- Working Memory Model
- Created as the MSM was too simplistic
- STM is active and has more than one component
- Central Executive
- Controls and coordinates operations of subsystems
- Decides direction of attention (to inputs)
- Cannot attend to many things at once
- Limited/No capacity
- Encoding is modality free
- No specific way of encoding
- Connects working memory with LTM
- Phonological Loop
- Primary Acoustic Store
- 'The Inner Ear'
- Holds speech based information for a few seconds
- Articulatory Loop
- 'The Inner Voice'
- Used to rehearse verbally, using info from PAS
- Used to maintain memory traces
- Paulesu Study
- Participants either store a series of letters
- Or mentally rehearse sounds of letters
- PET scan measured blood flow throughout
- Or mentally rehearse sounds of letters
- Two tasks were associated with blood flow patterns in different brain areas
- Participants either store a series of letters
- Primary Acoustic Store
- Episodic Buffer
- Late addition to model
- Limited capacity
- Binds verbal, visual, spatial and chronological info
- Information from each subsystem can interconnect
- Visuo-Spatial Sketchpad
- Holds visual information
- Features, what things look like
- EG. Shape, colour, size
- Features, what things look like
- Holds spatial information
- Locations, movements etc.
- EG. Used when planning way through shop
- Locations, movements etc.
- 'The Inner Eye'
- Baddely Study
- Track a moving spot of light
- Same time, classify angles in 'F' as including bottom or top line
- Difficult to follow track and complete imagery task
- Tracking and imagery tasks compete for resources in VSSP
- Limited capacity in VSSP
- Tracking and imagery tasks compete for resources in VSSP
- Track a moving spot of light
- Holds visual information
- Created as the MSM was too simplistic
