M - The Working Memory Model Flashcards
why was the WMM made
as the multi store of memory model was too simplistic and could not account for everything we know about memory
what did Baddeley and Hitch say
the STM must have more than one component nd be involved in other processes than just storage
what does the WMM say
that 2 tasks can be carried out simultaneously in the STM provided they are dealt with by different parts
what does the WMM break down into
- central executive
- phonological loop
- visuospatial sketchpad
- episodic buffer (later)
what does the phonological loop break down into
- primary acoustic store
- articulatory process
what is the role of the central executive
- the control unit
- coordinates activity needed to carry out more than one process at a time
- processes all sensory forms
what is the role of the articulatory process (inner voice)
- words are maintained by subvocal repetition
- produces speech
- limited capacity
what is the role of the primary acoustic store
- temporary storage for recently heard words
- perceives speech
- limited capacity
what is the role of the visuospatial sketchpad
- writing pad for visual data
- helps you interact and navigate your physical environment
- limited capacity
why was the original model of the WMM criticised
only focussed on the STM
- added the episodic buffer in 2000
what is the role of the episodic buffer
introduced to explain how we temporarily sotre information combined from
- central executive
- phonological loop
- visuospatial sketchpad
- LTM
evidence for the WMM (Logie, 1989)
M: pts play a game and at the same time have a visuospatial task or verbal distractor task
R: VS task impaired performance of spatial motor, VM task disrupted verbal elements of the game
C: demonstrates that each part has its own role
strengths of WMM
- extremely influential to many cognitive psychologists
- more plausible than the MSMM
- useful the help the understanding of learning differences
weaknesses of WMM
- exact role of central executive is unclear
- research is generated/artificial tasks
- if affects children’s learning of phonics in school
