Working Model Of Memory-BADDLEY + HITCH

Question 1

Explain the intro of the working store model of memory.

Answer 1

-explains how the STM works
-the STM is not a unitary store
-they are connected stores which work independently as active processors

Question 2

What are the 3 parts of the STM including the ‘boss’

Answer 2

-central executive
-phonological loop
-visual-spacial sketchpad
-episodic buffer

Question 3

How does the central executer works?

Answer 3

-attentional process
-monitors incoming data
-decides what’s done
-delegates tasks accordingly
-takes on the most demanding tasks

Question 4

How does the phonological loop work?

Answer 4

-auditory information passes from the CE
-phonological store, inner ear
-articicularly loop, silently repeating and rehearsing(maintenance rehearsal)
-codes acoustically

Question 5

How does the visual-spacial sketchpad work?

Answer 5

-visual information passes from the CE
-responsible for setting up images
-temporarily stores visual and spacial information
-capacity is 3-4 items and codes visually

Question 6

Briefly explain the episodic buffer.

Answer 6

Collects and combines information from the other parts and creates a event (episode)

Question 7

What are the 3 evaluations including a discussion for the working memory model?

Answer 7

-Shallice and Warrington
-DISCUSSION:low population validity
-Dual Tasks

Question 8

Explain the Evaluation of Dual Tasks?

Answer 8

-supports the notion that there are separate components in the STM which have limited capacity
-For Example Baddley found that ppt found it more difficult to perform two visual tasks at the same time
-(use a pointer to track light on a screen while imagining the letter ‘f’)
-than performing the visual task alone or with a verbal task
-(silently repeating the word ‘the’)
-because it suggests that doing 2 visual tasks is competing for capacity of the same slave system
-Whereas when doing a visual and verbal task the is no decrease in performance as there is no competition for capacity
-increases credibility

Question 9

Explain the evaluation for Shallice and Warrington?

Answer 9

-In the 1970 Shallice and Warrington studied the patient KF who suffered from amnesia
-KF’s recall for digits was poor when read out loud
-recall was better when he could visually see the digits himself
-Supports because it suggests that there must be different stores within the STM
-one to process visual information and one to process auditory information,as the Pl is damaged
