Multi Store Model

    Cards (9)

    • Who came up with the MSM?
      Atkinson and Shiffrin
    • What does the MSM consist of?
      • stores and processes
      • memory consists of separate stores
      • info transferred from STM to LTM via rehearsal
      • each store has diff capacity, coding and duration
      • STM and LTM are unitary and cannot be sub-divided
    • MSM diagram
      1. Stimulus from environment
      2. Sent to sensory register (no attention=decay)
      3. Attention= transfer to STM (no prolonged maintenance=decay/displacement)
      4. Prolonged maintenance rehearsal=transfer to LTM
      5. Maintenance rehearsal=allows for info to be stored in LTM
      6. Retrieval= LTM to STM
    • what is Decay
      memories fading away over time
    • what is Displacement
      when info in STM is replaced by new incoming info
    • AO3-MSM, supporting research
      P-research support for existence of separate STM & LTM store
      E-Baddley-research on diff coding in STM (acoustic) LTM (semantic)
      E-features of STM & LTM diff in characteristics
      L-supports idea of separate memory stores that are unitary & independent from each other
    • AO3-MSM, more than one type of rehearsal
      P-only accounts for 1 type of rehearsal
      E-Craik and Lockhart=strong memories created by processing NOT maintenance rehearsal. Info that is processed more deeply is more memorable
      E-suggested maintenance rehearsal and elaborative rehearsal needed for LTM storage and we need to be able to link info to existing knowledge and think about meaning.
      L- MSM does not consider diff processes in storing LTM.
    • AO3-MSM, brain scanning evidence

      P-neurobiological support for existence of STM & LTM
      E-Beardsley- prefrontal cortex active in STM. Squire- hippocampus active in LTM
      E-diff areas of the brain=diff memory tasks.
      L- MSM is an accurate model for memory.
    • AO3- more than one type of STM
      P- case study evidence= more than one type of STM
      E- Shallice & Warrington- Patient KF suffered brain damage after motorcycle crash. Digits presented to him visually was much better than verbal digit span test where he only recalled 2 digits.
      E- Contradicts MSM as model states that no matter how info is received it is still
      processed into STM AND LTM the same way.
      L- MSM oversimplified does not cover all aspects of STM
