Information Processing Theory is a cognitive framework that compares the human mind to a computer. It suggests that information is received, processed, stored, and retrieved in a systematic way. This theory emphasizes how we take in sensory information, encode it into our memory, and later retrieve it when needed. The theory is often divided into stages: input, processing, and output. During the input stage, sensory data is collected. In the processing stage, the brain organizes and interprets this data. Finally, in the output stage, the information is expressed through actions or verbal responses.
