Chapter 10 Emotions Flashcards
What is an emotion? 3 components?
-responses that vary in “goodness” to external stimuli and/or internal mental representations
- physiological reaction (rapid heart beat)
- behavioral response (smiling)
- a feeling
list 10 basic emotions (as defined by Izard)
- Joy
- Surprise
- Sadness
- Anger
- Disgust
- Fear
- Contempt
- Shame
- Guilt
- Interest- excitement
James-Lange theory of emotion
-physiological arousal comes before emotion
stimulus –> physiological response –> behavioral response —. cognition –> subjective emotional feeling
ex: see bear –> adrenaline, heart beat—> run —> interpret physiological response –> I’m scared
Cannon-Bard theory of emotion
-physiological arousal and emotion happen at the same time
stimulus –> cortex (feeling) AND hypothalamus, physiological response, behavioral response
ex: bear —> I’m scared AND sympathetic nervous system, racing heart beat, fight or flight, run
two-factor theory
- emotions have 2 ingredients: physical arousal and cognitive appraisal
- thinking contributes to feeling
- sees bear—> physiological response (arousal)—> behavioral response —>cognition –>run
ex: walking down alley, hear noise, know is a bad place = leads to feeling of fear
High road theory (Lazarus)
- thinking before feeling (complex)
- emotions arise when we appease an event as harmless or dangerous
- cognition (quick risk-benefit appraisal) –> emotional feeling –> behavioral response
ex: sees bear—>evaluate (risk is high, and there’s no benefit)—> I am in danger –> I’m scared—> runs
low road theory (LeDoux)
- feeling before thinking (simple)
- feeling something w/out knowing why
- instant emotional reactions apart from cognitive appraisal
stimulus —> slow cognition (emotional feeling) OR fast cognition (defensive behavior)
sees bear–? slow (I’m scared) OR fast (run)
describe the lesion and deficits of patient S.M.
- bilateral amygdala atrophy
- unable to identify fear in faces and has a selective reduced experience of fear (unable to avoid dangerous situations)
-can recognize other emotions, BUT if S.M. looks at the eyes she can recognize fear
where is the lesion located in human patients with Kluver-Bucy syndrome …….symptoms
-location: amygdala
-symptoms: Docility (loss of fear and anger responses);
Hyperorality (Like to put random things in their mouths); Dietary changes; Visual agnosia; Amnesia; Hypersexuality
how is the amygdala involved in implicit memory
- Amygdala is critical for the acquisition and expression of an implicitly conditioned fear response
- ex: a memory we have learned personally
how is the amygdala involved in explicit memory
- Amygdala is also necessary for normal indirect emotional responses to stimuli whose emotional properties are learned explicitly
- Amygdala can enhance the strength of explicit memories for emotional events by modulating storage
Ex: if neighbor tells us a dog is dangerous in our neighborhood= we become afraid of that dog based on what we learned explicitly
how is the amygdala involved in decision making
damage to amygdala causes difficulty with decision making
how is the orbitofrontal cortex involved in decision making
Patients with orbitofrontal cortex (OFC) damage have trouble anticipating consequences of their actions and learning from mistakes (and therefore decision
making)
-emotion regulation
name all the emotional processes that the amygdala has been shown to be involved in
- recognition of fearful faces and fear
- categorizing people into groups
- implicit and explicit emotional learning
- decision making
- attention
- perception
- social interactions (eyes)
how is the insula involved in emotional processing
–body information central
- Necessary to be aware of our body states to experience emotion
- Lesions associated with reduced arousal and reduced valence (positive/negative)
- May be particularly import in DISGUST
- Involved in integrating physiological reaction with our cognitive state of feeling
