2. MSM

• Who proposed the Multistore Model of Memory?


  Atkinson and Shiffrin
• What is the MSM?


  • Representation of how memory works in terms of 3 stores: sensory register, STM, LTM
  • Describes how information is transferred from one store to another, how it is remembered and how it is forgotten
• What is the sensory register?


  • The memory stores for each of our 5 senses e.g. visual (iconic) and hearing (echoic)
  • Coding in iconic = visual
  • Coding in echoic = acoustic
  • Capacity of SR = huge, duration = lasts half a second
• What is the key process if you want information to pass further into the memory system?

  Attention
• How does STM information pass into the LTM store?

  Maintenance rehearsal: occurs when we repeat material to ourselves over and over again
• How do we recall information from LTM?


  • It has to be transferred back into STM through retrieval
  • No memories are recalled directly from LTM
• Evaluation of the Multistore Model of Memory

  • Supporting research evidence (Baddeley)
  • There is more than one type of STM (KF case study)
  • There is more than one type of LTM
  • There is more than one type of rehearsal (Craik and Watkins)
