Transcript of Optical Illusions

Optical Illusions Karly & Cameron What they Are:
Stare At Dot And See What Happens. An optical illusion
(also called a visual illusion)
is characterized by
visually perceived images
that differ from
objective reality. There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, tilt, color, movement), and cognitive illusions where the eye and brain make unconscious inferences. The Different Types
Many of us believe we are in perfect control of what our minds believe. But what happens when your mind is unable to determine what is impossible? Imagine what would happen if your mind suddenly overrides your conviction that something is false...

Well, that is exactly how the mind perceives optical illusions! So just how do these intriguing illusions work? Your brain is constantly interpreting everything you see, feel and hear. You rely on your mind for everything you do in your life from complex decision making and logic to the simplest tasks such as eating with a spoon. We take its incredible abilities for granted.

Take for instance, this building. It looks as though water is cascading down its side when actually its painted. So how are we fooled?It's because, we learn to process certain images automatically.

All through our lives, our minds learn to recognize and automatically process images. For instance, young children learn to distinguish unique features in individual faces. This is what is called hard wiring the brain. However, optical illusions defy this hard wiring of logic, creating numerous camouflage, ambiguous, and flip flop illusions. No matter what type the illusion may be, it relies on the mind struggling with image overcoming logic patterns ingrained in our thought process.
Normally, this process occurs without a hitch, but optical illusions are images that are presented in such a way that deprives our minds eye of enough information to prevent it from processing the information correctly. In the case of the the picture above, we see the shape of a spider, and assume it is emerging from the building

These lovely interior wall paintings are a fine example of how optical illusions can be used in interior decorating.
The meaning of this image flip flops between a skull and a couple sitting at a table. This 1920's French postcard image titled "L'Amour de Peirrot" was a popular motif throughout the 20th century and inspired such artists as surrealist Salvador Dali. The artist who created the image, ironically, is unknown.
Illusional Chalk Art is pretty cool! Illusional Trucks are Neat Too! Illusional Body Art! Wild...!!
The hand is easy to see, but the mind ignores it and focuses on the painted image.

This Russian body art is amazing!!
Whatever the reason, optical illusions will continue to amaze and fascinate us as well as make us wonder just how they really do manage to fool us.
The End!
