- Working Memory Model
- Episodic Buffer
- General store for acoustic/visual info
- Limited capacity
- Bridge between WM and LTM
- Phonological loop
- Deals with auditary information
- Inner ear/inner voice
- Limited capacity
- Central Executive
- Directs attention
- Allocates resources
- Limited capacity
- Visuo-spatial sketchpad
- Holds visual/spatial info
- Example: thinking about your route to school
- Model of STM
- Evidence
- KF- after motorbike accident, presented with series of numbers, could only recall 2. Verbally presented numbers, recalled more. Supports idea of multiple stores
- Bunge- had to read sentence and recall final word. More brain activation in dual task conditions rather than single. Evidence for limited capacity of STM.
- Evaluation
- S: Applies to real life tasks e.g. reading, explains more than MSM, explains STM in terms of temporary storage/active processing, research support from dual task studies where we show impaired performance.
- W: not a lot of info about CE- decreases validity(incomplete explanation), doesn't take into account practise time-says tasks are always easy/difficult, unsure of cause/effect: key evidence comes from studies of individuals with brain damage
