Working memory model

Question 1

What are the components of WMM

Answer 1

Central executive 
Episodic buffer
Visuo-spatial sketchpad 
Articulatory control system 
Phonological loop
Long term memory

Question 2

Who created the WMM and what is it

Answer 2

Baddeley and Hitch . An explanation of how STM is organised and how it functions
For eg WMM is concerned with the part of the mind that is active when working in an arithmetic problem

Question 3

Describe Central executive

Answer 3

an attentional process which monitors incoming data
and allocates slave systems to tasks

CE : coding flexible and limited capacity

Question 4

Describe Phonological loop and what it subdivided into

Answer 4

processes auditory information arrives then subdivided to:

• phonological store: stores the words you hear
• articulatory process : allows maintenance rehearsal

Question 5

Describe Visuo-spatial sketchpad and what it is sub-divided into

Answer 5

stores visual/spatial information when required
Logie 1995 subdivided into:
visual cache : stores visual data
inner scribe : records arrangement of objects in visual field

Question 6

episodic buffer (4)

Answer 6

• added in 2000
  -temporary store for information
  -integrates visual, spatial and verbal information from other stores
  -maintains sense of time sequencing (records events that are happening)
  links to LTM

Question 7

Name the coding and capacity for each store

Answer 7

PL: co is acoustic, cap is 2 seconds of what you can say
VSS: co is visual spatial ;cap is 3-4 objects
EB: co is flexible ; cap is 4 chunks

Question 8

Name 3 strengths of WMM

Answer 8

• case of KF supports separate STM stores
• word length effect supports the phonological loop
• dual task performance studies support the VSS

Question 9

Name 1 limitations of WMM

Answer 9

-lack of clarity over the central executive
