Working memory components (Baddeley’s model)

Working memory components (Baddeley’s model)

1. Phonological loop

   • Phonological loop phenomenas
   • Phonological store
     • limited capacity
     • rapid decay
       • holds info for only a few seconds
   • Articulatory rehearsal process
     • recite the info in the phonological store, in order to prevent this very rapid decay
       • constantly refreshing the material
     • '' tape loop or tape recorder with a 2-second duration''
   • Holds verbal and auditory info

2. Visuospatial sketch pad

   • Visuospatial sketch pad
   • Holds visual and spatial info

3. Central executive

   • Central executive
   • where the major work of working memory occurs.
   • ''Traffic cop''
   • Uses attention to coordinate between phonological loop/visuospatial sketchpad
     • Divided attention
