Working memory model

• Working memory model: A representation of short-term memory. It suggests that STM is a dynamic processor of different types of information using subunits co-ordinated by a central decision-making system.
• Central executive: The component of the WMM that co-ordinates the activities of three sub-systems in memory. It also allocates processing resources to those activities.
• Phonological loop:

  • Deals with auditory information and preserves the order in which it arrives.
  • Phonological store: Stores the words you hear.
  • Articulatory process: Allows maintenance rehearsal.
• Visio-spatial sketchpad:

  • Stores visual/spatial info.
  • Visual cache: Stores visual data.
  • Inner scribe: Records arrangement of objects in the visual field.
• Episodic buffer:

  • Temporary store of information.
  • Intergrates info from other stores, recording episodes.
  • Can be seen as the storage component of the CE.
  • Links WM to LTM
