the working memory model
- proposed by Baddeley
and hitch 1974, the working
memory model
CHALLANGES and
DISPUTES atkinson ad
shiffrin claim that stm is
a unitary store
- it proposes that the
memory is an alliance
of several memory
systems working
together
- this model is a
development of the
multi store model and it
puts forward a system
involving active
processing and shirt
term storage
information
- it proposes that the
memory is an alliance
of several memory
systems working
together
- the key components
- the central executive
- this is the key
component of
working memory.
the function of
the central
executive is to
direct attention to
particular tasks
determining at ay
time how the
three slave
systems are
allocated tasks
- this is the key
component of
working memory.

- the phonological loop
- this deals with auditory
information ad preserves the
order of information. the loop
consists of the phonological sore
and the articulatory control/loop
- the phonological
store holds the
words you hear
like an inner ear,
this stores
sound without
meaning and for
a short period of
time. the items
are acoustically
coded.
- the articulatory control/loop
is used for word that are
heard or seem and these
words are silently repeated
(looped) like an inner voice.
this is a form of maintenece
rehearsal, it hold verbal
information in auditory code,
it silently repeats words that
are heard or seen, eg trying
to remeber a phone number
in your head.

- the visuo spatial sketchpad
- this stores and manipulates
visual and spatial information. it
deals with this kind of information
and is involved in pattern
recognition and perception of
movement. it deals with what
items look like and the physical
relationsip between them,

- the episodic buffer
- this is an extra storage system that
has a limited capacity, just like the
other components, the episodic buffer
integrates/ brings together information
from the central executive, phonological
loop, visuo spatial sketchpad amd also
long term memory.

- the central executive
- key study on the working memory; BADDELY AND HITCH (1974)
- AIM; to investiate whether participants can use
different arts of working memory at the same time,
the dual task tecnique was used.
- METHOD; participants were given two tasks to do simultaneously (at the same
time) task 1; they were given a task that occupied the visuo spatial sketchpad
(eg.drawing a cat) and articulatory loop (reapeating word the) and TASK 2; they
were give a task that involved both the aticulatory loop and articulatory oop
- RESULTS; task 2 was completed more slowly by
participants when they were given a task involving
the same component (articulatory loop) task 1 was
completed much quicker when given tasks that
involved different compnents.
- CONCLUSION; the study suggests that doing two tasks hat involve the same
component/slave system causes difficultly. it also suggest that when different
components/slave systems are used the performance is not affected.
- evauation; as its a lab experiment it has high levels of control and can therefore establish cause and effect. so we can
be confident that the iv (type of task given to participant) directly effected the dv (length of time it took to answer
questions
- however a weakness is that it has low ecological validity and therefore it results dont test memory in a meaningful/ realistic way.
