MEMORY: The Working Model of Memory Flashcards
Who made the WMM
Baddeley and Hitch
What is WMM
Explanation of how STM organised and how it functions
wmm concerned with …
mental space and how its active when we are temporarily storing and manipulating info
e.g understanding another language
Name the 4 components of teh WMM
central executive
phonological loop
visuo spatial sketchpad
episodic Buffer
Central executive has what type of role
supervisory role
what 3 things does CE do
monitor incoming data
focuses and divides our limited attention
allocates subsystems to tasks
Describe processing capacity of CE
limited processing capacity
How does CE store info
TRICK QUESTION HAHA cause it doesn’t store info
What does the phonological loop deal with and therefore what type of coding
auditory info so coding is acoustic
What does the phonological loop preserve
the order which infor arrives
What is the phonological loop subdivided into
phonological store
articulatory process
What does the phonological store store
store the words you hear
What does the articulatory process allow
maintainenance rehersal - repeating words in a loop to keep em in wm whilst needed
What is the capacity of the articulatory process
two seconds worth of what you can say
What do vss do
store visual and/or spatial information when required
give an example of when you’d use vss
working how many windows there are on your house as you visualise it
Describe the capcity of the vss
limited
according to Baddeley the capacity of the VSS is what #wise
3/4 objects
robert logie divided the VSS into
visual cache
inner scribe
What does the visual cache do
stores visual data
What does the inner scribe do
records arrangment of objects in teh visual field
When was the Episodic Buffer made
2000
What is the EB
Temporary store of information
integrating the visual, spatial and verbal info processed by other stores
and recordng events that are happenin
what are the 2 functino of EB
integrating
recording
what does the eb integrate
visual. spatial and verbal info processed by other stores
The EB can be seen as
storage component of the CE
what does the EB record
events (episodes) that are occuring
What is the capacity of the EB
limted capacity about 4 chunks
What does the episodic buffer link
working memory to LTM and wider cognitive processes e.g perception
evals for WMM
STRENGTH clinaical evidence from case study of patient KF
COUNTERPOINT unclear if he had other cognitive impairments
strenght - dual task performance
limitation - nature of the central executive
exaplin support form KF study
after x injury KF had poor x ability for x info
but could process x info as per x
e.g immediate recall of digits/letters better when x read them (visual) than when others read them (x)
showing his x x damaged but x intact
therefore KF findingsd strongly x x of seperate x and x memory stores
after brain injury KF had poor STM ability for sound info
but could process visual info as per
e.g immediate recall of digits/letters better wjem je read them (visual) than when others read them (Acoustic)
showinghis phonological loop damaged but VSS intact
therefore KF findingsd strongly suggest existence of seperate visual and acoustic memory stores
counterpoint to : support from KF study
unclear whether KF had other cognititve impairments (apart from damage to phonological loop) which may have affected his performance on memory tasks
injury cuased by motorcycle
trauma may have affected his cognitive performance quite apart from any brain injury
this challenges evidene that comes from clinical studies of people with brain injuries that may have affected many diff systems
Explain lack of clarity over nature of CE
Baddeley x recognised when he said xx most important but x understood component of WMM
Showing CE needs to be mroe clearly x than just simply being x
e.g some psychologists believe CE may x of seperate x
x/unclear evidence shows the CE is an x component and this challenges the x of the WMM
Baddeley himself recognised when he said CE most important but least understood component of WMM
Showing CE needs to be mroe clearly specified than just simply being attention
e.g some psychologists believe CE may consist of seperate subcomponents
conflicitng/unclear evidence shows the CE is an unsatisfactory component and this challenges the integrity of the WMM
strenght dual task studies
studies of x task performance support the seperate existence of x
when baddley et als pt carried out a x and x task at the same time
perfomrnace on eahc was x to when they did tasks x
but when x tasks visual/verbal, performance declined x
this is cause both x tasks compete for teh same x(vss)
but no x when performing a
x and verbal task together
showing ther x be a x subsystem(x) that processes the visual x and one for verbal processing (pl)
studies of dual task performance support the seperate existence of VSS
when baddley et als pt carried out a visual and verbak task at the same time
perfomrnace on eahc was similar to when they carried out tasks seperatley
but when both tasks visual/verbal performance declined substantially
as both visual tasks compete for teh same subsystem(vss)
but no comp when performing a visual and verbal task together
showing ther must be a seperate subsystem(vss) that processes the visual input and one for verbal processing (pl)
