multi store model

• Multi store model describes memory to process info passively
• multi store model is made up of sensory register, stm and ltm
• multi store model was the first model of memory proposed by Atkinson and shiffrin
• multi store model believe capacity of stm is 18-30 seconds
• multi model believes info is codes acoustically in stm and semantically in ltm
• multi store model believes the capacity of sensory register to be unlimited
• info is transferred from sensory register to STM when we pay attention to our environment (the stimuli)
• info is transferred from STM to LTM through prolonged rehearsal - when it is retrieved it is transferred back to STM
• info can be kept in STM through maintenance rehearsal
• sensory register:

  duration = brief

  capacity = very large

  coding = modality specific
• stm:

  duration= 18-30 secs

  capacity = 7+-2

  coding= acoustic
• ltm:

  duration= lifetime

  capacity= unlimited

  coding = semantic
• patient kf provides opposing evidence for MSM - he had good recall of digits from STM when he read them but poor recall when they were read to him - suggests there may be multiple stm stores
• supporting evidence- baddely - tested word recall of 4 groups with different word lists - found that acoustically similar words were more likely to get mixed up when using STM and semantically similar words were more likely to get mixed up when using LTM - shows a clear distinction / separation between the 2 stores, like the multi store model proposed
