The Working Memory Model Flashcards
(17 cards)
What does the working memory model (WMM) explain?
How short-term memory is organized and functions
Developed by Baddeley and Hitch in 1974.
What is the central executive (CE) responsible for?
Supervising, monitoring incoming data, focusing attention, and allocating tasks
The CE has limited processing capacity and does not store information.
What type of information does the phonological loop (PL) deal with?
Auditory information
Coding is acoustic and preserves order of information.
What are the two components of the phonological loop?
- Phonological store
- Articulatory process
What is the function of the phonological store?
Stores the words you hear
What does the articulatory process allow?
Maintenance rehearsal of sounds or words
It helps keep information in working memory.
What is the estimated capacity of the phonological loop?
Two seconds’ worth of speech
What type of information does the visuo-spatial sketchpad (VSS) store?
Visual and/or spatial information
According to Baddeley, what is the capacity of the visuo-spatial sketchpad?
About three or four objects
What are the two subdivisions of the visuo-spatial sketchpad?
- Visual cache
- Inner scribe
What does the visual cache store?
Visual data
What is the role of the inner scribe?
Records the arrangement of objects in the visual field
What is the episodic buffer (EB)?
A temporary store for integrating visual, spatial, and verbal information
When was the episodic buffer added to the working memory model?
In 2000 by Baddeley
What is the capacity of the episodic buffer?
About four chunks
What does the episodic buffer link working memory to?
Long-term memory and wider cognitive processes
True or False: The central executive can store information.
False
