Multi-store memory

Question 1

Who researched the multi-store memory ?

Answer 1

Atkinson and Shifrin

Question 2

What are the three main components to the multi-store model of memory ?

Answer 2

• Sensory register
• short-term memory
• long-term memory

Question 3

What are the coding, capacity and duration of the sensory register ?

Answer 3

Coding = modality specific
Capacity = high
Duration = 0.5 secs

Question 4

What are the coding, capacity and duration of the short-term memory ?

Answer 4

Coding = acoustic
Capacity = 7 (plus or minus 2)
Duration = 15-30 secs

Question 5

What are the coding, capacity and duration of the long-term memory ?

Answer 5

Coding = semantic
Capacity = unlimited
Duration = lifetime

Question 6

What is acoustic also referred to in the sensory register ?

Answer 6

Echoic

Question 7

What is visual also referred to in the sensory register ?

Answer 7

Iconic

Question 8

What are evaluative points of the multi-store memory ?

Answer 8

Positive =support from studies showing that STM and LTM are different
- Baddeley found we tend to mix up words that are similar when using our STM’s

Negative = There is research that shows that there is multiple types of STM
- Shallice and Warrington studied a client called KF
- had a clinical memory disorder - amnesia
- Their STM was digits was poor when read aloud to him
- Recall was much better when he read the digits to himself
- shows there could be another STM for non-verbal sounds (e.g noises)
- shows the MSM is wrong in claiming there is just one type of STM store for processing
