WORKING MEMORY MODEL
Baddeley and Hitch (1974)
- Within Working Memory, one memory system handles sound (the Phonological
Loop or “inner ear”) and another handles vision (the Visuo Spatial Sketchpador
“inner eye”).
- These two “slave systems” are managed by the Central Executive.
- The CE itself doesn’t handle memories but it allocates them to the slave systems.
- It retrieves information from the 5 senses or from LTM and assigns it to the Loop or
the VSSP for processing. It has non-specific modality – it can process sight, sound or
any of the 5 senses.
- The Phonological Loop seems to be split into two subsystems: an Articulatory Loop
(inner voice) which voices information you are rehearsing.
- Primary Acoustic Store which just holds on to the memory of sounds. The
Articulatory Loop (or Process) engages in something called "subvocalizing" which is
that mental "talking to yourself" that goes on in your head. It's similar to the
Rehearsal Loop in the Multi Store Model.
- In 2000, Baddeley published a new version of Working Memory with a new, third
slave system: the Episodic Buffer.
- This system works between the Loop and the VSSP and specialises in episodic LTM,
bringing elements of information together into patterns or stories.
- The Episodic Buffer is a temporary storage system that is able to combine
information from the loop, the sketchpad, long-term memory, or from perceptual
input, into a coherent episode
- The Central Executive picks and chooses the information from the Phonological
Loop and the VSSP that go into the Episodic Buffer to form an episode of memory.
- The Episodic Buffer also seems to "download" episodes from LTM, sending them on
to the Central Executive to be analysed and maybe recalled to conscious memory
