Memory: MSM, WMM and types of LTM

Question 1

Name the slave systems of the WMM (working memory model)

Answer 1

Phonological loop and visuo-spatial sketchpad

Question 2

Name the components of the slave systems of the WMM

Answer 2

Phonological loop- phonological store and articulatory control system
Visuo-spatial sketchpad- Inner scribe and Visual Cache

Question 3

What do the components of the slave systems of the WMM do?

Answer 3

Phonological store- stores sounds for a few seconds e.g cat meow
Articulatory store- subvocal repetition for maintenance rehearsal
Inner scribe- spatial awareness of object distance
Visual Cache- visual inputs e.g colours

Question 4

What does the central executive do?

Answer 4

Controls attention and directs information to the slave systems.

Question 5

What the episodic buffer do?

Answer 5

General storage for other sensory inputs and sends info to the LTM

Question 6

Who was the working memory model proposed by?

Answer 6

Baddeley and Hitch

Question 7

Evidence for the WMM?

Answer 7

Baddeley and Hitch: Dual tasks studies
found performance was impaired when asked to do two tasks involving the same slave system, and performance improved when the tasks involved different slave systems
-Shows that there are multiple stores and that attention is limited

Question 8

Evaluation of WMM?

Answer 8

-Central executive and episodic buffer are vague and are difficult to test empirically- suggests problems with internal validity
-Demonstrates separate STM stores where the MSM could not
-Does not discuss the LTM as having separate stores
-Of the cognitive approach

Question 9

Name the types of LTM

Answer 9

Episodic
Semantic
Procedural

Question 10

Evaluation of evidence of WMM?

Answer 10

-Baddeley and Hitch- lab study- lacks eco validity (tasks would not occur in real life) though it does hold construct validity
