Emotion and Violence-Martin and Sweeny Flashcards
What are the 3 types of emotion?
- Basic=drives==> hunger, thirst. NOT represented in facial mm.
- Specific: in response to a particular stimulus
- General: emotion that lasts over a long period of time, separated from the context (without an immediate stimulus)
What 2 things determine drives?
homeostatic circuits and motivational circuits.
involves connections between the hypothalamus, ventral segmental region and the nucleus accumbens
What can perinatal anoxia disrupt? What can this lead to?
disruption of the reward circuits
can lead to hyperactivity and is associated with abnormal DA release, esp in the right hemisphere (need stronger stimulus to sense reward)
Which emotion is difficult to identify and why?
shame
it is involved in social interactions–> newly evolved emotion that is not present in other species
What are the types of shame? What are some functions of shame?
- humiliation
- embarrassment
- guilt
- shyness
shame is the “master of emotions”
- allows social structure to operate efficiently
- involved in rules
- self-esteem is the mirrored side of shame
How is guilt different from shame?
guilt is more specific to a situation and is less intensely negative
shame is the emotion of global failure –> often respond with anger
What is the difference between hubris and pride?
hubris=think you are globally the greatest thing
pride=more specific (like guilt for failure)
At what age to we begin to develop shame? What is necessary to develop shame?
2-3 years old
need to have a sense or right vs wrong to feel shame
If the prefrontal cortex is damaged, what will happen to a persons emotions?
disinhibition of emotional cortex—> no shame
What is Kluever-Bucy Syndrome?
behavior changes following bilateral medial temporal lobectomy including the amygdala. These monkeys were placid and fearless
What did patient SM with Urbach-Wiethe Disease teach us about the amygdala?
Amygdala invests sensory experience with emotional significance
- the pt could not draw faces w/ fear after loss of the anterior temporal lobes (including the amygdala but not the hippocampus)
- SM could still distinguish other emotions
What do people with right hemisphere damage experience? What does this imply about emotion?
- impaired speech and comprehension of emotional aspects of speech.
- can’t perceive humor
- deficits in “theory of mind”–> measures attribution of other person’s state f mind.
implies that emotion is lateralized to the right hemisphere
What do scans of pts with unipolar depression show (in comparison to non-depressed persons)?
increased activity and blood flow in the prefrontal cortex, amygdala, and mediodorsal nucleus of the thalamus.
dysregulation of emotion
What do PET scans in schizophrenic pts show?
asymmetry in cell loss (more pronounced on the right side)
Who developed the lobotomy?
