Multi-store Model

Question 1

State the three components of the MSM

Answer 1

1. Sensory register
2. STM
3. LTM

Question 2

Name the researchers who developed the MSM

Answer 2

Atkinson and Shiffrin (1968)

Question 3

State the coding, capacity, and duration of the sensory register

Answer 3

Coding: sensory specific
Duration: limited (milliseconds)
Capacity: very large

Question 4

State the coding, capacity and duration of STM

Answer 4

Coding: acoustic
Duration: very limited (18 seconds)
Capacity: limited (7+/-2 chunks)

Question 5

State the coding, capacity and duration of LTM

Answer 5

Coding: semantic
Duration: lifetime
Capacity: unlimited

Question 6

Define maintenance rehearsal

Answer 6

Repeating information over and over in order to keep it in your STM

Question 7

Define prolonged rehearsal

Answer 7

Rehearsing information for long enough that it transfers from our STM into our LTM

Question 8

Define attention

Answer 8

Information from the environment that we notice is transferred from the sensory register to the STM

Question 9

Define retrieval

Answer 9

The process by which we transfer material back into our STM from our LTM so that we can recall it

Question 10

Name and outline a case study which shows support for MSM

Answer 10

Patient HM (Scoville and Milner, 1957):
-HM suffered from epilepsy and had his hippocampus removed during surgery (plays a central role in memory)
-After surgery, his LTM was damaged: read the same magazine repeatedly without remembering it and couldn’t recall what he had eaten earlier the same day
-STM was still intact: he performed well on tests of immediate span
