Lesson 5: The Working Memory Model Flashcards
Who created the Working memory model (WMM)
Baddely and Hitch (1974)
Why was the working memory model created?
They QUESTIONED the idea proposed by the multi store model of memory that -> people only have ONE STM store.
-also argued that STM=more complex than simply being a TEMPORARY store for information before being passed onto the LTM
What is the working memory model?
It is a COGNITIVE model of short term memory comprised of FOUR main components:
1) Central executive
2) Visuo-Spatial sketchpad
3) Phonological loop
4) Episodic buffer
What is the Central executive?
it DRIVES the whole working memory system and ALLOCATES data to the other components-> known as slave systems
What cognitive tasks does the central executive deal with?
-Decision making
-Reasoning
-Problem soving
How can automated tasks help the central executive?
Individuals have a limited ATTENTIONAL DEMANDS,
tasks that are AUTOMATED make
less ATTENTIONAL DEMANDS on the central executive leaving us free to perform other tasks.
What is the Phonological loop?
The component of working memory that deals with SPOKEN and WRITTEN material.
What are the two sub-components of the Phonological loop?
Phonological Store
Articulatory Loop
What does the Phonological store do?
(HINT: perception)
It is linked to speech PERCEPTION + holds information in speech-based form (i.e. spoken words) for 1-2 seconds.
What does the Articulatory loop do?
(HINT: production)
It is linked to speech PRODUCTION and is used to REHEARSE and STORE verbal information from the phonological store.
This allows for maintenance rehearsal.
What is the Visuo-spatial sketchpad?
component of WMM that stores and processes information in a VISUAL or SPATIAL form.
used for navigation
What are the two sub components of the visuo-spatial sketchpad?
Visual Cache
Inner Scribe
What does the visual cache do?
Stores visual material about FORM and COLOUR
What does the Inner scribe do?
Handles spatial relationships
What is the name of the fourth store Baddely added in 2000
The episodic buffer
