multi store model Flashcards
(23 cards)
what is the multi store model
explanation of memory
who proposed the multi store model of memory
atkinson and shiffrin
what does the multi store model assume
assumes there are three separate memory stores and information is transferred between these stores in linear sequence
what is the sensory register
where sensory stimuli from environment is stored
what is another term the same as sensory register
sensory memory
what are the different senses within sensory register
iconic - images
echoic - sound
other sensory stores
how can environmental stimuli move through from sensory register to STM
by paying attention to that info
what capacity does sensory register have
large as it receives all sorts of info
how is info coded in sensory register
info coded depending on what sense it is coming from
what is the duration of info being in sensory register
very short - if attention is paid to info then it will go to STM
how is info coded in STM
acoustically
what is the capacity of STM
7 +/-2 items
what is duration of info being held in STM
18 -30 seconds
what can be used to keep information in STM
maintenance rehearsal (saying something over and over again)
how is info coded in LTM
semantically
what capacity does LTM have
unlimited
what is the duration of info being held in LTM
unlimited
how is info able to be recalled
information retrieval from LTM into STM
what case study supports the multi store model
Henry Molaison (HM)
what did doctors do to HM
they removed both hippocampus within his brain - surgery for epilepsy
what was HM unable to do after his surgery
he was unable to recall the operation, and could not remember speaking to someone an hour earlier
what type of memory was still intact for HM
short term memory
how does HM support the multi store model of memory
study of HM shows that LTM and STM are two distinct stores
