The Working Memory Model (WMM)

Question 1

What is the wmm?

Answer 1

The WMM,baddeley and hitch,1974 is an explanation of how short term memory is organised and how it functions

Question 2

what are the components in the WMM? And how many are there?

Answer 2

4 components

central executive
Phonological loop
Visio-spatial sketchpad
Episodic buffer

Question 3

what is the central executive?

Answer 3

the central executive (CE) has a supervisory role, it monitors incoming data and divides our limited attention and allocates subsystems to tasks

Question 4

What is the phonological loop?

Answer 4

deals with auditory information

Question 5

What is the Visuo-spatial sketchpad?

Answer 5

stores visual and/or spatial information

Question 6

What is the episodic buffer?

Answer 6

it is a temporary store for information

Question 7

what is a strength of the WMM?

Answer 7

clinical evidence

support from Tim shallice and Elizabeth warringtons research on the case study of a patient KF,after a brain injury KF had poor stm ability for auditory(sound) information but could process visual information normally.

For instance his immediate recall of letters and digits was better when he read them (visual) rather than when he where to hear,when being read to him(acoustic).

KFs phonological loop was damaged but his Visiospatial sketchpad was still in tact, this strongly supports the idea of separate visiospatial and acoustic memory stores

Question 8

Limitation of the WMM?

Answer 8

it is unclear whether KF had other cognitive impairments, which may have affected his performance on memory tasks, questioning the validity of there research
