Multi-store model of memory Flashcards
Who devised this model?
Atkinson and shiffrin
How many types of information stores does it argue that there is?
3
What are the 3 types of info stores that it argue?
- sensory memory
- Short term memory
- Long term memory
What is the capacity of the sensory memory?
relatively large
What is the duration of the sensory memory?
Seconds
What is the encoding type of the sensory memory?
Modality specific (Covers everything)
What is the capacity of the STM?
7 +- 2 items
What is the capacity of the LTM?
Unlimited
What is the Duration of the LTM?
Minutes to a lifetime
What is the duration of the STM?
Around 30 seconds
What is the encoding type of the STM?
Acoustically encoded
What is the encoding type of the LTM?
Semantically encoded
What happens to the information in the sensory memory if it is not paid attention to?
It decays
How does information get from the sensory memory to the STM?
By being paid attention too
What happens to the info in the STM if it is not rehearsed?
It gets displaced or decayed
How does info get from the STM to the LTM?
It needs to be rehearsed
What happens to info in the LTM to stop it being Retrieved?
- There is interference
- it has decayed
- There is retrieval failure
How does info get back to the STM from the LTM?
By retrieval
