Q

wmm concerned with …

A

mental space and how its active when we are temporarily storing and manipulating info

e.g understanding another language

16
Q

give an example of when you’d use vss

A

working how many windows there are on your house as you visualise it

17
Q

Describe the capcity of the vss

18
Q

according to Baddeley the capacity of the VSS is what #wise

A

3/4 objects

19
Q

robert logie divided the VSS into

A

visual cache
inner scribe

20
Q

What does the visual cache do

A

stores visual data

21
Q

What does the inner scribe do

A

records arrangment of objects in teh visual field

22
Q

When was the Episodic Buffer made

23
Q

What is the EB

A

Temporary store of information

integrating the visual, spatial and verbal info processed by other stores

and recordng events that are happenin

24
Q

what are the 2 functino of EB

A

integrating
recording

25
what does the eb integrate
visual. spatial and verbal info processed by other stores
26
The EB can be seen as
storage component of the CE
27
what does the EB record
events (episodes) that are occuring
28
What is the capacity of the EB
limted capacity about 4 chunks
29
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
31
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
32
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
33
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
34
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)
