Atkinson-Shiffrin Model

The Atkinson-Shiffrin model, which is also known as the multi-store model or modal model, is a model of memory storage that was proposed in 1968 by researchers Richard Atkinson and Richard Schiffrin.

This model proposes that there are three different types of memory storage: short-term memory (STM), long-term memory (LTM), and a sensory register. Information passes through these different types in a one way, linear fashion and is similar to an information processing model (which are also used to model computer memory storage).

Like a computer, the multi-store model has three main stages of input, processing, and output.
