Sc B-62 Section 3

Quiz:

My favorite image collection for parts: http://www.mhhe.com/socscience/intro/ibank/set1.htm

  • part; location; function
  • neocortex; outside of brain stem/limbic system; higher thinking, perception, motor, emotion etc...
  • frontal lobe; front part of neocortex between central fissure and lateral fissure; short term memory, social intelligence, decision making, impulse control, "workhorse" or higher thought (Richard), Brocha's area (grammatical functions), includes the motor cortex
  • brainstem; coming from spine into mid brain;
  • hippocampus; inside the temporal lobe; part of the limbic system (together with thalamus, hypothalamus and amigdila), Alzheimer's attacks this, responsible for encoding new memories (Alzheimer's supposedly cannot gain new memories but they can learn new motor skills if that part is not damaged, e.g. learn to play a new instrument (but then how do they remember what melody to play?!?!?!)), Parkinson's attacks basel ganglia hurting fine motor movements, London taxi drivers study showed that their right hippocampus was larger than normal, and the longer they have been driving the larger it was > spacial memory and direction
  • right hemisphere; right half of brain; creative side, because more white matter, intonation, music, rote memory, faces, creativity correlates with depression > more -ve than left hemisphere
  • pons; above thalamus, below mid brain (?); balance, heart rate, breathing, closely related to cerebellum
  • visual cortex; very back of head, on the occipial lobe; vision
  • sylvian fissure = lateral fissure
  • left hemisphere
  • cerebellum
  • synapse
  • hypothalamus
  • striatum
  • axon fibers
  • grey matter
  • white matter
  • temporal lobe
  • forebrain
  • central fissure
  • spinal cord
  • parietal
  • medulla oblongata
  • lobe-limbic microelectrodes
Apparition of Jesus: habituation/fatigue from firing
Border effect: lateral inhibition

SC B-62 Section 1

First section
Richard Griffin: griffin3@fas

  1. What is Freud's theory about why some people are excessively orderly and rule-bound? Is it testable? If so, how?
    • they were potty trained too early
    • according to Freud the time for each person is different - even for identical twins (fudge factor)
    • large sample size (all different influences would equal out to ze, pre-natal commitment, identical twins, train them at different times
    • not falsifiable
  2. Why would skinner object to the claim that students study hard because they want to get good grades? What would he say instead?
    • reinforcers (=reward)
    • bad word: want
    • re
  3. The image of the world on the retina is upside-down. Why don't people see the world upside-down?
    • consistent mapping
    • there is no need
    • goggle experiments - get habituated
  4. If a psychologist flashes a word in the left half of your visual field, could you read it? Why or why not?
    • yes
    • left visual field maps to the right side of the retina > right hemisphere of the brain
    • the corpus colossum will transfer the info to the left hemisphere
    • even if the cc is cut, one could read it, but not speak about it (read the word "pan" then he was able to draw it)
    • right hemisphere can recognize words - maybe not full sentences
  5. How do cognitive psychologists know that it takes about a half a second to retrieve the name of a printed letter?
    • discrimination of {a,A,b,B}
    • shape or meaning
    • response time was 400-600 ms
