quiz 5 - emotion Flashcards
(15 cards)
what are Ekman’s criteria for basic emotions
- distinctive universal signals
- presence in other primates
- distinctive physiology
- distinctive universals
- rapid onset
- brief duration
- automatic appraisal
- unbidden occurance
implicit vs explicit fear locations
implicit occurs in bilateral amygdala
explicit occurs in the hippocampus
what happens in fear learning when damage happens to the bilateral amygdala
patient shows UCR to upcoming shock but fails to develop CR (even though they are fully aware that there is an association between cue and shock)
= NO LEARNED FEAR
how to measure fear
physiologically = SCR/ECG
behaviorally = startle behavior/freezing behavior
what structures are involved in Papez’s circuit
cingulate gyrus –> PHC –> subuculum (hippocampus) –> mamillary bodies –> anterior thalamic nucleus
what were the results of the Schacter/Singer epinephrine study & its implcations
confederate behavior influenced participant’s emotional
- informed participants had no change in emotion state
- ignorant and misinformed participants had manipulated emotional states
implications: physiological change/arousal are not enough to explain/dictate emotions, have to look at surroundings
what is the amygdala, and what are two major subdivisions + their functions
- major hub, collection of nuclei, not monolithic structure
- basal lateral nuclei receives incoming signals, processes & evaluates them before placing emotional significance to it
- central nucleus serves as output center and coordinates projections
what are the results of the iowa gambling tasks in healthy versus amygdala/PFC lesioned patients
healthy = anticipatory SCR response, learned in as little as 10 picks
patients = do not show learned response & continues to select from ‘bad; decks even after healthy patients had abandoned them
what does OFC lesion do (according to iowa gambling task)
causes insensitivity to future consequences
Cannon-Bard theory of emotion
physiological/behavioral changes are not directly linked - parallel processing is mediated by the thalamus & emotional feelings
- emotions can happen even if body feedback is disrupted, and different emotions can produce similar body responses
James-Lange theory of emotion
emotion is the experience of bodily arousal, somatic/autonomic physiological change
amount of evidence for basic negative emotions
shame = least evidence
fear/anger = most (strong) physiological evidence
sadness = moderate evidence
what was the result of patient SP’s bilateral amygdala damage
showed UCR but no CR developed
what did Darwin say about the purpose of facial expressions in emotion
proposed that facial expression provides a window into emotional experience (=communication), either:
- in relation to underlying emotion
- as an opposite of another emotion
- as an involuntary response
what did Duchenne de Boulogne argue
emotions have no function - “no mechanical necessity”
