Working-Memory Model AO1

• Who proposed the WMM?

  Baddeley and Hitch (1974)
• What did Baddeley and Hitch theorise about the WMM?


  The STM is not just one store, but a number of different stores.
• How do the 4 components in the WMM vary?

  Qualitatively different in terms if coding and capacity
• What are the 4 components of the WMM?

  The CE, visuo-spatial sketchpad, phonological loop and episodic buffer
• What role does the CE play?

  • Supervisory: control, manipulates and processed information to and from its slave system
  • Gathers information from different sources and allocates brain resources on the task at hand, later organised between slave systems
• What information does the phonological loop deal with?

  Auditory
• What are the two components of the phonological loop?

  • Phonological store
  • Articulatory store
• How long does the phonological store hold information for?

  1.5-2 seconds
• What happens in the articulatory process?

  Auditory information undergoes maintenance rehearsal before moving to the phonological store
• List the three components of the visuo-spatial sketchpad?

  • Visual cache
  • Inner scribe
  • Kinaesthetic component
• What do the 3 components of the visuo-spatial sketchpad process?

  • Visual cache (the form/colour of an object)
  • Inner scribe (distance and relationship between objects)
  • Kinaesthetic component (movement)
• How many items do the visual cache and inner scribe hold each?

  3-4 items
• Who introduced the episodic buffer into the WMM?

  Baddeley (2000)
• What is the role of the episodic buffer?

  A general, modality free store of data; responsible for integrating data from the CE and transferring it into the LTM
