Working Model Of Memory Flashcards
who proposed the WMM?
Baddeley and Hitch
what is the central executive?
- monitors incoming data
- focuses and divides our limited attention
- allocates tasks to subsystems
what is the capacity, duration or encoding of the central executive?
- very limited processing capacity
- doesn’t store information
what are the subsystems that are allocated to tasks?
- phonological loop
- visuo-spatial sketchpad
- episodic buffer
what is the phonological loop?
- deals with auditory information
- preserves the order in which information arrives
what is the capacity, duration or encoding of the phonological loop?
- coding = acoustically
what is the phonological loop divided into?
- phonological store
- articulatory process
what is the phonological store?
stores the words we hear
what is the articulatory process?
- allows maintenance rehearsal(repeating sound or words in a loop to keep in working memory while they’re needed)
what is the articulatory process capacity?
2 seconds(worth) of what you can say
what is the visuo-spatial sketchpad?
- stores visual and or spatial information when required
(e.g. how many windows are in your house)
what is the capacity, duration or encoding of the visuo-spatial sketchpad?
limited capacity, 3 or 4 objects
who divided the visuo-spatial sketchpad?
Logie
what is the visuo-spatial sketchpad divided into?
- visual cache
- inner scribe
what is the visual cache?
store visual data
what is the inner scribe?
record the arrangement of objects in the visual field
what is the episodic buffer?
- temporary store of information
- integrating visual, spatial or verbal information processed by other stores
- maintaining a sense of time sequencing
what is the capacity, duration or encoding of the episodic buffer?
limited capacity of about 4 chunks
what does the episodic buffer link?
working memory to LTM and wider cognitive processes e.g. perception
what are the evaluations of WMM?
+ support from Shallice and Warrington’s case study on KF
+ studies of dual-task performance supports separate existence of visuo-spatial sketchpad
- lack of clarity over the nature of the central executive
what is the working model of memory?
explains how STM is organized and how it functions
when is the working model of memory active?
when we are temporarily storing and manipulating information
what can the episodic buffer be seen as in relation to the central executive?
- episodic buffer can be seen as a storage component of the central executive
