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
