Models Of Memory

Question 1

What is the multi-store model (MSM) ?

Answer 1

• Atkinson & Shiffrin
• describes flow between 3 storage systems of memory

Sensory register
|
STM
|
LTM

Question 2

Evaluation of MSM

Answer 2

+ supporting evidence: any research from miller, Paterson & Peterson, Baddeley

+ case studies:
• HM- brain damage after operation, can’t make new memories
• Clive wearing- only recognise wife

• too simplistic: WMM produces contradictory evidence

Question 3

What is the working memory model (WMM) ?

Answer 3

• Baddeley & Hitch
• focuses on STM
• argues we have more than one STM store

       Central executive  |                     |                    | Visio           Episodic    Phonolo-  Spatial          Buffer       Logical  Sketch pad                      Loop   |                     |                    | 
     Long Term Memory

Question 4

Evaluation of WMM

Answer 4

+ support from dual task performance: Baddeley & hitch, 2 same parts= bad, 2 different parts= good

+ support from brain damaged patients: KF, motorcycle accident, poor STM

• biologically deterministic: case studies focus of one person. Not generalisable
• problems with central executive: vague, not clear, sounds the same as ‘ attention ‘ in MSM

Question 5

What is dual task performance ?

Answer 5

• if you do two things at once but one requires vision and other sound then you can perform both task’s successfully
