A recent study published in the journal Psychology of Aesthetics, Creativity, and the Arts provides evidence that the human brain applies different standards of beauty depending on the type of visual art it evaluates. By comparing the visual properties of historical building facades and artistic paintings, scientists found that architects and painters weigh aesthetic features like symmetry and complexity quite differently.
When people look at an image, their appreciation of its beauty relies on several visual variables. These variables include properties such as color, balance, symmetry, complexity, and the relationship between the main subject and its background. Psychological theories of visual perception propose that humans tend to prefer sensory properties that the brain can process easily.
“I have been interested in the Valuation System of the brain, the network that learns and deploys values for decision-making,” said Norberto Grzywacz, a professor of psychology at Loyola University Chicago. “In particular, I have had interests in aesthetic values, which this system also processes. At some point, I asked myself whether aesthetic values in a sensory domain, for example vision, are universal or specific to different domains.”
