multistore model

• Who proposed the multi-store model of memory?

  Atkinson and Shriffin
• What does the multi-store model of memory demonstrate?

  How information flows through the memory system
• According to Atkinson and Shriffin, how many stores compose the memory system?

  Three
• What links the three stores in the multi-store model?

  Processing
• What is the first store in the multi-store model?

  Sensory register
• Where does information entering the sensory register come from?

  The environment
• How many senses have a store in the sensory register?

  Five
• What are the two main parts of the sensory register?

  Echonic and Iconic
• What type of information is stored in the echonic store?

  Acoustic information
• What type of information is stored in the iconic store?

  Visual information
• What is the duration of information in the sensory register?

  Less than half a second
• Why must information be passed to another store from the sensory register?

  To prevent it from being forgotten
• What is the capacity of the sensory register?

  Large
• Approximately how many cells do each of our five senses have in the sensory register?

  Over one million
• What causes information in the sensory register to enter deeper into the memory store?

  Paying attention
• What is the second store in the multi-store model?

  Short term memory
• What is the capacity of short term memory?

  7±2 items
• How is information coded in short term memory?

  Acoustically
• What is the duration of information in short term memory?

  Between 18 and 30 seconds
• What allows information to pass from short term memory to long term memory?

  Rehearsal
• What is the third store in the multi-store model?

  Long term memory
• What is the capacity of long term memory?

  Unlimited
• How is information coded in long term memory?

  Semantically
• What must happen to information in long term memory to recall it?

  It must be passed back to short term memory
• Who conducted a case study into KF?

  Shallice and Warrington
• What condition had KF been diagnosed with?

  Amnesia
• When was KF's recall for digits poor?

  When digits were read out to him
• When did KF's recall for digits improve?

  When he read digits to himself
• How does KF's case study challenge the multi-store model?

  It suggests STM is more than one store
• What does KF's case study imply about the composition of STM?

  STM is composed of more than one store
• Why is population validity limited in Shallice and Warrington's study?

  They only studied one patient
• Why is generalisability limited in Shallice and Warrington's study?

  They only completed a case study
• What was HM known as?

  'The man with no memory'
• How does the case study of HM support the multi-store model?

  He could do STM but not LTM
• What does HM's case study suggest about the relationship between STM and LTM?

  They are two independent unitary stores
• Where are STM and LTM located, according to the HM case study?

  Separate parts of the brain
• What is a counter argument to the idea of LTM as one unitary store?

  LTM could be composed of two or more stores
• What ability did KF retain despite struggling to form memories?

  To perform motor skills
• Who researched coding in memory?

  Baddeley
• What did Baddeley's research support about long term memory?

  It is coded semantically
