What is the modal model of memory?

The modal model of memory, proposed by Atkinson and Shiffrin in 1968, describes memory as comprising three distinct components: sensory memory, short-term memory, and long-term memory. Sensory memory briefly holds incoming sensory information, short-term memory processes and retains information for a limited duration, and long-term memory stores information indefinitely. The model emphasizes the flow of information through these stages, highlighting the importance of attention and rehearsal in transferring information from short-term to long-term memory. Overall, it provides a foundational framework for understanding how we encode, store, and retrieve memories.
