Emotions Flashcards
describe the James-Lange theory
describe the Cannon-Bard theory
describe the Schacther-Singer theory
summarize the 3 psychological theories of emotion
describe key phylogenic developments in the human brain
- atrophy of the olfactory syste
- expansion of the frontal and parietal lobes
- more flexibility in response than other animals
describe the Papez circuit
- cingulate - allows for mechanism of emotion
- belived that the hippocampus processed sensory info. and sends it to the int. thalamic nuclei (mammillary bodies) which then sends info. to the cingulate on “what is this?”
- the hypothalamus mediates physiological arousal, and would converge with the info. from the hippocampus in the cingulate and give rise to the emotional experience
contrast LeDoux’s high road vs low road theory
- low road = low-resolution visual info. straight to amygdala (byapasses primary visual cortex)
- high road = high-resolution info to cortex; slower
summarize the theorist and the advances they made in the limbic system
describe Kluver-Bucy syndrome
temporal lobe and amydala removed
- docility
- loss of fear
- hyperorality
- hyperphagia
- hypersexuality
- psychic blindness
- memory impairment
- aphpasia
- utilization behavior
- seizures
describe what these lesions can cause
Kluver-Bucy syndrome
contrast pre- and post- injury to the frontal lobe
Phineas Gage case demonstrated that ventromedial frontal lobes play a crtical role in behavioral monitoring and emotion regulation
- prior to frontal lobe injury
- polite
- socially well
- well adapted
- responsible capable
- post-injury
- erratic
- impatient
- irreverent
- emotionally expressive
summarize lesions of the limbic system
describe the formation of fear memory network
describe the formation of extinction memory
The old memory of tone + pain is NOT erased
A new memory of tone + no pain is formed through the ventromedial prefrontal cortex –> down-regulates amygdala
describe what is seen
