the working memory model Flashcards
what is the role of the central executive?
- process that monitors incoming data
- allocates info to slave systems
what is the capacity of the central executive?
-limited processing capacity
give an evaluation point for the central executive?
WEAKNESS
- lack of clarity
- believed to need more clarification
- believe it consists of many components
what is the Phonological loop + role?
- deals with auditory info
- stores words we hear
what is the capacity of the Phonological loop?
- limited
- rehearsal capacity = 2 seconds
give evaluation for the Phonological loop?
STRENGTH
- KF had brain damage
- could process visual info but not verbal
- suggests the Phonological store was damaged
- supports the separate store in loop
why may evidence of KF not be reliable and what for?
WEAKNESS
- the Phonological loop
- he was brain damaged and therefore abnormal
- may not be reliable
what is and role of visual-spatio sketchpad
- stors visual info
- visual cache: stores visual data
- inner scribe: records object arrangement
give evaluation for visual-spatio sketchpad?
STRENGTH
- dual performance supports separate existence of sketchpad and loop
- pp found it hard to do 2 visual tasks than a visual and verbal task simultaneously
- shows slave system is limited capacity and competition for space
- therefore 2 different slave systems
what is role of the episodic buffer
- added recently to model
- links working memory to LTM through rehearsal
what are the key sections of the WMM?
- central executive
- phonological loop
- visual-spatio sketch pad
- episodic buffer
what are the two stores in the -visual-spatio sketch pad?
- inner scribe
- visual cache
what are the two stores in the phonological loop?
- articulatory control system
- phonological store
