How do psychologists describe the human memory system?

''Psychologists use memory models to think and communicate about memory. Information-processing models involve three processes: encoding, storage, and retrieval. The connectionism information-processing model views memories as products of interconnected neural networks. The three processing stages in the Atkinson-Schiffrin model are sensory memory, short-term memory, and long-term memory. More recent research has updated this model to include two important concepts: (1) working memory, to stress the active processing occurring in the second memory stage; and (2) automatic processing, to address the processing of information outside of conscious awareness.''
