The model of human memory proposed in 1968 by Atkinson and Shiffrin has the distinction of having revolutionized information-processing theory. It catapulated a whole generation of cognitive psychologists into sustained research programs that continue to be productive year after year. The book's notable authors analyze and deliberate on the model's monumental scientific contributions to human learning and memory. They also challenge it and delve into its likely future evolution and impact on learning and memory. The volume was published in celebration of the 30th anniversary of the Atkinson-Shiffrin model and sets forth a provocative future for memory workers and learning theorists.
