Flashcards in Working memory model Deck (16):
Who came up with the working memory model?
Baddeley and Hitch
What are the 4 main components of the working memory model?
What is the WMM?
An explanation of how STM functions
How is the WMM different from MSM?
STM is non-unitary, with each component using different coding processes
What does the central executive do?
Monitors incoming data, makes decisions, and allocates tasks to sub-systems
What does the visuo-spatial sketchpad do?
Stores visual and spatial information - used for navigation or orientating
What did LOGIE subdivide the visuo-spatial sketchpad into?
- stores visual data
- records arrangement of objects in the visual field
What is the capacity of the visuo-spatial sketchpad?
Limited to about 3 or 4 objects
What does the episodic buffer do?
Temporarily stores information processed by other stores, sequencing them in time and acting as a link between STM and the wider processes of LTM/perception
When was the episodic buffer added to the model?
What does the phonological loop do?
Deals with auditory information, coding it acoustically in the order in which it arrives
What is the phonological loop subdivided into?
- stores the words you hear
ARTICULATORY CONTROL PROCESS
- allows maintenance rehearsal of verbal information, limited to 2 seconds
What is the clinical evidence to support the WMM?
KF - brain damage patient who struggled with verbal information but not visual
= NON-UNITARY STM
How did Baddeley prove the existence of separate components to process different info?
DUAL TASK PERFORMANCE
- ppts could carry out 2 tasks of DIFFERENT components significantly better than 2 tasks using the SAME component
= if a component has to carry out 2 tasks simultaneously, it slows down and makes mistakes SO separate systems must exist
Why are brain damage case studies not 100% reliable?
They are unique
= hard to tell if the effect can be generalised or is specific to an individual
