MSMM

• MSMM-

  • Atkinson and Shiffrin- 1968-71
  • Sensory register: takes the input from each sense, its modality specifically coded (stores depend on the sense), with a high capacity, and has the duration of 0.5 seconds.
  • STM: acoustically coded (Baddeley), with a capacity of 7+/-2 (Jacob’s) and a duration of 18-30 seconds (Peterson and Peterson).
  • LTM: semantically coded (Baddeley), with a potentially unlimited capacity and also potentially having the duration of a lifetime (Bahrick).
• MSMM-

  CPS- Shows the separation between short and long TM (Baddeley), like that a mix up of similar sounding words from the STM, and words that have similar meaning are mixed up when using our LTM.

  CPW- MSM may not be valid due to the experiments using digits/words which are constant syllables with no meaning.
• MSMM-

  W- Lacks mundane realism.  

  W- Too simplistic as it only shows part of memory.

  W- Shallice and Warrington (1970) studied KF who had amnesia, STM digits were poor, recall was better aloud – suggesting there’s anther STM for sounds.

  W- Prolonged rehearsal isn’t needed to transfer into the LTM – Craik and Watkins (1973) found the type of rehearsal to be more important, like elaborate rehearsal when you link the new knowledge to some old knowledge.
