Multi Store Model Flashcards
What is the capacity for the sensory register?
Very large storage of information from each of the senses
What is the duration for the sensory register?
Extremely brief - less than half a second
What is the coding for the sensory register?
Codes according to the sensory source
eg. I for from the eyes is coded visually - iconic memory - and sound based information is coded acoustically - echoing memory.
What is the capacity for the STM?
Very limited capacity - about 7 chunks of information
What is the duration for the STM?
Very short - about 18 seconds
What is the coding for the STM?
Thought to be mainly acoustic
What is the capacity for the LTM?
Potentially unlimited capacity
What is the duration for LTM?
Potentially lasts almost a whole lifetime
What is the coding for the LTM?
Thought to be mainly semantic
Give a STRENGTH for the MSMM:
1) Studies show that STM and LTM are different.
Eg. Baddeley found that we tend to mix up words that sound similar when using STM, but we mix up words that have similar meanings when using LTM.
2) KF suffered brain damage from a motor cycle accident. STM reduced to 2 digits but could still form new LTM memories. Supports a distinction between STM and LTM, consistent with MSMM.
3) Clive Wearing suffered brain damage as a result of a virus. He is unable to lay down new LTM but can hold a brief conversation and has some STM. Supports the model as it suggests separate STM and LTM stores.
Give a WEAKNESS of the MSMM:
1) Clive Wearing suffered brain damage from a virus. Clive Wearing had some LTM intact (eg. Piano) but couldn’t recognise photos of his college. Suggests a distinction in LTM between procedural and declarative memories. Not explained in MSMM.
2) KF could form new LTM without a normal STM, challenging the MSMM.
