This document discusses perception and how it influences how people view and understand the world. It defines perception as how individuals select, organize, and evaluate environmental stimuli. Selective perception means people focus on certain features while ignoring others. Perception is influenced by past experiences, attitudes, and motivations. Schemas and neural networks shape people's mental templates for interpreting stimuli. Common perceptual distortions include stereotyping, halo effects, projection, and self-fulfilling prophecies. Understanding perception is important for effective communication and avoiding misunderstandings between groups.
