The Working Memory Model

Question 1

The working memory model

Answer 1

A representation of short term memory, suggesting that the STM is a dynamic processor of different types of information using subunits co-ordinated by a central decision-making system

Question 2

Central executive

Answer 2

The component of the WMM that co-ordinates the activities of the three subsystems in the memory. It allocated processing resources to those activities

Question 3

Phonological loop

Answer 3

The component of the WMM that processes information in terms of sound. This includes written and spoken material. It is divided into the phonological store and the articulary process

Question 4

Visio-spatial sketchpad

Answer 4

The component of the WMM that processes visual and spatial information in a mental space often called the inner eye

Question 5

The episodic buffer

Answer 5

The component of the WMM that brinds together material from the other subsystems into a single memory rather than seperate strands. It also provides a bridge between working memory and long-term meory

Question 6

Central executive capacity and storing

Answer 6

Very limited capacity and doesnt store information

Question 7

What is the coding in the phonological loop?

Answer 7

Acoustic

Question 8

What is the PL divided into?

Answer 8

The phonological store, and the articulatory process

Question 9

The phonological store

Answer 9

Stores words we hear

Question 10

The articulatory process

Answer 10

Allows the mainteneace rehearsal

Question 11

What is the capacity o the articulatory process?

Answer 11

Two seconfd worth of words

Question 12

Visual casge

Answer 12

Stored visual data

Question 13

Inner scribe

Answer 13

Records the arrangement of objects in the visual field

Question 14

Who added the episodic buffer to the WMM?

Answer 14

Baddeley in 2000

Question 15

What is the capacity of the episodic buffer?

Answer 15

Four chunks

Question 16

KF case study

Answer 16

After his brain injury, KF’s STM had low ability for auditory information but he could process visual information normally. His phonoliogical loop was damaged but his visio-spatial sketchpad was intact

Question 17

What did the KF findings support?

Answer 17

Seperate visual and acoustic memory stores

Question 18

What are the limitations of the KF study?

Answer 18

It is uncleaer wether KF had other cognitive impairment wich might have affected his performance on the memory tasks

Question 19

Baddeley’s dual-task study 1975

Answer 19

Participants carried out a visual and verbal task at the time. Their performance was similar when they did the tasks separately. However, when the tasks were both visual or both verbal tasks use the same slave subsystem, and when there is one of each task, they are using a different slave subsystem

Question 20

What did Baddeley’s dual-task study show?

Answer 20

There must be seperate slave systems that process visual input and verbal input

Question 21

What are the limitations of the dual-task study?

Answer 21

The Study tasks lacked mundane realism

Question 22

Who developed the WMM

Answer 22

Baddeley and hitch

Question 23

What process does the central executive use?

Answer 23

Focusing and dividing and switching information
