Memory Flashcards
What is capacity
A measure of how much information can be stored in the LTM and STM
What is duration
Measure of how long information be held in the memory
What is encoding
The form in which information is stored in memory
How much information and capacity does the STM hold
Small ammount of information and has a limited capacity
How much information and capacity does the LTM hold
Unlimited ammount of information and has a large capacity
focused on cognitive overload
What did Miller (1956) come up with
Magic number 7 plus and minus 2
How can the capacity be extended in STM
- Chunking information
- combining small peice of information
How is STM and LTM encoded
- STM - Acoustic (sound)
- LTM - Semantic (meaning)
What did Baddeley (1996) experiment show
- STM is largely based on acoustic code
- Particiapnts remembered fewer acoustically simillar words then acousitcally disimillar
Leaving school
Bahrick (1975) what did he find in his study of LTM
Within 48 years of leaving school 75% of his particiapnts can still remember the faces nad names of their school friends
Who proposed the idea of the multi store memory model
Atkinson and Shiffrin (1968)
Three stores in Multi store model
- Sensory memory store
- STM
- LTM
Explain the three stages of multi store model
- Sensory information is perceived (what we see or hear)
- sensory information is transferred to STM where it is maintaned by rehearsal (If not information is lost or replaced)
- Information from STM is transferred to the LTM by enough rehersal
What is a strength of the multi store model
Simple and can be tested
What is a weakness of the multi store model
- Artificial ‘free recall’ experiments dosen’t reflect real life situation of how memory is created
- Model suggest memory is a passive process where as the reconstructive memory suggest that memory is an active process
What is reconstructive memory
How we store and remember LTM in socal and cultural processes
What are the three types of long term memory
- Episodic
- Semantic
- Procedural
What is episodic memory
This is the memory of autobiographical events such as times, places etc that can be explicitiy stated
What can you use episodic memory for
- Remember events
- Use during recollection to retrive contexual information of a specific event
