1

What is meant by 'fight or flight'?

The bodys inbuilt response to stressful situations 

2

What is the purpose of the fight or flight response? 

Prepares the body to respond 

3

Name a study into the fight or flight response? 

Canon, 1932 

4

How does the fight or flight response prepare the body to respond to stressful situations? 

Short term changes mobilise for activity 

5

What is the fight or flight response triggered by? 

Mainly catecholamines 

6

What catecholamines trigger the fight or flight response? 

Adrenaline  Noradrenaline 
 

7

What does adrenaline do in the fight or flight response? 

Increases heart rate, so increases energy available in muscles 

8

What is the physiological response to stress? 

Increased oxygen availability Enhanced mental functioning  Increased fuel availability  Preparation for tissue damage/fatigue  Conservation of energy resources Enhanced physical functioning 
 

9

How is oxygen availability increased in stress? 

Increased respiratory rate Increased haematocrit 

10

What mental functions are enhanced in stress?

Sensory awareness Alertness
 

11

How is fuel availability increased in stress? 

Liberation of glucose  Protein breakdown  Insulin resistance 
 

12

Why does insulin resistance increase fuel availability? 

Because it increases blood sugar, so more fuel available for responses

13

How is the body prepared for tissue damage/fatigue in stress? 

Fluid conservation  Blood clotting Endogenous analgesia  Immune and inflammatory response 
 

14

How are energy resources conserved in stress? 

Non-essential systems such as the digestive system and sexual response are reduced

15

How is physical functioning enhanced in stress? 

Cardiac output  BP  Sweating Muscle responsiveness 
 

16

What effect does stress have on performance?

A bit of stress can improve performance to a point, but if too stressed, can be detrimental 

17

Why is too much stress detrimental to performance? 

It can make a person chaotic and disorganised 

18

What condition can be caused by long term stress? 

General adaptation syndrome 

19

When was General Adaptation syndrome discovered? 

In a study by Selye in 1956

20

What happens in General Adaptation Syndrome? 


Alarm induces fight or fight  Can't maintain this state Over days/weeks/months of stress, body is still performing at increased homeostatis levels, but body adapts, leading to resistance 

Resistance can't be maintained, leads to exhaustion 

Exhaustion is a state of physiological/psychological exhaustion  Can get initial stress symptoms again Chance of physiological damage and death 
 

21

What is the provlem with the stress response? 

Stress response is adapted for survival advantage, as hunter-gatherers are more likely to be exposed to acute stressores, however modern life has a change in sorts of stressors

22

What sorts of stressors are faced in everyday life? 

Frequent daily hassles and chronic stressors

23

What is the problem with the type of stressors faced in modern life? 

The physiological response is ill suited to long term stress

24

What are the limitations of a purely physiological model of stress? 

Individual differences  Context
 

25

How can individual differences and context affect stress? 

An individual may have different things that make something more or less stressful 

26

Who proposed the transitional model of stress? 

Lazarus and Folkman, 1984

27

How does the transitional model of stress define stress? 

As the perception of interaction with individual person and what's going on around them 

28

What does a person do in the transitonal model of stress? 

Demands Resources Constantly appraises this
 

29

What can demands be? 

Life events Daily hassles Chronic stressors 
 

30

Give two examples of life events that could cause stress

Illness Bereavement
