10. Changes during Emotions

11. Physical Changes in Emotions
Facial expression: Each emotion has its definite
facial expressions. Various muscles of the face such
as the muscles of the eyes, nose, lips and forehead
undergo changes by twisting and twitching.
Muscular adjustments: Under certain emotional
expressions the muscles of the body make automatic
adjustments.

12. Contd…….
Voice changes: Voice also tells about the emotion of an
individual.
Releasing of energy: During emotions a lot of energy is
released to meet the emergency situation. Our liver
releases glycogen which gets converted into glucose and
it gets burnt releasing energy.
Respiration and circulation: In order to supply more
oxygen, lungs function faster and so breathing becomes
shallow and faster. Further there is an increased blood
pressure and heartbeats.

13. Contd….
Secretory Changes: There is a significant change in
various glands. The flow of these secretions in the form
of saliva, tears, sweats etc.
Changes in thermoregulation: There is a change in
temperature of the body. At the time of intense
excitement, it generally goes down.
Digestive changes: During emotions digestive system
gets affected. During emotional state our stomach and
intestines work quietly slow sometimes it increases the
function.

14. Contd…
 Other changes:
 Erection of hairs
 Stimulation of sweat glands
 Dryness of mouth
 Pupils become dilate
 Redness of the face
 Changes in body movements
 Blood clots more quickly in
case of wounds
Brain functioning
Emotion changes
our sensory and
perceptual
processes.

15. Psychological Changes in Emotions
During intense emotions our attention and
perceptual process get altered.
Our thinking and reasoning will be affected
adversely.
Learning will be slowed down during emotions.
Memory will be inhibited.
Disorientation of time, place and person may
experience during an intense emotion.

17. Theories of Emotion
Does your heart pound because you are
afraid... or are you afraid because you
feel your heart pounding?

18. James-Lange Theory of Emotion
This theory is proposed by William James and
Carl Lange.
 This is one of the best examples of
physiological theory of emotions.
James-Lange theory suggests that emotions
occur as a result of physiological reactions to
events.
For example: I see a snake “I am trembling,
therefore I am feared.”

19. James-Lange Theory of Emotion
Perception of an
Environmental Situation
Which Produces the Emotion
Physiological responses of
Body
Experienced Emotion

20. Cannon-Bard Theory of Emotion
This theory is proposed by Walter Cannon and
Philip Bard.
According to this theory, the emotional
experience and physiological experiences/ body
arousal both are independent of each other.
Both will be happening at the same time.

21. Cannon-Bard Theory of Emotion
Perceived Stimulus
Experienced Emotion Body Responses

22. Schachter- Singer / Two Factor Theory
Proposed by Stanley Schachter and Jerome Singer.
The emotional experience is a result of our cognitive
label or cognitive appraisal.
As a result of the cognitive appraisal of the situation and
body arousal we experience the emotion.
For example, if you experience a racing heart and
sweating palms during an exam, you will probably
identify the emotion as anxiety. If you experience the
same while seeing a snake, you might interpret as
fear.
