The Multi-Store Model of Memory Flashcards
Who proposed the multi-store model?
Atkinson and Shiffrin (1968)
What did Atkinson and Shiffrin (1968) propose?
The mult-store model
What is an important key feature of the multi-store model?
- Each store is unitary
- Linear pathway
- Rehearsal is needed in order for information to be passed
- Passive process
What do you need in order for information to go from the sensory store to the STM?
Attention
What do you need in order for information to go from STM to LTM?
Elaborative rehearsal
What kind of rehearsal is used to keep information the STM?
Maintenance rehearsal
What is SM?
Sensory memory
What is the capacity of SM?
Huge
What is the capacity of STM?
7+/-2
What is the capacity of LTM?
Unlimited
What is the duration of SM?
2 seconds or less
What is the duration of STM?
18 seconds
What is the duration of LTM?
Unlimited
What is the encoding of SM?
Depends of sense
What is the encoding of STM?
Mainly acoustic
What is the encoding of LTM?
Mainly semantic
How does the SM decay?
Trace decay
How does the STM decay?
Mainly displacement
How does the LTM decay?
Mainly Interference
Who found research supporting that the STM and LTM are different?
Baddeley (1966)
Which case study shows that multi-store memory is not fully explained?
KF
Why does KF show that the multi-store memory is not fully explained?
- Recall for when digits read out loud was poor
- BUT when recall of digits was when he read to himself was more accurate
How many types of rehearsals are explained in the multi-store memory?
1
How many types of rehearsals did Craik and Watkins (1970) argue there was?
2
What were the two types of rehearsals presented by Craik and Watkins (1970)?
- Elaborative
- Maintenance
Which type of rehearsal was added onto the multi-store memory?
Elaborative
What kind of validity is research into MSM lacking in due to the artificial materials?
External validity
Is the LTM oversimplified or under simplified in the MSM
Oversimplified
