Working memory model

Question 1

who came up with the working memory model?

Answer 1

Baddeley and Hitch

Question 2

What is the main part of the WMM?

Answer 2

central executive

Question 3

what are the 3 slave systems called?

Answer 3

Visuo-spatial sketch pad
episodic buffer
phonological loop

Question 4

what are the 2 inner bits of the visuo spatial sketch pad?

Answer 4

inner scribe

visual cache

Question 5

what are the 2 inner stores in the phonological loop?

Answer 5

store

articulatory process

Question 6

what does the inner scribe do?

Answer 6

forms mental image

Question 7

what does the visual cache do?

Answer 7

spatial awareness

Question 8

wat does the store within the phonological loop do?

Answer 8

holds the words you hear

Question 9

what does the articulatory process do?

Answer 9

words that are heard or seen

Question 10

what 4 things does the central executive do?

Answer 10

plan, coordinates and problem solves.

Directs attention to particular tasks and determines how resources are allocated

Question 11

what does the visuo-spatial sketch pad do?

Answer 11

Can plan a spatial task and it where visual spatial info is stored

Question 12

what does the episodic buffer do?

Answer 12

holds info that relates to visual and acoustic info

Question 13

what does the phonological loop do?

Answer 13

deals with auditory info and preserves the order of info

Question 14

what is once strength for the idea that there are 2 seperate stores?

Answer 14

PET scans

Question 15

Explain the PET scans evaluation point

Answer 15

it shows that different parts of the brain are active when using different slave systems (thus supporting their existence)
It shows that the frontal cortex is active when using the central executive and that right side of the occipital lobe is when using the VSSP

Question 16

what is one weakness to this model?

Answer 16

The CE is said to be the most important even though this is the one we know least about

Question 17

can you explain the weakness of this model

Answer 17

the CE is the one we have researched the least even though it is supposed to be the most important.
E.g a man who had trauma to the brain following the removal of a tumour, retained a high IQ but found it difficult to make decisions- both tasks involve the CE
This suggests even the CE might be multi-component, we dont know so the model in incomplete

Question 18

what is the evidence for the phonological loop?

Answer 18

Baddeley found that more short words were remembered than long words. However, when he asked participants to repeat “la la la” over and over again (known as a suppression task) he found that shorter words were no better remembered. this suggests the PL is filled with the suppression task and so doesnt have the capacity to also rehearse the words

Question 19

what is the evidence for the VSSP?

Answer 19

Baddeley gave participants a tracking task and an imagery task to complete at the same time. These could not be completed at the same time as they were both visual and requires the use of the VSSP. However, participants could complete an imagery task and a verbal task showing they use different slave systems
