Which theorist is known for the development of a stage model of memory?

The theorist known for the development of a stage model of memory is Atkinson and Shiffrin. Their model, introduced in 1968, defines memory in terms of three distinct stages: sensory memory, short-term memory, and long-term memory. This framework provides a foundational understanding of how information flows through different types of memory processes, emphasizing the temporal sequence and the characteristics of each stage.

Sensory memory serves as the entry point, capturing fleeting impressions of sensory information. Following that, relevant information is transferred to short-term memory where it can be held for a brief period, and through rehearsal and encoding mechanisms, it can be further transferred to long-term memory, which has a much larger capacity and longer duration. The clarity and structure of this model have significantly influenced both research and educational practices related to memory, making it a pivotal contribution in the field of cognitive psychology.

In contrast, the other theorists mentioned have made significant contributions to the field of memory but do not specifically create a stage model. Piaget is recognized for his theory of cognitive development in children rather than memory stages. Ebbinghaus is known for his work on the forgetting curve and memory retention but did not propose a stage model. Baddeley is well-regarded for
