Ch12-Emotional Behaviors Flashcards
emotion is typically defined in terms of what 3 components?
cognitions, feelings, actions
emotions lead to arousal in the _______ branch and the _______ branch of the autonomic nervous system
sympathetic; parasympathetic
theory that states autonomic arousal & skeletal actions come first
James-Lange theory
order of emotion as defined by James-Lange theory
event -> appraisal (cognition) -> action -> emotional feeling
two predictions of James-Lange theory
1) people with weak autonomic or skeletal responses should feel less emotion
2) causing or increasing someone’s responses should enhance an emotion (ex: happier when smiling)
theory that states subjective experience of emotion & the associated body reactions are independent processes
Cannon-Bard theory
theory that states the cognitive interpretation [appraisal] of a body reaction drives the subjective experience of emotion [interpretation of arousal determines subjective emotion]
Two-Factor theory
output from the autonomic nervous system to the body fails completely or almost completely
[report same emotions, but feel them less intensely]
pure autonomic failure
marked by extreme sympathetic nervous system arousal
panic attack
syndrome characterized by people being unable to move their facial muscles to make a smile, but they still experience happiness
Mobius syndrome
forebrain areas surrounding the thalamus; regarded as critical for emotion
limbic system
the only emotion for which brain evidence suggests brain localization is ______
disgust
______ cortex is strongly activated if you see a disgusting picture or facial expression of someone feeling disgusted
insula [primary taste cortex]
activity of the left hemisphere [frontal & temporal lobes] marked by low to moderate autonomic arousal & a tendency to approach [happiness or anger]
behavioral activation system [BAS]
increased activity of right hemisphere [frontal & temporal lobes] that increases attention & arousal, inhibits action, & stimulates emotions such as fear & disgust [withdrawal behaviors]
behavioral inhibition system [BIS]
differences between hemispheres relates to personality:
- people with greater activity in frontal cortex of left hemisphere are ________
- people with greater activity in right hemisphere are _______
- happier and more outgoing;
- socially withdrawn, less satisfied with life, and prone to unpleasant emotions
right hemisphere appears to be more responsive to _________ than the left
emotional stimuli
damage to right temporal cortex leads to _______
trouble identifying emotional expressions
patients had one hemisphere at a time anesthetized; this is called the _____ procedure
Wada procedure
emotions are useful for ______
adaptive values [escape; attack]
quick decisions [gut feeling]
moral decisions
damage to prefrontal cortex leads to ______
failure to anticipate unpleasant outcomes; make impulsive decisions
case of Phineas Gage
iron rod through prefrontal cortex; behavior became impulsive, made poor decisions
Damasio’s patient with prefrontal cortex damage expressed almost no ______
emotion
example of vigorous emotional behaviors we observe in animals that falls into categories of attack & escape
cat & mouse play
_____ behaviors are associated within the corticomedial area of the amygdala
attack
likely environmental factors underlying violence:
exposure to lead
witness or victim of violence in childhood
living in violent neighborhood
violence is particularly enhanced in people with both a ______ predisposition and troubled early ______
genetic; environment
effect of ______ gene apparently interacts with childhood experience
MAOA [monoamine oxidase A]
evidence links aggressive behavior to high levels of ______ and low _______ release
testosterone; serotonin
Valzelli found that isolating male mice for 4 weeks increased their ______ behavior & decreased their serotonin ______
aggressive; turnover
the amount that neurons release & replace
turnover
