Chapter 17 Flashcards
Describe the physiological theory of emotion cannon-bard
Emotional stimuli excite feeling of emotion in the brain and the expression of emotion in the autonomic and somatic nervous system.
Thus, feeling of emotion and autonomic and somatic nervous system responses to emotion are parallel processes
Describe the physiological theory of emotion James-Lange?
Feeling of emotion produced by autonomic activity and behaviors (rapid heart beat and running from threat result in scared feeling)
How did paper theory relate to current theories about neuroanatomical correlates of emotion?
Paper 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 paper proposed 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
- Septum
- Cingulate gyrus
- Fornix
- Hypothalamus
- Amygdala
- Mammillary body
- Hippocampus
What are the symptoms of kluver-bucy syndrome?
Behavior:
- consumption of almost anything that is edible
- increased sexual activity (often at inappropriate objects)
- a tendency to repeatedly investigate familiar objects
- a tendency to investigate objects with the mouth
- a lack of fear
List Elkman’s six primary facial expressions
- surprise
- anger
- sadness
- disgust
- happiness
- fear
Define facial feedback hypothesis
The hypothesis that are facial expressions influence our emotional experience
Define microexpression
A very brief facial expression that occurs involuntary when a person deliberately or unconsciously conceals a feeling.
What is the mirror-like system and how has it advanced our understanding of emotion?
The mirror-like system 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?
The level of circulating glucocorticoids.
Which brain structure is particularly susceptible to stress?
Hippocampus
