Multistore model of memory

Question 1

What is the multistore model of memory

Answer 1

Describes the flow between three permanent storage systems of memory.

Question 2

Who developed the MSM theory

Answer 2

Atkinson and Shiffrin 1968

Question 3

What is sensory memory

Answer 3

Where information from the senses is stored. Whichever sense is registered will match the way it is consequently held.

Question 4

What is Short term memory

Answer 4

Sensory information moves into the STM for temporary storage. Capacity increased through chunking.

Question 5

What is long term memory

Answer 5

Once information os rehearsed via the rehearsal loo[ it consolidates it to the LTM

Question 6

What is the coding, capacity and duration of sensory memory

Answer 6

Coding- sensory form
capacity- very large
duration- a few milliseconds

Question 7

What is the coding, capacity and duration of STM.

Answer 7

Coding- Acoustically, visually
capacity- 7 +/- 2
duration <30s

Question 8

What is the coding, capacity and duration of LTM

Answer 8

Coding- semantically
capacity- unlimited
duration- a lifetime

Question 9

Strengths of the MSM

Answer 9

+lots of research supporting the distinction (HM)
+Influenced other research (WMM)

Question 10

Weaknesses of MSM

Answer 10

• Simplified description
• Insignificant stimuli remembered
• We can only assume LTM is unlimited
• New LTM can be made without rehearsal

Question 11

HM

Answer 11

Hippocampus removed to relieve epilepsy- couldn’t form new ltm memories but could do well on STM tasks. Communication between LTM and STM was damaged.

Question 12

New LTM can be made without rehearsal

Answer 12

How much is processed is more important.
Craik and Tulving words processed more deeply were more likely to be recalled.
