2. Components

   • Central Executive

     • Function= direct attention to particular tasks
     • Has limited capacity so can't attend to too many things at once
   • Episodic Buffer
     • Baddeley (2000) added this store because he realised the model needed a general store.
   • Phonological loop

     • Deals with auditory information and preserves the order. Baddeley (1986) further subdivided this loop into phonological store and articulatory process
     • Phonological store holds words you hear like an inner ear. Articulatory process used for words that are seen and heard, these words are like an inner voice
