Working Memory Model Flashcards
(15 cards)
Who created the Working Memory Model?
Baddeley and Hitch
What is the Working Memory Model (WMM)
The WMM is a cognitive model of information processing to replace the STM store in the MSM. It’s an active processor made of multiple stores, unlike the unitary STM store.
Name the four main components of the WMM.
Central Executive, Phonological Loop, Episodic Buffer, Visual Spatial Sketchpad.
The PL is made up of: Primary acoustic store, Articulatory control process
The VSS is made up of: Inner scribe, visual cashe
What is the function of the Central Executive in the WMM?
The Central Executive is the head of the model; it receives sensory information, controls attention, filters information, and passes it on to the subsystems.
Subsystems:
Phonological Loop
Visual spatial Sketchpad
Episodic Buffer
What does the Phonological Loop process and what are its two subcomponents?
It processes sound information (acoustic coding) and contains the Primary Acoustic Store and the Articulatory Control Process.
What is the Primary Acoustic Store?
It is the “inner ear,” responsible for storing words recently heard.
What is the Articulatory Control Process?
It is the “inner voice,” responsible for storing information via subvocal repetition (silent, internal repetition without speaking out loud).
It has a capacity of about 2 seconds.
What does the Visual Spatial Sketchpad process and what are its two subcomponents?
It processes visual and spatial information (position, movement, and relationships between objects in space) and contains the Inner Scribe and Visual Cache.
Spatial describes how objects fit together in space
What are active stores in the WMM?
Active stores involve processing and updating information.
What are passive stores in the WMM?
Passive stores only temporarily hold information before it fades or is transferred elsewhere.
What is the Inner Scribe?
The Inner Scribe is the active store that holds the position, movement, and relationship between objects in 3D space.
What is the Visual Cache?
The Visual Cache is a passive store of form and color.
What is the Episodic Buffer?
The Episodic Buffer is a part of the WMM that temporarily stores and combines information from the phonological loop, visual-spatial sketchpad, LTM, and the central executive.
What is the role of Long-Term Memory (LTM) in the WMM?
LTM interacts with the WMM by providing information to and receiving information from the subsystems (phonological loop, visual spatial sketchpad, episodic buffer).
What is the difference between the MSM and the WMM?
The MSM has a unitary STM store, while the WMM proposes multiple, specialized stores for different types of information processing.
