vest have created a new optical illusion that reveals how our brains evaluate the
material properties of an object.
Researchers at the
University of New South Wales made with the aid of the computer an image of an
object with a refractive index of glass. Then they put the image on a
photograph with a clear horizon.
Transparent or not
When people see
the picture, they think the object is made of transparent material. But turn
out to be the picture than the same object appears suddenly made of shiny,
opaque reflective material.
Above or below
"It's a brand
new optical illusion," says researcher Juno Kim. "And shows that the
visual system has learned to rely on the orientation of the horizon and or
bright spots are located at the top or bottom of an object, and on the basis
thereof determines the brain or objects are transparent or not. It shows that
our brain is wondering: which side is the top "?
"Our brain is
very advanced, but when the material properties of an object trying to distract
from impaired light patterns caused by reflection of light on the reflective
surface of the object, the yeast based on previous experiences. This
optical illusion seems to be driven by two major biases in the brain. The first
is the assumption that a light source shines generally from above. This bias is
the reason that people look scary and quite different under their chin. The
brain is accustomed to processing faces while light comes from above. And the second
bias is that most objects are generally spherical in shape. "
