Atkinson-Shiffrin's "Multi Store" Memory Model

Atkinson and Shiffrin's multi-store model of memory outlines three key components: short-term memory (STM), long-term memory (LTM), and sensory memory. STM temporarily holds information for 15-30 seconds unless rehearsed, with a typical capacity of about seven chunks.

Criticism

Monolithicity
Cases such as Autistic Savants disband the theory of repetition showing ability to remember precise figures from LTM
It is thought that the memory cannot be split into three definitive stores
Some studies have shown a limitation in the LTM capacity
Linearity
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
Does not pattern with the neurological explanations of where the memory is stored
Does not accomodate the subdivisions of STM and LTM
Agued that the MS model is way too linear

Long Term Memory

Recieves from STM via repetition and rehearsal
Can also recieve from Sensory Memory but unusual
Encoded in terms of meaning (semantic memory)
Also retains procedural skills and imagery
Can last from minutes to an infinite amount of time
Limitless capacity
Provides Lasting Retention of memory

Short-term Memory

"Miller" suggests that the STM can hold up to 7(+/-2) chunks of information
Typically lasts 15-30 seconds unless people rehearse it
Retains information long enough for us to use it
Information is taken from sensory memory

Sensory Memory (The Sense Organs One Second Memory)

Echoic Memory (Audio)
Provides "Auditory Stimuli"
Iconic Memory (Visual)
No meaning to images
