The working memory model Flashcards
Who developed the working memory model?
Baddeley & Hitch (1974)
What are the 4 main components of the WMM?
Central executive, episodic buffer, visuospatial sketchpad & phonological loop
What does the visuospatial sketch pad deal with?
The visuo-spatial sketch pad (INNER EYE) deals with visual and spatial information.
What is the phonological loop broken down into?
Phonological store (inner ear) and Articulatory loop (inner voice)
What is the role of the episodic buffer?
To provide a general storage facility, holding and combining information not only from the visuo-spatial sketch pad, phonological loop and central executive (STM), but also from LTM
What is the role of the central executive?
It controls and coordinates the operations of the OTHER components. It decides which information is attended to and which parts of the working memory to send that information to.
Why was the WMM developed?
In an attempt to consider the possibility of there being more than one part to STM.
Who provided research support for the visuospatial sketchpad?
Logie et al (1989)
Who provided research support for the phonological loop?
Paulesu et al (1993)
What do the supporting pieces of evidence suggest about these stores?
If you carry out two verbal or two visual tasks at the same time you do them less well than if you did them alone, however if you carry out one verbal and one visual task you do them as well as when you do them alone. This suggests that STM contains separate stores for verbal and visual information
How does the case of KF support the WMM?
After his brain injury, KF had poor STM ability for auditory (sound) information but could process visual information normally.
What is the main issue with the central executive?
The central executive is the most important but the least understood component of working memory
