working memory model Flashcards
who came up with this model
Alan Baddeley and Graham Hitch 1974
what is it
explanation of how one aspect of memory (stm) is organised and how it functions
what is the WMM concerned with
parts of the mind that are active, when we are temporarily storing and manipulating info
what are the names of the four main components of WMM
- central executive
phonological loop
visuo-spacial sketchpad
episodic buffer
role of central executive
attentional process that monitors incoming data, makes decisions and allocates slave systems to tasks
-modality free (involved in everything)
capacity of central executive
very limited processing capacity
role of phonological loop
stores the words you hear
coding is acoustically
what is the phonological loop divided into
phonological store and articulatory process
role of articulatory process
allows maintenance rehearsal (repeating sounds or words in a loop)
capacity of this is 2 secs
role of visuo-spatial sketchpad
to hold static images and to manipulate them
eg, so if you are asked to work out how many windows are in your house and you visualise them
capacity of visuo-spatial sketchpad
three or four objects
what is the VSS divided into
visual cache - stores visual data
inner scribe - records arrangement of objects in visual field
role of episodic buffer
provides a temporary store for info received by central executive
capacity of episodic buffer
four chunks
