Document Summary

There are diverse stress pathways many regions of the brain are involved in feedback loops that can amplify the stress response. I(cid:374)di(cid:448)idual"s per(cid:272)eptio(cid:374) of stressor is i(cid:373)porta(cid:374)t + affe(cid:272)ts their stress respo(cid:374)se. Primary appraisal is assessing stressor as important yet potentially demanding. Secondary appraisal is assessing resources to deal with stressor may need to revise primary appraisal: perception of control also affects stress response, stressor that seems easy to handle active coping mechanisms = Norepinephrine release: stressor seems more difficult to handle more anxiety passive coping mechanisms = epinephrine release, stressor seems even more uncontrollable increase in distress = It boosts feel-good endorphins and distracts you from daily worries: cardiovascular measurement = usually use hr and bp responses very consistent.
