L 9 Flashcards

animal personality
consistent across contexts
proactive vs reactive
pro: deal with challenge head on. low glucocorticoid stress response
- bury shock probe.
react: deal with challenge by avoiding. high glucocort stress response, run away from probe.
personality related to ?
how we perceive, respond, cope with stressors. – can affect risk for stress-related disease
primate personality: baboons in serengeti.
- what kind of stressors?
- social stress: have food, large social groups/interactions are stressful. competitive hierarchy also stressful.
measured glucocort, antibody and cholesterol male research bc females pregnant or w young
- baseline
- gary
kenneth
baseline: unstressed monkey, also done when stressed (post-fight, rejection to mating)
Gary: antagonistic way of dealing, threateningly, instigator. little social support = high stress hormones, low Ab levels, bad cholesterol profile.
Kenneth: calm, cool, didn’t start fights, played with offspring and groomed others. low stress hormones, , high AB, low cholesterol profile.
knowing wether threatening or neutral social encounter
- resting glucocort levels twice as high in males that cannot tell difference.
know when won encoutner
win = celebrate with grooming
lose = sulk or beat other guy.
sometimes react in same way = didnt know he won, didnt care => higher resting glucocort response.
behaviour upon losing a fight
hand by self
non-sexual grooming
beat up other guy = out let for frustration. lowest glucocort levels.
traits that lead to higher rank for longr
better physical health, less stress hormones, less insult on body, defend higher rank for longer
more time non-sexual grooming =?
lower glucocort levels.
high-reactor rhesus monkeys
shy, anxious, high glucocort levels, easily stressed in novel unstressful situation
.
genetic and enviro effects of high-reactivity
genetic: fathers personality
environment: if nurturing mother (direct physical contact) - high reactor status decreases.
two ways to end up with stress-related disease
mismatch btw magnitude of stressor and response
- do not utilize effective coping mechanisms
type A personality
- characteristics
- increase risk of?
competitive over-achieving, time-pressured, impatient, hostile.
cardiovascular disease. more than smoking/high cholesterol.
type A present before heart disease. type A => heart disease.
most significant factor btw type a and cardiovascular disease
hostility.
- males more likely to have heart disease than females.
- higher hostility = more heart disease than low hostility.
- other type a characters more heart disease than if don’t have other typeA characters.
best way to detect type A in interview?
look at body language.
hostility + social support = heart disease
expressing hostility
study: watch film on amputation. 1 - express emotion. 2 - cant express. 2= higher bp, indicators of stress. exacerbate physiology linked to that emotion
- hostile = suscpicious of others, higher bp when interrupted during timed math tests than non-hostile ppl.
- reduce hsotility = reduce cardiovascular effects
repressive personality -what is this?
dont subjectively believe they experience many stressors, but physiology tells a different story = chornically activated stress response.
- disciplined, enjoy structure and routine. lack emotional expression.
repressive personality + cognitive challenge
higher stress respones, dont like tests because cant predict or control.
represeive personality + frontal cortex
high activity = inhibitory on limbic system
repressive personality = hard work
hard to constantly remove ambiguity, control, predict.
3 c’s of hardiness
commitment
challenge
control
commitment of hardiness
sense of mening and purpose in life
challenge in hardiness
zest for life, see changes as exciting, not threatening
