the multi store model

• what memory stores are included in the multi store model?

  sensory register, short term memory, long term memory
• what does the msm show?

  how information is travelled in one memory store to the next
• what can't be done during the msm?

  information can't bypass going through one of the stores
• the flow of information across the stores is called..

  unidirectional

  info travels in one direction
• what needs to be done for info to be passed from the SR to the STM?

  attention
• attention

  • If a person’s attention is focused on one of the sensory stores, then the data is transferred to the STM
  • The first step in remembering
• how does information travel from the STM to the LTM?

  repetition - maintenance rehearsal

  the more the info is rehearsed, the better it is remembered
• what is one prediction of the multi store model?

  each memory store can be damaged independently
• what happens if the LTM is damaged?

  info can still be stored in the sensory register and STM
• what happens if the STM is damaged?

  new long term memories can't be formed
• what is the sensory register?

  the place where info is held from each our senses and the corresponding parts of the brain
• what are the sub stores in the sensory register?

  the memory stores for each of our 5 senses, vision (iconic store - stored as images) and hearing (echoic store - stored as sound), touch (haptic store - stored as feelings)
• what code does the sensory register use?

  a sensory code
• the capacity of the sensory register..

  huge (millions of receptors)
• the duration of the sensory register..

  information lasts a very short time (around 1/2 a second - 2 seconds)

  • most information received remains for milliseconds
• what is the short term memory store?

  the store we use to store info for a short period of time while we need it to complete an ongoing / immediate task
• the duration of the STM store..

  limited: 18 to 30 seconds

  info will disappear or decay relatively quick if not rehearsed
• the capacity of the STM store..

  limited

  info will disappear from STM if new info enters - pushing out (displacing) the og info
• what code does the STM store use?


  a sensory code

  a semantic code

  • the main code: acoustic - information is stored in a sound based format
• what is the long term memory store?

  the store we use to retain information for long periods of time
• the duration of the LTM store..

  potentially unlimited
• the capacity of the LTM store..


  potentially unlimited
• what code does the LTM store use?


  most memories - a semantic code
• what is retrieval?

  the process of getting information from the LTM involves the information passing back through the STM

  • it is then available for use
• give one limitation of the msm

  isn't supported by findings from case studies
• who contributed to long term memory in the multi store model?

  endel tulving
• who developed the multi store model?

  attkinson and shiffin

  • describe how info flows through the memory system
  • model suggests that memory is made up of 3+ stores linked by processing
• cognitive psychology - how our minds deal with info it receives as well as our ability to use that info
