Bio Psych lecture 7 Flashcards
6 primary emotions
suprise, fear, anger, disgust, happiness, sadness
->Additional contempt and emberassment/shame.
Neurocultural Theory of Emotion
emotions are shaped by cultural and biological processes.
Polygaval Theory
-Responding to threat by reducing metabolic activity by immobilization behaviors.
-then increasing metabolic activity for neccesary fight-or-flight behaviors.
-then cranial nerves regulate facial expressions and vocalization.
-quick changes in the body to support engagement with the environment.
Response to traumatic stress phases
-Freeze. searching for environmental source of threat
-Flight. avoid conflict.
-Flight. if cant avoid conflict, activation of sympathetic nervous system.
-Fright- toxic immobility. like playing dead.
-Flag. shutdown of activity and drop in blodd pressurdd.
-Fainting
Pseudo-Neurological Symptoms
-physical symptoms without a physical cause/origin.
Facial Nerves
-Superficial
-Deep
-superficial nerves control our facial expressions.
-deep nerves attach to bone, enable large movements like chewing.
Face Muscles are controlled by 2 cranial nerves;
-Facial Nerve
-Trigeminal Nerve
Facial Feedback Hypothesis
-facial expressions affect our emotional experience.
Social and emotional processing is impaired in alcoholics (in right hemisphere and frontal lobes)
Alcoholcs makes mistakes especially identifying anger and disgust.
They overestimate the insensity of emotions.
James-Lange Theory of Emotion
-an percieved emotional stimuli leads to set of physiological responses, then determine the emotion experienced.
Critisim
-interruption of physical feedback may limit the intensity it felt.
-same visceral changes (internal organs that are not very sensitive) occur in different emotional states and also non-emotional states.
-Visceral changes are too slow to be the source of emotional feeling.
-like increasing heart rate doesn’t neccesarily result in a genunie emotional experience.
Cannon-Bard Theory of Emotion
-emotional and physiological response occurs simultioneosly.
Schacter’s Cognitive Labling Theory of Emotion
-how we interpret a situation plays a role in emotion we experience.
(knowing ur heart is racing cuz of caffeine, u wont attribute it to external situation.)
Somatic Market Hypothesis
physiological responses directly affect areas involved in decision making.
Papez Circuit
-The Cortical Circuit
-The Thalamic Circuit
-expression of emotion.
-cortical circuit-thinking or perception of emotion.
Kluver-Bucy Syndrome
-monkeys that would act aggresively before didnt now.
-due to changes in papez circuit.
-amygdala can account for reduction in fear responses.
Amygdala integrates info from both cortical and subcortical brain regions.
Amygdala has 2 Routes
1-direct projection to hypothalamus which carries sensory info and can activate body systems without consciouss awarness.
2-a conscious route where feeling of emotion is experienced.
Damage to amygdala
-impacts ability to recognize negative facial expressions.
Leisons in hippocampus
-prevent contextual fear-conditioning.
Global Organismic States
-organisms overall physiological and emotional conditions rather than focusing on the isolated ones.
Conceptual Model of Emotion
-Primitive Psychological Processes
-Core Effect
-emotions depends on context and culture, not biology.
-primitve psyhc…-not spesific to emotion, general processes for mental life.
-core effect-mental representations of bodily sensations that inform the organism smth in the environment is important.
Barret’s Conceptualization
-Valence]
-Arousal
-valence-unpleasant to pleasant
-arousalp-low to high
-how emotions vary based on these dimensions.
