Who developed the working memory model?
Baddeley
and
Hitch
What part of memory is the WMM an explanation for?
Short-term
memory
What is the WMM concerned with?
The
'mental space'
active when we are
temporarily
storing
and
manipulating
information
What are the five main components of the WMM?
Central executive
,
phonological loop
,
visuo-spatial sketchpad
,
episodic buffer
,
long-term memory
What role does the central executive have?
A
'supervisory'
role
Does the central executive store information?
No
What is the processing capacity of the central executive?
Very
limited
What does the central executive do?
Monitors
incoming data
,
focuses
and
divides
our
limited
attention
and allocates
subsystems
to
tasks
What two components is the phonological loop split into?
1 .
Phonological store
2 .
Articulatory process
What is the phonological store?
Stores
words
we
hear
What is the articulatory store?
Repeats
sounds
/
words
in a
loop
to keep them in
working memory
while
needed
(allows
maintenance rehearsal
)
What is the capacity of the phonological loop believed to be?
2
seconds worth of
what you can say
What does the phonological loop do?
Deals with
auditory
information and
preserves
the
order
in which
information
arrives
What does the visuo-spatial sketchpad
do
?
Stores
visual
and/or
spatial
information
when
required
What two components is the visuo-spatial sketchpad divided into according to Logie?
1 .
Visual cache
2.
Inner scribe
Who split the visuo-spatial sketchpad into two components?
Logie
What is the capacity of the visuo-spatial sketchpad according to Baddeley?
3
or
4
objects
What is the visual cache?
Stores visual data
What is the inner scribe?
Records
the
arrangement
of
objects
in the
visual field
What is the episodic buffer?
A temporary store for
information
, integrating the visual, spatial and
verbal
information processed by stores
What does the episodic buffer link working memory to?
Long-term
memory
What can the episodic buffer be seen as?
The
storage
component of the
central executive
What is the capacity of the episodic buffer?
About
4
chunks
What does the episodic buffer maintain a sense of?
Time sequencing
-
recording
episodes
that are
happening
What can the working memory model explain that the multi-store model cannot?
Dual-task performance
