multi store model of memory

• 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 is the nature of the multi-store model?

  It is 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 to remember for each store?

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

  Modality specific
• What is the capacity of the sensory register?

  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
• What is the capacity of short-term memory?

  Seven items plus or minus two
• What is the duration of short-term memory?

  Between 18 and 30 seconds
• What are the two types of rehearsal for transferring information to long-term memory?

  Maintenance rehearsal and elaborative rehearsal
• What is the coding of long-term memory?

  Semantic coding
• What is the capacity of long-term memory?

  Potentially unlimited
• What does the research by Glanzer in 1966 demonstrate?

  The primacy and recency effect
• What did Sperling's study reveal about sensory memory?

  It has a larger capacity than short-term memory
• What did Baddeley's study show about short-term memory coding?

  It is coded acoustically
• What did Jacobs' research indicate about short-term memory capacity?

  It is around seven items
• How can the capacity of short-term memory be increased?

  By chunking information
• What did Peterson and Peterson's study find about short-term memory duration?

  It lasts between 18 and 30 seconds
• What does the research by Wagner suggest about long-term memory?

  It has a very large capacity
• What did Barrack's study reveal about long-term memory duration?

  It can last many decades
• What are the criticisms of the multi-store model of memory?

  • Lacks ecological validity
  • Lacks mundane realism
  • Simplistic view of memory
  • Assumes unitary stores
• What is a potential problem with the research methods used in memory studies?

  They may lack ecological validity
• What does the evolutionary theory suggest about sensory register capacity?

  It supports the need for quick reactions
• What is a limitation of the multi-store model regarding memory types?

  It suggests memory stores are unitary
• What is a key assumption of the multi-store model that lacks face validity?

  Long-term memories of taste and smells
