1

Major Theories of Emotion

James-Lange, Cannon-Bard, Lazarus Cognitive, Appraisal, Shachter-Two Factor

2

James Lange

body sensation then emotion

3

Cannon Bard Theory

body sensation and emotion - same time

4

Lazarus Cognitive Appraisal - primary/secondary/reappraisal

emotions are universal - but difference in how interpreted. if you think its bad - emotions follow and vice versa.
Primary - evaluation of situation
Secondary - evaluation of resources
Reappraisal - monitors and adjusts if necessary

5

Brain mechanisms involved

cerebral cortex, amygdala, hypothalamus

6

cerebral cortex

left side - governs happiness, and positive emotions = damage severe depression, anxiety, aggression
right side - mediates sadness, fear, and damage is indifference apathy, emotional lability/undue cheerfulness and joking

7

amygdala

attaches emotion to memory - evaluates incomoing senory infor and mediates response.

8

hypothalamus

translates emotions into physical response

9

General Adaptation Syndrome

mediated by adrenal and pituitary glands :alarm, resistance, exhaustion

10

chronic stress - affect on health

lowers resistence to disease. Prolonged sress is attributable to elevated levels of corticosteroids which compromise the immune system by decreasing T cells and lowering immune defences

11

Allostatic Load Model
only amygdala, hippocampus and prefrontal cortex in this model

takes the person into consideration - “the brain is the key organ of stress … because it determines what is threatening and therefore stressful, and also determines the physiological and behavioral responses [to stress]

12

allostatis

process by which the body can adapt to change from stress

13

allostatic state

can be maintained for a while as body adjusts

14

allostatic overload

adverse affect on mental and physical health. the nature of allostasis and consequences of allostatic load vary from person to person due to several factors, including differences in genetic makeup, resilience, and perceptions about the controllability of the stressor.

15

Schachter's Two Factor Theory

experience of emotion to physiological arousal followed by assigning a cognitive label to that arousal - cogntive interpretation of event
