The Working Model Of Memory

Question 1

Who argued that STM is much more complex than a ‘stopping off’ point for info on its way to LTM?

Answer 1

Baddeley and Hitch

Question 2

What year did Baddeley and Hitch suggest the working model of memory?

Answer 2

1974

Question 3

What are the components of the WMM?

Answer 3

Visual-spatial scratch pad 
Central executive 
Episodic buffer
Phonological store 
Articulately loop
Primary acoustic store

Question 4

What is the central executive?

Answer 4

This system is in OVERALL CHARGE and allocates info to the other subsystems

Question 5

What memory store does working memory model explain?

Answer 5

STM

Question 6

The central executive is very flexible, how does it process info?

Answer 6

In any sensory modality (MODALITY FREE)

Question 7

The central executive can hold and manipulate info, what is its capacity?

Answer 7

LIMITED

Question 8

The Visio-spatial scratch pad holds and manipulates what kind of info?

Answer 8

VISUAL and SPATIAL info

Question 9

The Visio-spatial scratch pad relies on a VISUAL CODE, such as what?

Answer 9

Shape size and colour

Question 10

What does the VISUAL COMPONENT DEAL WITH?

Answer 10

OBJECTS and FEATURES such as shape and colour

Question 11

What form does the visual component hold info in?

Answer 11

Holds visual info from verbal stimuli I.e the appearance of letters

Question 12

What does the spatial component help with?

Answer 12

Helps us to MONITOR where we are in relation to OTHER OBJECTS as we move around our ENVIRONMENT

Question 13

What is the effect of limited capacity on the VS scratchpad?

Answer 13

It is difficult for us to perform several VS tasks at the same time

Question 14

What is the phonological store responsible for?

Answer 14

Processing SOUND based info

Question 15

What are the two sub-components of the phonological store?

Answer 15

The ARTICULATORY LOOP (the inner voice)

The PRIMARY ACOUSTIC STORE (the inner ear)

Question 16

Who conducted a study to test the capacity of the central exec?

Answer 16

Hunt

Question 17

When did Hunt conduct his study?

Answer 17

1980

Question 18

Describe the ARTICULATORY loop

Answer 18

Limited capacity VERBAL REHEARSAL LOOP used to prepare speech and to think in words as when doing mental arithmetic or memorising info

Question 19

Describe the primary acoustic store

Answer 19

Receives sound based info directly from the environment.
Relies on an ACOUSTIC CODE
Has a LIMITED CAPACITY and holds MEMORY TRACES for a few seconds before they fade

Question 20

What was the aim of Hunt’s 1980 study?

Answer 20

The investigate whether there is evidence for a LIMITED CAPACITY CENTRAL EXEC.

Question 21

What was the method of Hunt’s 1980 study?

Answer 21

P’s performed a PSYCHOMOTOR TASK - guiding a LEVER between POSTS with only their THUMB and INDEX FINGER.
At same time, completed an INTELLIGENCE TEST consisting of SPATIAL PATTERNS

Question 22

What were the results of Hunt’s 1980 study?

Answer 22

As the problems became MORE DIFFICULT, PERFORMANCE on the PSYCHOMOTOR TASK DETERIORATED

Question 23

What did Hunt conclude from his 1980 study?

Answer 23

BOTH tasks were using the same CENTRAL PROCESSOR and both were COMPETING for the same LIMITED CAPACITY
