00:20
in which he demonstrated that we can alter
4
20877
1911
u kojem je demonstrirao da možemo mijenjati
00:22
what stimuli elicit a reflective response in canines.
5
22788
3455
koji podražaji izazivaju refleksnu reakciju kod pasa.
00:26
He showed this by sounding a bell
6
26243
1907
Pokazao je to zvukom zvonca
00:28
just before he presented
7
28150
1381
tik prije no što je dao
00:29
his group of dogs with meat powder.
8
29531
2325
svojoj grupi pasa meso u prahu.
00:31
After many presentations of the bell,
9
31856
2366
Nakon mnogih zvonjenja zvona,
00:34
followed by tasty meat powder,
10
34222
1795
popraćenih ukusnim mesom u prahu,
00:36
the dogs eventually began to salivate
11
36017
2088
psi su najzad počeli sliniti
00:38
at just the sound of the bell.
12
38105
2200
na sami zvuk zvona.
00:40
They salivated even when
13
40305
1420
Slinili su čak i kad
00:41
there was no meat powder present.
14
41725
1884
nije bilo mesa u prahu.
00:43
This phenomenon isn't limited to dogs.
15
43609
2621
Ovaj fenomen nije isključivo prisutan u pasa.
00:46
Consider the placebo effect,
16
46230
1584
Sjetite se placebo efekta,
00:47
in which a pill with no active substances
17
47814
2628
u kojem tableta bez aktivnih supstanci
00:50
brings about a response
18
50442
1214
izaziva reakciju
00:51
similar to a pill with a substance present.
19
51656
2956
sličnu tableti sa supstancom.
00:54
What changes here is our reaction to our ailment,
20
54612
2607
Ono što je tu drugačije jest naša reakcija na bolest
00:57
such as perceiving less pain
21
57219
1604
kao što je smanjenje osjećaja boli,
00:58
and not the ailment itself.
22
58823
1842
a ne sama bolest.
01:00
Or, consider the love humans have for a parent.
23
60665
3149
Ili, uzmite ljubav koju ljudska bića osjećaju za roditelje.
01:03
Some would argue that this love is instinctual,
24
63814
2604
Neki tvrde da je ova ljubav instinktivna
01:06
and they may be partially right.
25
66418
1874
i možda su djelomično u pravu.
01:08
But, the argument fails to account
26
68292
1595
Ali ovaj argument ne uspijeva objasniti
01:09
for the equal amount of love
27
69887
1280
jednaku količinu ljubavi
01:11
that children adopted later in life
28
71167
2003
koju djeca posvojena u kasnijoj dobi života
01:13
hold for their adoptive parents.
29
73170
2170
imaju za svoje posvojitelje.
01:15
But the behaviorist argument can account
30
75340
1964
No, bihevioralni argument može objasniti
01:17
for both accounts of love.
31
77304
1630
oba oblika ljubavi.
01:18
A parent, biological or not,
32
78934
2247
Roditelj, biološki ili ne,
01:21
is constantly paired with things like
33
81181
2007
stalno biva uparen sa stvarima kao što su
01:23
food,
34
83188
536
01:23
smiles,
35
83724
631
hrana,
osmjesi,
01:24
toys,
36
84355
720
igračke,
01:25
affection,
37
85075
899
01:25
games,
38
85974
606
ljubav,
igre,
01:26
protection,
39
86580
697
zaštita,
01:27
and entertainment.
40
87277
1551
i zabava.
01:28
And a parent's constant association
41
88828
1785
I konstantna asocijacija roditelja
01:30
with these wonderful or crucial aspects of a child's life
42
90613
2709
s ovim predivnim ili ključnim aspektima djetetova života
01:33
has a similar, albeit more complicated,
43
93322
2371
ima sličan, doduše kompliciraniji,
01:35
effect that meat powder had on Pavlov's salivating dogs.
44
95693
3631
rezultat kao što je meso u prahu imalo na Pavlovljeve slineće pse.
01:39
In other words, if one's parent is predictive
45
99324
2307
Drugim riječima, ako je nečiji roditelj prediktor
01:41
of really good or really important things,
46
101631
2403
jako dobrih ili jako važnih stvari,
01:44
then one's parent becomes
47
104034
1171
tada taj roditelj postaje
01:45
a really good and important thing, too.
48
105205
2168
jako dobra i važna stvar, također.
01:47
And there is also romantic advice to be gained
49
107373
2500
Također, može se izvući i romantičan savjet
01:49
from Pavlov's observations.
50
109873
1881
iz Pavlovljevih opservacija.
01:51
We all need food to survive, right?
51
111754
2294
Svi trebamo hranu za preživljavanje, zar ne?
01:54
And someone who can provide such things
52
114048
1919
I netko tko nam može obezbijediti takve stvari
01:55
in a delicious, saliva-producing manner
53
115967
2447
na ukusan način, od kojeg nam cure sline
01:58
stands to become our human equivalent of a ringing bell.
