Memory- MSM

Question 1

What are the stores in the MSM?

Answer 1

Sensory register, short-term memory, long-term memory

Question 2

What are the features of each store in the MSM?

Answer 2

Coding, capacity and duration

Question 3

Describe what is meant by coding (2 marks)

Answer 3

-This is how we process information – changing it to a suitable form so that it can be stored
-e.g the STM code acoustically

Question 4

Describe what is meant by capacity (2)

Answer 4

• this is the amount of information that can be held in memory
  -e.g the capacity of the STM is 5 to 9 items

Question 5

Describe what is meant by duration (2)

Answer 5

-this is how long the information last in the memory
-e.g information last 18 to 30 seconds in the STM

Question 6

How does sensory register code?

Answer 6

Modality specific

Question 7

What is the capacity of the sensory register?

Answer 7

Unlimited

Question 8

What is the duration of the sensory register?

Answer 8

Limited (less than 0.5 seconds)

Question 9

How does the STM code?

Answer 9

Acoustically

Question 10

What is the capacity of the STM?

Answer 10

7+/-2 items

Question 11

What is the duration of STM?

Answer 11

Limited, 18 to 30 seconds

Question 12

How does the LTM code?

Answer 12

Semantically

Question 13

What is the capacity of the LTM?

Answer 13

Unlimited

Question 14

What is the duration of the LTM?

Answer 14

Potentially a lifetime

Question 15

Who conducted the research study into coding of the STM and summarise what they did

Answer 15

-Baddeley
-STM codes acoustically as there was better recall with acoustically dissimilar words

Question 16

Who conducted the research study into the coding of the LTM and summarise what they did

Answer 16

-Baddeley
-LTM code semantically as there was better recall with semantically dissimilar words after a 20 minute prevention task

Question 17

Who conducted the research study into the capacity of the STM and summarise what they did

Answer 17

-Miller
-found that it was limited. 5 to 9 items were recalled using the digit span technique.

Question 18

Who conducted the research study into capacity of the LTM and summarise what they did

Answer 18

The LTM has to be unlimited so we can make new memories. You can’t possibly research it.

Question 19

Who conducted the research study into the duration of the STM and summarise what they did

Answer 19

• Peterson & Peterson
  -18 to 30 seconds, however maintenance rehearsal will increase duration

Question 20

Who conducted the research study into the duration of the LTM and summarise what they found

Answer 20

-Bahrick
-information can last potentially lifetime. recall of classmates remained accurate after 48 years improved with the use of correct cues (photos)
