Working Memoery Model

• Strength evidence in brain damaged pts

  Shallice and Warrington - KF

  ST forgetting of auditory info much greater than visual stimuli

  Auditory probs limited to verbal material eg letters and digits not meaningful sounds

  Brain damage is retricted to the phonological loop

  Shows STM has separate stores

  However brain injuries are traumatic changed behaviour itself so individals perform worse on certain tasks.
• Central exec too simple


  Study on EVR cerebral tumour removed he performed well on testing reasoning showing central exec was intact however he made poor decision making suggests it wasn;t intact

  Central executive has more components that currently understood

  Too vague
