Multistore model Flashcards
What approach is the multi-store model from?
Cognitive approach
What are the three compartments of the Multi-store model?
- Sensory register
- Short-term memory
- Long-term memory
How does information move in the Multi-store model?
Linearly, it enters at the sensory register and is passed along through a series of processes
What needs to happen for information to pass from the sensory register to the short term memory?
Attention
How can duration be extended in the Short term memory?
Maintenance rehearsal
How can information pass from the Short term memory to the Long term memory?
Prolonged rehearsal
How, according to the multi-store model, do we respond?
Information is retrieved from the Long term memory to the short term memory where we can respond
When can forgetting occur in the Multi-store model?
At any stage
What is Capacity?
The amount of information a store can hold
What is the capacity of the Sensory register?
Very large
What is the capacity of the Short term memory?
7 letters 9 digits (7+/-2)
What is the capacity of the long term memory?
Unlimited
What is duration?
The length of time information can be held for
What’s the duration of the sensory register?
Very short, a few milli seconds
What is the duration of the short term memory?
Limited - 20 seconds
What is the duration of Long term memory?
Life time
What is coding?
The way in which information is processed
What is the coding of the sensory register?
Its modality free - not one type
What us the coding of the short term memory?
Acoustic
What is the coding of the Long term memory?
Semantic
What study tested the capacity of the Short term memory?
Jacobs’ digit span test
- P’s would see a letter or number and have to recall it and every time the amount would increase: Avg letter = 7.3 Avg number = 9.3
What study tested the duration of short term memory?
Peterson and Peterson’s nonsense trigrams
- P’s would get 3 random letters and have to then count back in 3s from 100 for a duration of time and then recall the letters: The longest they could go without maintenance rehearsal was 20 seconds
What was the test for duration of Long term memory?
Barick’s yearbook recall
- He tested P’s ability to recall their class, in one group with photos and one group without: 90% could match faces 14 years later and 60% could match faces 47 years later
What was the test of coding for both long term and short term memory?
Baddeley’s acoustic semantic test
- 8 groups learnt 4 different sets of words and had to recall them at the time or a week later: words which were acoustically similar were recalled worse immediately and semantically similar words were recalled worse a week later
Why does Clive wearing cause doubt in the Multi-store model?
His episodic memory failed after his accident but his procedural and semantic still worked meaning it is not a single store
How does patient HM support the theory?
Patient HM could access short term memory but not long term memory thus proving they were different stores
