The working memory model

• Baddeley and Hitch's working memory model (WMM)


  Describes short-term memory (STM) as a storage system with multiple components rather than a single unitary store as described in the multi-store model of memory
• Working memory model (WMM)

  • Central executive (CE)
  • Phonological loop (PL)
  • Visuo-spatial sketchpad (VSS)
  • Episodic buffer
• Central executive (CE)


  An attentional system that allocates information to the appropriate slave systems
• Phonological loop (PL)


  Deals with acoustic information and has two components: the phonological store and the articulatory control process
• Visuo-spatial sketchpad (VSS)


  Temporarily stores visual and spatial information
• Episodic buffer


  Allows sound and visual information to be bound together and experienced as a single episode
