How many main parts of the wmm are there?
|
4 or 5. it can be argued either way
|
|
What are the main parts of the wmm?
|
central executive, phonological loop, visuo-spatial sketchpad and episodic buffer
|
|
what are the two parts to the phonological loop?
|
phonological store and articulartory loop
|
|
what are the two parts of the visuo-spatial sketch pad?
|
inner scribe and visual cache
|
|
when was the episodic buffer added?
|
2000
|
|
what is the purpose of the episodic buffer?
|
to bind together all the information from the other components
|
|
what is the central executive?
|
it controls attention and coordinates the actions of the other components
|
|
What is the most important part of the wmm?
|
central executive
|
|
ture of false, the central executive has unlimited capacity?
|
false
|
|
The articulatory control system is the inner....?
|
the inner voice
|
|
the phonological store is the inner....?
|
the inner ear
|
|
What is the phonological store?
|
It hold information for about 1.5-2 seconds. Written words must be converted to spoken words
|
|
what is the articulatory control system?
|
it rehearses information verdally and has a capacity of about 2 seconds.
|
|
What is the visuo-spatical sketch pad?
|
it deals with what the information looks like and how it is laid out.
|
|
what is the visual cache?
|
passive visual store
|
|
what is the inner scribe?
|
deals with spatial relations between objects
|
|
what is the working memory model?
|
a multi-component short-term memory system
|
|
what did Braddely and Hitch (1974) think of the msm?
|
thought it was too simplistic. they thought stm was several stores and not just one. so they came up with the wmm
|
|
how do you transfer information from stm to ltm?
|
elaborative rehearsal
|
|
what did hitch and braddly do + year?
|
1974.
found that participants performed more slowly when doing 2 tasks that occupied the central execvtive than doing 2 tasks where only one involved the central executive. |
|
what does hitch and braddly's research show?
|
that doing 2 tasks that involve the same component cause difficulty as predicted by the wmm.
task 1 = central executive in phonological loop (eg true/false) task 2 = articulatory processess (repeating "the the the" - that was easy) of central exective (repeating numbers - that was hard) |
|
what did braddeley et al do + year?
|
1975.
found participants find it easier to remember short words than longer words but this disappears if participants are given an articulatory suppression task |
|
what does braddeley et al research show?
|
demontrates that existence of the articulatory process because the supperssion task means you cant rehearse the shorter words anyymore quickyl than the longer ones.
|
|
What did shallice and warrington do + year?
|
1970.
studied KF and found that in the stm, hes better remembering with viual (visuo-spatial sketch pad) than acoustic recall (phonological loop) |
|
what does shallice and warrington research show?
|
shows there are more than one component to the stm
|
|
3 weaknesses of the model!
|
wm only concerns itself with the stm.
the capacity of the central execvtive has never been measured. it isn't clear how the central executive works or what is does |
|
3 strenghts of the moel!
|
rehearsal is just 1 option within the articulatory loop instead of being the only means of tranferring information to the long-term dtore.
most psychologists preffer to ues the wmm. it is a much more plausible model than the msm because it explains stm in term of both temporary storages and active processing. |
|
evidence for the central executive!
|
bunge et al (2000)
they did a fmri (brain scan). for single and dual tasks where showed as the exact same area in the brain scan. but more activity for the dual task |
|
evidence for the phonological loop and articulatory process!
|
braddely et al (1975a)
word length effect - recall was better for short words than long ways (can rehearse more than onger ways). however, when given a articulatory suppression task ("the the the") the difference dissapeared. |
|
evidence for the visuo-spatial sketchpad!
|
braddeley et al (1975b)
light track task (trace a light), while at the same time as doing a visuo- spatial task (describing angles of the letter "F") or an articulatory task ("the the the"). doing the light track and articulatory task was the easiest. |
|
evidence for the episodic buffer!
|
braddely et at (1987)
used unrelated and related words words. remembered more related words because ltm made sense of the information, which improved the recall. |
