Multi Store Model of Memory Flashcards
What does memory involve? (3)
the encoding, storage and retrieval of information
who came up with the MSM?
Atkinson & Shiffrin
3 memory stores of the MSM
- sensory memory
- short term memory
- long term memory
how long does sensory memory hold information for?
0.5 seconds
how much and for how long does short term memory hold information for?
7 items for 30 seconds
how much and for how long does long term memory hold information for?
unlimited items for an unlimited amount of time
types of encoding (5)
- Visual
- Acoustic
- Semantic
- Episodic
- Procedural
Results of Baddeley’s study of encoding - STM
over a short time, participants made more mistakes in the list of acoustically similar words, suggesting that the STM uses acoustic encoding
Results of Baddeley’s study of encoding - LTM
after a delay, participants made more mistakes in the list of semantically similar words, suggesting that LTM uses semantic encoding
rehersal
extends the time that information can be stored in the STM for
chunking
breaking up large information eg phone numbers into smaller chunks is more effective than rehersal
serial position effect
where objects at the start and end of a list are remembered better than objects in the middle
primacy
when you the first few objects in a list well
