The Multi-Store Model of Memory

• The Multi Store Model of Memory (MSM)

  Throughout these notes, I will refer to the Multi Store Model of Memory as MSM for simplicity.

  
  

  MSM by Atkinson and Shiffrin (1968) was the first cognitive explanation of memory. The model explains how information flows through a series of storage systems with 3 permanent structures in memory.

  
• From the MSM model we can see that there are three separate stores, sensory memory, Short-term memory (STM), Long-term memory (LTM).

  
• The Sensory memory takes in all the information from the senses. It has a very large capacity and very short duration. To transfer from the sensory memory to the STM we must pay attention. The STM has a small capacity and small duration, information is lost due to decay or displacement. There is a rehearsal loop to keep information in the STM. For information to go into the LTM, we must rehearse. One information is in the LTM it has the potential to stay a lifetime. Information is forgotten to interference of retrieval failure.
