#6 u3aos1 - biological model of stress GAS (ch4c) Flashcards
General Adaptaton Syndrome (GAS)
3 marks
a biological model of stress that proposes we have a
non-specific response to stress
that occurs in three stages
characterisitics of GAS
3 marks
- non-specific
occurs regardless of the situation that is encountered - contains three stages
alarm reaction
resistance
exhaustion - physiological response
three stages of GAS
3 marks
alarm reaction
resistance
exhaustion
2 phases in alarm reaction
2 marks
shock
counter shock
alarm reaction
4 marks
the first stage of GAS
when the individual first becomes aware of the stressor
contains two phases
- shock
- counter shock
shock
2 marks
ability for the individual to cope goes below the normal level
of resistance against stress
counter shock
2 marks
sympathetic nervous system gets activated
the body’s ability to cope increases
above the normal level of resistance
resistance
3 marks
the second stage of GAS
where the body’s ability to cope with the stressor sustains at the max
as the
body prioritises functions to support this
what happens to the immune system during the resistance stage of GAS
2 marks
it gets weaker
as cortisol is relased excessively over a prolonged period of time.
exhaustion
4 marks
the final stage of GAS
the body’s resources will be depleted as it has been
suppying the individual for a prolonged period of time
this leads to the immune system being left impaired
which stage of GAS is cortisol released?
1 mark
cortisol is released through all stages of GAS
explanatory power
1 mark
the ability of a theory/model to explain subject matter effectively
