The multi- store model

Question 1

who developed the multi store model

Answer 1

Atkinson (1968)
Shiffrin (1971)

Question 2

what does the multi store model describe

Answer 2

• how information flows through the memory system
• suggest that memory is made up of three stores linked by processing

Question 3

what happens at the sensory receptor

Answer 3

• all stimuli form the environment passes into the sensory receptor
• has several receptors for the 5 senses
• has iconic and echoic coding
  duration is less than a second
  has a very high capacity
• information is transferred if you pay attention

Question 4

what happens in the short term memory

Answer 4

• coded acoustically
• last 18 seconds (so temporary store )
• limited capacity of 7+ or - 2
  maintenance rehearsal occurs when we rehearse material
• if rehearsal is long enough information passes to the long term memory

Question 5

what happens in the long term memory

Answer 5

• permanent memory store
• coded semantically
  duration of a lifetime
• information transferred back into the STM by retrieval

Question 6

strength of multi store model

Answer 6

1. reseach support
   - Baddeley (1966) found that we mix up words that sound similar when we are using our STM but mix up words that have similar meaning when using LTM

Question 7

limitation of multi store model

Answer 7

1. more than one STM store
   Shallice and Warrington (1970) studies client KF who had amnesia
   - KFs STM for digits was poor when they were read out to him but recall was much better when he read the digits himself
   - further studies showed there could be another STM store for non verbal sounds
   2.elaborate rehearsal
   - prolonged rehearsal is not needed for transfer to LTM
   - Criak and Watkins (1973) found that the type of rehearsal is more important than the amount
   - elaborate rehearsal is needed for long- term storage (linking inforamtion to exisating knowledge)
