working memory model Flashcards
(27 cards)
who was the model devised by?
baddeley and hitch
what part of the memory does the model look at?
short term memory
why was the model created?
believed that short term memory was not one unitary store
it is an active process that manipuplates information
how many systems are there in the wmm?
three
what are the systems in the wmm?
the central executive
phonological loop
visuospatial sketchpad
what is the central executive?
very key component in the model
it acts as a boss
it has the capacity to focus divide and switch attention
allocates information to specific slave systems
chooses what to focus on
what kinds of tasks can the CE deal with?
cognitive tasks such as problem solving
what is the phonological loop split into to?
the phonological store
articulatory control syste
what is the PL?
it deals with spoken and written information
what is the PS?
acts as the inner ear
holds information about speech based information
how long can speech based info be held in the PS?
1-2 seconds
what is the ACS?
it is the inner voice
it is used to rehearse information from the PL
what is the inner ear?
the PS
what is the inner voice?
ACS
what is the inner eye?
visuosplatial sketchpad
what is the visuospatial sketchpad?
stores and manipulates visual information from the eye and ltm
what is the VSS split into?
the visual cache
inner scribe
what does the visual cache do?
deal with information about form and colour
what doe the inner scribe do?
deals with spatial information and rehearses information
what does the wmm suggest about doing tasks?
that it is easier to do 1 visual and 1 verbal task
what are the two predictions from the model?
that id two tasks use the same component it is impossible for them to successfully work together
2 diff takss is good
what was added 26 years later/
the eposodic buffer
what is the episodic buffer?
binds all information from each system togeterh and linked time and order
when was it made?
1974
