the multi store model of memory

Question 1

what is the multi model store of memory

Answer 1

Richard Atkinson and Richard Shiffin’s (1968 - 1971) multi - store model describes how info flows through through the memory system

The model suggests that memory is made up of three stores linked by processing

Question 2

how does the MSM ork

Answer 2

stimulus from the environment enters the sensory register

info then passes into the STM and after prolonged maintenance/ rehearsal it enters into the LTM

This can enter back into the STM by retrieval

Question 3

what is the sensory register

Answer 3

stimulus form the environment e.g. sound of someone’s name into the sensory registers along with lots of other sense like sights, smells and so on

this part of the memory is not just one but several for each of our five senses
the two main are:
- iconic ( visual info are coded here)
-echoic memory ( sound/ auditory info is coded here)

Question 4

how long does the material in sensory registers last

Answer 4

material in sensory registers last only very briefly - the duration is less than half a second

Question 5

what is the capacity of the sensory resistor

Answer 5

its can store a lot of material e.g. there is a million cells in an eye all storing data

Question 6

what is the capacity of the short term memory store

Answer 6

it is known to have a limited capacity because it can only contain a certain number of “things before forgetting takes place

STM is on average can hold between 5 and 9 items of info

Question 7

what is maintenance control

Answer 7

it occurs when we repeat (rehearse) material to ourselves over and over agin

we can keep info in the STM as long as we rehearse it

if we rehearse long enough, it passes into long term memory (LTM)

Question 8

what is the capacity of the long term memory store

Answer 8

it is a potentially permanent store of info if the info is rehearsed for a prolonged time

Psychologists believe that its capacity is unlimited and can last very many years

Question 9

how can we transfer material from the LTM to the STM

Answer 9

when we want to transfer material stored in LTM back to the STM, we use a process called retrieval ( remembering)

according to the MSM no memories are recalled directly from the LTM
