Multi-Store Model of Memory

• What is the multi-store model of memory?

  Describes memory as consisting of three separate stores: sensory memory, short-term memory, and long-term memory.
• What is the missing label in the diagram?

  Encoding

  
• What is the missing label in the model?

  Attention

  
• What is the missing label in the model?

  Retrieval

  
• What is the missing information in the model?

  Long-term memory

  
• What is the missing information in this model?

  Sensory memory

  
• What is the missing label in this model?

  Maintenance rehearsal

  
• What is sensory memory?

  The store where all immediate information is briefly held unless paid attention to
• What is short-term memory?

  The memory store that has limited capacity and limited duration, and where information becomes conscious
• What is long-term memory?

  The memory store that has unlimited capacity and unlimited duration, and where information is permanently stored
• What are the three different processes in the multi-store memory of model?

  • Encoding
  • Capacity
  • Duration
• What is the duration of sensory memory?

  0 - 18 seconds
• What is the duration of short-term memory?

  25 - 30 seconds
• What is the duration of long-term memory?

  Unlimited
• What is the capacity of sensory memory?

  All sensory experiences (5 senses)
• What is the capacity of short-term memory?

  7 +/- 2 items
• What is the capacity of long-term memory?

  Unlimited
• How is sensory memory encoded?

  Sense specific (different stores for each sense)
• How is short-term memory encoded?

  Mainly based on sound or hearing
• How is long-term memory encoded?

  Mainly meaning but can be visual and hearing
• STM has limited duration and capacity. So, if time runs out then it will decay. If the STM runs out of space, then information is displaced
• What is displacement?

  Information is pushed out of storage by new information, and so becomes forgotten
• How does displacement happen?

  If the short term memory runs out of space, then information is displaced and becomes forgotten
• Where does displacement happen?

  In the short term memory store
• What is maintenance rehearsal?

  Process of repeating information so that it stays in storage , temporarily or permanently
• How do we keep info in the short-term memory store?

  Maintenance rehearsal
• How does information tranfer from the short-term memory to long-term memory?

  Rehearse the information for about 30 seconds
• What is retrieval?

  Process of getting information back from the long term memory to the short term memory in order to be output
• Retrieval is not always possible
