The working Memory Model Flashcards
Who came up with the WMM?
Baddeley & Hitch
what is the WMM?
Explanation of how STM is organised and how it functions
What is the WWM concerned with?
The ‘mental space’ that is active when we are temporarily storing and manipulating information.
what’s the central executive and its role?
- ‘supervisory’ role
- monitors incoming data
- allocates sub systems to tasks
- divides our limited attention
Capacity of the central executive
very limited
What’s the phonological loop and its role?
Subsystem that deals with auditory info
Coding and Capacity of the phonological loop
Coding= Acoustic
Capacity= 2 seconds of speech
What is the PL divided into?
Phonological store= stores the words you here
Articulatory process= allows maintenance rehearsal (repeats sounds)
What’s the visuo-spatial sketchpad divided into?
Visual cache= stores visual data
Inner scribe= records arrangement of objects in the visual field
Coding and Capacity of the Visuo-spatial sketchpad?
Coding= visual
Capacity= limited, 3 or 4 objects
What’s the visuo-spatial sketchpad and its role?
Subsystem that stores visual information
What’s the episodic buffer and its role?
- Integrates data from subsystems
- Records order of events
- Linked to LTM
Coding and Capacity of the Episodic buffer?
Coding= flexible
Capacity= 4 chunks
EVAL: WMM (strengths)
+ Clinical evidence
- KF had poor auditory memory but good visual memory
- Damaged PL but VSS intact
- strongly supports existence of separate visual & acoustic memory stores
CA: KF may have had other impairments that affects his WM
+ Dual-task performance
- Difficult to do 2 visual tasks (or 2 verbal) at same time
- but one visual and one verbal is fine (Baddeley et al)
EVAL: WMM (Limitations)
Nature of the central executive
- lack of clarity over the nature of the CE
- needs to be more clearly specified than just being simply ‘attention’
- This challenges the integrity of the WMM
