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

  Sensory register, short-term memory, long-term memory
• What is the coding of the sensory register?

  Modality specific

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

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

  Short-term memory is coded acoustically
• What did Jacobs' research find about recalling numbers?

  People recall around nine numbers

  Recall was 90% after 15 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

  Inferences could be incorrect
• How does evolutionary theory support sensory register capacity?

  Quick reactions are vital for survival
• What is a criticism of the multi-store model regarding memory types?

  It oversimplifies memory processes
• What is a limitation of the multi-store model regarding long-term memory?

  It suggests long-term memory is unitary
