Working Memory Model

Question 1

Who came up with WMM

Answer 1

Baddeley

Question 2

What does WMM show

Answer 2

Designed to shoe how STM is organised and how it functions

Question 3

WMM focus on when your mind is

Answer 3

Active: when you’re using STM to temporarily store or manipulate information

Question 4

5 components of WMM

Answer 4

• central executive
• episodic buffer
• visual spacing sketchpad
• articilatory process
• phonological store

Question 5

Baddeley conducted a study on

Answer 5

Dual task performance

Question 6

Def central executive

Answer 6

Monitors incoming data and gets the Slave systems to work by allocating them roles

Question 7

Def episodic buffed

Answer 7

Added in 2000 and is a temporary store which integrates all types of information linking to long term memory and processes like perception

Question 8

Def Visio-special sketchpad

Answer 8

A slave system which stores visual and stadia information when required eg if you have to visualise the number of windows on your house

Question 9

Def articulately process

Answer 9

Allows maintainance rehearsal and can hold up to 2 seconds worth of things you say

Question 10

Def phonological store

Answer 10

Stores the words you hear

Question 11

Aim of Baddeley

Answer 11

To see if there is a separate slave system that processes visual input

Question 12

Method Baddeley

Answer 12

To carry out a visual and verbal task at the same time

Question 13

Conclusions Baddeley s

Answer 13

Theur performance on each was similar to when they carried out both tasks separately but when both tasks were visual or both tasks verbal, performance on both declined

Question 14

Support Baddeley

Answer 14

Supporting working memory model because it supports the idea that there are 2 separate skate systems and they can both do different jobs at the same time

Question 15

4 evaluation points

Answer 15

Strength - supportive evidence from Baddeley
Strength - supportive evidence from patient KF
Weakness - lack of clarity
Weakness - supportive evidence has low ecological validity

Question 16

Elaboration of strength - supportive evidence from Baddeley

Answer 16

Consistency between results making them reliable

Question 17

Elaboration of strength - supportive evidence from patient KF

Answer 17

• shallice and Warrington provide support in form of case study from patient KF
• his verbal short term memory was damaged as a result of brain damage however his visual STM was still in tact
• gives support for the idea of 2 separate slave systems and suggests that only his phonological loop was damaged
• increases support for accuracy of WMM

Question 18

Elaboration weakness - lack of clarity

Answer 18

• lack of clarity over central executive
• it’s argued this part is poorly explained because doesn’t explain how the tasks are allocated to the slave systems
• the idea of the central executive is one of the key parts of the model yet its functioned isn’t fully explained causing lack of accuracy

Question 19

Elaboration weakness - supportive evidence has low ecological validity

Answer 19

• results from lab experiments researching WMM will often have low ecological value eg doesn’t relate to real life tasks
• eg repeating ‘ the the the’ isn’t representative of our everyday activists
• this can be seen in Baddeley dual task performance study

Question 20

Capacity if central executive

Answer 20

Very limited, doesn’t store information

Question 21

Capacity episodic buffer

Answer 21

Limited: 4 chunks

Question 22

Capacity visuo-social sketchpad

Answer 22

3/4 objects

Question 23

Capacity and coding phonological loop

Answer 23

2 seconds, acoustic
