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:
“Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.”
—Susanne K. Langer (1895–1985)
