Social Perception is the study of how people form impressions of and make inferences about other people. We learn about others' feelings and emotions by picking up on information we gather from their physical appearance, and verbal and nonverbal communication. Facial expressions, tone of voice, hand gestures, and body position are just a few examples of ways people communicate without words. A real world example of social perception would be understanding that someone disagrees with what you said when you see them roll their eyes. Closely related to and affected by this is the idea of self-concept, a collection of one’s perceptions and beliefs about oneself.
