Baddeley and Hitch said that the STM is not a unitary store, that it is made up of the central executive and the three slave stores: the phonological loop, the episodic buffer, and the visuospatial sketch pad.
the central executive
very limited capacity
allocates tasks to the three slave stores
the phonological loop
processes auditory information
allows for maintenance rehearsal by being made up of the articulatory process
the visuospatial sketch pad
combines visual and spatial awareness information to give us a 'complete picture'
it is divided into the inner scribe and visual cache.
capacity of the vss is 4-5 chunks according to Baddeley.
the episodic buffer
integrates all type of information from other stores. including auditory, visual and spatial
crucial for linking stm to ltm.
