working memory model Flashcards
what is the working memory model illustrating?
STM
who proposed the working memory model?
Baddeley and Hitch (1974)
what are the stores included in the model?
- central executive
- phonological loop
- visuo spatial sketchpad
- episodic buffer
what does the central executive do?
- allocate slave systems to tasks
- monitor incoming data
what type of capacity does the central executive have?
very limited
what does the phonological loop do?
preserve the order auditory information arrives in
what two stores are included in the phonological loop?
- phonological store
- articulatory process
what does the phonological loop store?
words you hear
what does the articulatory process do?
control maintenance rehearsal
what does the visuo spatial sketchpad do?
store visual and spatial information
what are the two stores included in the visuo spatial sketchpad?
- visual cache
- inner scribe
what does the visual cache do?
store visual data
what does the inner scribe do?
record object arrangement in the visual field
what does the episodic buffer do?
- integrate visual, spatial and verbal information from other stores
- maintains time sequencing by recording events
- links to LTM
what are the main evaluation points for the working memory model?
1) research support from the KF case, Shallice and Warrington, and Baddeley
2) central executive lacks clarity (limited explanation)
3) brain scan study support from Braver et al - central executive may have physical reality in the brain
