    • What are the 3 stores of MSM?

      Sensory store, short-term memory, long-term memory
    • First step of MSM

      Input from environment is encoded
    • Duration and capacity of sensory store?
      Duration: 2 seconds
      Capacity: A lot, but limited by the duration
    • Duration and capacity of STM?

      Duration: 15-30 seconds
      Capacity: 5+-2 items
    • Duration and capacity of LTM?

      Unlimited!!
    • What can happen during sensory store?

      Decay: when info fades away over time
    • What has to happen in order for info in sensory store to transfer to STM?

      Attention to info
    • What can happen in the STM?

      Decay: when info fades away over time
      Displacement: info is pushed out by new info
    • What is maintenance rehearsal?

      Going over info in the STM to transfer to LTM.
      Decreases chances of decay
    • What has to happen in order for info in STM to transfer to LTM?

      Elaborative rehearsal: giving meaning to information in order to transfer to LTM.
    • What can happen in the LTM?

      Decay: info fades away over time
      Retrieval failure: when info cannot be recalled from the LTM
    • How is the MSM theory reductionist?

      Memory is incredibly complex, and reducing it down to 3 distinct stores oversimplifies this.
    • Why isn't the MSM theory supported by neuropsychological evidence?

      Recent studies have found that LTM has more than one store, so this contradicts the MSM.
    • 3 criticisms of the MSM theory?

      1. Reductionist - memory is incredibly complex, and reducing it down to 3 distinct stores oversimplifies this.
      2. Overemphasises the importance of maintenance rehearsal - There is evidence that attaching meaning to something is just as or more effective in recalling info
      3. Not supported by neuropsychological evidence - Recent studies show that LTM has more than 1 store, which contradicts the model
    • How does MSM overemphasise the importance of maintenance rehearsal?

      There is significant evidence that attaching meaning to info is just as or more effective in recalling info
    • 5 senses of sensory store (3 types of memories)

      Iconic memory: visual information (eyes)
      Haptic memory: things you touch
      Echoic: things you hear
