Hi, my name is Brian Collin. And today's topic is on the theories of emotion.

00:00:05,829 --> 00:00:09,159
Click on the link in this description to take a practice

3
00:00:09,170 --> 00:00:12,739
test that I created using the Learnmytest study tool.

4
00:00:12,750 --> 00:00:16,158
Remember that the best way to study is to take practice tests.

5
00:00:16,180 --> 00:00:20,420
If you don't have good practice tests, make your own and learn while you do it

6
00:00:20,600 --> 00:00:24,520
or search our growing list of test banks for one in your field of study.

00:00:29,329 --> 00:00:30,729
To begin this discussion,

9
00:00:30,739 --> 00:00:32,740
let's assume that you were camping with a

10
00:00:32,750 --> 00:00:36,060
friend and a bear stumbles upon your campsite.

11
00:00:36,250 --> 00:00:39,630
You are afraid for your life that the bear might attack you.

12
00:00:41,389 --> 00:00:46,869
The James Lange theory argues that you first noticed the stimulus, which

13
00:00:46,880 --> 00:00:50,189
in your case would be seeing a bear at your campsite.

14
00:00:51,630 --> 00:00:55,180
Then because you see it, the bear at your campsite,

15
00:00:55,200 --> 00:00:58,209
you start having physiological responses.

16
00:00:58,220 --> 00:01:01,610
Your heart starts beating really fast and you start sweating.

17
00:01:03,549 --> 00:01:07,279
So, because you are sweating and your heart starts beating quickly,

18
00:01:07,379 --> 00:01:09,269
you realize that you are scared.

19
00:01:09,360 --> 00:01:14,129
The James Lange theory argues that emotions such as feeling fear

20
00:01:14,139 --> 00:01:17,930
are a result of how your body responds to a stimulus.

21
00:01:18,129 --> 00:01:19,050
So, in essence,

22
00:01:19,059 --> 00:01:21,669
it's saying that you feel fear because you

23
00:01:21,680 --> 00:01:24,250
start sweating and your heart starts beating fast.

24
00:01:24,260 --> 00:01:26,809
Do you really think that you feel fear because your

25
00:01:26,819 --> 00:01:29,589
heart starts beating fast or because you start sweating?

26
00:01:29,819 --> 00:01:33,819
So, if you're playing a sport and have the same physiological response,

27
00:01:33,830 --> 00:01:36,169
does that mean you're going to experience fear?

28
00:01:36,330 --> 00:01:37,800
Maybe, maybe not.

29
00:01:37,809 --> 00:01:40,389
Which is why the James Lang theory is not

30
00:01:40,400 --> 00:01:43,160
one of the more accepted theories on emotions.

31
00:01:44,339 --> 00:01:50,029
The Canon-Bard theory argues that you first see the stimulus or notice the stimulus.

32
00:01:50,040 --> 00:01:53,589
So, in your case would be seeing a bear at your campsite.

33
00:01:55,260 --> 00:01:58,930
Then you experience the physiological response such

34
00:01:58,940 --> 00:02:01,720
as sweating and your heart beating rapidly.

35
00:02:04,129 --> 00:02:08,710
At the same exact time, you also experience the emotion.

36
00:02:08,990 --> 00:02:13,000
So, in your case, at the campsite, the emotion would be feeling fear.

37
00:02:13,289 --> 00:02:16,600
So, the Cannon-Bard theory argues that you experience the

38
00:02:16,610 --> 00:02:20,330
physiological response and the emotion at the same time.

39
00:02:20,520 --> 00:02:22,589
Unlike the James-Lange theory,

40
00:02:22,619 --> 00:02:26,710
the Cannon-Bard theory does not indicate that you feel an emotion

41
00:02:26,850 --> 00:02:30,009
because you have a physiological response.

42
00:02:30,160 --> 00:02:33,710
Do you agree with the Canon-Bard theory? Why or why not?

43
00:02:35,210 --> 00:02:39,619
The Schachter-Singer theory argues that you first see the stimulus.

44
00:02:39,630 --> 00:02:43,009
So, in your case would be seeing a bear at your campsite.

45
00:02:44,729 --> 00:02:47,380
Then you have your physiological response.

