WMM Flashcards
Who made it
Baddeley and Hitch (1974`0
What is it
Model of how STM is organised and how its functioned
4 main components of working memory model
Central executiveEpisodic bufferPhonological loopVisuo spacial sketchpad
Central executive what it does
Focuses, divides and switches our limited attentionMonitors incoming data, makes decisions and allocates slave subsystems to tasks
Central executive capacity and storage
Limited processing capacityDoes not store information
Phonological loop what it does
Deals with sound
Phonological loop divided into
Articulatory process = allows rehearsal, capacity is 2 secsPhonological store = stores auditory information
Visuo-spatial sketchpad what it is and its capacity
VisualisingCapacity = 3/4objects
Visuo-spatial sketchpad subdivided into
Visual cache = stores visual dataInner scribe = records arrangement of things
Episodic buffer
Temporary acoustic, visual and spatial storeTime sequencingTransfers from/to LTMCapacity = 4 chunks
Strength
Baddeley found performance on visual and verbal together was same as separately. 2 visual or 2 verbal together = problemsshows slave subsystems
Weakness
CE may contain subcomponents So model is unfinishedcannot Find specific place in brain that lights up in scan for central executiveNo real evidence for it
Application
KF had poor STM auditory, processing was normalPhonological loop damagedNot global disorderAffects all memory functioning
