Working Model of Memory

Working Model of Memory

1. Central Executive

   • Controls attension

2. Visuo-spatial sketchpad

   • holds information we see
   • spatial information
   • limited capacity

3. Phonological Loop

   • Articulatory Control System
     • Mental rehearsal
     • inner voice
   • Phonological Store
     • sound based information code to store information
     • inner ear

4. Episodic Buffer

   • Provides time sequencing for visual, spatial and verbal information
   • perhaps a storage space for the central executive

5. Strengths

   • expands of MSM
   • explains ideas of the 'inner ear' and 'inner voice'
   • explains data from neurophysiological evidence

6. Weakenesses

   • episodic buffer needs to be explained further
   • findings lack validity - artificial tasks
   • model has been added to which means it was inadequate and was not valid
