Social perception (or person perception) is the study of how people form impressions of and make inferences about other people as sovereign personalities. Social perception refers to identifying and utilizing social cues to make judgments about social roles, rules, relationships, context, or the characteristics (e.g., trustworthiness) of others. This domain also includes social knowledge, which refers to one’s knowledge of social roles, norms, and schemas surrounding social situations and interactions. People learn about others' feelings and emotions by picking up information they gather from physical appearance, verbal, and nonverbal communication. Facial expressions, tone of voice, hand gestures, and body position or movement are a few examples of ways people communicate without words. A real-world example of social perception is understanding that others disagree with what one said when one sees them roll their eyes. There are four main components of social perception: observation, attribution, integration, and confirmation.
