Aspects of Emotion
![Page 4: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/4.jpg)
Components of Emotion
Cognitive component • subjective conscious feelings—thoughts,
values and expectations
![Page 5: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/5.jpg)
Components of Emotion
Physiological (arousal) component • controlled by certain brain structures and
autonomic nervous system
![Page 6: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/6.jpg)

Components of Emotion
Behavioural component (emotional expression—facial expressions,
gestures, body position, use of eye gaze, touch and tone of voice)
![Page 8: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/8.jpg)
• Why do we feel emotion?• What purpose does it serve?• Are humans the only animals that feel
emotion?• How many emotions are there?
![Page 9: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/9.jpg)
James-Lange Theory
• A stimulus directly produces physiological changes and behavior, and then these events produce the feeling of an emotion.

James-Lange Theory
• Smiling makes you feel happy• Crying makes you feel sad

Facial Feedback Hypothesis
• Facial feedback is interpreted by the brain as being a certain emotion.
• Once an emotion is activated, the whole body becomes aroused.
• Arousal and external stimuli maintain the emotion after facial feedback initiates it.

Passive Facial Feedback Participants and apparatus (do not note)
One hundred and eight-nine Japanese undergraduates (101 males and 88 females) participated.
One hundred and thirteen were assigned to the experimental condition, and 76 to the control condition.
Small plastic pipettes and warmed water were used.
![Page 20: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/20.jpg)
Method
Water dripped on the participants cheeks or temples.
Then, the raters rated their subjective emotion on a seven point scale.

Sad Neutral Cheerful Mixed
CheeksTemples
Water dropping on the cheeks tended to cause the sad emotion more often than the cheerfulness.

Cannon-Bard Theory
Theory in which the physiological reaction and the emotion occur at the same time.
Stimulus
Emotion
Physiological Response

Theory of Cognitive Appraisal
(Schachter-Singer 2 factor theory of emotion)A two-stage theory stating that for an
emotion to occur, there must be 1.physiological arousal and 2.an explanation for the arousal
![Page 24: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/24.jpg)
Two key variables manipulated-1. Arousal 2. Emotional Explanation for the Arousal were the two
• Participants injected with “suproxin”– Placebo or Epinephrine– Participants either informed or misinformed about the
effects of the drug
• Confederate acted angry or euphoric
Schachter and Singer (1962)Experiment
![Page 25: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/25.jpg)

Epinephrine uninformed more angry/happy than informed because they attributed their arousal (which was drug induced) to the situation.
• Implication:Emotions are somewhat arbitrary, depending on
what the most plausible explanation for the arousal happens to be.

Evaluation of Emotion Theories
Emotional responses vary more than any one theory allows depending on the situation.
Currently no emotional theory is accepted as completely correct .

Three Ways to Measure Emotion
1. Body/Physical
2. Thoughts
3. Behavior
![Page 29: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/29.jpg)
Culture and Emotional Expression
Basic emotions are similar
Social rules about display of emotions vary from culture to culture eg Japanese vs Italian
![Page 30: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/30.jpg)
Three Ways to Measure Emotion• Body/Physical
– blood pressure
– heart rate
– epinephrine levels
– muscle activity when smiling, frowning, etc.
– neural images
– posture
– tears,
– perspiration
– lie detector readings
![Page 31: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/31.jpg)
Three Ways to Measure Emotion• Thoughts (observed indirectly through)
– spoken and written words on rating scales
– answers to open-ended questions on surveys and during interviews
– self-assessments or perceptions regarding the behavior and intentions of others
– other cognitive operations such as rational/logical thinking
![Page 32: Emotion annesley 2010](https://reader035.vdocuments.mx/reader035/viewer/2022062418/5550dfa9b4c905417d8b467f/html5/thumbnails/32.jpg)
Three Ways to Measure Emotion• Behavior
– facial expressions
– activity level
– alertness
– screaming
– laughing
– smiling
– aggression
– approach/avoidance
– attention/distraction
– insomnia

Ethical Issues of Polygraphs
• Lie detectors only 75% reliable• Some people better at hiding facial/body
expression of emotion

Overview of General Theories of Emotion
• James-Lange Theory (arousal and expression produce emotion)
• ii. Cannon-Bard Theory (cognitions, arousal and expression are simultaneous)
• iii. Facial-Feedback Hypothesis (expression produces emotion)
• iv. Schachter’s Two-Factor Theory (emotions depend on 2 factors—physical arousal and cognitive labelling of that arousal)
