Working Memory Model - content Flashcards
What were Baddeley and Hitch’s criticisms of the Multi-Store Model of Memory
memory in unitary stores is too simplistic
focused more on STM - integral
what is STMs role in memory
actively used everyday when working / completing tasks
STM not unitary - has own subcomponents
what are the STM components
Central executive
Phonological Loop
Visuo Spatial Sketchpad
Episodic Buffer
what is the Central Executive
controls working memory
allocates functions to tasks
directs attention to tasks
what is the Phonological Loop
auditory store = rehearses sound based information
what is the Phonological Loop
(sub-components)
phonological store = retrieves info / holds it
articulatory loop = speech production for communication
what is the Visuo Spatial Sketchpad
visually organises info
what is the Visuo Spatial Sketchpad
(sub-components)
Visual Cache = stores info - visual items - shapes - colours
Inner Scribe = spatial organisation / awareness - arranging objects
what does BH think the components struggle to do
manage multiple tasks at once
- limited capacity
example of multiple tasks
2 visual tasks
- less successful if two at once compared to one at a time
one task = 2 components?
works just as effectively with 2 tasks working simultaneously
what is the episodic buffer
later added to the model
- storage
- all other components were processors
capacity?
holds information for a short period of time
- amnesiacs possessed info - post LTM damaged
encoding?
needs to be an episodic buffer that allows for information to flow to LTM
- limited duration / capacity
- integrates all info from components.
