MSM

Question 1

What is encoding?

1

Answer 1

• Format that info is stored in various memory stores

Question 2

What is retrieval?

1

Answer 2

• Process of transferring info from LTM-STM, recalling info

Question 3

What is capacity?

1

Answer 3

• Amount of info that can be held in a memory store

Question 4

What is duration?

1

Answer 4

• Length of time info can be held in memory

Answer 5

STM and LTM = qual different. Baddley (1966) found we mix up words that sound similar using STM. Mix up words that have similar meanings (LTM). Encoding in STM is acoustic, LTM semantic

1+ STM store. Shallice and Warrington studied KF. His STM for digits was poor read out loud to him. ^Recall when he read digits himself. Separate stores for visual/auditory info

^Mem. Research shows limited capacity of STM can be ^ through a process called ‘chunking’. By putting digits into bigger chunks, number of items to be stored is less

Question 6

What is the sensory register and how many stores does it consist of?
2

Answer 6

• All stimuli from the environment pass into the SR

- 1 for 5 senses

Question 7

What are the features of sensory register e.g. duration, capacity and key process?
3

Answer 7

• Duration = less than half a second
• Capacity = high
• Key process = attention, pass further in mem system (STM)

Question 8

What is the STM and what are the features e.g. duration, capacity and how is it encoded?
4

Answer 8

• Temporary store
• Capacity = 7+-2 items (Millers magic number)
• Encoded = acoustically (Baddley 1966a)
• Duration = 18-30 seconds (Peterson)

Question 9

What is long term memory?

1

Answer 9

• Permanent long term memory store for material that’s been rehearsed for a prolonged period of time

Question 10

What are the features of LTM e.g. capacity, how is it encoded and duration?
3

Answer 10

• Capacity = unlimited
• Encoded = semantically (Baddley 1966b)
• Duration = Students able to recognise faces of classmates almost 50yrs on (Bahrick et al.)
