Working Memory Model Flashcards
What is the working memory model
It is a representation of STM. It suggests that STM is a dynamic processor of different types of information using sub-units coordinated by a central decision-making system.
What is the Central Executive
It is the component of the WMM that coordinates the activities of the three subsystems in memory. It also allocates processing resources to those activities
What is the phonological loop
It is the component of the WMM that processes information in terms of sound. This includes both written and spoken material. It’s divided in the phonological store and articulatory process.
What is the visuo spatial sketchpad
It is the component of the WMM that processes visual and spatial information in mental space often called our inner eye.
What is the episodic buffer
It is the component of the WMM that brings together material from the other subsystems into a single memory rather than separate strands. It also provides a bridge between WM and LTM
What are assumptions abou the approach of the WMM
Baddeley and Hitch suggest a more complex and dynamic STM than the MSMs version.
● It has several but connected parts, unlike the single STM store of the MSM.
● It is an active system. It allows us to work things through, like mental arithmetic, but has a limited capacity.
● The model consists of four main components: Each of which are qualitatively different - especially in terms of capacity and coding.
Who were the psychologists that developed the WMM
Baddeley and Hitch
What is the central executive known as
The BOSS od rhe working memory model as it controls the whole system
What does the central executive control
Attention and directs information to the two slave systems
What is the capacity of CE
Very limited
What does PL deal with
Auditory info and preserved info order
What are the 2 parts of PL
Phonological store and articulatory process
What is the phonological store
Stores acoustic items for a short period of time
What is the articulatory process
It allows maintenance rehearsal, repeating words to keep them jn the WM
What is the capacity of PL
2 seconds worth of what u say
What does the visuo spatial sketchpad deals with
Visual and spatial tasks
What are the 2 subcomponents of VSS
Inner scribe and visual cache
What is the inner scribe
It deals with the spatial relationship between objects
What is the visual cache
It stores visual information
When was the episodic buffer added to the model
In 2000
What does the EB do
Binds all the information together and sends it to the LTM
Why did Baddeley add the EB
Because he realised that the model had no general storage facility
What was the theory behind the WMM
Dual task performance, it illustrates tgat there is no interference when 2 tasks are being performed together
What was observed with with the dual task performance
If both were visual, each task was reformed slower compared to if one was visual and one was auditory
What are the strengths if WMM
.patient study on KF supported the existence of separate visual and acoustic stores
.dual task performance provides evidence for visuospatial sketchpad
What is a limitation of WMM
.lack of clarity
.cog psychologists don’t think this model really explains anything
.evidence from brain damaged patie to to always reliable as ut is a unique case
