Research for and against the Working Memory Model Flashcards
What research can be used to support the Central Executive’s restriction of items in conscious awareness.
Hitch and Baddeley’s Dual Research Task - the A/B study.
What findings of Hitch and Baddeley’s Dual Research Task can be used to support the Central Executive’s restriction of items in conscious awareness in the Working Memory Model?
To do visual tasks, you can only do one at a time.
To do verbal tasks, you can only do one at a time.
What case study can be used to support the WMM?
Shallice and Warrington’s case study of K.F.
How does K.F’s case study support the WMM?
Supports the need for separated stores.
What did K.F damage in his motorbike accident?
His short term memory.
What were the effects of K.F’s motorbike accident on his ability to function?
He could understand and communicate in ways such as drawing or writing but cannot speak.
What did the effects of K.F’s motorbike accident mean for the WMM?
It is correct to separate the stores in the way that the WMM does.
What can be used to both support and criticise the WMM?
Paulesu’s PET scans.
What did Paulesu’s PET scan find evidence of?
The VSS and PL.
What did Paulesu’s PET scans fail to find evidence of?
The CE.
What can you not get in a brain scan?
Demand characteristics.
What was the verbal task the ppts were asked to do in Paulesu’s PET scans, why was this task chosen?
They counted to 20 because so much rehearsal and no visual is used.
What was the visual task the ppts were asked to do in Paulesu’s PET scans, why was this task chosen?
Shown a moving pattern, no speech in head so no verbal.
How did Paulesu’s PET scans find no evidence of the central executive?
Different areas lit up when the ppts were asked to o the verbal task compared to the visual task, yet no other area lit up.
The CE wither exists separately in the different sections or not at all.
Is Paulesu’s PET scans reliable, how come?
Yes very, loads of ppts because they can be fully informed and brain scans are very ethical.
