- Memory: Working Memory Model
- Central Executive: allocates stimuli to the different sections)
- Phonological Loop
- Phonological Store: Store speech or sound related information (inner ear)
- Articulatory Control System: Process for rehearsing information (inner voice)
- Visuo-Spatial Sketchpad: manipulates visual information and creates spatial awareness (inner eye)
- Phonological Loop
- KF Case Study
- Brain damage due to a motocycle accident
- No LTM problems, but can only remember 2 items at a time
- Forgot auditory stimuli more than visual stimuli
- Suggests that there are multiple STM stores
- EVALUATION
- Case study -> can investigate situations where it would be unethical to engineer them
- Case study -> focus on one person -> lacks population validity -> can't generalise
- Baddeley et al (1973)
- 'Dual Task' study
- Simple tracking task at the same time as a visual task
- Following a spot of light whilst imagining a block F and saying whether the light matches up with the corners
- Then given a tracking task with a verbal task
- Simple tracking task at the same time as a visual task
- Two visual tasks were difficult
- Visual and verbal task successful
- Two visual tasks both use same part of STM (visuo-spatial sketchpad)
- Visual and Verbal task used different parts so could be done successfully
- EVALUATION
- Lacks ecological validity -> artificial setting -> can't generalise
- 'Dual Task' study
- Central Executive: allocates stimuli to the different sections)
