the msm of memory

• TRANSFER FROM SR TO STM- msm

  little of what goes into the SR passes further into the memory system- needs attention
• STM


  limited capacity

  duration= 18-30s unless info is rehearsed

  capacity= between 5-9 items before forgetting occurs

  coding= acoustic
• TRANSFER FROM STM TO LTM- msm

  - maintenance rehearsal occurs when we repeat material to ourselves

  - can keep info in STM as long as we rehearse it

  - if we rehearse it long enough it passes to the LTM
• LTM


  permanent memory store

  duration= potentially up to a lifetime

  capacity= potentially unlimited

  coding= semantic
• STRENGTHS OF MSM


  shows STM snd LTM are different
• TWO LIMITATIONS OF MSM


  - evidence suggests there's more than one type of STM

  - research supporting MSM are artificial and lacks external validity
