1
00:00:00,959 --> 00:00:32,490
(MUSIC). My initial research and observational learning

2
00:00:32,860 --> 00:00:36,060
centered on the social modeling of aggression.

3
00:00:36,939 --> 00:00:38,200
In our experiment,

4
00:00:38,360 --> 00:00:41,430
preschool children observed an adult model

5
00:00:41,619 --> 00:00:43,159
beat up an inflated Bobo 

6
00:00:43,349 --> 00:00:43,439
doll

7
00:00:43,790 --> 00:00:45,349
in novel ways.

8
00:00:45,750 --> 00:00:47,409
She pummeled it with a mallet,

9
00:00:47,740 --> 00:00:49,310
flung it in the air,

10
00:00:50,819 --> 00:00:52,279
kicked it repeatedly,

11
00:00:53,729 --> 00:00:55,490
and threw it down and beat it.

12
00:00:55,750 --> 00:00:59,500
And these novel acts were embellished with hostile remarks.

13
00:01:02,909 --> 00:01:05,410
The children were then left in the playroom

14
00:01:05,650 --> 00:01:07,599
that had a variety of toys.

15
00:01:11,230 --> 00:01:14,139
Now, the children who had observed the aggressive modeling

16
00:01:14,339 --> 00:01:15,489
adopted much of it.

17
00:01:20,019 --> 00:01:23,739
They even invented new ways for attacking the doll.

18
00:01:27,699 --> 00:01:30,620
Children who had not observed the adult model

19
00:01:30,849 --> 00:01:33,250
were less aggressive and never hit the Bobo 

20
00:01:33,440 --> 00:01:35,919
doll in the novel ways that were bottled.

21
00:01:37,400 --> 00:01:40,800
The children who had been exposed to the aggressive modeling

22
00:01:40,970 --> 00:01:43,489
showed an increased attraction to guns

23
00:01:43,660 --> 00:01:46,500
even though the adult model never used them.

24
00:01:48,419 --> 00:01:50,819
At the time we did this research,

25
00:01:51,160 --> 00:01:55,080
it was widely believed that seeing others venting aggression

26
00:01:55,360 --> 00:01:58,410
would drain away the viewer's aggressive drive.

27
00:01:58,699 --> 00:01:59,849
As you can see,

28
00:02:00,059 --> 00:02:03,940
exposure to modeled aggression is hardly cathartic.

29
00:02:07,019 --> 00:02:10,270
Televised violence has four major effects.

30
00:02:10,758 --> 00:02:13,399
It teaches aggressive styles of behavior,

31
00:02:14,080 --> 00:02:16,899
weakens restraints over aggression,

32
00:02:17,669 --> 00:02:21,919
desensitizes and habituates viewers to human cruelty

33
00:02:22,460 --> 00:02:25,330
and shapes viewers images of reality.

34
00:02:27,100 --> 00:02:31,339
With the enormous advances in the technology of communication,

35
00:02:32,029 --> 00:02:35,309
observational learning from the symbolic environment

36
00:02:35,729 --> 00:02:38,789
is placing an increasingly powerful role

37
00:02:39,039 --> 00:02:40,710
in people's everyday lives.

38
00:02:42,630 --> 00:02:43,929
Human attitudes,

39
00:02:46,199 --> 00:02:47,380
values,

40
00:02:47,759 --> 00:02:49,449
styles of behavior

41
00:02:50,360 --> 00:02:52,460
are now being modeled worldwide.

42
00:02:54,110 --> 00:02:55,559
As a result,

43
00:02:55,660 --> 00:02:57,089
televised modeling

44
00:02:57,419 --> 00:03:01,570
is becoming an influential vehicle for political

45
00:03:01,869 --> 00:03:03,210
and social change.

46
00:03:03,910 --> 00:03:06,429
We now have global broadcasts

47
00:03:06,779 --> 00:03:08,410
of societal conflicts

48
00:03:08,559 --> 00:03:10,210
as they are happening.
