Can you see the hidden 3D image in the stereogram above? Continue reading and the answer will be revealed…
Optical illusions help us understand how we perceive the world around us and why. Sometimes what we believe we are seeing, isn’t reality. Why does this happen? Our brain works to interpret everything we see, and sometimes shadows, lighting, shapes and other factors mislead that interpretation.
Our depth perception is challenged with stereograms. Finding 3D shapes within a 2-demensional image isn’t easy, but by staring at a repeating pattern in wallpaper, the brain is tricked into matching pairs of them to perceive a virtual plane behind it. This virtual plane is where the hidden image lies. This was discovered by Dr. Bela Julesz in 1959, which helped change the belief by most vision scientists at the time that depth perception solely occurs in the eye. It is now known that depth perception is a neurological process that occurs in the brain.
