Memory: The Working Memory Model Flashcards
1
Q
What does the working memory model explain
A
- created by Baddeley and hitch
How STM is organised and how it functions - consists of 4 main components
2
Q
Outline the ‘central executive’ as a part of the WMM
A
- an attentional process that monitors incoming data, makes decisions and allocates slave systems to tasks
- central executive has a very limited processing capacity
3
Q
Outline the ‘phonological loop’ as a part of the WMM
A
- 1st slave system
- deals with auditory info + preserves the order in which the information arrives in
- subdivided into:
- the phonological store - stores the words you heard
- the articulatory process - allows maintenance rehearsal, the capacity of this rehearsal ‘loop’ = 2 seconds worth of what you can say
4
Q
Outline ‘the visual spatial sketchpad’ as a part of the WMM
A
- 2nd slave system
- stores visual and/ or spatial data
- limited capacity (Baddeley- 3-4 objects)
Logie subdivided VSS into 2 sub components: - the visual cache - stores visual data
- the inner scribe - records arrangements of objects in the visual field
5
Q
Outline the ‘episodic buffer’ as a part of the WMM
A
- 3rd slave system + added to the model by baddeley in 2000
- temporary store for info - visual spatial and verbal no processed by other stores
- the ‘storage component’ of the central executive
- limited capacity of around 4 chunks
- provides a ‘bridge’ between the WMM and the LTM
6
Q
What are the 3 evaluation points for the WMM
A
- supporting clinical evidence
- dual task performance studies support VSS
- lack of clarity over central executive
7
Q
Outline ‘supporting clinical evidence’ as an evaluation point for the WMM
A
- shallice and Warrington’s study on KF supports the WMM
- KF had poor stm ability for verbal info but could process visual info normally
- this suggests his phonological loop has been damaged, but other areas are still intact
- this supports the existence of a separate visual and acoustic store
8
Q
Outline ‘dual task performance studies support the VSS’ as an evaluation point for the WMM
A
- dual task performance studies support the separate existence of the VSS
- baddeley et al - showed ppts have more difficulty doing 2 visual tasks than doing both a visual and a verbal task at the same time
- this is because both visual tasks compete for the same slave system
9
Q
Outline ‘lack of clarity over central executive’ as an evaluation point for the WMM
A
- cognitive psychologists suggest this aspect of the WMM is unsatisfactory and doesn’t explain anything
- Baddeley also criticised the central executive for the same reasons
- the central executive needs to serve some purpose other than simply ‘attention’
- some psychologists believe it may consist of separate components
