The working memory model Flashcards
What was the Working memory model made to account for?
Dual-task studies
What are the parts of the WMM?
Central executive / Phonological loop / Visa-spacial sketchpad / episodic buffer (added later)
What is the Central executive?
The boss - Controls information which passes into the other slave systems, it is modality free
What is the Phonological loop?
Temporary storage for verbal information
What are the parts of the Phonological loop?
- Articulatory control system: Allows for maintenance rehearsal
- Phonological store: Temporary storage space for acoustic information
What is the Visuo-spacial sketchpad?
A temporary store for visual and spacial information
What are the two parts of the visuo=spacial sketch pad?
- The inner scribe: mental imaging which can hold 5 objects at once
- The visual cache: a store for visual and spacial information
What is the episodic buffer?
A store for all information before it passes to the Long term memory
What is the capacity of all the slave systems?
Limited
How does patient KF support the model?
He could access all his LTM but in terms of his short term could only remember visual information, not auditory suggesting they are two separate components
How do dual-task studies support the theory?
Visual and auditory tasks can be conducted at the same time but two visual or two auditory tasks can’t as they get overloaded suggesting that they are separate systems
