ch 20 - emotion Flashcards
what are emotions?
a subjective response to a situation
what are the 2 dimensions of emotion
pleasant-unpleasant
arousing-nonarousing
EXAMPLES
High arousal, pleasant: Excitement, joy, elation (intense positive feelings)
High arousal, unpleasant: Anger, fear, anxiety (intense negative feelings)
Low arousal, pleasant: Contentment, calm, serenity (low intensity, positive feelings)
Low arousal, unpleasant: Sadness, boredom, depression (low intensity, negative feelings)
what are two important areas involved in emotion
frontal lobe (lobotamy)
amygdala (fear)
what are some stimuli that animals use to express emotion to each other (communicating)
cats and other mamals release odors and have receptors that detect certain kinds
humans use facial expressions
How does the limbic system involve emotion
Cingulate cotext send info to —–>
hippocampus, orbitofrontal cortex*, amygdala
then this info is sent to the PFC and Hypothalamus –> pituitary gland to be analyzed and hormones produced
**orbitofrontal cortex is for most emotion regarding stiumlus=reward
what is the limbic system
network for emotion, behaviours and motivations
less popular theory of emotion regarding the hemispheres
left = fear, negative emotions
right = apathy, all emotions
posterior = where facial expressions are made
not a good theory. inconsistent results
where would you put a lesion to make someones not understand humor
right frontal lobe (emotion dominating)
where would you put a lesion to make someone not recognize facial expressions and context
left frontal lobe (context dominating)
also left temporal lobe
what characterizes a patient with temporal lobe epilepsy
humourless, emotionless, obsessed
what is allostasis
maintaining internal stability despite changing conditions (controlled by executive network)
what is LeDoux’s theory of Emotional Consciousness
conscious emotion happens in one circuit
motion alarm (fast amygdala) —> whats that
security cam (slow frontal cortex) —> just my cat
you in you house (consciousness) –> emotion relief
how do we supress pain during fear conditioning
once you learn to expect the pain, you amygdala activates your autonomic nervous system and suppresses that pain in anticipation
what are the 4 networks of the social brain?
- amygdala network - detects relevant social info
- orbitofrontal cortex
- amygdala - mentalizing network - anaylzing a person
- Superior sulcus
- medial frontal network - empathy network - empathy
- insula
- cingulate cortex - mirror/action-perception network - self-perception
- mirror neurons in parietal and
pre-motor cortex’s
- cortical frontal network
- right frontopariental network (your face in mirror)
