Memory Flashcards
Primary memory:
Sensations outlast for some little time the objective stimulus which has occasioned them
Secondary memory:
The knowledge of a former state of mind after it has steady once dropped from consciousness
Types of episodic memory:
Sensory
Short term
Long term
Atkinson and shiffrin’s model is called
The modal multi-store model of memory
MSM 3 systems:
Sensory registers
Short term store
Long term store
Sensory registers
Brief sensory stores
Iconic and echoic
Short term store:
Primary memory held for seconds
Maintained by rehearsal
Limited capacity
Limited duration
Long term store:
Secondary memory
Unlimited capacity and duration
Sperling research:
Partial report procedure
12 item recall
Supports brief sensory store
Max recall 4/5 items
Sperling research if immediate recall in one row
Close to 100%
Sperling: recall delayed by 1 second after stimulus performance
30% recall
How can memory be tested?
Free recall
Cued recall
Recognition
Relearning
Studies supporting we have a limited capacity visual store:
Averbach
Sperling
The serial position curve
Primacy- rehearsal
Flat mid curve- transfer to LTS
Recency - capacity of STS
In the MSM what transfers info from STS to LTS
Rehearsal
Rehearsal not always necessary:
Flat part of serial position curve not at 0 even for unrehearsed items
Rehearsal not always sufficient:
Does not always work
Maintence vs Elaborative rehearsal
How is info lost out of STS
Decay
MSM model:
Sensory Input, short term store, long term store
What did Shallice and Warrington find?
STM deficits not as devastating to LTM as expected
How do Baddeley and Hitch simulate STM deficits?
By using tasks that should fill up the STS (string of digits)
