Perception is the set of unconscious processes we undergo to make sense of the stimuli and sensations we encounter.
Selection, the first stage of perception, is the process through which we attend to some stimuli in our environment and not others.
Organization is the stage in the perception process in which we mentally arrange stimuli into meaningful and comprehensible patterns.
Interpretation, the final stage of perception, is the subjective process through which we represent and understand stimuli.
Perceptual constancy is perceiving objects as having constant shape, size, and color regardless of changes in perspective, distance, and lighting.
