Atkinson-Shiffrin's "Multi Store" Memory Model
Sensory Memory (The Sense Organs One Second Memory)
Iconic Memory (Visual)
Shape
Colour
Size
No meaning to images
Echoic Memory (Audio)
Provides "Auditory Stimuli"
Short-term Memory
Information is taken from sensory memory
Retains information long enough for us to use it
Typically lasts 15-30 seconds unless people rehearse it
"Miller" suggests that the STM can hold up to 7(+/-2) chunks of information
Long Term Memory
Provides Lasting Retention of memory
Limitless capacity
Can last from minutes to an infinite amount of time
Encoded in terms of meaning (semantic memory)
Also retains procedural skills and imagery
Recieves from STM via repetition and rehearsal
Can also recieve from Sensory Memory but unusual
Criticism
Linearity
Agued that the MS model is way too linear
Does not accomodate the subdivisions of STM and LTM
Does not pattern with the neurological explanations of where the memory is stored
Does not explain cases where the STM is impared but the LTM is not as information must be able to pass through the STM first
Monolithicity
Some studies have shown a limitation in the LTM capacity
It is thought that the memory cannot be split into three definitive stores
Cases such as Autistic Savants disband the theory of repetition showing ability to remember precise figures from LTM
