Working Memory Model

Question 1

Who designed the WMM

Answer 1

Baddeley and Hitch

Question 2

All parts of the WMM

Answer 2

Episodic Buffer
Central Executive
Visuo-spatial sketchpad
LTM
Phonological loop

Question 3

What is the Episodic Buffer

Answer 3

Temporary Store for for information

Question 4

What does the Central Executive do

Answer 4

Has a supervisory role, monitors incoming data and directs attention
- Very limited storage capacity

Question 5

What does the Visuo-Spatial Sketchpad do

Answer 5

Stores visual and spatial data
- Visual cache : Stores visual data
- Inner scribe : records arrangement of objects

Question 6

What is the Phonological Loop

Answer 6

Processes auditory information, preserves order
- Phonological store (words you hear)
- Articulatory process (allows maintenance rehearsal, keeping them in WM while needed

Question 7

Evaluation of WMM
- 2 Strengths
- 1 Limitation

Answer 7

+ Support from clinical evidence
(Shallice studied KF who had poor STM for auditory information, but could process visual info normally)
+ Dual task performance supports the VSS (Baddeley found no completion between verbal and visual task)
- Lack of clarity over Central Executive (Baddeley said it is most important but least understood - challenging integrity of model)
