Working Memory Model Flashcards
Who proposed the WMM?
- Baddeley and Hitch
Why was the WMM proposed?
- Baddeley realised memory was more complicated than the MSM made it out to be.
- Baddeley proposed WMM as something that carries out functions of STM and some of the work of LTM too
What is the visuo-spatial sketchpad?
- It allows us to recreated images either based on something we are seeing in real time or we have seen in pass.
What is the visuo-spatial sketchpad?
- It is a unitary store processing visual and spatial material together or whether these operations are carried out by separate stores
- Stores visual information
- 3/4 object capacity
What is central executive?
- It is the control center responsible for coordinating the other slave units
- It is able to process information from any of the senses and appears to have minimal storage capacity
- involved in problem solving and decision making
What 3 features does the central executive focus on?
- Focus attention
- Inhibition
- Shifting attention
CENTRAL EXECUTIVE - what is focus attention?
- Focus attention: attempting to do two things at the same time
CENTRAL EXECUTIVE - what is inhibition?
- concentration
CENTRAL EXECUTIVE - what is shifting attention?
- diving our attention between two tasks
What is the capacity of the central executive?
- limited capacity
What is the phonological loop?
- Deals with auditory information, especially for recall of words in the right order
- holds sounds for a few moments (2 second capacity), storing the sounds
What two components is the phonological loop composed of?
- The phonological loop store
- Articulatory process
What is the phonological loop store?
- (inner ear) - stores material presented audibly
What is the articulatory process?
- (inner voices) - constantly repeats or rehearses information so preventing forgetting by decay via maintenance rehearsal
What component was added later?
- Episodic buffer
- added by Baddeley in 2000
Why was the Episodic Buffer added?
- The central executive has no storage of its own and the other two stores hold either visual or auditory information
- Baddeley realised that there needed to be a store that could hold and coordinate information from all three other stores as well from LTM
where is the phonological loop located?
- Temporal Lobe
where is the visuo-spatial scratch pad located?
- in the right hemisphere
- simple tasks in occipital lobe
- complicated tasks in the parietal lobe
where is Episodic buffer located?
- hippocampus
where is the central Executive located?
- Frontal lobes
