Multi Store Model Of Memory Flashcards
Sensory register
Capacity
High - e.g. over one hundred million cells in one eye, each storing data
Sensory register
Duration
Very brief - less than half a second
Sensory register
Coding
Depends on the sense - visual auditory etc
Sensory register
A stimulus from the environment passes into the sensory register along with lots of other sights and sounds - five different stores
Transfer from SR to STM
Little of what goes into the SR passes into the memory system - needs attention to be paid to it
Short term memory
Limited capacity and duration store
Short term memory
Duration
18-30 seconds unless info is rehearsed
Short term memory
Capacity
Between 5 and 9 items before forgetting occurs
Short term memory
Coding
Acoustic
Transfer from STM to LTM
We can keep info in the STM as long as we rehearse it, if we rehearse it long enough it passes into the LTM
Long-term memory
A permanent memory store - when we want to recall info it has to pass back through the STM in a process called retrieval
Long-term memory
Duration
Potentially up to a lifetime
Long-term memory
Capacity
Potentially unlimited
Long-term memory
Coding
Tend to be in terms of meaning e.g. Semantic
Whose theory was the multi store memory model?
Atkinson and shiffrin (1968)
