Working Memory Model Flashcards
What memory store does this regard
Short term memory
Central Executive
Drives the whole system and allocates data to the subsystems
Deals with cognitive tasks such as mental arithmetic and problem solving
Visuo-Spatial Sketchpad (inner eye)
Stores and processed information in a visual or spatial form
Used for navigation
Phonological loop
Deals with spoken and written material
Can be used to remember phone number
Phonological Store (inner ear)
Linked to speech perception
Holds info in speech based form for 1-2 seconds
Articulatory control process (inner voice)
Linked to speech production
Used to rehearse and store verbal info from the phonological store
What are the two sub parts of the phonological loop
Phonological store
Articulatory control process
What type of explanation is the WMM
Holistic explanation of STM
When was the WMM updated
2000
What did they add in the 2000 update and why
Episodic buffer
Model failed to explain the results of various experiments
Episodic buffer
Backup store
Communicated with both long term memory and the components on working memory
What case study supports the WMM
KF Case Study - brain damage from motorcycle accident which damaged STM
Impairment was mainly verbal and his memory for visual info was largely unaffected
Shows that there are separate STM components for visual (VSS) and verbal (phonological loop) info
How does Baddeley + Hitch 1975 support the WMM
Participant perform visual and verbal tasks together and performance on each was no worse when carried out separately
Who made the WMM and when
Baddeley and Hitch 1974
How does Lieberman 1980 show a weakness of the model
Visio-spatial sketchpad suggestd that all spatial info was first visual
Blind people have excellent spatial awareness though have never had any visual info
Should be separated into 2 different components
Weakness: there is a lack of ….. over …..
Lack of clarity over central executive
Capacity has never been measured
Baddeley said it was the “least understood component”
Not fully explained so working model is incomplete
How is the episodic buffer that was added in the 2000 a weakness
Temporary store that refers to how to recall info
Now includes LTM but didn’t have it before so was incomplete/didn’t fully make sense
