Multi store memory model

• What are the three separate stores in the multi-store memory model?

  Sensory register, short term memory, and long term memory
• How is information transferred from one memory store to another in the multi-store memory model?

  Through processes like attention and rehearsal
• What are the two main stores of the sensory register?

  • Iconic (visual)
  • Echoic (sound)
• What is the duration of the sensory register?

  Less than half a second
• What happens to most information in the sensory register?

  Very little goes into short term memory unless attention is paid
• What is the capacity and duration of short term memory?

  Capacity is 7 ± 2 items, duration is 18-30 seconds
• How is information coded in short term memory?

  Acoustically
• What technique can be used to maintain information in short term memory?

  Maintenance rehearsal by repeating the information
• What is the role of rehearsal in transferring information to long term memory?

  If rehearsed long enough, information transfers to long term memory
• What is the capacity and duration of long term memory?

  Unlimited capacity and duration
• How is information coded in long term memory?

  Semantically
• What is required to recall information from long term memory?

  It needs to be transferred back into short term memory
• Which part of the brain is active during tasks in short term memory?

  The prefrontal cortex
• Which part of the brain is active during tasks in long term memory?

  The hippocampus
• What does the case of HM demonstrate about memory stores?

  • Operation on the hippocampus
  • Could not form new long term memories
  • Proves that memory stores are separate
• What does the case of KF suggest about short term memory?

  • Patient had amnesia
  • Better recall when reading digits
  • Suggests STM is split into visual and acoustic parts
• What are the strengths and weaknesses of the multi-store memory model?

  Strengths:

  • Research evidence
  • Simple to understand

  
  

  Weaknesses:

  • Case of KF
  • Elaborative rehearsal needed for LTM
  • Doesn't explain flashbulb memories
  • Uses artificial materials
• Why is elaborative rehearsal important for long term memory?

  It helps maintain information in long term memory
• What is a limitation of the multi-store memory model regarding flashbulb memories?

  It doesn't explain how flashbulb memories go straight to long term memory
• What type of materials are often used in research for the multi-store memory model?

  Artificial materials