46
00:02:47,389 --> 00:02:51,149
So, your heart starts beating fast and you start sweating.

47
00:02:53,169 --> 00:02:57,869
Schachter-Singer argued that at the same time as your physiological response,

48
00:02:58,009 --> 00:02:59,820
you would appraise the situation,

49
00:02:59,830 --> 00:03:03,429
which meant identifying the stimulus and understanding why

50
00:03:03,440 --> 00:03:05,470
it has led you to feel that emotion.

51
00:03:05,639 --> 00:03:07,169
So, in your example,

52
00:03:07,250 --> 00:03:10,059
there is a bear at my campsite that could

53
00:03:10,070 --> 00:03:13,169
attack me or hurt me and therefore I'm scared.

54
00:03:14,830 --> 00:03:17,970
So, as a result of both your physiological

55
00:03:17,979 --> 00:03:21,169
response and your cognitive appraisal of the situation,

56
00:03:21,300 --> 00:03:24,910
you experience the emotion, which in your case would be fear.

57
00:03:24,979 --> 00:03:26,309
So, what do you think about the

58
00:03:26,449 --> 00:03:27,750
Schachter-Singer theory?

59
00:03:27,779 --> 00:03:32,130
Do you think it's a better or worse theory than the Cannon-Bard or James-Lange theory?

60
00:03:34,149 --> 00:03:38,630
The Lazarus's Cognitive Mediational Theory argues that

61
00:03:38,809 --> 00:03:43,929
you first see the stimulus. So, in your case would be seeing a bear at your campsite.

62
00:03:45,199 --> 00:03:49,130
Then you have a cognitive appraisal of the situation

63
00:03:49,320 --> 00:03:52,979
and understand why it may cause a particular emotion.

64
00:03:53,110 --> 00:03:57,660
So, in your case, you might think there's a bear that could attack or hurt me,

65
00:03:57,729 --> 00:03:59,179
therefore I'm scared.

66
00:04:00,820 --> 00:04:03,399
Then because you appraise the situation,

67
00:04:03,529 --> 00:04:04,800
you feel the emotion.

68
00:04:04,940 --> 00:04:09,880
So, essentially because you recognize that the bear is present and is a threat to you,

69
00:04:09,929 --> 00:04:12,240
you experience the emotion of fear.

70
00:04:13,660 --> 00:04:17,190
Then, as a result of you experiencing the motion,

71
00:04:17,399 --> 00:04:19,399
you have a physical response.

72
00:04:19,410 --> 00:04:22,160
So, in your case, because you feel fear,

73
00:04:22,170 --> 00:04:25,040
your heart starts beating quickly and you start sweating.

74
00:04:25,529 --> 00:04:29,519
So, what do you think of Lazarus's Cognitive Mediational Theory?

75
00:04:29,529 --> 00:04:32,480
Do you think it's better than the others? Why or why not?

76
00:04:34,130 --> 00:04:35,470
So, let's review.

77
00:04:35,720 --> 00:04:39,140
The James-Lange theory of emotion suggests that emotions

78
00:04:39,149 --> 00:04:42,790
are caused by physiological responses to a stressor.

79
00:04:44,109 --> 00:04:46,980
The Canon-Bard theory of emotion suggests

80
00:04:46,989 --> 00:04:49,950
that you respond emotionally to a stressor,

81
00:04:50,029 --> 00:04:53,850
at the same time, the physiological changes in your body happen.

82
00:04:55,380 --> 00:05:00,410
The Schachter-Singer theory argues that after responding to a stressor,

83
00:05:00,459 --> 00:05:03,079
you appraise the threat at the same time

84
00:05:03,089 --> 00:05:05,760
as changes happen in your body such as sweating

85
00:05:05,929 --> 00:05:09,359
and increased heart rate, which leads you to feel the emotion.

86
00:05:10,470 --> 00:05:14,339
Lazarus's cognitive mediational theory argues that

87
00:05:14,350 --> 00:05:16,760
after being exposed to a stressor,

88
00:05:16,809 --> 00:05:20,170
you appraise the threat, then you feel the emotion,

89
00:05:20,299 --> 00:05:22,299
and then because you feel the emotion,

90
00:05:22,309 --> 00:05:27,140
you have a physiological response such as increased heart rate and sweating.
