• introduction

  • Baddeley & Hitch
  • short-term memory has multiple components
• A01

  • Central Executive - attention control, suppressing irrelevant information, allocating tasks to slave systems, limited capacity
  • Phonological Loop - auditory and verbal information
  • phonological store: spoken words
  • articulatory system: subvocal rehearsal
  • Visuo-Spatial Sketchpad - visual and spatial information
  • visual cache: form and colour
  • inner scribe: spatial and movement
  • Episodic Buffer - temporary storage, integrates information, links to long-term memory, conscious awareness
• A03

  • dual-task studies
  • Baddeley & Hitch found difficulties so STM isn't a unitary store
  • clinical evidence
  • Shallice & Warrington found KF had separation between phonological loop and visuospatial sketchpad, high validity
  • lacks clarity
  • central executive may have subcomponents, oversimplification
