4C - GAS model

Question 1

fight / flight response is part of which division?

Answer 1

the sympathtic division of the autonomic nervous system

Question 2

what is the freeze response activited by?

Answer 2

the parasympathetic system

Question 3

what are some of the physiological changes that occur when the parasympathetic nervous system dominates?

Answer 3

disassociation
numbness
shut down
low energy

Question 4

what are the 3 stages of the GAS model

Answer 4

1. Alarm Reaction
2. Resistance
3. Exhastion

Question 5

what are the 2 sub divisions in alarm reaction

Answer 5

shock & countershock

Question 6

what happens in shock (4)

Answer 6

• body acts as if its injured
• biological reactions fall below regular functioning
• blood pressure and tempreture drops
• freeze response occurs

Question 7

what happens in countershock (3)

Answer 7

• sympathetic NS becomes dominant (fight or flight)
• moblises body to respond to the stressor
• stress hormones are released (adreneline & cortisol)

Question 8

what happens in resistance stage? (4)

Answer 8

• body adapts to persistance stress
• cortisol levels are increased
• immune system is supressed
• minor illnesses start to occur

Question 9

what happens in exhastion (3)

Answer 9

• cortisol resources become depleted
• serious illnesses start to occur
• levels of resistance drop below normal levels

Question 10

explanatory power of the GAS model. one strength and one limitation.

Answer 10

strength
- the model suggests a predicatable pattern of responses can easily be tested in a labratory

limitation
- does not account for individual differences in stress responses.
