WMM

Question 1

What is maintenance rehearsal?

1

Answer 1

• Repeating sounds/words in a loop to keep in PL store when needed

Question 2

What is the capacity of VSSP?

1

Answer 2

• Limited capacity, 3 or 4 objects

Question 3

What is the capacity of the episodic buffer?

1

Answer 3

• Limited capacity, 4 chunks

Question 4

Evaluate WMM

3

Answer 4

Dual task performance studies support predictions of WMM. Baddley found when ppt performed visual/verbal task together, performance no worse than carried out separate. 2 visual tasks = performance both declined. Separate slave subsystems

CE is an unsatisfactory component. Baddley recognised this when wrote ‘CE is most important but least understood’. Needs to be more clearly specified than j attention. WMM has not been fully explained

Understand nature of Amnesia. KF experienced amnesia after brain surgery, had poor STM for auditory info but could process visual info normally. PL damaged but VSSP was intact. Amnesia isn’t a ‘global’ disorder that affects all memory functioning

Question 5

What is the role of the central executive?

1

Answer 5

• Attentional process (focuses, divides and switches our limited attention). Very limited processing capacity

Question 6

What is the role of the phonological loop and what is it divided into?
2

Answer 6

• Deals w auditory info i.e. sounds (acoustic encoding)

- Subdivided into PL store (stores auditory info) and articulatory process (allows maintenance rehearsal)

Question 7

What is the role of VSSP and what is it subdivided into?

2

Answer 7

• Temporarily store visual/spatial info when required

- Subdivided into visual cache (stores visual data) and inner scribe (allows rehearse visual and spatial info)

Question 8

What is the role of the episodic buffer?

1

Answer 8

• Temporary store that integrates the acoustic, visual and spatial info processed by other slave systems
