Components
- Central executive
- Phonological Loop
- Visuo-spatial Sketchpad
- Episodic Buffer
- LTM
Central Executive
Coordinates incoming information and allocates it and tasks to other components of WMM (the slave systems)
Phonological Loop
- Processes auditory information (including written).
- Articulatory Process - maintenece rehearsal loop
- Phonological Store - words you hear
Visuo-Spatial Sketchpad
- Processes visual and spatial information
- Visual Cache - visual data
- Inner Scribe - arrangement of objects
Episodic Buffer
- Integrates material from other subsystems
- Bridge to LTM
Evaluation Points
+ Evidence of multiple stores from Case Study of KF (performed well of reading task but badly on listening)
+ Support from Baddeley's Dual-Task research showing different stores (performance on 2 listening tasks was poor but losteing and visual task performance was good)
- Unclear nature of Central Executive
