Introduction to The Working Memory
Baddeley and Hitch (1974) argue that the
representation of Short-Term Memory (STM)
provided by the Multi-Store Model is far too simple.
Baddeley & Hitch developed an alternative model for
the Short Term Memory, which they went on to call
the Working Memory.…read more

The Working Memory
Model (Baddeley & Hitch 1974)
The Phonological Loop: This contains the articulatory control system
(inner voice) and the phonological store (inner ear). All auditory
information is believed to directly enter the phonological store,
however the information decay rate is 2 seconds. This stores input
comes for the Long Term Memory or the ears.
Central Executive: Drives the whole system (e.g. the boss of working
memory) and assigns data to the subsystems (VSS & APL). It also deals with
tasks such as mental arithmetic and problem solving.
Visuo-Spatial Sketch Pad (inner eye): This is believed to hold visual information.
The eyes are used to store and manipulate visual and spatial information
such as remembering colours or shapes.…read more

The Working Memory
Model (Baddeley & Hitch 1974)
Strengths Weaknesses
A more realistic way of The model is limited
explaining how memory works in
everyday life
It is capable of doing dual tasks Does not explain changes in our
at the same time ability to process information
The Working Model does not The working model has come
over emphasise the importance from laboratory experiments
of rehearsal rather than real life settings, so
It may be hard to apply to
society…read more
