Atkinson-Shiffrin memory model

The Atkinson–Shiffrin model (also known as the multi-store model or modal model) is a model of memory proposed in 1968 by Richard Atkinson and Richard Shiffrin. The model asserts that human memory has three separate components:

1. a sensory register, where sensory information enters memory,
2. a short-term store, also called working memory or short-term memory, which receives and holds input from both the sensory register and the long-term store, and
3. a long-term store, where information which has been rehearsed (explained below) in the short-term store is held indefinitely.
