Atkinson's and Shriffin Multi Store Model of Memory (1968)

Question 1

Role of Attention in memory?

Answer 1

• We register the information briefly, but we do not pay attention to all of it.
• When we do pay attention to the sensory information, it goes into the STM.

Question 2

Duration and capacity of STM

Answer 2

• When information goes into the STM, it is stored for about 15-30 seconds
• If we rehearse the information, it can be stored in the STM for longer
• STM is modality free (Stores different type on info from different senses)

Question 3

Role of Rehearsal in Memory?

Answer 3

Multi store model of memory suggests that if the info is rehearsed over and over again, it stays in the STM for longer, if info is rehearsed for longer, it is transferred to LTM

Question 4

Explain primacy and recency effect by Ben Murdock

Answer 4

• Info at the start of the list is recalled because it is rehearsed and transferred to the LTM
• Info at end of the list is still in the STM
• Info in the middle of the list is rehearsed less because there was less time

Question 5

Advantages

Answer 5

• There is evidence that supports the theory of two separate memory stores.

Question 6

Disadvantages

Answer 6

• Overstates the role of rehearsal in terms of transferring information in the LTM.
• We do not need to rehearse every piece of information to remember - We remember things because they are meaningful.
• Unlikely that we have two types of LTM store.
