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:
“I have no purpose to introduce political and social equality between the white and black races. There is a physical difference between the two, which, in my judgement, will probably for ever forbid their living together upon the footing of perfect equality; and inasmuch as it becomes a necessity that there must be a difference, I ... am in favour of the race to which I belong having the superior position.”
—Abraham Lincoln (1809–1865)
