Q

What does the WMM show about the STM which is different to the MSM?

Q

Why was the episodic buffer added to the WMM?

A

They had faced criticisms for not including the LTM so they added it as a way of explaining the link between STM and LTM

Q

What were the creators of the WMM never interested in explaining which explains why they didn’t add the episodic buffer?

A

They were never interested in explaining how information is transferred from the STM to the LTM

Q

If your working memory is using multiple subsystems from the same component, what will happen to processing?

16
Q

Why will processing slow down if the working memory is using a different subsystem of the same component?

A

Because each thing you’re trying to do is competing for the same resources (due to limited capacity)

Q

Procedure of Baddeley’s Dual Task experiment

A

Participants asked to repeatedly say ‘la’ when reading a particular extract. After this they were asked to tell the researcher what they had just read

23
Q

Role of the CE

A

Process information and then send it to one of the 2 subsystems

24
Q

Capacity of CE

A

Limited capacity

25
Q

Result of a damaged CE

A

Might mean that new STMs cannot be processed

26
Q

What does the CE allow us to switch attention between?

A

Switch attention between tasks

27
Q

VSS

A

Visuospatial sketchpad

28
Q

Another name for the VSS

A

The inner eye

29
Q

Capacity of the VSS

A

Limited capacity

30
Q

What information does the VSS deal with?

A

Visual information

31
Q

Examples of visual information

A

An image of something
Spatial awareness
Planning a route

32
Q

What type of system is the VSS?

A

A subsystem

33
Q

PL

A

Phonological loop

34
Q

What is the PL made up of?

A

The inner voice and inner ear

35
Q

What type of system is the PL?

A

A subsystem

36
Q

What type of information enters the inner ear?

A

Speech-based information

37
Q

Where does information enter the inner ear via?

A

The CE

38
Q

How does information enter the inner ear?

A

By sub-vocal repetition

39
Q

Where does sub-vocal repetition of information take place?

A

In the inner ear

40
Q

What type of information is reading information?

A

Speech-based information - NOT VISUAL INFORMATION

41
Q

Duration of information in the PL

A

Up to 2 seconds

42
Q

What process allows information to enter the LTM?

A

Sub-vocal repetition

43
Q

Which case study supports the WMM?

A

The KF case study

44
Q

What did KF suffer from?

A

A brain injury as a result of a motorcycle accident

45
Q

What did KF not have problems with as a result of his brain injury?

A

His LTM

46
Q

Who carried out the KF case study?

A

Warrington and Shallice

47
Q

What was KFs ST forgetting of auditory letters and digits (things that he heard) much greater than?

A

His forgetting of visual stimuli (things that he saw)

48
Q

What was KFs STM deficit limited to?

A

Verbal materials

49
Q

What could KF remember and what couldn’t KF remember?

A

Could remember meaningful sounds but couldn’t remember words

50
Q

What about the KF case study showed that there are separate STM components for the VSS and PL?

A

The fact that his memory of visual information was largely unaffected

51
Q

Positive evaluation for WMM: dual task experiment

A

It was conducted in a lab (highly controlled conditions) meaning extraneous variables could be controlled to establish a cause-and-effect relationship

52
Q

Positive evaluation for WMM: KF

A

Only some aspects of his STM were damaged which supports WMM as KF showed STM has different components

53
Q

Positive evaluation for WMM: detail

A

WMM more detailed than MSM

54
Q

Negative evaluation of WMM: trivial tasks

A

In dual task experiment participants asked to repeatedly say ‘la’ when reading an extract. This experiment is not something people do on everyday life so therefore the validity of the findings is decreased

55
Q

Negative evaluation of WMM: dual task experiment conducted in lab

A

Means research may lack ecological validity

56
Q

Negative evaluation of WMM: vagueness of WMM

A

Vague about central executive and relationship of STM with LTM
