The multi store model of memory

• What does the multi-store model (MSM) consist of?

  Three stores linked by processing
• What did Baddeley find regarding STM and LTM?

  They use different coding methods
• How does Baddeley's research support the MSM?

  It shows different coding in STM and LTM
• What is the limitation of the MSM regarding types of STM?

  It assumes there is only one type of STM
• What evidence challenges the unitary view of STM?

  Studies of patients with amnesia
• What did Shallice and Warrington discover about patient KF?

  His recall improved when reading digits himself
• What does the evidence from amnesia suggest about STM?

  There may be different stores for verbal and non-verbal information
• What is the sensory register in the MSM?

  Memory stores for each of our five senses
• How is information coded in the iconic sensory register?

  Visually
• How is information coded in the echoic sensory register?

  Acoustically
• What is the capacity of sensory registers?

  Huge, millions of receptors
• How long does information last in sensory registers?

  Less than half a second
• What happens to information in the sensory register if attention is not paid?

  Very little passes further into the system
• What are the key features of the multi-store model (MSM)?

  • Three stores: sensory register, STM, LTM
  • Information transfer between stores
  • Coding, capacity, and duration differences
• What are the strengths and weaknesses of the MSM?

  Strengths:

  • Supported by experimental evidence
  • Clear structure of memory processes

  
  

  Weaknesses:

  • Oversimplifies types of memory
  • Relies on artificial materials in studies
• What are the two main types of sensory memory?

  • Iconic memory (visual information)
  • Echoic memory (auditory information)
• What is the role of attention in memory processing?

  • Key process for transferring information
  • Determines what information moves to STM
• What is the difference between STM and LTM in terms of coding?

  • STM: Acoustic coding
  • LTM: Semantic coding
• How does the MSM explain the flow of information in memory?

  1. Stimulus enters sensory register
  2. Attention transfers to STM
  3. Rehearsal can transfer to LTM
• What is the significance of Baddeley's findings for the MSM?

  • Demonstrates distinct coding methods for STM and LTM
  • Supports the idea of separate memory stores
• What does the research on amnesia suggest about memory stores?

  • Indicates multiple types of STM and LTM
  • Challenges the unitary store concept of MSM
