working memory model

Question 1

what is the WMM?

Answer 1

an explanation of how STM is organised and how it functions

Question 2

what components are in the WMM?

Answer 2

• visuo-spatial sketchpad (vss)
• central executive
• episodic bugffer
• long term emery
• phonological loop (articulacy control system and phonological store)

Question 3

what is the central executive (CE)

Answer 3

• attentional process that monitors incoming data
• allocates slave systems to tasks
• very limited storage capacity

Question 4

what is the phonological loop?

Answer 4

• consists of phonological store and articulatory control system
  deals with auditory info and preserves the order info arrives in
• phonological stores words
• articulatory allows maintenance rehearsal (Repeating sounds to remember)

Question 5

what is the visuo-spatial sketchpad (VSS)?

Answer 5

• stores usual or spatial info when required

- logie (95) divided it into visual cache (visual data) and inner scribe ((arrangement of objects in visual field)

Question 6

what is the episodic buffer (EB)?

Answer 6

• added in 2000
• temporary store for information
• integrates visual, spatial and verbal info into other stores
• maintains sense of time sequencing (episodes) - links to LTM

Question 7

+ clinical evidence/ case studies

Answer 7

• shalice and Warrington (70) studied patient KF with damage to hippocampus
• STM verbal ability was poor but visual fine, showing damage to only phonological loop (separate stores)

Question 8

+ Dual task performance

Answer 8

Baddeley (75) show it was more difficult to do 2 visual tasks than a visual and verbal task at the same time
- both actions aren’t coming from same slave system
(support operate function of VSS)

Question 9

• lack of clarity over central executive

Answer 9

• the comps ent doest explain anything
• Baddeley (03) said its important but not understood (some believe it has separate components)
• WMM not fully explained
