Memory: topic 2 ‘multi store model of memory’ Flashcards
1
Q
What is a model of memory?
A
- a model of memory is a basic idea of how the memory system operates and the various parts that make up the memory system / how the parts work together
2
Q
Who created the multi-store model of memory?
A
- Atkinson and Shiffrin 1968
3
Q
What is the MSM claimed to be made up of?
A
- claims that memory is made up of three stores linked my processing
4
Q
What 3 are the components in the MSM?
A
- sensory register, short term memory and long term memory
5
Q
What is the sensory register?
A
- where information is held at each of the 5 senses: sight, smell, touch, taste and sound
6
Q
What is the sensory register constantly doing?
A
- receiving and coding modality-specific information, but most of this receives no attention
7
Q
What is the capacity and duration of the sensory register?
A
- very large capacity
- very limited duration, so incoming data remains here for a very brief period
8
Q
How is data encoded and transferred into the STM from the SR?
A
- when the persons attention is focused on the SR
- codes through acoustic coding (based on how the information sounds)
9
Q
How are STM’s lost and why?
A
- through displacement
- STM can only hold about 7+/- 2 items so if this is overloaded, old info may be pushed out or decayed
10
Q
What is the capacity of STM?
A
- 7+/-2 items
11
Q
What is the duration of STM?
A
- 18-30 seconds
12
Q
How do short term memories fade?
A
- memories will fade if maintenance rehearsal does not take place
13
Q
How is information transferred from STM to LTM?
A
- if info is rehearsed and understood (elaborative rehearsal) then it will be transferred to the LTM store
14
Q
How is LTM coded?
A
- semantically (based on meaning)
15
Q
What is the capacity of LTM?
A
- LTM can hold an unlimited amount of info and can hold it for up to a lifetime
