- Working Memory Model
- Central Executive
- Acts as a manager
- co-ordinates the slave systems
- Focuses attention levels to each system
- Braver and Richardson claimed there was a lack of clarity over its exact capacity
- Braver gave participants a task involving the CE - more activity in the PFC with harder tasks
- Eslinger: patient with cerebral cortex caused decision making problems, but did well on reasoning tasks - different effects
- Phonological Loop
- Phonological Store
- Speech perception
- Words need to be verbalised
- Holds snippers of sounds from environment
- Inner ear
- Stores for 20-30 seconds
- Acoustic coding
- Articulatory Control Process
- Duration: 2 seconds worth of your 'talking'
- Rehearses sound from the store
- Inner voice
- Small capacity
- In articulatory code
- Speech production
- Maintenance rehearsal
- Larsen - Phonological Similarity Effect (decreased 25%)
- Baddeley - word length effect
- Paulesu - letters = sound = inner ear, numbers = items = inner voice
- Phonological Store
- Episodic Buffer
- Added in 2000
- Brings information from all components
- Up to 4 chunks
- Backup store
- Forms memories
- Visuo-Spatial Sketchpad
- Inner Scribe
- records the arrangement of visual objects in a visual feed
- Navigation
- Move and manipulate images
- Visual Cache
- Stores visual data
- Images fade quickly
- Dual task Performance -worse with 2 visual tasks
- Lieberman: blind people are still aware
- Inner Scribe
- Model
- Short-term memory
- Explains why we can do some tasks together, but not others
- 1974, Baddeley + Hitch
- Baddeley: gave participants a task to occupy central executive, articulatory control process or both - slower at tasks involving both - shows limited capacity
- Shallice and Warrington: KF could recall words better when read rather than when spoken
- Does not explain how musical memory fits in
- Central Executive
