7 - the working memory model Flashcards
who came up with the working memory model
baddeley and hitch
what does the working memory model explain?
how stm is organised and how it functions when we are temporarily storing and manipulating information
what is the function of the central executive?
monitors incoming data, makes decisions and allocates slave systems to tasks
what is the capacity of the central executive?
very limited
what are the three slave systems in the working memory model?
phonological loop and the visuo-spatial sketch pad, and the episodic buffer
what type of information does the phonological loop deal with?
auditory information
how does the phonological loop code?
acoustically
what are the two sections of the phonological loop?
the phonological store and the articulatory process
what does the phonological store do?
stores the words you hear
what does the articulate process allow?
maintenance rehearsal
what is the capacity of the articulatory process?
2 seconds worth of what you can say
why do both slave systems in the working memory model access the ltm?
so we can learn the semantics of what we see and hear
what does the visuo-spatial sketch pad store?
visual and or spatial information when required
what did baddeley argue that the capacity of the visuo-spatial sketch pad is?
limited, around 3-4 objects
who believed that there was two parts to the vss?
logie
what did logie believe were the two parts to the vss?
the visual cache and the inner scribe
what does the visual cache store
visual data
what is the function of the inner scribe?
records the arrangement of objects in the visual field
who added the episodic buffer to the working memory model in 2000?
baddeley
what type of store is the episodic buffer
temporary store
what does the episodic buffer do?
intergratesbvisual, spatial and verbal information processed by the other stores, which maintains a sense of time sequencing which records events that happen
what is the capacity of the episodic buffer
around four chunks
