Characteristics of the perceived person, object, or event -- such as contrast, intensity, figure-ground separation, size, motion, and repetition or novelty -- are important in the perceptual process.

Figure-Ground Separation

Figure-ground separation is a concept in perception and visual design where the main subject (figure) is perceived as separate and distinguishable from the background (ground).

Perceptual Process

The sequence of steps that includes the reception and interpretation of sensory information by the brain, leading to an understanding of the environment.

Contrast

The difference in luminance or color that makes an object distinguishable from others and the background.
