Perception is the process by which individuals organize and interpret their sensory impressions to make meaning of their environment. It involves stimulus, confrontation, interaction, registration, interpretation, feedback, behavior, and consequences. Perception is influenced by the perceiver's attitudes and experiences, the target, and the situation. Attribution theory examines how people determine if behavior is internally or externally caused. Selective perception means people interpret what they see based on their interests and experiences. Social perception concerns how individuals perceive others and involves factors like the halo effect, contrast effect, projection, and stereotyping.
