Transcript of Optical Illusions

Optical Illusions
Different Type of Illusions
There are three types of illusion. This includes: literal optical illusions, physiological illusions, and cognitive illusions.
Different Types of Cognitive Illusions
Optical Illusions
Illusion: a thing that is or is likely to be wrongly perceived or interpreted

Optical: relating to sight, especially in relation to the physical action of light

Optical Illusion: something that deceives the eye by appearing to be other than it is.
Now You See The Magic
The magic we see performed by magicians is a form of optical illusions. They show us things that are not really there or that did not really happen, but we believe it because are eyes and minds are perceived to see what is visible not what is actual.
Literal Optical Illusion
Creates images that are different from the objects that make them
Physiological Illusions
effects of excessive stimulation of a specific type (brightness, color, size, position, tilt and movement)
Cognitive Illusions
The result of unconscious interference. These illusions are harder to find examples for as there are four different types of cognitive illusion
Distorting Illusions
Distortion in size, length, or curvature.
Ambiguous Illusions
pictures and objects that elicit a perpetual 'switch' between the alternative interpretations
Paradox Illusions
Paradox Illusions are formed by objects that are paradoxical or impossible.
Fictional Illusions
Fictional are commonly known as HALLUCINATIONS.
