Memory Flashcards
What is capacity?
maximum amaount of information memory can hold
What is coding
how memory modifies information so it can be stored
What is duration?
length of time a memory stays stored
Multi-store model (MSM)
Who proposed the multi-store model?
Atkinson and Shiffrin 1968
Multi-store model (MSM)
What is the multi store model?
memory divided into a model of stages information passed through
Multi-store model (MSM)
What are problems with MSM?
- oversimplifies memory
- no account for different types of things to remember
Sensory memory
What is sensory memory?

Memory
What are the stores for encoding ?
- acoustic - sound
- visual - appearance
- semantics - meaning
Short term memory (STM)
What is the main way of encoding in STM?
Acoustic
Short term memory (STM)
Where does evidence of encoding come from?
Substitution errors
Short term memory (STM)
What are substitution errors?
when people substitute information for similar information that needs to be learnt - likely to confuse info
Long term memory (LTM)
What is long term memory?
storage of info over a long period of time with potentially unlimited storage
Long term memory (LTM)
How long does it take for info to be transferred to LTM?
30 seconds
