Atkinson-Shiffrin Model
The Atkinson-Shiffrin Model, proposed by psychologists Richard Atkinson and Richard Shiffrin in 1968, describes how information is processed in the human memory system. It consists of three main components: sensory memory, short-term memory, and long-term memory. Information first enters sensory memory, where it is briefly held before being transferred to short-term memory for further processing.
In short-term memory, information can be retained for a limited time, typically around 20 to 30 seconds. If the information is rehearsed or encoded, it can then move into long-term memory, where it can be stored for extended periods, potentially for a lifetime.
