G.A.S Flashcards
What is selyes GAS?
A biological model involving 3 stages of physiological reactions
What are the 2 elements for describing GAS?
- Non specific
- Identical within all members of a species
Define alarm reaction
The first stage of GAS, initial decrease and subsequent increase in bodily arousal
What happens during shock? (sub.1 alarm)
- decreased bodily arousal for a brief period of time following initial response to a stressor
- The body reacts as if it has been injured; biological processes within the body fall below normal functioning
- The ability to deal with the stressor is reduced below normal
What happens during counter shock? (Sub.2 alarm)
- The sympathetic nervous system responses occur and causes physiological sensations to occur
- The level of bodily arousal & ability to deal with stressor temporarily increases above normal
What happens during resistance (2nd stage of gas)?
High levels of bodily arousal, cortisol levels increase to maintain heightened physiological state; this state is adaptive and adjusts to physiological changes that occur during counter shock.
What happens during exhaustion (3rd stage of gas)?
Energy & bodily resources are depleted, inability to cope with stressor; become vulnerable to physiological & psychological illnesses
