2.4 Working Memory Model
- Working memory model was
suggested by Baddeley and Hitch
(1974) to replace the idea of a
unitary STM store. Suggests a
system involving active processing
and storage.
- Central Executive
- Has a supervisory role, acting as a
filter. It determines which
information is attended to.
Allocates tasks for the other
systems.
- Has a limited capacity and only
deals with one piece of
information at a time.
- Has a supervisory role, acting as a
filter. It determines which
information is attended to.
Allocates tasks for the other
systems.
- Phonological Loop
- Deals with auditory information
and preserves the order in which
information arrives.
- Subdivided into two stores
- Phonological store
- Stores the words you hear
- Stores the words you hear
- Articulatory Process
- Allows for maintenance rehearsal
- Allows for maintenance rehearsal
- Phonological store
- Deals with auditory information
and preserves the order in which
information arrives.
- Visuo-Spatial Sketchpad
- Temporary memory system
responsible for holding visual and
spatial information
- Visual cache
- Stores visual data about form and colour
- Stores visual data about form and colour
- Inner scribe
- Records the arrangement of
objects in the visual field.
- Records the arrangement of

- Temporary memory system

- Episodic Buffer
- Acts as a backup store for information, integrating the visual,
spatial and verbal information and maintaining time sequencing.
- Links the working memory to long term
memory and wide cognitive processes.
- Acts as a backup store for information, integrating the visual,
spatial and verbal information and maintaining time sequencing.
- Evaluation
- Strengths:
- Dual task performance. Studies prove the separate existence of the visuo
spatial sketchpad. While carrying out a visual and verbal task at the same
time their performance was similar to if they carried it out separately
- Clinical evidence from KF study. KF suffered brain
damage from a motorcycle accident which damaged his
STM. His impairment was mainly for verbal information
while his visual store was largely unaffected.
- Dual task performance. Studies prove the separate existence of the visuo
spatial sketchpad. While carrying out a visual and verbal task at the same
time their performance was similar to if they carried it out separately
- Weaknesses:
- Little known of the nature of the Central Executive.
Needs to be more clearly specified than just being
'attention'. It is an unsatisfactory component which
challenges the integrity of WMM.
- Evidence to suggest the visuo-spatial scratchpad
is not unitary but divided into two.
- Little known of the nature of the Central Executive.
Needs to be more clearly specified than just being
'attention'. It is an unsatisfactory component which
