• what is the working memory model

  suggest that STM has subdivisions
• what is the central executive

  control mechanism with a supervisory role to monitor incoming data

  co-ordinates the activities of the three subsystems in the memory

  very limited storage, capacity and duration
• what is the phonological loop

  processes auditory information and preserves the order in which the information arrives

  subdivided into:

  phonological store: passive store, holds words you hear

  articulatory control system: active processor, allows maintenance rehearsal

  capacity is believed to be two seconds worth of what you can say
• what is the visa-spatial sketchpad

  stores visual and spatial information when required. colour, position, texture and what something looks like.

  Logie subdivided VSS: visual cache and inner scribe

  limited capacity (baddeley 3 or 4 objects)
• what is the episodic buffer

  temporary store for information

  integrates visual, spatial and verbal information from other stores

  maintains sense of time sequences

  links working memory to LTM and wider cognitive processes such as perception
