Multi-store Model

Question 1

What is a model

Answer 1

A visual representation of how something works and allows predictions to be made about human behaviour. Version of reality that can reflect real life but deviates from reality to allow you to turn psychological diseases on and off

Question 2

What is significant about the MSM

Answer 2

It was the first model and is therefore very influential. The model isn’t completely accurate however was a good first attempt and provides testable predictions

Question 3

How many memory stores does it suggest people have and how do they differ

Answer 3

Three separate and distinct stores . Each differ in coding, capacity and duration. Its a linear sequential model meaning info passes through the stores in order

Question 4

What is the coding of the sensory register

Answer 4

Sensory is modality specific meaning its encoded the way which it entered

Question 5

Duration of sensory register

Answer 5

Less than one-hundredth of information which touches the human senses reaches the STM

Question 6

Capacity of sensory register

Answer 6

Very large we have to be able to take in lots of auditory information

Question 7

How does information transfer to the STM

Answer 7

If attention if focused on the STM it will be transferred to the STM

Question 8

Stores in the sensory register

Answer 8

iconic store- visual images kept for short period of time
echoic store- auditory senses kept for a short period of time
haptic store-sensory memory retains physical senses of touch and internal muscle tensions

Question 9

Coding of STM store

Answer 9

Acoustically

Question 10

Capacity of STM

Answer 10

7+/-2 items

Question 11

Duration of STM

Answer 11

18-30 seconds unless rehearsed (we know this from P&P study where they made p’s remember numbers in a trigram)

Question 12

How can information get lost in STM

Answer 12

Can get ‘pushed out’ due to STMs limited capacity

Question 13

Coding of LTM

Answer 13

Semantically

Question 14

Duration of STM

Answer 14

Potentially unlimited (Bahricks study of face recognition and free recall)

Question 15

Duration of LTM

Answer 15

Potentially infinite

Question 16

How does information enter the LTM

Answer 16

Moved from STM to LTM via maintenance rehearsal

Question 17

How does information get recalled from the LTM to the STM

Answer 17

It can be retrieved back to the STM

Question 18

Key points on the case study of HM

Answer 18

Had his hippocampus removed to help with his epilepsy

Question 19

A strength to the MSM is that there is supportive evidence from brain scans

Answer 19

Beardsley (1997) found the prefrontal cortex is active during STM tasks such as when making a decision but not when doing LTM tasks
