The expression, “Beauty is in the eye of the beholder,” has been used by many since it first appeared in print in the 19th century by writer Margaret Wolfe Hungerford. Cliché as it may sound, the idea behind this colloquialism—that perception is a subjective experience—is one that researchers are still working to unravel today. We’ve learned that aspects of perception (auditory, time, etc.) can be altered from depression, for example, and that there is a specific part of the brain dedicated solely to facial perception. Now, scientists are looking at differences in personality and how that affects the way a person visually examines a piece of artwork.