54
118414
3515
služi nam kao ljudski ekvivalent zvona.
02:01
In other words,
55
121929
631
Drugim riječima,
02:02
if you can cook one or more scrumptious meals
56
122560
2330
ako znate skuhati jedan ili dva ukusna obroka
02:04
for a potential love interest,
57
124890
1419
za potencijalnog ljubavnika,
02:06
there's a good chance that you'll be viewed
58
126309
2100
postoji dobra šansa da će vam biti
02:08
more favorably in the future,
59
128409
1457
više naklonjeni u budućnosti,
02:09
even if you didn't prepare the delicious food.
60
129866
3408
čak i ako niste pripremili taj ukusan obrok.
02:13
And who wouldn't want the love of their life
61
133274
1503
A tko ne bi želio da njegova ljubav života
02:14
drooling over them?
62
134777
1584
slini po njemu?
02:16
But life is not just bell rings and salivation.
63
136361
2465
Ali život nije samo zvonjenje i slinjenje.
02:18
There's also a dark side to this type of learning,
64
138826
2666
Postoji i tamna strana ovakve vrste učenja,
02:21
called "taste aversion".
65
141492
1542
koja se zove "averzija okusa".
02:23
Taste aversion occurs when we ingest some food
66
143034
2376
Averzija okusa pojavljuje se kada progutamo neku hranu
02:25
that eventually makes us sick,
67
145410
1835
od koje nam na kraju bude zlo,
02:27
and, as a result, we avoid that food,
68
147245
3088
i kao rezultat, izbjegavamo tu hranu,
02:30
sometimes for the rest of our lives.
69
150333
2333
ponekad i do kraja života.
02:32
Taste aversion is so powerful
70
152666
1879
Averzija okusa je toliko snažna
02:34
that the effect can be seen
71
154545
1500
da se njen efekt očituje
02:36
even if the illness is experienced hours later
72
156045
3379
čak i kada se mučnina doživii satima kasnije
02:39
and even if the food itself did not actually make us sick.
73
159424
3063
i čak i kada nam ustvari nije pozlilo od te hrane.
02:42
Such is the case when we have the flu, and, by accident,
74
162487
3028
Primjerice, kada imamo gripu i kada slučajno
02:45
we ingest some food moments prior to vomiting.
75
165515
3543
pojedemo neku hranu tik prije povraćanja.
02:49
In this case, we know that the food
76
169058
1928
U ovom slučaju, znamo da hrana
02:50
did not cause the vomiting,
77
170986
1452
nije izazvala povraćanje,
02:52
but our bodies don't know that.
78
172438
1674
ali naša tijela to ne znaju.
02:54
And the next time we encounter that food,
79
174112
1966
I sljedeći put kada naiđemo na tu hranu,
02:56
we are likely to refuse eating it.
80
176078
2116
vjerojatno ćemo je odbiti jesti.
02:58
Now, imagine the potential consequences
81
178194
2424
Sada, zamislite moguće posljedice
03:00
of undercooking a meal on a first date.
82
180618
2494
potkuhavanja obroka na prvom spoju.
03:03
If the food makes your date sick,
83
183112
2170
Ako vašem spoju pozli,
03:05
it is possible for them
84
185282
1131
moguće je da će
03:06
to associate that bad feeling with not just the food,
85
186413
3217
asocirati taj loš osjećaj ne samo s tom hranom,
03:09
but with <i>your</i> food in particular.
86
189630
2791
nego s vašom hranom posebice.
03:12
If the episode was traumatizing enough,
87
192421
2297
Ako je iskustvo bilo dovoljno traumatično,
03:14
or if it also happens on a subsequent date,
88
194718
2712
ili ako se ponovi na sljedećem spoju,
03:17
they may come to relate you with the consequences,
89
197430
2752
mogli bi vas početi povezivati s tim posljedicama
03:20
just like Pavlov's dogs
90
200182
1884
baš kao što su i Pavlovljevi psi
03:22
related the bell with the meat powder.
91
202066
2224
povezivali zvonce s mesom u prahu.
03:24
In other words,
92
204290
856
Drugim riječima,
03:25
the sight of you showing up at the next dinner date
93
205146
2583
vaša pojava pri dolasku na idući spoj uz večeru
03:27
might actually make your date nauseous!
94
207729
2942
mogla bi mu izazvati mučninu!
03:30
As the old saying goes,
95
210671
980
Kao što stara izreka kaže,
03:31
the fastest way to someone's heart
96
211651
1710
najbrži način do nečijeg srca
03:33
is through their stomach,
97
213361
1420
je kroz njihov želudac,
03:34
assuming you don't make them sick in the process.
98
214781
2840
pod pretpostavkom da mu ne izazovete mučninu u procesu.
