The Power of Symmetry; April/May/June 2009; Scientific American Mind; by Vilayanur S. Ramachandran & Diane Rogers-Ramachandran; 3 Page(s)
The aest hetic appeal of symmetry is obvious whether you are a child playing with a kaleidoscope or a Great Mogul emperor building the Taj Mahal as a monument to eternal love. That preference, as it turns out, greatly shapes how we see the world when items are in motion. More on that shortly.
In the natural, as opposed to manmade, world, symmetry--whether we see it in prey, predator, mate or mother--serves as an early-alert system, drawing your attention. Even an infant, who has blurry views of his or her surroundings because of not yet developed acuity, has an innate preference for symmetry. Babies stare longer at faces that have two eyes in the normal position than they do at those that have a cyclopean or a stacked-eyes configuration.
