Multi-store model of memory:
Described by Richard Atkinson and Richard Schiffrin in 1968
It is an explanation of how memory processes work
The model involves 3 stores: short and long term and sensory
Maintenance rehearsal-
the more you rehearse
something the longer it will
Elaborative rehearsal-
rehearsing not only the
word but also it's meaning
Sensory store- evidence to indicate the duration of the sensory store
was collected by Sperling in1960, participants shown a grid of digits and
letters they were shown them for a blink of an eye then they were
either asked to recall them all or they had to recall a row after a tone.
When asked to recall them all they had poor recall 5 items recalled
about 42% whereas when only asked to recall one row recall was better,
3 items recalled was about 75%. This shows duration in sensory memory
is not very long unless rehearsed as decay happens very quickly.
The serial position effect- Glanzer and Cunitz in 1966, a list of words
are read out to people, they are then asked to recall any words they
remember, the results show the participants tend to remember the
words at the start (primacy) and the words at the end (recency) and the
words in the middle are forgotten. Primacy are most rehearsed so pass
into LTM, and recency are in short term memory as they are the last
words they hear.
Role of hippocampus- active when long term memory is engaged can
be tested using PET or fMRI scans. Shown by case study by Scoville and
Milner in 1957, HM had his hippocampus removed to reduce effects of
his severe epilepsy, after the operation HM could not form new
long-term memories but could remember things that happened before
his operation.
