Working Memory Model Flashcards
1
Q
Who proposed the working memory model and describe what it is (Intro)
A
- Baddeley and Hitch proposed the WMM as an exp of how STM works
- They said STM was not a unitary store like the MSM but infact had several different stores which are all connected but work independently as an active processor
- It views memory as active rather than passive in contrast to the MSM
- If a person completes two tasks at the same time using the same slave system, performance will be reduced as they have a limited capacity, but not if tasks use diff slave systems as there is no competition for limited capacity
- Composed of central executive, phonological loop, the visuo - spatial sketchpad and the episodic buffer

Q
Describe what is meant by the central executive
A
- attentional process that monitors incoming info and can code any type of info
- decides what needs to be done and delegates tasks accordingly to slave systems
- takes over most demanding tasks where necessary
- any task that is new or requires conc will overload the c.e as it has very limited capacity

Q
Describe what is meant by the phonological loop
A
- auditory info is passed from CE to PL
- limited capacity and codes acoustically
- baddeley subdivided PL into two parts
- phonological store = stores words we hear like an inner ear
- articulatory loop = silently rehearses words that are seen or heard to keep in memory, like an inner voice
4
Q
Describe what is meant by the visuo spatial sketchpad
A
- all visual info is passed from the CE to the VSS, like an inner eye
- responsible for setting up mental images and used for spatial tasks e.g. giving directions
- temporarily stores visual and spatial info
- limited capacity and codes visually
- divided into 2 parts
- visual cache = stores visual data
- inner scribe = records arrangement of objects in visual field
5
Q
Describe what is meant by the episodic buffer
A
- general store later added by baddeley and hitch
- limited capacity and can code any type of info
- collects and combines info from all stores to record an event/episode
- transfers info to the LTM and retrieves info from the LTM to the STM

Q
What are the three AO3 PEELS to evaluate the working memory model?
A
RTS by patient KF
Discussion - low pop val
Strength - dual task performance
