- Working Memory Model (WMM)
- The Central Executive
- Believed to be the most important part of the model
- This controls and directs the attention to the suitable component/s
- Allocates the resources to either the auditoary or visual store
- Extremely limited capacity and duration
- Only holds information for a maximum of 2 seconds
- Visual-spatial Sketchpad
- Visual Cache
- Limited capacity
- Stores visual/spatial info
- Inner Scribe
- Rehearsal mechanism for info
- Visual Cache
- Phonological Loop
- Phonological Store (Inner Ear)
- Has a limited capacity of 1-2 seconds
- Articulatory Control Process (Inner Voice)
- Rehearses auditory verbal information from the phonological store
- Has a short capacity of 1.5 - 2 seconds if not rehearsed
- Rehearsed subvocally so is remembered
- Holds spoken info
- Phonological Store (Inner Ear)
- Supporting Evidence
- Phonological Loop (Research)
- Baddeley et al
- Showed one group of Pps 5 one syllable words
- Correctly recalled more of the shorter words
- Showed one group of Pps 5 polysyllabic words
- Correctly recalled more of the shorter words
- Showed one group of Pps 5 polysyllabic words
- Supports the theory that is has a very short capacity and duration
- Polysyllabic words take longer to rehearse
- Case Study of KF
- Recieved brain damage from a motorcycle accident
- His STM was damaged - only had a digit span of 1
- Remembered words better if presented visually rather than acoustically
- Visual-spatial sketchpad separate to phonological loop
- Phonological Loop (Research)
- Limitations of WMM
- Weaknesses in evidence
- Many of the key evidence for the WMM comes from case studies into patients with brain damage
- A brain damaged brain is not normal and does not function the same as a normal brain
- Researchers can not be sure whether the effected memory is down to damaged brain or if the traumatic accident also contributed
- Many of the key evidence for the WMM comes from case studies into patients with brain damage
- Weaknesses in evidence
- The Central Executive
