• the working memory model was proposed by Baddeley and Hitch.
• It suggests that the STM can be broken down into 4 smaller subcomponents.

  • episodic buffer
  • central executive
  • phonological loop
  • visuospatial sketchpad
• central executive

  • distributes tasks to the slave systems
  • deals with info coming from every sense
  • limited capacity
  • cant store information
• phonological loop

  • deals with auditory information
  • limited capacity
  • has two smaller subcomponents - phonological store and articulatory control system
  • phonological store stores spoken words (inner ear)
  • articulatory control system stores written words (inner voice)
• visuospatial sketchpad

  • deals with visual information
  • limited capacity
  • smaller subcomponents- inner scribe, visual cache
  • inner scribe stores arrangement of objects within the field of view (inner eye)
  • visual cache stores visual data (colours)
• episodic buffer

  • maintains a sense of time sequencing
  • limited capacity
  • temporary store
