1

What is stress?

Your mind and body's perception of and reaction to a real or imagined stimulus and its ability to cope with this stimulus

2

What are the 3 main models of stress?

Stimulus

Response

Transactional

3

Describe the Stimulus model of stress

Stress is something that occurs in the environment

A stressor i.e. a stimulus that causes stress

Treatment = remove/avoid the source of stress

4

Describe the Response model of stress

Stress is something that occurs within the organism itself

Stressor is unimportant, the degree of readjustment is what is important

Treatment = control symptoms of stress (yoga, relaxation)

5

Describe the Transactional model of stress

Stress is a transaction between the organism & its environment

Stress occurs when the organism is unable to cope with the environment

Treatment focuses on methods of coping with stress

6

Describe the stress response

Alarm phase
- experience of a stressful event or perceiving something as stressful

Resistance
- attempting to cope with or adapt to the stressful stimulus
- involves physical or mental exertion

Exhaustion
- stress not being managed effectively
- body and mind are not able to repair damage
- leads to chronic stress

7

Describe the initial detection of stress

Stress stimuli initially detected by the cerebral cortex =>

activation of the sympathetic system =>

prepare the body for physical activity

8

How does the sympathetic system deal with stress?

Short term response
- activation of sympathoadrenomedullary axis
=> leads to release of nor/adrenaline

Long term response
- activation of the hyp-pituitary-adre axis
=> CRH release -> ACTH release -> corticosteroids release

9

How is the amygdala involved in stress?

Modulates stress response mechanisms
- esp. when fear and anxiety are involved

10

How is the hippocampus involved in stress?

Plays important role in memory formation

Memory can enhance, suppress or generate a stress response

Cortisol release can damage hippocampal cells during chronic stress

11

What are the different types of stress?

Eustress = good stress - to improve performance

Distress = bad stress - stress response too high

12

What is cognitive appraisal?

Allows the stress to be taken into context
- i.e. tiger in zoo behind bars not as stressful as out in wild

13

What is learned helplessness?

When control is taken away from us => feel helpless at avoiding stressful stimuli

Don't escape from the stress once control given back
- i.e. just put up with it, even though it can be dealth with

14

What are the three main types of stress decision making?

Approach-approach
- decision between two positive options

Avoidance-avoidance

Approach-avoidance
- options have both positive and negative options

15

Two types of personalities when dealing with stress

Type A = ambitious, highly status conscious, "workaholics"
- most vulnerable to stress

Type B = opposite to type A

16

Which three factors increase motivation?

Autonomy
