The working memory model

The working memory model

1. Central executive

   • Allocates tasks to slave systems
   • No storage

2. Phonological loop

   • Phonological store holds words for the PL
     • Inner ear
   • Articulatory process performs maintenance rehearsal for PL
     • inner voice

3. Visuo-spatial sketch pad

   • Visual cache for form and colour
   • Inner scribe for spatial relations

4. Episodic buffer records events as they happen

5. Evaluation

   • Word length effect
     • Longer words can't be rehearsed (supports phonological loop)
       • Articulary suppression task cancels out word length effect (supports articulatory process)
   • CE doesn't explain anything and more complex than currently represented
   • Hitch and Baddeley
     • participants slower when doing dual tasks
   • Brain damaged patients
     • KF damage to PL problems with verbal material (words not sounds
     • LH damage to spatial system
     • SC damage to PL unable to learn word pairs presented out loud
