New cards

4 components of the WMM

  • central executive

  • phonological loop

  • episodic buffer

  • visuo-spatial sketchpad


2
New cards

coding and capacity of each component

  • CE: co- senses, ca- limited

  • PL: co- auditory, ca- 2 seconds

  • EB: co- senses, ca- 3-4 chunks

  • VSS: co- visual, ca- 4 objects

what happened to KF?

  • he suffered brain damage after a motorcycle accident

  • had poor STM for verbal info (PL damaged)

  • but could process visual info normally (VSS normal)


4
New cards

what does the case study of KF suggest?

that STM isnt a single unitary store, because the PL and VSS were working as different systems

5
New cards

whats the reductionist criticism of the WMM?

it simplifies the complexity of STM into separate components

6
New cards

why is the central executive criticised?

  • it’s the least understood even though it has the most important role in directing attention, so it has been made too simple

  • it’s treated as one unit but may consist of several components
