the multi store model

• who created the multi-store model?

  Atkinson & Shiffrin
• what year/s was the multi store model created?

  1968/71
• what is the first part of the multi store model?

  stimulus from environment
• what occurs after stimulus from environment?

  sensory register - iconic, echoic, other sensory stores
• what occurs after the sensory register?

  short-term memory store
• what comes off of the short term memory store (going down)

  response (remembering)
• what process comes in between short-term memory store & long-term memory store?

  prolonged rehearsal
• what process occurs going from long-term memory store back to short-term memory store?

  retrieval
• what process occurs from prolonged rehearsal to short-term memory store?

  maintenance rehearsal (rehearsal loop)
• what is the sensory register?

  includes input from all our senses & has sensory store for each
• what are the 2 main stores in the sensory register?

  -iconic memory

  -echoic memory
• what is iconic memory?

  visual-coded
• what is echoic memory?

  sound-coded acoustically
• what is the duration of the sensory register?

  less than 1/2 a second
• what is the capacity of the sensory register?

  extremely high
• what is the capacity of short term memory?

  7+ or -2 items
• what is the duration of short term memory?

  up to 30 seconds
• what is short term memories' coding?

  acoustic
• what is maintenance rehearsal?

  repeating material to keep it in STM
• what is the long term memory's capacity?

  unlimited
• what is the duration of long term memory?

  unlimited
• what study supports LTM duration being unlimited?

  Bahrick et al 1975
• what was Barick et al's study?

  found people can remember names & faces of classmates from 50 years previously
• what is long term memory's coding?

  semantic
• what are the strengths of the multi store model?

  -evidence supports that there are 2 separate stores

  -primacy & recency effects - STM and LTM stores are different
• what study is supporting evidence that there are 2 separate stores?

  Baddeley - LTM stored semantically & STM stored acoustically
• what study supports primacy & recency effects being shown

  -Bahrick's facial & name recognition

  -Peterson & Peterson's 15-30 sec duration for STM
• what case studies support separate stores?

  -HM

  -Clive Wearing
• what are the limitations of the multi store model?

  -not everything we remember is rehearsed

  -too simplistic

  -evidence based on artificial material

  -more than one type of LTM
• explain how its too simplistic

  some suggest there's more than 1 type of STM store

  e.g. people with amnesia such as patient KF
• explain evidence based on artificial material

  we mainly form memories based on important things, or things we are interested in, but studies use random words, syllables & numbers with no meaning
• what study supports there is more than one type of LTM

  Tulvig - how to ride a bike is stored differently to WW2 facts
