Q

What does the central executive do?

A

Monitors incoming data, focuses and divides our limited attention and allocates ‘slave systems’ to tasks.

Q

One strength is that there is clinical evidence from studies. - Explain this point

A
  • Case study: KF.
  • KF had poor STM ability for sound information but could process visual information.
  • Suggests his phonological loop was damaged but his VSS was intact.
  • Supports existence of seperate visual/acoustic memory stores.

Q

One strength is that there are studies of dual-task performance that support the seperate existence of the VSS. - Explain

A
  • Baddeley’s participans carried out verbal and visual task at the same time, performance was similar to when they did them seperate.
  • But when both were visual or both were verbal, performance decreased.
  • Both tasks used same slave system.
  • Suggests there must be a seperate slave system to process visual input.

Q

One limitation is that there is a lack of clarity over the nature of the central executive. - Explain

A
  • Baddeley: ‘The CE is the most important but least understood component’.
  • Needs to be more specified than just being ‘attention’.
  • CE is an unsatisfactory component and this challenges the integrity of the WMM.
