  An area focusing on mental processes
• Who created the multi-store model of memory?

  Atkinson and Shiffrin
• 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 memory 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?

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

  Through attention

  Very large, potentially unlimited
• What does the primacy-recency effect suggest about memory?

  Long-term and short-term memory are separate
• What did Sperling's study demonstrate about sensory memory?

  It has a larger capacity than short-term memory

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

  Average recall of seven letters

  Recall was 80% after 48 years
• What is a criticism of the multi-store model regarding ecological validity?

  Research lacks real-life application
• What is a limitation of the tasks used in memory research?

  They lack mundane realism

  Quick reactions are vital for survival
• What is a criticism of the multi-store model's view of memory stores?

  It oversimplifies memory processes
• What is a key assumption about short-term memory in the multi-store model?

  It is a unitary and passive store
