The working memory model Flashcards
Who developed the working memory model?
Baddeley & Hitch (1974)
Name the components of the WMM?
Central executive
phonological loop
visuo-spatial sketchpad
episodic buffer
LTM
What is the function of the central executive?
Monitors and coordinates all other mental functions working in memory - directs attention
What does the phonological loop do?
Deals with auditory information - divided into the inner ear (holds the words you hear) and an inner voice (words silently repeated - form of maintenance rehearsal)
What does the visuo-spatial sketchpad do?
Processes visual and spatial information
What did LOGIE suggest the visuo-spatial sketchpad could be divided into?
1) a visual cache which stores information about visual items
2) an inner scribe which stores the arrangement of objects in the visual field
What is the function of the episodic buffer?
An extra storage system that integrates all the components and links to the LTM
What are three evaluation points of the WMM?
- Evidence from brain-damaged patients (SHALLICE & WARRINGTON - studied KF - had impaired verbal STM but intact visual memory after brain damage - demonstrates the phonological loop and visuo-spatial sketchpad are separate - increases ecological validity) - what about trauma of individual? or their previous characteristics?
- Vague - the CE does not really explain anything - likely to be more components (ESLINGER & DAMASIO - study of EVR - had a cerebral brain tumour removed - still had good reasoning skills suggesting his CE was in tact but had poor decision making skills suggesting CE was not wholly intact)
- More detailed than the MSM, breaks down STM rather than treating it as a unitary store - offers a more nuanced and flexible approach to understanding memory
