Question

According to the atkinson shiffrin model name and describe the three stages of memory

Answer 1

Memory is not one thing. Rather, it is any process that allows us to use previously stored information. Such processes may be widespread in the brain, and each major brain system may have its own form of memory.
This insight occurred gradually to modern psychologists. It represented a major shift of emphasis in memory research. Ebbinghaus and other early memory researchers tended to think memories were stored whole, and there was only one form of memory.
By the mid to late 1960s, psychologists still thought of memory as a single system, but they were getting comfortable with the idea of human information processing. They realized that humans, like computers, had to acquire and organize information before remembering it.
In 1965 Atkinson and Shiffrin suggested that human memory was organized as a system with three stages. They elaborated on their idea in 1968, producing the following model of memory.
