22
Q

What do studies of dual-task performance show in relation to the working memory model?

A

There must be a separate slave system that processes visual input, and one for verbal processing (the VSS and the PL)

Q

When Baddeley asked participants to carry out a visual and verbal task at the same time (dual task), what did he find?

A

Their performance on each was similar to when they carried out the tasks separately

24
Q

Baddeley found that when people performed a visual and verbal task at the same time, their performance on each was similar to when they carried out the tasks separately. What can we conclude from this?

A

There is no competition when performing a verbal and visual task together

25
When Baddeley asked participants to carry out two verbal or two visual tasks at the same time, what were his findings?
Performance on both declined substantially
26
When Baddeley asked participants to carry out two verbal or two visual tasks at the same time, why did performance decline substantially?
Because both visual tasks compete for the same slave subsystem
27
What type of information does the phonological loop deal with, as proposed by the working memory model?
Auditory information
28
Coding in the phonological loop is...
acoustic
29
True/False: The phonological loop doesn't preserve the order in which information arrives
False: It does
30
True/False: The phonological loop is subdivided
True
31
According to the working memory model, what is the phonological loop subdivided into?
The phonological store and articulatory process
32
What is stored in the phonological store according to the working memory model?
Words you hear
33
Which part of the working memory model allows for maintenance rehearsal?
Articulatory process in the phonological loop
34
Maintenance rehearsal
Repeating things in a loop to keep them in working memory while they are needed
35
What is the capacity of the articulatory process believed to be?
Two seconds worth of what you say
36
When was the episodic buffer added to the working memory model?
2000
37
According to the working memory model, the episodic buffer is a temporary/permanent store of information
Temporary
38
What is the role of the episodic buffer in the working memory model?
Integrating the visual, spatial and verbal information processed by other stores to maintain a sense of time sequencing
39
Which part of the working memory model is responsible for maintaining a sense of time sequencing?
The episodic buffer
40
Which part of the working memory model can be seen as the storage component of the central executive?
The episodic buffer
41
What does the episodic buffer record?
Events (episodes) that are happening
42
The episodic buffer links working memory with...
long-term memory and wider cognitive processes such as perception
43
What is the main criticism of the central executive in the working memory model?
There is lack of clarity over the nature of the central executive
44
The central executive has been criticised as it needs to be more clearly specified than just simply...
'attention'
45
True/False: Some psychologists believe the CE may consist of subcomponents
True
46
Why does the central executive challenge the integrity of the WMM?
It is an unsatisfactory component
47
KF had a brain injury that made him have poor STM ability for auditory information, and/but...
but could process visual information normally
48
KF's immediate recall of letters and digits was better when...
he read them (visual)
49
KF's immediate recall of letters and digits was worse when...
they were read to him (acoustic)
50
KF's phonological loop was _______ but his visuo-spatial sketchpad was...
damaged, intact
51
The fact that KF's phonological loop was damaged but his visuo-spatial sketchpad was intact strongly supports the existence of...
separate visual and acoustic memory stores
52
What is the main criticism of the case of KF?
It is unclear whether he had other cognitive impairments which might have affected his performance on memory tasks, other than the damage to his phonological loop
53
Why does the fact that KF's injury was caused by a motorcycle accident potentially weaken the validity of the findings of his case study?
The trauma involved may have affected his cognitive performance quite apart from any brain injury
54
Baddeley said the central executive was the most...
important but least understood component of working memory
55
What did Baddeley say the capacity of the episodic buffer was?
About four chunks
