How can stressors be precieved
as dangerus- body prepares for immediate danger
As challenge- body bolsters a response that optimizes performance
(negative events produce more stress than positive ones)

- Selective negativity- focus on deficiencies and omitting the positives
What is neuroception and who started it
The relative capacity to evaluate danger and safety in ones environment
coined by Dr Porges
What is Porges theory of neuroception and 3 stages
The ANS regulates 3 fundamental physiological states when a threat is perceived
- Social engagement
- Fight or flight
- Shutting down
3 states in Porges theory and what happens in each
- Social engagement- calling out for support help etc
- fight or flight
- shut down- expend as lil energy as possible due to vagus nerve action
What is the ventral vagal complex and when does it dominate
Threats to our safety or social connections trigger changes in the areas innervated by the VVC
- can help result in calmness etc
When there is no way to fight or flight from a threat what gets activated and what does it do
dorsal vagal complex
-causes us to disengage, metabolic processes stop etc
In stressful situations what does the ANS do
- slowed or halted digestion
- increased HR, BP, CO
What is the ANS controlled by
hypothalmus
