Multi-store memory model

• The coding sensory register is your 5 senses
• The capacity sensory register is very high
• The duration sensory register is less than 1/2 second
• Which 2 psychologists devised the multi-store model of memory?

  Richard Atkinson and Richard Shiffrin
• The sensory register contains 5 stores, name one that receives sound

  Echoic
• The sensory register contains 5 stores, name 1 that receives visual information


  Iconic
• What is the key process required for information to travel from the sensory register to the short-term memory store

  Attention
• Information can remain in the STM store for quite a long time if we keep repeating it to ourselves. What process is this?

  Maintenance
• What is the main type of coding used in the STM?

  Acoustic
• What is the main type of coding used in LTM store?

  Semantic
• Clive wearing suffered brain damage and he had amnesia, he greets his wife as if they were newlyweds 20 years on as Clive cannot remember her even if she left to make a cup of tea, he can still play the piano though
• Clive wearing's semantic memory was unaffected but his episodic memory was affected
• Clive Wearing supports different memory stores in LTM
• Strength- studies show STM and LTM are different

  Baddeley, mix up acoustically similar words in STM and words with similar meaning in LTM

  clearly independent stores useful model
• weakness- evidence of more than 1 STM store

  KF had amnesia, STM for digits is poor when read out loud but better when he read it himself

  MSM is wrong, more than one store, model is simplistic
• Weakness-prolonged rehearsal not needed in LTM

  Type not amount of rehearsal is important

  MSM doesn't explain how LTM storage is achieved
• The sensory register is the first store in the MSM that information passes through
