Awareness Test | Attention Selective Test | Invisible Gorilla Style Test Optical Illusion

An awareness test in the style of the selective attention / invisible gorilla test by Daniel Simons. Do the test. See for yourself. This visual attention experiment will test your awareness of what you see, and more importantly, what you miss.

There are various versions of this optical illusion -- including the monkey business illusion and the moonwalking bear. The video shows the fascinating psychology of perceptual blindness by our brains when we are strongly focused on something. During times of intense focus, our brains can miss even the most obvious images in full visual view, as this experiment shows. It's amazing how our brains can be tricked into "selective visual" blindness.

Take the test and see how the strength of your awareness measures up.
