Working Model Of Memory

Question 1

who proposed the WMM?

Answer 1

Baddeley and Hitch

Question 2

what is the central executive?

Answer 2

• monitors incoming data
• focuses and divides our limited attention
• allocates tasks to subsystems

Question 3

what is the capacity, duration or encoding of the central executive?

Answer 3

• very limited processing capacity
• doesn’t store information

Question 4

what are the subsystems that are allocated to tasks?

Answer 4

• phonological loop
• visuo-spatial sketchpad
• episodic buffer

Question 5

what is the phonological loop?

Answer 5

• deals with auditory information
• preserves the order in which information arrives

Question 6

what is the capacity, duration or encoding of the phonological loop?

Answer 6

• coding = acoustically

Question 7

what is the phonological loop divided into?

Answer 7

• phonological store
• articulatory process

Question 8

what is the phonological store?

Answer 8

stores the words we hear

Question 9

what is the articulatory process?

Answer 9

• allows maintenance rehearsal(repeating sound or words in a loop to keep in working memory while they’re needed)

Question 10

what is the articulatory process capacity?

Answer 10

2 seconds(worth)

Question 11

what is the visuo-spatial sketchpad?

Answer 11

• stores visual and or spatial information when required
  (e.g. how many windows are in your house)

Question 12

what is the capacity, duration or encoding of the visuo-spatial sketchpad?

Answer 12

limited capacity, 3 or 4 objects

Question 13

who divided the visuo-spatial sketchpad?

Answer 13

Logie

Question 14

what is the visuo-spatial sketchpad divided into?

Answer 14

• visual cache
• inner scribe

Question 15

what is the visual cache?

Answer 15

store visual data

Question 16

what is the inner scribe?

Answer 16

record the arrangement of objects in the visual field

Question 17

what is the episodic buffer?

Answer 17

• temporary store of information
• integrating visual, spatial or verbal information processed by other stores
• maintaining a sense of time sequencing

Question 18

what is the capacity, duration or encoding of the episodic buffer?

Answer 18

limited capacity of about 4 chunks

Question 19

what does the episodic buffer link?

Answer 19

working memory to LTM and wider cognitive processes e.g. perception

Question 20

what are the evaluations of WMM?

Answer 20

+ support from case study KF, Shallice and Warrington
+ studies of dual-task performance supports separate existence of visuo-spatial sketchpad
- lack of clarity over the nature of the central executive

Question 21

what is the working model of memory?

Answer 21

explains how STM is organized and how it functions
