multi store model

Question 1

who proposed this model?

Answer 1

Atkinson and Shriffrin (1968)

Question 2

what is this models explanation for the sensory register?

Answer 2

• duration = less than 1/2 sec
• capacity = high
• coding + iconic and echoic

Question 3

what is this models explanation for STM?

Answer 3

• duration = 18-30 secs w/o rehearsal
• capacity = 5-9 items (limited)
• coding = acoustic

Question 4

what is this models explanation for LTM?

Answer 4

• duration = unlimited
• capacity = unlimited
• coding = semantic

Question 5

what does information need to be passed from the sensory register to STM?

Answer 5

attention

Question 6

what type of rehearsal is needed to transfer information from STM to LTM?

Answer 6

maintenance

Question 7

what type of rehearsal is needed for information to remain in LTM?

Answer 7

prolonged and retrieval

Question 8

what are the main evaluation points of the multi store model?

Answer 8

1) research support from Baddeley - there are two memory stores that are independent
2) only explains one type of rehearsal (limited) - Craik and Watkins explains elaborative rehearsal
3) LTM is oversimplified (described as a unitary store) BUT we have semantic, episodic and procedural stores
