Is the bee expanding

What is a visual illusion? It refers to a perception that is different in some aspects from the physical stimulus.

Some years ago, Neuroscientists at the University of Rochester came up with a new insight into the brain processes that make us think an image is expanding.

Watch video:

The yellow jacket (Rocky, the mascot of the University of Rochester) appears to be expanding in the video that alternates between an inward motion of a black and white circle and the bee.

But is it expanding? No, it is not

We only think the bee is growing because our eyes have adapted to the inward motion of the black-and-white circle.

The scientists said that similar illusions ‘arise constantly in our day-to-day lives’.

A common example of such a phenomenon in everyday life is that the world around us seems to be in motion when we jump off a treadmill.

The illusion you just saw is called Motion Aftereffect.

University of Rochester explained: “The yellow jacket (Rocky, the mascot of the University of Rochester) appears to be expanding. But he is not. He is staying still. We simply think he is growing because our brains have adapted to the inward motion of the background and that has become our new status quo. Similar situations arise constantly in our day-to-day lives — jump off a moving treadmill and everything around you seems to be in motion for a moment.”
