Paper 1- Memory: Multi Store Model Of Memory Flashcards
Who devised the multi store model?
Atkinson and shiffrin
When was the MSM devised?
1968
What does the MSM explain ?
How information flows through a series of storage systems
What are the tree permanent structure in the memory ?
Sensory register
Short term memory
Long term memory
How does easy stage of the memory differ ?
Coding
Capacity
Duration
What is coding?
The form in which information is stored
What is capacity
How much information can be stored
What is duration ?
How long information can be stored for
What is the sensory register ?
An automatic response to the reception of sensory information by sense organs
What is the echoic store for?
Auditory information
What is the iconic store for?
Visual information
Why does only some information pass through the sensory register ?
Because only certain amounts of information are Paied attention to
Explain the coding research for the sensory register ?
CROWDER 1993- information is only retained in iconic store for milliseconds
In the echo if for two to three seconds
SUPPORTS: idea that we code information in different stores and for different durations of time
Explain research for capacity in the sensory register
SPERLING 1960- used a tachistoscope
Flashed 3 x4 array of letters onto decree for 1/20th of a seconds
Sounds were in different tones to indicate which line to recall - High medium and low
Recall was high which supports the capacity of the SR being large
Evaluate the capita of the SR
It involves experiments
Experiments only provide an estimate
The lack in mundane realise
Lack in ecological validity
What is said to be the duration of the Sensory register ?
To have a limited duration
Each type of store decays at different rates
Other evidence suggests that duration decreases with age
Explain the research for the duration of the SR?
WALSH AND THOMPSON 1978-
Found that the iconic store has a duration of 500 milliseconds
Decreases as you get older
Duration of the sensory memories is limited and dependent on age
TREISMAN 1964- played identical auditory information into both ears of ppts with a delay between each
Ppts noticed info was same if delay of 2 seconds or less
Suggests that the echoing store therefore had a duration of 2 seconds
Evaluate the duration of the sensory register
Breuer duration of sensory memories due to engrams fading quickly
Biological basis
Evolutionary- only need to focus on perceptual information with an immediate survival value
What is the short term memory ?
It receives information from the SR
It’s an active change in memory
Contains information currently being thought about
