The Working Memory Model

Question 1

who came up with the working memory model

Answer 1

Baddeley and Hitch

Question 2

central executive

Answer 2

coordinates the activities of the three subsystems in memory. also monitors incoming data/information

Question 3

phonological loop

Answer 3

Processes auditory information.
Is also divided into the phonological store and articulatory loop

Question 4

visuo-spatial sketchpad

Answer 4

Processes visual and spatial information
Divided into visual cache and inner scribe

Question 5

Episodic buffer

Answer 5

temporary store that brings about material from the other subsystems into a single memory rather than separate strands

Question 6

Evaluation points for the working memory model- Clinical evidence

Answer 6

STRENGTH

KF had poor auditory memory but good visual memory. Damaged Phonological Loop but Visuo Spatial Sketchpad fine

Question 7

Evaluation points for the working memory model- Dual task performance

Answer 7

STRENGTH

Difficult to do two visual tasks (or two verbal) at same time, but one visual and one verbal is OK (Baddeley et al)

Question 8

Evaluation points for the working memory model- Nature of the central executive

Answer 8

LIMITATION

Not well specified, needs to be more than ‘attention’

Question 9

Evaluation points for the working memory model- Validity

Answer 9

STRENGTH/LIMITATION

Dual-task studies support Working Memory Model but are highly controlled.
However using artificial tasks (letter sequences)
