An artist, a neurosurgeon and a garden designer walk into a bar…
And probably grab a table and order a round of drinks. But the question is, why are they hanging out together in the first place? It turns out they have more in common than you might think.
In their August issue, Psychology Today reports on the exotic field of neuroaesthetics, which is seeking to determine why we respond to art the way that we do. According to the article, art makes use of certain visual tricks that engage our brains in a variety of specific ways. So what we describe vaguely as beauty or creativity can in part be explained by how our brains process visual information.
The article shares 10 perceptual principles of great art, but I’ll just touch on a few.
The Peak Shift Effect occurs because our brain responds more eagerly to exaggerations and distortions than to real world people and objects. Why? Because this helps us recognize things, thereby hyper-stimulating our senses. A Picasso that exaggerates distinctive elements is attractive to us in part because it makes it easier for us to recognize what it is.
Picasso's self portrait may appeal because it makes it easier to recognize him.
And isn’t that the essence of a garden? A garden is not a replica of the natural environment, but instead is an intentionally artificial construct that exaggerates many of the elements we enjoy in nature. It may take its cues from the natural world, but its more orderly form and visually distinct spaces are exactly what makes it pleasing to us.
The Peekaboo Principle plays upon the fact that we enjoy a visual mystery and often respond to art that lets us fill in some of the blanks for ourselves. (The same principle applies to erotica, but that’s a post for another type of blog.) An artistic example of this is Cezanne's paintings of Mont Sainte-Victoire, where the mountain is implied, but it is up to us to fill in the missing space.
Garden designers employ this same principle when they reveal part of a view, or create the sense that something interesting is happening just around the corner, creating a little puzzle that engages us more deeply in the space. In my designs, I like to give the impression that a garden exists beyond its actual borders. A simple means of accomplishing this is to extend the backyard a few feet around the edge of the house, encouraging the eye to believe there is more to be discovered, even if the reality is a utilitarian concrete slab home to to compost bins and garden rakes.
So if some of you are thinking all you need to do now is find out what the other eight principles are and Presto! you’re a great artist, or if like me your first thought was whether two years of design school was educational overkill, it’s probably a bit more complicated. By hooking up subjects to MRI machines and testing their response to great art vs. kitch, neuroscientists are currently conducting experiments to determine if our brains can perceive a difference between great art and schlock.
In the meantime, I’m getting back to my current design and focusing heavily on principle number eight, Repetition, Rhythm and Orderliness with a little Grouping and Generic Perspective thrown in for good measure.
