Multi Store Model

• What psychological approach is related to the memory unit?

  The cognitive approach
• What are the main components of the multi-store model of memory?

  • Sensory register
  • Short-term memory
  • Long-term memory
• Who created the multi-store model of memory?

  Atkinson and Shiffrin
• What type of model is the multi-store model?

  An information processor model
• How is information processed in the multi-store model?

  In a linear direction
• What are the three stores in the multi-store model?

  Sensory register, short-term memory, long-term memory
• What are the three features of each store in the multi-store model?

  Coding, capacity, and duration
• What is the coding of the sensory register?

  Modality specific

  Potentially unlimited
• What is the duration of the sensory register?

  Approximately 250 milliseconds
• How does information move from the sensory register to short-term memory?

  Through attention
• What is the coding of short-term memory?

  Acoustic

  It helps understand memory processes
• What should students do with the multi-store model and its features?

  • Describe the model
  • Explain information flow
  • Recall coding, capacity, and duration
