multi store model Flashcards
What passes into the sensory register?
Environmental stimulus
What are the two main stores in the sensory register?
Iconic and echoic
What is iconic memory?
Visual information coded visually
What is echoic memory?
Auditory info coded acoustically
Duration of sensory register
Less than half a second
Capacity of sensory register
Very high
How does info from the sensory register pass into STM?
If you pay attention to it
Capacity of STM
7 +-2
How is info in STM coded?
Acoustically
Duration of STM
30 seconds if not rehearsed
What is maintenance rehearsal?
Repeating info over and over again
How does STM info pass into LTM?
Maintenance rehearsal
LTM capacity
Unlimited
LTM duration
Long time
How is info in LTM coded?
Semantically
How is memory recalled from LTM?
Transferred to STM through retrieval
Evaluation - supporting research evidence
Baddeley - mix up acoustically similar words using STM
Mix up semantically similar words using LTM
STM and LTM are different
Evaluation - more than one type of STM
Shallice and Warrington studied amnesiac KF
KF’s STM for digits was poor when read out loud, better when reading to himself
Visual and auditory STM
Evaluation - more than one type of rehearsal
Craik and Watkins - type of rehearsal matters not amount of it
Maintenance rehearsal does not transfer info to LTM
Elaborative rehearsal needed for long term storage
Link info to existing knowledge or think about what it means
Evaluation - artificial materials
Digits, letters, words
Consonant syllables no meaning
Doesn’t apply to real life
Evaluation - more than one type of LTM
LTM is not unitary
Different types of LTM undermines model
