Working memory model

• Working memory model


  Baddeley & Hitch
• STM


  Separate verbal and visual store
• Suggested STM had separate stores because If you do two visual things at the same time it's harder, but if you do a visual and verbal task it's no harder
• Active processing


  When we work on a task that requires you to store more information as you go along (instead of information passing through)
• Evaluation of Baddeley & Hitch's working memory model


  • Biological evidence for more than one store (Bunge et al.)
  • Support for different stores from brain damage patients
  • Support from dual task performance studies (Baddeley et al.)
  • Central executive is too vague
  • Real life application - learning difficulties - Alloway
