Social Psychology Lecture 11
-Stress: a response you have to a demanding situation (the stressor)
-stressors can take diff forms: can be psychological, or physiological (staying up all
night to study)
-psycho stress: degree to which you have to adapt in order to respond to an event
that requires you to change and readjust your life
>good and bad events are stressful, anything that requires change (marriage,
graduation, death in the family)
-physio stress: body responds to maintain homeostasis. when body comes out of its
normal routine to respond to something
-allostasis: a tight allostatic system, very flexible (highs to lows) in terms of arousal.
all for the purpose of adapting to the current environment
>when we're chronically stressed, you see allostatic load (when body stress
system is continuously activated) and you don't have time to recover between
stressors. system maintains a high level of stress for long time and body is less able
to flexibly adapt
-result of chronic stressors is that if you have allostatic stress, its related to heart
diseases, diabetes, cancer, immune disease
-challenge is the good stress, improves your performance. threat inhibits your
performance
-only see challenge and threat when you're in a situations where you're motivated
to perform well (e.x going to write an exam)
-in both challenge and threat theres an increase in heart rate, you're aroused.
-challenge: heart beats with greater strength
-challenge or threat? how you appraise cognitively the current situation
-your perception of the demands of the situation compared to your perceptions of
the resources you have to meet he demands
>challenge: you can meet every demand. threat: psychologically you think your
resources are less then you need to meet the demands
-psycho stress decreases immunity, makes your more susceptible to disease
-stress on long term health, allostatic load (stress system is not flexibly responding,
constantly activated. higher levels of cortisol)
-chronic stress is bad for your body, predicts high blood pressure, type II diabetes,
heart problems
-stress can also be good, sometimes leads to thriving
-people who have stress but respond in a thriving way are stronger, happier, and
more able to deal with future stressors
-you get acute, repeated stressors but you have time to recover in between stressors.
-compared to no stress or chronic stress, people who relax in between each stressor
are more able to cope with subsequent stressors and they have a healthier immune
system and longer cell life
