Multi-store Model

    Cards (16)

    • Who made the model?
      Atkinson & Shriffin (1968)
    • What are the three components of the model?
      1. Sensory Register
      2. STM store
      3. LTM store
    • 1. What is the sensory register?

      It's a memory store for each of our 5 senses. All stimuli from environment passes through our sensory register.
    • 1. What is the duration of the sensory register?

      duration is very brief, lasts less than half a second.
    • 1. What is the capacity of the sensory register?

      Capacity is very large as lots of sounds and smells are being taken it at once.
    • 2. What type of coding is STM?
      Coding is mainly acoustically
    • 2. What is the duration of STM?

      lasts only around 18 seconds if not rehearsed
    • 2. What is the capacity of STM?

      has a limited capacity store
    • What is maintenance rehearsal?

      It is when we repeat material to ourselves over & over again. If we rehearse it long enough it passes to our LTM.
    • 3. What type of coding is LTM?
      Coding is mostly semantically
    • 3. What is the duration of LTM?
      can last up to a lifetime
    • 3. What is the capacity of LTM?
      Thought to be unlimited
    • How do we retrieve information from our LTM?
      according to MSM to recall information it needs to be transferred back into stm through retrieval.
    • What is one strength of MSM?
      - support from studies showing STM & LTM are different.
      - Alan Baddeley found we mix up words that sound similar when using our STM but we mix up words w/ similar meaning when we use our LTM.
      - this clearly shows that STM & LTM are separate stores
    • What is a counter to a strength of MSM?
      - many studies use artificial stimuli
      - material has no meaning
      - we form memories related to useful things - names, facts, faces.
      - MSM thus may not b a valid model of how memory works in our day to day lives
    • What is one limitation of MSM?

      - evidence for more than one STM store
      - Shallice & Warrington studies a client called KF who had amnesia
      - his STM for digits was very poor when read out to him but his recall was much better when reading out digits himself
      - further studies of KF & others show there could b another STM store for non-verbal sounds
      - this suggests MSM is wrong in saying there is just one store for STM.
