5.2 Emotion Flashcards
What are the 3 elements of emotions?
physiological response, behavioural response, cognitive response
What is the cognitive component of emotion?
mental assessments that can include thoughts and assessments of situation (vary from person to person)
cognitive experiences can both result from emotions or cause emotions
What are the 6 universal emotions?
ALL humans have the same set of facial expressions for these 6 emotions:
- happiness
- sadness
- surprise
- fear
- disgust
- anger
note: there are cultural dissimilarities in emotion such as varying reactions to similar events, the emotional experience itself, etc.
What is the James-Lange theory of emotion?
the experience of emotion is due to the physiological response
stimulus → physiological response → emotion
(you’re not crying because you’re sad, you’re sad because you’re crying)
What is the Cannon-Bard theory of emotion?
physiological experiences and emotion occur simultaneously
stimulus → physiological response + emotion
(due to the observation that many events have the same physiological responses but different emotions attached)
What is the Schachter-Singer theory of emotion?
stimulus → physiological response + the cognitive interpretation of response → emotion
What is the Lazarus theory of emotion?
the experience of emotion depends upon how the situation is appraised (labelled)
stimulus → cognitive labelling/interpretation of event → physiological response + emotion
(how we label events varies based upon cultural/individual differences)
What is the limbic system and which structures does it include (4) ?
a set of structures in the brain responsible for storage/retrieval of memories, especially ones tied to emotions (serves as control for basic emotion and drives/motivation)
hippocampus, hypothalamus, amygdala, thalamus,
mnemonic: Hippo wearing a HAT
What is the role of the thalamus in the limbic system?
“sensory relay station”
- everything you hear/taste/etc. ends up in thalamus, which directs these senses to the appropriate areas in cortex.
- sensory input affects emotions
- smell is the only sense that bypasses the thalamus; goes to areas closer to amygdala (smell is strongly associated with memories)
What is the role of the amygdala in the limbic system?
involved in emotions such as fear/anger (aka “aggression center”)
stimulation = anger/violence and fear/anxiety
destruction = mellowing effect
What is Kluver-Bucy syndrome?
bilateral (both sides) destruction of amygdala
can result in hyperorality (put things in mouth a lot), hypersexuality, and disinhibited behaviour
What is the role of the hippocampus in the limbic system?
key role in forming new memories
converts short-term memories to long-term memories (if destroyed, still have old memories intact, just can’t make new ones)
What is the role of the hypothalamus in the limbic system?
regulates the autonomic nervous system (fight or flight vs. rest and digest)
controls endocrine system
