Working Memory Model

Working Memory Model

1. Saw STM as an active store

2. Focus of the cousciousness

3. explanation of MSM

4. Central Executive

   • Visuo-spatial sketchpad
     • Slave system
   • Episodic buffer
   • Phonological loop
     • slave system

5. Multi component

6. CE

   • Oversees and coordinates the wm
   • filters what is recieved by organs and what's ignored
   • processes info and sends to slave systems and collects responses
   • limited in capacity
   • balances attention between tasks
     • talking whilst driving
   • Can only have one type of info at a time
   • Evalutation
     • no proofs, just statements
     • Little is known about CE
     • Understood as something to control attention

7. PL

   • deals with the auditory info
   • Primary acoustic store: inner ear stores words recently heard
   • Articulatory process: keeps info in PL through sub vocal repetition and is linked to speech production
   • Evolution of human vocal language
   • case study of man w brain damage - functioning PL but not VSS
     • separate slave systems

8. VSS

   • or inner eye
   • temporary store for visual or spatial items
     • where the items and what it is
   • helps people navigate around and interact with the physical environment
   • Visual cache: stores visual material on form and colour
   • Inner scribe: handles spatial relationships and rehearses and transfers info in VC to CE

9. Can't do VSS and PL at the same time - seperate slave systems

   • PET scans prove this

10. EB

    • Combines info from PL and VSS and LTM together to create new ideas
      • helps you imagine elephants on skates
      • integrated info
      • holds items in wm until they are recalled
    • Evaluation
      • practical application to education
      • Lacks external validity as all experiments are lab based
