emotion Flashcards
categories of emotion
basic emotions
complex emotions
basic emotions
Unique characteristic.
Developed through evolution.
Reflected in facial expressions.
complex emotions
Combinations of basic emotions.
May be socially or culturally learned.
theories of emotion generation
cannon-bard theory
james-lange theory
LeDoux - two emotion systems
james-lang theory
stimulus > physiological reaction > automatic nonconscious interpretation of physiological response
cannon-bard theory
James must be wrong because physiological signals can be interpreted in different ways – e.g. sweating = anxiety or excitement.
Neuronal and hormonal feedback processes also too slow to account for speed with emotions experienced.
Proposed sympathetic nervous system coordinates behavioral reaction while cortex simultaneously generates the ‘feeling’.
Suggests physical reactions and conscious experience of emotion completely independent.
Emphasized role of thalamus in emotion.
LeDoux – two emotion systems
One system for emotional responses.
Another system for generating the conscious feeling of emotion.
First system evolved to produce fast, automatic responses.
Second system produces feelings, which are learned by experience.
Low road
Fast
Unconscious
Immediate response – run away.
High road
Slow
Conscious response – full sensory analyses of threat.
pre amygdala lesion
rat had fearful response
post amygdala lesion
rat had no fear
Role of amygdala in learning and memory
Amygdala necessary for learning association between stimuli and threat.
Amygdala necessary for implicit learning but can also play a role in explicit learning under some conditions.
Amygdala acts to modulate hippocampal consolidation for arousing emotional events.
insular cortex
interoception, disgust
Interrogating emotional (body state) information with cognitive factors.
orbitofrontal cortex
reward, inhibition of previously learned associations, using subjective states as outcomes of decisions to guide future responding.
