Working Memory Model (Memory) Flashcards
(8 cards)
1
Q
Baddeley and Hitch 1974
A
- Cognitive model of information processing
- Created WMM to replace the STM store in MSM
- WMM an active prcessor model of multiple stores (STM a passive and unitary store)
2
Q
The Head of the Model and the 3 Slave systems
A
Central Executive
Phonological Loop
Visuo-Spatial Sketchpad
Episodic Buffer
3
Q
Central Executive
A
- Receives sense information, controls attention & filters before passing on the subsystems
- Limited capacity
- Manages slave systems
4
Q
Phonological Loop
A
Processes auditory information (acoustic coding)
Capacity of 2 seconds
5
Q
Visuo-spatial Sketch Pad
A
Processes (codes) visual and spatial information
Limited capacity
6
Q
Episodic Buffer
A
Added to WMM in 2000 as model needed generalised store to hold and combine info from CE,PL,VSS and LTM
Limited capacity
7
Q
Positive Evaluations of WMM
A
- Baddley - Participants asked to do two visual tasks or a visual and verbal task
Found performance was much better when the tasks were not using the same processing
Suggests the VSS and PL are separate systems
- WMM more accurate than STM component of MSM in describing how memory is used as an active processor
8
Q
Negative Evaluation of WMM
A
Studies into memory lack mundane realism making findings ungeneralisable to day to day life
