Seeing Isn’t Always Believing

Cognitive scientists say that we can predict the future up to one-tenth of a second before something actually happens. Our brain is constantly slower than the things that happen around us, this means it takes a little while for our brain to convert what we see into what is actually happening right now.

The lag in what we see and what our brain processes are compensated by our brain’s motor system, it offsets the delay by predicting the events that are most likely to occur. It’s a useful evolutionary trait which has allowed us to close the one-tenth second gap between our sight and our mind.

Optical Illusions work by making our brain predict what should be happening in front of our eyes. The trick is that our mind’s perception does not match that of reality.

Live Science: Key to All Optical Illusions Discovered

Decisions Made Through the Eye

In the movie Blade Runner, The Voight-Kampf test was used to distinguish humans from replicants by testing the fluctuation of the pupils and the involuntary dilation of the iris.

Our pupils are known to dilate when we are under heavy stress as a part of the fight-or-flight response. Noradrenalin is a hormone found during times when our pupils dilate; it suggested that noradrenalin can also influence our memory and decision-making ability.

Pupils dilate when viewing optical illusions; in the spinning woman image (above), it is suggested that noradrenalin essentially makes us decide upon the direction the woman is spinning before it appears to actually happen.

Optical Illusions are the Simplest Form of Magic!

An optical illusion for you, a real trick to the senses wouldn’t you agree?


I just love optical Illusions. The experience is based on our sight and how our eyes interpret what we see. Optical illusions are all about perception and presentation, it’s the simplest form of magic!

The illusion of 3D in cinema is a hot topic these days but I won’t tell you how it works. It takes the magic out of the experience, and to be honest I really don’t know. I just know that the amount of technology used to trick our brain into seeing 3d images in cinemas is immense.
