The Working Memory Model

Question 1

Who developed the working memory model

Answer 1

Baddley and hitch

Question 2

What is the working memory model

Answer 2

A model for how stm is stored and its functions

Question 3

What are the 4 components of the wmm

Answer 3

Central executive
Phonological loop
Visio spatial sketchpad
Episodic buffer

Question 4

What is the central executive

Answer 4

Supervisory role
Monitors data and divides attention
Limited processing capacity
Doesn’t store info

Question 5

What is the phonological loop

Answer 5

Deals with auditory information
Subdivisions - phonological stores what you hear
And articulatory process allows maintenance rehearsal

Question 6

What is the Visio spatial sketchpad (includes visual cache and inner scribe)

Answer 6

Stores visual and spatial information
Capacity of 3/4 objects
Visual cache - stores visual data
Inner scribe - arrangement of objects in the visual field

Question 7

What is the episodic buffer

Answer 7

Temporary storage information for CE
Intergrates visual spatial sketchpad and verbal info
Capacity of 4 chunks
Links working memory to long term memory

Question 8

What are the 2 strengths of the WMM

Answer 8

Clinical evidence - KF study (poor stm for auditory info but good for visual Info , however may have had other brain issues)

Dual task performance - studies of dual tasks show when doing a visual and verbal task they can but can’t do 2 visual tasks and fights for the same store

Question 9

What is a limitation if the WMM

Answer 9

Lack of clarity over the nature of the CE
Baddley stresses importance of it whereas it’s not specified enough so lacks integrity
