Describe the three stages of human information processing.

What will be an ideal response?

During the input stage, information is taken in via the senses, attended to, and then interpreted. This is the stage where raw information is taken in through the senses and interpreted by the brain. Once information has passed through the perceptual filters, it is processed into memory. Memory involves maintaining information over time. Cognitive psychologists recognize two kinds of memory--short-term and long-term memory. Once information has been stored, it is relatively useless unless it can be retrieved. Information that has been stored for a lifetime can be recalled in an instant. Other times, however, recently stored information seems very difficult to recall.
