Q

How is the WMM and MSM different?

A

MSM is a unitary system (means a single system without any subsystems), whereas WMM is NOT a unitary store. (suggests 4 components carry out short-term memory)

Q

Brief summary of WMM process?

A
  1. Input goes to sensory memory
  2. Sensory memory to central executive (if you’ve paid attention)
  3. Central executive to LTM

- Has overall control

Q

What are the responsibilities of central executive?

A
  • Processes info from any sensory system.
  • Allocates tasks to slave systems.
  • Most important part of working model.

Q

Describe the capacity of central executive?

A
  • Limited capacity

- Has the capacity to focus, divide and switch attention.

Q

How does Braver’s study support the existence of CE?

A

Demonstrates that there is a specific area associated with the tasks carried out by CE. Suggesting there is a specific components that can be called CE.

Q

What is the phonological loop/features?

A
  • The ‘inner ear’ - deals with auditory information.
  • Holds auditory speech info.
  • Has limited capacity.
  • Consists of of phonological store + articulatory loop.

16
Q

What is the visuo-spatial sketchpad?

A
  • The inner eye
  • Limited capacity
  • Temporary memory system for holding visual and/or spatial info.
17
Q

Why was episodic buffer added to the model?

A

Added because of criticisms that the model didn’t explain LTM or how STM integrated into the LTM.

18
Q

What is episodic buffer/features?

A
  • Storage component for CE.

- Links working memory to LTM and other cognitive processes such as perception.

19
Q

What is evidence for PL?

A

Baddeley’s word length effect.

20
Q

What case supports WMM?

A

Shallice & Warrington. (KF suffered damage to brain/phonological store)

21
Q

What was the findings of Shallice and Warrington?

A
  • KF had no problem with long-term memory. These findings suggest that different parts of the brain are involved in STM and LTM.
  • MSM would disagree with this.
22
Q

What is supporting evidence for WMM?

A

Braver

Baddeley

23
Q

What are positives on WMM?

A
  • WMM supported by dual task studies.

- KF case study supports WMM

24
Q

What are limitations of WMM?

A
  • Evidence from brain-damged patients may not be as reliable.
  • Little is known about how the CE works.
  • Model doesn’t explain link between working memory and LTM
