Working Memory Model Flashcards
What are the 4 main stores
central executive, phonological loop, Visuospatial sketch pad, episodic buffer
What is the function of the central executive
Giving attention to information from the other two stores making decisions about what’s most important also deals with cognitive tasks such as mental arithmetic and problem solving.
Limited capacity
What is the function of the phonological loop
Phonological store inner ear holds information in a speech based form
Has limited capacity
Articulatory control process (inner voice) – Linked to speech production. Used to rehearse and store verbal information from the phonological store.
What is the function of the Visio spatial sketch pad
Visuo-Spatial Sketchpad (inner eye): Stores and processes information in a visual or spatial form. The VSS is used for navigation.
What is the function of the episodic buffer
The episodic buffer acts as a ‘backup’ store which communicates with both long term memory and the components of working memory.
What are some negatives of working memory
Only looks at short term memory
Very little is known about the central executive
What are some positives of the working memory model
Practical applications- dyslexia help with reading and writing
Shows not unitary
The KF Case Study supports the Working Memory Model. KF suffered brain damage from a motorcycle accident that damaged his short-term memory. KF’s impairment was mainly for verbal information - his memory for visual information was largely unaffected.
Does not over emphasis reherhasal
Who proposed the working memory model?
