Working Memory Model WMM Flashcards
What are the criticism of the MSM
STM is not just one store but rather a number of stores
Baddeley and Hitch concluded that there must be many components to our STM as it still continues to function although some of it may be impaired
What is the order of the WMM
Central executive
Phonological loop
Visuo spatial sketch pad
Episodic buffer
What is the central executive
Supervisory component which have overall control
Limited capacity
Data arrives from the senses or LTM and it determines which components it is needed to process this
What is the phonological loop
Limited capacity (magic number)-preserves the order of information
Deals with auditory info (sound)
-Phonological store
Temporary holding place for verbal info based in speech form (perception)
-Articulatory process
Words repeated back as a form of maintenance rehearsal (production)
What is the visuo-spatial sketch pad
Limited capacity
Holding system for visual and spatial information
Helps you to plan how to get from one room to another
-Logie (1995) suggests that it’s divided into :
The visual cache (visual images)
The inner scribe (spatial relationship)
What is the episodic buffer
An extra storage to help store info that relates to both visual and acoustic info
Integrates info from all storage systems and also links it with info from LTM
Also has a limited capacity (magic number)
Added to the model in the year 2000
Working memory model evaluation (AO3)
P:one strength of WMM is that baddeley and hitch dual task strength supports the WMM
E:evidence for this is that they found that people are able to complete more than one task at once using their STM and the phonological loop alongside the visuo spatial sketch pad
E:this suggests that the model is reliable as it shows that there are different components to STM to facilitate with dual tasking as the WMM suggests
Working memory model evaluation (AO3)
P:however one weakness of the WMM is the central executive which is said to be too simple as it has no storage capacity
E:evidence for this is that it is argued that there is more going on in this this one component as EVR struggled with decision making but not a reasoning task
E:this questions the representation of the model as it suggest that the central executive is not favourable to a large sample of PPs
Working memory model evaluation (AO3)
P:contrastingly, another strength of the model is that evidence derived from brain damaged patients
E:evidence for this is that it was found that KF forgetting of auditory information was greater than visual in STM
E:this provides the model with validity as it relates to real and it shows how the model is from patients
Working memory model evaluation (AO3)
P:on the other hand a final weakness of WMM is that it questions the evidence that comes from brain damaged patient as these are case studies
E:evidence for this is that they don’t know if it’s the trauma that causes this difference as it can change your behaviour
E:this shows that it lacks reliability as we don’t know whether it is damage or trusts that affects brain damaged patients as we can’t tell
