Multi- Store Model Of Memory Flashcards
Who was the multi-store model of memory proposed by?
Atkinson and Shiffrin
What is the multi-store model of memory?
It explains that information must be rehearsed for information to be transferred from short term memory to long term memory.
What are the components of the model?
- Sensory memory
- Short term memory
- Long term memory
What is the sensory memory?
Allows for the immediate perception of environmental stimuli. It has several stores (one for each of our senses).
How long can the information in the sensory memory last for?
Information is rapidly lost from sensory memory less than 1 second
What must happen in order for the sensory information to move to short term memory?
Attention must be paid otherwise it decays (without attention)
How much can short term memory store?
According to Miller, 1956, it can hold up to 7+ / -2 items.
How long can short term memory store information?
For 18-30 seconds
How can the capacity of short term memory increase?
By chunking information
What happens if information is not rehearsed in the short term memory?
It is forgotten by decay or displacement
What is elaborative rehearsal?
Linking new information with information you already know to move information into your long-term memory. Creating associations, personal connections, restating information or organising concepts in a personal way (e.g. mind map)
How much capacity does long term memory have?
Unlimited capacity
How long can long term memory retain information?
For potentially up to a lifetime
How is long term memory encoded?
Long term memory is encoded semantically (based on meaning)
How is information forgotten in long term memory?
Information is forgotten by decay or interference
