Working memory model

Question 1

What is the working memory model

Answer 1

Describes the function of STM

Question 2

What is the central executive

Answer 2

Controls the other systems, involved in dual processing, an attention process with limited capacity.

Question 3

What is the phonological loop

Answer 3

• Involved with speech
• acoustic coding and speech based
• limited capacity
• contains the articulatory control system which is a rehearsal loop and the phonological store which is where information is stored in acoustic form.

Question 4

What is the visuo-spacial sketchpad

Answer 4

Stores memory for what things look like and where they are in relation to each other. Visual coding.

Question 5

What is the episodic buffer

Answer 5

Coordinates the two stores into one thought. a buffer between working memory and LTM.

Question 6

What is dual processing

Answer 6

It is possible to carry out visual and phonological tasks simultaneously

• CE controls dual processing
• Only possible if the overall demand isn’t too great
• If either task is too demanding the performance will be compromised.

Question 7

Strengths to the WMM

Answer 7

+Strong empirical support for separation of VS and PL tasks. (Baddley)
+supported by brain studies (VS and PL tasks use different parts of the brain)
+CE is supported by KF

Question 8

Weakness to the WMM

Answer 8

The CE is less understood than the other components and less researched.

Question 9

empirical support for destinction

Answer 9

Baddely- couldn’t perform task in same modality

Question 10

Brain studies

Answer 10

Baddely- different areas.

Question 11

Patient KF

Answer 11

Motorcycle accident- could do visual but not sound
