the multi-store model

Question 1

how does information move between sensory register to short term memory

Answer 1

attention

Question 2

how does information stay in the short term memory

Answer 2

maintenance rehearsal

Question 3

how does information move from the short term memory to the long term memory

Answer 3

prolonged rehearsal

Question 4

how does information move from the long term memory to the short term memory

Answer 4

retrieval

Question 5

what are the features of the sensory register (coding, capacity and duration)

Answer 5

coding = according the the sense or mode in which it is received - modality specific

duration = very short, iconic is 250 milliseconds

capacity = potentially unlimited

Question 6

what is the capacity of STM and outline the linking research

Answer 6

• 7 +/- 2 chunks (Miller)
• Jacobs - digit span task, letters = 7.3, numbers = 9.3

Question 7

what is the duration of short term memory and outline the linking research

Answer 7

• Peterson and Peterson - trigram, 3 digit number counted back in 3, longer duration for each
• 18-30 seconds

Question 8

how is information coded in short term memory and outline the linking research

Answer 8

• Baddeley - 4 groups of words, asked to recall words in same order, acoustically similar group performed worst
• Acoustically

Question 9

how is information coded in long term memory and outline the linking research

Answer 9

• Baddeley - Ps recalled 20 minutes later, semantically similar performed worst
• Semantically

Question 10

what is the duration of long term memory and outline the linking research

Answer 10

• Bahrick et al - graduates aged 17-74 years old asked to recognise, graduates from last 15 years 90% accurate photo recognition, graduates form the last 48 years 70% accurate photo recognition
• long time/lifetime

Question 11

what is the capacity of long term memory

Answer 11

• unlimited, no research has found a capacity

Question 12

strengths of MSM

Answer 12

• HM - had brain surgery to help with epilepsy, lost ability to form new long term memories, supports the idea of separate stores

Question 13

weaknesses of MSM

Answer 13

• artificial tasks e.g. Peterson and Peterson trigrams - limits the extent of generalisability therefore lacks ecological validity
• reductionist - doesn’t consider the different types of LTM and therefore is a limited explanation
• KF - verbal short term memory was affected but visual wasn’t, suggests STM has further sub-stores (WMM)
