Working Memory Model

Question 1

What is the working memory model

Answer 1

It is a representation of STM. It suggests that STM is a dynamic processor of different types of information using sub-units coordinated by a central decision-making system.

Question 2

What is the Central Executive

Answer 2

It is the component of the WMM that coordinates the activities of the three subsystems in memory. It also allocates processing resources to those activities

Question 3

What is the phonological loop

Answer 3

It is the component of the WMM that processes information in terms of sound. This includes both written and spoken material. It’s divided in the phonological store and articulatory process.

Question 4

What is the visuo spatial sketchpad

Answer 4

It is the component of the WMM that processes visual and spatial information in mental space often called our inner eye.

Question 5

What is the episodic buffer

Answer 5

It is the component of the WMM that brings together material from the other subsystems into a single memory rather than separate strands. It also provides a bridge between WM and LTM

Question 6

What are assumptions abou the approach of the WMM

Answer 6

Baddeley and Hitch suggest a more complex and dynamic STM than the MSMs version.
● It has several but connected parts, unlike the single STM store of the MSM.
● It is an active system. It allows us to work things through, like mental arithmetic, but has a limited capacity.
● The model consists of four main components: Each of which are qualitatively different - especially in terms of capacity and coding.

Question 7

Who were the psychologists that developed the WMM

Answer 7

Baddeley and Hitch

Question 8

What is the central executive known as

Answer 8

The BOSS od rhe working memory model as it controls the whole system

Question 9

What does the central executive control

Answer 9

Attention and directs information to the two slave systems

Question 10

What is the capacity of CE

Answer 10

Very limited

Question 11

What does PL deal with

Answer 11

Auditory info and preserved info order

Question 12

What are the 2 parts of PL

Answer 12

Phonological store and articulatory process

Question 13

What is the phonological store

Answer 13

Stores acoustic items for a short period of time

Question 14

What is the articulatory process

Answer 14

It allows maintenance rehearsal, repeating words to keep them jn the WM

Question 15

What is the capacity of PL

Answer 15

2 seconds worth of what u say

Question 16

What does the visuo spatial sketchpad deals with

Answer 16

Visual and spatial tasks

Question 17

What are the 2 subcomponents of VSS

Answer 17

Inner scribe and visual cache

Question 18

What is the inner scribe

Answer 18

It deals with the spatial relationship between objects

Question 19

What is the visual cache

Answer 19

It stores visual information

Question 20

When was the episodic buffer added to the model

Answer 20

In 2000

Question 21

What does the EB do

Answer 21

Binds all the information together and sends it to the LTM

Question 22

Why did Baddeley add the EB

Answer 22

Because he realised that the model had no general storage facility

Question 23

What was the theory behind the WMM

Answer 23

Dual task performance, it illustrates tgat there is no interference when 2 tasks are being performed together

Question 24

What was observed with with the dual task performance

Answer 24

If both were visual, each task was reformed slower compared to if one was visual and one was auditory

Question 25

What are the strengths if WMM

Answer 25

.patient study on KF supported the existence of separate visual and acoustic stores
.dual task performance provides evidence for visuospatial sketchpad

Question 26

What is a limitation of WMM

Answer 26

.lack of clarity
.cog psychologists don’t think this model really explains anything
.evidence from brain damaged patie to to always reliable as ut is a unique case
