Flashcards in working memory model Deck (27):
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?
what are the systems in the wmm?
the central executive
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?
what is the ACS?
it is the inner voice
it is used to rehearse information from the PL
what is the inner ear?
what is the inner voice?
what is the inner eye?
what is the visuospatial sketchpad?
stores and manipulates visual information from the eye and ltm
what is the VSS split into?
the visual cache
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?
which case study supports?
brain damage to short term memory
found it difficult to process verbal info but his visual part of memory remained in tact
how is brain scans a support?
brain scans have shown that visual and acoustic encoding occur in different parts of the brain
