This document provides an introduction to individual behavior and perception. It defines behavior as a person's response to stimuli, which can be influenced by factors like culture, attitudes, emotions, values, ethics, authority, and coercion. Studying individual behavior allows people to understand their own patterns, take responsibility for managing themselves, and develop self-competency. Perception is how people organize and interpret sensory information to make sense of their environment. A person's perception is influenced by characteristics of the target, perceiver, and situation. Perceptual errors can occur through processes like selective perception, halo effects, contrast errors, projection, stereotyping, and expectancy effects.
