msm Flashcards
multistore model
- created by Atkinson and shiffrin 1968
- its a linear model - info moved through one direction
- passive stores - stores hold onto info before being passed/lost
3 msm stores-
- sensory register
- short term memory
- long term memory
features of each store
- coding - format information is stored in
capacity - how much information can those stores hold
duration - how long can they be held in that store before its lost
sensory information
sensory register
= store that directly receives sensory information
coding - sensory information
store depends on sense organ that info coms from , which is modality specific
capacity- sensory information
- very large, only what is paid attention to is passed to stm
duration - sensory information
- very short, as low as 250 milliseconds , as so much information is held , it can’t be retained for very long
each store has diff duration
coding - stm
- info is stored acoustically ( in form of sound / spoken words)
where does the sensory register move information to
stm through attention
any info that isn’t paid attention to is lost
capacity - stm
- 7 items + or - 2
duration - stm
18 - 30 secs, short time
info that isn’t retained = lost
info that isn’t lost can be passed through final store through rehearsal
coding - ltm
- stored semantically , in the form of meaning
capacity - ltm
- very large, haven’t found a limit yet
- info can be lost but not bc its out of the room , it may still be in the ltm but just not accessible
duration- ltm
- potentially unlimited, can still recall childhood events
OVERVIEW AO1
sensory information -
coding - modality specific
capacity- unlimited
duration - 250ms
stm -
coding - acoustic
capacity - 7 +/-2 items
duration - 18-30 secs
ltm -
coding - semantic
capacity- unlimited
duration - forever
support, evidence
p =. evidence shows that stm and ltm are differnet
e- baddeley found that we mix up words that found similar when using our stm, but we mix up words that have similar meanings when we’re using our ltm
e- shows the coding is different , supporting key feature of the model
l-
limitation , outdated
p- outdated and oversimplified , doesn’t fully explain complexity of memory
e - amnesiac patients = support idea that stm and ltm are seperate stores
e- but, evidence shows that stm and ltm not unitary stores = ltm consists of episodic ( personal experiences), semantic (facts) and prodecual ( skills), which msm doesn’t account for
l- but although its oversimplified , its a good starting point, which inspired further research
limitation, artifical tasks
p- msm research involves using artificial tasks , e.g recalling random letters, doesn’t reflect how we use memory irl
e- e.g Peterson and Peterson had ppts memorise nonsense trigrams
e- but irl ,we memorise faces names events, makes la studies lack mundane realise
l- research doesn’t accurately explain how memory works
