Memory: WMM Flashcards
central executive
main component, overall control, limited capacity
determines how brains ‘resources’ 3 slave systems, are allocated to tasks
phonological loop
deal w/ auditory info & preserves order of info
what is the phonological loop subdivided into?
Phonological store
Articulatory control system
phonological store
inner ear
stores words you hear
articulatory control system
inner voice
words silently repeated (looped)
visuospatial sketchpad
inner eye
stores visual and spatial info
organises info subconsciously
What is the visuospatial sketchpad subdivided into?
visual cache
inner scribe
visual cache
stores visual data e.g. form and colour
inner scribe
records arrangement of objects in a visual field
episodic buffer
a temporary store for info
info from each sub-system can inter-connect
A03 - separate memory stores
Patient KF
can’t process verbal info, can process visual
phonological loop damaged
supports separate visual and acoustic stores
A03 - dual task performance supports VSS
2 visual tasks simultaneously = worse performance (compete for same resources)
1 visual 1 sound = no interference. Sane performance lvl simultaneously as individual. evidence for VSS
A03 - central executive
Little research done to understand the central executive.
Capacity unknown
Richardson (1984) Problems specifying the precise function of the central executive.
Cannot be falsified.
