WMM

1. Central executive

   • controll centre
   • data from the senses
   • Decides how attention is directed
   • Coordinates actions of other components
   • Can process information from any sensory modality (semantic, auditory, visual)

2. Visuospatial Sketchpad

   • Limited capacity
   • Can rehearse information
   • Temporary memory system for holding visual and spatial information
   • manipulates information from the eyes or the LTM

3. Phonological loop

   • limited capacity
   • used to rehearse info
   • auditory information and preserves word order
   • baddeley(1968) subdivided it into phonological store and articulatory store

4. Episodic Buffer

   • combines information from other areas
   • Extra storage system
   • limited capacity
   • baddeley(2000) added this once he realised that the model needed a more general store.
   • CE has no storage capacity

5. Baddeley and Hitch (1974)

   • believed that the msm was over simplified
   • believed the stm was not a unitary store but was made up of several
   • They saw LTM as a more passive store that holds previously learned material for use by the Stm when needed

6. supporting studies
