Working Memory Model

Working Memory Model

1. Short-term memory

2. Baddeley and Hitch 1974

3. Central Executive

   • "Supervisory" role
   • Monitors incoming data, focuses and divides our limited attention and allocates subsystems to tasks
   • It has a very limited processing capacity and doesn't store info

4. Phonological Loop

   • Deals with auditory info and preserves the order in which the info arrives
   • Phonological store is the store which stores the words you hear
   • Articulatory process which allows maintenance rehearsal
     • The capacity of this loop is around two seconds worth of what you can say

5. Visuo-spatial sketchpad

   • Stores visual and/or spation info when required
   • Visual cach stores visual data
   • Inner scribe record the arrangement of objects in visual field
   • Limited capacity which is about three or four objects

6. Episodic Buffer

   • Added in 2000 by Baddeley
   • Temporarily stores info of events which are happening and maintains a sense if tune sequencing
   • Seen as storage component of CE and has limited capacity of around 4 chunks
   • Links STM to LTM and wider cognitive processes such as perception
