2.1 The Multi-Store Model of Memory

• What are the three distinct stores proposed by the Multi-Store Model of Memory?

  Sensory register, STM, LTM
• The sensory register briefly holds sensory information from the environment
• The sensory register has a large capacity and a duration of milliseconds.
• What is the capacity of the short-term memory (STM)?

  7 ± 2 items
• The duration of information in the short-term memory (STM) is up to 30 seconds.
• The coding in the short-term memory (STM) is acoustic, based on sound.
• What is the capacity of the long-term memory (LTM)?

  Unlimited
• The long-term memory (LTM) uses semantic coding, which is based on meaning.
• Retrieval is the process used to bring information from LTM back to STM.
• Outline the process of information flow between the memory stores in the Multi-Store Model.

  1️⃣ Sensory information enters the sensory register

  2️⃣ Attention is required to transfer information to STM

  3️⃣ Rehearsal prolongs information in STM

  4️⃣ Information can be retrieved from LTM to STM
• What is the role of maintenance rehearsal in the Multi-Store Model?

  Transfer from STM to LTM
• What is the capacity of the sensory register?

  Large
• The duration of information in the sensory register is very short, lasting only a few milliseconds.
• Coding in the sensory register is based on sensory modalities like visual and auditory input.
• What is the capacity of the short-term memory (STM)?

  7 ± 2 items
• The duration of information in the short-term memory (STM) is up to 30 seconds.
• Rehearsal is required to prolong the duration of information in the short-term memory (STM).
• What is the capacity of the sensory register in the Multi-Store Model?

  Large
• The coding in the sensory register is based on sensory modalities.
• The short-term memory (STM) has a limited capacity and acoustic coding.
• What is the duration of information in the long-term memory (LTM)?

  Lifelong
• The coding in the long-term memory (LTM) is semantic, which is based on meaning.
• What is the capacity of long-term memory (LTM)?

  Unlimited
• The duration of information stored in LTM is lifelong
• LTM uses semantic coding, which is based on meaning.
• Steps involved in the retrieval process of LTM information

  1️⃣ Information is stored in LTM

  2️⃣ Retrieval is initiated

  3️⃣ Information is brought back to STM
• What type of coding is used in LTM?

  Semantic
• The process of bringing information back from LTM to STM is called retrieval
• Which feature distinguishes LTM from STM in terms of duration?

  Lifelong
• LTM uses acoustic coding, while STM uses semantic coding.

  False
• STM has a limited capacity of 7 ± 2 items.
• What is the capacity of STM?

  7 ± 2 items
• The duration of STM is up to 30 seconds.
• STM uses acoustic coding, while LTM uses semantic coding.
• What type of coding is used in STM?

  Acoustic
• The duration of LTM is up to 30 seconds.

  False
• What is the capacity of long-term memory (LTM)?

  Unlimited
• The duration of long-term memory (LTM) is lifelong.
• The coding in long-term memory (LTM) is primarily semantic
• What process is used to bring information from LTM to STM?

  Retrieval
