    (non-declarative) memory can be doubly
    dissociated

  • functional imaging data from normal subjects
    confirms lesion studies
  • be skeptical!

14
Long-term Memory
  • What would it be like to possess the ability to
    remember everything?

15
Long-term Memory
  • Case study of S. (Solomon Shereshevskii)
  • Russian journalist
  • never took any notes, recalled everything
    verbatim
  • thought this was normal

16
Long-term Memory
  • Alexander Luria - Soviet neuropsychologist

17
Long-term Memory
  • Shereshevskii suffered from synaesthesia
  • stimulation of one sense leads to automatic
    stimulation of another
  • hearing a sound produces a visual experience
  • I can see the music

18
Long-term Memory
  • random number table

Long-term Memory
1 this is a proud, well-built man 2 is a
high-spirited woman 3 is a gloomy person 6 is a
man with a swollen foot 7 is a man with a
moustache 8 is a very stout woman - a sack
within a sack. As for the number 87, what I
see is a fat woman and a man twirling his
moustache

  • What do you think the brain of someone that has
    this super memory would look like?

24
Long-term Memory
  • What if I told you it looked like this?

  • macroencephaly

Long-term Memory
  • 98 retention rate for reading material
  • reads on average 8 books a day (has
    approximately 9000 memorized!)
  • one page every 8-10 seconds
  • also has incredible memory for music, often
    remembering compositions only experienced once

Long-term Memory
What could support this ability?
Does brain damage stimulate compensatory developm
ent in some other area of the brain, or does
it simply allow otherwise latent abilities to
emerge?
