Multi Store Model of Memory Flashcards
What type of model is the MSM?
A structural model of memory.
What are the 3 stores of the MSM?
Sensory register, long term store and short term store.
STM and LTM are unitary stores
What are the processes involved in the MSM?
Describes the process in which info is transferred from one store to another.
Processes are attention and verbal rehearsal.
Suggests that info passes from store to store in a linear way.
How is info initially revieved in the MSM?
By the sensory register.
Senses constantly revieve info and sensory memory allows us to retain an impression of a stimulus recieved by senses.
When recieving a visual input, how long does the image remain with us for?
approximately 0.5 seconds in a relitavely unanalysed form.
After this any info that is not processed further is forgotten.
What does modality specific mean?
the storage occurs within the sensory system that recieved the info. (iconic and echoic memeory store)
Where does some of the info in the sensory store get passed on to?
The short term memory if the info is attended to - only some of the info is passed on to the stm sucessfully through attention which allows us to store the info long enough to be able to use it.
How limited is the storage of STM?
has a limited capacity of 7 +/-2 and a duration of 18 seconds.
What happens if the info in the sensory register is not attended to?
it will be forgotten
Why is info held in the STM vulnerable?
It is vulnerable to disruption from internal/ external distractions which can lead to displacement.
Where does the info in STM move to next?
LTM
What is the capacity of the LTM store?
Unlimited
How does the info from the STM move to the LTM?
Through rehearsal which is generally acoustic
What happens if info is not rehearsed?
It will decay
What did Attkinson and Schiffner find?
The more the info is rehearsed the more likely it is to be retained.
