This document provides an overview of the information processing model of learning and memory. It explains that the model involves three main stages: encoding, where information is received and processed; storage, where information is kept in either short-term or long-term memory; and retrieval, where stored information is recalled. The document also discusses Atkinson and Shiffrin's modal, which proposed three memory stores: sensory register, short-term memory, and long-term memory. It notes that the information processing model offers advantages for improving retention and retrieval but has limitations regarding computer versus human processing capacity.
