1. STM

2. Central Executive

   • Direct attention to tasks
   • Determine how slave systems are allocated
   • No storage capacity
   • Makes decisions

3. Phonological Loop

   • Deals with auditory information and preserves word order
   • Baddeley 1986
     • Phonological store
       • Holds words heard
     • Articulatory process
       • Holds words heard/seen and silently repeats them

4. Visio-Spatial Sketchpad

   • Visual and/or spatial information stored here
   • Limited capacity
     • According to Baddeley: 3/4 objects
   • Logie 1995
     • Visuo cache store
       • Stores visual data
     • Inner scribe
       • Records arrangements of objects in the visual field

5. Episodic Buffer

   • General store
   • Limited capacity of about 4 chunks (Baddeley 2012)
   • Added in 2000
   • Integrates information from all other areas
   • Can be seen as the storage component of the central executive
