There are four steps of perception as a social information process, and they are selective attention/comprehension, encoding and simplification, storage and retention and retrieval and response. Put simply, this means that a person observes the presenting person or object, interprets what he sees based on current knowledge, stores this interpretation into his memory and makes decisions and judgments based on this memory.
The study of perception relating to how people learn to perceive one another is called "social cognition." It is also known as "social information processing." It studies how people believe that they think about other people and how they actually think about other people. It studies how someone's perception of another person influences the way he interacts with that person. It also addresses the way that person views himself.
Perception is a process that people use to recognize and better understand the world around them. It helps them to recognize the familiar and identify the unfamiliar. Even animals use perception to recognize favorite foods and toys or familiar sounds. Reading is a form of perception that involves people remembering and identifying the sequence of letters and words from the alphabet that create meaning. People use perception daily in order to appropriately function within their environment.
