multistore memory Flashcards
who was the theory devised by?
atkinson and shiffron
who was the theory devised by?
atkinson and shiffron
what did they propose?
that memory had three stores
what are the three stores in the mode?
sensory
short term
long term
what is the duration of the sensory memory?
0-1 seconds
what is the capacity of the sensors memory?
0
how does the sensory memory encode?
it is sense specific
how is information lost from the sensory memory?
if information is not paid attention to
what is the duration of the short term memory?1
1-20 seconds
what is the capacity of the short term memory?
7-/+ 2 items
how does the short term emery encode?
auditory
how is information lost from the short term memory?
through trace decay and displacement
lack of rehearsal
what is the duration of the long term memory?
months to years
unknown
what is the capacity of the long term memory?
unknown
unlimited
how does the long term memory encode?
mainly semantic but can be acoustic
how is information lost from the long term memory/
through trace decay, cue dependancy and repression
where is it key that rehearsal takes place?
in the short term memory in order to be transferred to the long
if information is not rehearsed in the STM what happens?
it is lost through displacement or decay
why is the model oversimplified? (W)
suggests that STM and LTM work together in a single unitary fashion which has now been found to not be true
wmm
why is rehearsal thought to be too simple? (W)
does not take into account other factors such as motivation to rehearse and learning strategies
who is the model supported by?
case studies such as clive wearing etc
shows that there are too separate stores
why is the model influential? (S)
it has allowed a good understanding of memory and the structure of different stores allowing it to be expanded and researched in order to improve the model
when ws it made?
1968
