HYS - CH5: Motivation, Emotion, Stress Flashcards
universal emotions
surprise, fear, contempt, disgust, anger, happiness, sadness
same way across all cultures
James Lange Theory of emotions
you see a bear
detect a bear in brain activates sympathetic
(not consciouly afraid)
heard pounds
then conscious fear
physiological changes spark psychological ones (emotion starts in your body)
Walter Cannon and Bard theory of emotions
problem with james lange: heart pounding could mean, fear, love, jogging when same set of changes are associated with many emotions or none
conscious expierence and physiological changes are seperate and simoltaneous events
who came up with fight or flight
Cannon
thalamus
relays to cortex for thinking
relays to the body for physiological changes
thalamus is a part of what system
limbic system
thalamus communicates physiolgical changes to upper cortex
amygdala - fear, anger, agression
septal nuclei - dopaminergic reward
hippocampus - memory
Schacter Singer theory or emotion - cognitive appraisal
environmental cues to help assign emotional states
butterflies - excited when seeing a crush
butterflies - nervous about a test
this allows for unconscious labling of physiological state so multiple physiological changes can be differently pyschologicall labeled
which theory of emotion is most commonly accepted
schacter-singer: cognitive appraisal is used to distinquish between emotional states
which theory is associated with thalamus?
cannon-bard
eustress and distress
distress - neg
eustress - pos
cognitive appraisal has 2 stages (primary and secondary appraisal):
primary appraisal
determines if situation is of concern: benign or threat
based on past history/thoughts and feelings
is the event stressful?
secondary appraisal
- did the event cause harm
- can it be overcome
- will it cause future harm
chooses a course of action
external and internal events in stress response
external - bear
internal - primary and secondary appraisal events
types of stressed
inclement weather, hot, cold, loud sounds, noises
challenges with time, social pressure, peer pressure, expectations, sleep, diet, alcohol, drug use, allergies, conditions
emotional responses, controls, internal expectations
stages of stress response
alarm - bear occurence first time
resistance - bear comes again
exhaustion - chronic stress as bear is always around them
alarm response hormone pathways in acute response pathways of the general adaptation syndrome
hypothalamus (control system)
–> adrenal glands
–> epinephrine and norepinephrine
hypothalamus
–> CRH acts on pituitary gland
–> pit gland releases adrenocorticotrophin hromne (Acth) which stim adrenal glands
–> adrenal glands release cortisol
epinephrine and norepinephrine
increase heart and resp, stim glycogen breakdown, releases sugar in bloodstream, directs blood flow to heart, lungs, brain muscles
cortisol
raises blood sugar, amino acids, fatty acids, decreases inflammation
happens slower
prepares for physical activity
is pain a universal facial expression
no
what happens to blood flow and skin temperature in stress response
blood flow to skin decreases as blood is directed to other muscles and other organs in the fight or flight response
decrease in skin temperature
reappraisal
contant reevaluation of an ongoing stressful situation
what part of appraisal invovles if a stressful event can result in future benefit
secondary – evaluating challenge and if it can be overcome or beneficical
NOT primary– is the event stressful?
hormones in general adaptation syndrome created by Hans Selye?
cortisol (adrenal cortex stimulated to secrete this)
ACTH (hypo–> pit–> acth)
epinephrine and norephinephrine (hypothalamus –> adrenal)
what determines if a stressor will result in eustress or distress?
if person expierencing stressor percieves it as pos or neg
