Working memory model

• WMM Baddeley & Hitch)

  -central executive- coordinates actions, directs attention, capacity of 4
• WMM Baddeley & Hitch) Phonological loop- coding: acoustic capacity: limited

  -processes auditory info

  Phonological store (inner ear) -stores words that are heard

  Circulatory control system- allows for vocal repetition, capacity determined by word length
• WMM Baddeley & Hitch) Visuo spatial sketchpad

  -stores visual & spacial info & allows for navigation, capacity determined=3/4 objects

  -Logie- found visual cache:color & size inner scribe:arrangement of objects
• WMM Baddeley & Hitch) Episodic Buffer- back up storage
• WMM Ao3) More detailed that MSM

  -shows that STM is not a unitary store

  -more developed e.g spatial & visual processing, problem solving
• WMM Ao3) Weakness

  -only STM is explained, LTM is ignored & vague

  -Central executive isn’t explained in depth, like what is its role in attention
• WMM Ao3) Lieberman argues VSS should be 2 separate stores

  -it implies all spatial info was first visual

  -however blind people have good spatial awareness although they have no visual info
