Physical Characteristics
The brain disassociates objects from one another based upon the differences between their physical characteristics. These characteristics fall into four categories: color, size, alignment, and character. The category of color encompasses the hue, saturation, value, and perceived texture of forms. Size describes the surface area of a form. Alignment is the arrangement of forms with respect to their direction, orientation, or pattern. Character is the rectilinearity and curvilinearity of forms. Forms that have differences in these characteristics contrast each other.

Famous quotes containing the word physical:
“... life is moral responsibility. Life is several other things, we do not deny. It is beauty, it is joy, it is tragedy, it is comedy, it is psychical and physical pleasure, it is the interplay of a thousand rude or delicate motions and emotions, it is the grimmest and the merriest motley of phantasmagoria that could appeal to the gravest or the maddest brush ever put to palette; but it is steadily and sturdily and always moral responsibility.”
—Elizabeth Stuart Phelps (1844–1911)
