Psychology – The Working Memory Model: (Baddeley and Hitch)
Working memory model – a representation of short-term memory. The WMM refers to
the bit of information you are using, whilst working on a complex task, which requires
you to store information as you go along.
The Working Memory model: The model consists of four main components:
Central Executive
Episodic
Visuo-Spatial Phonological
Buffer
Sketch pad loop
Inner Scribe Phonological
and visual store
cache
Articulatory
Long-term Memory control
system
Central Executive:
The central executive has a, ‘supervisory role’.
It monitors incoming data.
Focuses and divides our limited attention.
Allocates subsystems to tasks.
CE has very limited capacity and does not store information.
Phonological Loop:
The Phonological Loop is the component of the Working Model that processes
information in terms of sound (acoustic). The phonological loop is divided into:
Phonological store – stores the words you hear.
Articulatory control system – allows maintenance rehearsal (repeating sounds in
a loop). The capacity of this loop, is believed to be 2 seconds worth of what you
can say.
Episodic Buffer:
The episodic buffer is a temporary store for information.
The EB combines visual, spatial and verbal information from other stores.
The EB maintains a sense of time sequencing (record events).
Storage component of the central executive.
