Non-Human Animals
Animals share a non-verbal system for representing number as analogue magnitudes. Animals have been known to base their rationality on Weber’s Law. This historically important psychological law quantifies the perception of change in a given stimulus. The law states that the change in a stimulus that will be just noticeable is a constant ratio of the original stimulus. Weber’s Law describes discriminability between values based on perceptual continua such as line length, brightness, and weight.

Famous quotes containing the words non-human and/or animals:
“Almost like a god looking at her terribly out of the everlasting dark, she had felt the eyes of that horse; great glowing, fearsome eyes, arched with a question, and containing a white blade of light like a threat. What was his non-human question, and his uncanny threat? She didn’t know. He was some splendid demon, and she must worship him.”
—D.H. (David Herbert)
“Old women snore violently. They are like bodies into which bizarre animals have crept at night; the animals are vicious, bawdy, noisy. How they snore! There is no shame to their snoring. Old women turn into old men.”
—Joyce Carol Oates (b. 1938)
