The document discusses perception and the perceptual process. It explains that perception involves selecting stimuli from the environment, organizing those stimuli, and interpreting them. In selection, external factors like color and internal factors like interests influence what we perceive. Organization involves grouping stimuli by proximity, similarity, closure and other factors. Interpretation is subjective and involves judgment, attitudes, and stereotypes. Perception can be influenced by characteristics of the perceiver, target, and situation. Common perceptual errors discussed are stereotyping and the halo effect.
