The multi-store model of memory Flashcards
Who came up with the multi-store model?
Richard Atkinson and Richard Shiffrin;

What is the role of the sensory register
Where all stimuli from the environment passes into.
It compromised several registers (stores) for each of our five senses:
e.g vision (iconic store) and hearing (echoic store);
What is the coding in the sensory register?
Iconic- visual
Echoic- acoustic;
What is the duration of the sensory register?
Less than 0.5 secs;
What is the capacity of the sensory register?
Very high- over 100 million cells in one eye each storing data;
When will information pass further into the memory system from the sensory register
If you pay attention to the information;
How is information coded in the STM store?
acoustically- lasts 18 secs unless it is rehearsed;
What is the capacity of the STM
Limited- input prices can only contain a certain number of ‘things’ before forgetting
May be 7+/- 2 (more likely 5);
What is Maintenance rehearsal?
Verbally repeating an item to keep it in memory- if we rehears stuff enough it can pass from STM -> LTM;
How is information coded in the LTM?
semantically;
What is the duration of the LTM?
Potentially a lifetime;
How do we recall information from the LTM?
retrieval from LTM -> STM;
Strengths of the MSM
- support from other studies (e.g Baddeley) that show that STM and LTN are separate and independent stores- high concurrent validity;
Weaknesses of the MSM
- there is evidence that there are more than one STM and LTM store
- many studies supporting the msm have very low ecological validity (e.g Jacobs)
- does not fully explain how long-term memory storage is achieved;
