Chapter 17 Study Guide Flashcards
Describe Cannon-Brand physiological theory of emotion
Emotional stimuli excite feeling of emotion in the brain and expressions of emotion in autonomic and somatic nervous system. Thus, feeling of emotion and autonomic and somatic nervous system responses to emotion are parallel processes
How did Papez’s theory relate to current theories about neuroanatomical correlates of emotion?
Papez proposed that emotional expression is controlled by structures such as the amygdala, mammillary body, hippocampus, fornix, cingulate cortex, septum, olfactory bulbs, and hypothalamus. These structures that Papez proposed are some of the same ones that make up the limbic system, which is now believed to be important for emotion
List the structures of the limbic system
- Cingulate gyrus
- Fornix
- Hippocampus
- Mammillary Body
- Amygdala
- Hypothalamus
- Septum
What are the symptoms of Kluver-Bucy syndrome
- Consumption of anything edible
- Increased sexual activity
- Sexual activity directed at inappropriate objects
- Repeatedly investigate familiar objects, especially with mouth
- Lack of fear
Define facial feedback hypothesis
Facial expressions influence our emotional experiences
Define microexpressions
Method of distinguishing between true and false emotional expressions by identifying brief facial expressions of real emotion that break through the false one
What is the mirror-like system and how has it advanced our understanding of emotion?
Refers to the finding that certain patterns of brain activity are observed via fMRI scans when one experiences emotion or watches somebody else experience the emotion. This system is thought to be responsible for empathy in humans
What is the most common means of physiologically measuring stress?
Level of circulating glucocorticoids
Which brain structure is particularly susceptible to stress?
Hippocampus
Describe James-Lange physiological theory of emotion
Feeling of emotion produced by autonomic activity and behavior (rapid heart beat and running from threat results in scared feeling)
List Ekmans six primary facial expressions
Anger Fear Sadness Disgust Happiness Surprise
