WMM

• Working Memory Model

  Developed by Baddeley and Hitch, focusses on short-term storage of info and says STM isn't a unitary store
• Working Memory Model

  • Central Executive - monitors incoming data and allocates to 'slave systems'
  • Phonological Loop - processes audio info, split into Phonological store (words you hear) and Articulatory process (repeats sounds while needed)
  • Visuo-Spatial Sketchpad - processes visual and spatial info, split into Visual cache (visual data) and Inner scribe (arrangement of objects in visual field)
  • Episodic Buffer - integrates info and maintains time-sequencing (records events)
• Strength of WMM

  KF had poor auditory STM but good visual STM, showing proof of separate stores
• Strength of WMM

  Baddeley et al did research into dual task performance. Participants who did a visual and verbal task had good results. When both tasks were visual/verbal results declined, because the tasks are competing for space in a slave system.
• Weakness of WMM

  Central executive is too vague, EVR had a cerebral tumour removed and did well on reasoning tasks but bad on decision-making, suggesting some of his CE worked and some didn’t
