Working Memory Model (Page 28)

1. The model

   • Central Executive
     • Episodic Buffer
       • Long Term Memory
       • Added by Baddeley as he realised the model needed a general store
       • An extra storage system that has limited capacity
       • Integrates info from the other components
     • Visuo-Spatial Sketch Pad
       • Used when you have to plan a spatial task (e.g. getting from one room to another)
       • Visual (what things look like) and/or spatial (relationship between things) info is stored here temp
       • Logie suggested it could be split in 2
         • Visual cache (store)
         • Inner scribe (deals with spatial relations)
     • Phonological Loop
       • Deals with auditory info
       • Baddeley divided it into 2
         • Phonological store (inner ear)
           • Holds the words you hear
         • Articulatory process (inner voice)
           • Silently repeats the words you hear/see
     • The key component
     • The function is to direct attention to particular tasks, determining how 'resources' are allocated to taks
     • Limited capacity - can't attend too many things at once
